Jinwoo Hong cef4416115 fix(mobile): name the narrow host header's controls and gate the drawer's hardware back on web (OTA phase C, C2.10) (#21729)
* fix(mobile): name the narrow host header's controls

The header renders two toolbars and the phone sees the narrow one,
whose controls carried neither a role nor a name. A screen reader could
not find them, and C2.9's render check could only assert their absence
at 390 px. The wide toolbar already names every control from the same
state, so the fix is to say the same thing rather than invent wording:
filter, sort, group, accounts, tasks and the search toggle take their
wide sibling's role and label expression verbatim.

The census names a seventh site the plan did not: the Reconnect button
in the status bar above both toolbars, which is shared rather than
narrow and has no wide sibling. It announces through its Text child
today, so it takes the role and the string it already renders.

No layout, style, handler or order changed; the diff is accessibility
props only.

The census parses the file with the TypeScript API and rules that every
Pressable carrying an onPress has a button role and a name, and that a
control both toolbars render is named the same way in both. It keys the
pairing on the handler, because that is what makes two elements the
same control, and asserts each shared handler is found exactly twice,
so a control deleted from one toolbar cannot leave the naming rule
comparing a group of one with itself. Red first, naming all seven
sites by path and line.

* fix(mobile): stop the right drawer arming hardware back on web

React Native Web logs "BackHandler is not supported on web and should
not be used." and returns an inert subscription, so inside the shell's
page every open of this drawer put that line on the console and armed
nothing. The gate is the one mounted-bottom-drawer and the file preview
already carry, with the same comment stating the degradation: there is
no hardware back in a WebView, and the shell owns the one the phone has.

The drawer had no render test. This one mocks react-native, the safe
area, gesture handler and Reanimated the way the bottom drawer's
hand-back test does, and reads the call rather than the console: on iOS
and on Android the handler is registered once for 'hardwareBackPress'
and released when the drawer hides, and on web it is never reached. The
three native cases are the control that keeps the web case honest; they
passed before the fix, which is what makes the single red meaningful.

* fix(mobile): type the right drawer test's element helper

The tests-typecheck ratchet was red on the previous commit: the drawer's
props declare `children` as required, so passing it as createElement's
third argument left no overload matching. It is a prop here, and the
helper answers a ReactElement rather than a return type borrowed from
createElement.

Test files sit outside `tsc --noEmit`, so only the ratchet sees this;
it is the gate that exists because a type-level pin in an unchecked
test proves nothing.

* fix(mobile): write the right drawer test in JSX

Lint was red on the previous commit and I ran it in the same command as
the commit, so it landed: passing `children` as a prop to satisfy the
type checker is exactly what react(no-children-prop) refuses. The
canonical form settles both, so the test is JSX in a .tsx file and the
drawer takes its body as a child again. The StyleSheet mock's generic
needs the trailing comma a .tsx file requires.

Re-proved in this form: with the web gate removed the web case fails
and the three native cases still pass.

* fix(mobile): derive the header's naming groups, and read a spread as unknown

Round 1, four folds.

The drawer's comment claimed the console line was observed inside the
shell's page. It was not: the drawer's one caller is the review screen,
whose route C4 serves, so no page closure reaches it today. The gate is
pre-emptive and now says so in its own words rather than borrowing the
bottom drawer's sentence.

The naming rule iterated a hand-written list, so it only ever compared
the six controls both toolbars render. Giving the two
`actions.openFloatingWorkspace` sites different labels left the census
green. The groups are derived from the discovered controls now, keyed
by the handler text, so any handler this header presses from more than
one place is compared and the failure prints both names. The declared
list stays as the precondition it always was: each of the six is found
exactly twice, which is what keeps the derived rule from holding
vacuously over a file with no repeated handler.

The scan read `Pressable` only and dropped any control whose `onPress`
read as empty text, which is what a spread reads as. It reads
`TouchableOpacity` too now, and a spread answers unknown rather than
absent: a control whose handler or whose accessibility props arrive
through one is kept, fails both rules, and prints `spread` rather than
`none`, so it can never be mistaken for a control the scan judged.

Red first on all four: the reviewer's disagreeing-label mutation, a
spread over the a11y props, a spread over the handler, an unlabelled
TouchableOpacity, and a shared control deleted from one toolbar.

* fix(mobile): read a braced-empty label as unnamed, from one shared reader

Round 2, two folds.

Only a bare `""` or an omitted attribute read as unnamed, so
`accessibilityLabel={undefined}`, `{''}` and an empty template all left
a control with nothing to announce and the census green. Reproduced on
both Tasks sites with each of the three shapes before the fix. The
reader unwraps a braced expression now: a string or a no-substitution
template answers its own text, and the identifier `undefined` answers
empty, so all three read as unnamed.

That reader was a near-verbatim copy in both censuses, which is how one
of them could have gained this rule and the other kept the hole. It
lives in one module under mobile-web-shell now, named for what it reads
and typechecked by mobile tsc rather than by the ratchet alone. Both
censuses import it and neither changed an assertion; their diffs are
the deleted copies and the import.

Red first, five mutations: the three empty shapes on both Tasks sites
here, and `{undefined}` and `{''}` on the tasks Back, which the page
census now catches too and did not before.

Jinwoo Hong 6a0200f416 test(mobile): certify the files page closure, 28 families and 125 goldens (OTA phase C, C3.2) (#21724)
* test(mobile): certify the files page closure, 28 families and 125 goldens

C3.2. The closure is re-derived at this base from the entries esbuild compiles —
the two `.web.tsx` files — and matches the design exactly: 28 families, 125
goldens, C1's 22 a strict subset, 6 families and 22 goldens added. Explorer
3441 modules / 304 local / 10 under `src/files`, preview 3666 / 330 / 19, union
342 local. No `mobileWeb.*` family appears, which is the tell that the native
switch was not measured.

Two tables at the route seam, as C2.6 splits its own: the explorer's one family
and the preview's five are separate evidence for two routes with separate
grants, and `c3-page-closure.ts` only spreads them over C1's.

C1's 22 families are inherited verbatim, not re-derived. Measured here, C2's
rule disagrees with 13 of those 103 pins — all 7 in `tasks.smart-source-search`,
all 5 in `host-worktree-refresh`, and `worktree-catalog-snapshot`. C5's
docstring says 10; corrected in this commit, comment-only. Every family C3
shares with C2 and with C5 is asserted equal object for object, and the three
committed pin files disagree on nothing.

Class totals: identical 66, result-absent-settlement 47, params-undefined 7,
result-absent-stream-release 3, write-ordinal 2. Pinned beside the per-id walk
because a table built wrong in a self-consistent way passes the walk.

Red-first, both halves: changing one verdict fails the totals and the
inheritance check by name; dropping a golden fails drift, totals and the census
count together.

What 125 certified does not say: `host-worktree-refresh`, inherited from C1, has
no byte-identical golden at all, so its 5 hold a class and not bytes. All six
families C3 adds have at least one. No scenario replays a save twice, so
`files.writeTerminalArtifact` is certified for one round trip and not for
idempotency; and no golden here subscribes, because the domain opens no stream.

The `config/scripts` precondition now derives both files routes and compares
their union against the C1 + C3 tables, with a second case proving each route
reaches a strict part of it — without which the union would pass with one route
contributing nothing.

Also folds pullfrog's open nit: the render check's comment claimed
`toContain('readme.md')` proved the encoded round trip, which a truncated path
would also satisfy; the url assertion beside it is what proves it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): share the pin-source reader and finish C5's 10-to-13 correction

Two pullfrog findings on #21724.

`c5-page-closure.test.ts` still said the rule disagrees on 10 of the 103; only
`c5-page-closure.ts` moved in the last commit, so C5's two files disagreed with
each other and with C2's and C3's. The sentence now states 13 with the same
breakdown the other three carry. No assertion depended on the number. While
there, the comment records why C5 compares against the imported object rather
than the committed text and is still sound: it inlines its families instead of
spreading C1's, so there is no spread for an edited entry to launder through.

`pinsFromSource` was byte-for-byte identical in C2's and C3's suites — checked,
not assumed — and is now one module both import. It sits beside
`page-closure.ts` rather than inside it, named for what it reads: the module it
would have joined holds pure table arithmetic and this one reaches the file
system. The C2 suite's cases and assertions are unchanged; its diff is the
deletion of the copy and one import.

The shared reader keeps its teeth: making the wrapped-entry capture unmatchable
reds the inheritance check in both composed suites, which is the defect the
comment describes — three `result-absent-stream-release` pins once went missing
that way with an empty mismatch list.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): name which leg of the path round trip each assertion proves

Round-1 nits 3 and 4. A second commit rather than a fold into `dc1de6e728`:
that one is already committed, and amending is off the table.

The render check's comment claimed the url assertion was the proof of the round
trip. It is the outbound leg only — what the page encoded into its own history —
and a screen that mis-decoded the middle of the path satisfies it and the title
assertion both. The comment says that now, and points at where the inbound leg
is proved instead: `mobile-file-path-route-encoding.test.ts`, which reads each
hazard shape back out of the href, and `mobile-file-preview-route.test.ts`,
which drives the normalizer the screen reads its params through. Both files
checked to exist, and read, before being cited.

The 10-to-13 edit left a 127-character line in a file that wraps at 100;
reflowed. It was the only over-length line the C3.2 commits introduced — the
others in both files predate this branch, and `oxfmt` accepts them because it
does not reflow comments.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say what the inheritance case is blind to, and finish the reflow

Round-1 item 3, plus a correction to my own claim.

The "inherits C1's families whole" case reads C1's committed text, which makes
it independent of the spread but not of C1's file: edit a verdict there and both
sides of the comparison move together. The docstring now says that, says what it
does catch — a C3 half redeclaring an inherited family, which the spread would
otherwise take silently from the last table — and names where the C1-file edit
is caught instead.

Both measured here rather than taken from the review. Flipping
`settings-repo-metadata-icons` in C1's file leaves this case green and reds
seven others: the class totals and the exclusion counts in C2's suite and this
one, both cross-series agreements, and C5's own inheritance case, which compares
against an independent literal rather than a spread. Redeclaring
`settings.repo-metadata` in the preview half reds this case along with five
more.

I also said last round that the 127-character line was the only over-length line
these commits introduced. That was wrong: I checked the two files in that commit
rather than the branch. Six lines over the 100-column wrap came in across four
files, including two I had just written in `c3-page-closure.test.ts`. All six are
reflowed, and the check is now over every line the branch adds rather than over
the files I happened to touch last.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state both redeclaration shapes, or neither count

Round 2's low finding. The docstring said redeclaring `settings.repo-metadata`
in the preview half reds this case "along with five more". The reviewer is right
that the number is shape-dependent, and right about both figures.

Re-measured, no truncation this time: one golden under the family's name reds
seven, because it also shrinks the census to 114 and leaves that family with no
byte-identical golden; the family copied verbatim with a single verdict flipped
reds five, the census unmoved at 125. The docstring states both with the reason
they differ, and says plainly that the count is not the claim — the load-bearing
half is that the spread takes the last table's entry and this case is what sees
it, which holds in both shapes.

The six came from reading a `head -6` of the failure list as the whole of it.
That is the same mistake in miniature as the one this file's own comments warn
about: an empty-looking result that was only a truncated one.

Jinwoo Hong 335d111265 fix(mobile): name the Back control in every page-served screen (OTA phase C, C2.8) (#21715)
* fix(mobile): name the Back control in every page-served screen

The C2.7 device proof could only reach the tasks Back by tapping the
native control's coordinates: inside the shell there is no native chrome
behind it, so a bare Pressable is absent from the accessibility tree and
a screen reader has nothing to announce. The agent-history panel's Back
carries a label but no role; the tasks one carries neither.

Both gain `accessibilityRole="button"`, and the tasks one the app's own
wording, `accessibilityLabel="Back"` — the spelling its thirteen
siblings use, including the agent-history panel this screen sits beside.
The host screen's Back already carried both and did not move.

The new census is a rule rather than a count: it finds every Back
affordance under the screen tree each page route serves — a Pressable
rendering a ChevronLeft that either carries the back-button style or
calls back — and requires a button role and a Back-shaped label on each.
Its coverage assertion reads MOBILE_WEB_PAGE_ROUTES, so a route
registered without a screen entry fails here, the way the flag census
fails for a switched route. Red first on both offenders by name.

Two tasks parity hashes move, and only the two a JSX prop must move:
`semantics` 3,272 -> 3,274 for the widened host signature and the two
new runtime strings, and the render-token stream 35,195 -> 35,203 for
the eight tokens the two attributes are. Hooks, statements,
declarations and styles hold, which is the evidence that nothing
executable changed. Recorded in the test's comment.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): judge a Back control by what it does, and name the files pair

Round 1 found the census discriminating on the ChevronLeft glyph, which
separates nothing: dismisses sit in the same header slot with the same
back-button style, so the rule claimed a dismiss and told it to be
called Back, while the explorer's Close escaped only by drawing an X.

The predicate is now the behaviour. A Back control is a Pressable whose
press handler reaches a back call — a `back()`, `goBack()` or `onBack()`
call, a handler named for one, or a local handler whose declaration
makes one — or whose label already says Back. A control matching
neither is outside the rule whatever it renders. The reviewer's
mutation, a dismiss with the back-button style wrapping a ChevronLeft
behind `onDismiss`, is claimed by the old predicate and passed over by
this one, which is the whole of the difference.

A spread now reads as unknown rather than absent, so a Pressable that
hides these props behind one is a Back control that fails both rules
instead of a control the scan never sees. No Pressable in the five
trees spreads today, so the branch is inert and load-bearing.

C3.1 registered the files explorer and preview, so the coverage
assertion went red on its merge, as designed. Both screens join
PAGE_SERVED_SCREENS and both Back controls gain
`accessibilityRole="button"`; they already carried `Back to session`
and `Back to files`. The tasks Back gains the `hitSlop={8}` its four
siblings carry, so its touch target is no longer the glyph alone.

Nine mutations: the dismiss stays out; a dropped role on each of the
five controls and a dropped label on the tasks one go red by name; a
spread fails both rules; a dropped table entry fails coverage; and
dropping the host screen's label — its only detector, since
`actions.leaveHost` is opaque — empties that tree and fails the
presence assertion rather than passing in silence.

Two parity hashes move for the one added prop and no count does:
`semantics` holds at 3,274 lines with one changed, the host signature
gaining `hitSlop`, and the render-token stream gains that attribute's
four tokens, 35,203 -> 35,207. Recorded in the test's comment.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): assert a Back per page route, not per screen directory

Round 2 found the presence assertion reading directories while two
routes share `src/files`, so the explorer's Back answered for the
preview's as well: rewriting the preview's control to `onPress=
{handleClose}` with `accessibilityLabel="Close"` left that route with
no accessible Back and the suite green. Reproduced exactly, then made
red by this change, which names the route and the module it failed in.

Each PAGE_SERVED_SCREENS entry now names the module that renders its
route's Back, and presence is asserted per entry. The rules still read
whole trees, so a Back added beside a screen is ruled as well as the
screen's own; the tree is derived from the module's directory rather
than declared twice. The failure prints the offending list instead of
comparing two values a reader cannot tell apart.

The doc comment claimed the preview was carried by the label half of
the predicate. It is not: `requestBack` is named for what it does, so
the preview is found behaviourally like the explorer, the tasks screen
and the agent-history panel. Dropping the label from each of those
three leaves it detected and failing the naming rule, which is the
evidence. Only the host screen depends on the label half, because
`actions.leaveHost` is a member access this rule does not follow.

The admitted residual gap stays admitted and the predicate is not
widened for it: a second Back control in a screen that already has one,
with an opaque handler and a label that does not say Back, is still
outside what this rule sees.

Jinwoo Hong ac024d4f05 feat(mobile): serve the files explorer and preview from the page (OTA phase C, C3.1) (#21710)
* refactor(mobile): take the files screens' router from the handoff seam

Inside the shell's page a screen is one document standing in for one screen, so
a target the page does not render has to be handed back to the app that does.
`useRouteHandoff` is where that decision lives, and its web sibling is the only
thing that makes it; both files screens held expo-router's own `useRouter`, so
on the web the explorer's Back and the preview's Back would post nothing and a
target outside the page would paint Unmatched over the page it is on.

Natively this is the same object — `route-handoff.ts` is `useRouter()` — so no
behaviour moves here, and `back()` stays expo-router's until the navigate-back
verb lands and the seam starts wrapping it.

A census rather than a behaviour test: neither screen's own tests can see the
difference, because a push that is never handed off still works for a target
inside the page. It walks this directory, refuses a value import of
expo-router, and names the two screens that must hold a router so a walk that
found nothing fails instead of passing empty.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): let the shell stand in for the two files routes

Both route files take the index.tsx shape — flag, MobileWebShellScreen, native
screen as fallback — and both gain the `.web.tsx` sibling that shape forces.

Inert until the manifest lists these routes: the shell answers `native-route`
for a route the bundle does not name, which is what `fallback` renders, and the
flag is `__DEV__`-only besides. Listing them waits on C2.3 and C2.5.

The sibling is not a precaution. The manifest defers every route behind
`import()`, so a native-only route module is invisible until the page opens
that route; the render check now opens both and, without the siblings, painted
`expo-modules-core.requireNativeViewManager is not available on web` instead of
the screen. That is also why the two cases render the route rather than
asserting a file exists.

The file path never becomes a path segment: only `hostId` and `worktreeId` are
spelled into the pathname, encoded, and everything else — `relativePath`,
`absolutePath`, `cwd`, `pathText` — is a param, which is how a `/`, a space or a
`..` stays out of the segment vocabulary the bridge holds a route to. The
preview render case proves the round trip on `docs/my notes/readme.md`.

`mobileFilePreviewShellParams` drops a param the normalizer left `undefined`
rather than sending it empty, because the page reads these back through
useLocalSearchParams where `line: ''` and no `line` are different screens. Its
test drives the normalizer rather than a hand-written literal: the literal omits
the key entirely, so it held with the filter removed.

The preview case also records what React Native Web says out loud — BackHandler
is inert on web, so Android back inside the page skips the unsaved-draft
prompt. Named in the assertion rather than filtered out, so closing it is a
change to that line.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): ask about an unsaved draft in the screen, not through Alert

React Native Web's `Alert` is `static alert() {}`. Inside the shell's page that
made Back with an unsaved terminal-artifact draft a button that did nothing at
all: no prompt, because the dialog is a no-op, and no navigation either, because
the code took the branch that shows one. Silently, with nothing on the console.

The prompt is now a row under the header. Not `ConfirmModal`, which every other
confirm here uses: that is a `BottomDrawer`, and C1.9 has Reanimated's animated
styles never reaching the DOM node on WKWebView, so on iOS in the page the
drawer parks off-screen and Back would be dead a second way. This paints the
same on every platform with no animation behind it.

Hardware back is registered natively only. React Native Web's
`BackHandler.addEventListener` logs "BackHandler is not supported on web and
should not be used." and hands back an inert subscription, so the guard never
armed there regardless; the render check asserted that console error on main and
now asserts none. The degradation is real and stated rather than hidden: Android
back inside the page pops the native stack without asking, and the page's own
Back control is where the question lives.

The decision moved to a hook so it is testable without a screen: the prompt also
drops itself when the draft it was about is saved or reverted, which is a state
`Alert` had no way to be in.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep expo-haptics' DOM shim out of the page

expo-haptics has a web build, and with no `navigator.vibrate` — iOS Safari,
which is the WebView the page runs in — it fakes a haptic by appending a hidden
`<label><input type="checkbox" switch>` to `document.head`, clicking it, and
removing it, once per call. C1.9 traced a long press that never fired on the
worktree list to exactly that stray click, and the file explorer calls
`triggerSelection` on every row tap, so C3 is the first domain to fire it per
tap rather than per long press.

`haptics.web.ts` answers the same five names with nothing. A phone holding the
page is a phone whose native app is right there with the real haptics, and a
missing tap feedback is worth less than a tap that does not register.

The test reads the shipped bytes rather than the import, because that is the
claim: with the override removed the bundle carries `ariaHidden` and
`pointer: coarse`; with it, neither, nor the `setAttribute("switch"` that does
the clicking. Not `navigator.vibrate` — react-native-web's own Vibration export
calls that and touches no DOM until something invokes it, which cost this test
one wrong red before it was narrowed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the files routes native when the page could not be given one

A file path is a param, so `/`, spaces and `..` all cross safely — but
`BRIDGE_MAX_ROUTE_PARAM_CHARS` is 1024 and a Windows long path is not bounded by
anything the user cannot exceed.

The symptom is not the blank document the design predicted, and the correction
matters: `bridge-host.ts` already parses the route against the page's own schema
and drops it to `null` when it fails, so `init` arrives naming no screen and the
page paints "Update Orca to open this workspace" — a wrong message about a fine
app, over a native screen that works. Deciding before the switch instead leaves
the route native, which is where every route starts.

The schema is the predicate rather than a copy of its bounds, so the rule cannot
drift from the half that matters, which is the half the page reads. The same
call also refuses a `worktreeId` the segment rule will not route: `..` survives
`encodeURIComponent`, which is the C1.8 class.

The tests assert the schema really refuses each input before asserting the guard
does, so neither case can pass by being impossible.

This belongs in the shell beside the schema; it is in the files domain while the
contract files are the C2 lane's.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin what keeps a file path out of the route vocabulary

Seven shapes, one case each rather than a representative: a plain path, a space,
a dot segment, an already-encoded slash, a fragment, non-ASCII, and an absolute
path. Each is checked in the two directions a path travels — the href the shell
writes into the page's history, and the href the page would hand back — for both
the pattern accepting it and the path coming back out of the query unchanged.

The counterfactual is in the file: the same paths spelled as a segment are
refused. Without that, the cases above would hold for a rule that was never
doing any work. Mutating `stringifyRouteHref` to join its query by hand instead
of through `URLSearchParams` fails three of them.

Also fixes two new test files the tests-typecheck ratchet caught: the partial
`react-native` mock needs a typed `addEventListener`, `act` will not take a
callback that returns a value, and `findAllByType('Pressable')` does not
typecheck against `ElementType` — the neighbouring files that do it are
grandfathered, so the tag comparison goes through a helper instead.

* fix(mobile): derive the discard prompt instead of clearing it in an effect

Both changed-code gate findings, which the lane had not run until the last
commit. React Doctor is right: the effect that cleared the prompt when the draft
went away adjusted state after a prop changed, so a save landing while the
prompt was up painted one frame still offering to discard nothing. The prompt is
now `asking && hasUnsavedDraft`, which cannot be stale by construction, and the
test that covers it passes unchanged.

The hoisted mock's `as` on a string literal is gone too: the literal narrows on
its own and the tests reassign it, so the holder is annotated instead.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): add the files routes to the hybrid shell flag census

The census pins every file that reads `useMobileWebShellEnabled`, because a
reader nobody listed is how a dark feature stops being dark. C3's two routes are
deliberate entries: each has a native screen behind it as `fallback`, and each
is inert until the manifest lists the route.

Found by the full mobile suite rather than by the files subset this lane had
been running per commit.

* feat(mobile): serve the files explorer and preview from the page

The last C3 commit: both routes join MOBILE_WEB_PAGE_ROUTES, and the shell
starts rendering the page for them on a phone with the dev flag on.

Grants are not the same for the two, and the difference is the point. Both take
`navigate` (Back pops the native stack, and the explorer's rows open the preview
beside it) and `storage` (the shared components the host layout renders above
them). Only the preview takes `externalLink`: a Markdown preview renders links
and `MobileMarkdown` opens them through the platform seam.

The explorer does not, and measuring is what says so rather than reading. Every
page route reaches `external-link.web.ts` — `/h/[hostId]` and agent-history
included, both granted nothing for it — because the protocol wall in the shared
host layout imports it. So closure membership is not the oracle for a grant; the
question is whether the route's own screens call it, and only the preview's do.
`MobileMarkdown` is in the preview closure and absent from the explorer's, which
the census now asserts in both directions.

Neither route writes a clipboard, so neither takes `native.clipboard.write`;
the census pins that as the absence of both `ExpoClipboard.web.js` and the
clipboard seam, with the tasks closure as the control that the probe can see one
when there is one.

The seam predicate moved into a module both censuses import rather than being
restated per series: two spellings of one rule drift, and this one is a regex.

Red-first: both manifest assertions failed on the new entries before they were
updated, and routing `MobileMarkdown` around the seam fails the preview's census
while leaving the explorer's passing, which is the asymmetry the grants encode.

Closure sizes as the page ships them, extensionless so the `.web.tsx` is what is
measured: explorer 3439 modules / 302 local / 10 under src/files, preview 3667 /
331 / 20.

* fix(mobile): read the files route's ids as one value and key the shell on them

Two round-1 findings, both reproduced before the fix.

A repeated query key reaches `useLocalSearchParams` as an array, and the
explorer read `hostId` and `worktreeId` bare. `String(['a','b'])` is `a,b`, so
the template built `/h/host-a%2Chost-b/files/wt-1%2Cwt-2` — a single segment the
bridge's rule accepts, and the shell would open a page for a host nobody has.
Read through `firstParam` now, as the tasks and agent-history switches do. The
preview already went through `singleParam` and is unchanged.

Neither switch keyed `MobileWebShellScreen`, where `index.tsx`, `tasks.tsx` and
agent-history all do. A host captures the grants its session opened with, so a
screen reused across a route change keeps authorising frames under the grants of
the route the page has left; only a remount drops that bridge. Both are keyed on
the route pathname now, with agent-history's reason.

The new route test is the agent-history one's shape. It caught both: the array
case landed on no route at all, because `name` was an array too and the schema
refuses a non-string param value, and the two lifecycle cases saw a prop update
where a remount was owed. It also needs agent-history's `lucide-react-native`
mock, since `firstParam` lives in the source-control barrel.

`name` is now omitted when empty rather than sent as `name=`, matching the two
switches beside it: an absent label lets the panel derive its own.

* fix(mobile): confirm a discarded draft with the app's own modal

Round-1 findings 3, 4, 5 and the minor one.

**ConfirmModal, not the bespoke row.** The row existed because C1.9 had
Reanimated's animated styles never reaching the DOM node on WKWebView, which
left every BottomDrawer parked off-screen. C1.10 (`b7c06900e2`, an ancestor of
this branch) fixed that with a dependency array on the mapper hooks, and the
drawer render check now holds it on WebKit as well as Chromium. With the reason
gone the row does not stand on its other merits: `Alert.alert` was modal on
native before the page existed, and the row quietly changed that for phones
too, so the app's own confirm is both the idiom and the closer behaviour.
`MobileFilePreviewDiscardPrompt`, its test and its thirty style keys are gone;
the hook's state machine and its tests are unchanged.

**The encoding test claimed more than it pinned.** Hand-joining the query reds
only three of the seven shapes; `docs/readme.md`, `../etc/passwd`,
`docs/日本語.md` and `/logs/run.txt` are encoding-neutral in the query, whose
pattern half is `[^#\s]*` and admits a slash, a dot segment and non-ASCII
verbatim. Rather than narrow the claim in a comment, the split is now pinned by
behaviour: each neutral shape must survive the query unencoded, each
load-bearing one must not. Moving `docs/readme.md` between the lists fails it.

**The manifest comment named one shared-layout opener and there are two.** The
New Workspace source field, which the sidebar renders on a wide layout, opens a
URL through the seam as well. Both are the shared layout's and every `/h` route
reaches both, `/h/[hostId]` included with no `externalLink`, so the tablet tap
is dead on all of them — recorded here as pre-existing rather than fixed, since
the grants do not move.

**Minor:** the dot-segment case in the guard test now asserts the schema refuses
the route before asserting the guard returns null, as the length case does.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop every page drawer logging a BackHandler error when it opens

Round-2 findings.

**The registration belongs to the drawer, and that is where the guard went.**
`mounted-bottom-drawer.tsx` armed `hardwareBackPress` whenever a drawer was
visible and interactive, with no platform check, so the hook's claim to have
dropped that console line held only while its prompt was closed — and every page
drawer since C1 has logged it on open. Platform-gated at the drawer now; the
hook's comment says so rather than claiming the credit.

**Nothing had ever opened a modal in a browser.** The render check next door
mounts both files routes and reads what they paint but taps nothing, so
`ConfirmModal` inside the page — a BottomDrawer, so Reanimated, a portal and a
gesture handler — was unproved. A new render file loads an editable terminal
artifact through the harness's scripted reply, edits it, taps the page's Back,
and asserts the prompt's title is up and no BackHandler line is on the console.
Red first on exactly that line; the prompt itself painted, which is also the
first proof on a browser that C1.10's fix carries a real drawer in the page. A
second case answers Stay and checks the draft survives. Its own file rather than
the render check's, which is at 482 of the 600-line cap; registered in pr.yml.

**The encoding rule was stated wrong.** Two rules decide it and neither is about
paths: the pattern's query half refuses whitespace and `#`, and
`URLSearchParams` is form-urlencoded, so it reinterprets `&`, `+` and a valid
`%XX`. `a+b.ts` reads back `a b.ts` and `a&b.ts` reads back `a`, so both are
load-bearing; `a=b.ts` and `a%b.ts` are not, because only the first `=` splits
the pair and a lone `%` begins no escape. A newline joins the load-bearing list
as the refused shape rather than the altered one.

**The web sibling read its params bare** where the native one uses `firstParam`.
Not reachable — the page only arrives through `init.route`, whose params are
already `Record<string, string>` — but the two files are meant to be one screen.

The preview keys on the pathname alone, and the comment now says why that is
enough: every caller in this tree pushes.

Closures after this: explorer 3441 / 304 / 10, preview 3666 / 330 / 19. The
explorer grew two modules because its web sibling now reaches `firstParam`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give the explorer the grants the preview needs, and key on the route

Bot findings, one of them a real gap.

**Pullfrog is right, and my grant oracle was half a rule.** Grants resolve once,
from the route the shell opened: `grantsForRoute` reads `session.routePathname`
and `init.grants.native` carries the answer for that session. The explorer's
rows push to the preview, and because the preview is a page route that push
stays inside the same document — no second `init`. So a preview opened that way
runs under the explorer's grants, and a Markdown link in it was refused by
`notifyExternalLink` with nothing on screen to say why. "Does the route's own
screen call it" was right for a route's own screens and wrong for the routes it
reaches in-page, so the explorer now declares `externalLink` as a transitive
grant, with the comment saying that rather than claiming it opens links. The
census pins the pair as a superset; removing the grant reds it.

**The seam regexes matched one quote style.** A double-quoted `react-native`
specifier walked past both censuses unseen. Both styles now, with the predicate
tested directly for the first time.

**The discard request outlived its draft.** `asking` stayed set after a save or
a revert, so the next edit re-showed the prompt with no Back request behind it.
The request is now dropped when the draft it was about goes, adjusted during
render rather than in an effect — the shape React Doctor named in the round-1
fold. Red first: save with the prompt up, edit again, prompt is back.

**CodeRabbit's keying comment is a correctness point, not the question I
answered.** The page learns its route exactly once, out of `init`, so a
same-path param change — another file in the same worktree — left the shell
mounted and the page still showing the file it was opened on. My comment claimed
"the screen reloads the preview from the param either way", which is true only
with the shell absent. Both switches key on the whole route now, params
included; two tests cover the same-path case and both red on a pathname-only
key.

`build-mobile-web-app-bundle.test.mjs` hit 601 of its 600-line cap on the way,
so the two manifest assertions now share one expected list instead of repeating
it. Closures unchanged: explorer 3441 / 304 / 10, preview 3666 / 330 / 19.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make the seam test import the module it is testing

Round 3.

**The blocker is mine and the reviewer's diagnosis is exact.** The seam
predicate test imported an absolute path into this lane's worktree. On CI that
module does not exist and it takes the whole `config/scripts` suite down; here
it resolved to the same file by accident, so the test was green against a tree
rather than against the checkout — which is why reverting the double-quote fix
left it passing and the predicate untested. Relative now, and proved: reverting
the fix in place reds both double-quoted cases, which is the first time this
test has failed for the right reason. Every file this PR touches is grepped for
`/Users/` and `orca-lanes`; none carries a path.

**Three comments outlived the grant change.** The two lists became equal when
the explorer took `externalLink`, so "longer than the explorer's" and "declared
with different grants" were both false. Corrected to what is actually true: the
lists are equal and the reasons are not — the preview has its own consumer in
`MobileMarkdown`, the explorer has none and declares the grant because its rows
push to the preview in-page.

**The duplicated serializer is pinned rather than imported.** `shellRouteHref`
lives in `page-bootstrap.ts` beside the page's RPC client and its document
channel, so a native route file importing it would pull both into the app. The
copy stays, and a test asserts the two agree on three routes; dropping the
empty-search branch reds it.

**Recorded, not fixed:** the sidebar `HostScreen` pushes to `/h/<id>/tasks`
through the handoff, which is local, so on a tablet the tasks page runs without
`native.clipboard.write` from any page route and its copy actions refuse
silently. Pre-existing since C2.1 for the worktree list and agent history. Named
in the explorer's manifest comment as the known remaining hop, with the fix
being a handoff rule in its own PR.

The equality pin needed `it.each<BridgeInitRoute>`: the inferred table is a
union whose members carry `?: undefined`, which the ratchet caught.

Jinwoo Hong 76063e7ab1 test(mobile): certify the tasks page closure, 70 families and 266 goldens (OTA phase C, C2.6) (#21712)
* test(mobile): read a page closure's run totals through one reader

The C5 gate counted the run's classes inline. C2 needs the same count over its
own closure, and two spellings of "what the run tallied" can disagree while both
stay green, so the loop moves next to `pageClosureTotals` where the table-side
count already lives.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): certify the tasks page closure, 70 families and 266 goldens

C2 moves the tasks screen to the web, so the goldens recorded at a call site
inside `app/h/[hostId]/tasks.web.tsx` and `app/h/_layout.tsx` are the ones whose
divergence would be this domain's. Each is pinned by id: the suite's own counts
run over 787, where one of the other 521 can pay for a closure golden that
stopped replaying.

C1's 22 families are inherited verbatim rather than re-derived — C2's rule
disagrees with them on 10 of the 103 — and the rule decides only the 48 this
domain adds. The pin is split at the domain's seam, one work item opened versus
choosing which to open, because the table is 409 lines of data and `max-lines`
is not a thing to disable.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): correct the C2 pin's inheritance count and census scope

Two comments overstated what was measured. The rule disagrees with 13 of C1's
103 inherited pins, not 10 — the 10 was copied from C5's file, which carries the
same error over the same 22 families — and the breakdown is now named so the
number can be re-derived rather than trusted.

The census reads the committed table and does not re-derive the closure, so a
golden arriving in a pinned family is caught while a new family entering the
closure is not. That was true and unsaid, which is the worse of the two.

* test: derive the tasks page closure's family set instead of trusting the pins

Round 2 folds, three.

The pin tables walk the families they already hold, so a scenario recorded at a
call site the route already imports lands in a family nobody pinned and every
assertion stays green. `mobileWebAppRouteClosure` runs in a quarter second and
`config/scripts` already imports it, so the derivation is now a test: the family
set the closure reaches must equal the union of the three committed tables.

C2's inheritance check read the object its own table spreads, which cannot
disagree with itself; it now reads C1's file as text. What that does and does
not hold is written down, because a verdict edited inside `c1-page-closure.ts`
is green there either way — C2 inherits whatever C1 commits. The gate's C1 block
gains the run-totals assertion C5 and C2 already had, which is the check that
edit does fail.

* ci: run the page-closure family check in the job that installs mobile deps

Its closure half asks `mobileWebAppDependenciesPresent()` first, so outside the

question into a failure.

Jinwoo Hong b6e8b1a7b2 feat(mobile): serve the tasks screen from the page, with its seams (OTA phase C, C2.1 + C2.5) (#21694)
* fix(mobile): encode the host id in the tasks workspace-creation href (OTA phase C, C2.1)

`use-mobile-tasks-workspace-create-actions.tsx` built
`/h/${hostId}/session/...` with the host id interpolated raw — the C1.2 class.
A host id carrying `/`, `#`, `?` or whitespace reaches the wire as an href
`BRIDGE_ROUTE_HREF_PATTERN` refuses, the handoff falls through to the local
router, and expo-router's Unmatched paints over the page.

Deleted rather than patched: `hostNewWorktreeSessionRoute` already builds
this exact href with both segments encoded, and already has the test that
pins it. The screen now calls it.

The census that caught it stays: no module under `src/tasks` may interpolate
into `/h/${...}` without encoding, which is the rule rather than this one
line. Three refactor-parity hashes move with the statement change and are
recorded in that file the way every earlier movement is.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): route the tasks tree's external links through the seam (OTA phase C, C2.1)

Ten of the twelve call sites in the tasks page closure: the nine under
`src/tasks`, swapped by one export in the dependency barrel, and
`MobileMarkdown.tsx`, which imports react-native directly and is edited in
place.

Inside the shell's WebView react-native-web's `openURL` calls
`window.open(url, '_blank')`, which both shells refuse — iOS returns nil from
`createWebViewWith`, Android false from `onCreateWindow` — and resolves
regardless. Every one of these sites would have reported success into a tap
that opened nothing.

The barrel's `Linking` is typed `{ openURL: (url: string) => void }`, so a
`.catch` on it is a compile error rather than a handler for a rejection that
cannot arrive; the seam names its own failures. `MobileMarkdown`'s own
`.catch(() => {})` goes with the swap for the same reason.

No parity hash moved: the barrel and `MobileMarkdown` are outside the
refactor-parity family's source set.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): route the shared screens' external links through the seam, with a census (OTA phase C, C2.1)

The last two of the twelve call sites in the tasks page closure:
`ProtocolBlockScreen.tsx` and the `openExternalUrl` prop wiring at
`host-screen-overlays.tsx`.

Both are shared with native routes and with the already-live `/h/[hostId]`
page, so this changes that page too: its external links go from the measured
`window.open` no-op — which both shells refuse and which resolves anyway — to
a URL handed to the shell. Nothing changes on a phone, where the seam is
`Linking.openURL` unchanged.

The `openExternalUrl` prop chain is retyped `(url: string) => void` with it,
and `SmartWorkspaceSourceField`'s `.catch(() => {})` goes: the seam names its
own failures and never rejects, so that was a handler for a rejection that
cannot arrive.

The census is the rule rather than today's twelve sites: no module in the
tasks page closure may reach react-native's `Linking`, by name or through a
namespace import. It reads the closure from a new builder export —
`metafile.inputs` for `_layout` plus the route, which is one definition of
what a page contains — and checks which module the name comes from, not which
text a call site writes, since the tasks tree still calls `Linking.openURL`
and that `Linking` is now the barrel's seam-backed export. Confirmed to
discriminate: restoring one react-native import turns it red.

A second case pins that the seam is in the closure, so an empty offender list
cannot also mean a page that reaches no link code at all.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): write the tasks clipboard through the shell's verb (OTA phase C, C2.1)

The two `Clipboard.setStringAsync` sites in the tasks page closure move onto
a seam, `src/platform/clipboard.ts` with a `.web.ts` sibling, registered in
the overrides.

A hook rather than a function because the web form needs the page's bridge
client, which is React context. Native is `expo-clipboard` unchanged. Web
calls `native.clipboard.write` through `useNativeVerbs`, because
`expo-clipboard` on the web is `navigator.clipboard` and needs a secure
context: the iOS shell serves the page from a custom scheme and Android from
`https`, so that path would work on one platform and silently not on the
other, with nothing at the call site able to tell.

Both seams reject rather than return false, and both call sites already wrap
the write in a `catch` that puts the message on screen — so a write that did
not land says so instead of showing "Copied". A route that has not declared
`native.clipboard.write` is refused before a frame is sent and lands in that
same `catch`; the route declares it in the entry commit.

Two parity hashes move, the hook list and the statement hash, each by one
entry, and are recorded in that file. `semantics` holds, as do render and
style: no RPC call, method literal or JSX host signature changed.

* feat(mobile): hand the tasks Back button to the shell (OTA phase C, C2.1)

The tasks header's `router.back()` reached expo-router through the dependency
barrel, and inside the page that moves nothing: the document holds the single
history entry the entry wrote with `replaceState`. The stack with somewhere
to go is the native one the shell pushed the page onto.

One line in the barrel, as with `Linking`: `useRouteHandoff` is router-shaped,
so every call site is unchanged. On a phone it is expo-router. Inside the page
it keeps a route the page renders and posts `navigate-back` for a Back the
document cannot serve — the C2.2 seam, which until now had no consumer.

No parity hash moved: the barrel is outside the refactor-parity source set,
and no call site changed.

* feat(mobile): render mermaid as its own source box on the web (OTA phase C, C2.5)

`MermaidDiagram` is in the tasks page closure, reached through
`MobileMarkdown`, and it renders the diagram inside a sandboxed `WebView`.
`react-native-webview` is a native component with no browser counterpart:
importing it runs a codegen lookup that throws, and the route manifest imports
every route, so one such import takes the whole page down rather than one
diagram.

The web sibling renders the labelled source box the native component already
falls back to on a parse or render error, with that component's own styles, so
the degradation looks like a state the product already has rather than a
second design.

Not a browser renderer, and the reason is not reach: mermaid is a browser
library and the engine bundle is vendored. It is that the native path's safety
comes from the WebView it runs in — `buildHtml` escapes `</script>` and the
U+2028/U+2029 separators because diagram source is untrusted agent and PR
content — and a DOM path has no such sandbox, so it needs its own escaping and
its own proof. That is a change of its own, not a smaller version of this one.

Registered in the overrides, whose gate fails on an unlisted `.web.*` file.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): turn the tasks route on for the page (OTA phase C, C2.1)

The entry: `/h/[hostId]/tasks` joins `MOBILE_WEB_PAGE_ROUTES`, the route file
becomes the shell's flag switch in `index.tsx`'s shape, and a `.web.tsx`
sibling renders the screen directly, registered in the overrides.

The screen moves to `src/tasks/MobileTasksScreen.tsx` first, verbatim — body
byte-identical, imports rewritten to `./`. It has to: under the builder's
`resolveExtensions` a web sibling importing `./tasks` resolves back to
itself, which is why every other shell route's screen already lives in `src`.

The parity family follows the file rather than the path. `TASKS_ROUTE` leaves
`MOBILE_TASKS_SOURCE_FILES` — `SOURCE_PATTERN` already matches
`MobileTasks*.tsx`, so listing it too would double-count — and the execution
reader points at the new file. Measured rather than predicted: all six
refactor-parity cases pass unchanged. No hash moved, including the family
text and declaration list, because the new name sorts where the route path
sat.

The route declares `navigate`, `storage`, `externalLink` and
`native.clipboard.write`, which the grammar fold made expressible and
per-route scoping makes meaningful: it is granted those and not the rest of
what this shell implements.

The browser check covers what only a browser answers — every module in the
closure evaluating under React Native Web, `taskSource` surviving the
handshake into the page's own URL, and the route's chunk arriving on a
client-side navigation. It states plainly what it does not cover: the three
seams are reached from controls that need provider data the double does not
serve, so a case posting those frames directly would prove the transport and
read as a tap it never performed. Both new checks join the `mobile_web_app`
job.

* fix(config): resolve a route closure the way the bundle ships it (OTA phase C, C2.1)

`mobileWebAppRouteClosure` took the route's explicit `.tsx` path as an entry
point, so esbuild used that file directly and `resolveExtensions` never ran.
For a route with a `.web.tsx` sibling that measured the native switch, which
no browser loads: the tasks closure came back carrying
`MobileWebShellScreen`, and with it a `Linking` import the census then
reported as an offender.

Extensionless now, so the closure is the one the page actually contains:
3775 modules, 428 local, with `external-link.web.ts` and `clipboard.web.ts`
in it and the shell screen out.

The route-manifest pins move with the tasks route joining
`MOBILE_WEB_PAGE_ROUTES`, in both the declaration check and the built
manifest.

* fix(mobile): cover the clipboard seam, close two page escapes, share the mermaid props (OTA phase C, C2.1)

Four from round 1.

The clipboard seam shipped untested. Both halves have one now: the native
form rejects when `setStringAsync` answers false and resolves when it does
not, and the web form is driven through the real port pair — resolving on a
reply, rejecting when the shell says the pasteboard refused, and rejecting on
an ungranted route without putting a frame on the wire.

The tasks barrel still re-exported `expo-clipboard` with no consumer, which
kept `ExpoClipboard.web.js` — the `navigator.clipboard` path this series
exists to avoid — inside the page closure. Deleted, and asserted as the
module's absence from that closure rather than as a count of importers: a new
import puts the file back whoever writes it.

`ProtocolBlockScreen` reached expo-router's singleton for its way out to the
host list. A singleton is the one shape the handoff cannot intercept — it is
not a hook, so the page's bridge client is never consulted — and `/` is a
route the page does not carry, so inside the shell that replace rendered the
root route in the WebView instead of leaving it. Pre-existing and live via
`/h/[hostId]`; routed through the handoff now. Two suites' `expo-router`
mocks gain the hook the handoff reads.

`MermaidDiagram.web.tsx` redeclared its props; it imports the native
component's type, so drift fails tsc.

No parity hash moved: none of these files is in the refactor-parity source
set.

* fix(mobile): close the href census gap, read route params through firstParam (OTA phase C, C2.1)

Five from round 2, two of them real.

The raw-interpolation census inspected only the leading `${...}`, so
`` `/h/${encodeURIComponent(hostId)}/session/${worktreeId}` `` passed it — and
a worktree id carrying `/`, `#`, `?` or whitespace breaks the href exactly as
a host id does. It now refuses any hand-built `/h/...` template with any
interpolation left raw, whichever segment it is. Proved against exactly that
shape in a throwaway before the change, which the old rule admitted.

The tasks switch read `hostId` and `taskSource` as plain strings. expo-router
hands back an array for a repeated query key, so a duplicate `?hostId=` built
`/h/host-a%2Chost-b/tasks`; both go through `firstParam` now, as the
agent-history switch does. `index.tsx` is untouched, per the Phase D list.

Three in the render check's prose: the header claimed the browser proves the
three seams fire from a tap, which the file's own closing note denies; a
module count repeated a number the closure test already pins; and a `replies`
parameter was threaded through without ever being supplied.

NeilandSudoAI-DEV ae9c06c941 feat(omp): discover and switch native-chat models on desktop and mobile (#20612)
* fix(omp): discover and switch native-chat models

Report the running OMP provider/model and discover available choices on
the execution host for desktop and mobile. Register an extension command
to switch through the OMP API because its TUI does not accept /model args.
Advertise that command in status so older hosts remain read-only.

Addresses the OMP portion of #17603; Pi chat enablement remains separate.
Model reporting begins on lifecycle activity; no startup status is invented.

Jinwoo Hong c22c442fdb feat(mobile): answer native verbs on the shell, clipboard first (OTA phase C, C2.4) (#21623)
* feat(mobile): declare the native verb table and advertise it (OTA phase C, C2.4)

The contract half of the shell-answered request seam: the `native.` prefix, a
typed table with params and result schemas per verb, and the two clipboard
verbs.

`MOBILE_WEB_SHELL_GRANTS` spreads the table's own name tuple rather than
restating it, so a verb cannot be advertised without a row and a row cannot
exist unadvertised — the table is `Record<BridgeNativeVerb, …>`, so a missing
row does not compile, and the suite holds the other direction. Verb names go
in the flat grant list on purpose: a route may declare one, and a shell that
lacks it keeps that route native rather than walling it.

The mime shape admits `image` because a later build will serve one; this one
refuses it, and the reason will say out of scope rather than unsupported,
since `expo-clipboard` implements the image calls.

No frame kind is added and no protocol version moves.

* feat(mobile): answer native verbs on the shell and fence them from the desktop (OTA phase C, C2.4)

The host half of the seam. `forward()` is the one place a request reaches the
client, so the `native.` check sits there and nothing about ids, caps,
settlement or cancel moves: a native request takes a pending slot and settles
on the same frames as a forwarded one.

`readBridgeNativeVerbCall` is the whole decision, separate from the host so
the `ungranted` arm can be exercised at all — every page is offered every
verb this build implements, so through a real host that arm is unreachable
today and is the point of the check once a grant is per-route.

Refusals carry `native_verb_refused`, which the desktop's vocabulary does not
contain: an unlisted method comes back from `MOBILE_RPC_METHOD_ALLOWLIST` as
`forbidden`, so reusing that would make a leaked fence read as an ordinary
scope refusal. Every case in the host suite reads `client.requests` for the
same reason.

`_meta` is omitted from host-authored replies per the ruling, which required
making it optional on `RpcSuccess`/`RpcFailure`: the type required a field the
wire never has. `isRpcResponse` does not read it, `runtime-rpc-envelope`
already makes it optional on a failure, and nothing in this app reads it —
every occurrence is a fixture writing one. Zero other type errors resulted.

* fix(mobile): restore the harness verb-type import and drop an unused one

Two leftovers from threading the native reply type through and then removing
it: the host harness lost its `BridgeNativeVerb` import, and the request
module kept a type import nothing uses. `tsc` and oxlint both failed on the
previous commit; this is the follow-up rather than an amend.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): typecheck the native verb suites and drop the dead reply type

Three leftovers the ratchet caught, none visible to `tsc -p tsconfig.json`,
which excludes test files:

- the fence suite read `frame.payload` off the whole `reply` union, and a
  chunked reply has no `payload`; it narrows on the field now
- the bridge hook's own suite builds its caller options inline and had no
  `serveNativeVerb`
- `BridgeHostAuthoredReply` became unused once `_meta` was optional, and an
  exported type nothing reads is the pattern round 2 of C2.3 flagged; the
  statement it carried already lives in the verb table's header

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): give the page a typed surface for the native verbs (OTA phase C, C2.4)

`useNativeVerbs` is the page's side, typed from the same table the host
serves, so a verb cannot be called with params the shell will refuse.

Each call goes out as an ordinary `request` and settles on the ordinary
frames; the method name is the whole difference. A verb the shell did not
grant is refused before a frame is sent, because a rejection after a round
trip and one that never left look identical to an `await` and only the first
costs an in-flight slot — `granted` is exposed so a caller can pick its own
fallback instead.

Results are parsed rather than trusted: the shell is a different build than
the page, and a result shape that moved should fail at the seam rather than
halfway through a screen reading a field that is not there.

No call site uses it yet; the two `Clipboard.setStringAsync` sites are the
consumer PR's.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): send native verbs from the module that owns the request port (OTA phase C, C2.4)

`use-native-verbs.ts` called `client.sendRequest` directly, which the
unvalidated-request-port boundary refuses: new code must send through an
`RpcOperation`, and nothing may be added to the inventory.

An `RpcOperation` is not available to this seam. Its `method` is typed
`RpcMethodName`, which is `keyof typeof RPC_PARAMS_BY_METHOD` from the
desktop's generated params catalog. Putting `native.clipboard.read` there
would declare that the desktop serves a method the whole fence exists to keep
off it.

So the send moves into `bridge-rpc-client.ts`, already listed as an owner of
the port — a module that implements the port rather than a call site picking
its own method and acceptance. `callNativeVerb` rides the same frame, id
space and in-flight cap as any request, and the page surface stays a thin
typed wrapper that reaches no raw port.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): fence native methods on subscribe, not only on request (OTA phase C, C2.4)

The fence sat in `forward()`, which is the one place a *request* reaches the
client. A `subscribe` reaches the same client by another door: a frame naming
`native.clipboard.read` opened a real stream on the desktop, and because
`client.requests` stayed empty the whole suite read as green over it.

Refused in `handleSubscribe` before the id is claimed, under the same
`native_verb_refused` code, so nothing about the frame reaches the desktop or
occupies a slot. Cancel needs no arm of its own: it can only settle an id
that was admitted, and none is.

The oracle is widened with it. Every case now reads the client's streams as
well as its requests, because the old one could not see this at all — an
absence that only ever looked at half the boundary.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold a native verb's answer to the result it declares (OTA phase C, C2.4)

The table names a result schema per verb and the host never applied it, so a
handler could answer `{ nonsense: 1 }` and the page's own parse would be the
first to notice — halfway through a screen, not at the seam.

Validated on the host and refused by name on a mismatch, which is what makes
the table's claim true on the side that serves it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the native verb member from being a raw port (OTA phase C, C2.4)

`callNativeVerb(verb: string, params: unknown)` took any method, so
`callNativeVerb('worktree.list', …)` reached the desktop through the real
pair — a raw request port in the one module allowed to hold one, and invisible
to the inventory, whose scan counts `.sendRequest` shapes and not a bare
call inside the owner.

The parameter is typed `BridgeNativeVerb` now, which is the fence for every
caller the compiler can see, and the prefix is checked at runtime for one
that reached the member through a widened type. The compile-time half is
pinned by a `@ts-expect-error` the tests-typecheck ratchet holds: widening
the parameter back makes that directive unused and fails there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give every native verb refusal one typed error at the page (OTA phase C, C2.4)

Only the seam's own refusal carried `native_verb_refused`. A handler that
declined and a reply too large to send arrived as other categories with no
code at all, and the hook rethrew a bare `Error(message)` — so a caller
telling an out-of-scope mime from an unsendable clipboard had to read message
text, and those want different handling.

Three changes, one shape. The host re-raises a handler's failure under the
seam's code, keeping the handler's message because that is what says why.
`BridgeReplyUndeliverableError` carries its frame refusal as a code, so
`reply-too-large` survives to the page. The hook throws `NativeVerbError`
with a `reason` read off the code `reconstructBridgeError` already copies
onto the rejection, plus `ungranted` for the arm this side decides.

Removes the unreachable `ok: false` branch from the hook with it. The
narrowing it was doing moves into the client member, which now promises a
success or a rejection and nothing else.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): test the in-flight cap and cancel, not the duplicate-id branch (OTA phase C, C2.4)

The case named for the cap sent the same id twice, so what it exercised was
the already-in-flight check. It never held a second slot and would have
passed against a seam that took none.

It now fills the cap with distinct ids against a handler that never settles,
and asserts the one over it is refused with the cap's own message. A cancel
case goes with it: a native request cancelled before its handler settles
posts nothing afterwards, the way a forwarded one does not answer an
exchange the page has moved on from.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the native verb member's type with a directive, not a cast

The case proving a desktop method cannot go through `callNativeVerb` reached
the runtime guard with `as never`, which the casting gate refuses — and a
cast is the wrong tool anyway: it asserts past the very type the case exists
to pin.

`@ts-expect-error` instead, which the tests-typecheck ratchet holds: widening
the parameter back to `string` makes the directive unused and fails there.
The call still runs, so the runtime guard is exercised too.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): parse the shell's error code instead of reaching for it (OTA phase C, C2.4)

The anti-slop audit refuses `Reflect.get`: dynamic input is parsed into a
named shape before it is read. `code` is not a property of `Error` — it is
whatever `reconstructBridgeError` copied onto the rejection from the capture
— so a schema is the honest reader here, and it says what this takes without
asserting the rest away.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): name the id collision before the native fence on subscribe (OTA phase C, C2.4)

The fence ran before the already-in-flight check, so a `subscribe` naming a
`native.` method under a live request's id settled that request with the
fence's message. The page lost the request either way — the collision class
predates this PR — but it was told the wrong cause, which is the difference
between a bug it can see and one it cannot.

Collision first. The fence still runs before any slot is taken, so nothing
about the frame reaches the desktop.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): parse a native verb result once, inside the catch (OTA phase C, C2.4)

The result was parsed twice: by the send path against the table's schema, and
again at each caller against the concrete one. The second parse was dead, and
it sat outside `call`'s catch, so a shell answering a shape the page did not
expect would have escaped as a bare `ZodError` — the one shape this surface
promises not to throw.

`call` takes the verb's result schema and parses once, inside the catch, so
every failure leaves as a `NativeVerbError`. The params parse at the callers
goes with it; the host validates params and the page builds them typed.

Also moves the comment block documenting `onExternalLink` back above it,
which `serveNativeVerb` had landed in front of.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give every native verb refusal its own code, and keep handler words on the device (OTA phase C, C2.4)

Two findings that had to land together. Six faults all arrived as
`native_verb_refused` and differed only in message text, which the hook's own
comment said nobody may switch on. And a handler's message crossed verbatim:
a clipboard read that failed after reading is free to put what it read in its
error, and the error frame is the only path out of this seam that is not a
declared result.

So each fault gets a code — unknown verb, ungranted, bad params, wrong
result, out of scope, handler failure, native-on-subscribe — and the three
paths that reached the page uncoded get one too: the in-flight cap, a
non-native method through a widened member, and host disposal. `reason` is
now drawn from a declared list with no `unknown` arm, asserted at the hook.

A handler's code crosses and its message does not; the shell logs the real
one. The out-of-scope mime stays distinguishable because the code carries it,
not the text.

`bridge-host.ts` crossed the line cap with this, so the serving half moves to
`bridge-host-native-verbs.ts` — read the call, serve it, hold the answer to
what the verb declares — leaving the host the frames around it. No cap was
disabled or raised.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): refuse unknown verb params, and floor an unknown code (OTA phase C, C2.4)

Two the bots caught, both about a shape one side does not know.

`z.object` strips unknown keys, so `{ mime, value, unexpected }` dispatched
as if the extra key had not been sent — and the page and the shell are
separate builds, so a param the shell silently ignores is the shape of a verb
that changed underneath a page. `z.strictObject` on the verb params and
results.

And the page passed any code through as `reason`, while its own doc and
`NATIVE_VERB_REASONS` promised a closed list; a shell newer than the page
would have fallen off the end of a caller's switch. Unrecognised codes floor
to `unreported`, `reason` is typed to the list, and the doc says what the list
actually is rather than the single code the per-arm ones replaced.

The flooring is tested by delivering the frame such a shell would send: this
build's host normalises an unknown code before it leaves, so the pair cannot
produce one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): serve no request before the page has asked for a session (OTA phase C, C2.4)

`serving` starts true so a page's first frames are not refused for arriving in
the same native batch as its `ready`, but nothing checked whether an `init`
had ever been sent. So a request from a document this host had told no caps,
no grants and no route was forwarded to the desktop, or served as a native
verb, while the notify path had refused exactly that since C0.

Gated on `initSent`, under the protocol's own `before-ready` name. Streams are
left alone: the finding names requests, and gating `subscribe` too is a wider
change than it asked for — worth its own decision, since the same hole is
there.

Fourteen host cases and five hook cases were relying on this: they open a
request without ever asking for a session, which no real page does. They take
a `ready` now, through a harness option, and the counts that read what the
host posted account for the `init` a session opens with.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): grant a page session what its route declared, not what the app can do (OTA phase C, C2.4)

`init.grants.native` handed every session the shell's whole capability set,
so a route declaring only `navigate` and `storage` was granted
`native.clipboard.read` as well. That was harmless while every grant was a
navigation or a write the page could make anyway. It stopped being harmless
the moment a verb reads something back, which is this PR.

The session is now granted the intersection of what this shell implements and
what the mounted route declared in `MOBILE_WEB_PAGE_ROUTES`, plus the
protocol's own `fault`. One list: `init` issues it and every grant check —
notify and native verb — reads the same one, so what a page is told it may do
and what it will be served cannot drift.

`MOBILE_WEB_SHELL_GRANTS` and `implementsGrant` are unchanged; the shell's
capability set is still the ceiling a route's list is drawn from.

User-mediated authorization is not attempted here and goes to C2.7 as an open
question.

`use-mobile-web-shell-session.ts` crossed the line cap with the extra field,
so the three effect workers that touch the network and the disk move to
`mobile-web-shell-session-effects.ts`, leaving the hook its reducer and
callbacks. No cap was disabled or raised.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): key the pre-handshake refusal on the session, and apply it to streams (OTA phase C, C2.4)

Two rulings, one mechanism.

The gate keyed on the host instance, and a host is rebuilt whenever the client
under it changes. The page does not know: the session id is the same, so it
neither re-handshakes nor hears that the shell was replaced. So a live page's
next request was refused, and would have been until reload — a regression, not
a safety gain, and not covered by the in-flight settling as delivery-unknown.
The host now inherits whether its session already handshook, which the hook
records when the page first asks.

And the rule is about the session rather than the frame kind, so `subscribe`
is gated with `request`: a stream opened before the handshake was the same
hole.

Fourteen stream cases were exercising a state the protocol forbids — they
subscribe without ever asking for a session, which no page does. Every one is
about caps, backpressure windows, acks, cancel, idempotency or arity; none
was testing anything through the hole itself. They complete the handshake
now, and the counts that read what the host posted account for the `init`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): judge a cached fallback by its own routes and grants (OTA phase C, C2.4)

The newer manifest is read before the download is attempted, so its
`pageRoutes` and `routeGrants` are already on the session when the download
fails. Opening the cached generation then mounted an older page under a newer
bundle's grants: a cached route that never declared the clipboard would have
been granted it by a manifest it is not running.

The fallback now derives both from `cached.routes`, and applies that
generation's own render eligibility before mounting it — a route only the
newer bundle claims is not a route the cached page can serve.

This is the Phase D "grants across generations" item arriving early. Only the
grant side is fixed here; persisting a generation's grants with the
generation itself stays Phase D's.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): remount the shell on a route change, so its bridge cannot outlive it (OTA phase C, C2.4)

A host captures the grants its session was opened with, and the agent-history
route renders `MobileWebShellScreen` with a pathname derived from
`worktreeId` and no key. So changing worktree updated the screen in place:
the old bridge stayed mounted and kept authorising frames under the grants of
the route the page had already left.

Keyed on the route now, which makes the change a remount — the old bridge is
disposed in the commit, before it can read another frame, and the new session
starts with no grants until its own `init`. The worktree-list and embedded-
browser routes are keyed on the host id for the same reason; the hazard is
the same whenever a dynamic segment moves under a mounted shell.

The probe that catches this uses an empty dependency array on purpose: keyed
on the pathname it re-fires on a prop update and reads exactly like a
remount, which is the one thing it exists to tell apart.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(shared): let a manifest declare a native verb as a route grant (OTA phase C, C2.4)

`GRANT_NAME_PATTERN` was dotless, and the contract's own pin asserted a
dotted grant is refused. So no manifest the desktop can produce could declare
`native.clipboard.write` — and once grants are scoped per route, a verb no
route can name is a verb no route is ever granted. Every native verb was
unreachable for every route.

The grammar now admits the verb shape the table names: `native.` followed by
at least two lowercase dotted segments, which is `native.<domain>.<action>`.
A plain name wearing a dot is still refused, `native.navigate` included, so
the pin keeps its meaning.

Wire compatibility, checked rather than assumed: widening what a manifest
field may contain is a new optional value reaching readers that shipped
before it, and the phone's reader already tolerates one. Its route schema
bounds a grant's length and nothing else, deliberately — an unknown name is
not a parse failure that would refuse the whole bundle, it is a grant this
build does not implement, so `implementsGrant` drops it and the route stays
native. Both halves are now tested: an unknown verb leaves its route native
and grants nothing, and a known one reaches `init.grants.native`.

* test(mobile): split the session reducer suite by concern before main pushes it over the cap

Merged with main the reducer suite reaches 805 lines against a cap of 800 —
neither side alone crosses it, which is the case the lane rules warn about.

Split at a concern boundary rather than raised: the grant-facing cases (the
cached fallback's own routes, and a manifest verb reaching the session
grants) move to `mobile-web-shell-session-grants.test.ts`, and the fixtures
both suites drive the reducer with move to a shared module beside them, the
way the bridge host suites already share a harness.

Jinwoo Hong 62903b7cf6 test(mobile): pin the agent-history page closure golden by golden (OTA phase C, C5.2) (#21649)
* test(mobile): pin the C5 page closure golden by golden (OTA phase C, C5.2)

The suite next door proves the corpus replays byte-identically or in a named
class, as counts over 787 goldens. A count cannot tell this domain's regression
from another domain's improvement, so the 134 recorded at a call site the
agent-history page owns are pinned by id, the way C1's 103 are.

Re-derived at this base rather than taken from the design: 3510 modules, 370
local, 16 under `src/agent-history`, 27 families, 134 goldens. The design measured
3508 / 368 at `889c2b562f`; the two new local modules are `omp-draft-launch.ts`
and `omp-fresh-launch.ts`, which arrived on main, and no family or golden moved.
The `.web.tsx` sibling is the entry: the native file reaches `MobileWebShellScreen`
and pulls the shell in, which adds 46 local modules and the two `mobileWeb.*`
families the C1 docstring excludes by name — so measuring the wrong one of the two
gives the right pin table and a wrong module count.

C1's 22 families are inherited verbatim rather than re-derived. Deriving them from
C2's classification rule disagrees with the committed file on 10 of its 103 pins,
in three ways that are each a true statement read too far: `tasks.smart-source
-search` is a `params-undefined` family and the rule's list of those is the five
C2 adds, not C1's one; `host-worktree-refresh` carries `write-ordinal` and
`result-absent-stream-release` goldens, classes the rule does not model because no
family C2 adds carries one; and "a scenario scripting `{ ok: true }` with no
result" is a property of the scenario a golden derives from, not of its family, so
reading it family-wide moves `worktree-catalog-snapshot`. The rule decides the
five families C5 adds and nothing else.

`c5PageClosureTotals` is pinned beside the per-id walk, and the gate asserts the
run's own class counts over this closure against it. A per-id walk agrees with a
table that is wrong the same way twice: deriving this file with a reader that
skipped `c1-page-closure.ts`'s wrapped entries produced an empty mismatch list, 53
`result-absent-settlement` and 0 `result-absent-stream-release` where the truth is
50 and 3. Only the counts showed it, so only the counts can guard it.

Both halves proved red, not assumed. A verdict changed in the pin fails the gate
as "aivault-history-scan-fulfilled: pinned params-undefined, ran identical"; a
golden dropped from the pin fails three ways — the drift names it, the totals move
72 to 71, and the census count fails.

Tallies untouched: 787 goldens, 396 / 341 / 3 / 6 / 33 / 8, unclassified 0. No
golden moved and nothing under `mobile/rpc-foundation/` was written.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): give both page closures one drift, not two copies

Round 1 on #21649. C5's pin file arrived with C1's type alias, observation type,
exclusions walk and drift walk copied across, identical but for the names. The
copies are the problem rather than the duplication: these pins are the instrument
two domains argue with when a golden moves between families they share, and C5's
closure contains C1's 22 families entire — so two spellings of "what drifted" can
disagree about the same goldens while both stay green.

`page-closure.ts` now holds the types and four helpers, each taking the pins as an
argument; `pageClosureTotals` moves there too, since it is a general question and
was C5's only real addition. `readPageClosure` joins them: the gate had grown a
local helper to print one domain's line, which is the same shape one step later.
Both pin files are now their table and nothing else, which is the part that is
per series and meant to be read as a diff.

Output asserted rather than assumed. The gate's two closure lines are byte-
identical before and after — "C1 page closure: 103 goldens in 22 families, 54
byte-identical" and "C5 page closure: 134 goldens in 27 families, 72
byte-identical" — diffed as files, and both pin suites report the same 60 cases

* test(mobile): read a golden's family through the corpus's own reader

Round 1 on #21649. Both pin tests parsed a golden file and asserted its shape in
order to read one field, each with a `SAFETY` annotation saying every golden
carries `family`. `readGolden` already answers that question properly: it checks
the format version and the value pool and throws a named diagnostic otherwise,
and returns `family` typed.

Both annotations are gone rather than reworded. C1's is fixed in the same commit
because it is the same line — the cast arrived in C5's file by being copied from
it, and leaving the original would have kept the shape that produced the copy.

The assertion is also stronger than it was. Before, a golden whose format version
had moved would still be read and its `family` compared; now that file fails with
the reader's own message instead of being silently accepted.

Checked that it still discriminates rather than assuming: renaming one family in
the pin fails two cases, the corpus-family read among them.

Jinwoo Hong 211821dc17 feat(mobile): render agent session history from the desktop's bundle (OTA phase C, C5.1) (#21596)
* fix(mobile): refuse a page target the shell will not take instead of opening it here

`useRouteHandoff`'s web sibling answered two things — handed off, or push it
locally — and fell through to the local router for three different reasons. Only
one of them is a page route. An href the protocol's own pattern drops and a shell
that answered no are the page reaching past what this shell can serve, and the
bundle carries every route under `app/h`, so the fallback does not paint
Unmatched: it mounts `session/[worktreeId]` on React Native Web inside the shell.

The outcome is now tri-state. A target outside `pageRoutes` is never pushed
locally; the page stays where it is and names the reason once per client, which
is the bound the other page-side reporters take.

Proved in the render check against the real bundle: with the double granting no
`navigate`, "Back to hosts" left the host route for `/` and painted Unmatched
before this, and now stays put, posts nothing and reports no page fault.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): encode the host id the worktree row's navigation actions build

Both targets this sheet offers interpolated `hostId` raw — the C1.2 class the
C1.8 stack fixed at the route files and `web.tsx`, at the last two sites that
still had it. `useLocalSearchParams` answers the decoded value, so a deep-linked
id carrying `?`, `#` or whitespace stops being one segment.

It matters more from C5.1 on. Inside the page these targets go through
`useRouteHandoff`, which matches the pathname against the shell's `pageRoutes`
before deciding anything, and the id is the segment the pattern is reading.

The worktree id was already encoded at both sites; this makes the host id match,
and the new test pins all four targets rather than only the one that moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): render agent session history from the desktop's bundle (OTA phase C, C5.1)

The second page route. `agent-history/[worktreeId].tsx` already shipped in the
bundle with its own chunk, so listing it adds nothing to the download and moves
no route count: the switch is `index.tsx`'s, and the shell still decides, because
a bundle naming a grant this app lacks renders the native panel instead.

Its `.web.tsx` sibling is required for `index.web.tsx`'s reason — the native file
reaches OrcaMobileWebShellView, whose requireNativeViewManager runs at import and
takes the whole bundle down in a browser, since the manifest imports every route.

First route with two dynamic segments, so both are encoded. Grants are `navigate`
and `storage`: a resumed session opens the native session screen, the worktree
list now reaches this screen without leaving the page, and `app/h/_layout.tsx`
reads the app's own sidebar width above every page route.

The panel's router becomes `useRouteHandoff`, which is the seam that tells those
two apart: agent history is a page route and is pushed here, the session screen is
not and goes to the shell.

The three writes a resume makes needed no page-side handling and have none. What
they needed was a test that the descriptor's handling survives the extra hop, so
each is run through the bridge and against the same fake directly and the two
verdicts compared: a refused create raises the host's message, and a lost reply or
a shell disposed mid-flight stays delivery-unknown rather than becoming a failure
a user would retry blindly. No golden covers those three.

The flag census grows its first entry since C1.3, which is what it is for.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the agent-history Back button to the shell handoff

C5.1 wired this button by swapping the panel's `useRouter` for `useRouteHandoff`;
nothing else was needed, because `RouteHandoff` is the router's own shape and the
seam's web sibling decides `back`. So this commit is the test that would have
caught the wiring being absent, not a fix.

Red before the merge, green after, on the same four cases: on `e897e8123a`, where
`back` was still expo-router's own spread member, 3 failed and 1 passed — the one
that passed is the local-pop case, which is the branch C2.2 did not change. After
the merge brought in C2.2's `back`, all 4 pass. The pre-merge run named the notify
by its literal `'navigate-back'` because the contract constant did not exist yet;
it is the same string `BRIDGE_NAVIGATE_BACK_NOTIFY` holds, so the two runs asked
the same question.

Both module substitutions are the builder's own rather than conveniences: the web
bundle resolves `route-handoff` and `client-context` to their `.web` siblings, so
mocking each to its sibling gives this screen the module graph it has inside the
page. The frames are read off the port pair's lane rather than off a spy, and one
case asserts a frame crossed at all before either absence is read as an answer.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): compare the resume's second write, not only its first

Round 1, finding 1. All three `resumeAiVaultSessionInTerminal` cases settled the
create (`ai-vault-resume-launch.ts:158`), so `terminal.send` had never crossed the
bridge and the half of the resume that types the command into the pane was
uncompared. Three cases now drive both writes: a refused send raises the host's
message, an accepted send reporting `accepted: false` in-band says "Terminal input
is locked", and a send the host takes resolves — the last one being the presence
precondition, since a run that failed at the create would give the same shape of
verdict as one that failed at the send.

Reading `requests[1]` straight after settling the create finds nothing on the
bridged leg: the second write is made only once the first settles, so it is two
more lane round trips away. `nthRequest` waits instead, and says how many it saw
when it gives up, so this cannot pass by proving the opposite of what it says.

The locked reply is `{ send: { accepted: false } }`, not `{ accepted: false }`:
the reader is `reply.send?.accepted !== false` (`review-terminal-reply-schema.ts:65`),
and the flat shape resolves rather than throwing. Written the flat way first, both
legs agreed on "(resolved)", which is the comparison doing its job.

Also finding 1's second half: the file docstring claimed every case runs twice and
differences the verdicts, which was false for the dispose case — a fake RPC client
has no door to shut, so there is no native run to compare against. The docstring
now says so and the case carries the same note.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin what encoding cannot save about a dot-segment id

Round 1, finding 2. The route's docstring listed `/ ? #` and whitespace and the
encoding test covered five ids of that kind, which together implied encoding makes
any id safe. It does not: `encodeURIComponent('..')` is `'..'`, so the pathname
reaches `BRIDGE_ROUTE_PATHNAME_PATTERN` intact, fails the lookahead that stops a
climb out of `/h/` (`bridge-caps.ts:68`, read through `bridge-envelope.ts:117`),
and the shell answers with `reportShellFailure` — a failure screen where the route
would otherwise have rendered the native panel it already has.

Pinned, not fixed, and the docstring now says which. `app/h/[hostId]/index.tsx`
builds its pathname identically and has the same hole, so this series fixing one
of two call sites would leave the shape behind and stop describing it. The new
case asserts both halves — the segment survives encoding unchanged, and the
pattern refuses the pathname — so a later change that starts encoding dots fails
here and has to say which screen it wants instead.

Characterisation, so it was green on the first run rather than red: the claim is
about behaviour that already ships, and the value is that the refusal is on record.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): mount the agent-history route in a real browser

Round 1, finding 3. Nothing rendered this route's real module graph anywhere. The
unit tests mock react-native, safe-area, svg, lucide and the icon assets away —
they have to, since react-native is Flow source vitest cannot parse — so a
component in this closure with no web build would have reached a device before it
reached a test. The render check is the only place the graph meets React Native
Web, and this route was not in it.

Two cases. The first mounts the route from the shell double and reads the screen:
"Agent Session History" and the worktree label the params half carried, no fault,
no console error, no CSP refusal, and the URL the page wrote for itself. That also
proves `init.route.params` end to end on a route that has a dynamic segment too,
which §1 of the design claimed and nothing checked.

The second pins the chunk. C5 is the first series whose success path pulls a
second chunk after the first paint, which on iOS goes through WKURLSchemeHandler
under `script-src 'self'`. The chunk is named from the builder's own route map
rather than guessed from the bytes, and asserted absent from what the first route
loaded, so this says the route came over the wire now.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say the real lifetime of the route-handoff refusal set

Round 1, finding 4. The comment claimed one line per reason "for the life of one
client", borrowing `createPageDiagnosticReporter`'s bound. The set is built inside
the `useMemo` keyed on `[client, router]`, so it is per hook instance: in practice
the memo is not recomputed, because `useRouter()` is expo-router's module
singleton and the page holds one client, but every screen calling the hook gets
its own set and a reason can be reported once per screen rather than once per
document.

Says that now, and why it is not tightened: a per-module set would outlive the
page's client, which is the lifetime the rest of these reporters are scoped to,
and there is no document-wide reporter to join without reaching into a contract
file the C2 lane owns.

Records the other half of the finding too, which came back confirmed rather than
changed: `console.warn` is right here. It is the vocabulary `page-bootstrap.ts:35`
already writes in, and a `fault` notify would be wrong twice — the shell drops the
generation on a page fault, and a navigation the page declined is not a failure.

Comment only; no behaviour change, 25 navigation tests unchanged and green.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): wrap every router member that takes a target, not three of five

Round 2, finding 1. `...router` hands through everything this file does not name,
and two of the members it did not name take an href: `navigate` and `prefetch`.
`navigate` to a route outside `pageRoutes` went straight to expo-router and pushed
it into this document — the hole the tri-state exists to close, reopened under a
name nobody had looked at. No call site uses it today, which is why it shipped.

`navigate` is now wrapped exactly as `push` is: which of push-or-collapse it does
is a decision about this document's stack, and a target outside this document has
no such stack.

`prefetch` is decided the other way, explicitly. It is the one target-taker that
must never reach the shell: a prefetch is a background load, `navigate` is the
only thing the shell can be told, so handing one over would open a screen nobody
asked for. A route this document serves is prefetched here, which is what the
per-route chunk split makes worth doing; every other one is dropped without a
line, because a warm-up that did not happen is not a failure to report.

The docstring's "four members that can leave this document" is now five wrapped
members and a rule for which is which.

A list would rot, so the pin is derived: `HrefTakingRouterMember` reads the
parameter tuple of every member of `RouteHandoff` and `WRAPPED_HREF_MEMBERS` is
asserted equal to it in both directions. It reads the tuple rather than testing
assignability because `() => void` is assignable to `(href: RouterHref) => void`,
which would make `back`, `dismissAll` and `reload` target-takers and prove
nothing. Checked both ways: dropping `prefetch` from the list fails the compile
with "Type 'HrefTakingRouterMember' does not satisfy the constraint", and the
union resolves to exactly the five, with `back` and `setParams` outside it.

The pin is in the product module because `mobile/tsconfig.json` excludes tests.
The runtime test asserts each wrapped member is not the router's own function and
that `setParams` still is, so a hook that wrapped everything fails too.

Red first: 4 of the new cases fail against the previous file, 33 pass now.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): say per hook instance in the title too, not per client

Round 2, finding 2. The source comment was corrected in round 1 and this test's
title was not, so the two disagreed about the bound the refusal set actually has:
the set lives in the `useMemo`, so it is per hook instance, and a title claiming
per client is the stronger promise the code does not make.

Title only; the case and its assertions are unchanged.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say what the agent-history render case does not cover

Round 2, finding 3. The docstring claimed the case is where the panel's closure
meets React Native Web, which overstates it. The shell double answers no RPC, so
the session scan fails and the panel paints its "Unable to Load" state: the
session list, its rows, the resume button and the scope tabs never render, and a
render-time gap inside any of them would pass this check.

Now says both halves — import-time evaluation of every module in the closure and
the panel's own chrome are covered, the list subtree is not — and names what
covering the rest would take: a double that answers `aiVault.listSessions`, which
is a different instrument and would put domain behaviour in this file.

Text only. This case moves to its own file on the extracted harness after the
merge with #21592; the corrected text travels with it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): import the handoff module once in its own test

My round-2 fold added `WRAPPED_HREF_MEMBERS` as a second import of
`./route-handoff.web`, which `import(no-duplicates)` fails in the focused-plugins
pass of the changed-code gate. Joined to the existing import below the mocks,
which is where an import of the module under test has to sit in this file.

Found by running the changed-code gate rather than by review: mobile tsc, whole
tree oxlint and the suite were all green with it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): give agent-history its own render file on the extracted harness

The render check gained browser cases from three domain series at once, each
under the `.mjs` cap of 600 counted lines alone and no two of them together: at
39b15e395d the file was 781 raw lines and clean, main's was 786 and clean, and
their merge was 857 raw and 623 counted, which is the CI red on #21596. C1.10
extracted the harness so a domain gets a file instead. This is C5's, and the
render check is back to 639 raw lines and clean.

Five cases. The two that moved — the route mounts and paints, and its chunk is
fetched on navigation — plus three new ones.

Back, twice. With `navigate` granted the page's Back control posts exactly one
`navigate-back` notify and the page does not move; with the grant withheld the
same tap reaches the same handler and posts nothing. The pair is the point: the
document holds the single history entry the entry wrote with `replaceState`, so a
Back this page served itself would also have gone nowhere and looked identical.
This is the first proof of that handoff in a browser rather than against a mocked
router.

And a row. The harness's new `replies` lets the double answer named methods, so
the panel now renders a real session instead of its "Unable to Load" state, which
is the render-time gap the round-2 docstring conceded. Assertions are on the row's
own text and message count, plus the absence of both silent states — the scan
failing, and a session out of scope.

Replies lifted from the corpus, and one of them needed two scenarios. The session
and worktree lists are `aivault-history-screen-listed`'s. Its `status.get` is a
capability list alone, and the first run painted "Update Orca on your computer":
`HostProtocolGate` above every host route reads the same method for fields that
scenario never scripts. The status reply merges those from
`transport-host-status-gates-ready`, and the comment says why two.

`wt-history` is load-bearing, not incidental. The panel opens on the `workspace`
scope and filters by paths from the worktree list, so on any other worktree these
same replies paint "No agent sessions" — green, and proving nothing.

Registered in the `mobile_web_app` job beside the drawer check, which is the job
that makes a missing mobile install fail rather than skip.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): encode the host id at every href the host page builds

Pullfrog on #21596. My earlier commit fixed the two hrefs in the row's navigation
sheet and stopped there; five more sites in the same page interpolate the decoded
id raw — Accounts and Tasks in both header layouts
(`host-screen-header.tsx:188,204,307,318`) and the session target
`openWorktreeSession` builds (`use-host-worktree-actions.ts:192`).

Same C1.2 class. The persisted host store admits any non-empty id and both
`useLocalSearchParams` and the store answer it decoded, so one carrying `/`, `?`,
`#` or whitespace stops being the single segment `matchesRoutePattern` reads.
Inside the page that decides where a tap goes, because the handoff matches the
pathname against the shell's `pageRoutes` before choosing this document or the
native stack.

A census rather than five more assertions: the failure is a habit, not a bug —
each of these was written by copying the one beside it, and the seventh will be
too. It counts `/h/${...}` interpolations across the host page's four source
files and requires `encodeURIComponent` at each, with a presence check so it
cannot pass on an empty list.

Two sites are exempt and stay raw: `use-host-worktree-actions.ts:171` and
`app/h/_layout.tsx:100` compare against a pathname the router answers rather than
building a link, so encoding them would change what a comparison matches instead
of what a tap opens. The exemption is subtracted by count rather than matched
away, so a file that lost its comparison and gained a raw target does not come
out even.

ONE BEHAVIOURAL EDGE, named rather than fixed. `navigateFromHostList` short
-circuits when `pathname` equals the target minus its query. That comparison now
has an encoded target on one side and whatever `usePathname()` answers on the
other, so for a host id that needs encoding the short-circuit stops firing and a
tap on the screen you are already on re-navigates instead of doing nothing. It is
a redundant navigation, not a wrong one, and the guard at :171 is unaffected
because it compares against the same raw form it always did. Left alone because
fixing it means deciding what `usePathname()` returns for an encoded segment,
which is a question worth its own change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): guard the optional host id the session target encodes

The commit before this one did not typecheck: `useHostWorktreeActions` takes
`hostId` as `string | undefined`, and `encodeURIComponent` does not. I committed
on a green test run without waiting for `tsc`, which is my error and the reason
this is a second commit rather than an amend — the lane forbids rewriting a
commit that exists.

`?? ''` rather than a cast or a non-null assertion. An absent id then builds
`/h//session/...`, an empty segment the shell's own route rule refuses, instead
of the string "undefined", which that rule would accept as a host genuinely named
undefined. Every other member of this hook already guards the same field.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the agent-history route native when the bridge would refuse its id

CodeRabbit on #21596. The persisted host store admits any non-empty id, so `.` or
`..` reaches this route, survives `encodeURIComponent` unchanged, and fails the
bridge's own segment rule. The route handed it over anyway: `bridge-host.ts`
parses the route against `BridgeInitRouteSchema`, drops it to null when it fails,
and the page answers an `init` naming no screen with "Update Orca to open this
workspace". A failure screen, in place of the native panel sitting right behind
this switch.

The route asks the schema first now and stays native when the answer is no, which
is where every route starts. Mirrors C3.1's call for the files routes
(`69e618e19a`), including its reason for using the schema rather than a copy of
its bounds: two spellings of one rule drift, and the half that matters is the
half the page reads.

The pin moves with it. It characterised the refusal before — asserting the
pathname was built and that the pattern rejected it — and now asserts the native
render, for a dot host id and for a dot worktree id, which is the other segment
and was never covered.

`app/h/[hostId]/index.tsx` has the same hole and is not fixed here, as asked: it
builds its pathname the same way and hands it over unchecked. When C3.1 is also
on main the two guards and `mobile-file-shell-route.ts` belong in one module
beside the schema, rather than a third spelling of a one-line call.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): forward navigation options through the wrapped router members

CodeRabbit (major) on #21596. expo-router's `push`, `replace`, `navigate` and
`dismissTo` are `(href, options?)`, and the wrappers took the href alone. A local
push asking for `{ withAnchor: false }` reached the router without it, so inside
the page the router did something other than what the caller wrote — silently,
because dropping an optional argument is not a type error.

Each wrapper forwards both on its local branch now. Nothing in this tree passes
options today, which is why it went unnoticed and exactly why it needed pinning:
the first caller to pass one would have had it dropped without a word.

Options do not cross to the shell, and the docstring says so rather than leaving
it to be discovered. The `navigate` notify carries an href and nothing else, so a
target handed over is opened by the native stack on that stack's own terms. That
is the right shape — the options describe a push inside a document the shell's
target is not in — but it is a loss, and a loss worth naming.

Four existing assertions moved from `toHaveBeenCalledWith(href)` to
`(href, undefined)`. That is what the router now receives when a caller passes
none, and expo-router reads an undefined second argument as absent; the comment
above them says so, so the next reader does not take it for a bug.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): count the wrapped members the way the returned object does

Pullfrog on #21596. The header still described the set as it stood before
`860577cc30`: "the four members that can leave this document", "the three that
carry a target", "the other three". There are six wrapped members now and five
carry a target, so every count in the paragraph was one or two short and a reader
checking the object against the prose would have found neither explained.

Now says six wrapped, five target-takers named and pinned by
`WRAPPED_HREF_MEMBERS`, four decided by the shell's route list, `prefetch` the
fifth and decided differently for a reason the member's own comment gives, and
`back` the sixth carrying no target at all.

Comment only; 36 navigation tests unchanged and green.

Jinwoo Hong b7c06900e2 fix(mobile): give reanimated mapper hooks the inputs esbuild never writes (OTA phase C, C1.10) (#21592)
* refactor(mobile-web): extract the page render harness

The shell double, the CSP/bridge constant readers and the bundle server were
private to mobile-web-app-render.test.mjs, so a second check against the same
page had no way to reach them. Moved as-is into a module both can import; the
double also gained a `replies` map so a check can answer one method and leave
the refusal in place for everything else.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give reanimated mapper hooks a dependency array

The bottom drawer never slid onto the screen in the web shell page: `progress`
animated to 1 and `withTiming` reported finished, but the sheet kept the
translateY of the animation's first frame and sat one viewport below the fold,
with its invisible backdrop swallowing the next touch.

Cause, bisected in the browser: `useAnimatedStyle` reads its mapper inputs from
`updater.__closure` (hook/useAnimatedStyle.js), which only Reanimated's Babel
plugin writes. The page is bundled by esbuild, which runs no Babel, so
`__closure` is undefined; with no dependency array either, `inputs` is empty and
`startMapper` registers a mapper that listens to no shared value. It runs once
and never again. Reanimated does throw for exactly this, but behind `__DEV__`,
which the bundle builds out, so the page reports nothing. The rAF loop stopping
after one write is the observable end of it.

Not a WebKit fault. Headless Chromium parks the sheet the same way
(translateY(843) vs WebKit's translateY(841)), so the earlier
JavaScriptCore-vs-V8 reading does not hold, and the pin added here runs on both
engines rather than on Chromium alone. WebKit is downloaded in the
mobile_web_app job for it.

Every mapper-backed call site takes the same array, not just the drawer's:
RightDrawer and DragReorderList are the same defect on the same bundler.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): census the reanimated hooks that need a dependency array

The drawer pin covers MountedBottomDrawer only, and the failure mode is silent:
a new `useAnimatedStyle`, `useAnimatedProps` or `useDerivedValue` without an
array animates once on the phone's native build and freezes in the web page,
with no error on either. Parsed rather than grepped so a call spanning lines,
or one whose second argument is not an array, is still seen.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile-web): state motion-on as the drawer pin's precondition

Under `prefers-reduced-motion: reduce` Reanimated finishes `withTiming` in one
frame, so a mapper that only ever runs once still writes the final translateY
and the pin goes green on the broken build. Measured: the unfixed bundle under
reduced motion lands at translateY(0) with the sheet on screen in both engines,
which is also what the Android emulator does with animator scale off — the same
single write, not a healthy animation. The context now says no-preference and
the page is asked to confirm it.

* test(mobile): census useAnimatedReaction, whose deps are its third argument

Same fallback as the other three (hook/useAnimatedReaction.js:26-34), so the
same silent freeze applies. Its shape is not the same: the array is argument
three, behind `prepare` and `react`, and both callbacks run inside the one
mapper it starts, so both count as updaters. Indexing it like the others would
have read the `react` callback as the array. No call site today; this is the
gate for the first one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): require the dependency array to list every value the updater reads

An array proves a call was written, not that the mapper listens to everything
it reads. On web `inputs` becomes exactly that array
(hook/useAnimatedStyle.js:338-341), so a value read but not listed is a value
the mapper never hears about: the updater stops re-running when only that one
changes. Same freeze as no array at all, in one prop rather than all of them.

Reads only. The first fixture caught this check counting `opacity.value = v` as
a read, which it is not -- a written value is an output, and demanding it in
the array would be noise at every `useAnimatedReaction`. Assignment targets and
increments are excluded; a value both read and written is still required.

Verified against the tree by dropping `translateY` from the bottom drawer's
array, which the census names at mounted-bottom-drawer.tsx:286.

* test(mobile): resolve the hook through the file's imports, not by spelling

Matching the callee's text both missed and invented. `useAnimatedStyle as useAS`
and `Reanimated.useAnimatedStyle` are the same hook wearing another name and
went unchecked; a local helper that happens to be called `useDerivedValue` is
not this hook and would have been flagged. Each local name is now resolved
through the file's imports from `react-native-reanimated`, named, aliased or
namespace member.

A second argument that is not a literal array now counts as present rather than
missing: the hook only needs an array to exist, and this file cannot see what a
hoisted `const deps = [...]` holds, so completeness covers literal arrays only.

Resolution can fail closed, which would read exactly like a clean tree, so the
census now asserts it saw the calls before asserting none are missing. Checked
against the tree by dropping `translateX` from RightDrawer's array, which it
names at RightDrawer.tsx:156.

* test(mobile-web): select the drawer sheet by name, not by its corner radius

The pin walked up from the handle to the first ancestor with a 16px top radius,
so it found the sheet through a styling token. Change that radius and the pin
reports `sheet: false` -- a red naming the selector rather than the animation it
exists to watch, on a change that broke nothing.

The sheet now says what it is. `testID` on the RN side renders as `data-testid`
on web (react-native-web createDOMProps/index.js:832), which is the one line of
product change this needs.

Re-verified after retargeting: still red on both engines with the dependency
arrays removed (translateY 843.271 chromium, 841.447 webkit), green with them.

* docs(mobile-web): say why the motion option must precede navigation

Reviewer follow-up on the reduced-motion guard. The context option and the
`goto` order are both load-bearing, and nothing in the file said so: Reanimated
reads `matchMedia('(prefers-reduced-motion: reduce)')` once into a module-level
const at import (ReducedMotion.js:8-10), so a `page.emulateMedia()` after
navigation would leave the assertion passing over a value already latched true.
Comment only.

* test(mobile-web): name the drawer pin's precondition instead of asserting past it

CI's Linux WebKit failed this pin at `matrix(1, 0, 0, 1, 0, 844)` -- exactly the
viewport, the mount-time value, not a first-frame 843.x. Nothing animated there,
so the pin was reporting a parked sheet without being able to say whether the
mapper was subscribed. Two different faults, one message.

`requestAnimationFrame` separates them and sheet writes do not. `withTiming`
schedules a frame per step (valueSetter.js) whether or not a mapper listens, so
frames across the window mean the shared value moved; the assertion now names
that. Counting sheet writes as the precondition inverts the diagnosis: measured
on the broken build, "written more than once" fires first and calls the defect
this pin exists to catch an engine that does not animate.

Sheet writes stay, as a second statement of the subject and as context in the
transform failure, which now reads "1 style write(s) on the sheet across 30
frame(s)" on the broken build.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile-web): wait for the drawer to arrive, not for a clock

The pin paused a fixed 1s after the sheet opened and then read the transform,
which makes it a race on a loaded runner: a healthy engine that is merely slow
reads as parked, and the red names the transform rather than the wait. It now
waits for the settled transform, times out at 15s, and asserts on whatever it
found either way, so a genuinely parked sheet gives the same red with the
timing assumption removed. On the broken build that red now reads "1 style
write(s) on the sheet across 3635 frame(s)", which says the fault in one line.

Aimed at CI's Linux WebKit red rather than proven against it: eight container
runs on the Playwright Linux image never reproduced that failure. See the
report for what the container did and did not show.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile-web): stop asserting on the sheet's style-write count

The count cannot carry an assertion in either direction. Measured under
`--cpus=0.35` in Playwright's Linux image, a healthy page starved of frames
reaches translateY(0) in a single write, because `withTiming` covers the whole
180ms in one step when one step is all the frames it gets. "Written more than
once" would have redded that page, which is a CI runner under load -- the exact
situation this pin keeps meeting.

So the transform is the only subject, `requestAnimationFrame` during the window
is the only precondition, and the write count is context in the failure text.

Also worth recording against the CI log: exactly `matrix(1, 0, 0, 1, 0, 844)`
is reproducible here on the broken build, as the single mapper run landing at
progress 0. It is the mapper's signature as much as a dead engine's, so it does
not on its own say which failed -- the frame and write counts now printed
beside it are what separate them.

* test(mobile): count a value read under a unary operator as a read

`isWriteTarget` took any prefix-unary parent for a write, so `!hidden.value`,
`-offset.value`, `+x.value` and `~x.value` were dropped from the reads the
dependency array has to list. A style that gates on `!hidden.value` would have
passed the census while its mapper never listened to `hidden` -- the exact
freeze this file exists to catch, hidden by the check meant to catch it.

Only `++` and `--` mutate, so the prefix branch is narrowed to those two.
Postfix needs no narrowing: `++` and `--` are the whole set there.

Red-first with a negation fixture and a unary-minus fixture; the increment
fixture holds the other side, that a value only incremented is still not
required. Found by a review bot on #21592.

Jinwoo Hong 57fdf68ab3 feat(mobile): let the page hand a link to the device through the shell (OTA phase C, C2.3) (#21597)
* feat(mobile): answer externalLink on the shell side of the bridge (OTA phase C, C2.3)

A page has no way to open a URL outside itself: `Linking.openURL` is the
app's, and inside the shell the page is a document that cannot reach it. Adds
`notify { name: 'externalLink', url }` and a new grant name of its own in
`MOBILE_WEB_SHELL_GRANTS`, rather than a verb of `navigate` — `navigate`
opens a screen this app carries, this hands a URL to whatever the device
opens it with, and a shell implementing one and not the other is a real shell
the route policy has to be able to describe.

`https:`, `http:` and `mailto:` only, and broad inside that: any host, any
path, because a grant that named GitHub would grow a row per provider. The
rule is parsed rather than prefix-matched, since a scheme is what a URL
parser says it is and `startsWith('https:')` reads one out of
`javascript:alert("https://x")`. It is enforced at the frame as well as at
the page's call site, so a page that skipped its own check still cannot reach
the device handler. Bounded by the route href cap, per the ruling.

`BRIDGE_PROTOCOL_VERSION` is not bumped. Inert until a consumer exists: no
call site and no barrel is touched here.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): plumb externalLink through the bridge hook probe (OTA phase C, C2.3)

The hook's own suite builds its caller options inline, so the new required
option made it stop typechecking. `tsc -p tsconfig.json` excludes test files;
only the tests-typecheck ratchet saw it.

Adds the case that goes with it: a URL the page hands over reaches the
caller that can leave the app, and nothing reaches the navigate path.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): let the page post an externalLink over the bridge (OTA phase C, C2.3)

`notifyExternalLink(url)` on the page client, gated on the `externalLink`
grant and on the same scheme rule the frame enforces.

Checked twice on purpose. Nothing crosses back for a notify, so the boolean
is the only answer a tap gets: a page that posted a URL the shell's reader
then dropped would report "opened" into a frame nobody acted on, which is
precisely the dead tap the grant exists to rule out.

False before `init`, false after `close`, and never a throw — the callers are
tap handlers with no catch around them.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): add the external-link seam the tasks call sites will use (OTA phase C, C2.3)

One module with a `.web.ts` sibling, which is the shape every platform gap in
this bundle already takes. Native is `Linking.openURL` with the rejection
swallowed, because every caller is a tap handler and `openURL` rejects for a
URL no installed app claims. Web posts the `externalLink` notify after the
same scheme check the frame enforces, names its refusals and throws nothing.

The opener is published by the entry rather than read from context, for the
reason `publishPageStorage` is: the callers are plain functions in render
trees the provider does not wrap. A document that published none refuses
every URL, which is the right answer for a page with no shell.

Registered in `web-overrides.json`: inside the shell's WebView, react-native
-web's `Linking.openURL` opens the URL in that WebView and replaces the page
rather than handing it to the system browser.

No call site and no barrel is touched. The consumer PR swaps them onto this.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state the real reason the page cannot open its own links (OTA phase C, C2.3)

The override reason claimed react-native-web's `Linking.openURL` opens the
URL in the shell's WebView and replaces the page. It does not. Read from
react-native-web 0.21.2: `openURL` calls
`window.open(url, '_blank', 'noopener')` and resolves whether or not anything
opened; only a `tel:` URL assigns `window.location`, and none of the three
allowed schemes is one.

The true failure is the worse one and the better argument for the verb. Both
shells refuse `window.open` outright, measured in their own sources: iOS sets
`javaScriptCanOpenWindowsAutomatically = false` and returns nil from
`WKUIDelegate`'s `createWebViewWith`; Android sets the same flag false, calls
`setSupportMultipleWindows(false)` and returns false from `onCreateWindow`.
So nothing opens, `openURL` resolves anyway, and the native path reports
success into a tap that did nothing — precisely the dead tap the grant exists
to rule out.

The seam's own comment now says the same, so the two files cannot drift.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): report a URL the phone could not open (OTA phase C, C2.3)

The shell swallowed `Linking.openURL`'s rejection. Nothing crosses back to
the page for a notify, so an open that failed — a `mailto:` on a phone with
no mail account — was silent on both sides. That is the one dead tap this
verb does not rule out, and it was the only one with no record at all.

Warned with the URL and the error, in the shape the two neighbouring reports
in this screen use, and still not rethrown: this runs on the native frame
handler. The contract now asks for the report rather than only for the
absence of a throw.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): forward the URL the parser read, not the string the page sent (OTA phase C, C2.3)

The scheme check reads the protocol through the WHATWG parser, which strips
tab, LF and CR from anywhere in a URL and trims leading C0 and space before
the scheme is visible. So `ht\ntps://example.com`, `https://example.com/a\r\n`,
`  https://example.com/a  ` and `https:example.com` all passed the check, and
both sides then forwarded the original string. Not a scheme escape — the
parser had already decided the scheme — but the device handler was given a
URL the check never looked at, which is a dead tap through an allowed URL.

`readBridgeExternalLinkUrl` answers the parsed href, and the page posts it
and the host forwards it. Normalizing rather than comparing, because
`https://example.com` differs from its own href by a path slash: refusing
what differs from its normalization would refuse an ordinary URL.

The cap now applies to the normalized form as well as the raw string, since
percent-encoding expands and a string inside the cap can leave it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): exercise the seam's default opener instead of a published one (OTA phase C, C2.3)

The case named for a document that published no opener published one first,
and `post` is module state every earlier case had already set, so the default
at the top of the module was never the thing under test. The only assertion
was `not.toThrow()`, which passes against any implementation.

`vi.resetModules()` and a fresh import, and the refusal reason is asserted.
Confirmed to discriminate: flipping the default to `() => true` turns this
case red and leaves the other three green.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): build the openURL rejection per call, not at mock setup

The case added for a failed open used
`mockReturnValue(Promise.reject(failure))`, which builds the rejected promise
at setup time. Nothing attaches a handler until the notify frame arrives
several awaits later, so the suite reported an unhandled rejection and exited
1 with every test passing — a red run that reads as green in the counts
alone.

A fresh rejection per call closes the window, and `openUrl` is reset between
cases so the mock cannot leak into one that does not expect it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): guard the openURL failure that escapes a tap handler (OTA phase C, C2.3)

`Linking.openURL` validates before it returns anything: `_validateURL` is an
`invariant` that throws for an empty string (react-native 0.83.10,
`Libraries/Linking/Linking.js:117-123`). So the seam's `.catch` was attached
to a promise that, in that case, never existed, and the throw went straight
through a tap handler — contradicting the module's own claim to be safe in
one.

Both failure modes are now caught and reported, and neither is rethrown. The
test double validates the way the real module does, because a mock that only
rejects cannot reproduce the failure that escapes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): collapse the duplicate openURL wrapper onto the seam (OTA phase C, C2.3)

`mobile-pr-url.ts` was the seam's native body already, byte for byte, written
before it. It now re-exports the seam under its own name, so the empty-URL
guard and the failure report reach its four callers too.

Nothing changes natively: the seam's native form is what those callers were
running. On the web they would now post the notify instead, which is the
behaviour they should have had; it is unreachable today, since none of them
is in a page route's closure.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): read externalLink end to end over the port pair (OTA phase C, C2.3)

The pair harness grew `externalLinks` and nothing read it. This is the
`navigate` twin's shape, over the six normalization inputs: what the page put
on the wire and what the shell forwarded are the same strings, read back off
the frames rather than recomputed, and nothing reaches the shell's client.

Two halves on purpose. The page normalizes before it posts, so over the
client the host only ever receives an already-normalized URL and forwarding
it raw would pass — the frame injected straight into the host at the end is
what holds the host to the rule on its own. Confirmed to discriminate:
reverting the host to forward `message.url` turns that assertion red.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* style(mobile): match the neighbours on three small inconsistencies (OTA phase C, C2.3)

Three of a kind, none behavioural:

- the notify guard's docstring had a 109-character line; reflowed
- the shell's could-not-open warning passed three arguments where the three
  other reports in that screen pass two; it now passes `{ url, error }`
- the native seam's suite built its rejection with `mockReturnValue`, which
  is the shape `52191bab02` removed elsewhere; it now builds one per call,
  through the same double that validates the way the real module does

Jinwoo Hong 1ef947394b feat(mobile): hand the page's dead Back button to the shell (OTA phase C, C2.2) (#21582)
* feat(mobile): answer navigate-back on the shell side of the bridge (OTA phase C, C2.2)

A page served at `/` holds the one history entry its entry wrote with
`replaceState`, so `history.back()` goes nowhere and a page Back button is
dead. The only stack with somewhere to go is the native one the shell pushed
the page onto.

Adds `notify { name: 'navigate-back' }` to the closed client union, gated on
the existing `navigate` grant rather than a name of its own: an app that can
open a screen can close one, and a new grant name would leave every route
declaring it native on every shell already shipped. `MOBILE_WEB_SHELL_GRANTS`
is unchanged and `BRIDGE_PROTOCOL_VERSION` is not bumped.

`bridgeNotifyRefusal` grows a name-to-grant table, since this is the first
notify whose name is not its grant's. The shell screen pops its own stack and
answers false when there is nothing left, which the host logs as
`navigate-back-refused` — nothing crosses back to the page either way, so
silence there is indistinguishable from a Back button that worked.

Inert until a consumer exists: no page posts the name yet.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): hand the page's dead Back button to the shell (OTA phase C, C2.2)

`useRouteHandoff` wrapped `push`, `replace` and `dismissTo` and left `back`
as expo-router's own, which inside the page pops a history of one and does
nothing. It now pops locally when the document grew a stack of its own, and
otherwise posts `navigate-back` for the shell to pop the native stack.

This is what makes the Tasks header's `onPress={() => router.back()}`
(`src/tasks/mobile-tasks-screen-chrome.tsx`) work once the C2.1 consumer
routes that screen's router through this seam; the barrel still reaches
expo-router directly, so nothing calls this yet.

A shell that granted no `navigate` falls through to the local router rather
than throwing out of a tap handler. A shell that granted `navigate` but is
too old to know the verb refuses the frame as `unrecognised-message` and
logs it; neither is distinguishable from the page, and the fallback goes
nowhere in both — which is exactly where Back already went.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): count back among the members that leave the page document

The header said three wrapped members driven by one answer. `back` is a
fourth, and it is not driven by that answer: it carries no target, so the
document's own stack decides it rather than the shell's route list.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): complete the bridge hook probe in its two local literals

`Probe` grew `backPops`, and two cases build the object inline rather than
through `mount`. `tsc -p tsconfig.json` excludes test files, so only the
tests-typecheck ratchet saw it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(config): measure the stack the page Back button rests on (OTA phase C, C2.2)

`useRouteHandoff().back()` asks expo-router's `canGoBack()` whether this
document can serve a back itself, and that answer is React Navigation's, so
no unit test settles it. The render check now measures it in the browser it
actually runs in.

Read through `router.back()` on `/h/[hostId]/edit`, a real route of this tree
whose chevron is expo-router's own back, because the page exposes no handle
to call `canGoBack()` on and a global added for a test would ship forever.

Measured: the router has nowhere to go on the document the shell opens, and a
location change does not give it one either. So the handoff's `canGoBack()`
gate answers false for everything the shell or the browser can do to the
page, and its local branch belongs to a push the page makes through the
handoff itself.

The shell double now records every notify the page posts and takes the grant
list as a parameter, so a control that handed something to the shell can be
told from one that did nothing. The first case asserts a real tap crossing
the bridge, which is what makes the two absences after it evidence.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): refuse a second stack pop while the first is still queued (OTA phase C, C2.2)

`canGoBack()` and `back()` disagree about time. The first reads the committed
navigation state; the second only adds `GO_BACK` to expo-router's
`routingQueue`, which `useImperativeApiEmitter` drains from an effect. Two
`navigate-back` frames delivered in one native batch therefore both read the
stack the first pop has not left yet, both queue, and a three-deep stack
unwinds past the screen the page was opened over. The host forwards every
notify it is granted, so nothing upstream coalesced them.

`useShellStackPop` owns the pop and latches it. The latch clears on the
committed route rather than on a timer, because that commit is the first
moment `canGoBack()` answers for the stack the pop actually left; a pop that
takes this screen off the stack unmounts it and takes the ref with it.

`onNavigateBack` now answers `popped` / `nothing-to-pop` / `pop-pending` so
the `navigate-back-refused` diagnostic is true for the frame it names, and
the log dedupes per reason rather than burying the second behind the first.

Driven against expo-router 55.0.18's own `global-state/routing.js`,
evaluated verbatim with only its externals stubbed: a mock of `canGoBack`
is what hid this.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make the notify grant table total over the union (OTA phase C, C2.2)

The table was `Record<string, string | undefined>` indexed with a plain
string, so a notify name with no row returned undefined, read as ungated,
and the host acted on a frame it had never granted. Adding a member to the
envelope's notify union raised no error anywhere — the hole was silent.

Keyed on `Extract<BridgeClientMessage, { type: 'notify' }>['name']` with
`string | null` values, an omitted row is now a TS2741 on the table itself,
and `bridgeNotifyRefusal` cannot be asked about a name the table has no row
for.

Adds the `navigate` and `storage` rows, which were missing: the host was
enforcing the navigate grant for `navigate-back` but not for `navigate`.
Both are inert while every page is offered every grant, and load-bearing the
moment a grant is per-route.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(config): assert no page errors in the browser case that drives popstate (OTA phase C, C2.2)

The case that dispatches a synthetic `popstate` read its answer as "the page
did not move", and a throw under the page's fault boundary leaves the page
exactly there. Without the errors assertion the other two cases carry, that
absence was not evidence of what it claimed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): read the routing module's members instead of asserting them

The casting gate refuses the two assertions the loader used, and it is
right: a stub that stopped covering an import would have left the members
undefined and the test would have driven a half-evaluated module. Destructure
and check instead, so that case says so.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): name the two pops the stack latch never hears about (OTA phase C, C2.2)

The comment read as if the clear were exhaustive. It is not: a pop landing on
an equal pathname does not transition `usePathname`, and a `GO_BACK` the queue
discards commits no route at all — `routingQueue.run` shifts every action off
the queue whether or not `ref.current` is set.

Kept the pathname clear rather than moving to the navigator's `state` event.
The event would cover the first stick: `@react-navigation/core` 7.17.2 emits
`state` from an effect keyed on the navigator state object, and every pop
replaces it. It would not cover the second, which changes no state. And the
emitter is the navigator, not the routing module this hook is written and
tested against, so the switch cannot be earned by a test here the way the
queue behaviour was — it would rest on a mock of the signal under test.

Both sticks are bounded instead, in the commit that makes the latch one per
stack: the holder releases on unmount, so a stick lasts at most as long as the
screen that took it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold one pending stack pop per stack, not per screen (OTA phase C, C2.2)

`MobileWebShellScreen` mounts at both `app/h/[hostId]/index.tsx` and
`app/h/[hostId]/web.tsx`, and `/h/a/web` is deep-linkable over `/h/a`, so two
shells can be mounted over one native stack. A latch per screen left each of
them holding its own, and two frames from two pages still unwound two screens.

The latch is module-scoped and carries which screen took it, so a shell whose
own route commits cannot release a pop another shell is still waiting on. The
holder also releases on unmount, which is what bounds the two pops the
pathname clear never hears about: a latch nobody is left to release would
outlive the stack it guards and leave Back dead for the session.

Both screen suites now unmount their trees between cases, because a tree that
is only dropped is a screen still holding whatever pop it took.

* refactor(mobile): drop the gated-notify name list nothing reads (OTA phase C, C2.2)

`BRIDGE_GRANT_GATED_NOTIFY_NAMES` existed so a caller could ask which names
ride a grant. Once the table became total over the notify union, the table
itself answers that and the only readers left were the two assertions that
read the list for its own sake.

Deleted with them. The behaviour they stood next to is kept: the protocol's
own names are still asserted ungated through `bridgeNotifyRefusal`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say what the routing-module guard actually catches (OTA phase C, C2.2)

The comment claimed the guard catches a stub that stopped covering an import.
It does not: evaluating the module with every stub dropped still defines all
three exports, because the module assigns them whatever its imports resolved
to, and the failure surfaces later as `TypeError: Cannot read properties of
undefined (reading 'navigationRef')`.

What the guard does catch is an expo-router upgrade that renames or removes
one of the three members this test drives.

* test(mobile): keep the second shell mounted across the holder's removal (OTA phase C, C2.2)

The harness swapped the tree's root element between a single shell, a
fragment of two, and a single shell again. Each swap remounts everything
under it, so the callbacks the cases held belonged to unmounted hooks. One of
those could still take the module-scoped latch, and the instance that took it
was already gone, so nothing was left to release it — the last case in the
file leaked the latch into whatever ran next.

The root is now one component with a slot per shell, so removing the holder
leaves the second shell's instance alone, and every pop is taken through a
callback re-read at call time.

`afterEach` now asserts the latch is clear by mounting a screen after every
other one is gone and requiring it to pop. Without it this leak was invisible:
it surfaces only in a following case, and the case that caused it was last.

Jinwoo Hong 889c2b562f feat(mobile): say why a host is unreachable instead of "Connecting via Relay…" (#21566)
* feat(mobile): say why a host is unreachable instead of "Connecting via Relay…"

The home-screen host row and host header showed "Connecting via Relay…" for
as long as the desktop stayed unreachable, even when every relay dial had
ended with the cell's 4404 host-offline close. A user's diagnostics export
showed 25 such dials over 25 hours behind that label, and the diagnostics
report itself said "No single failure cause" because relay dial failures
were not recognised and every app resume emptied the evidence window.

Relay close codes now map to a closed RelayHostReachability verdict
(signed-out, host-offline, credential-refused, unreachable), latched after
two consecutive identical dial failures and cleared only by an authenticated
session. The existing signed-out close reason becomes a member of the same
verdict instead of a parallel boolean. classifyConnection renders each
verdict as a label plus a detail line ("Host 1 is offline" / "Check it's
awake, Orca is running, and you're signed in").

Relay dial failures carry their close code as a structured field on the
connection log entry, so the diagnostics analysis names the cause without
parsing error text, and an app resume no longer hides the last failure: it
is reported with a "Before the app last resumed" qualifier and is never a
sendable incident.

* test(mobile): re-record RPC goldens at the new baseline

Only header lines change: the baseline pin on every golden and the
adapterSha256 on the twelve goldens whose mount adapters gained the
getRelayHostReachability context method. No checkpoint moved, which also
shows the commits between the old and new baseline changed no observed
RPC behaviour.

* fix(mobile): tell a refused relay credential to re-pair, not to find the same network

A direct session also rotates the credential, but telling the user to
connect on the same network once explains the mechanism instead of giving
an action, and re-pairing is the one remedy that works from anywhere.

* fix(mobile): let the newest relay failure win the diagnosis, and name the real stale boundary

Relay-path evidence still outranks a newer direct timeout, but among relay
failures the newest now wins: an older 4404 verdict no longer hides a newer
session close (which was also the sendable incident) or a director refusal.
The stale prefix names a network change when that, not a resume, was the
boundary.

Jinwoo Hong 0817476b2c fix(mobile): follow-ups from the C1 stack review, one commit per finding (OTA phase C, C1.8) (#21570)
* fix(mobile): encode the host id the native list hands the shell

`web.tsx` encodes the host id into the pathname it opens the shell on; the
worktree-list route beside it still interpolated it raw. `useLocalSearchParams`
answers the decoded value, so a host id carrying `?`, `#` or whitespace builds a
pathname that is no longer one segment.

That shape is not refused where it is built. `matchesRoutePattern` splits on `/`
alone, so `/h/a?b` reads as the single segment `/h/[hostId]` names and the
session starts; the bridge's pathname rule is what refuses it, one `init` later,
and the shell turns that refusal into `document-load-failed`. The route ends on
a failure screen instead of the native list it already has and was about to
render anyway.

The fix sits at the interpolation rather than at the pattern or the bridge,
because the other two are right: the pathname rule is what a path may be, and
the page decodes the segment back when it matches `[hostId]`, so the screen it
opens is the same one. A deep link is the way such an id arrives, which is what
the sibling route's own test already establishes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): end a route segment at the query, not only at a slash

The dot-segment lookahead both route patterns are built from treated `/` and
end-of-string as the only things that close a segment. An href may carry a
query, so the last segment can also be closed by `?`, and there the lookahead
never fired: `/h/..?x`, `/h/%2e%2e?x` and `/h/.?x` all passed
`BRIDGE_ROUTE_HREF_PATTERN` while their slash-terminated spellings were refused.

The sink is `router.push`, and a URL parser resolves `/h/..?x` to `/?x` exactly
as it resolves `/h/../x` to `/x`. That is the climb out of the `/h/` prefix the
rule exists to stop, reached through the one punctuation the rule did not treat
as a boundary.

Fixed in `BRIDGE_ROUTE_SEGMENT_SOURCE`, which is the single place the segment
rule is written and the reason the two patterns cannot drift apart. The pathname
pattern is unaffected: a `?` fails its character class wherever it appears, so
widening the boundary cannot let anything new through there. The existing
segment-rule block gains the query-terminated spellings beside the ones it
already pins.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say which notifies actually reach the mount-order throw

The header said a call before `init` is a mount-order bug and throws, and named
`notifyPageFault` as the one exception. Two more never reach that throw: a grant
is read off the session, so before `init` there is no grant either, and the `&&`
in `navigate` and `storage` short-circuits before `post` can require one.

The code is right and the comment was not, so the comment is what changed. False
is already these two members' refusal answer — it is what they give a shell that
withheld the grant — and both callers handle it. `useRouteHandoff` calls
`notifyNavigate` uncaught inside `push` and falls back to routing inside the
page, so making this path throw would turn an early tap into an unhandled error
in a handler nobody wrapped, which is the same reason the close path answers
inertly rather than throwing.

Pinned rather than left to the prose: the two gated notifies answer false and
post nothing before `init`, the two ungated ones still throw, and the gated ones
post once the shell has granted them. Not a red-first test — there is no defect
here to reproduce — but the contract now has a test holding it in place.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): re-arm the shell session the route rebuilt, not only the host

Two effects share one session. The first rebuilds it from `hostId` and
`routePathname`; the second is the only thing that ever tells the reducer what
the gates say, and it listed the host alone. A fresh session starts in
`checking` and moves on nothing but `gates-changed`, so a route that changed
under an unchanged host and unchanged gates threw the old session away and left
the new one with no effect to run and no verdict to wait for.

`routePathname` joins the gates effect's dependency list, beside the `hostId`
that is already there for the same reason: both are what rebuild the session
above, so both have to re-arm it. Fixing it in the dependency list rather than
by having the reducer restart on a repeat verdict keeps the reducer's rule
intact — a repeat verdict genuinely is nothing new — and keeps the coupling
stated where the coupling lives.

No caller can reach this today: both routes derive the pathname from the host
id, so the one cannot change without the other. The test drives the hook
directly and holds the invariant the wiring is supposed to have, since the thing
protecting it was a property of the call sites and not of this hook.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): persist the last-visited worktree through the mirrored writer

`writeLastVisitedWorktree` noted the write on the mirror and then dropped the
store's promise with `void`. The mirror reports the key as written the moment it
is noted, so a store that refuses the write leaves a value the page is handed on
every `init` and that nothing ever persisted, and the rejection escapes as an
unhandled one because no caller above it holds a catch.

`writeMirroredStorage` in the same module is already exactly this: note first,
persist second, and swallow the rejection deliberately, because a pin that
failed to persist is not a reason to take the workspace off screen. This writer
had grown its own copy of that pair without the last part. Reusing it rather
than adding a local `.catch` is what stops the two copies drifting again, and it
is the boundary that owns the relationship between the mirror and the store.

The test drives a store that refuses the write and listens for an unhandled
rejection, which is the failure the `void` produced and the only way to observe
it from inside a test.

* refactor(mobile): pin the re-arm oracle, and move the query rationale to the rule

Two review nits from round 1, neither changing behaviour.

The re-arm test asserted the session was no longer `checking`, which a failure
state satisfies just as well as a recovery does — the test would have passed on
the opposite of what it is for. It now pins `native-route`, which is the state a
re-armed session actually settles on here: `/h/host-1/tasks` is not the route
the bundle lists, so the reducer answers with the native screen.

The sentence about `?` closing a segment sat in the doc block for the `init`
pathname bounds, which opens by saying that pathname carries no query. Read
top to bottom the block contradicted itself. The rationale belongs beside
`BRIDGE_ROUTE_SEGMENT_SOURCE`, where the shared rule is written and where the
reason is legible: an href carries a query even though a pathname does not, both
are held to the one segment rule, and widening its boundary cannot loosen the
pathname pattern because a `?` fails that character class anywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state what the native router really does with a dot segment

Round 2 review, comment text only.

The rationale beside `BRIDGE_ROUTE_SEGMENT_SOURCE` claimed `/h/..?x` resolves to
`/?x`, borrowing the climb `history.replaceState` performs on the `init`
pathname. That is the wrong sink. An href's sink is the native router, and
expo-router's `resolveHrefStringWithSegments` normalises only an href beginning
with `.`; a rooted one is passed through, its query stripped, and the forked
`getStateFromPath` then matches segments literally against the route patterns. A
dynamic segment compiles to `([^/]+\/)`, which takes `..` as happily as any
other value.

So the harm is not a climb and it is not Unmatched either: `..` is read as the
`[hostId]` a screen is opened for, and the shell opens a host screen for an id
no host has. A different wrong screen from the slash-terminated spellings, and
the same reason one rule covers both patterns. The boundary and the test that
pins it are unchanged; only the sentences describing them are.

The notify header opened by saying three of the four share one guard, one
paragraph above the one explaining that only two ever reach its throw. It now
says both in the same breath.

Jinwoo Hong e2afb5eef9 feat(mobile): the page reads this host and keeps the app's pins (OTA phase C, C1.4) (#21503)
* feat(mobile): the page mounts on the shell's init, with the client injected (OTA phase C, C1.1)

The Route A entry built no client and mounted the route tree immediately, so the
web provider minted its own: it read the page channel, built `BridgeRpcClient`
and fell back to a placeholder that rejected every call. A tree that mounts
before `init` reads synchronous getters against a client that knows no host, no
state and no build, and the first render it records is the wrong one.

The entry now owns the page's one client. It builds it from the channel at
module scope, mounts nothing until `onReady` fires, and stamps the session and
build ids `getShellSession()` returns on the document beside the mount state, so
a screenshot, the render check and a device console read the same three facts.
`client-context.web.tsx` takes that client by injection and serves it from
`acquire()` for every hostId, because the bridge protocol names no host; the
placeholder and its `BridgeTransportUnavailableError` are gone, along with the
entry that pointed at them in the unvalidated-port inventory.

A document with no channel is not inside the shell, so it says `unbridged` and
stops rather than waiting out a backoff nobody answers. The render check gains a
shell double that answers `ready` with `init`, reads the stamped session back off
the document, and proves the gate is real by opening the same route with no
double and finding an empty `#root`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the shell names the screen, and the page routes to it (OTA phase C, C1.2)

The shell serves its document at `/` and refuses every other path, so the page's
own location matches no route in the tree it carries and expo-router paints
Unmatched. Nothing in the document can tell it otherwise, so the screen has to
cross the bridge.

`init` gains an optional `route: { pathname, params }`. The pathname is held to
what a path may be rather than to what a screen may want: rooted, single-slash,
no query and no fragment. A protocol-relative `//host` would make
`history.replaceState` throw a cross-origin SecurityError and take the mount down
with it, and the params are a field of their own so neither side parses a URL.
The shell route supplies it, the screen passes it to B4's hook, and the hook
holds it for the life of one host: the page routes once, before its first render,
so a route that changed afterwards has nothing left to change.

The page writes that URL into its history and then mounts. It also hands the same
URL to `ExpoRoot` as its `location`, because `ExpoRoot` snapshots
`window.location.href` when its module is imported, which is before any frame has
crossed the bridge: without it the router reads the `/` the shell served and
replaces the page's own path right back. A shell too old to name a route leaves
the page with nothing to open, so it paints a panel saying to update the app,
built as elements outside React because the route tree is exactly what cannot
mount there.

Both platforms stop reading the document's URL to decide a load finished. The
page rewrites its own path before its first render, so a document that committed
at `/` reports finishing at `/h/<hostId>`; reading the path withheld `ready`
forever and left the Android WebView hidden behind it. What is left is whether
the load committed, which is the question the state machine already answers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the desktop lists a page route, the shell honours it or stays native (OTA phase C, C1.3)

The worktree list now renders from the desktop's bundle, and which routes do is
negotiated rather than decided on one side. The manifest gains
`routes: [{ pathname, grants }]`, written from one declared list the builder
checks against the tree it bundled, so a declaration naming a screen with no
module fails the build instead of reaching a phone as a page that paints
Unmatched. The field is additive because the phone reads the manifest loosely and
pins no schema version; the desktop's own writer stays `.strict()`, and the stale
comment saying there was no additive path is corrected.

The shell answers for what it can do. A route the bundle does not list, or lists
needing a grant this app does not implement, settles as `native-route` and
downloads nothing; so does a desktop that ships no bundle at all, which is the
one blocked verdict that is not a wall, because a desktop with no bundle declares
no page route and there is no workspace to refuse. The route is answered before
the compat verdict for the same reason: a bundle this shell cannot open is not a
reason to refuse a screen it was never going to open. `app/h/[hostId]/index.tsx`
mounts the shell when the flag is on and takes the native list back as the
fallback, and both routes read the flag through one hook so the census stays the
whole census.

A tap on a worktree row still opens the native session screen. The page posts
`notify { name: 'navigate', href }` behind the `navigate` grant, which is not a
convention: `notify` is a closed union, so an older shell refuses the whole frame
and the page checks the grant before it posts. The shell pushes the target over
the still-mounted view, so Back reveals the page with nothing reloaded.
`route-handoff.ts` and its web sibling are the seam, router-shaped so the list's
own hook and the recorder's adapter are untouched and no golden moves: the web
file wraps the three members that leave the document and hands back any target
outside the page routes `init` named.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the page reads this host and keeps the app's pins (OTA phase C, C1.4)

Three gaps the census named, and the last of them is why the page needed a second
grant.

`expo-secure-store` is `{}` on web, so the page's own `loadHosts()` answered with
an empty array and the list painted "Host not found" over the host the shell had
just opened it for. `init` gains an optional `host`, and `host-store.web.ts`
serves it: the profile the screens read, with no device token and no public key,
because the bridge already carries the connection those would have opened. The
native writes it cannot make — pairing, renaming, recency — settle rather than
throw, since recency orders a list the page never shows.

AsyncStorage's web build is `window.localStorage`, and the page has none worth
having: Android turns DOM storage off and on iOS the origin host is the session
id, so a pin set in the page was gone on the next remount. The builder aliases
the module to a page store whose values are the app's own — `init` primes the
allowlisted keys, a write is applied locally and posted over a new `storage`
grant, and the app is where it lands. The allowlist is two keys and is the whole
fence: everything the app stores shares one namespace, the hybrid shell flag
included, so a page that could write any of it could turn the feature on for a
build that never offered it. A key outside the list is refused and, crucially,
not kept locally either — a pin that looks set and is not is the failure the
grant exists to avoid.

The bridge host is built only once both have been read, because `init` is
answered once per `ready` and carries them: a host that started without them
would have to be torn down to carry them, and the list would already have mounted
against a host it could not name.

`Alert.alert` on a failed host removal is a silent no-op in React Native Web, so
inside the page that failure had no surface at all. It routes to the error the
list already shows, on both platforms.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the page can tell the shell it faulted (OTA phase C, C1.1)

A page that throws where it renders has nowhere to report it: the shell
sees a document that loaded and a view that never painted, so it waits
on a blank page forever. This adds the one frame that says so.

`notify { name: 'fault' }` carries the capture an `error` frame already
carries, so both directions share one bound and one reader. It rides a
grant because `notify` is a closed list on both sides: a page served by
a newer desktop into an older shell would have the whole frame refused,
so the page asks `init.grants.native` first and stays quiet on a no.

The shell answers it as `document-load-failed`, which is what happened.
That reason drops the generation and downloads once, so a page broken
by bytes this host has since replaced recovers, and one broken by its
own code stops at the failure screen rather than a blank one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): give the bridge's notifications and the host's errors their own modules

The fault report took both files over the 300-line cap, so each gives up
the group that was already separable. The page's one-way members move to
`bridge-client-notifications.ts`, which is also where the two policies
that split them can be stated: the two the native contract declares throw
before a session, and the fault report never throws at all. The host's
three error classes move to `bridge-host-errors.ts`, the mirror of the
page's own `bridge-client-errors.ts`.

No behaviour changes. The commit before this one is over the cap on its
own, which a forward-only history is the reason to say rather than hide.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): one boundary under the page's root, reporting to the shell (OTA phase C, C1.1)

Nothing in `app/h/**` exports an `ErrorBoundary` and `ExpoRoot` provides
no global one, so a throw while a route renders — or a route module that
rejects once the manifest is lazy — unmounts the tree and leaves a blank
document. The shell sees a load that finished and waits on it forever.

The entry now wraps what it mounts on `init` in one boundary that posts
the throw over the bridge. Above `ExpoRoot`, not inside its wrapper: a
route that cannot be resolved throws where the router renders it, and a
boundary below the router never sees that.

It renders nothing and offers nothing to press. The generation is on disk
and was hash-checked before the view loaded it, so the same bytes throw
again and a retry here would only throw twice; recovery belongs to the
shell, which drops the generation on the report.

The render check now grants the fault and collects what the page posts
into the errors every case already asserts empty, because a throw the
boundary caught paints nothing and logs nothing a `pageerror` listener
would hear.

* fix(mobile): write the page-fault callback ref after the commit, not during render

React may replay or discard a render, so the write belongs in the commit phase. Layout,

* feat(mobile): bound the wait for a page that never says a word (OTA phase C, C1.1)

A route module that throws while the bundle is evaluated takes the entry with it. The
document still commits and the WebView still reports it loaded, but no boundary mounts,
no fault is posted and no frame is ever sent, so the session sat in `ready` behind a
blank view forever.

The native view's finished load starts a clock; the page's first `ready` stops it;
expiry is `document-load-failed`, which deletes the generation and fetches once. Nothing
cancels the timer — a `ready` that lands first makes the expiry a no-op — so the runner
owns a clock and the reducer owns every decision.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(config): make a route chunk throw, so the render check proves the boundary reports

The check folded page faults into its errors but nothing ever produced one, so a boundary
that stopped reporting would have stayed green. The server now serves one real route
chunk with a throw in front of it: the module still links, so the failure is an
evaluation throw where the router renders, which is exactly what the boundary is for.

* fix(mobile): make the host enforce the grants it issued, and hear nothing before ready

`forwardNotify` acted on any frame that parsed, including a `fault` from a page that had
never asked for a session and therefore held no grant. Both refusals now go through one
rule the host shares with the frame it sends, so the list a page is told about and the
list it will be served cannot drift.

Inert while every page is offered `fault`; the ungranted arm is what C1.3 needs the
moment a grant belongs to a route rather than to the protocol.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): refuse a route no page can open, rather than blanking the WebView (OTA phase C, C1.2)

`sendInit` put `options.route` straight on the wire and only the page's decoder checked
it, so an out-of-contract pathname made the page refuse the whole `init`, ask again on
its 2 s backoff forever, and the shell un-hide a view that would never paint. The only
trace was a `console.warn` inside the WebView.

Three changes, one failure mode. The host parses the route at construction and serves no
session at all when it will not do, reporting it as a shell failure. The pathname rule
refuses empty segments, dot segments and backslashes anywhere, because `replaceState`
normalises `/../../etc` to `/etc` and `/h/a\b` to `/h/a/b` and the page then renders
whatever came out. And the producer encodes the host id it interpolates, which is how
one carrying a query, a fragment or whitespace got there.

* fix(mobile): make a handoff mean the shell took it, not that a frame left (OTA phase C, C1.3)

`handOff` returned `client.notifyNavigate(href)`, which answers whether the frame left
the page and never whether the shell accepted it. Two hrefs the app builds today were
posted, answered true and suppressed the local fallback, so the tap did nothing at all:
the Connection-log link's object form, which `String` turns into `[object Object]`, and
any href carrying a fragment, because the pathname is stripped to match and the whole
href is what goes on the wire.

Object hrefs now resolve the way the router resolves them, and the string is checked
against the envelope's own pattern and cap before it is posted; anything that fails
falls through to the local router, which is the policy this module already states.
Whether a target names a screen that exists is shape's business no longer, and the
comment says C1.7 owns it.

* fix(mobile): keep a failed action off the whole screen and the page's store honest (OTA phase C, C1.4)

Five, from one round of review.

A removal that fails no longer writes the identity error: that one is an early return
over the header, the list and the overlays, with nothing to dismiss it and nothing left
to render the confirm it re-opens. It goes to a dismissible line above the list instead,
on both platforms, cleared by the next confirmed refresh.

`init` reads the allowlisted keys on every answer rather than capturing them at mount, so
a document that reloads inside one mount is primed from after its own writes. The read
stays synchronous: the page refuses every member until `init` lands and the golden
recorder mounts a screen in the same turn it drains one, so a promise here moves the
first render of every bridged replay.

A profile read that rejects is now a shell failure with a diagnostic instead of a `ready`
session with no host behind it and a page asking forever. The page bounds a value by the
envelope's own constant rather than caching what the wire drops. And a write is held to
the keys this page was handed, so one host's page cannot rewrite another's pinned list.

The casting gate reads a `SAFETY:` rationale off the line directly above the assertion,
and a wrapped comment puts a comment there instead. Two of the four were not assertions
worth keeping at all: a hoisted fixture says its own type, and the router comes from the
mock the file already installs.

* test(mobile): assert the two fixtures in place, not through a widened binding

`const x: unknown = …` followed by `x as T` is the widen-then-assert the anti-slop gate
refuses, and rightly: the evidence is discarded and then invented again. The assertion
belongs at the literal, with its rationale on the line above it.

a screen nobody asked for, with no refusal anywhere. The one segment rule both

still lets an escape inside a name through.

* fix(mobile): hand the page the app's storage as it stands, not one init late

The page is handed its allowlisted keys on every `init`, built synchronously, and the app writes
two of them from its own native screens. The shell's map was only re-read after a ready, so a
native write between two readies reached the init after next: the drawer opened on the repo the
user left. The map is now module-scoped and every writer of an allowlisted key notes it as it
writes, so the init that answers a ready already carries it. The store read only seats the map,
and a read that started before a write no longer puts the older value back.

* refactor(mobile): keep the storage mirror in the storage tree

The app's own writers had to reach into `src/mobile-web-shell/` to note a write, which is the
dependency the wrong way round: the shell is what is built on the app's storage, not the other way.
The mirror moves to `src/storage/` and no longer knows which keys the page is allowed; the caller
names them on every read and every seat, so the allowlist stays where it is enforced. No behaviour
change.

`bridge-rpc-client-frames.test.ts` reached 835 counted lines once C0.8 and C1.1
both added cases to it, over the 800 the lint allows. The split follows the two
modules those changes extracted, so each suite now names the module it covers.

`bridge client page faults` moves to `bridge-client-notifications.test.ts` (the
outbound notify surface) and `bridge client refusals and send failures` to
`bridge-client-inbound-frames.test.ts` (the reader, including the refused-event
release that cancels at the shell). The seven suites that exercise the client as
a whole stay put. The fake port all three drive moves to
`bridge-page-client-test-harness.ts` rather than being copied three times.

No case changed and none was dropped: 48 `it` cases before, 37 + 4 + 7 after,
and all nine `describe` bodies compare byte-identical to their originals.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): type the shared init fixture as the member a case reads

The harness exported `INIT` as `BridgeHostMessage`. While it was a module-local
const, control flow narrowed it to the `init` member at each use, so
`INIT.grants` read fine. An imported binding keeps its declared type instead, so
the same read lost `grants` to the union and the tests ratchet went red.

Declared as the init member, which is what every case already treats it as. No
cast: the object literal is checked against the narrower type directly.

`INIT` was the only exported fixture with this shape. `CONNECTION` is `as const`,
`GRANTS` is inferred, and nothing reads a member off an `eventFrame` result.

Jinwoo Hong ac4dc6599b feat(mobile): the desktop lists a page route, the shell honours it or stays native (OTA phase C, C1.3) (#21502)
* feat(mobile): the page mounts on the shell's init, with the client injected (OTA phase C, C1.1)

The Route A entry built no client and mounted the route tree immediately, so the
web provider minted its own: it read the page channel, built `BridgeRpcClient`
and fell back to a placeholder that rejected every call. A tree that mounts
before `init` reads synchronous getters against a client that knows no host, no
state and no build, and the first render it records is the wrong one.

The entry now owns the page's one client. It builds it from the channel at
module scope, mounts nothing until `onReady` fires, and stamps the session and
build ids `getShellSession()` returns on the document beside the mount state, so
a screenshot, the render check and a device console read the same three facts.
`client-context.web.tsx` takes that client by injection and serves it from
`acquire()` for every hostId, because the bridge protocol names no host; the
placeholder and its `BridgeTransportUnavailableError` are gone, along with the
entry that pointed at them in the unvalidated-port inventory.

A document with no channel is not inside the shell, so it says `unbridged` and
stops rather than waiting out a backoff nobody answers. The render check gains a
shell double that answers `ready` with `init`, reads the stamped session back off
the document, and proves the gate is real by opening the same route with no
double and finding an empty `#root`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the shell names the screen, and the page routes to it (OTA phase C, C1.2)

The shell serves its document at `/` and refuses every other path, so the page's
own location matches no route in the tree it carries and expo-router paints
Unmatched. Nothing in the document can tell it otherwise, so the screen has to
cross the bridge.

`init` gains an optional `route: { pathname, params }`. The pathname is held to
what a path may be rather than to what a screen may want: rooted, single-slash,
no query and no fragment. A protocol-relative `//host` would make
`history.replaceState` throw a cross-origin SecurityError and take the mount down
with it, and the params are a field of their own so neither side parses a URL.
The shell route supplies it, the screen passes it to B4's hook, and the hook
holds it for the life of one host: the page routes once, before its first render,
so a route that changed afterwards has nothing left to change.

The page writes that URL into its history and then mounts. It also hands the same
URL to `ExpoRoot` as its `location`, because `ExpoRoot` snapshots
`window.location.href` when its module is imported, which is before any frame has
crossed the bridge: without it the router reads the `/` the shell served and
replaces the page's own path right back. A shell too old to name a route leaves
the page with nothing to open, so it paints a panel saying to update the app,
built as elements outside React because the route tree is exactly what cannot
mount there.

Both platforms stop reading the document's URL to decide a load finished. The
page rewrites its own path before its first render, so a document that committed
at `/` reports finishing at `/h/<hostId>`; reading the path withheld `ready`
forever and left the Android WebView hidden behind it. What is left is whether
the load committed, which is the question the state machine already answers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the desktop lists a page route, the shell honours it or stays native (OTA phase C, C1.3)

The worktree list now renders from the desktop's bundle, and which routes do is
negotiated rather than decided on one side. The manifest gains
`routes: [{ pathname, grants }]`, written from one declared list the builder
checks against the tree it bundled, so a declaration naming a screen with no
module fails the build instead of reaching a phone as a page that paints
Unmatched. The field is additive because the phone reads the manifest loosely and
pins no schema version; the desktop's own writer stays `.strict()`, and the stale
comment saying there was no additive path is corrected.

The shell answers for what it can do. A route the bundle does not list, or lists
needing a grant this app does not implement, settles as `native-route` and
downloads nothing; so does a desktop that ships no bundle at all, which is the
one blocked verdict that is not a wall, because a desktop with no bundle declares
no page route and there is no workspace to refuse. The route is answered before
the compat verdict for the same reason: a bundle this shell cannot open is not a
reason to refuse a screen it was never going to open. `app/h/[hostId]/index.tsx`
mounts the shell when the flag is on and takes the native list back as the
fallback, and both routes read the flag through one hook so the census stays the
whole census.

A tap on a worktree row still opens the native session screen. The page posts
`notify { name: 'navigate', href }` behind the `navigate` grant, which is not a
convention: `notify` is a closed union, so an older shell refuses the whole frame
and the page checks the grant before it posts. The shell pushes the target over
the still-mounted view, so Back reveals the page with nothing reloaded.
`route-handoff.ts` and its web sibling are the seam, router-shaped so the list's
own hook and the recorder's adapter are untouched and no golden moves: the web
file wraps the three members that leave the document and hands back any target
outside the page routes `init` named.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the page can tell the shell it faulted (OTA phase C, C1.1)

A page that throws where it renders has nowhere to report it: the shell
sees a document that loaded and a view that never painted, so it waits
on a blank page forever. This adds the one frame that says so.

`notify { name: 'fault' }` carries the capture an `error` frame already
carries, so both directions share one bound and one reader. It rides a
grant because `notify` is a closed list on both sides: a page served by
a newer desktop into an older shell would have the whole frame refused,
so the page asks `init.grants.native` first and stays quiet on a no.

The shell answers it as `document-load-failed`, which is what happened.
That reason drops the generation and downloads once, so a page broken
by bytes this host has since replaced recovers, and one broken by its
own code stops at the failure screen rather than a blank one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): give the bridge's notifications and the host's errors their own modules

The fault report took both files over the 300-line cap, so each gives up
the group that was already separable. The page's one-way members move to
`bridge-client-notifications.ts`, which is also where the two policies
that split them can be stated: the two the native contract declares throw
before a session, and the fault report never throws at all. The host's
three error classes move to `bridge-host-errors.ts`, the mirror of the
page's own `bridge-client-errors.ts`.

No behaviour changes. The commit before this one is over the cap on its
own, which a forward-only history is the reason to say rather than hide.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): one boundary under the page's root, reporting to the shell (OTA phase C, C1.1)

Nothing in `app/h/**` exports an `ErrorBoundary` and `ExpoRoot` provides
no global one, so a throw while a route renders — or a route module that
rejects once the manifest is lazy — unmounts the tree and leaves a blank
document. The shell sees a load that finished and waits on it forever.

The entry now wraps what it mounts on `init` in one boundary that posts
the throw over the bridge. Above `ExpoRoot`, not inside its wrapper: a
route that cannot be resolved throws where the router renders it, and a
boundary below the router never sees that.

It renders nothing and offers nothing to press. The generation is on disk
and was hash-checked before the view loaded it, so the same bytes throw
again and a retry here would only throw twice; recovery belongs to the
shell, which drops the generation on the report.

The render check now grants the fault and collects what the page posts
into the errors every case already asserts empty, because a throw the
boundary caught paints nothing and logs nothing a `pageerror` listener
would hear.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): write the page-fault callback ref after the commit, not during render

React may replay or discard a render, so the write belongs in the commit phase. Layout,
not passive, and declared above the host's effect: a native frame can arrive between a
commit and a passive effect, and the host must already hold this render's callback.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): write the route ref after the commit, not during render

Same class as the page-fault ref: render must stay pure because React can replay or
discard it. Folded into the one commit-phase effect above the host's.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): write the page-route and navigate refs after the commit

Same class again: the last two writes this branch adds join the commit-phase effect, so
nothing this hook holds is written while React is rendering.

* test(mobile): take the boundary test to C0.5's fake-client pair

`createBridgePortPair` is generic over the shell client now; the fake-client form this
test wants is `createFakeBridgePortPair`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): bound the wait for a page that never says a word (OTA phase C, C1.1)

A route module that throws while the bundle is evaluated takes the entry with it. The
document still commits and the WebView still reports it loaded, but no boundary mounts,
no fault is posted and no frame is ever sent, so the session sat in `ready` behind a
blank view forever.

The native view's finished load starts a clock; the page's first `ready` stops it;
expiry is `document-load-failed`, which deletes the generation and fetches once. Nothing
cancels the timer — a `ready` that lands first makes the expiry a no-op — so the runner
owns a clock and the reducer owns every decision.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(config): make a route chunk throw, so the render check proves the boundary reports

The check folded page faults into its errors but nothing ever produced one, so a boundary
that stopped reporting would have stayed green. The server now serves one real route
chunk with a throw in front of it: the module still links, so the failure is an
evaluation throw where the router renders, which is exactly what the boundary is for.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make the host enforce the grants it issued, and hear nothing before ready

`forwardNotify` acted on any frame that parsed, including a `fault` from a page that had
never asked for a session and therefore held no grant. Both refusals now go through one
rule the host shares with the frame it sends, so the list a page is told about and the
list it will be served cannot drift.

Inert while every page is offered `fault`; the ungranted arm is what C1.3 needs the
moment a grant belongs to a route rather than to the protocol.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): refuse a route no page can open, rather than blanking the WebView (OTA phase C, C1.2)

`sendInit` put `options.route` straight on the wire and only the page's decoder checked
it, so an out-of-contract pathname made the page refuse the whole `init`, ask again on
its 2 s backoff forever, and the shell un-hide a view that would never paint. The only
trace was a `console.warn` inside the WebView.

Three changes, one failure mode. The host parses the route at construction and serves no
session at all when it will not do, reporting it as a shell failure. The pathname rule
refuses empty segments, dot segments and backslashes anywhere, because `replaceState`
normalises `/../../etc` to `/etc` and `/h/a\b` to `/h/a/b` and the page then renders
whatever came out. And the producer encodes the host id it interpolates, which is how
one carrying a query, a fragment or whitespace got there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make a handoff mean the shell took it, not that a frame left (OTA phase C, C1.3)

`handOff` returned `client.notifyNavigate(href)`, which answers whether the frame left
the page and never whether the shell accepted it. Two hrefs the app builds today were
posted, answered true and suppressed the local fallback, so the tap did nothing at all:
the Connection-log link's object form, which `String` turns into `[object Object]`, and
any href carrying a fragment, because the pathname is stripped to match and the whole
href is what goes on the wire.

Object hrefs now resolve the way the router resolves them, and the string is checked
against the envelope's own pattern and cap before it is posted; anything that fails
falls through to the local router, which is the policy this module already states.
Whether a target names a screen that exists is shape's business no longer, and the
comment says C1.7 owns it.

URL to `ExpoRoot` as its `location`, because `ExpoRoot` snapshots
`window.location.href` when its module is imported, which is before any frame has
crossed the bridge: without it the router reads the `/` the shell served and
replaces the page's own path right back. A shell too old to name a route leaves
the page with nothing to open, so it paints a panel saying to update the app,
built as elements outside React because the route tree is exactly what cannot
mount there.

Both platforms stop reading the document's URL to decide a load finished. The
page rewrites its own path before its first render, so a document that committed
at `/` reports finishing at `/h/<hostId>`; reading the path withheld `ready`
forever and left the Android WebView hidden behind it. What is left is whether
the load committed, which is the question the state machine already answers.

* feat(mobile): the page can tell the shell it faulted (OTA phase C, C1.1)

A page that throws where it renders has nowhere to report it: the shell
sees a document that loaded and a view that never painted, so it waits
on a blank page forever. This adds the one frame that says so.

`notify { name: 'fault' }` carries the capture an `error` frame already
carries, so both directions share one bound and one reader. It rides a
grant because `notify` is a closed list on both sides: a page served by
a newer desktop into an older shell would have the whole frame refused,
so the page asks `init.grants.native` first and stays quiet on a no.

The shell answers it as `document-load-failed`, which is what happened.
That reason drops the generation and downloads once, so a page broken
by bytes this host has since replaced recovers, and one broken by its
own code stops at the failure screen rather than a blank one.

* refactor(mobile): give the bridge's notifications and the host's errors their own modules

The fault report took both files over the 300-line cap, so each gives up
the group that was already separable. The page's one-way members move to
`bridge-client-notifications.ts`, which is also where the two policies
that split them can be stated: the two the native contract declares throw
before a session, and the fault report never throws at all. The host's
three error classes move to `bridge-host-errors.ts`, the mirror of the
page's own `bridge-client-errors.ts`.

No behaviour changes. The commit before this one is over the cap on its
own, which a forward-only history is the reason to say rather than hide.

* feat(mobile): one boundary under the page's root, reporting to the shell (OTA phase C, C1.1)

Nothing in `app/h/**` exports an `ErrorBoundary` and `ExpoRoot` provides
no global one, so a throw while a route renders — or a route module that
rejects once the manifest is lazy — unmounts the tree and leaves a blank
document. The shell sees a load that finished and waits on it forever.

The entry now wraps what it mounts on `init` in one boundary that posts
the throw over the bridge. Above `ExpoRoot`, not inside its wrapper: a
route that cannot be resolved throws where the router renders it, and a
boundary below the router never sees that.

It renders nothing and offers nothing to press. The generation is on disk
and was hash-checked before the view loaded it, so the same bytes throw
again and a retry here would only throw twice; recovery belongs to the
shell, which drops the generation on the report.

The render check now grants the fault and collects what the page posts
into the errors every case already asserts empty, because a throw the
boundary caught paints nothing and logs nothing a `pageerror` listener
would hear.

* feat(mobile): bound the wait for a page that never says a word (OTA phase C, C1.1)

A route module that throws while the bundle is evaluated takes the entry with it. The
document still commits and the WebView still reports it loaded, but no boundary mounts,
no fault is posted and no frame is ever sent, so the session sat in `ready` behind a
blank view forever.

The native view's finished load starts a clock; the page's first `ready` stops it;
expiry is `document-load-failed`, which deletes the generation and fetches once. Nothing
cancels the timer — a `ready` that lands first makes the expiry a no-op — so the runner
owns a clock and the reducer owns every decision.

* test(config): make a route chunk throw, so the render check proves the boundary reports

The check folded page faults into its errors but nothing ever produced one, so a boundary
that stopped reporting would have stayed green. The server now serves one real route
chunk with a throw in front of it: the module still links, so the failure is an
evaluation throw where the router renders, which is exactly what the boundary is for.

* fix(mobile): make the host enforce the grants it issued, and hear nothing before ready

`forwardNotify` acted on any frame that parsed, including a `fault` from a page that had
never asked for a session and therefore held no grant. Both refusals now go through one
rule the host shares with the frame it sends, so the list a page is told about and the
list it will be served cannot drift.

Inert while every page is offered `fault`; the ungranted arm is what C1.3 needs the
moment a grant belongs to a route rather than to the protocol.

* fix(mobile): refuse a route no page can open, rather than blanking the WebView (OTA phase C, C1.2)

`sendInit` put `options.route` straight on the wire and only the page's decoder checked
it, so an out-of-contract pathname made the page refuse the whole `init`, ask again on
its 2 s backoff forever, and the shell un-hide a view that would never paint. The only
trace was a `console.warn` inside the WebView.

Three changes, one failure mode. The host parses the route at construction and serves no
session at all when it will not do, reporting it as a shell failure. The pathname rule
refuses empty segments, dot segments and backslashes anywhere, because `replaceState`
normalises `/../../etc` to `/etc` and `/h/a\b` to `/h/a/b` and the page then renders
whatever came out. And the producer encodes the host id it interpolates, which is how
one carrying a query, a fragment or whitespace got there.

* fix(mobile): start a new flow when the shell view remounts

A remount cleared `pageReady` but left the flow alone, so the wait the retired
document armed still matched. It expired onto the page that replaced it, took a

A refused `notify` fell through to the line about a view outliving its host,

bury one reaching past what it was told.

* fix(mobile): refuse a dot segment however the route spells it

A URL parser percent-decodes a path before it resolves it, so `/h/%2e%2e/x`
climbed out of the `/h/` prefix exactly as `/h/../x` does and landed the page on
a screen nobody asked for, with no refusal anywhere. The one segment rule both
patterns share now reads the encoded spellings as the dot segments they are, and
still lets an escape inside a name through.

`bridge-rpc-client-frames.test.ts` reached 835 counted lines once C0.8 and C1.1
both added cases to it, over the 800 the lint allows. The split follows the two
modules those changes extracted, so each suite now names the module it covers.

`bridge client page faults` moves to `bridge-client-notifications.test.ts` (the
outbound notify surface) and `bridge client refusals and send failures` to
`bridge-client-inbound-frames.test.ts` (the reader, including the refused-event
release that cancels at the shell). The seven suites that exercise the client as
a whole stay put. The fake port all three drive moves to
`bridge-page-client-test-harness.ts` rather than being copied three times.

No case changed and none was dropped: 48 `it` cases before, 37 + 4 + 7 after,
and all nine `describe` bodies compare byte-identical to their originals.

The harness exported `INIT` as `BridgeHostMessage`. While it was a module-local

`INIT.grants` read fine. An imported binding keeps its declared type instead, so
the same read lost `grants` to the union and the tests ratchet went red.

Declared as the init member, which is what every case already treats it as. No
cast: the object literal is checked against the narrower type directly.

`INIT` was the only exported fixture with this shape. `CONNECTION` is `as const`,
`GRANTS` is inferred, and nothing reads a member off an `eventFrame` result.

Jinwoo Hong d043cfbbee feat(mobile): the page mounts on the shell's init, with the client injected and a fault boundary (OTA phase C, C1.1) (#21500)
* feat(mobile): the page mounts on the shell's init, with the client injected (OTA phase C, C1.1)

The Route A entry built no client and mounted the route tree immediately, so the
web provider minted its own: it read the page channel, built `BridgeRpcClient`
and fell back to a placeholder that rejected every call. A tree that mounts
before `init` reads synchronous getters against a client that knows no host, no
state and no build, and the first render it records is the wrong one.

The entry now owns the page's one client. It builds it from the channel at
module scope, mounts nothing until `onReady` fires, and stamps the session and
build ids `getShellSession()` returns on the document beside the mount state, so
a screenshot, the render check and a device console read the same three facts.
`client-context.web.tsx` takes that client by injection and serves it from
`acquire()` for every hostId, because the bridge protocol names no host; the
placeholder and its `BridgeTransportUnavailableError` are gone, along with the
entry that pointed at them in the unvalidated-port inventory.

A document with no channel is not inside the shell, so it says `unbridged` and
stops rather than waiting out a backoff nobody answers. The render check gains a
shell double that answers `ready` with `init`, reads the stamped session back off
the document, and proves the gate is real by opening the same route with no
double and finding an empty `#root`.

A page that throws where it renders has nowhere to report it: the shell

`notify { name: 'fault' }` carries the capture an `error` frame already

The shell answers it as `document-load-failed`, which is what happened.
That reason drops the generation and downloads once, so a page broken

own code stops at the failure screen rather than a blank one.

Jinwoo Hong f2fd18c820 test(mobile): make the bridged recording-corpus replay a CI gate and pin the C1 page closure (OTA phase C, C1.6) (#21533)
* test(mobile): the bridged corpus replay is a gate, not an opt-in flag (OTA phase C, C1.6)

`rpc-recording-through-bridge.test.ts` replays all 787 goldens through the page
bridge and pins how far that bridge is from byte-identical. It only ran when
`RPC_FOUNDATION_BRIDGE=1` was set, which CI did in a step of its own. A gate
whose CI job has to remember to set a variable is opt-in, and a branch that
widened the divergence with that step edited away would have been measured by
nobody.

The suite now runs by default and `RPC_FOUNDATION_BRIDGE=0` skips it, for a
local run that does not want the three minutes. `BRIDGED_PARITY_OFF` names the
one value that skips, so an unset or mistyped variable still runs the gate.

The dedicated CI step goes with it: `pnpm test` collects the file already, so
keeping the step would have run the same 788 tests twice in one job. Vitest
gives the file a worker beside the rest of the suite, so the marginal wall time
is a fraction of the ~3 min it takes alone.

* test(mobile): pin the bridged verdict of every C1-page-closure golden by id (OTA phase C, C1.6)

The bridged replay certifies the corpus in counts over 787 goldens, and a count
is the wrong instrument for the claim C1 needs. C1 moves one domain to the web:
`app/h/_layout.tsx`, `app/h/[hostId]/index.tsx` and their import closure. A
golden recorded at a call site in there that stopped replaying byte-identically
is paid for by any of the other 684 that started, and every existing assertion
still passes.

`c1-page-closure.ts` names the 22 families and 103 goldens of that closure and
pins each one to the verdict it gives: 54 byte-identical, 49 in four of the five
classes the suite already excludes, all of them recorder observation artifacts
whose wire bytes C0.5 and C0.8 proved identical. Membership is checked per
family, not against the flat id list, so a golden newly derived into a family
this domain owns arrives as a finding instead of being missed for never having
been pinned. A closure golden may only be excluded into a class that carries a
reason in `BRIDGED_PARITY_EXCLUSIONS`.

Two full-corpus assertions go with it. `identical` was a floor; it is now the
exact 787 minus the excluded classes. And the run's own size is pinned to the
corpus: every class is an upper bound, so without that a corpus that lost
goldens outside the identical set satisfied all of them.

* test(mobile): move a closure golden to a verdict it is not already pinned to (OTA phase C, C1.6)

The drift test took whichever golden the pin lists first and moved it to
`params-undefined`. Nothing said that golden was not pinned to that class
already, and the day one is, the test asserts a change it never made. Pick the
first golden whose verdict is something else, and assert the pair of verdicts
the line reports rather than just the new one.

* test(mobile): pin `identical` to its baseline, not to the run's own exclusions (OTA phase C, C1.6)

`identical: pinned - excludedCount` took `excludedCount` from the run, and the sum
assertion above it already forces `total(counts) === excludedCount`, so the pair
reduced to `corpus === pinned`: only the size of the corpus was pinned. With every
per-class check an upper bound, a golden moving out of an excluded class into
`identical` satisfied all of them.

`bridgedParityTallyDrift` pins every number to `BRIDGED_PARITY_BASELINE` exactly,
`identical` among them, and its own tests encode the mutation: one
`result-absent-settlement` golden reported `identical` is two drift lines, where
before it was a green run.

`c1PageClosureExclusions()` reads `C1_PAGE_CLOSURE` and nothing the run produced, so
asserting on it inside the three-minute replay bought nothing the cheap suite next
door does not already buy. `c1-page-closure.test.ts` makes the same assertion with a
presence precondition on top, which is the stronger of the two.

The comment beside the tally counted two checks above it; there are three, and a
golden that moved out of an excluded class into `identical` is invisible to all of
them: `result-absent-settlement` is past the nameable cap, so membership drift never
looks at it, and lowering it lowers the exclusion sum with it.

`BridgeReplyPayloadSchema` required `_meta` on both arms. The predicate the

`runtimeId`. The page's reader was strictly narrower than the transport it

The reader is now that predicate itself, imported rather than restated: one
module owns the shape, and a widened reader is safe in both directions. `{ ok:
true }` with no `result` key stays refused, because `isRpcResponse` drops it too.

Killer test: `the reply reader is the native acceptance predicate` compares the
page's verdict against `isRpcResponse` over eleven payloads; six of them were
red before this change.

* fix(mobile): settle the exchange a refused bridge frame was answering

A host frame the page's reader refuses was reported and dropped, and the
request it answered stayed pending for the life of the document. A screen has
no recovery from that: `sendRequest` never settles, so nothing rerenders and
nothing retries.

The page now salvages the id out of the refused frame, through the same caps
the reader applies, and settles it — but only when it already holds that
exchange, so a salvaged id reaches nothing the page did not open itself. A
request rejects with `BridgeReplyRefusedError`, which carries the refusal and is
now marked delivery-unknown at construction: the shell answered, so the desktop
has already run the request and a caller told this was a definite failure would
offer to retry what already happened. A subscription ends the way a refused
`subscribe` ends today.

`bridge-rpc-client.ts` was at the 300-line ceiling, so the inbound routing moved
to `bridge-client-inbound-frames.ts` and the diagnostic vocabulary, which both
sides raise, to `bridge-client-diagnostics.ts`. No `max-lines` disable.

Killer tests: `settles the request a reply it could not read was answering, on
the same turn` (hung to a 5s timeout before) and `ends the stream an event it
could not read belonged to`.

* test(mobile): name what the bridged replay still excludes, and ratchet the pin

The class this harness was landed to name is closed, so the pin says so:
`reply-meta-required` is 0 and has no exclusion reason, which is what
`divergence-classes.test.ts` now requires of any class the run is allowed to
count. `BRIDGED_PARITY_EXCLUSIONS` gives each remaining class the reason it is a
bound on the claim rather than a defect, the run prints the excluded total
beside those reasons, and one assertion states the whole claim: nothing diverges
that no predicate has named.

Measured, not argued, for `params-undefined`: all ten scenarios that send an own
property valued `undefined` already record the key as absent from the bytes
their request put on the wire — `tw-smart-search-all-providers` records
`{"filter":"assigned","limit":50}` with `workspaceId` already gone — so the
bridged run sends the identical frame. What differs is the object
`ScriptedRpcTransport.complete` matches a scenario step against, one level above
any serialization. The projection named as the fix is not where it lives:
`projectMobileRpcRequestParams` rewrites `worktree.ps` alone, none of the ten
calls it, and the bridge host forwards into the same `StableLogicalRpcClient`
the native screens hold, so there is no shell-side copy to move.

`divergence-evidence.test.ts` asserted the narrow reader that the `_meta`
widening removed; it now pins that the counterfactual changes no verdict, which
is what makes it a detector for that reader coming back.

* docs(mobile): say the remaining classes total 391 in one line

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): read the throw a bridged golden died on, not just the scenario

The `params-undefined` arm named a class from two facts that never met: the run
threw, and the scenario somewhere scripts a param key valued `undefined`. Any
failure inside those ten scenarios was that class, reported by nothing. A seeded
wire bug — one extra own key on every request's params — put 627 goldens in
`unclassified` and still left `params-undefined` at exactly 33, all corrupted;
scoped to `linear.listIssues` alone it stayed green.

The evidence now carries the step the scripted transport refused, the paths the
scenario values `undefined` on it, and every path where the params that arrived
differ from the ones it scripts — read off the frames the page posted, not off
the message. The class needs every path that moved to be one of the scripted
`undefined` ones, and at least one to have moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): cancel the stream a refused frame belonged to, not just end it

Ending a stream deletes the page's record and posts nothing back. That is right
for `end` and `error`, where the shell has already retired it, and wrong for a
frame this reader refused: the shell is still serving that stream, so later valid
frames on the id were dropped with no diagnostic, no ack went back, and the only
release left was the host's overflow backstop, which counts unacked frames and so
never fires on a stream that has gone quiet. A newer shell adding a member to a
closed list — a new `binary.format`, say — lands exactly there.

`abandon` posts the cancel and tells the listener; `failExchange` picks it over
`end` for the one path where the shell has not let go.

Six goldens move to a new named class for what the cancel changes in the replay.
The unsubscribe it publishes is a physical payload the native run has no
counterpart for, and it takes the recorder's next occurrence name for that
method, so the scenario stops matching before there is a recording. Four came
from `result-absent-observation` and two from `write-ordinal`; the sum over the
corpus is unchanged and nothing stopped replaying byte-identically.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): hold the bridged pin to the size of the corpus

Each class in the pin is an upper bound and `identical` a lower one, so nothing
stopped a single class being loosened on its own: raising `params-undefined` by
one passed every assertion the flagged run makes. The comment already claimed the
total was fixed at the corpus; this counts the goldens on disk and checks it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): name the two refusals that can settle nothing at all

`oversized` is decided on the raw string and `malformed-json` on a parse that did
not finish, so neither frame ever yields an id and neither can settle the
exchange it was answering. Nothing on the page settles those: `close` or a shell
replacement releases the slot, and otherwise it is held for the life of the
document. Neither arises from a host that is behaving — it chunks at the frame
cap and answers a body over `BRIDGE_MAX_REPLY_BYTES` with an `error` frame — but
the boundary was unstated and untested, which is how it reads as covered.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say which way each number in the bridged pin may move

The comment said the pin moves down and never up, two lines above a class that
went from 338 to 341 when a fix changed which difference a run meets first. Both
are true of different halves of it, so say which: `identical` only moves up, a
class only moves down, and two excluded classes may trade members in one edit
that leaves the sum alone. The sum is now checked, so that trade cannot hide a
golden that stopped replaying byte-identically.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin which goldens are in a class, not only how many

A count is blind to a trade. Every predicate reads the scenario rather
than the frame the page refused, so a golden that started refusing for
real can walk into an excluded class while another walks out, and the
counts, the sum and the `identical` floor all still hold.

Jinwoo Hong f24f38bd41 test(mobile): certify the golden corpus through the page bridge (OTA phase C, C0.5) (#21485)
* test(mobile): record the golden corpus through the page bridge (OTA phase C, C0.5)

`ScriptedRpcTransport` gains one seam: an optional `wrapClient`, applied
between the recorder's own instrumentation and the logical client, so a
recording can be driven through another transport without the runner
learning which one. `runRecording` passes it through.

The instrumentation moves outside the seam. `ordinal` orders a logical
`sendRequest` against the recording's device writes and physical payloads,
and the operation makes that call at the same moment with or without a
wrapper; stamping it under one times the wrapper's forwarded send instead,
which the unwrapped recording has no counterpart for. Measured: 131 goldens
move their sender ordinal under the seam, none above it. The name a physical
send is filed by therefore becomes a queue rather than one slot, taken on the
inside of the wrapper — a wrapper that forwards on a microtask arrives after
the next logical call has been made, and one slot hands both sends the second
name. Underflow throws; a wrapper that drops a send is a finding.

`rpc-recording-through-bridge.test.ts` is the harness: every golden recorded
again with `BridgeRpcClient` over an in-memory port pair to a `createBridgeHost`
holding the scripted client, compared body for body against the committed file.
One FIFO per direction, delivery on a microtask, and the `init` handshake
delivered in place before anything mounts.

It is opt-in behind `RPC_FOUNDATION_BRIDGE=1` and does not pass yet. 391 of 787
goldens diverge, for four causes that are findings about the bridge rather than
about the corpus; the suite's header names each one with its count, and flipping
the gate is one line once they close.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): repin the recording corpus and refresh its headers (OTA phase C, C0.5)

The C0.5 seam edits `scripted-rpc-transport.ts` and `run-recording.ts`, both
inside `RECORDER_DIRECTORY`, so `recorderSha256` moves and every golden's header
names an engine that no longer exists. `baseline` moves with it, from
1e3795de99 to ddbb194585, which is main's tip and the tree these were recorded
against; the recorder's fence is clean at that commit, tracked and untracked
alike.

Recorded whole rather than in part, as the README requires: a partial refresh
would leave the corpus pinned to two different trees.

The delta is header-only, and that is checked rather than asserted. All 787
goldens changed exactly two lines each, and across the corpus and the manifest
the only keys that moved are `baseline` and `recorderSha256`, to one value
each. No observation moved, which is the claim the pair of digests exists to
make: the engine changed, what it observes did not.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): correct the bridged-parity counts to what the landed tree measures

The counts in the harness's header were read off an intermediate run: 391 is
the divergence with the reply schema's `_meta` requirement already widened, not
the divergence this tree has. Against the tree as it lands, 763 of 787 goldens
diverge and 24 replay byte-identically; widening `_meta` is worth 372 of them
and takes the count to 391.

The same intermediate run is behind a wrong sentence in this lane's first
commit message, which says no sender ordinal moves with the instrumentation
above the seam. Seven do, plus six payload ordinals, and they are the subscribe
reorder cause 3 now names. 131 was the count below the seam.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repartition the bridged-parity classes from a measured run

The header's last two counts were read off an intermediate measurement. Classified
from the failure text of a run with the `_meta` arms widened, the 391 that remain
partition 345 / 33 / 13, not 340 / 13, and the ordinal class is not a reorder on the
wire: the page posts its frames in call order and they publish in that order, while
the writes the operation makes above the bridge land a delivery earlier.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): let the shared bridge port pair carry any shell client

The golden recorder needs the pair the bridge tests already have, holding its own
scripted client rather than the fake, delivering the handshake in place so a screen
can mount in the same turn, and able to answer one counterfactual: what the page
would have done had the shell posted a field it does not. Every other test keeps the
shape it had under `createFakeBridgePortPair`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): catch a wrapper that swallows a send instead of mislabelling the next

The seam took the next name off the queue without checking it belonged to the method
now on the wire, so a wrapper that rejected without forwarding left its name behind
and the following payload was filed under it. Underflow already threw; this is the
other half, and it is the half that is silent.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the bridged-parity partition by rule instead of by reading it

Counting the classes by eye is how two of them drifted. Every diverging golden is now
named by a rule over the frames and the scenario, each name is disjoint, and a golden
that fits none of them fails the run. The first class needs a second replay with
`_meta` supplied, because nearly every golden is refused some reply for that field
and only supplying it says which ones the field explains: 372 / 338 / 7 / 33 / 13
over 787, with 24 byte-identical. CI runs it so the counts cannot drift again.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): repin the recording corpus and refresh its headers

The seam's name check and the export the parity suite reads both sit inside
`recorderSha256`, and the port pair the suite now borrows sits inside the recorder's
fence, so the pin moves to this branch's tip and all 787 headers follow. Two lines per
golden, both of them header: baseline and recorderSha256, and no body byte anywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the recorder's own boundary ratchets green

Two of them were red, and the first has been since the seam landed, because that
commit was checked against the recorder's directory instead of the whole mobile
suite. The engine may not import a suite, so the parity classifier moves beside the
recorder rather than inside it, where the golden digest would also stop claiming a
recording's provenance for a rule that only reads failures. And the raw-port ceiling
for the scripted transport rises from five to seven: the seam needs one layer between
the operation's call and the logical client, and its two references are what that
layer costs. A named argument type takes back the third.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): repin the corpus onto the ratchet fixes and refresh its headers

Supersedes the refresh two commits back: the scripted transport moved again, so both
the digest and the pin do. Two lines per golden, both header, no body byte anywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stamp the counterfactual on replies only, not on events

An `event` frame carries a `payload` too, so keying off the key rather than
the type put `_meta` into subscription bytes. The page reads an event payload
as `z.unknown()`, so nothing refused it and the classes did not move, but the
tool that names a divergence must not author one.

Jinwoo Hong ddbb194585 feat(mobile): page-side RpcClient over the web shell bridge (OTA phase C, C0.4) (#21467)
* feat(mobile): RN bridge host for the web shell page (OTA phase C, C0.3)

One page document's end of the bridge: page frames in through the C0.1
reader, one RpcClient behind it, host frames out. Requests forward with the
arity the page used and answer with the verbatim RpcResponse, chunked when it
is over the frame cap; a rejection crosses as the five-field capture instead.
Subscriptions carry a seq and an unacked window, and end with `overflow`
rather than dropping frames a reader cannot see are missing.

The fence is structural: the protocol names no host, so the client is
whichever this host was built with, and the in-flight caps the page is told
about in `init` are enforced here rather than trusted from there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): wire the bridge host to B4's hybrid shell screen (OTA phase C, C0.3)

The channel opens on the session B4 put on screen and closes with it. The
session id is B4's: nothing new is minted, and a remount is a new one, which
is what makes a dead page's frames fail the native origin check.

Both halves are stamped with the session they belong to, because React swaps
refs during the commit and runs the retiring effect's cleanup after it — a
host disposing on a remount would otherwise post its teardown into the page
that replaced it. `bridgeEnabled` is derived from the session step alone,
since the native side treats a prop change as a reload.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove the bridge fence holds for traffic, not just for answers

A mutation that dropped the post-teardown guard in `receive` survived: the
teardown case only fed a frame whose answer the outbound guard already
swallowed, so nothing observed that a dead page could still reach a live
client. Both teardown paths now feed a request, a subscribe and a notify,
and assert the client saw none of them.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): read the hook's frames through the page's own reader

`JSON.parse` returns `any`, and taming it with an assertion is a cast the
gate refuses and a check nobody gets. Reading each posted frame through
`readBridgeHostMessage` types it and proves the same thing the host's own
suite does: a frame the page would refuse is a frame that never arrives.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): list the bridge host as a raw request port owner

The boundary ratchet reads a `.sendRequest` access as a call site, and the
host has three: one per arity the page can use. It is not a call site. It
picks no method, reads no reply and decides no acceptance — the page names
the method and runs the typed operation over the client this carries, which
is what the C0 design put page-side so `runRpcOperation` stays unchanged
there. That makes it an owner, beside the socket and relay senders, not a
migration backlog entry.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): page-side RpcClient over the web shell bridge (OTA phase C, C0.4)

Every member of the native contract, carried over the C0.1 envelope so the
screens above it cannot tell a bridge from a socket: requests keep the arity the
caller used, a host RpcFailure resolves as data while a rejection is rebuilt with
its class and its delivery-unknown mark, subscriptions stream with periodic acks,
and the synchronous getters read a cache primed by init rather than answering
before they know.

A state whose generation went backwards is refused and re-asked for, because a
shell rebuilt under the page makes what the page holds the newer of the two.
close settles what the page owns and never touches the shell's client, which the
native screens and the host catalog still share.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): run the page client against the shell host over an in-memory port pair

One FIFO per direction and delivery on a microtask, which is what C0.5's golden
replay needs: a subscribe that overtook a sendRequest would move the recorder's
shared ordinal, and anything stronger than a microtask moves a virtual
millisecond. Every member round-trips through the real host over a fake client;
the frame-level suite covers what no pair can reach, including the handshake
backoff, refusals and the binary lane C6 will fill.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): list the page bridge client as a raw request port owner

Both ends of the bridge hold the port as a transport: one forwards raw requests
and the other offers them, and neither picks a method or reads a reply.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the assembler discard no abandoned request can reach

A request is only abandoned when its frame never left the page, so the shell was
never told the id and no part can have arrived under it. Says what actually keeps
an omitted param omitted while it is here: JSON drops an undefined value, so the
spread states the intent rather than producing the result.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): close the three gaps a mutation sweep found in the page client

A settled id has to give its assembler slot back, or 64 replies that were cut
short before an error leave the page unable to read the next chunked one. Close
says goodbye once rather than cancelling each stream first. And the read guard is
only observable through a port that ignores its own unsubscribe, which is what
the harness can now be.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove a stream that overflows inside subscribe is unsubscribed

A client that emits synchronously from `subscribe` can retire a stream before
its unsubscribe exists to be stored. The identity check that calls it instead
had no test; deleting it left the suite green while the client's stream leaked.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hand the bridge host over in the commit, not after it

A client swap that keeps the session id leaves the handler's own fence inert:
until the passive effect ran, a native frame reached the retiring host and the
client it closed over. A layout effect swaps both inside the commit.

Teardown on unmount now runs while the view is still attached, so a pending
request is answered delivery-unknown instead of being dropped on the floor.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold a refused page frame to one warning per page

A page that sends one bad frame usually sends many, and a line each buries the
first — the one that says why. Same bound the host already keeps on a failing
post, applied per kind and reset when a new page gets a new host.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): bound the page's terminal viewport at the bridge contract

A viewport crossing the bridge is written into the cached subscribe params of
every stream naming that terminal, including the native terminal screen's, and
the desktop refuses cols over 1000 or rows over 500 when those streams
resubscribe. Unbounded, one page could kill streams it never opened; the frame
is refused instead, and the bound is pinned to the desktop's own.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop the page's close from latching the bridge host shut

One view carries every document the shell loads, so the page that says `close`
is not the last one. A latched host dropped the next document's `ready` in
silence, and a page that re-sends `ready` on a backoff would retry forever with
nothing posted and nothing logged. Close now cancels what the page owned and
leaves the host live; only dispose shuts it, and a frame arriving after that is
diagnosed rather than dropped.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a throwing client or post inside the bridge host

The `state` frame is sent from inside the client's own state-change fan-out and
a notify runs on the native event handler that delivered the page's frame, so a
synchronous throw from either escapes into a loop the bridge does not own and
takes unrelated listeners with it. Both are fenced and reported once.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove an ack releases the stream's unacked bytes

The frame window reopens on ack through the splice, so deleting the byte
release left every existing test green while a long-lived stream of large
frames would end with overflow on its first frame after an ack.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): pass the commit-window harness its children as a prop

`createElement`'s variadic children do not satisfy a props type that declares
`children`, so the file dropped out of the tests typecheck ratchet.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): render the harness from the commit-window wrapper, not as children

A props type that declares `children` is what `createElement`'s variadic form
does not satisfy, and passing it as a prop instead trips the react rule. The
wrapper renders the harness itself, which is the parent position the layout
effect ordering needs anyway.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): pin the desktop viewport bound by reading it, not importing it

Mobile may not pull an rpc-contract *value* into its bundle, and the boundary
test that enforces that scans this test file too. The pin reads the schema's
own source instead, so drift in either bound still fails loudly.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): settle a refused subscribe as the stream it was

The shell answers a refused `subscribe` with `error` on the stream's id.
Routing that to the pending requests dropped it, because no request is
open under that id: the page heard nothing and kept the slot forever.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): report a reply or an error the page has no id for

Silently dropped before. Nothing recovers it in place, but a frame the
page cannot place means the two ledgers disagree, which is worth a line.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): say disconnected on close instead of going silent

Every native client publishes the transition and keeps answering its last
snapshot; the screens read both. The page's client cleared the cache
instead, so a closing page left its listeners on a dot that never moved
and every getter throwing underneath it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let a closed page client go inert, not throw

An unmounting screen still calls, and nothing on a teardown path catches.
Subscribe hands back a no-op dispose and the notifies do nothing, as the
native client's do, and a request rejects rather than throwing past the
caller's catch. A call before init still throws: that one is a bug.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): lift the init handshake out of the page client

The backoff that asks the shell for a session is its own concern, and the
client had grown past the file's line budget holding it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the cancel a page owes for a stream already ended

A screen unmounts on its own schedule, routinely after the shell gave up
on the stream. Only the double-dispose order was covered.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state what the page client does after close

The doc gave the pre-init rule and stopped; the after-close rule is the
opposite one, and subscription failures have no channel but a diagnostic.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): read the shell's page channel as a client transport

The document-start installer leaves `postMessage` and one `onmessage`
slot, the intersection of what the two platforms inject. A page opened
outside the shell has no global at all, so reading it answers null rather
than throwing: the bundle still has to open in a browser.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): give the page its bridge client instead of a placeholder

The web provider now builds BridgeRpcClient over the shell channel and
mounts nothing until `init` lands: every member throws before a session,
and a screen that rendered first would record its first frame against a
client that has none. Outside the shell there is no session coming, so
the placeholder stays and the route tree mounts at once, which is what
the Route A render check exercises.

* fix(mobile): serve the bridge to one document at a time

A page's `close` now ends that document's turn: until the next `ready`
claims the view, every other frame is dropped and diagnosed instead of
reaching the client, and nothing is posted. Without the fence a straggler
from the closed document was still forwarded, and a `state` frame from the
still-running client landed in the replacement document before its `init`.

* fix(mobile): hold the request cap against the calls, not the page's ledger

`sendRequest` has no cancel, so a request the page cancelled or closed out
keeps running on the desktop until it answers. The cap now counts those
calls until each settles; counting the pending map let a page interleaving
`close` with batches hold many more than the cap `init` advertises.

* test(mobile): pin the ack ratio to the shell's window, not a copy of it

The ack interval test held 256 and 4 MiB as literals, so narrowing the
shell's window would have left the page acking too late with the test still
green. The comment naming the test that pins the ratio pointed at the wrong
file.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give back the slot of a subscribe that never left the page

A post that threw left the stream in the page's ledger with nothing open on
the shell's side, so 32 of them exhausted the subscription budget for the
life of the document. The slot goes back and the listener hears a terminal
error result, which is what the native client does with the same failure.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): end a page stream through its listener, not only the log

A stream the shell ends or fails now reaches its listener as a terminal
error result, the way the native client's emitError does. A consumer reads
that result: host-worktree-refresh clears the flag that says the event
stream is live, and without it the worktree list stops updating for the life
of the document. A dispose the page asked for stays silent.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): settle the old shell's work before adopting a new session

A second `init` naming a different sessionId is a rebuilt host with empty
tables: every pending request and every open stream the page still held
belonged to the shell that is gone. They now settle delivery-unknown and end
through their listeners before the new session is adopted. A second `init`
for the same session is what a re-asked `ready` earns, and keeps everything.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): take the page's streams out of the ledger before failing them

A listener that resubscribes while the old shell's streams are being ended
is opening one against the shell that is arriving; draining the map first is
what keeps this loop from tearing that one down too. Fixes the lint the
previous commit left behind.

* docs(mobile): say how long a reply assembler's refusal actually lives

The tombstone is not kept forever: the request ledger discards the id as it
settles the caller, so it normally outlives only the rest of the reply that
raised it. The bounded map is there for the ids nothing settles.

* docs(mobile): say why the document fence carries no epoch

Page frames reach the shell through one native listener per platform, so a
straggler from the closed document lands before the next document's `ready`
and the flag alone catches it. An echoed epoch would be a wire change for
nothing.

Jinwoo Hong f2be6299c8 feat(mobile): RN bridge host for the web shell page (OTA phase C, C0.3) (#21459)
* feat(mobile): RN bridge host for the web shell page (OTA phase C, C0.3)

One page document's end of the bridge: page frames in through the C0.1
reader, one RpcClient behind it, host frames out. Requests forward with the
arity the page used and answer with the verbatim RpcResponse, chunked when it
is over the frame cap; a rejection crosses as the five-field capture instead.
Subscriptions carry a seq and an unacked window, and end with `overflow`
rather than dropping frames a reader cannot see are missing.

The fence is structural: the protocol names no host, so the client is
whichever this host was built with, and the in-flight caps the page is told
about in `init` are enforced here rather than trusted from there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): wire the bridge host to B4's hybrid shell screen (OTA phase C, C0.3)

The channel opens on the session B4 put on screen and closes with it. The
session id is B4's: nothing new is minted, and a remount is a new one, which
is what makes a dead page's frames fail the native origin check.

Both halves are stamped with the session they belong to, because React swaps
refs during the commit and runs the retiring effect's cleanup after it — a
host disposing on a remount would otherwise post its teardown into the page
that replaced it. `bridgeEnabled` is derived from the session step alone,
since the native side treats a prop change as a reload.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove the bridge fence holds for traffic, not just for answers

A mutation that dropped the post-teardown guard in `receive` survived: the
teardown case only fed a frame whose answer the outbound guard already
swallowed, so nothing observed that a dead page could still reach a live
client. Both teardown paths now feed a request, a subscribe and a notify,
and assert the client saw none of them.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): read the hook's frames through the page's own reader

`JSON.parse` returns `any`, and taming it with an assertion is a cast the
gate refuses and a check nobody gets. Reading each posted frame through
`readBridgeHostMessage` types it and proves the same thing the host's own
suite does: a frame the page would refuse is a frame that never arrives.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(mobile): list the bridge host as a raw request port owner

The boundary ratchet reads a `.sendRequest` access as a call site, and the
host has three: one per arity the page can use. It is not a call site. It
picks no method, reads no reply and decides no acceptance — the page names
the method and runs the typed operation over the client this carries, which
is what the C0 design put page-side so `runRpcOperation` stays unchanged
there. That makes it an owner, beside the socket and relay senders, not a
migration backlog entry.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove a stream that overflows inside subscribe is unsubscribed

A client that emits synchronously from `subscribe` can retire a stream before
its unsubscribe exists to be stored. The identity check that calls it instead
had no test; deleting it left the suite green while the client's stream leaked.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hand the bridge host over in the commit, not after it

A client swap that keeps the session id leaves the handler's own fence inert:
until the passive effect ran, a native frame reached the retiring host and the
client it closed over. A layout effect swaps both inside the commit.

Teardown on unmount now runs while the view is still attached, so a pending
request is answered delivery-unknown instead of being dropped on the floor.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold a refused page frame to one warning per page

A page that sends one bad frame usually sends many, and a line each buries the
first — the one that says why. Same bound the host already keeps on a failing
post, applied per kind and reset when a new page gets a new host.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): bound the page's terminal viewport at the bridge contract

A viewport crossing the bridge is written into the cached subscribe params of
every stream naming that terminal, including the native terminal screen's, and
the desktop refuses cols over 1000 or rows over 500 when those streams
resubscribe. Unbounded, one page could kill streams it never opened; the frame
is refused instead, and the bound is pinned to the desktop's own.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop the page's close from latching the bridge host shut

One view carries every document the shell loads, so the page that says `close`
is not the last one. A latched host dropped the next document's `ready` in
silence, and a page that re-sends `ready` on a backoff would retry forever with
nothing posted and nothing logged. Close now cancels what the page owned and
leaves the host live; only dispose shuts it, and a frame arriving after that is
diagnosed rather than dropped.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a throwing client or post inside the bridge host

The `state` frame is sent from inside the client's own state-change fan-out and
a notify runs on the native event handler that delivered the page's frame, so a
synchronous throw from either escapes into a loop the bridge does not own and
takes unrelated listeners with it. Both are fenced and reported once.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove an ack releases the stream's unacked bytes

The frame window reopens on ack through the splice, so deleting the byte
release left every existing test green while a long-lived stream of large
frames would end with overflow on its first frame after an ack.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): pass the commit-window harness its children as a prop

`createElement`'s variadic children do not satisfy a props type that declares
`children`, so the file dropped out of the tests typecheck ratchet.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): render the harness from the commit-window wrapper, not as children

A props type that declares `children` is what `createElement`'s variadic form
does not satisfy, and passing it as a prop instead trips the react rule. The
wrapper renders the harness itself, which is the parent position the layout
effect ordering needs anyway.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): pin the desktop viewport bound by reading it, not importing it

Mobile may not pull an rpc-contract *value* into its bundle, and the boundary
test that enforces that scans this test file too. The pin reads the schema's
own source instead, so drift in either bound still fails loudly.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): serve the bridge to one document at a time

A page's `close` now ends that document's turn: until the next `ready`
claims the view, every other frame is dropped and diagnosed instead of
reaching the client, and nothing is posted. Without the fence a straggler
from the closed document was still forwarded, and a `state` frame from the
still-running client landed in the replacement document before its `init`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold the request cap against the calls, not the page's ledger

`sendRequest` has no cancel, so a request the page cancelled or closed out
keeps running on the desktop until it answers. The cap now counts those
calls until each settles; counting the pending map let a page interleaving
`close` with batches hold many more than the cap `init` advertises.

Jinwoo Hong 381a3da46f feat(build): Route A, the phone's host routes bundled for the web, dark (OTA phase C, C0.7) (#21449)
* refactor(mobile-web): share the bundle manifest assembly with a second builder

Manifest assembly and the on-disk write move to writeMobileWebBundleTree, and
the helpers the Phase C app builder needs become exports. No behaviour change
to the shipped bootstrap bundle.

The CRLF guard grows two exemptions it needs once it is pointed at mobile/src:
the image and font extensions .gitattributes already pins -text, and the
gitignored webview engine modules the postinstall writes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): web entry for the host route tree, and its two transport siblings

The entry mounts app/h on react-native-web through expo-router's own ExpoRoot.
It lives inside mobile/ so one React resolves, and supplies RpcClientProvider
itself: the route tree starts below the native root layout that owns it.

route-manifest.ts is a real typed module whose body the builder replaces --
esbuild has no require.context. A virtual specifier would need an ambient
declaration and would leave the entry unchecked.

Two .web.* siblings, both listed with a reason in web-overrides.json: the
transport substitution point (a placeholder client until C0.4 lands
BridgeRpcClient) and the device token store, whose native path imports
expo-secure-store, which is {} on web.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(build): build:mobile-web:app, the phone's host routes bundled for the web

Same builder shape as the Phase A bootstrap into a separate out/mobile-web-app,
with the same manifest and the same two-scratch-build determinism check. Dark:
build:mobile-web, packaging and the A2 census are untouched, and C1 is what
flips build:release.

Six shims, each a named Metro or RN Web gap. Images are emitted as same-origin
hashed assets rather than data: URLs, because the shell's CSP sets img-src
'self'; the render check under that exact header is what found it. The script is
referenced root-absolute for the same reason a <base> tag cannot be used: the
document is served at every route depth and base-uri is 'none'.

The budget sits below the contract's per-asset ceiling so growth trips a build
rather than a refused asset on a phone. esbuild splitting does not lower it:
one entry with only static imports emits one chunk (measured).

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let React Native Web paint under the shell CSP

RN Web 0.21.2 injects its stylesheet at runtime with no nonce support, so
style-src 'self' blocks every rule and the page renders unstyled. Measured, not
predicted: the render check serves the document under this exact header and
reported the violation.

'unsafe-inline' is granted to style-src and nothing else. script-src 'self'
holds, which is the directive that decides whether page code can arrive any way
other than as a fetched same-origin script. The test now pins that scoping
rather than rejecting the token everywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* ci: prove the Route A app bundle on every PR

A dedicated job, for the same reason the browser provider has one: it needs
mobile/node_modules and a real browser, and the sharded test matrix would pay
for both on every shard. It builds the bundle, verifies it, and runs the
builder, override-census and render suites. It ships nothing.

The mobile_web_app signal is lifted out of should_run the way static_analysis
is. A mobile-only diff is desktop-irrelevant and skips every gated job, and
that is exactly the diff that changes the page this job builds.

Also the C0.6 review follow-up: mobile/package.json and mobile/pnpm-lock.yaml
join the installer cache keys in the two workflows that build an installer off
a hashFiles key, since beforePack requires out/mobile-web and a mobile-only
change must miss those caches rather than reuse a stale build.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): pin the shipped builder against the app builder's own module name

The assertion named a specifier that no longer exists, so it held vacuously.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): assert the RN Web style-src grant in the Swift checks

The Swift twin of the Kotlin CSP test still required style-src 'self' and
no unsafe-inline anywhere, so it trapped on the approved grant.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): make the Route A render check name what each route paints

The check asserted only "some html, no errors", which expo-router's Unmatched
screen satisfies: pointing HOST_ROUTE at /zzz/not-a-real-prefix stayed green.
Each route now asserts content only its own component produces, and the
unmatched case asserts the screen positively so the negatives discriminate.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): read the shell CSP past the comments that quote directives

Both constants document themselves with // comments containing quoted
directive text, which the quoted-string scan picked up as directives. One
parser now drops comment lines, and iOS and Android go through it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(build): honour a .web.* route sibling in the app bundle

Routes were imported by absolute path with the extension, so esbuild's
resolveExtensions never applied and a .web.tsx under app/ was dead code the
census still accepted. The manifest now carries a key and a module: the key
stays the native filename so the URL does not move, and the module is the web
sibling when one exists.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): tie each named shim to the esbuild option that implements it

The shim list was asserted against a literal copy of itself, which passes
however the build is configured. Each entry now carries an appliesTo that
reads its own option, checked against the real options object.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(build): line up the CRLF exemptions, the budget comment, and the job scope

The builder loads .gif as a file but neither .gitattributes nor the CRLF scan
exempted it, so the blanket eol=lf pin would have rewritten one. A test now
keeps the two lists in step. The Phase C byte budget's comment sat on the
asset count, and a root package.json edit could change build:mobile-web:app
without running the job that proves it.

* ci: key the installer caches on the mobile page trees too

beforePack builds the mobile web bundle into the installer. Today those bytes
are Phase A's, which src/** already covers, but once C1 flips the entry to
mobile/app a page-only change would hit a cache holding a stale installer.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): skip the bundling tests where mobile dependencies are absent

The sharded `test` job collects config/scripts/**/*.test.mjs and installs no
mobile dependencies, so the two new suites failed there on "Could not resolve
react-native-web". They now skip themselves with a message naming the job that
runs them, and that job sets ORCA_MOBILE_WEB_APP_DEPS_REQUIRED so a missing
install fails it instead of skipping everything it exists to prove.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(build): scan mobile/packages in the .web.* census

The census claimed the app entry never resolves into packages/, but the
dictation hook imports @orca/expo-two-way-audio and the built script carries
ExpoTwoWayAudioModule.web.ts. That file is now listed with its reason, and
planting a .web.* in each scanned tree proves the scan is not passing because
a tree happens to be empty.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): assert the route exclusions against a tree that has them

mobile/app holds no test, spec or +api file, so the exclusion rule was
asserted against a tree it could not fire on. A scratch tree plants one of
each; dropping the rule now fails this test.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): 404 unknown file paths in the render check's page server

The server answered every path with the document, so pointing publicPath at
/wrong-prefix still rendered three green routes: the script is fetched from
the one prefix that is served. A path naming a file now has to come out of the
bundle, which is what the shell's manifest map does.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): cover the app bundle verifier's own checks

The verifier had no test. One doctors the buildId, which the packaged assert
catches; the other rewrites the tree so every digest still agrees and only the
two fresh builds can tell, which is what a stale out/ looks like. Deleting
either check now fails a test.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* chore(build): tidy the app bundle comments and the job's path prefixes

Drops an export nothing read, merges two comments that had drifted apart from
the constant they describe, and corrects the claim that the job runs on every
PR when it is path-gated. package.json leaves the prefix list because
GLOBAL_FORCE_FILES already forces every job on it; mobile/packages/ joins it,
since the page resolves a .web.ts out of there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): redirect the hybrid shell route on the web page

app/h/[hostId]/web.tsx reaches OrcaMobileWebShellView, whose module calls
requireNativeViewManager at import. In a browser that throws before React
mounts, and the route manifest imports every route statically, so one native
route left the whole page blank at every URL.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): fail the render check with the error that stopped the mount

The check waited on "#root has children" with Playwright's animation-frame
polling, so a route module that threw at import read as a bare 30s timeout
naming nothing. It now waits on a mount attribute the entry sets after the
router commits, polls on a timer, and races the wait against the first
uncaught error so the failure carries it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): answer the favicon the render browser asks for

CI resolves the runner's Google Chrome, which requests /favicon.ico; the
bundled headless shell does not. The bundle carries no icon, so the server
answers 204 rather than turning a browser habit into a console error the
render assertions read as a page fault.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): settle the render check's uncaught-error race without rejecting

The entry throws during goto, before anything awaits the race, so a rejected
promise surfaced as an unhandled rejection beside the real failure. The same
signal now resolves with the error.

Jinwoo Hong 47d107cf2e feat(mobile): hybrid shell route, dark behind a dev-only flag (OTA phase B, 4/4) (#21435)
* refactor(mobile): say whether a host status was readable, and carry its protocol window

`useHostStatusGates` settled the same closed gates for a host that answered
`status.get` with no capabilities and for one whose status nobody could read:
both paths produced an empty capability list and an `ok` verdict. A caller that
walls on a missing capability cannot tell those apart, and the mobile web
bundle's wall is terminal, so it must never fire for the second.

`statusReadable` distinguishes them. `hostProtocolWindow` exposes the two
protocol numbers the hook already read for `evaluateCompat`, as the reply's own
fields, so the bundle wall can evaluate its own window without a second
`status.get`. Both are additive; no existing consumer changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): add the hybrid shell flag and the generation path both loaders demand

`orca:mobileWebShellEnabled`, default off and unreadable-is-off, in the same
shape as the terminal autocomplete flag.

`generationDirectoryPath` converts the store's `file://` uri to the absolute
path the native shell view requires: both `MobileWebShellGeneration.load`
implementations refuse anything without a leading slash, and `expo-file-system`
only ever hands out uris.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the hybrid shell session as a pure reducer

Every decision the route makes, as `(session, event) -> (state, effects)`: the
capability wall, the lazy sweep and cache read, the manifest check, the cached
build-id hit that skips paging, the offline open with no compat check, and the
three recovery rules the native shell view's contract states.

Pure, so the rules are table tests rather than a simulator run. Two latches sit
beside the state because both outlive it: `retriedOnce` spans the delete and
refetch that returns to `checking`, and `remountedOnce` spans a `ready` replaced
by a `ready` under a new session id.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): the hybrid shell route, dark behind a dev-only flag (OTA phase B, 4/4)

Wires the four Phase B and A pieces together and adds no decision of its own.
`h/[hostId]/web` sits inside the existing `HostProtocolGate` tree, so the native
`desktop-too-old` wall still applies above it. With the flag off — every store
build, since the only writer is a `__DEV__` Troubleshoot toggle — the route
redirects to `h/[hostId]` and the screen is never constructed, so nothing is
fetched, written or swept.

The runner owns only the impure edges and checks an epoch before every dispatch,
so an unmount, a host change or a retry abandons work in flight and aborts a
download that would otherwise hold four of the host's read slots. The native view
is keyed on the session id, which is what makes the reducer's remount a rebuilt
WebView with every fence reinstalled.

A census test pins who touches the flag: the route reads it, the developer row
reads and writes it, and the key itself lives in one module.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): type the hoisted test doubles instead of asserting them

The changed-code casting gate refuses `as` in new code, and these three were

* fix(mobile): read a scheduled reconnect as an unreachable host, not a dial in progress

Found on a simulator with the paired desktop stopped: the client never settles
on `disconnected`. It dials, fails, schedules a retry, and cycles `connecting`
-> `reconnecting` -> `connecting` with the delay growing to a minute. Mapping
`reconnecting` to "still connecting" left a phone holding a verified cached
generation on `checking` forever instead of opening it, which is the one case
the offline rule exists for.

`connecting` and `handshaking` are the first dial and still wait; everything
else is unreachable. The mapping moves next to the reducer it feeds, because it
is a decision and the runner is supposed to hold none.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): build the reachability stub instead of asserting it

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): move the shell session vocabulary into its own module

Pure move, no behaviour: the states, events, effects and gates the reducer
and its runner share now sit beside the reducer rather than inside it, so
the transition rules have room to grow under the file's line budget.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): drop a shell effect result whose flow has been superseded

Every restart of the flow bumps a number the effects of that run are stamped
with, and a result echoes it back: a manifest read still in flight when the
socket drops used to reject after the offline path had already opened the
cached generation, replacing a displayed workspace with a download failure,
and a status refetch arriving mid-check used to run the cache read and the
download twice. The gates restart no longer clears the remount latch either;
only the retry button does, so a reconnect cannot grant a second remount.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): census the flag across modules, not just src and app

The native view tree was outside the scan, so a reader added there would
have passed an assertion that reads as exhaustive. Proven by adding one to
the shell view module: the census fails.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let only the state that mounted the view hear the view

A native batch reports two failures in a row, and the reducer applied both:
document-load-failed started the delete-and-refetch, render-process-gone
then made it terminal without a new flow, and the cache read the recovery
had already asked for dragged the session back to checking behind a failure
screen. A report arriving outside `ready` is from a view that is no longer
on screen, so it changes nothing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): say a host status could not be read instead of spinning on it

A transient status.get failure settles the gate unreadable and nothing probes
it again, so the route sat on "Checking host" for as long as anyone left it
there and Try again re-read the same settled answer. It now says what
happened and offers no retry, and a status that does become readable picks
the flow back up on its own.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): restart the flow on the verdict that changed, not on every gates object

A reconnect cycle rebuilds the gates several times a second with the same
answer in them, and each one re-swept the staging tree and flipped an offline
screen to a spinner and back. Only a changed verdict restarts now, which is
also why the gates effect has to depend on the host id: two hosts whose gates
read identically would otherwise leave the second session in `checking`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): cover what only the shell runner can get wrong

Three cancellations had no test: the epoch that stops a result reaching a
session that is gone, the unmount cleanup that aborts the download, and the
retry that does both before starting over. Each is now red under its own
mutant. The download also re-checks the abort before it writes, since an
abort landing between the fetch's last read and the commit would otherwise
still put a generation on disk for a screen nobody is on.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): write the shell runner's refs after the commit, not during render

React can replay or discard a render, so a handle written during one can run
effects for a session that never existed. The client and the host cache key stop
being refs at all; the effect handle is committed in an effect above every
effect that dispatches.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the hybrid shell flag unreadable outside a development build

Development and release share a bundle id, and the iOS data container survives
an install-over, so a flag a developer toggled on would follow the store build
in and mount the shell on a deep link. The release read never reaches storage.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): drive the route's flag read as each build kind reads it

The route test exercises the real preference read, so it has to say which build
it is. A store build whose container kept a development toggle redirects.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let a cache read that lands mid-dial wait for the compat check

A connection still being made is not a host that cannot be reached. Opening the
cached generation there skips the compat check the landing connection is what
makes answerable, so only `unreachable` takes the offline path now.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): move the developer toggle only after its write lands

The route reads the flag back from storage, so a switch that moved on the tap
let the open button race the value that was being persisted. The switch and the
button both stay put until the write settles, and a failed write keeps the
previous position.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): say which build kind a test runs as without asserting on globalThis

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): undo a staged generation the abort reached before the commit

The commit is the write staging cannot take back: it renames into the active
slot and moves the host index. An abort landing while the bytes were being
staged now removes the staged tree instead of activating it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): open the cached workspace when the link, not the bundle, cut a read short

An RPC rejection can reach the reducer before the reachability change does, so
the offline gate never fires and a phone holding a valid generation reads that
the workspace could not be downloaded. A read that failed on the link now opens
what is on disk, the same path offline takes; a verdict about the bundle, from
the host or from the bytes, still fails.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): send a hybrid shell recovery through the same gate a start takes

A view failure deleted the host cache and went straight back to the manifest
check on whatever gates the ready session happened to be holding. Gates that
arrive while a generation is on screen are stored without restarting, so after a
reconnect whose status probe failed a ready session carried statusReadable false
and an empty capability list, and the recovery's manifest check walled the host
as bundle-unavailable: terminal, no retry, about a host that never answered.

The gate is now one verdict both entries read, and recovery passes its delete
through it, so an unreadable status lands on the status-unreadable message that
re-arms when a readable gate arrives, and only a readable refusal still walls.

Jinwoo Hong 8fc81182ab feat(mobile): envelope contract for the web shell bridge (OTA phase C, C0.1) (#21432)
* feat(mobile): bound a web-shell bridge frame at one enforcement point

The page and the shell exchange frames over a native channel that will happily
carry whatever either side hands it. `parseBridgeMessage` is the only place the
byte, depth and node caps are checked, and the byte cap is checked against the
raw string so it protects `JSON.parse` rather than trusting it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): carry a bridge rejection without losing its delivery-unknown mark

A host `RpcFailure` is data and rides in the reply untouched; a rejection of
`sendRequest` is the other path and needs rebuilding page-side. The mark that
says the request may already have run is a `WeakSet` on object identity, so it
cannot survive serialization and has to be re-applied, and the recorder reads
`error.constructor.name`, so the rebuilt error is named rather than plain.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): declare every message the web shell bridge carries

One schema per message in both directions, with `v` gating envelope shape and
`init.grants` gating capability. Unknown keys are dropped rather than refused:
the page bundle ships from a desktop that updates independently of the installed
shell. A reply payload is read through loose objects so a field a newer host adds
reaches the page unaltered, which is what the goldens record.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): split an oversized bridge reply instead of refusing it

The native screens have no reply byte cap, so refusing one at the frame cap would
invent a failure the phone does not have; source control's diffs would be first
to hit it. Frames are measured after serialization and only then accepted, so an
escaped control character or a surrogate pair cut across the boundary cannot push
one over. The absolute ceiling aborts the request rather than truncating a reply.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the bridge numbers rather than deriving every fixture

A test that builds its fixture from the constant it is checking moves with that
constant: widening the frame cap, the depth, the node count or the reply ceiling
left every boundary case passing. These numbers are wire between a released shell
and a page served by a desktop, so they are pinned as literals; the in-flight and
subscription caps had nothing holding them at all.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): bound the page's frames, not the desktop's answers

The depth and node caps exist to bound the cost of walking a hostile frame,
and only one direction is hostile. A 5 000-row listing reply carries 25 000
values, so holding the shell's answers to the same 20 000 node cap would
refuse ordinary data. `parseBridgeMessage` now takes the direction and walks
`page-to-shell` only; both directions keep the frame byte cap, and a chunked
reply keeps the 8 MiB ceiling as its single bound.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): carry a decoded screencast frame, not just its bytes

The binary `event` carried `b64` alone, but a binary listener is handed an
already-decoded `BrowserScreencastFrame`: format, metadata and the
screencast's own frame counter would all have been lost, and the envelope's
`seq` is the backpressure counter, not that one. The frame's fields now ride
beside the base64, mirrored field for field, with a compile-time pin that
nothing but the image is missing. C6 writes the encoder.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): fail to compile when the sender grows an option

The options pin only proved the schema accepts what the sender declares
today. A `Record<keyof SendRequestOptions, true>` makes the other direction
a compile error, so a new option cannot ship past the bridge unnoticed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): carry an error code of any shape, as the recorder does

The capture narrowed `code` to a string or a number, but the recorder
records whatever code it finds. A structured code would have crossed the
bridge as an absent field and moved a golden the day C0.5 replays through
it. Absent still means absent.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): let the schema state the part bound on its own

The splitter's parts-ceiling branch could not fire: the largest reply the
ceiling admits, with every character re-escaping, splits into 26 parts
against a cap of 27. A branch no input reaches is a second statement of a
bound that drifts from the first. The derivation is pinned by a test now,
and `replyPartSchema` is the only place the bound is written.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): bound the ids a reply assembler holds at once

Nothing expired a half-assembled reply, so a host that sent a first part
and never a last one grew the map for the life of the page. A reply exists
only for a request the page made, so the in-flight cap is the right bound,
and the new id is the one refused. C0.4 owes the assembler a discard for
every request it settles.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): refuse a screencast metadata field that is not a number

Only the compile-time pin stood between a metadata field and `z.unknown()`.
Every one of the nine is now exercised, so widening any of them fails a
test rather than only a typecheck.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): survive an error whose own getter throws

Reading `code` and `cause` runs whatever getter defined them, and both were
read in one parse, so a getter that throws took the capture with it: the
rejection path would have thrown where it had to produce an envelope. Each
field is read on its own now, and a throwing getter costs that field only.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a surrogate pair whole across a chunk boundary

A pair cut in half encodes as two replacements, three bytes each, where the
pair whole is four. The sender cut by code unit and the assembler summed the
parts, so a reply within two bytes per boundary of the ceiling was refused
`reply-too-large` for bytes it never had, and each half-pair frame was not
well-formed UTF-8 for the native bridge to carry. The cut backs up one unit,
and the ceiling is measured once on the joined text. Code units still bound
what is held, since a reply is never fewer bytes than code units.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): always produce a capture, whatever the error does when read

`message` and `constructor` can be getters, and `String(value)` runs a
`toString` the thrower wrote, so reading an error is running someone else's
code. A throw there left the rejection with no frame at all and a promise
that never settles. The whole capture is guarded now, and the fallback still
carries the delivery-unknown mark, which is a `WeakSet` lookup.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make an error frame sendable by construction

A megabyte message or code is not a protocol error, it is a big string, and
it produced a frame the receiver refuses as oversized: a rejection the page
never hears. A cyclic code took JSON.stringify down with the whole frame.
Messages are truncated to 16 KiB and marked, a code is dropped when it will
not serialize or is past 4 KiB, and the worst chain the budgets allow now
measures 512 KiB against the 640 KiB frame cap.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a refused reply refused, and bound them together

Every failure dropped the id, so the next part opened a fresh accumulator:
a duplicate part then a whole set completed, and one id could feed 67 MB
through an 8 MiB ceiling one refusal at a time. A refusal is remembered now
and answers every later part, until the page discards the id. The bytes held
across all ids gain a ceiling of their own, since 64 replies at the per-reply
ceiling is half a gigabyte of parts that never complete.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say that a new enum member is not an additive field

The version rule read as though anything additive was safe. A value outside
a closed list is refused whole by the older side, so `end.reason`,
`binary.format`, `connection.state` and the foreground reasons are
negotiated, not appended. The byte-cap comment had its inequality the wrong
way round while I was there.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin what the guards keep, not only what they drop

Two mutants lived: clearing the assembler could have kept its tombstones,
and the guard around a cyclic code was hidden by the outer guard added for
a throwing getter. The capture is now asserted whole, so dropping the code
has to leave the message and the cause behind, and teardown has to forget.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): carry the code that was measured, not the one that made it

A stateful `toJSON` answers the budget check and the frame serializer
differently, so the snapshot is what crosses.

Jinwoo Hong b749091b67 feat(mobile): native shell view serving a mobile web generation from a private origin (OTA phase B, 3/4) (#21417)
* feat(mobile): declare the orca-mobile-web-shell TS surface

Two props and one event: a generation directory the TypeScript store owns, a
session id that scopes the private origin, and a load state. No module
functions and no reload — a retry is a remount under a new React key, which
rebuilds the WebView and reinstalls every fence.

The native event body is a flat dictionary, so parseMobileWebShellLoadState
rebuilds the union instead of asserting it and answers null for anything it
does not recognise.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): serve a generation from a private origin on iOS

A WKWebView behind a custom-scheme handler that answers only from a map built
once from the generation's manifest, with the CSP as a response header on the
document. The scheme handler reads on a serial background queue and keeps a
live-task set that stop() removes from: an asset is up to 10 MiB, and
delivering to a stopped task raises an Objective-C exception Swift cannot
catch.

Origin, request refusal, the manifest map and the policy header hold no WebKit
type, so tests/MobileWebShellChecks.swift compiles and runs them with swiftc,
no device.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): compare the iOS shell's applied props field by field

One joined string could not tell a directory ending in the separator from a
shorter one with a longer session id. Two fields have no separator to collide
on.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin that a string schemaVersion is not a manifest

The contract declares a number. The Kotlin side read it with optInt, which
coerces "1" to 1, so a manifest that widened the field would have been served;
this check covers the same shape on both platforms.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): serve a generation from a private origin on Android

A WebView behind shouldInterceptRequest, answering only from the same
manifest-built map as iOS, with the CSP as a response header on the document.
The origin host label is a slice of the session id's SHA-256, never of the
session id: Chromium lowercases an https host and java.net.URI reads null for
a label holding '_', which is how the reference 403'd every asset.

A main-frame failure is reported from a post() because Chromium commits its
own error document after onReceivedError returns. onRenderProcessGone destroys
the dead WebView and does not rebuild it, so the retry policy stays in one
place. clearCache(true) is never called: it is process-global and would wipe
the terminal WebView's cache too.

* chore(mobile): untrack the shell module's gradle build output

* refactor(mobile): parse the shell load-state payload with a zod shape

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): give the web shell one load-state machine per platform

A failure is terminal, and a repeat says nothing. Chromium commits its error
document after onReceivedError returns and a rule list compiles long after a
generation was refused, so both platforms could report over a failure the
caller had already acted on.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop the Android shell reporting ready over a failed document

onPageFinished ran after reportDocumentFailure's post and both emitted `ready`
and set the WebView visible again, putting Chromium's error page on screen. A
prop change after the renderer died now reports instead of going silent.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): publish the Android shell's served generation atomically

The map and the host it is keyed against were two plain fields written on the

stopLoading on a prop update and every navigation the policy delegate refuses

Jinwoo Hong db2ffe7afe fix(mobile): default injected timers to receiver-free wrappers (#21416)
* fix(mobile): default injected timers to receiver-free wrappers

Every transport class stored a global timer function on an object and then
called it back through that object, so the receiver was the instance or the
dependency bag rather than the global. Hermes ignores the receiver; browsers
reject it with TypeError: Illegal invocation, which makes the web build fatal
at the first retry, liveness probe, or relay grace timer.

Default each injected timer to a wrapper that calls the global receiver-free,
and narrow the seam's type from `typeof setTimeout` to the call signature it
actually uses. Node's `typeof setTimeout` also demands a `__promisify__`
member that no injected timer or wrapper can supply, so the wrapper cannot
satisfy it. Pruning mobile-relay-background-grace.test.ts from the typecheck
baseline follows: the narrower type makes that file check clean.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the default timers against a browser receiver check

Both classes are now constructed with no injected timers under a global
setTimeout/clearTimeout that throws Illegal invocation for any explicit
non-global receiver, mirroring the WebIDL rule. The watchdog gets its own
file because its existing test is grandfathered out of the typecheck ratchet.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove the default clear leg and drop bare timer injections

The clear assertions were vacuous: cancel() and stop() also drop the state a
fired callback checks, so a no-op default clearTimer stayed green. Both tests
now assert the wrapped global clearTimeout received the exact handle setTimeout
returned, which fails when that default is mutated to a no-op.

Three relay tests injected bare setTimeout/clearTimeout into dependency bags,
the same receiver shape the product fix removed; inert under node, fatal under
jsdom. relay-host-signed-out-verdict drops two `as unknown as typeof setTimeout`
casts, since ScheduleTimer now types those arrows contextually.

* test(mobile): census bare global timers parked in properties and defaults

mobile-endpoint-lifecycle could regress to bare globals with every other test
green, because nothing there is reachable from a unit test. Walk every product
file's AST and fail on a global timer parked where a later call reaches it
through a receiver: a `??` or `||` default, an object literal member, or an
assignment onto a property. A plain local capture stays legal, since calling it
bare leaves the receiver undefined.

A separate test asserts the walk sees the five fixed sites' wrapper shape, so an
empty or misdirected scan fails instead of passing vacuously.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): define the receiver-free timer defaults once

Five hand-written wrappers each restated the same invariant, so five places
could drift. timer-scheduler now exports defaultScheduleTimer and
defaultCancelTimer, and carries the reason for them; every site takes its
default from there. The census keys its presence precondition on those two
identifiers instead of the arrow shape.

The census also missed `??=` and `||=`, which park a global exactly like their
non-assigning forms. Both are handled now, with a parsed-source case per parking
form and one for the local capture that stays legal.

Jinwoo Hong 002ff3ddb8 feat(mobile): per-host generation store for the mobile web bundle (OTA phase B, 2/4) (#21409)
* refactor(mobile): export the mobile web manifest read schema

The generation store re-parses the manifest it cached, and it must read it back
with the same loose reader the fetch accepted it under: parsing strictly after
accepting loosely would turn a host's added field into a forced redownload on
every launch.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): add the per-host mobile web generation store

Turns a verified bundle into an atomically activated, host-scoped generation
directory under the OS cache, and reads it back. No RPC, no UI, no flag: the
native view is later handed the directory read-only and never writes to it.

The single directory under `generations/` is the activation, so there is no
activation file to edit: a commit deletes every other generation before the
rename, an interrupted one leaves zero generations for the runbook's redownload
rule, and two directories or an unreadable manifest drop the host tree instead
of guessing. `tmp/` is never an activation candidate and every one of them goes
at launch. `hosts.json` carries recency only, so losing it costs eviction order
rather than a generation.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): never evict the host a commit just activated

`now()` is a wall clock. With four hosts cached, one backward jump made the
fifth commit's own entry the oldest, so it evicted the host it had just
activated and handed back an ActiveGeneration whose directory was gone.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* Revert "fix(mobile): never evict the host a commit just activated"

This reverts commit a082ac1777. That commit carried all six round-1 fixes under
a subject naming only one of them; the six land again below, one per commit.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the generation store's unused eviction entry point

`evictHostsBeyond` had no caller: commit enforces the four-host ceiling itself,
and a launch-time sweep for a shrunk limit can be added when something shrinks
it. The two `createDirectory` calls went with it, since the port already creates
intermediates, plus a line on what the Android rename fallback leaves behind.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): never evict the host a commit just activated

`now()` is a wall clock. With four hosts cached, one backward jump made the
fifth commit's own entry the oldest, so it evicted the host it had just
activated and handed back an ActiveGeneration whose directory was gone.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): fold case when refusing an asset named like the manifest

APFS and NTFS are case-insensitive by default, so `Manifest.JSON` landed on the
store's own `manifest.json` and the activation read back as the asset's bytes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a completed activation when the recency index cannot be written

`hosts.json` is written after the rename, so a disk that filled between the two
turned a generation already on disk into a thrown commit. The index carries
recency, not truth, and the next activation rewrites it whole.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): refuse to commit a staged handle whose tree is gone

Commit deleted every other generation before it looked at the staged tree, so
committing an aborted or swept handle destroyed the live generation and only
then threw. The check moves ahead of the first delete.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): close four surviving generation-store mutants

Sweeping only the first host's tmp, staging over residue, dropping the serial
queue, and dropping the stale-index pruning all passed the suite. The stage
race needed two differing asset lists under one build id to be visible at all:
with identical ones an interleaved pair ends on the same bytes as a serial one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): activate only a build-id entry that holds a manifest

An entry under `generations/` matching the staged build id was taken as the
activation on its name alone, so an empty directory of that name — what a
crash between the rename and the post-rename check leaves on Android under
API 26 — or a plain file made the commit drop the verified staged tree and
return a generation that cannot be read back.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): never delete a cache because a manifest read failed

The adapter mapped every `file.text()` throw to null and the reader treated
null as corruption, so one iOS data-protection or I/O blip deleted the only
verified generation a host had. Missing stays null and still drops the tree;
a failed read now throws, and the reader returns no activation without
touching disk, leaving the caller to redownload.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the generation store's unreachable build-id guard

`MobileWebBundleManifestReadSchema` already pins `buildId` to the sha256
pattern, so no manifest reaching the store can fail the second check.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin that eviction ignores a non-host directory

Dropping the host-key filter in `listHostDirectories` passed the whole suite;
the ceiling would then count and evict anything else under the OS cache
directory.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a mid-download host out of the cache ceiling

A host holding only a staging tree was counted against the four-host limit
and, having no index entry, sorted first for eviction, so four cached hosts
plus one download meant the next activation deleted the tree that download
was about to commit. The ceiling now counts hosts with a generation; sweeping
still walks every host directory.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): record recency when a commit finds the build already active

The same-build early return skipped the index write, so a host that
redownloaded the bundle it already had stayed the least recently activated
and was the first evicted. No eviction pass on that path: the host count is
unchanged.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): honour only staged handles the store itself issued

`StagedGeneration` is structurally typed, so any object of that shape made
`commitGeneration` rename over, and `abortStagedGeneration` delete, a
directory of the caller's choosing. Handles are tracked in a per-store
`WeakSet` and anything else is refused before a filesystem call.

Jinwoo Hong 1e7a69710d feat(mobile): update wall for the desktop-served mobile web bundle (OTA phase B, 1/4) (#21411)
* feat(mobile): decide whether a web bundle may open against its host

A pure verdict for the bundle update wall, ordered so the answer names the
soonest cause: a host with no bundle has no manifest to disagree about, and an
unknown manifest schema makes the protocol window inside it unreadable. Same
`?? 0` defaults as `evaluateCompat`, so an absent status field reads as the
oldest host that could have answered rather than as permission.

Every blocked verdict is terminal. There is no native workspace fallback, so
each one carries the numbers it compared for the support breadcrumb.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): read an unknown bundle schemaVersion through to the wall

The client reader pinned `schemaVersion` to the one schema this shell knows, so
a future schema 2 failed the parse before `evaluateMobileWebBundleCompat` could
call the shell too old. The user would have seen a transport error where the
update wall belongs.

The host's own manifest stays closed in both directions, where it is written.
Goldens are unaffected: every recorded reply carries schema 1.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): give the block screen copy for the bundle walls

One component still renders every wall. `updateSide` picks the app to update
from the reason, so the copy and the store link cannot disagree, and a new
reason is a compile error there rather than a mobile title over a desktop
button. The existing protocol copy is unchanged.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): type the bundle protocol window the update wall compares

The loose reader left `runtimeProtocolVersion` and
`minCompatibleRuntimeProtocolVersion` as unknown index members, so the parsed
manifest could not reach `evaluateMobileWebBundleCompat` without a cast. Both
are now read as non-negative ints, and the reply-schema test pins it at the
call site: the wall is invoked on a parsed manifest, so dropping either field
stops compiling.

A host that omits the window is now refused. Only a host too old to advertise
`mobileWeb.bundle.v1` can send one, and the phone never asks such a host for a
manifest. The probe test's fake manifest gained the fields it was missing,
which is the typed reader catching its first stale fixture.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): say whether a bundle verdict actually checked a manifest

`ok` meant two different things: the manifest was read and its window contains
the host, or no manifest had been read at all. A caller that mounted on the
second would mount an unchecked bundle, so `manifestChecked` separates
permission to fetch from permission to open.

The host-status input is now a `Pick` of `HostStatusReply` instead of a
hand-copied pair. Both fields default through `?? 0`, so an upstream rename
would have silently blocked every host rather than failing a build.

Drops two assertions that restated the module's own literal back at it. What
proves today's bundle opens is that the shared contract's schema version is a
member of the supported list, so that is the assertion left standing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): offer a refetch, not a store, for a bundle the host outgrew

`bundle-incompatible` on the mobile side means the workspace cached for this
host is older than the host's client floor. A store update cannot clear that
and a reconnect can, so the screen no longer sends the user to a download that
would change nothing. The button is gone rather than relabelled, because the
recovery is leaving this screen, and the note drops its "already updated?"
opener for the same reason.

`blockRemedy` replaces `updateSide` and is now passed to the copy instead of
recomputed there, so the title, the body, and the button are decided once.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): drop the platform assertion from the block-screen mock

The mocked `Platform.OS` was widened with an assertion so a test could switch
stores. An annotation on the binding does the same widening in a position the
compiler checks, which is what the changed-code quality gate asks for.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say which bundle-compat default is fail-open, and drop a dead field

Both comments claimed the two host-status defaults point the same way. Only
`protocolVersion` is absent-means-oldest. An absent `minCompatibleMobileVersion`
is `?? 0`, which is no floor at all, so the mobile arm is fail-open by design
and matches `evaluateCompat`. A reader taking the old sentence at face value
would have gone looking for a bug.

`supportedSchemaVersions` had no consumer on the verdict: the block screen
renders a title and body, and B4 reads neither. The exported constant stays,
since that is what the wall is decided against.

Jinwoo Hong 60a774c30c feat(mobile): client operations and dev probe for the desktop-served mobile web bundle (OTA phase A, 5/5) (#21374)
* chore(rpc-contract): provisional catalog entries for the mobile web bundle methods

PROVISIONAL, and the only commit on this branch that must not survive the merge
as written. `rpc-params-catalog.generated.ts` is generated from the host method
registry, and A5's client operations cannot name `mobileWeb.bundle.manifest` or
`mobileWeb.bundle.chunk` until A3 registers them: `defineRpcOperation` constrains
`method` to `RpcMethodName`, which is `keyof typeof RPC_PARAMS_BY_METHOD`.

These two entries are what the generator emits once A3 lands. After merging A3,
run `pnpm run generate:rpc-params-catalog` and keep its output, not this.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): checked client operations for the desktop-served mobile web bundle

Two `defineRpcOperation` descriptors over the A1 contract, both
`require-result-or-throw` at `on-settle`: there is no partial success in a bundle
read, and a salvage policy would produce a half-bundle that fails a hash check far
from the cause.

Readers are hoisted `looseObject`s that require only what this client reads, so a
later optional member stays a Rule 1 addition for released phones; the host's own
schemas stay strict. `dataBase64` is bounded by the contract's chunk size, so a
host that overshoots is refused at the boundary rather than at reassembly.

`readMobileWebBundleErrorCode` maps the host's six codes out of the thrown
`code: message` diagnostic and answers null for everything else. Membership comes
from the contract's own enum, which is built from its `hostUnionArms` record, so
the arms here cannot drift from the host's union.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): fetch and verify a whole mobile web bundle over the paired connection

`fetchMobileWebBundle` reads the manifest, pages every asset at the chunk size the
host advertised, and verifies each reassembled asset against the manifest's sha256
before returning it. Nothing is cached and nothing is rendered: this is Phase A's
proof that the pipe carries a bundle intact.

Four asset reads run at once and no more, because the host refuses the fifth
concurrent read on one connection with `mobile_web_bundle_read_limited`; paging
inside an asset stays sequential, since the next offset is only known to be wanted
once a reply says it is not the last.

Every chunk reply restates its build, path and offset and the whole asset's length
and hash, and all five are checked. A desktop that auto-updates mid-download
answers a later chunk from a different build, and nothing else in the reply says so.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): dev-only troubleshooting row that fetches the mobile web bundle

The Phase A proof that the pipe works on a device. Tapping it fetches the whole
bundle from the paired desktop and reports the build, asset count, byte count and
elapsed time, or the host's error code.

`TroubleshootView` gains a `developerRow` slot and the route fills it only when
`__DEV__` is true, so a shipped build mounts nothing: no host lookup, no client
acquisition, no request. The row reuses the screen's existing button and check-row
styles, so it adds no visual vocabulary.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): recording scenarios for the mobile web bundle operations

Two families over the real product modules: `mobileWeb.bundle-manifest` drives the
manifest descriptor alone, so the loose reader's verdict on one reply is the whole
observation, and `mobileWeb.bundle-fetch` drives the paging flow over a two-asset
bundle whose entrypoint spans two chunks.

The fetch family's state carries the decoded bytes of every asset rather than a
count. A reassembly that misplaces a chunk still has the right length, so only the
bytes say so.

Goldens land with the repin in the next commit: the recorder fences on the pinned
tree, and these modules are not in it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the recording corpus and record the mobile web bundle goldens

`--record` refuses on any tree but the pinned one, and the pin predates this
branch's product modules, so the corpus is repinned to `bbf8264425` — the last
commit here to touch a fenced path — and re-recorded whole, the way
`rpc-recording/README.md` prescribes for a product change.

The delta is the clean one that repin predicts. All 778 existing goldens move
exactly one line, `baseline`, and nothing else: no body moved, no other header key
moved, none was deleted. Nine are added, two pilot per family plus the five reply
matrices the two families derive.

The fetch adapter projects its result rather than returning it whole. The result
carries a Map of Uint8Arrays, the observation refuses a non-plain object, and the
first recording lost the settlement and filed an unhandled rejection in its place.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): read the fake host's params through a boxed field read

The changed-code casting gate refuses the assertion the fake transport used to
type its recorded params. Boxing the value the way `settings-read-operations.ts`
does reads the same fields with no assertion, and a non-object params reads as
absent instead of throwing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus to this branch's last fenced commit

The casting fix landed under `mobile/src`, which is a fenced path, so the pin no
longer named the tree `--record` runs on. Repinned to `79c3eed6db` and re-recorded.

Every golden moves the `baseline` header and nothing else, which is what a repin
with no product change is: the edited file is a test, and no recording loads one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): mutation evidence that the fetch projection observes the bytes

Writes every chunk at offset 0, so a multi-chunk asset reassembles as its last
chunk over a zero-filled buffer. The length still matches the manifest, so only
the sha256 check and the decoded bytes in the projection can see it, which is
what the fetch family's state exists to show. The mutant is killed.

`mutants/` is outside every golden digest, so this moves no recording.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop every worker's chunk reads the moment one asset fails

`stopped` was read only between assets, so the other three workers paged their
asset to the end after the fetch had already rejected: 121 chunk requests where
4 had been issued at the rejection. Each one holds one of the host's four read
slots, so an immediate retry was refused with `mobile_web_bundle_read_limited`
that only the abandoned workers caused.

An internal AbortController now stands beside the caller's signal and is checked
before every chunk request, not just between assets. Also pins the entry abort
check, the overrun check with real bytes, the measured byte total, and a schema
refusal whose message is prose rather than one of the six codes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the code anchor and both operation descriptors

`RPC mobile_web_bundle_unavailable failed` separates the anchored reader from an
unanchored one; the prose test that claimed to cover it had its first token at
index 0, so the anchor was load-bearing and untested. Also pins that a schema
refusal, which the dispatcher raises with zod prose before the bundle handler
runs, reads as no code, and that both descriptors stay
`require-result-or-throw` / `on-settle`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): dial the host on tap in the dev bundle row, and name it

Opening Troubleshoot in a dev build acquired a client at mount, which is what
kicks a dial, on a screen that opened no connection before. The probe now
acquires only once the row is tapped, and each request owns its AbortController
so a re-run, an unmount or StrictMode's second mount abandons the previous fetch
and stops its chunk reads instead of holding the host's read slots.

The screen carries no host parameter and troubleshoots every paired host, so
there is no host it is "on": the row still takes the first paired host but now
names it in the result instead of implying it speaks for all of them. The label
says whether it is still connecting or already fetching.

There is no `__DEV__`-conditional `require` idiom in this repo to trim the row
out of a release bundle with, which the route now records.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): refresh the recorder corpus counts

397 scenarios, 787 goldens, 790 tests from the README's own three-file command.

* test(mobile): repin and re-record for the mid-asset stop

Baseline moves to c519c2027d, the last commit on this branch to touch a fenced
path, and the whole corpus is re-recorded from it.

Delta against the pin, by the README's four classes: 786 header-only, 1 body
moved, 0 added, 0 deleted. The only key that moved on the 786 is `baseline`;
neither `recorderSha256` nor any `adapterSha256` moved, so nothing this branch
touched is inside a hashed recorder path.

The one body move is the disclosed behaviour change.
`matrix-mobileweb.bundle-fetch-app-js.json` is the reply matrix at the app-js
binding: where a partition leaves the app-js chunk without a result, the fetch
now stops the other workers mid-asset, so the sender list loses the chunk calls
they used to make for a bundle nobody would read.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): hold the rendered tree and the captured signal in boxes

Assigning to a `let` inside a callback leaves it narrowed to `null`, which the
harness was answering with two type assertions. A one-property box is a checked
type and the casting gate no longer has anything to report.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus to the branch's final fenced commit

Removing the two type assertions touched a test file under `mobile/src`, which
is inside the fence, so the pin moves to cae8f4a318 and the corpus is recorded
again from it.

Header-only, as a repin with no behaviour change should be: 787 header-only, 0
body moved, 0 added, 0 deleted, and `baseline` is the only key that moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let runRpcOperation send a params-less method

A3 declares `mobileWeb.bundle.manifest` with `params: null`, so the generated
catalog types its send params as `void` and the two call sites that pass an
explicit `null` stopped compiling.

`bindDeferredRpcOperation.request` already solved this: `RpcSendArguments`
admits `null` exactly where the catalog declares no params, because
`params: null` is not the frame that omits the key and narrowing it would
rewrite bytes shipped senders already put on the wire. `runRpcOperation` was
the one send entry point that never adopted the tuple, having had no
params-less caller until now. The compile fence pins all three accepted
shapes and that a params-bearing object is still refused.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus after merging main

The merge brought A3's host methods and the generated catalog, and the
follow-up widened runRpcOperation, so `mobile/src` and `src/shared` both
moved. Repins `baseline` to 5be50beb41, the last commit to touch a fenced
path, and re-records everything.

Delta against that commit: 787 header-only, 0 body moved, 0 added, 0 deleted.
The only header key that moves is `baseline` — the transport change is
type-only, so nothing a screen observes changed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): bound the bundle a manifest can make the client allocate

M1: the loose client reader kept every ceiling A1 declared except the one
that bounds their product. A manifest could pass `totalBytes` 0 alongside
256 assets of 10 MiB each and the fetch would allocate 2560 MiB against a
32 MiB contract. The reader now sums `assets[].byteLength` against
MOBILE_WEB_BUNDLE_MAX_TOTAL_BYTES. A ceiling rather than the host's
sum === totalBytes equality, because this client never trusts `totalBytes`
for anything and bounds what it will actually allocate instead.

L1: a tap dials the host, and nothing bounded that wait. A host whose client
never arrives left the row reading `Connecting…` with its button disabled
for the life of the screen. A deadline through the diagnostics folder's own
`startDiagnosticFetchTimeout` settles it to a failure and drops the
acquisition. Ten seconds, because acquiring a client is local work: the
connect and request timeouts live below this and only apply once one exists.

L2, four survivors now pinned: the eof break against a zero-byte asset end to
end, the offset half of the chunk echo check on its own, the anchor that
keeps `rpc (mobile_web_bundle_unavailable)` from reading as a code, and both
`abandoned` guards against a run the screen moved on from.

Also: the stop check moves above the per-asset buffer, which makes the
worker loop's copy redundant; drops the unreferenced chunk reply type; and
restores the comment pairing in operation-mutations.ts, where the bundle
entry had been inserted between the catalog mutation's comment and its entry.

Repins `baseline` to 3252779fa7, the round-2 product commit, and re-records

and `baseline` is the only header key that moves. `recorderSha256` holds even
though `mutants/operation-mutations.ts` changed, because the mutant directory
is excluded from the recorder digest on purpose — nothing on the recording
path reads it.

A4 (#21376) added a mobile/src file inside the recorder fence, so the pin

Jinwoo Hong b90837ee46 feat(mobile-web-bundle): advertise the bundle capability where a bundle ships (OTA phase A, 4/5) (#21376)
* feat(mobile-web-bundle): advertise the bundle capability where one ships

status.get pushes mobileWeb.bundle.v1 only when the install's bundle resolves and
its manifest parses, beside the other conditional capabilities. Dev trees and
`orca serve` installs may carry no out/mobile-web, and a static entry there would
promise a download that only ever answers mobile_web_bundle_unavailable.

No protocol version bump: protocol-version.ts asks for one when a method or a
required field is removed or changes meaning, not when a capability is added.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin that mobileWeb.bundle.v1 is inert on a released client

Derives the old desktop's reply by removing the one capability from what the new
one sends, rather than writing down what the old client had, and asserts every
released read of status.get lands identically apart from that string: the gate
hook, the three transport readers, the quick-command predicate and the
worktree-create support probe.

Proved red against three mutants: a closed enum on the capability schema (the
salvaged field drops whole, so nothing publishes), a client-side filter over the
new name, and a gate that changes floatingWorkspaceEnabled when it sees it.

* chore(mobile): name the invariant behind the fake client's cast

The changed-code casting gate wants the rationale on the line, and the reason is
narrow enough to state: every reader under test reaches the client through an rpc
operation's `request`, which uses sendRequest alone.

Jinwoo Hong 1cd2964501 perf(mobile): build the two projected git enums once, not per parse (#21311)
`readProjectedConflictOperation` and `readProjectedCompareStatus` constructed
a `z.enum` on every call, so every `git.status` and `git.branchCompare` reply
paid the constructor. Hoisted to module constants; the git-status payload
schema reuses the same instance. Behaviour is unchanged: same arms, same
fallbacks, identical reader output on all eleven recorded matrix cases.

Jinwoo Hong 40b2230508 test(mobile): typecheck the test files on a ratchet, and pin the reply enums where tsc looks (#21298)
* fix(mobile): move the last six reply-enum pins where tsc looks

mobile/tsconfig.json excludes *.test.ts, so a `Record<HostUnion, true>`
coverage record in a schema test is never typechecked: the two that existed
(SshConnectionStatus, GitHubProjectOwnerType) checked nothing, and the four
closed enums beside them had only a doc citation of the host type.

Each arm list moves into its schema module as hostUnionArms<Union>(), which
#21269 introduced for the same reason, and each test iterates the exported
list instead of holding its own copy:

- SSH_CONNECTION_STATUS to SshConnectionStatus
- PROJECT_OWNER_TYPE to GitHubProjectOwnerType
- DETAIL_FILE_STATUS to GitHubPRFile['status']
- PUSH_TEST_REFUSAL_REASONS and PUSH_REGISTER_REFUSAL_REASONS to the refusal
  arms of MobilePushTestResult and MobilePushRegisterResult
- SETUP_RUN_POLICIES to SetupRunPolicy

openEnum's parameter widens from a non-empty tuple to `readonly string[]` so
a hostUnionArms list can feed it. z.enum already accepts the same, so the
tuple constraint only excluded callers zod itself takes; behaviour unchanged.

Twelve mutations prove the pins: dropping one arm and adding a bogus one
each fail mobile tsc in all six places. Zero goldens move, the schemas'
behaviour being unchanged, and the 21 recording suites pass at the existing
baseline.

* test(mobile): fix the type errors in eighteen test files

Found by typechecking the tests for the first time (see the config that
follows). All mechanical, none weakens a product type:

- 67 `act(() => vi.advanceTimersByTime(...))` callbacks return VitestUtils
  where act wants void, so each becomes a block. The async ones await only a
  genuinely promise-returning call, so no extra microtask tick is introduced.
- Four fixtures were stale against a product type that gained a required
  member: MobileViewState.alwaysShowDefaultBranch, PrSidebarData.checksError,
  the branch-compare summary's errorMessage, and SessionOptionDescriptor's
  transport, which #20884 added precisely so a producer could not inherit the
  wrong lane's rendering by omission.
- `getLastConnectedAt` on the shared relay fake was typed `() => null`, which
  refused the timestamp two escalation suites assign to it.
- Two holders used before assignment take `!`, one `advance!.kind === ...`
  becomes `advance?.kind`, one widened status arm takes `as const`, and the
  Expo notification fixture keeps `data` required because the dismissal cases
  assign through it.

631 test files pass, 6222 tests, unchanged.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): typecheck the test files, on a ratchet

mobile/tsconfig.json excludes *.test.ts so Metro never compiles tests into the
release bundle, and vitest transpiles without checking types. Nothing had ever
typechecked a mobile test, which is why a `Record<HostUnion, true>` pin written
in one proved nothing and why 144 of the 630 test files had drifted.

tsconfig.test.json is that program with the tests put back, behind
`typecheck:tests`. Four files stay out: they import the desktop main process or
src/shared/child-process, which are written against @types/node, and this
program's libs are React Native's, where setTimeout answers a number rather
than a NodeJS.Timeout. Pulling that graph in reports ~280 errors about the
desktop rather than about mobile; vitest runs those four under Node, which is
where they belong.

The CI gate is a ratchet rather than the raw typecheck, modelled on
check-ts-nocheck-ratchet.mjs: 126 files still fail, so the gate freezes that
set and fails when a file that checks today stops checking, or when a baseline
entry starts checking and was not pruned. The list may only shrink.

Why not zero: 180 of the remaining 510 errors are one seam — tests locate
mocked react-native components by string name, which `ElementType` does not
admit — and closing it means either 180 casts or a global JSX declaration for
the mocked names. That is a design decision, not a mechanical fix, so it is
left for a follow-up rather than made here. The rest are smaller clusters of
the same kind: vi.fn mocks assigned into typed slots, call-arg tuple indexing,
and createElement props fixtures.

* docs(mobile-recorder): correct the corpus counts and the salvage claim

The oracle section still quoted the corpus as 368 scenarios and 727 goldens;
it is 393 and 778, and the three replay suites report 781 tests. Each number
now names the command that measures it.

"No golden carries one" was the load-bearing error: 44 goldens carry a
recorded `reply-salvage` today, starting with the push-test unknown-reason
scenario #21176 added for exactly that purpose. The paragraph claimed the
observation pins an absence when on those families it pins a recorded drop.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the tests-typecheck ratchet's parser

The gate reads tsc's output, and tsc indents the "Overload 1 of 2, ..." detail
under an error. Counting those as filenames would write unparseable entries
into the baseline and leave the gate unprunable, so the parser is pinned on
that shape as well as on the added/stale diff.

Written against the gate itself: it flagged this file before the directive it
carried was removed, which is the end-to-end proof the spawn half works.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): await the timer advances the act() rewrite dropped

Rewriting `await act(async () => vi.advanceTimersByTimeAsync(n))` into a
braced body left the returned promise floating at 27 sites, so the advance
was no longer ordered before the assertions that follow it.

* test(mobile): unshadow MobileHostCard's .tsx suite

A wildcard `include` keeps only the higher-priority extension, so
MobileHostCard.test.tsx sat outside every tsc program while
MobileHostCard.test.ts existed beside it. Its one error is the same
react-test-renderer seam its sibling is baselined for.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): census every test file into the typecheck program

The ratchet diffs only files that error, so a test excluded from
tsconfig.test.json or shadowed by a sibling extension left the gate
silently. Every *.test.ts(x) on disk must now be in the program or
named in TESTS_OUTSIDE_PROGRAM with its reason.

* fix(shared): make the enum helpers refuse the ways they can prove nothing

openEnum takes a `const` T so a bare literal keeps its arms rather than
widening to string. hostUnionArms blocks inference of U with NoInfer and

record would only pin itself — no longer compiles.

* test(mobile): build the push fixtures as typed notifications

Replaces the `as unknown as` cast with Expo's own types, filling
FirebaseRemoteMessage and its notification once in two builders, and
passes the data payload in rather than mutating through an optional
member. Typing the fixture showed one assertion comparing the scheduled
content against the whole arriving content, which only held while the
cast let the fixture omit the two members the presenter drops; it now
names the four members the presenter forwards.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

`advance?.kind` let an absent advance take the null-draft branch instead
of failing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): run the tests-typecheck ratchet on Windows

Spawns tsc's JS entry on this Node instead of the node_modules/.bin
shim, which is a POSIX shell script that Windows resolves to tsc.CMD and
then appends .exe to. Parsed paths are normalised to POSIX so a Windows
run does not read every baseline entry as both stale and added.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): close the ratchet's @ts-nocheck hole and read tsc once

tsc exits 0 on a @ts-nocheck file, so a baselined test could be "fixed"
with one line, pruned, and never checked again; the census now names any
program test file whose leading comment carries the directive.

`--noEmit --listFiles` answers both questions in one pass, so the gate
spawns tsc once rather than twice. Corrects the two stale counts, and
states hostUnionArms' real reason for living in the schema module now
that tests are typechecked.

Jinwoo Hong 49274394fc refactor(mobile): put the branch-compare leg on the lifecycle owner, with a currency probe (step 5) (#21299)
* refactor(mobile): put the branch-compare leg on the lifecycle owner (step 5)

The compare kept three hand-rolled guards for one reply, combined in an
`isCurrentLoad()` the four exit points each had to remember to call:
`branchCompareGenerationRef` (latest-wins), `currentBranchCompareIdentityRef`
(the route identity, written in render) and `mountedRef`.

The owner replaces the first two. An attempt now `reset()`s and then `load`s, so
the newest attempt is the only one holding a live lease, and the reply is
published only through `commit(lease, value)`. What retires a compare is named
at the call site: this host, this route identity, this workspace.

A compare is a refresh, so neither of the owner's other two mechanisms applies
here and the `reset()` before each `load` is what says so: nothing it holds is
reusable, and no attempt may share its predecessor's reply. Dropping that line
makes the second attempt join the first's request and publish a base ref the
user already navigated away from.

The identity retire moves into the render-phase adjust-on-prop-change block,
where the identity ref was written. Leaving it to the next load's scope is not
the same thing: that load only starts once the fresh `git.status` returns, and
an in-flight compare would publish the old worktree's commits first.

`mountedRef` stays. A detached route has no screen to publish to, which is a
fact about the view, not about which reply is current.

The three decision points that used to write state mid-flight — no base ref, a
refused capability, an unreadable reply — are a returned `BranchCompareOutcome`
now, so the loader body writes nothing and the screen is written in one place.
That also puts this file under the loader-write source fence.

No golden moves: the recording suites reproduce byte for byte.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): correct the compare scope comment to the one call that reads it

The pilot's wording named two scope consumers; the compare leg has only `load`.
What the scope still adds over the render-phase retire is the structural half: a
scope the owner has not seen retires on its own.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* feat(mobile): give the lifecycle owner's loader a currency probe

A loader that spans two round trips had no way to ask whether its scope
had moved, so a superseded attempt sent its second request and was only
refused at commit. The probe answers exactly the question commit asks and
carries nothing to publish with, so the owner's publish fence is unchanged:
a loader that stops on it returns null, which the owner already reads as
no value.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a superseded branch compare off the wire

Restores request-count parity with main for the one path the migration
changed: an attempt superseded while it resolved its base ref used to stop
before sending git.branchCompare, and under the owner it sent one and was
refused at commit. It now stops on the owner's currency probe between the
two legs, so the screen is unchanged and so is the request count.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say what the probe's missing generation actually is

Stripping the directive gives TS2339, a member that does not exist, not a
privacy error: the probe has no generation to keep private.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin that a detached route sends no compare

The detach reset() was the only thing retiring an attempt after the route
went away, and deleting it left the suite green. This schedule detaches
mid base-ref lookup and asserts nothing reaches git.branchCompare; without
the reset() it fails with one request sent.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the scope member the identity key already carries

statusIdentityKey is `${hostId}\0${worktreeId}`, so listing worktreeId
beside it read as a third fence when it fences nothing new.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): split the compare protocol out of the loaders hook

The outcome union, the attempt and the screen mapping are the compare
leg's own protocol, not the hook's: nothing in them reaches React. Moved
verbatim to mobile-branch-compare-outcome.ts with a unit pin for the
mapping, which only the hook's schedules covered before. The hook drops
from 283 to 230 lines against a 300 limit.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): correct the joiner comment and narrow the compare sender

A joiner never receives the probe: its fn is never invoked, it awaits the
originating request's promise, and retire() clears inFlight so none can
join across a generation bump. The compare attempt takes the operation
sender the convention names rather than a whole RpcClient, which it only
ever used as that.

Jinwoo Hong eabfbaab88 refactor(mobile): drop the unreachable dispose-before-ready notifications arm (#21293)
* test(mobile): pin the desktop-notification dispose-before-ready contract

Drives `subscribeToDesktopNotifications` through the real `RpcClientStreamRegistry`
so the disposer's effect on a later `ready` reply is stated rather than implied.
Both cases pass against the current module, before any code is removed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the unreachable dispose-before-ready notifications arm

`disposed` is set only on the first line of the disposer, whose next statement
detaches the stream listener in every transport, so the `ready` arm can never
observe it. Removing the branch changes no behaviour and moves no golden.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin cancel fencing in the relay and logical stream layers

The notifications comment claims every transport detaches a listener inside its
disposer, but only the stream registry was pinned. Adds the same live/cancelled
differential pair to the relay stream manager and the logical client, the latter
against a physical session with an inert disposer so only the logical guard can
fence the late event. Drops a self-comparing assertion to a length check.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): type the notifications registry fake instead of asserting it

The changed-code quality gate rejected three `as` casts. The fake client is now
declared `RpcClient`, so the compiler checks it really satisfies the port, and
the registry's `unknown` send port is narrowed by a reader that throws on a
frame without a string id and method rather than asserting one.

Jinwoo Hong 4a86b2dc56 refactor(mobile): checked reply readers for files, dictation, host-screen and agent-history (step 7) (#21269)
* test(mobile): record main's file-preview and markdown-disk-fallback replies

Four of this branch's read sites had no malformed-reply coverage, so the reader
change would have had nothing to move at them. `familyGoldens` matrixes only the
first scenario of each family, and `files.preview-load`'s base is the grant-refresh
chain while `session.tab-documents`' is the served markdown tab — which left
`files.read` and `files.readPreview` on the worktree preview path, the artifact
image read, and the markdown tab's on-disk fallback recorded on their success path
only. This commit is the before picture, taken from main's own tree with no product
edit in it.

Three new families, five scenarios, ten goldens:

- `files.preview-worktree-text` / `files.preview-worktree-image` — `files.read` and
  `files.readPreview` as the preview screen asks them for a worktree file.
- `files.preview-artifact-image` — `files.readTerminalArtifactPreview`.
- `session.markdown-disk-fallback` — the `files.read` leg a headless host's
  `renderer_unavailable` sends the markdown tab down. It carries a second scenario
  that serves `markdown.readTab`, because a matrix site needs a fulfilled reply
  recorded somewhere in its own family to replay as the `normal` partition.

No existing scenario moved to a new family and no adapter changed, so every
pre-existing golden keeps its `adapterSha256` and `scenarioSha256`. Recorded in a
detached worktree at the manifest's pin (`4b876758d3`) with this manifest copied in;
the control is that all 748 pre-existing goldens came back byte-identical to
origin/main's, which `git diff c2962a765a -- mobile/rpc-foundation/goldens` confirms
as empty.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): checked reply readers for files, dictation, host-screen and agent-history

Thirty-five unchecked reply readers across seven files become checked zod readers,
so a malformed host reply surfaces as one readable error at the operation boundary
instead of a downstream TypeError, a rendered `undefined`, or a screen left ready
over garbage. Deliberately a behaviour change on malformed replies only: every good
reply decodes to the same value it did, which the `normal` partition of every
matrix golden holds byte for byte. Nothing on the wire moves — no method, params,
options, timeout or acceptance policy changes at any site.

The inventory drops from 137 readers over 31 files to 102 over 24.

What each domain checks, and what it deliberately does not:

- files/preview — one schema for `files.read` and `files.readTerminalArtifact`, one
  for the two preview methods. `content` is required on the text pair because the
  markdown disk fallback publishes it into the tab with no guard; the image pair
  requires nothing, because normalizeImagePreviewResult guards all four members and
  the host's own "binary I cannot preview" and "not actually an image" arms are good
  replies the screen renders today.
- files/tab-doc — stricter than the preview screen on the same two methods, because
  a tab publishes what it read into a typed ready document with no guard. `git.diff`
  reads as two variants, and an arm this build has not heard of takes the binary one
  rather than refusing the reply.
- files/explorer — the directory listing is an array and a row needs the name and the
  directory flag the tree projection turns on; the legacy capped list needs its rows'
  paths and the truncation flag its note draws.
- files/ownership — the two members that decide *where a write lands* are fatal on a
  wrong type rather than salvaged, because absence reads as `local` downstream and a
  salvage would send a mutation to the wrong host. `hostId`'s absent/null/string
  states stay distinct, and the SSH connection generation passes through at its own
  type because the mutation echoes it back to the host.
- dictation — the setup the sheet renders is checked; the model rows need the `id`
  the sheet keys and sends back. The five sends whose reply body no call site reads
  keep an unknown payload, and so does `speech.dictation.finish`, whose transcript is
  read past a staleness guard that a reader throw would move the failure across.
- host-screen — the repo catalog, the SSH labels and the host platform. The four
  writes read no reply body; `worktree.activate` stays opaque because the session
  route's second report site awaits it outside any catch.
- agent-history — the capability gate and both scan containers. The session rows stay
  unknown on purpose: `agent` is a vocabulary that grows with every agent CLI Orca
  learns to scan and that this client echoes back on resume, so narrowing it would
  refuse a newer host's reply or drop the very sessions it added.

Two shared readers were widened to take the strings the reply readers hand them —
`getRepoExecutionHostId` and `buildRepoHostIdByRepoId` — because both already answer
`local` for a host-id spelling they cannot parse, and closing that spelling in a
reply schema would refuse a newer host's own catalog.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus and re-record the checked reply readers

`baseline` moves to this branch's last fenced commit, which is what `--record`
refuses without: main's fenced tree drifted past the session domain's pin when
#21114 and the dependency bump landed, and the product edit in the commit before
this one moves it again.

Every body move is confined to a malformed partition of a family this branch
touched. No `normal` partition moved, which is the byte-for-byte control on good
replies, and no golden outside the seven files' families moved at all.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): stop the dictation reader requiring a mode main rendered without

The setup sheet's `normal` partition refused after the reader landed, which is the
success control saying the schema was wrong rather than the fixture: `dictationMode`
was declared required because the one unguarded consumer pushes it into a
`useState<'toggle' | 'hold'>` and cannot invent a value, but main rendered a sheet
whose reply omitted it, and requiring a member no consumer crashes on is exactly the
version claim Rule 1 of the remote-wire contract warns about.

The member is salvaged now and keeps its open arm set, so an unknown mode still
degrades to `toggle` rather than to one that matches no segment. The native-chat
refresh spells that same `toggle` for an absent mode, which is the value its state
already started at, and the route parity pins are refreshed for the one literal and
the two callback bodies that moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin past the dictation fix and re-record

Second repin of the branch: the fix to the setup reader is a fenced-tree change, so
`--record` refuses until `baseline` names it. The speech family's `normal` partition
is back to main's projection, which is what said the first reader was wrong.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): mutant evidence for the checked reply readers

Three mutations applied by hand, run, and reverted, recorded beside the adapter
family mutations in the same shape. They are kept in their own file because a reader
mutation is not killed by a pilot scenario: a pilot serves a good reply, and a schema
that has stopped checking a member reads a good reply exactly as before. What kills
them is a matrix golden's malformed partition, the schema's unit pin, or a consumer
pin, and each is named against its mutation.

Two survived their first run, and both survivals were defects in the gates:

- Loosening the file tab's `content` was invisible, because the pin dropped members
  only in pairs and each pair is refused by the sibling. The pin now drops exactly
  one member per iteration, and the preview text schema and the legacy file list got
  the same treatment.
- Collapsing the hostId tri-state was invisible, because no golden serves an explicit
  null host — the local ownership scenario omits the member. The ownership test now
  captures all three states end to end, which is where a tri-state belongs.

`repo-metadata-platform` is re-anchored where this branch moved the read it mutates:
the hand-rolled `readHostPlatform` became the reply schema's own projection. The
defect it injects is unchanged.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record main's repo-icon and speech-vocabulary replies

The closed enums this branch introduced had no fixture behind them. `provider`,
`dictationMode` and `repoIcon` were carried by no scenario at all — the fulfilled
repo-metadata golden records `repoIconsByName: []` — so the corpus could not have
moved whatever arm set the schemas declared, which is how a reader can pin a
vocabulary the host does not speak and still decode to a zero-move delta.

Two scenarios, both appended to an existing family so `familyGoldens` adds no
matrix golden, recorded from main's own tree at the pin with no product edit in it:

- `settings-repo-metadata-icons` — all three `RepoIcon` arms, a github-sourced
  image with a label, an explicit `badgeColor`, and a mixed-host catalog so the
  ssh/settings/platform wave runs too.
- `speech-setup-sheet-model-vocabulary` — `provider` on both arms, `status` on two,
  `dictationMode: "hold"`, and null and numeric `sizeBytes`/`progress`.

Control: re-recording the whole corpus at the pin reproduces every committed

* fix(mobile): stop the repo icon narrowing a member no consumer reads

The image arm of `repoIcon` declared `source` as the four values
`RepoIconImageSource` spells today (src/shared/repo-icon.ts:3). MobileRepoIcon
reads `type`, `src`, `label`, `emoji` and `name`, and never `source`, so the only
thing that enum could do was fail the union arm for a source a later host adds —
dropping the whole icon and drawing the Folder default where main drew the image.
That is the one arm set on this branch whose degrade was not already main's own
behaviour for an unknown value.

Dropping the declaration keeps the member: `looseObject` passes it through
verbatim, so the decoded object is byte-identical to the one main published, which
`settings-repo-metadata-icons` now records.

The two type sites that hold an icon move to the decoded type. A host `RepoIcon`
still satisfies the rendered union, so the worktree rows that carry one are
unaffected.

Every other closed enum on this branch was checked against the host's own shared
type and left alone: speech `provider`/`status`/`dictationMode`
(runtime-worktree-contracts.ts:83/85/86), `groupBy`/`sortBy`
(persisted-ui-state-types.ts:41-42), `platform` (Node's own domain; the handler
answers `process.platform`). For each, a salvaged member lands on the same branch
main's unknown value did: `=== 'openai'` and `=== 'ready'` stay false, a missing
`groupBy` and an unmapped one both answer null, and an unknown platform and a null
one both label the host "This computer".

* test(mobile): repin past the repo-icon fix and re-record

Header-only: all 770 goldens move on `baseline` alone, including the two recorded

the bytes main published.

* fix(mobile): keep the repo-metadata readers total the way main's were

readSshTargets and readHostPlatform answered [] and null for any payload at
all. The checked schemas threw for a non-object, and because the label write
runs first in the same sequence that throw also skipped the platform write, so
a malformed reply left both decorative labels at their previous values instead
of degrading. A .catch on each restores main's answer without giving up the
row filter or the checked reader.

* fix(mobile): forward the dictation mode instead of substituting a default

The reader closed the mode to two arms and the native-chat refresh spelled
`?? 'toggle'`, which is a good-reply change no golden covers: main left the
state undefined for a reply that omits the mode, and undefined binds no press
handler on the terminal input mic. Head gave that mic a working toggle. The
member is forwarded as the string the host sent and the refresh is main's line
again, so an absent or unknown mode leaves the mic exactly as inert as main's.
The route-parity runtime-string pin is main's own sha again.

* test(mobile): repin past the review fixes and re-record

The repo-metadata readers are total again, so both families' `result-absent`

verbatim, which no recorded reply exercises differently.

Resolved every citation in the seven reply-schema modules and the SAFETY
notes against the tree and diffed each target line against the claim beside

so they read as evidence while pointing at a closing brace.

- file-explorer: the entries put is :157 not :160, the relativePath split is
  file-list-fallback.ts:48 not :42, and the truncated publish is :136 not
  :141. buildFileExplorerRows is no symbol at all; the sort-and-walk is
  flattenDirectoryCache (file-tree.ts:58).
- file-ownership: the !summary throw is :68 not :64.
- file-preview: the markdown disk fallback reads content at :60 not :65.
- file-tab-doc: the html body render is :68 not :81 and the file arm is
  :73-75 not :86-88 (the file has 78 lines); the isImage guard is :58 not
  :66; the kind !== 'text' branch is :41 not :44; mobileDiffImageDataUri
  spans :22-33 not :20-31; the unguarded content.length is
  mobile-diff-lines.ts:35, the function that does it rather than :34.
- agent-history: both members land at :133-135; :135 alone is issues.
- dictation: the parenthetical read as citing the staleness guard when it
  named the rpcPayloadMember read. Both are cited now, :237 and :225.

* docs(mobile): name the unguarded activation report site that pins the opaque schema

Handler audit over all 33 interpret sites in the four domains found one site
that is structurally unguarded: use-mobile-session-startup.ts:170 reports the
activation verdict from inside a fire-and-forget `void (async …)()` whose only
`.catch` sits on the request, not on the chain. A throw there would be an
unhandled rejection and would also skip the terminal fetch below it.

Nothing throws there today, because `worktree.activate` reads
hostScreenUnreadReplySchema, which is `z.unknown()`. That totality is load
bearing rather than incidental, so the doc now names the line it protects and
contrasts it with the first report site at :141, which is chained
`.then(…).catch(…)` and would survive a throw.

* fix(mobile): pin the closed reply enums to the host unions where tsc looks

pullfrog: the PR body promised a Record<HostUnion, true> pin for every
closed enum in this batch and the code had none. Adding them in the
schema tests would have changed nothing: mobile/tsconfig.json excludes
*.test.ts, so a coverage record there is never typechecked (a mutation
that dropped a key stayed green).

hostUnionArms(coverage) in zod-salvage spells the arm list as a
Readonly<Record<U, true>> in the schema module itself, called with the
host union as the explicit type argument: an arm the host adds is a
missing property, one it drops is an excess property. Used for the speech
provider and status (RuntimeSpeechModelSummary), the workspace groupBy and
sortBy (PersistedUIState) and Node's platform list, which host-screen now
imports from mobile-runtime-host-platform instead of duplicating. The repo
icon branches satisfy Readonly<Record<RepoIcon['type'], z.ZodType>>.
Three mutations (drop `manual`, add `bogus`, drop the image branch) each
fail tsc. The tests iterate the exported lists; the platform mutant is
re-anchored to the renamed constant.

Jinwoo Hong 6142657d7a refactor(mobile): checked reply readers for the tasks domain's board, runtime, search and create (step 7) (#21246)
* test(mobile): record main's agent.launch create receipt before checking it

`agent.launch` is the one read site in the tasks domain's project-board,
runtime, source-search and workspace create/source files with no recording
family at all, so main's answer to a malformed launch receipt was undocumented
and a checked reader would have had nothing to move.

One family, one scenario, two goldens: `worktree.agent-launch-create` drives
`createWorktreeWithNameRetry` down the `agent.launch` arm instead of
`worktree.create`, which needs an `agentLaunch` argument on the existing
worktree-create-retry adapter. The agent is a constant there on purpose — which
agent is picked changes only the params, and the arm under test is which method
the create is issued on.

A separate family rather than an eighth `worktree.create-retry` scenario:
`familyGoldens` drives its reply matrix over the family's FIRST scenario, so
adding to that family would have recorded a pilot golden and left the launch
receipt with no partitions. As its own base it gets all eleven.

Recorded from a detached worktree at the pinned baseline with this branch's
`rpc-recording/` and manifest copied in, per the recipe in the recorder README:
`mobile/pnpm-lock.yaml` has drifted past `4b876758d3` on main, so `--record`
refuses on this branch's tree even though `mobile/src` and `src/shared` are
byte-identical to the pin.

Thirty-four existing goldens move on `adapterSha256` and nothing else — the six
families mounted through the edited adapter module. No body moves.

* refactor(mobile): checked reply readers for the tasks domain's board, runtime, search and create

Forty-three unchecked reply readers across five files become checked zod readers,
so a malformed host reply surfaces as one readable error naming the method
instead of a downstream TypeError, a rendered `undefined`, or a screen left ready
over garbage. Deliberately a behaviour change on malformed replies only.

Five schema modules, each recording the consumer line behind every requirement
and the host handler it was checked against:

- `task-project-board-reply-schema.ts` — the sixteen `github.project.*`
  envelopes. Where a consumer reads a member off BOTH arms unguarded the schema
  is a union on `ok`; where it guards everything (`result.error?.message ?? '…'`,
  `result.labels ?? []`) it is a flat passthrough and requires only the
  container, because a requirement on a member the consumer already defaults
  would refuse a reply main rendered.
- `task-runtime-reply-schema.ts` — the hydration reads. The three preference
  writes read `z.unknown()`: no call site interprets their body.
- `task-source-search-reply-schema.ts` — the provider searches and the pasted
  single-item lookups. The Linear union replaces the hand reader in
  linear-mobile-issue-read.ts, whose own copy reached the screen unattributed.
- `workspace-source-reply-schema.ts` — SSH state, agent detection, orca.yaml
  hooks, sparse presets and base-ref search.
- `workspace-create-reply-schema.ts` — the create receipt, the launch receipt and
  the hosted-base union.

Requirements are exactly the members a consumer reads unguarded AND a recorded
golden shows the host sending. That second half is load-bearing: the recorded
GitHub search row is `{ number, title }`, the recorded Linear issue is `{ id }`,
the recorded project is missing `id`/`url`/`source` and the recorded sparse
preset is missing `repoId`/`createdAt`/`updatedAt` — requiring what the shared
types declare would have dropped rows main renders. Where the value therefore
stays looser than the screen's own state type, the call site keeps one narrowing
cast with that reason on it rather than a default that would fabricate state.

Two enum decisions, both pinned:

- `ownerType` is CLOSED with no fallback. It is echoed into the next
  `github.project.listViews` params, and remote-wire-compatibility.md rule 4
  forbids a reply-schema fallback from shaping a param; the host's own listing
  handler answers `validation_error` for any other value.
- `ssh` `status` is OPEN and degrades to `disconnected`, main's own answer for a
  state it did not receive. The readiness gate is an equality test against
  `connected`, so an arm this build has not heard of can never grant a create,
  and the record survives with its Connect affordance.
- Every other host vocabulary a consumer equality-tests — the project view
  `layout`, the `setupRunPolicy` — stays `z.string()` for the same rule.

Tri-states are preserved, not collapsed: the row detail's `reviewDecision`, a
work item's `author` and the SSH record's `error` each keep explicit `null`
distinct from absent, with a unit pin on each.

`blank-workspace-create.test.ts` splits one `it.each` in two. The two create
routes now answer a workspace-less reply differently: `agent.launch` still
reports "Failed to create workspace", because its reader guards `worktreeId`
itself, while `worktree.create` is named as unreadable, because the create screen
reads `result.worktree.id` unguarded into the session route. Both reach the same
catch; only the sentence changes.

`mobile-tasks-refactor-parity.test.ts` moves four hashes and no count. Hooks hold
at 350 with 28 bodies edited and no dependency array moved; statements hold at
417 and declarations at 194; `semantics` loses exactly four lines, all four
string literals that lived inside the one deleted inline cast type. No method
literal and no `rpc:` call signature moves.

The inventory loses its five tasks lines; the boundary test stays green.

Goldens are refreshed in the next commit, which is where the disclosed behaviour
change is proved.

* test(mobile): repin and re-record the corpus over the tasks domain's checked readers

Repins `baseline` to d4cfac98b4, the commit that landed the checked readers, and
re-records all 760 goldens. The repin rewrites that header on every file; the
recorder edit below rewrites `recorderSha256` on every file too.

The disclosed behaviour change is the body-moved set and nothing else: the
malformed reply partitions of the families whose readers this branch converted.

Two recorder files move with it, both re-anchoring evidence the checked readers
displaced rather than deleted:

- `pilot-recordings.test.ts` restates the b2 seed. The shipped null result is
  still the seed and the screen still reports an error the user can see; what
  moved is the sentence, from V8's "Cannot read properties of null (reading
  'ok')" to the reply and method the reader names.
- `operation-mutations.ts` re-anchors that seed's `acceptance` mutant. Its defect
  is a null envelope reaching the metadata sheet, and the call-site guard it was
  injected at can no longer see one, because the reader refuses the envelope
  first. The anchor is the schema now, and loosening it to `z.unknown()` puts the
  null back on the path to `result.ok` — the same defect at its new home.

* test(mobile): assert the reply-schema pins without type assertions

The changed-code casting gate counts a `as` in a test like any other, and eight
of them had crept into the new schema pins. Each is replaced by an assertion that
reads the same fact off the typed value: the schema already declares
`worktreeCreateIdempotency`, `glab`, `status` and `error`, so the narrowing was
never needed, and the two "is this key present" checks are JSON comparisons,
which is the honest way to ask — `JSON.stringify` drops an absent key and keeps
an explicit null, which is the whole distinction a tri-state pin is making.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus to the tree it was recorded from

The previous repin named d4cfac98b4, and the assertion cleanup that followed it
touched `mobile/src` — a fenced path — so the header pointed at a tree the
working copy no longer was. Repins to 6b740c3f61 and re-records.

Bodies are unchanged: only `baseline` moves, on all 760 goldens. Four test files
cannot reach a recording, which is the point — the fence does not know that, and
a header that names a tree nobody can reproduce is the one claim it exists to
make.

* docs(mobile): point the reply schemas' consumer citations at the landed lines

Every requirement in the five schema modules names the consumer line that
justifies it, and the migration moved those lines: deleting a thirty-line inline
cast type shifts everything under it. The citations now resolve against the tree
they ship in.

Comment-only. No schema, no reader and no consumer changes.

`baseline` follows the last commit to touch a fenced path, and the citation fix
did. Bodies unchanged: `baseline` moves on all 760 goldens and nothing else.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin both reader vocabularies against the host's own unions

The two enums these readers declare were checked against mobile's restatement
of the wire, not against the types the handlers return. A closed enum written
from the wrong vocabulary drops every row that carries an arm it omits, and no
golden can catch it when no fixture carries one.

Both arm sets are now keyed by the host type in a Record, so an arm added to or
removed from SshConnectionStatus or GitHubProjectOwnerType fails tsc before any
test runs. The SSH degrade's inertness is pinned at the gate that reads it
rather than argued in a comment: an arm a newer host sends and the degraded
value reach the same label, the same readiness verdict and the same error.

Also corrects a comment claiming the file-mutation owner check reads members
this schema forwards. It asks ssh.getState through a reader of its own, and no
mobile code reads providerEpoch, supportsFolderDownload or remotePlatform.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus to the tree the vocabulary pins landed in

Comments and tests cannot change a decoded value, so the whole delta is the
baseline header key: 760 goldens, one line each, no body moves and no scenario
or adapter change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record real provider rows in the smart-search and paste fixtures

The smart-search and paste-lookup scenarios carried hand-written stubs, not
rows any handler can build: Linear issues of `{ id }` alone, GitHub items of
`{ number, title }`, and a GitLab item keyed by `iid`, a member neither work-item
type declares. Every one of them omits members the host's own types declare
non-optional and mobile then reads with no guard, so the corpus was evidence for
a requirement it could never have justified.

The rows are now the shapes the corpus already uses elsewhere (`tk-list-linear`,
`tk-provider-load`, `tk-list-gitlab-items`), checked member for member against
LinearIssue (src/shared/linear/issue-types.ts:3), GitHubWorkItem
(src/shared/github/work-item-types.ts:17) and GitLabWorkItem
(src/shared/gitlab-types.ts:165).

No schema moves in this commit. It records what main renders for a real row, so
the requirement that follows can be read against main's own behaviour rather
than against a stub.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): require the members the tasks readers' consumers read unguarded

Round-1 review found four unguarded consumer reads at members the corpus proves
the host sends, plus two the corrected fixtures now prove. Each one ends in a
TypeError inside a render or a useMemo, which is the defect class this migration
exists to close.

Required, each because a consumer reads it with no guard and the host's own type
declares it non-optional:

  title on an accessible project  project.title.toLowerCase()
  name, directories on a preset   localeCompare, and two joins
  labels on a work-item row       item.source.labels.filter, both label editors
  state.name, team.name, priority createLinearTask, and the reviewer sort

All six sit inside a salvagingArray, so a row that lacks one drops and the list
survives. The single-row paste lookup names the reply instead, because there is
no list for it to survive in.

Loosened in the other direction: the SSH record no longer requires `error` or
`reconnectAttempt`. Nothing reads either one — the gate spells
`matchingState?.error ?? null` and nothing anywhere reads reconnectAttempt — and
the record is a salvagedOptional, so requiring an unread member drops the WHOLE
record, whose fallback on the connect path is `fallbackSshState(id,'connected')`.
A reply of `{ targetId, status: 'auth-failed', error }` would have shown the
drawer as connected. Mobile's own stored type is widened to match; the shared
wire type is untouched.

The `iid` extension on the lookup row goes with it. Neither work-item type
declares such a member and every GitLab consumer builds its iid param out of
`item.source.number`.

* test(mobile): repin the screen parity hashes over the merged tree

Main landed the sibling tasks lane, which edits the same screen hook files this
branch does, so the merged tree hashes to neither side's constant. Both inputs
are legitimate: main's reply-schema conversions and this branch's WorkspaceSshRecord
rename.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): justify the smart-source casts by the schema, not the fixture

Five SAFETY notes argued from the corpus back to the wire: they justified a
cast by the stub rows the fixtures used to carry (`{ iid, title }`,
`{ number: 12, title: 'twelve' }`). Those rows were the defect corrected in
6763ff12e9, so the claims are now false, and the reasoning was never sound —
a fixture cannot say what the host may send. Each note now cites the schema's
own requirement rule, the host type and the consumer read.

Comment-only; no golden moves. The hook and statement parity hashes move
because `normalized` hashes a statement's full span, comments included.

* docs(mobile): repair the line citations this lane's own edits aged

Eleven citations across five reply-schema modules pointed at the wrong line.
Every one was correct when written and rotted afterwards: the SAFETY-note
rewrites, the F4 dedupe's deleted casts and the sibling lane's merge each
shifted the files being cited. A citation is the whole argument for a
requirement, so a stale one reads as a fabricated one.

Found by resolving every `file.ts:line` in the five modules against the merged
tree and comparing the line's text to the claim beside it, not by reading them.
The ones that still resolve correctly are left alone, including three that
looked stale and were not.

* fix(mobile): keep the two advisory task probes total so a nullish payload cannot unhydrate the screen

`preflight.check` and `linear.status` are read under `success-result-or-skip` and documented as
advisory. That policy accepts an envelope whose `result` is absent or null, then asks the reader to
decode it; a `looseObject` refuses, the throw leaves the reader, and the caller's catch discards the
entire hydration. The corpus records the difference: on the `result-absent` and `result-null`
partitions main hydrates the Tasks screen and lists one provider, and the checked readers left it
unhydrated with no providers.

`.catch` restores main's answer exactly. Every consumer guards to the leaf and compares to `true`,
so absence, null and a garbage payload have always meant "not installed" and "not connected".

Four cases pin it, and removing either catch fails all four.

* refactor(mobile): drop the Linear row cast the checked schema made unnecessary

`found` is already assignable to the mobile `LinearMobileIssue` alias once
`linearIssueRowSchema` requires its nine members, so the assertion and its
disable line carried no type error. The sibling cast in
smart-source-search-requests.ts stays: it targets the shared `LinearIssue`,
whose `labelIds` is required where the schema leaves it optional.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): rewrite the SAFETY lines that argued from deleted fixtures

Three casts still justified themselves with the `{ id }` and
`{ number, title }` rows this branch replaced in round 1, which reads as a
licence to loosen the requirements that close the reproduced crashes. Each
now names what its schema requires and what the cast actually covers, each
verified by deleting the cast and reading the error:

- Linear rows: all nine read members are required, so `labelIds` alone is
  the gap between the schema and the shared LinearIssue.
- GitHub search: `items` and eight row members are required; the salvaged
  `T | undefined` types and the deliberately opaque `sources`/`errors` are
  what remain.
- Sparse presets: `id`, `name` and `directories` are required; the cast
  covers the three SparsePreset declares that the reply omits.

* docs(mobile): resolve the bare :NN citations the first audit could not see

The earlier repair resolved only qualified `file.ts:line` citations, and
these doc blocks name a file once and then reference it as a bare `:NN`,
so every continuation reference went unchecked. Re-running the audit with
a resolver that carries the last-named file and directory forward finds
twelve stale line numbers and four references whose nearest named file is
the wrong one.

Fixed: the four `find`/`filter` lines and the layout equality tests under
the `views` requirement, the settings commit, the detail refusal throw,
and the three metadata guarded reads, all shifted by one to five lines.
The ui-state, paste-resolved and host-method references are now qualified,
because an intervening citation to another file silently reassigned them.

* test(mobile): re-pin the tasks parity hashes the round-2 fixes moved

One statement changed (the Linear list cast is gone) and three SAFETY
comments nested inside statements were rewritten, so the hook and
statement hashes move. Counts hold at 350 and 417, and the declaration,
semantic, render and style hashes do not move, which is what shows no
type, call or rendered tree changed with them.

`extractLinearIssueReadItems` lost its only caller when the smart-search
operation moved to `rpcResultVariant('linear-issues', …)`. What remained

a second 'Unexpected Linear tasks response' string competing with the
named reply error. The `LinearMobileIssue` type stays: it is the mobile
`LinearIssue` alias.

* docs(mobile): say what a refused sparse-preset list actually does to the screen

"Reports the named error" overstates it: the error setter's value is
destructured with a leading underscore and read by nobody, here and on
main. The visible delta is `presetsLoaded` staying false, which disables
"New preset" and both draft entry points where main let the user create

Brennan Benson abc8386e14 fix(mobile): name a create's launch so a lost reply cannot build two workspaces (#21137)
* fix(mobile): name a create's launch so a lost reply cannot build two workspaces

`agent.launch` admits a caller-supplied `operationId` through a durable ledger, so
exactly one execution happens and every replay returns the recorded answer. No client
sent one, so the machinery was inert and the original defect was still live: mobile
retries a lost create by design, and a retried launch built a second agent in a second
workspace.

Mobile now mints an operation id per create candidate and sends it whenever the host
advertises `agent.launch.replay.v1`.

The invariant is one operation per candidate. `computeAgentLaunchFingerprint` folds
`target` whole, so the workspace name is inside the fingerprint; carrying one id across
a name-collision bump would meet its own row under a differing fingerprint and refuse
`agent_session_operation_conflict`, failing the create outright on the second candidate.
The id is therefore minted beside `clientMutationId` at the top of each loop iteration
and reused verbatim by every retry arm inside that candidate — never re-minted, since a
new id is a new operation.

Admission runs ahead of every effect, so `_invalid` / `_expired` / `_capacity` prove
nothing launched: those re-send the same candidate unnamed rather than let bookkeeping
fail a create the host would have performed. `_unknown` is the one refusal that is not
safe to re-send, and it surfaces.

Also corrects a false comment: the legacy path caches the whole launch under
`clientMutationId`, so inside its 60s window a replay adds neither a workspace nor a
surface, and outside it adds both — not "a second surface, never a second workspace".

* fix(mobile): preserve launch identity on refusals

Jinwoo Hong 3e32b83522 refactor(mobile): checked reply readers for notifications, components, terminal, transport, home, worktree and browser (step 7) (#21176)
* refactor(mobile): checked reply readers for notifications, components, terminal, transport, home, worktree and browser (step 7)

Twenty-one unchecked reply readers across thirteen files become checked zod
readers, so a malformed host reply surfaces as one `RpcIncompatibleReplyError`
naming the method instead of a downstream `TypeError`, a rendered `undefined`, or
a card left "proven" over a reply that carried no rows. Deliberately a behaviour
change on malformed replies only.

What each domain required, and why it required no more:

- notifications (5 readers). All four call sites read the payload through `?.`,
  so every schema is nullish at the top level and no member is required. The
  test-push `reason` and the register `reason` become closed enums, because the
  two comparisons against them are the whole of what they decide and an arm this
  build does not know took the generic copy on main too. The stream unsubscribe
  and the unregister read no body at all.

- components (4). `repo.hooks` requires `source` and nothing else: the drawer
  assigns it straight into `SetupHookDetails.source`, whose type is
  `string | null`, with no guard in between — nullable so the "no hooks file"
  answer keeps its explicit null. `setupTrust` is nullable as well as optional
  because the `components-setup-ask` fixture sends an explicit null, and
  salvaging that would move a `normal` golden. `ui.get`'s trust record salvages
  per repo, so one unreadable repo cannot cost the others their approvals. The
  Codex redeem reply stays `z.unknown()`: `decodeResetResult` is a real
  scope-and-snapshot validator and splitting it would give one reply two refusal
  rules.

- terminal (4). The send verdict and the viewport pair keep main's exact
  `=== true` projections. `terminalSendAcceptedSchema` moves here from the
  session domain, which now re-exports it: terminal is the lower layer and two
  identical copies could drift on what "delivered" means.
  `terminal-send-rpc-response.ts` is deleted, its projection now being the
  schema's.

- transport (3). `status.get` declares its five members and requires the object;
  the three callers disagree about what an unreadable status means, so each keeps
  its own verdict behind a named reader — the gate wants the failure, and the
  probe and the pairing race must not have it, because both call `interpret`
  inside a `.then` fulfilment handler where a throw becomes a detached rejection.
  `capabilities` salvages whole rather than per element, which is main's own rule
  and what `transport-capability-probe-non-string-capabilities-drop` records.
  The two pairing readers are the shared credential contract itself, moved off
  the four call sites that each ran `.parse()` on the interpreted value; its
  `.strict()` is main's shipped rule for that released surface, not a new one.

- home (2), worktree (2), browser (1). The stats row is checked as an object and
  nothing more, `totalHomeStats` being the reader that says so itself; its
  per-host slot is now typed as the wire row it holds rather than as the computed
  total. `worktree.ps` cannot require `worktrees`: the host answers a union whose
  unchanged arm carries `{ unchanged, snapshotId }` and no rows. The twelve
  browser commands read no body; `browser.goto`'s settled URL stays nullish
  because `navigateToAddress` is inline in `MobileBrowserPane.tsx`, which no
  adapter mounts, and a move there would ship unevidenced.

Three fixtures were wrong and are corrected, each disclosed rather than worked
around: the runtime-context test kept a content hash directly under a repo key,
which is not a shape `ui.get` sends; and two snapshot-client tests ran their
reply list dry and handed `fetch` an absent result while claiming to model a
transport failure.

`push-test-envelope` is re-anchored at the same defect's new home, the cast
having been deleted. The boundary test's offender floor comes down from 20 to 10
with the list, which is what its own comment says it is for.

* test(mobile): repin the corpus and re-record step 7's checked reply readers

`baseline` moves to this branch's product commit, which is what `--record`
compares the fenced tree against, and every one of the 758 goldens is
re-recorded from it. The repin is what rewrites the `baseline` header on all of
them; nothing else about the corpus moves except the bodies disclosed below.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): mutate the workspace catalog's reader back to unchecked

The step-7 defect evidence needs a scenario whose reply is the one the change
moves. Every pilot scenario in the catalog family scripts a well-formed reply, so
a mutant that only changes how a *malformed* reply reads has nowhere to diverge —
which is why the pilot's own suite passed against an unchecked catalog reader
while its matrix golden failed.

`worktree-catalog-snapshot-unreadable` scripts `worktree.ps` answering
`{ ok: true }` with no result at all, which is what `result-absent` drives at the
matrix site, and records the fetch rejecting with `RpcIncompatibleReplyError`.
`worktree-catalog-unchecked-reader` then swaps the operation's reader for one that
answers `compatible: true` for every payload — main's reader, in one line — and
the recording moves back to a fulfilled fetch carrying
`admission: { kind: 'invalid' }`, which is the answer that let a broken catalog
render as an empty host (STA-3123).

One golden added and none moved: the manifest sits outside the fenced paths, the
family's matrix base is still `worktree-catalog-snapshot`, and the mutation
registry is not part of `recorderSha256`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the push-test reason arms the closed enum constrains

`pushDeliveryTestResultSchema.reason` closes over the four arms of the host's
`MobilePushTestResult` (src/shared/mobile-push-contract.ts:99), but no scenario
carried the member, so the corpus could not have caught a wrong vocabulary.
Three scenarios on the existing display-test mount carry it now: the two arms
the screen branches on and one arm no build knows.

Each golden was recorded first at the main pin 4b876758d3 and reproduces there
byte for byte, so the `normal` partition pins main's rendering rather than this
branch's. The unknown arm is the load-bearing one: main renders "Could not send
through Orca's push service." for an unrecognised string, and the salvage drop
renders the same sentence, so the closed enum costs a recorded `reply-salvage`
observation and no screen text.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): cite the host union behind each closed reply enum

A closed `z.enum` is only as good as the vocabulary it was checked against, and
mobile's own declared types are written from memory. Each of the three enums now
names the host type it mirrors, so the next reader re-checks it in one grep
rather than trusting the arms.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus to the commit that carries the host-union citations

`--record` compares the fenced tree against `baseline`, so a comment in
`mobile/src` moves the pin like any other product edit. Every one of the 762
goldens changes by exactly its `baseline` line and nothing else, which is the
evidence that the citation commit is inert.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the agent-history panel rendering when the catalog omits its rows

`worktrees` is a salvaged member, so it is absent on the three envelopes that
read as an object without rows, and `use-mobile-agent-history-state.ts:61` calls
`.find` on it with no guard. The cast erased that and the corpus recorded the
result: `matrix-aivault.history-screen-worktree.ps-1` carried
`crash: Cannot read properties of undefined (reading 'find')` on
`inner-ok-missing`, `inner-false-string-error` and `inner-false-object-error`.

`?? []` is what the sibling Home card already does. The SAFETY note cited that
card's golden, which is the opposite site, and now cites this panel's own family.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep a malformed worktree.ps reply reported as invalid_response

`host-workspace-list-states.tsx` prints this code to the user verbatim, so the
checked reader's throw landing in the generic catch renamed a host-payload
defect into a connectivity failure. STA-3123 exists to make a broken remote host
diagnosable, which `network_error` is not.

* refactor(mobile): give the browser page commands back their one-line form

Only `browser.goto` reads a reply body, so the reader belongs on a two-argument
wrapper rather than on all thirteen call sites. The exported type of every
command is unchanged, and the doc comment no longer promises a shape the file
did not have. 109 lines to 72.

* refactor(mobile): import the terminal send verdict from the terminal domain

The re-export forwarded to two callers, which a direct import already gives

* test(mobile): repin and re-record after the round-1 fixes

Three checkpoints of `matrix-aivault.history-screen-worktree.ps-1` move from a
recorded white screen to the loading list: `inner-ok-missing`,
`inner-false-string-error` and `inner-false-object-error` answer the panel an
object with no rows, and the `?? []` now seats an empty list instead of letting
`.find` throw. Every other golden changes by its `baseline` line alone, which is
the evidence the other four fixes move nothing the recorder observes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): stop requiring the stats row its own reader guards

Round-2 findings 1 to 3.

`homeHostStatsSchema` required an object that `totalHomeStats` already guards
(`if (!host || typeof host !== 'object') continue`), so the requirement bought
nothing at the read and cost the row upstream: the refusal reached
`fetchMobileHomeStats`'s `.catch`, the per-host slot was never written,
`hostIds.filter` found no host and the Home header drew no stats row where main
drew `0 / 0s / 0`. It takes `.nullish()`, and `HomeStatsRow` admits the
`null | undefined` main always had. The unit pin now says the slot keeps a null
summary and the total skips it, and sums one through `totalHomeStats` to show the
zeroed row survives.

The Home card's `SAFETY:` note claimed the reader proves `worktrees` is an array.
It does not; the `?? []` does. That is the same false sentence round 1 removed
from the agent-history panel, and a reader who believed it would delete the `??`
and reintroduce the white screen.

The `catalogError` branch on `RpcIncompatibleReplyError` had nothing holding it:
no adapter mounts the host screen, so no golden can reach it. One case in the
snapshot client pins the class the `catch` keys on. Mutation-checked by forwarding
the catalog schema as `z.unknown()`, which fails that case alone.

* test(mobile): repin and re-record after the round-2 fixes and main's merge

Pin moves to 0b8bd1c3c7, this branch's last fenced commit. The re-record
normalises the ten session create-terminal goldens main re-recorded in #20069
without repinning, and writes the Home stats family's bodies back to what main
records now that the summary reader no longer requires the object its own
consumer guards.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin and re-record the corpus at the merge with main

The merge took main's goldens verbatim at main's pin, so the four goldens this
branch adds were the only ones whose header did not name a commit in this
history. Repinning to the merge commit and re-recording gives all 764 one pin
and one recorder, which is what the new ancestry guard asks of the corpus.

* docs(mobile): point the reply schemas' citations at the lines they claim

Every `file:line` in this branch's diff was resolved against the tree and its
target line compared to the claim beside it. Fourteen were wrong. Most had
drifted one to four lines onto a closing brace or the line after the code they
quote, which reads exactly like a good citation and can only be caught by
resolving it.

Two were wrong in kind rather than by a few lines. The viewport comment
credited the `=== true` projection to the refit call site, which reads plain
truthiness; the rule was main's reader, and the refit's two decisions are the
lines now cited. The capability comment cited a line for main's
`every(typeof === 'string')` rule inside the code this change deletes, so it
resolved to an unrelated brace; it now states the behaviour and says why no
line carries it.

Two more pointed at the head or tail of the statement they named and are
tightened to the line that does the work.

Comment-only: no schema, no reader and no call site moves. The corpus is
repinned and re-recorded on top because the recorder fences `mobile/src`.

* test(mobile): repin and re-record after the citation fixes

The citation commit is comment-only, and the corpus says so: all 764 goldens
move on the `baseline` header line and nothing else. The re-record is needed
only because the recorder fences `mobile/src`, which a comment is inside.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep the three unguarded-site reply schemas total so a malformed result cannot throw where main tolerated it

The ui.get reader is interpreted inside a fire-and-forget IIFE with no catch, and the home
stats and push delivery readers sit behind handlers that would print the reader's own sentence
where main drew a zeroed row or the generic copy. Each schema now decodes any unreadable
result as absent, which lands in the fallback main already took.

Jinwoo Hong 01a1b6b024 refactor(mobile): checked reply readers for the tasks item and list domain (step 7) (#21169)
* refactor(mobile): checked reply readers for the tasks item and list domain (step 7)

Thirty-eight unchecked reply readers across four tasks files become checked zod
readers, so a malformed host reply surfaces as one `RpcIncompatibleReplyError`
naming the method instead of a downstream `TypeError`, a rendered `undefined`,
or a sheet left ready over garbage. Deliberately a behaviour change on malformed
replies only; nothing on the wire moves.

  mobile-task-item-state-operations.ts    17
  mobile-task-item-detail-operations.ts    8
  mobile-task-item-comment-operations.ts   7
  mobile-task-list-operations.ts           6

Two rules decide every schema, and both are stated in
task-provider-entity-reply-schema.ts:

1. A member is required only where a tasks consumer reads it with no guard.
   Everything reached through `?.`, `??` or a `typeof` test stays optional,
   because a reply without it rendered the same fallback then and now.
2. No member is required that the site's own recorded `normal` reply lacks. The
   corpus is the only evidence of what a host really sends at each site, and
   requiring a member absent from that control would turn a good reply into an
   incompatible one.

Rule 2 holds two schemas at the container: `github.prFileContents`, whose
recorded reply is `{ oldContent, newContent, truncated }` where
`getPRFileContents` returns `{ original, modified, ... }`, and `gitlab.todos`,
whose recorded row is not a `GitLabTodo` and whose `normal` partition therefore
records main crashing in `actionName.replace`. Both still gain their container,
which is what names a reply that is not an object or not a list. Correcting
those two scenarios is the follow-up that unlocks narrowing the rows.

Nine writes share one envelope reader and five comment writes share another:
`ok === false` and `error` are one host convention across them, and no input
would make two of them want different answers. The acceptance, the name and the
recorded family stay per operation. Three readers are reused rather than
re-declared — the session domain's boolean confirmation for `setPRFileViewed`
and `resolveReviewThread`, and its salvaged-member combinators throughout.

Three call-site shape tests the reader now answers for are deleted: both
`Array.isArray(payload)` guards on the checks read and the
`typeof count === 'number'` fallback on the item count. `GitHubPRFileContents`
is widened to optional members, which is what the reader can promise, and
`buildGitHubPrFileDiffPreview` takes the widened sides — `splitContentLines`
already treated a falsy side as no content, so no runtime behaviour moves.

The tasks source-parity hashes are refreshed: hook, statement, declaration and
render-token counts are unchanged, the render-token hash does not move at all,
and `semantics` is a pure deletion of ten lines.

Inventory: 137 unchecked readers over 30 files becomes 99 over 26.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the RPC recording corpus and re-record the tasks reply deltas

`baseline` moves to 9133c02c5b, the commit that made the tasks item and list
readers checked, and the whole corpus is re-recorded from it. The repin rewrites
the `baseline` header of every golden; the body moves are the disclosed
behaviour change and nothing else.

What moved, and why: a malformed reply at one of the thirty-eight migrated read
sites used to reach the consumer as the declared type and fail downstream — a
property read on `null`, `.map` on a string, a rendered `undefined`. It now
stops at the operation boundary as one `RpcIncompatibleReplyError` naming the
method, which each call site's existing `catch` shows where it showed the
`TypeError` before. Every move is confined to a malformed reply partition of a
`tasks.*` or `linear.issue-detail` family; no `normal` partition moves, and no
family outside the tasks domain moves at all.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): anchor the tasks reply readers' null-collapse mutant

One registered mutant for the class the session domain shipped twice before a
review caught it: the assignable-user row's explicit `avatarUrl: null` collapsed
into absence. `tk-item-detail-metadata` records that null in visible state, so
the pilot suite kills it; it also fails the unit pin beside the schema and both
of that family's matrix goldens, including their `normal` partitions.

Three by-hand experiments back the other two claims the corpus should hold.
Applied to the product source, run, reverted:

- Loosening a required member the consumer reads with no guard —
  `linearIssueSchema`'s `title` to a salvaged optional — fails the unit pin
  `one Linear issue: refuses a reply missing a member createLinearTask reads
  with no guard`, and `tsc` rejects it, because the loosened output is no longer
  a `LinearMobileIssue`. No golden moves: the reply matrix varies the envelope a
  host sends, never the shape of a row inside a result, so a row requirement is
  unreachable from the corpus and the unit pin is the only thing holding it.
- Loosening a *container* requirement is reachable: making
  `linearAccountStatusSchema` `.nullable()` fails one matrix golden,
  `tasks.provider-load: reply partitions at linear.status#1`, on the
  `result-null` partition, as well as its unit pin.
- Swapping one checked reader back to unchecked —
  `githubPullRequestChecksRead` to `rpcUncheckedPayloadReader` — fails two
  matrix goldens, `tasks.item-review-github` and
  `tasks.project-row-review-checks`, both at `github.prChecks#1`.

Nothing under `mutants/` is pinned by a golden header, so this moves no
recording.

* test(mobile): correct the gitlab.todos fixture to a real GitLabTodo row

The `tk-list-gitlab-todos` reply sent `[{ id, targetType, target: { … } }]`, a shape `listTodos`
never produces: the host returns `GitLabTodo[]`, whose row carries `actionName`, `targetTitle`,
`targetUrl`, `projectPath` and `updatedAt` flat. Main crashed on it —
`Cannot read properties of undefined (reading 'replace')` from `createGitLabTodoTask`, with the
list rendering as an empty inbox and a raw TypeError on screen.

That crash was being read as evidence: a reader could not narrow this row without "refusing the
site's only success control", when the control was never a success. The fixture is the defect, so
the fixture is what moves.

The row is now a real `GitLabTodo` (src/shared/gitlab-types.ts:219) and main renders it: one item
titled "A GitLab todo", subtitle `group/project #4`, status `review requested`.

Recorded from the pinned main tree, not from this branch, so the corrected fixture's main
projection exists as a golden before any reader touches it: a detached worktree at
`4b876758d3158a8eb6b798055d8db7c58d1cd4a9` with this branch's manifest laid over it and its
`baseline` set to that commit, per the recorder README's detached-pin recipe. Control: all 756
other goldens reproduced the base corpus byte for byte; only these two moved. Both keep
`baseline: 4b876758d3`, which is the tree that produced them.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): check the GitLab to-do row and drop its cast

With the fixture corrected, the row is readable, so the reader reads it. `gitlabTodoSchema`
requires the five members the screen reaches with no guard — `id`, `actionName` (read as
`actionName.replace`), `targetUrl` (what tapping the row opens, and the title's fallback),
`projectPath` (the subtitle and the repository badge's key and label) and `updatedAt` — and leaves
every guarded member optional: `targetTitle` behind `targetTitle || targetUrl`, `targetType` and
`targetIid` behind the two tests in `gitLabTodoTargetRef`, and `authorUsername` and `state`, which
this screen carries but never reads.

The list salvages: one unreadable to-do drops and the rest of the inbox still renders, which is
what the rest of this domain does with a row it cannot place. Nullish still reads as the empty
inbox the call site already read.

`GitLabTodo` in mobile-tasks-provider-detail-types.ts now says what the reader proves rather than
what the host declares, which is what lets the `as GitLabTodo[]` assertion at the call site go. It
was the last cast in this domain's consumers, and it was re-typing rows nothing had checked — the
phantom-field shape this series exists to remove.

Parity: the same three hashes the step-7 commit moved move once more, for the deleted cast and the
widened row type. Counts are unchanged and `semantics` does not move.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the corpus after the to-do fixture and row check

Repins `baseline` to the commit that checked the GitLab to-do row and re-records all 758 goldens,
so the whole corpus is pinned to one tree again: the two `gitlab.todos` goldens were still pinned
to main's, which is the tree that produced their before-picture.

The disclosed move is the `normal` partition of `tasks.task-list-gitlab-todos`. That is the fixture
correction showing through, not a reader change: with a real `GitLabTodo` on the wire the list
renders one item where it used to render a TypeError. Every other body move in this refresh is a
malformed-reply partition, as before.

* test(mobile): correct the github.prFileContents fixture to the host's shape

The recorded `normal` reply at both `github.prFileContents` sites was
`{oldContent, newContent, truncated}`, which `getPRFileContents` never returns:
it answers `{original, modified, originalIsBinary, modifiedIsBinary,
originalTooLarge, modifiedTooLarge}` (src/main/github/pull-request-file-contents
.ts:121-128), with the two too-large flags set only where a side was skipped for
size (:54). Both sites' `normal` partitions therefore proved nothing about the
success path, and `githubPullRequestFileContentsSchema` cited that fiction as
the reason it could require nothing. Same defect class as the `gitlab.todos`
fixture corrected in 32bd65c134, found by round-1 review.

Before-picture recorded against main's own product tree, not this branch's: a
detached worktree at `4b876758d3`, this branch's `pilot-scenarios.json` copied
in with `baseline` set to that commit, per the recorder README's detached-pin
recipe. Control: 744 of the 758 goldens reproduce the base corpus byte for byte;
the 12 copied here are the two affected families, and the remaining two are the
already-corrected to-do pair, which reproduced 32bd65c134's bytes exactly.

The 12 carry `baseline: 4b876758d3`, the tree that produced them. The next
commit's reader change and the repin that follows it re-record them.

* test(mobile): record main's reaction rendering for both providers

No scenario in the corpus carried a comment reaction, so nothing in the 758
goldens could see what a reader does to one. Round-1 review found the
consequence: this branch closed `reactions[].content` to a mobile vocabulary
(`thumbs_up`) that no producer sends, and the corpus stayed green because the
member was never on the wire.

Two scenarios, one per provider, each a second scenario in an existing family so
no matrix base and no existing golden moves. The GitHub one carries
`GitHubReactionContent` as the host sends it — `'+1'` and `'heart'`
(src/shared/github/comment-types.ts:3-17, normalised from GraphQL at
src/main/github/comment-reactions.ts:19-27). The GitLab one carries
`GitLabReaction`, which is `{ name, count }` with no `content` at all
(src/shared/gitlab-types.ts:60-72).

Recorded against main's product tree at `4b876758d3` through the detached-pin
worktree, so the `normal` partition now pins what main renders rather than what
this branch renders. Control: all 758 existing goldens reproduce the previous
pin recording byte for byte; the only difference is these two added files.

* fix(mobile): forward a comment reaction instead of matching mobile's vocabulary

`DETAIL_REACTION_CONTENT` was `thumbs_up | thumbs_down | ...`, a vocabulary no
producer of this list sends. GitHub answers `github.workItemDetails` with
`PRComment[]` whose reactions are `GitHubReactionContent` — `'+1'`, `'-1'`,
`laugh`, ... (src/shared/github/comment-types.ts:3-17), normalised from GraphQL
at src/main/github/comment-reactions.ts:19-27 — and GitLab answers with
`GitLabReaction`, `{ name, count }` with no `content` member
(src/shared/gitlab-types.ts:60-72). The closed arm set dropped every real
reaction row on both providers, which is a good-reply path this PR must not
change.

`content` is forwarded now, salvaged the way every other guarded member here is;
`count` stays required, because the `count > 0` filter at
mobile-tasks-item-comments.tsx:145 is the one unguarded read. `DetailComment`'s
eight phantom arms go with it: mobile's declared type was written from memory,
not from the wire, and widening the type is the fix rather than narrowing what
the host may send.

`COMMENT_REACTION_EMOJI` was keyed by that same phantom vocabulary, so it
resolves no glyph for a real reaction and the chip renders without one. That is
a pre-existing defect and it stays exactly as it is: the map is typed
`Record<string, string>` and the lookup takes `?? ''`, which resolves to the
same `undefined` main resolved for both providers. The two scenarios recorded in
68a3db2a3a pin that rendering, so a future arm set cannot drop the rows unseen.

* docs(mobile): stop citing the file-contents fiction as the reason nothing is required

The schema comment and its unit pin both named `{ oldContent, newContent,
truncated }` as "the recorded reply", which d26aeecdb0 corrected. The rule that
keeps every member optional is unchanged and is now stated from the reads
instead: the call site files the payload under the file path and reads nothing
off it, the review panels reach each flag through `?.`, and `splitContentLines`
takes `string | undefined` behind a falsy guard. The pins move to the host's own
shape, plus the too-large pair a skipped side carries and the empty object that
shows no member is required.

* refactor(mobile): import MERGEABLE_STATE instead of redeclaring it

`task-item-detail-reply-schema.ts` declared its own copy of `['MERGEABLE',
'CONFLICTING', 'UNKNOWN']` while already importing four member helpers from
`../session/github-pr-entity-reply-schema`, which exports that arm set and uses
it in the identical expression three times. Two copies of one wire arm set is
one place to fix when a provider gains a fourth state.

* refactor(mobile): inline the alias-only bindings the deleted casts left behind

Each of the eight was `const result = x as { ok?: boolean; error?: string }`.
With the cast gone the line is a rename of a binding that already has a name,
and every one of them is followed immediately by the same `ok === false` check.
Reading `created.ok` / `updated.ok` / `written.ok` / `replyResult.ok` directly
leaves one name per value.

The parity constants move with it and with the reaction change before it. The
comment there names both: ten string literals leave `semantics` with the phantom
reaction vocabulary and one arrives with the `?? ''` fallback, and the alias
deletions move the hook and statement hashes. No `rpc:` or `jsx:` signature
moves, the render-token hash does not move, and the hook, statement and
declaration counts are unchanged at 350, 417 and 194.

* test(mobile): register the container-requirement mutant the matrix kills

`f1b695f161` proved by hand that making `linearAccountStatusSchema` `.nullable()`
fails the `result-null` partition of `tasks.provider-load`'s matrix, and left it
unregistered. Registering it in `pilot-mutants.test.ts` is not available: that
suite drives the manifest scenario as written, and `tk-provider-load` scripts a
fulfilled `linear.status`, which a nullable container accepts exactly as the
required one does. The mutation only has somewhere to diverge under a partition
the pilot never reaches.

`family-mutants.test.ts` drives one named variant of a family's matrix instead,
against that variant's own slice of the golden, and each entry names both the
partition that kills the mutation and one that cannot see it — so the entry
records where the coverage is rather than that some golden went red. The
comparison is the whole recorded variant, the way the family suite compares:
under a last-state projection this mutant survives, because the divergence is in
the settlement and both paths reach the same final screen state.

Nothing under `mutants/` is pinned by a golden header, so this moves no
recording.

* test(mobile): repin the corpus after the round-1 review fixes

`baseline` moves to 542c1c38ed, the last fenced commit, and the whole corpus is

scenarios were recorded at main's pin first, so this run is what carries them
onto the branch's own reader.

* refactor(mobile): keep the Linear create arm's own binding out of the inlining

The alias inlining swept one line further than the finding it answers: the
Linear arm's `const result = linearIssueCreate.interpret(reply)` is a
declaration with a name, not an alias for one, and renaming it put a
pre-existing `createLinearTask(...) as Extract<TaskItem, …>` assertion from
#17438 inside this branch's changed lines, where the changed-code casting gate
attributes it to this PR. Reverted to `result`; the eight bindings the review
listed stay inlined.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): let each module build its own Linear team reader

`linearTeamListReader` was exported from the detail-operations module only so the
list-operations module could import it, which adds an operations-to-operations
import edge that buys nothing: `rpcResultVariant` is a pure factory, so two calls
with the same schema produce two functionally identical readers. What keeps the
composer's picker and the saved-selection reconciler agreeing about a team row is
that both build from `linearTeamsSchema`, which is already exported.

Deleting the export also puts the composer-policy JSDoc back on
`linearComposerTeamListRead`. JSDoc binds to the next declaration, so the block
explaining why this method carries two operations with different acceptance
policies had drifted onto the reader, leaving the operation it is about
undocumented.

`baseline` moves to 75c568c244 and all 760 goldens are re-recorded against it.
Nothing but the `baseline` header moves: the two product commits since the
previous repin — the Linear create arm's binding restored and the team reader
built per module — change no observation in any recording, which is what a pure
refactor should look like here.

* chore(mobile): repin the RPC recording corpus to the main merge

The merge of origin/main moved both lockfiles, which the recorder fences,
so --record refused until the pin named a commit whose fenced tree matches

only, `baseline` and `lockfileSha256`. No observation moved.

* docs(mobile): point the reply-schema citations at the lines they name

The alias inlining and the detail-loader rewrite moved fifteen of the consumer
lines these comments cite, and the comments are the evidence for requiring a
member only where the consumer reads it unguarded. Every citation re-checked by
opening it; the host-side ones were already right.

* docs(mobile): stop repeating the file-contents fiction on the type

The corrected fixture carries four of the six members at both call sites, so
"the recorded reply carries none of these" is false. The reason is the one the
schema already gives: no reader reaches a member without `?.` or
splitContentLines' falsy guard.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): forward a file's viewed state instead of closing it

No scenario reply carries a file row, so no golden can observe either of this
schema's two arm sets. `viewerViewedState` is read only by two `=== 'VIEWED'`
tests, so it is forwarded and an arm this build predates reaches them as itself.

`status` stays closed: its only consumer sends it straight back as a
`github.prFileContents` param, which the host validates against the same seven
arms (github-pull-request-params.ts:62). Forwarding could not reach the wire
without a cast, and the host would refuse the arm on its own params, so the
drop to absent that becomes `?? 'modified'` is the compatible read.

Parity: one declaration and three arm literals, no executable change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say that a Linear state-update refusal is ignored, as on main

`require-result-or-throw-message` throws only on an outer refusal, and
`linear.updateIssue` refuses in band as `{ ok: false, error }` on a
successful envelope, so the refusal reaches no `catch`. Main read the
same payload unchecked and discarded it, so nothing here changes.

Main's #20069 re-recorded ten session create-terminal goldens and moved
twenty-one files under src/shared, both inside the recorder's fence, so

`baseline`, in all 760 goldens and nothing else; the ten taken from main
reproduce byte-for-byte apart from that pin.

Brennan Benson e42f7c00bd feat(native-chat): render a proposed plan as a plan, not a generic approval (#21090)
* feat(native-chat): render a proposed plan as a plan, not a generic approval

A finished plan arrives as an ExitPlanMode tool call. With no handling for
it, the generic approval path serialized the tool input, so a plan appeared
as thousands of characters of escaped JSON. A plan is content to read, not a
privilege to grant.

Classify the plan in the permission callback and carry it as a typed subject
on the approval item, keeping the existing approval kind so the prompt still
reaches every consumer. Mobile filters pending approvals on that kind, so
introducing a new one would have made the prompt vanish there silently.

Classification runs before registration, so a future permission-mode
short-circuit cannot swallow a plan proposal. The assistant tool-use stream
is a second ingress and is pinned by its own test, because neither path can
be assumed to fire on its own.

Rather than adding a second card, the plan renders inside the approval
card's existing bounded content region. It inherits the height cap, the
scrolling, the keyboard focus and the pinned action row that region already
provides, and a typed plan replaces the raw detail instead of rendering
both. Buttons read as plan decisions. Mobile renders the same subject
through its own markdown component in the same region.

Brennan BensonandMerge Sim 5287c5cdbc fix(mobile): stop a created tab from jumping when the host snapshot lands (#20069)
* fix(mobile): stop a created tab from jumping when the host snapshot lands

Creating a tab from the mobile session strip painted the new tab at the end
of the strip and then visibly jumped it to a different slot a beat later.

The client asked the host to insert the tab after the active tab, but then
predicted a different placement for its own optimistic paint:

    afterTabId: activeSessionTabId ?? undefined   // host: splice(insertAfter + 1)
    ...
    return [...prev, { ...created, isActive: true }]   // client: append

Two independent placements that disagree, so the optimistic frame is wrong by
construction and the tab snaps to its real slot on the next published snapshot.

The disagreement dates to 57a70d2ac0 ("Fix mobile session tab authority"),
which introduced afterTabId and left the append in place. Before that the
client used terminal.create with no anchor, so both sides appended and agreed.

Rather than teach the client to re-derive the host's rule, both sides now call
one shared placeCreatedSessionTab, and the client captures a single afterTabId
for the request and the paint so they cannot drift apart again.

The host change is a pure refactor onto the shared helper; the 1260-test
runtime characterization suite is unchanged. The mobile route-parity hash pin
moves once because handleCreateTerminal's body changed - it is the only one of
the 12 extracted functions that differs.

* fix(mobile): negotiate split tab placement

Neil 6c3b97b950 fix(mobile): a scope refusal is not a missing method on the Relay pairing probes (#19952)
* fix(mobile): a scope refusal is not a missing method on the Relay pairing probes

The desktop's mobile allowlist gate runs before its RPC dispatcher, so a method an
older desktop predates is absent from both and the phone is answered `forbidden`,
never `method_not_found`. Keying the "too old for Relay, stay on LAN" fallback on
`method_not_found` alone therefore never fired against the exact desktop it exists
for: first-time pairing threw instead of committing a LAN host.

`isPairingRelayRpcUnavailable` accepts both codes at the three pairing probe sites.
It is pairing-scoped on purpose - `isMethodNotFoundRefusal` has four other consumers
that must keep reading `forbidden` as a refusal, not as absence.

The main-side test pins the claim the fallback rests on: the dispatcher really does
answer `forbidden` to a mobile-scoped device and `method_not_found` to a runtime one,
and this build allowlists both probes, so `forbidden` on either can only mean an
older desktop.

* fix(mobile): leave a breadcrumb when a desktop refuses relay pairing

The LAN fallback now commits a host instead of throwing, so the refusal code
was the only record of why a phone ended up without a relay endpoint and
nothing wrote it down. Log it on the path that swallows it.

Narrow `isPairingRelayRpcUnavailable` to the two codes it matches rather than
to `RpcFailure`: a plain failure guard would collapse the *false* branch to
`RpcSuccess`, which a refusal carrying any other code still reaches.

Rename the `'method-not-found'` sentinel in the direct-upgrade reader, which
stopped describing what it covers, and correct two comments that named a
`method_not_found` mechanism the desktop cannot produce for these methods:
both probes have been allowlisted and registered by the same commit since
Relay landed, and an unwired pairing provider answers `runtime_error`.

* docs(wire): record that the mobile surface refuses by scope, not by absence

Two comments cited this page for "a scope refusal is not a missing method" and
the page did not say it — the only nearby statement says the opposite, because
it describes the runtime-scoped surface, where the dispatcher does answer
`method_not_found`. The allowlist gate makes the mobile surface the exception,
and the harness does not run that surface, so this note is the only record.

* docs(mobile): name the pairing site the scope refusal actually reached

The comments and the wire-compat note said this fixed first-time QR pairing.
It cannot: the `relay` block on the pairing offer, both RPC handlers and both
allowlist entries all landed in 77b154d5dd, so a desktop old enough to refuse
the probe also omits the offer block, and that flow commits a LAN host without
ever probing. The site that reached is `upgradeDirectMobileRelay`, which
re-probes every LAN-only host on reconnect: the refusal threw into the
controller's swallowing catch, so the write-once journal it had just written —
and the pending resume secret in it — was never retired.

Also drop two overclaims: the phone's Files and Git fallbacks have read both
codes since they shipped, so this is settled practice rather than a new rule,
and the reason the allowlisted-but-unregistered case cannot ship is
mobile-rpc-allowlist.test.ts, not a convention about what lands together.

Jinwoo Hong 4b876758d3 refactor(mobile): checked reply readers for the session domain (step 7) (#21089)
* test(mobile): record main's session reply behaviour at every unrecorded read site

Step 7 for the session domain changes how 51 RPC readers read a *malformed*
reply. Eleven of the session read sites had no recording family, so main's
answer to a malformed reply at those sites was undocumented and the reader
change would have had nothing to move. This commit is the before picture, taken
from main's own tree with no product edit in it.

Ten new families, twelve scenarios, twenty-five goldens:

- `session.review-file-diff` / `session.review-branch-diff` — `git.diff` and
  `git.branchDiff` read through the review projection, which the Changes
  screen's verbatim readers do not cover.
- `session.review-git-mutations` — the single-file `git.stage` / `git.discard`
  and the bulk stage sweep's second `git.stage`.
- `session.review-send-sheet` — `session.tabs.list` read for the agent
  terminals the send sheet lists, the third reader on that method. Needs an
  `open-send-sheet` action on the review-action adapter, which re-digests that
  family's eight goldens on `adapterSha256` and nothing else.
- `session.browser-tab-create` — `browser.tabCreate`.
- `agentSession.structured-create` — `agentSession.create`, whose family base
  only ever covered the support probe.
- `session.tab-rename` / `session.tab-close-session` — `terminal.rename` and
  `session.tabs.close`.
- `settings.new-tab-local-agents` — `preflight.detectAgents`, the arm the
  new-tab loader takes for a workspace with no connection.

`baseline` is repinned to main's tip because two commits (#20659, #21004)
touched a fenced path after the pilot's pin, so `--record` refuses on main's own
tree until it moves. The repin is what rewrites `baseline` on all 705 existing
goldens; nothing else about them moves.

Decoded against origin/main through the value pool: 705 header-only (`baseline`
on every one, `adapterSha256` on the eight review-action goldens), 0 body-moved,
25 added, 0 deleted.

Not covered, with the reason: the chunked clipboard upload's
`appendImageUploadChunk`, `commitImageUpload` and `abortImageUpload` cannot be
matrixed, because `replyMatrixSites` takes every completion in the base scenario
and the chain's later params carry the `uploadId` the start reply named. Driving
`clipboard.startImageUpload#1` therefore makes main send an append whose params
no scripted step matches, and the recorder raises `Request params mismatch:
clipboard.appendImageUploadChunk#1` instead of recording. The two families were
written, probed and removed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): checked reply readers for the session domain (step 7)

Fifty-one unchecked reply readers across nine files become checked zod readers,
so a malformed host reply surfaces as one readable error at the operation
boundary instead of a downstream `TypeError`, a rendered `undefined`, or a
screen left ready over garbage. Deliberately a behaviour change on malformed
replies only.

Eight schema modules, one per reply family, each recording the consumer line
behind every requirement and the host handler that publishes it:

- `clipboard-image-reply-schema.ts` — the upload slot's `uploadId`, the commit
  and single-frame path strings, and the two legs whose body nothing reads.
- `github-pr-mutation-reply-schema.ts` — the `{ ok, error }` status envelope as
  two variants, and the bare-boolean confirmation.
- `github-pr-entity-reply-schema.ts` / `github-pr-read-reply-schema.ts` — the
  seven PR sidebar reads. Every identity requirement the hand parsers had is
  kept, so a payload that degraded to null still degrades to null; what changes
  is a payload that is not the declared container at all.
- `diff-review-reply-schema.ts` — the normalized branch compare, the review
  notes on the worktree record, the three file-diff arms, and the file-level git
  mutations.
- `review-terminal-reply-schema.ts`, `session-launch-reply-schema.ts`,
  `session-read-reply-schema.ts`, `session-write-reply-schema.ts` — the review
  send sheet, the launch paths, the session screen's reads and its writes.

Requirements are exactly the members a consumer reads unguarded, everything else
is a salvaged optional with main's own default applied in the transform, and no
schema is `.strict()`: a member a newer host adds passes through untouched.
Enum arm sets that a reader compares against pass through or degrade to the arm
the reader handles most conservatively; the two closed sets — the committed
change status and the diff kind — are closed because main *dropped* an arm it
did not know rather than passing it through, and degrading them would draw a row
or render a diff main never did. No member is coerced on the way back to the
host.

`github-pr-parsers.ts`, `github-pr-comment-parsers.ts` and
`github-pr-value-readers.ts` are gone; their suite is now the parity record for
the schemas that replaced them, with the four cases that refuse rather than
degrade marked as such. Twelve call-site casts are deleted, and three dead
"response was invalid" branches with them: the reader refuses those replies now,
so the error names its method.

The nine session files come off `unchecked-rpc-reader-inventory.ts` entirely
rather than being lowered. `git show --stat` on this commit touches nothing
under `mobile/rpc-foundation`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): unit-pin every session reply schema's decision

Three kinds of case, one per kind of decision the schemas encode: a member a
consumer reads unguarded is required and its absence refuses, an arm set a
reader compares against degrades to the arm that reader handles most
conservatively, and a reply whose arms need different members is declared as
variants and each arm is read.

The last suite is the wire-compatibility claim: a member no reader knows passes
straight through, on the markdown document, the upload slot and the terminal
inventory alike, so a newer host is never refused for a field mobile does not
read.

* test(mobile): refresh the corpus for the session domain's checked readers

Repins `baseline` to the last commit touching a fenced path and re-records all
730 goldens, which is the disclosed behaviour change taken as an observation.

Decoded through the value pool against the pre-refactor tree on this branch:
688 header-only with `baseline` the only key that moved, 42 body-moved, 0 added,
0 deleted. The 42 are seven named scenarios and thirty-five matrix goldens, and
every moved checkpoint's own reply is malformed or refused. Three `normal`
partitions appear in the list and none of them reads a well-formed reply
differently: the review file-diff family's base scenario drives three legs and
its third is scripted `{ kind: 'unknown' }`, so that leg's checkpoint moves in
every variant, the varied leg included. The same append-only-history effect puts
`pr-read-upstream-error`'s `no-pr` checkpoint in the list for the malformed PR
recorded before it.

What the corpus now records, in one sentence: a property read on null, a V8
destructuring message shown to the user, and four hand-written "response was
invalid" strings are replaced by one message that names the method, and four
screens that published a malformed payload as ready state now show an error
instead.

* fix(mobile): contain a refused prChecks reply to the checks section

The checks read was the one phase-1 dependency that could take the whole PR
sidebar down. `loadPrSidebarData` routed `!checksOutcome.ok` through
`failureState`, so a host whose `github.prChecks` shape drifted cost the user
the title, body, comments, reviewers and merge controls — everything they
opened the sidebar for — over a section that renders a row of icons. Main
never noticed because its unchecked reader answered `[]` for the same reply;
this branch's reader refuses it, which is correct, and which is what makes the
containment necessary.

Contained the way phase 2 already is: a failed read keeps `kind: 'ready'`,
empties `checks`, and carries the message in a new `checksError` so the checks
section can say what happened. The sidebar can no longer reach `error` or
`blocked` on the checks read alone.

Also pins the enum departure this PR makes deliberately. The degrading arm
sets go through `salvagedOptional(name, z.enum(...))` rather than `openEnum`
because `openEnum` refuses a non-string where main mapped it to the
conservative arm; nothing held that, and all 2477 tests stayed green against
the swap. Six cases now hold both halves: a non-string degrades on the three
open sets, and an unknown arm drops the row on the closed ones.

Four deletions the reviewer found: a reaction-token alias with no importers,
the `errorType`/`fetchedAt` the branch-lookup reader fabricated to satisfy a
type whose only consumer reads neither, two bare schema aliases, and a
quick-commands pass-through with two callers.

* test(mobile): repin the corpus to the containment commit

`--record` refuses unless the product tree equals `baseline`, so the fix above
moves the pin. The corpus re-recorded in place against it: 730 goldens, every
one header-only on `baseline`, no observation moved.

No observation moved because no family reaches the code the fix changed. The
`github.pr-read` family calls the seven wrapper reads directly and records
their `{ ok, error }` outcomes; `loadPrSidebarData` sits a layer above that and
no scenario mounts it. The prChecks outcome is identical before and after —
what changed is what the sidebar does with it — so the unit suite is the only
oracle for the containment.

* test(mobile): record the PR sidebar's checks containment

The containment landed with no golden: no scenario mounted `loadPrSidebarData`,
so the row in the delta table rested on unit tests alone. `PrSidebarLoadDeps` is
five client-taking functions, so a new adapter drives phase 1 directly and
records the `PrSidebarState` it resolves to — no React host, and no edit to an
existing adapter, so no recorded golden moves.

Two scenarios: a normal load, and one whose checks leg answers a shape the
reader refuses. The matrix over the base then drives all eleven partitions at
`github.prChecks#1`, and every one of them records `ready` with a `checksError`
where main took the whole sidebar to `error`. `pr-sidebar-checks-failure-state`
is the mutant that routes the refusal back through `failureState`; it moves both
`pr-sidebar-checks-refused` and the prChecks matrix golden.

Also pins two closed-and-required enum decisions that were free to become
defaults — an unknown check-summary state drops the summary block, an unknown
reaction content drops the reaction — deletes four exported type aliases and
five enum constants with no reader outside their own file, makes
`PRChecksSection`'s `checksError` required so a second caller cannot silently
lose the message, and stops the header reading "No checks" when the checks were
unreadable rather than absent.

* test(mobile): repin the corpus to the pr-sidebar family commit

Six new goldens — two pilots and the four matrix sites the base scenario
scripts — and `baseline` on the 730 that already existed. No body moved and no
`adapterSha256`: the family is a new adapter module, so nothing recorded through
another one re-digests.

Repins `baseline` to the merge commit and re-records all 736 goldens in
place. Against `origin/main` the 705 shared goldens move only on
`baseline` (672 of them header-only), leaving the same 33 body moves and
the same partitions the branch carried before the merge, plus its 31
added goldens.

Every body also takes main's recorder shape from #21088: `sent` becomes
`ordinal` over one interleaved write counter, subscriptions record a
cleanup checkpoint, and a salvaging read now reports a `reply-salvage`
effect naming what it dropped.

* fix(mobile): keep an explicit null on the two tri-state PR flags

`autoMergeAllowed` and `mergeQueueRequired` carry three answers, not two:
`null` is GitHub saying auto-merge is not allowed, `undefined` is the host
not carrying the member at all. The readers coalesced the null away, so a
well-formed reply read differently from the parsers they replaced, which
preserved it explicitly. Both shared types already declare `boolean | null`.

No consumer separates the two today — `pull-request-auto-merge-availability`
compares with `=== true` and `!== false` — so this is parity, not a visible
fix, which is exactly why it needed a test.

* refactor(mobile): check the two session-write readers #21083 brought

Step 7 empties the session block of the unchecked-reader inventory, and
#21083 landed two readers into it after that: the New Tab create's member
read of `tab`, and the display-mode toggle's payload. Converting them is
what keeps the claim true — a session line reappearing would mean the
domain is not migrated.

`created-terminal-tab` requires `tab.id` and `tab.type === 'terminal'`,
because the strip keys the new tab on the id and spreads the rest into a
union whose arm `type` picks. `terminal`, `title` and `terminalTheme` stay
optional behind main's own guards, and unknown members pass through.
`terminal-display-mode-set` reads nothing, so it takes the same
`z.unknown()` the other five unread writes take.

* test(mobile): repin and re-record over #21083's corpus

All 736 goldens this branch already had move on `baseline` alone, and
#21083's 22 arrive beside them. One of the 22 moves against main's own
recording: `matrix-session.create-terminal-session.tabs.createterminal-1`,
where the New Tab create's five malformed partitions read
`Cannot read properties of undefined (reading 'tab')` and now read the
method's own message. Two of them also stop unsubscribing the terminal the
user was watching before the property read threw, so a create that never
happened no longer costs the live pane its subscription.

Brennan Benson aad41b1a40 fix(native-chat): render approvals from the harness presentation, not serialized tool input (#21087)
* fix(native-chat): render approvals from the harness presentation, not serialized tool input

The approval card built its title from the tool name and rendered
JSON.stringify(input) into an element with no height bound. Any large
payload - a file write's contents, a proposed plan - pushed the action
buttons past the viewport with no way to scroll to them, leaving the
prompt unanswerable without zooming the pane out.

Thread the agent SDK's own presentation fields through the prompt
registry into the journal item: title, displayName, description,
decisionReason, blockedPath and matchedAskRule. The SDK documents its
title as the prompt text to use instead of reconstructing one, and
warns that the decision reason may carry terminal escapes, so those are
stripped before rendering. The card now also shows why a request was
raised rather than only what it was.

Bound the detail in a scrollable region that is reachable by keyboard,
and cap it main-side with the existing shared tool-detail limit rather
than the far looser journal payload bound. Focus moves to the card when
a prompt appears and Escape resolves it, which previously did nothing
because the composer owning that handler is unmounted while a prompt is
pending.

Mobile rendered the same unbounded detail and is fixed alongside.

Jinwoo Hong ccb4d2044b refactor(mobile): send the last session-route raw-port calls as operations (step 6, migration 2) (#21083)
* test(mobile): record the session startup, create and display-mode families

Three mount adapters and ten scenarios for the last raw-port sends in the
session route, recorded at the pinned main baseline before any product edit.

The three hooks were listed as blocked on a WebView-ref substitute. They are
not: none imports the terminal WebView, and all three send with no ref. The
display-mode toggle reads a `{cols, rows}` cell and a device-token cell; the
create path calls scope callbacks; the startup effect drives scope callbacks
only. Each stub is an effect sink, shapes no param and swallows no throw.

One scenario reaches both `worktree.activate` sites the way the product does:
the auto-create clears `created` off the route, the effect re-runs on the same
mount and takes the other branch, so the reply matrix drives both.

The create adapter mounts in its factory rather than as a scripted step. React
draws one `Math.random()` lazily the first time `enqueueTask` runs, and the
runner flushes through `await act` after every step, so a scripted mount would
make `clientMutationId` the second draw of the seeded sequence on the first
recording in a process and the first on every later one. The two determinism
runs caught it.

Recorded through the pinned-baseline worktree recipe, because main has moved
past `a28085adbf` in `src/shared` and this branch does not repin. 705 existing
goldens byte-identical, 15 added, 0 moved, 0 deleted.

Mutation census against the raw-port code, applied and reverted by hand, all
twelve killed: wrong method at each of the four sites; acceptance verdict
swapped at each of the four verdict-reading sites; dropped `unsubscribeTerminal`
on replace; the two activation branches swapped; a delayed `fetchTerminals` pass
dropped; the viewport pair not forwarded on `terminal.setDisplayMode`.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): send the last session-route raw-port calls as operations

Four references, three files, no behaviour change. Proven by replay: the
fifteen goldens recorded at the pin before this commit pass unchanged, so no
re-record.

- `use-mobile-session-startup.ts` both `worktree.activate` sends reuse
  host-screen's `worktreeActivate`. Its skip verdict was never read before;
  the startup effect is its first reader, and it reads exactly what main read
  off the envelope — whether an accepted reply says the host is headless.
- `use-mobile-session-terminal-create-actions.ts` `session.tabs.createTerminal`
  gets `sessionTabCreateTerminal`, a single-reader operation beside the other
  session-screen writes. `require-result-or-throw-message` replaces the
  `if (response.ok)` branch because the throw lands in the catch that already
  reported the host's message, character for character, including the empty
  message falling back to the screen's own copy. The reader stays the unguarded
  `.tab` read, because that policy rethrows a reader's exception rather than
  converting it, which is what keeps a null or absent result failing where it
  failed before.
- `use-mobile-session-terminal-stream-display.ts` `terminal.setDisplayMode` gets
  `terminalDisplayModeSet`, a skip whose verdict the caller does not read, the
  way `terminalBufferClear` already works: the server does the resize and
  reports it on the terminal's existing subscription, so main looked at nothing
  in the envelope and only a transport rejection was ever a failure.

The prompt `terminal.send` in the create path stays on the raw port. It is the
only `terminal.send` caller that falls back to its own copy when the host
refuses with an empty message, so no existing operation carries its acceptance
and a new one is a fourth method outside this migration's scope. It is recorded
either way.

* test(mobile): lower the raw-port inventory and refresh the session route pins

Pending raw-port inventory: two entries deleted and one lowered, 12 files / 21
references to 10 / 17. The startup and display-mode entries reach zero; the
create entry keeps the prompt `terminal.send` and states its own reason.

Three stale comments corrected. The startup, create and display-mode entries
claimed a WebView-ref or subscription wall that measurement did not find: none
of the three hooks imports the terminal WebView, the display-mode write is not
gated on an open subscription, and the create path's `subscribeToTerminal` is a
scope callback rather than a `client.subscribe`. The accounts screen's entry
said the runner is request-only, which stopped being true when `ScenarioStep`
gained `frame`; what actually blocks it is that no scenario has been written for
`accounts.subscribe`, so its entry now says that instead.

Unchecked-reader inventory: `mobile-session-write-operations.ts` 8 to 10 for the
two readers the migration added, named in the header the way #20954's three are.

Route parity: four pins refreshed with their reasons — the callback bodies for
the display-mode toggle, the effects for the startup activation pair, the nested
function bodies for the create, and the runtime strings, whose count falls 535 to
531 as four more method literals move to their operations' definitions. The
startup source pins now name `worktreeActivate` and still hold what they held:
the plain activation is fired rather than awaited, and it goes out before the tab
load.

* docs(mobile): say which part of the display-mode operation no golden holds

Post-refactor census survivor, measured rather than assumed: swapping
`terminalDisplayModeSet`'s acceptance for `require-result-or-throw-message`
moves none of the fifteen goldens. The call site reads no verdict and its own
`catch` swallows a throw either way, so no policy is observable there. The
method, the params and the viewport pair are what the goldens hold at that site.
The six other operation-level mutations all kill.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record the empty cells the session guards are written for

Three session sends are gated on a cell every existing scenario filled: the
display-mode toggle carries `viewport` only once a surface has measured one and
`client` only once the phone holds a device token, and the startup sequence
swallows a refused tab load before loading terminals behind it. Every recording
declared those cells full, so the arm each guard exists for was never on the
wire and dropping the guard moved no golden.

The two device cells become scenario arguments rather than adapter constants, so
a scenario can declare them empty; the tab load may now be declared to reject,
which is the only way a refused scope callback is reachable at all. Declared, not
shaped: the stubs build no param and swallow no throw.

Three scenarios take the empty arm. The token and viewport ones send `auto`,
which is the direction both members ride, and the startup one records that the
terminal loads and the activation timer still run behind a refused tab load.

Recorded at the pinned baseline through the detached-pin worktree recipe, since
this branch may not repin. 705 goldens identical, 0 body moved, 3 added, 0
deleted; the 15 header-only moves are `adapterSha256` on the three edited
families and `scenarioSha256` on the four scenarios that now declare their token.

The create adapter's determinism comment now names the draw it works around:
React's lazy `("require" + Math.random())` in `enqueueTask`, the scheduler line
that seeds the sequence, and the mismatch a misplaced mount reports. #21088
retires the workaround.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): witness the three session guards the recordings had not pinned

Each mutation is the guard deleted: the display-mode send carries `client` with
an empty id, carries `viewport` before anything measured one, and the startup
sequence lets a refused tab load reject it so the terminal loads and activation
timer behind it never run. All three survived the whole suite before the
scenarios above; the witness asserts each is killed by its scenario and that
every other scenario of the same family still cannot see it.

A mutation that changes a param the scenario completes aborts at the transport's
params assertion instead of producing a divergent recording. That is the
scenario detecting it, so the witness reads that one message as a kill, narrowed
to it and taken only after the anchor is proved applied.

The README gains the class as its fifth bounding fact: a value an adapter holds
as a constant is a cell no scenario can empty, so the arm that reads it empty is
unreachable until the constant becomes an argument. Corpus counts refreshed to
what the suite measures.

* refactor(mobile): drop the terminal-create result type nothing reads

`TerminalCreateResult` wrapped the created tab for the old `sendRequest` reply
shape. The migrated call site reads the tab off the operation and names the tab
type directly, leaving the wrapper with zero readers repo-wide. Using it at the
cast site would have kept the cast and only renamed it, so it goes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): let the create scenarios declare what the create puts on the wire

The terminal-create adapter decided four of the members its own goldens hold:
the worktree, the tab a new one is inserted after, and every launch option but
the prompt and its two toasts. A value an adapter supplies itself is a cell no
scenario can empty, so `afterTabId`'s omission arm — the arm a fresh session and
a last-tab close both take — was unreachable, and the quick-command members were
recorded only as absent. All of it now comes from the scenario, and the mount
moves to the first action so the arguments are in place before the hook reads
them. It stays out of a scripted mount step for the determinism reason above it.

Four scenarios follow the new arguments: a create with no active tab, a shell
quick command, an agent quick command, and a second tap while the host is still
answering the first. The refused scenario stops declaring an `errorToast` the
adapter dropped: forwarding the toast independently of the prompt is what the
product does, so that golden now records the failure toast it always showed.

Recorded at the branch's pin, so 705 goldens stay byte-identical to the merge
base; five headers move on adapter and scenario digests and one body moves, the
refused create's new toast effect.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): witness the three create guards the recordings had not pinned

Each of the three new create scenarios closes a mutation that survived all 853
tests before it: putting the active tab on the wire as `null` instead of
omitting it, swapping the `command` and `agentPrompt` members the host reads,
and dropping the in-flight guard so a second tap opens a terminal nobody asked
for. The witness asserts the hole and the closure together, as the others do.

The params-mismatch abort the witness reads as a kill now rests on an assertion
rather than on an argument: no scenario in the manifest completes a request
after its last checkpoint, so a send whose params stopped matching always
suppressed an observation a golden holds.

Known-open holes loses its prose count and becomes a list that names the site,
the mutant and why no scenario can see it. Two entries join it: the display-mode
acceptance, which no call site reads, and the startup timer's attached-terminal
guard, which needs an adapter that can attach a terminal mid-scenario.

* refactor(mobile): interpret the activation reply where it is reported

`reportActivationOutcome` took a verdict, which left the timer site hand-building
`{ accepted: false }` for the case where there is no reply to interpret at all.
Taking `RpcResponse | null` and interpreting inside puts the operation's own
policy at both sites and spells the absent reply as absence. Nothing is lost:
`worktreeActivate` reads an unchecked payload and admits every success, so its
`interpret` cannot throw on a reply either site can receive.

No golden moves; the effect digest is repinned.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): give the create family its mount step back

The create adapter mounted inside its first action so the create would run
ahead of the flush that made React pay its one lazy `Math.random()` draw.
#21088 pays that draw in the scheduler before it installs the seed, so the
position of the mount no longer decides which seeded value `clientMutationId`
reads, and the family goes back to the shape every other one uses: a declared
`mount` step carrying the cells the hook reads as it renders — the worktree,
the active tab, the device token — and a `create` step carrying the launch
options it passes.

The display-mode family keeps mounting from its `mount` action, which is that
same declared shape and never was the workaround.

* test(mobile): re-record the corpus at main's pin 9add08bb59

Recorded at main's baseline in a detached-pin worktree with this branch's
recorder, adapters and manifest. Main's own recorder on that pin reproduces
main's 705 goldens byte-for-byte first, and this run reproduces the same 705
beside the 22 this branch adds, so the corpus is main's plus this family.

Every body moved against the branch's previous recording: main replaced the
`sent` request count with the shared write ordinal, which stamps every sender
call, payload and effect. Six goldens moved headers only, all of them
scenarios that send nothing and write nothing, so they had no entry to stamp.

Counts follow the corpus: 727 goldens, 888 tests. The corpus still carries no
`reply-salvage` effect — the 22 added goldens contribute no checked read at
all, since this family's readers are the unchecked ones the inventory lists.
