Jinwoo Hong 23207bfde2 feat(mobile): register the source-control and review page routes (OTA phase C, C4.4) (#21957)
* refactor(mobile): move the review route body onto a component and the handoff seam (OTA phase C, C4.4)

The review route file called `useMobileDiffReviewController` at its top level. A switch cannot
keep it there: hooks are unconditional, so the whole controller — its client subscriptions
included — would run behind the shell's page whenever the shell renders. As an element passed for
`fallback` it is created and not mounted, which is how the explorer switch already behaves.

`useRouter` becomes `useRouteHandoff` in the same move. It was the one raw expo-router router left
in the review closure (measured: the only other value import of one is the seam's own web sibling),
and inside the page the session screen `openSession` replaces to is native, so that target has to
be handed back to the app rather than posted into a document that does not render it.

The params are read in the component rather than handed down, so this is the route body and the
route file above it is free to become a switch.

`session-router-seam-census.test.ts` gains the module by name. Kept with `useRouter` the census
reds twice — `imports nothing from expo-router that can navigate` names
`MobileDiffReviewRouteScreen.tsx (useRouter)`, and the completeness case gains `useRouter` — which
is what forces the swap rather than leaving it to a reviewer.

* feat(mobile): switch the source-control and review routes to the shell, still unregistered (OTA phase C, C4.4)

Both take the files switch's shape: `firstParam`/`firstReviewParam` on every param, `shellScreenRoute`
as the one predicate, `MobileWebShellScreen` keyed on `shellScreenRouteKey`, the native screen built
as an element and passed for `fallback`. Both gain a `.web.tsx` sibling for `index.web.tsx`'s reason —
the native file reaches OrcaMobileWebShellView, whose module throws at import in a browser, and the
route manifest imports every route.

Inert on its own. A switched route renders the shell only once `MOBILE_WEB_PAGE_ROUTES` lists it,
which is the next commit; until then the flag is the only thing that changes and it is off.

Query params are omitted rather than sent empty, and the whole record is omitted when none was
named: `tab=` is a lens named nothing and lands on `changes` through a different branch than an
absent one, and the same holds for `name`, `origin`, `scope`, `file` and `area`.

`pr` and `history` are deliberately not switched. Both are `Redirect`s into `source-control`, and a
redirect inside the page would leave the session bound to a pathname the page has left; left native
they replace into this route and its switch mounts the shell.

Three censuses red without their rows, measured on this tree:
- `mobile-web-app-web-overrides.test.mjs` `lists exactly the .web.* files on disk` names the two new
  siblings; `states a reason for every override` reds on a placeholder under 20 characters.
- `mobile-web-shell-flag-census.test.ts` `reaches the switched routes through that hook and no
  others` reds without the two `SWITCHED_ROUTES` names.
- `shell-screen-route-census.test.ts` `walks the route tree and finds them` reds without the two
  switch names.

* feat(mobile): register the source-control and review page routes (OTA phase C, C4.4)

Two entries in `MOBILE_WEB_PAGE_ROUTES`, five grants each, with the reason for each grant read off
the screen that needs it. The two lists are equal on purpose: the hub's changed-file rows push
review and review replaces back, and a target declaring no more than its opener is a hop the
handoff keeps inside the document. Registering either alone would have put a native frame and a
second bridge session between a changed-file row and its diff.

`pageRouteGrants` is derived from this list, so the two rows are a consequence of the entries and
there is no second table to edit. `pr` and `history` stay native redirects and are never listed; the
derived target list at this tree is [files, files/preview, source-control, [p], accounts,
agent-history, review, session, tasks, web], with no `pr` or `history` row, because the census reads
call sites and both redirects name `source-control`.

Measured on this tree, not carried from the draft:
- The hop census goes 8 -> 16. The eight new rows are exactly `{/h/[hostId], agent-history,
  files/[worktreeId], files/preview} -> {source-control, review}`, each handed off for
  `native.clipboard.write` and the first four also for `externalLink`. `source-control <-> review`
  is absent in both directions, which a new case now asserts as grant-list equality rather than as
  the absence of a row — absent is also what an unregistered route looks like.
- The Back census now walks six trees and finds 8 controls, both rules printing empty. The two new
  ones are `MobileSourceControlHeader.tsx:46 role=button label=Back to session` and
  `MobileDiffReviewHeader.tsx:48 role=button label=Back`, which is what C4.3 bought. The
  `ARRIVING_SCREENS` describe it wrote for this moment is removed: with the rows in
  `PAGE_SERVED_SCREENS` its trees are covered and its cases were a second reading of the same thing.
- Both closures reach the haptics seam, so `haptics` is declared by measurement: the seam census
  derives the reaching set and its two cases pass with the routes in its `ROUTE_MODULES` map.

Without the two manifest entries these red on this tree: `pins every hop the handoff must take away
from the page`, `keeps the hub and review local to each other`, `declares only routes the bundle has
a module for`, `reaches the built manifest`, `covers every page route and finds a control in each`,
and both haptics-seam cases.

`build-mobile-web-app-bundle.test.mjs` is split rather than fenced. The two pinned entries put it at
607 non-comment lines against the 600 cap, and the declaration block is a different concern from how
the bundle is built — it grows once per registered domain while that file does not. It moves whole
into `mobile-web-page-routes.test.mjs`, named for the module it is written against, so the next route
to register does not have to choose between a lint fence and a split it did not ask for.

* test(mobile): render-check the two page routes, and make the oversized stage-all readable (OTA phase C, C4.4)

The render check mounts both routes in a real browser, asserts each paints its own screen rather
than the Unmatched route with no console error and no page fault, and asserts each fetches its own
chunk on a client-side navigation. It also reads the shipped `img-src 'self' data:` out of the
Kotlin source it is served with, pins the Swift twin beside it, and asserts neither route leaves the
origin or logs a policy violation while it paints.

The avatar skip itself (ruling 3) is `PRCommentCard`: on web it renders its existing empty-avatar
`View` rather than letting one `<Image>` per comment attempt a fetch the policy refuses. Its branch
is pinned by a component test, which reds on the platform check being removed. The render check's
off-origin case is honest about being the negative half only — no comment card renders there,
because the PR chain behind it is not scripted, and the file says so.

The `useAnimatedScrollHandler` risk is answered by the two static facts rather than by a probe, and
they are recorded as assertions: the hook is deliberately outside the four `MAPPER_HOOKS` because it
is an event handler, and its updater's only effect is a write to `scrollOffsetY`, which
`RightDrawer.tsx` assigns in two places and reads in none. A later read reds that case the moment it
is added.

The `oversized` stage-all refusal (ruling 2, made testable by ruling 5) was a silent no-op, and this
is the fix as well as the case. Measured on this tree before it: `git.bulkStage` with 12,000 paths
posts one 1,033,012-byte frame, the shell's reader drops it with `{ kind: 'refused', refusal:
'oversized' }`, and the page's promise never settles — `busyAction` never cleared and
`setActionError` was never called. Both new cases red by timing out at 15s against that path.

Refused at the page's own send boundary instead, under the shell reader's own predicate rather than
a second spelling of it: `isBridgeFrameWithinCap` is extracted from `parseBridgeMessage` and used by
both sides. `sendFrame` answers `sent` / `oversized` / `port-failed`, so `sendRequest` rejects with a
`BridgeRequestOversizedError` whose message is a sentence the panel puts on its error surface, and
the members whose contract is a boolean keep it. No delivery-unknown mark: the frame never left, so
nothing ran on the desktop and the smaller retry is safe to offer.

The case runs the real chain — bridge port pair, `useMobileGitRequests`, `runGitWorkflow` — with
only react-native and the haptics seam mocked, and asserts the message that lands is a sentence and
that the busy flag is raised and then cleared.

* test(mobile): drop the type assertions from the two new C4.4 test files (OTA phase C, C4.4)

The changed-code quality gate named five, all in the files the previous commit added, and a fence is
not the answer to any of them. A separate commit because a reported head does not move by amend.

- The comment fixture is a real `PRComment` rather than a cast: the type's six required fields are
  all this case needs, and the SAFETY disable that stood in for them was inert anyway — oxfmt had
  wrapped it onto three lines, and a wrapped `oxlint-disable-next-line` matches nothing.
- The image lookup goes through `findAll` on the host tag rather than `findAllByType`, which takes a
  component. Through `String`, because `node.type` is `ElementType` and React Native declares no
  intrinsic elements, so the compiler reads a bare tag comparison as unreachable.
- The runners hook takes its router from `useRouteHandoff` with expo-router mocked under it, which
  is how a `RouteHandoff` is obtained rather than asserted into existence. No target is pressed.
- The rejection and the diagnostic are read through narrowings instead of casts, which also drops
  an `expect.any` that only type-checked because of one.

* fix(mobile): keep a frame the page cannot serialize inside the send contract (OTA phase C, C4.4 round 1)

Round 1 finding 1. The oversized refusal moved `JSON.stringify` outside `sendFrame`'s `try`, so a
frame carrying a cycle, a `BigInt` or a throwing `toJSON` threw past the whole send path. Three
things followed, all measured here on a cyclic `params`:

- the caller was rejected with a bare `TypeError` from `JSON.stringify` instead of the
  `BridgeSendFailedError` every other undelivered frame raises;
- no `send-failed` diagnostic was raised, so nothing recorded that a frame had been lost;
- `sendRequest` opens the id before it posts and abandons it on the way out, and the throw skipped
  the abandon: 63 of the 64 in-flight slots were usable afterwards, against 64 on a client that sent
  no such frame. Sixty-four of them and every later request is refused with nothing to say why.

`posted()` carried the same escape into the members whose contract is a boolean, where a throw is
worse still: those callers are taps and teardowns with no catch on them.

Serialization goes back inside the `try`, with the oversized refusal kept in front of the post. The
docstring said the port arm's throw is never `JSON.stringify`'s, which was exactly the assumption
that broke; it now says why the call sits where it does.

The new file is the pin: the rejection's name, the diagnostic, nothing reaching the shell, and the
slot count with a no-cyclic-frame control beside it so the count cannot pass by the cap moving. Both
changed cases red on the serialization moving back out — `expected 'TypeError' to be
'BridgeSendFailedError'` and `expected 63 to be 64`.

* test(mobile): pin the page's frame cap to the reader's, at the boundary and by construction (OTA phase C, C4.4 round 1)

Round 1 finding 2. Nothing held the sender's predicate to the reader's. Replacing
`isBridgeFrameWithinCap(json)` with an inline `json.length > BRIDGE_MAX_MESSAGE_BYTES + 1` passed 85
of the 86 mobile-web-shell and source-control test files on this tree, and a frame at exactly cap+1
would then be posted and silently dropped — the hang the refusal exists to end, back for every frame
in that one-unit band.

Two rules, because either alone passes against the defect:

- The boundary. A frame of exactly the cap is posted, arrives at `parseBridgeMessage` and is
  accepted; a frame one byte over is refused with `BridgeRequestOversizedError`, posts nothing, and
  is the same string the reader answers `oversized` to. An off-by-one reds the second.
- The census. The client reaches the cap through the shared predicate and does not name
  `BRIDGE_MAX_MESSAGE_BYTES` at all, and the module that exports the predicate is the module that
  parses inbound frames. A private copy that is correct on the day it is written reds here.

The overhead the boundary frames are built from is itself checked rather than trusted: a frame asked
for at exactly the cap must serialize to exactly the cap, so the constant cannot rot behind an
envelope that grew a field.

Against the mutation both new rules red — `expected null to be 'BridgeRequestOversizedError'` and
the census failing to find the predicate — while the rest of the suite stays green, which is the
finding reproduced.

* fix(mobile): count the outbound frame in the unit both shells count it in (OTA phase C, C4.4 round 1)

Round 1 finding 3. Read off both shells rather than assumed, and they agree: iOS gates the inbound
frame on `json.utf8.count` (`MobileWebShellView.swift`, through
`MobileWebShellBridge.acceptsByteCount`) and Android on `json.toByteArray(Charsets.UTF_8).size`
(`MobileWebShellView.kt`, through `acceptsMobileWebShellBridgeByteCount`), both against `640 * 1024`.
UTF-8 bytes on each platform.

The predicate was already right. `isBridgeFrameWithinCap` decides on `utf8ByteLength`, and the
`raw.length` clause in front of it is a cheap refusal in the safe direction, not a second rule: every
code unit encodes to at least one byte, so a string over the cap in units is over it in bytes too.

The diagnostic was not. It reported `json.length` — UTF-16 code units — in a field named `bytes`, so
a frame of CJK text read as a quarter of the cap at the moment it was refused by it. It now reports
`utf8ByteLength(json)`, and the type says which unit that is.

Pinned with a 250,000-character frame of three-byte characters, which is under the cap in code units
and over it in bytes, plus a source case reading the measuring expression out of each shell. Three
mutations, all red: dropping the byte clause from the predicate reds the refusal (`expected null to
be 'BridgeRequestOversizedError'`) and the diagnostic; reporting `json.length` again reds the
diagnostic alone (`expected 250094 to be greater than 655360`), which is the defect this commit
fixes, in the number it would have printed.

* test(config): drop the render check's avatar assertion, which could not fail (OTA phase C, C4.4 round 1)

Round 1 finding 4. The case asserted that no avatar host was requested while both routes painted,
which reads as a proof of the web skip and is not one: no comment card renders on either page,
because the PR chain the file's own closing note names is not scripted. Reproduced here — deleting
the `Platform.OS !== 'web'` guard from `PRCommentCard` leaves the file at 5 passed.

Deleted rather than propped up. Giving the page a presence precondition means five hand-written
fixtures against five Zod schemas inside the shell double, which is exactly what the harness's
docstring says that double must not become. So the only proof of that branch is
`pr-comment-card-web-avatar.test.tsx`, which reds when the check is removed, and the render check now
says so in its header instead of implying otherwise.

What survives is a property of these two closures rather than of that component: not one request
leaves the origin while either route paints, and nothing either paints violates the policy. That one
can fail — planting a `fetch` to a provider host in a module both routes reach reds it twice, on the
console-error case and on the off-origin case, with the `connect-src 'self'` refusal in the output.

The CSP half is unchanged and was never in question: the served header is read from the Kotlin source
and the Swift twin is pinned beside it.

Jinwoo Hong e9b180685b feat(mobile): render Mermaid diagrams on the page from one deferred engine artifact (OTA phase C, C7.10 B) (#21871)
* test(mobile): measure mermaid rendered in the page

Red-first for C7.10 item B. The check mounts the real web sibling in
chromium and webkit under the shipped shell CSP and asks four things of
it: that a diagram renders with zero policy violations and zero eval /
new Function calls, that the SVG is the native buildHtml's own output
once the diagram id and xmlns:xlink are normalised away, that a hostile
diagram lands inert, and that a source change, an unmount and a remount
leave exactly one SVG and no listener of the first mount.

The equality oracle is buildHtml itself, bundled for Node behind a
Proxy stub for its native imports and served as its own document in the
same browser, so neither side of the comparison is retyped.

All eight cases fail on this commit: the sibling is still the labelled
source box.

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

* test(mobile): fence the session download rather than its module list

Ruling 28. mobileWebAppRouteClosure reads metafile.inputs, which holds
dynamically imported modules under splitting: true exactly as it does
under splitting: false, so it cannot say "on demand" about anything: an
on-demand mermaid moves the session route's module list 4320 -> 6362
while its download does not move at all.

So the fence moves to entryStaticClosure. The new helper walks the
emitted chunks from the output the route's own module landed in and
follows import-statement edges only, and hands back both halves, because
mermaid's absence from the download is only a measurement while its 66
files are present in the deferred half.

The module list's new total is recorded in the docstring with its reason
and asserted beside the engine's own file count, which moves only when
the pinned mermaid version does.

Red on this commit: no mermaid in the closure yet.

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

* feat(mobile): render mermaid in the page

The web sibling stops being a source box. mermaid is a browser library,
so the page imports it inside the render effect and draws the diagram in
this document: no WebView, no 3.7 MB engine string, and nothing of the
engine downloaded by a session with no diagram on it.

What replaces the sandbox is mermaid's own securityLevel: 'strict',
which runs its serialized SVG through DOMPurify. The native path's
</script> escaping has no analogue here and needs none, because the
source is a JS string argument rather than text spliced into an inline
script. Measured in both engines: a script in a label, a </script>, an
onerror and a javascript: click all land inert.

The configuration is now one object both hosts read, so the theme cannot
drift between the page and the phone; buildHtml serializes it instead of
holding a second copy. It gains suppressErrorRendering, because mermaid
otherwise draws its own error diagram into a temporary element and leaves
that element behind when it rethrows -- an orphan SVG on the page, and on
native a diagram the component is about to replace with the source box
anyway.

The dispose clears the host on unmount and on a source change; the id is
a useId, because mermaid writes it into the stylesheet inside the SVG and
it has to be a CSS identifier.

Also re-records the closure total the previous commit pinned: with the
real component the session route's module list is 6376, not the design
probe's 6362, and the reason is in that file's docstring.

* fix(mobile): budget the deferred engine's chunks apart from the routes

Putting mermaid on the page took the app bundle from 69 emitted scripts
to 172, and the asset budget failed: 215 assets against a ceiling of
115. The cause is not a page split running away, which is what that
ceiling is for -- it is that mermaid lazily imports each of its own
diagram types, so one import() lands 103 scripts no route count
predicts.

So the ceiling gains a second term, named and measured (172 scripts with
mermaid against 69 with it aliased to a stub, at 11.17.2), rather than
the route term being raised to cover it. A page split running away still
fails on the route term, and the failure still says which of the two
grew.

The consequence is worth reading twice: the derived ceiling has to stay
inside the 256 assets the shell will load, and with 42 images it now
crosses that at 24 routes instead of 50. The bundle is at 215 today with
14 routes, so there is room for about ten more routes before a green
build produces a manifest no phone will open.

Measured by the config/scripts suite failing on this head, not predicted.

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

* refactor(mobile): pre-bundle the page's mermaid into one artifact

import('mermaid') from inside the app bundle emitted 103 scripts, not
one: mermaid lazily imports each of its own diagram types and esbuild
splits along those boundaries. Every one of those scripts sits inside
the OTA generation the phone has already downloaded, so the split moved
no bytes over the wire and spent 103 of the 256 manifest assets the
shell will load -- which is the scarce resource here, and the reason the
previous commit had to invent a second ceiling term.

So a sibling generator bundles the package into one ESM module beside
the WebView engine it already builds, emitted by the same postinstall
run, gitignored and lint-ignored with the others. The page imports that
artifact on demand instead, through a loader whose return type names the
two calls the component makes -- checked against the artifact's own
inferred export rather than cast to it.

Measured, at 14 routes:

  emitted scripts   172 -> 69   (68 with no deferred engine at all)
  manifest assets   215 -> 112  (111 with none)
  session modules  6376 -> 4323 (+3 over main: config, loader, artifact)
  chunks fetched for one graph TD   27 -> 1
  bytes fetched      837,530 -> 3,482,965

The static-closure fence is unchanged in meaning and now reads on the
artifact: absent from every chunk the route reaches by an import
statement, present in the deferred half. The rendered SVG is byte-for-
byte what it was, so the equality against the native document still
holds on both engines.

Also adds the diagram to the webview-consumers list, which is what that
list means: its native component imports the package and its sibling is
what the builder resolves instead.

* revert(mobile): drop the deferred-engine ceiling term, keep the control

With the engine pre-bundled into one artifact the bundle emits 69 scripts
at 14 routes against the route term's 72, so the second term this series
added has nothing left to do and the route count is the only term again.
mobileWebAppBundleMaxChunks and the asset ceiling derived from it are
back to what main has; the shell's 256 assets are crossed at 50 routes
again rather than at 24.

What stays is why. A ceiling raised to admit 172 scripts would have
admitted any split at all, so the budget test gains the control that
holds the line: the single-artifact count passes the ceiling and the
lazily-chunked count fails it, both measured at 14 routes, with mermaid
named as what produced the second.

Red before the term came out: the control failed asserting 172 > 175.

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

* test(mobile): keep build output out of the raw-request-port census

The census walks mobile/src for AST reaches into the unvalidated request
port, and the pre-bundled mermaid artifact is the first generated file
under src that is executable code rather than a string literal. Two of
its own vendored dependencies contain the token `sendRequest`, so the
walk read minified third-party code as a new call site and asked for an
inventory line nobody can ever migrate.

So `*.generated.ts` joins node_modules and test files in that file's
stated list of what it does not scan, with the reason. The scripts that
emit those artifacts are ordinary source and are still scanned, which is
where a real reach would be.

Two halves to the new control, because a filter that skipped everything
would satisfy either alone: nothing generated is left in the scan, and
the matcher still finds the port when handed one line of code.

* fix(mobile): escape the shared config into the native inline script

buildHtml spliced JSON.stringify(MERMAID_DIAGRAM_CONFIG) straight into
the inline <script>, twenty lines below the function that exists because
JSON.stringify leaves `<`, `>`, `&` and the U+2028/9 separators raw. Inert
at today's five hex colours, and not inert for a themeCSS or a font stack,
which is free text going into the same script element.

So the escaping splits from the stringify and both callers use it: the
source keeps its own wrapper, the config gets one. Those characters only
ever appear inside JSON string literals, so escaping them is valid for an
object serialization exactly as it is for a string.

Red first: a config carrying `</script><script>` put four raw closers in
the document where a benign build has two.

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

* fix(mobile): pin the page mermaid type against the package's own

The loader returned the artifact's default as PageMermaid, which checked
that two names exist and nothing about their shapes: the artifact is
minified vendor output and both members infer as `any` there -- a probe
assigning engine.render to a number compiles -- and `any` satisfies every
signature there is.

So the shapes are asserted against the package's `Mermaid`, which is
precise. A PageMermaid member whose signature the engine does not really
have now fails at this line rather than at a call the page makes.

In the product module, not a test: mobile/tsconfig.json excludes test
files, so a type-only assertion in one is never compiled. Underscored
because it is a compile-time statement with no runtime reader, which is
the form the linter asks for.

Control, verified both ways: changing render to (id: number) => Promise<{
svg: number }> reds tsc naming both parameter and return, and the real
signatures compile.

* docs(mobile): re-measure the chunk series and say what it does not show

The four-point series was stale and read as a slope it is not. Measured
again on this head, by copying the route tree and dropping routes from
the end of the sorted key list -- both siblings of each, because deleting
a .web.tsx alone leaves the native file for the builder to resolve and
measures an entirely different closure, which is how the first attempt
at this produced 77 scripts for 14 routes:

  8 routes  -> 32 scripts
  10 routes -> 43
  12 routes -> 61
  14 routes -> 69   (the real tree)

Between four and nine more per route depending on which route, so 4r + 16
is a bound and not a fit, and the justification now says that instead of
claiming three per route. It also says the part that matters more: at 14
routes the tree measures 69 against 72, and the last two routes cost the
8 the ceiling grants for two. The fence is at break-even, and the new
assertion states that slope from the function rather than from a comment.

Also records what the generation weighs, since every chunk ships in it
whether or not a phone fetches one: 8,016,714 bytes across 112 assets
against the 9 MiB ceiling, 84.9%, 1,420,470 left. It was 4,539,090 before
item B, and the engine is the difference.

* test(mobile): pin the native fallback under suppressErrorRendering

The shared config reaches the phone too, and it gained a key the native
path did not have. So the native document is now loaded for a diagram
that throws, in both engines, with window.ReactNativeWebView standing in
for the host: mermaid's run still rethrows, the document's own catch
still posts `error`, and that is the message the component turns into the
source box.

Measured both ways, so the case says which half the key owns. Whether
the fallback fires does not depend on it -- `error` is posted with the
key and without it. What depends on it is that nothing is drawn behind
the fallback: removing the key leaves mermaid's own error diagram in the
document and reds this case at 1 SVG against 0, on chromium and webkit
alike.

not `error`, and one SVG.

* refactor(mobile): one walk for every source census, without build output

Nine censuses under mobile/src each held a copy of the same recursive
walk, and each decided for itself what a source file is: seven had no
opinion about generated files, one excluded them in its own regex, and
one had the exclusion I added last round. So all nine read 7.9 MB of
emitted vendor code -- 3.7 MB of mermaid for the WebView, 3.5 MB of it
for the page -- and the two largest censuses TypeScript-parsed all of it,
looking for call sites nobody wrote and nobody can move.

That is what took rpc-params-contract-type-only-boundary over its 5 s
timeout in CI once the fifth artifact arrived. Measured here, median of
3, import plus tests:

  main, 4 artifacts, no exclusion   1004 ms   (slowest case  831 ms)
  with the 5th, no exclusion        1513 ms   (slowest case 1358 ms)
  with the 5th, this commit          947 ms   (slowest case  788 ms)

So it lands below where main has it, not merely below where I left it.
Across the nine, four more halve: rpc-operation-cast-fence 769 -> 441,
rpc-subscription-boundary 946 -> 468, unchecked-rpc-reader-boundary
1042 -> 538, lifecycle-owner 747 -> 433, reanimated-web-mapper-deps
1028 -> 516. The two that already excluded generated files do not move.

What each census counts as interesting -- extensions, whether test files
are in -- stays its own, because they genuinely disagree. What counts as
a source file at all is now said once.

The control is the file that started it: a *.generated.ts whose text
holds exactly the import a census is hunting, planted beside an ordinary
file carrying the same text. The generated one is not returned and the
ordinary one is, so the absence is a measurement. A second control reads
mobile/.gitignore and holds the predicate to every artifact the tree
generates, and a third fences the walk itself to one spelling, so a tenth
census cannot paste the cost back in.

* docs(mobile): correct why the type pin sits in the product module

The comment said a type-only pin in a test file "is never compiled".
That is false: mobile/tsconfig.json excludes *.test.ts, but
tsconfig.test.json is a second program that does check them, run by
check:tests-typecheck and held by the tests-typecheck ratchet.

The conclusion is unchanged and the reason is now the true one. The app's
own typecheck is the unconditional gate and would not cover a pin written
in a test; the test program is real but carries a grandfathered baseline
and a few files held outside it on purpose. And the assertion is about
this module's own type either way, so it belongs beside it.

Comment only; tsc, the ratchet and both lints re-run on the file.

Jinwoo Hong c77a82f783 feat(mobile): fire the page's haptics over the bridge notify (OTA phase C, C7.10 E) (#21864)
* feat(mobile): give the page a haptics notify and the grant that gates it

`native.haptics.trigger` joins the envelope's notify union with a `kind` of exactly
the five `src/platform/haptics.ts` has, and the single token `haptics` joins
`BRIDGE_NOTIFY_GRANTS` and `MOBILE_WEB_SHELL_GRANTS`. A notify rather than a verb
because nothing is owed back: a reply would spend a slot in the same 64-deep
in-flight window a forwarded request does, and there are 90 call sites in this app,
some of them one per row of a scrolling list (rulings-ota-c7.md ruling 30).

The arm's fields live in their own module because `bridge-envelope.ts` is at its
line cap, as `bridge-event-envelope-bytes.ts` already is; the version literal stays
in the envelope, so the fields are spread in beside it rather than reading it back
through an import cycle.

The shell's half rides `onHaptic` on `BridgeHostOptions`, as every other
device-local notify does: the host is the protocol's side of the bridge and a static
import of the app's haptics would put `react-native` and `expo-haptics` in its
graph, which breaks every test that loads it. `page-haptics.ts` is the one mapping —
`haptics.ts`'s own functions, its `Platform.OS` split and its Android
`HapticFeedbackConstants` untouched.

The dispatch branch rides along with the union rather than waiting for the page
side: `Record<BridgeNotifyName, …>` and the `notify` fall-through are total over
that union, so the shell does not compile without it. That is the totality working,
and `bridge-notify-grants.test.ts` shows it as the TS2741 a missing row is.

Red first: the envelope cases per kind, the ungranted refusal, the grant-list pin
and the missing-row type error all failed against the tree before this. Control on
the dispatch: neutering `options.onHaptic` reds 2 of the 29 cases.

* feat(mobile): post the page's haptics over the notify instead of doing nothing

`haptics.web.ts` stops being five no-ops. Each of the five posts its own kind
through the notify seam the entry publishes — the same shape
`publishExternalLinkOpener` has, and for the same reason: every caller is a plain
function inside a row's press handler that no provider wraps. `notifyHaptics` joins
the page client beside the other gated notifies and answers whether the frame left,
which nothing reads: a tap that did not buzz is what the page did before this, and a
warning per refusal would be one per row of a scrolling list.

Measured off the frame the client posted rather than a written copy of its shape,
which is what drifts: 77 / 74 / 72 / 70 / 73 bytes for mediumImpact / selection /
success / error / edgeBump, the widest under 0.012% of `BRIDGE_MAX_MESSAGE_BYTES`,
and a twelve-row scroll 888 bytes across twelve frames.

The `web-overrides.json` reason now says what the file does instead of what it
declines to do.

Red first: the nine web-seam cases failed on `publishHapticsNotifier is not a
function`, and the six client cases on `notifyHaptics is not a function`.

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

* feat(mobile): grant haptics on every page route, with a census that derives the list

All five declared page routes carry the `haptics` grant, and the list is a
measurement rather than a hand choice: `WorktreeListRow` is in every page closure and
calls the seam, so a route without the grant is a page whose taps stop buzzing with
nothing on screen to say why. Grants are resolved once from the route the shell
opened and held for the session, so the declaration is the only place to fix it.

`mobile-web-app-haptics-seam.mjs` is the shared walk, beside the external-link one:
it reads the kinds off the tuple that declares them, finds every exported `trigger…`
function in a haptics module, and reports the kind each one posts. The posting call is
found through the binding `publishHapticsNotifier` assigns rather than a local spelled
`post`, because a rename would otherwise turn every posting site into a non-posting
one and leave this green on a page with no haptics at all.

The census proper holds each route's closure to the `.web.ts` sibling, asserts at
least one importer so the grant is not idle, and derives the granted-route list from
the closures. The control is the design's: the same walk over the native sibling
finds the same five functions and no posting site, so "all five post" is a number
rather than an empty scan.

Controls run: dropping `haptics` from one route reds 1 of 23; neutering one web post
reds 1 of 23.

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

* test(mobile): record what the haptics notify costs a page closure

One module. Every page closure grew by exactly `bridge-haptics-notify.ts`, and it
arrives through `page-route-policy.ts` reading the grant token rather than through the
seam, whose import of the kind type is erased; its only dependency is `zod`, which the
envelope already put in every closure, so the module total moved by the same one.
Local counts per route went 294 → 295, 379 → 380, 435 → 436, 309 → 310, 335 → 336.

Pinned structurally rather than as a total, because an absolute closure count is
main's to move and a number that drifts for unrelated reasons is one nobody reads.

The call sites this replaces, measured over product modules: `triggerError` 43,
`triggerSuccess` 24, `triggerSelection` 12, `triggerMediumImpact` 10,
`triggerEdgeBump` 1 — 90 across 35 importing modules, which is the design's count plus
`page-haptics.ts` itself.

* test(mobile): carry the haptics grant into the shell's two grant pins

`bridge-host-init.test.ts` names the grants `init` issues, so the token belongs in
that list. `MobileWebShellScreen.test.tsx` now mocks `expo-haptics` for the reason it
already mocks the clipboard and both pickers: the screen hands `playPageHaptic` over
and reaching the real module pulls in an Expo runtime this test does not have, which
failed the whole suite at import. Which expo member each kind reaches stays in
`page-haptics.test.ts`.

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

* refactor(mobile): map each haptic kind to a named import, not a namespace index

The changed-code gate refuses a computed reference into an imported namespace, in
both the mapping and its test, and it is right to: `haptics[NAME_BY_KIND[kind]]()`
is a call nothing can follow. Each function is a named import instead, which also
keeps the second compile-time direction — a row naming something `haptics.ts` does
not export is now an import error rather than a `keyof` mismatch.

The third direction moves with it, from a namespace read in the test to the census
that already reads both files' text: `hapticsImportedNames` names what the shell's
mapping takes from the app's haptics, and the census holds that to the five the
native file exports. So a haptic added there with no kind of its own still fails,
and now it fails where the other two siblings' names are already compared.

The test's two `as` assertions become one annotated hoisted type, the shape
`MobileWebShellScreen.test.tsx` uses.

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

* docs(mobile): state the true reason the haptics grant is one token

`GRANT_NAME_PATTERN` accepts `native.haptics.trigger` — it admits `native.<a>.<b>`
with lowercase segments, which is why it rejected `native.media.readChunk` and
rejects `navigate-back`, not a dotted name as such. So four comments claiming a route
declaring the notify's own name would have its bundle refused were false, and they
are gone: the grant is a token because the notify table's grants are tokens, a notify
not being a verb, and the dotted names in `MOBILE_WEB_SHELL_GRANTS` are spread from
the verb table alone.

Also folded, with the false claim: `implementedPageRoutes` filters on
`grants.every(implementsGrant)`, so a token every page route declares couples the
whole set to a shell that carries it — against one without it, no page route is
served at all and the phone renders five native screens. Stated in the function's
docstring and beside the census's derived list, and pinned: the same declaration
under a grant this build does not implement comes back empty, with the token-free
route as the control. Removing `BRIDGE_HAPTICS_GRANT` from `MOBILE_WEB_SHELL_GRANTS`
reds that case.

`%#` consumes no argument, so the web seam's five cases were titled with the whole
function body; the kind is the first element now and `%s` names it. One 110-char
comment line in `bridge-client-notifications.ts` wrapped to the file's 100; the two
still over it there are main's.

Jinwoo Hong e6aa90ff36 test(mobile): certify the browser pane's golden families and render it in a page (OTA phase C, C6.5) (#21777)
* test(mobile): pin the browser pane's golden families

The half pin for C6: 4 families, 15 goldens, every verdict the one C2's
rule predicts. Measured per family with vitest `-t` over the full
787-golden corpus, with C1's 103 reproduced golden-for-golden as the
control: 6 byte-identical, 9 result-absent-settlement.

No composed `c6-page-closure.ts`: a composed table is pinned against a
route and the browser is a pane, so C7's route is what composes this
with C1's.

The derivation census does not wait for that route. `mobileWebAppRoute-
Closure` becomes one case of `mobileWebAppModuleClosure`, which takes
any entries, so the pane's own closure can be read from the module. Two
cases: the pane alone reaches exactly the pinned four, and the pane
beside `app/h/_layout` adds exactly those four and no other, with the
layout reproducing C1's 22 as the control for the difference.

Closure at this base: 48 local modules alone, 34 beyond the layout, 30
under `src/browser` and four through the web siblings. The design said
23, all under `src/browser`; it was measured before C6.2 and C6.3 added
those siblings, so the pin carries the re-measured number.

`browser.screencast` has no golden at all, so this certifies the input
path and says nothing about the frame path.

Red first: with `browser.wheel` dropped from the table, both census
cases fail naming the missing family; restored, the file's 10 cases pass
and the parity suite reports "15 goldens in 4 families, 6 byte-identical".

* test(mobile): pin the frame budget against the shell's real frame

Ruling 2's pin. `binaryEventEnvelopeBytes()` sizes the mobile view's
device scale from a skeleton it builds itself, and until now its only
check was another skeleton of the same shape in the same file: two
copies of one assumption agreeing with each other.

This measures the real thing. A frame with CDP's nine metadata fields
and a real `Page.screencastFrame` timestamp, encoded by C6.1's
`encodeBridgeScreencastFrame` and serialized by the real
`BridgeHostSubscriptions`, posted through the host harness: 303 bytes
besides the image, against a bound of 516.

Held above is not enough on its own — 213 bytes of slack is room for the
shell to grow the envelope by a field the page never hears about — so
the bound is reconstructed exactly instead. Every byte of that slack is
a number this frame prints narrower than a double can; adding those back
gives 516 on the nose.

The budget cases run a generated noise image at the budgeted scale, not
a committed fixture: the worst case is the image JPEG compresses least,
and a photograph sits a tenth of the way to it. 901,161 px at 0.545
bytes per pixel is 491,132 bytes, which the shell posts at 654,857 of
the 655,360-byte cap. One envelope more and the shell drops it, which is
ruling 1 read from the budget's side.

Red first, two ways. Drop the metadata widening from the bound and three
cases fail, the sharpest being the real shell answering the frame the
page thought it could send with zero posts. Add a field to the shell's
own envelope and the reconstruction fails at 516 against 548, where the
existing suite stays green on all 14 — which is the drift this file
exists for.

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

* docs(mobile): record the measured frame bytes, correcting e7cd24ef10

The previous commit message says the shell posts 654,857 bytes for a
frame at the budgeted area. That number was not measured; I wrote it
from the budget arithmetic instead of reading it off the harness. The
measured value is 655,147, which is 213 under the cap rather than 503.

Nothing in the assertions changes — they compare against the cap and
the bound, never against a literal — but the figure now lives in the
file where it was measured rather than only in a message that has it
wrong.

* test(mobile): render the browser pane in a page and paint a real frame

The only place C6's whole frame path runs. Every other check reads one
half: the shell suites drive the host with no page, the page suites
drive the hooks with no shell, and the parity pin certifies the input
path from a recording.

Ruling 4: no route is added. `bundleMobileWebApp` already takes an
`appDir`, so this builds a one-route tree of its own and nothing under
`mobile/app` moves. The shell double grows a screencast lane to serve
it: it accepts a subscribe, posts `event.binary`, and prices each frame
the way `BridgeHostSubscriptions` does, so an over-cap frame is dropped
where the page can watch the stream survive it.

Six cases: the pane subscribes with `wantsBinary` and paints the frame
it is handed; a second frame flips the double buffer; an over-cap frame
is dropped and the next one paints on the same subscription; the grant
withheld produces the update-the-app copy and no subscribe at all; a tap
issues one `browser.mouseClick` at the centre of the source viewport;
and no request leaves the bundle's own origin.

Measured. The frame the pane asks this viewport for is 390x698, which as
noise is 201,924 base64 characters. The phone's mobile-mode frame is
780x1424 and encodes to 811,168, which is 124% of the cap and the reason
the area budget exists; the over-cap case uses 2400x2160 at 3,761,580,
574% of it. The tap maps to (194, 356) against a 390x712 source, one
device pixel off centre because the rendered width is 382.33 CSS pixels
for 390 source pixels.

One finding, recorded rather than fixed because it is not the pane's.
The page files a CSP `script-src` violation on every load, on any route:
Zod 4 feature-detects its compiled path with `new Function('')`, the
shell's `script-src 'self'` blocks it, Zod catches the throw and takes
the interpreted path. The page is correct and the report is filed
anyway. One case names it so a second `eval` is visible, and every other
case asserts no violation beyond it.

Red first, twice, both by reverting behaviour C6.2 landed. Stub out the
decode probe in `whenBrowserFrameDisplayable` and the flip case fails on
two identical frame digests. Point `updateBrowserImageSource` at the
host element instead of the surface child and the paint and flip cases
both fail. The first case's comment is corrected by the first of those:
it claimed a visible layer proved the decode-then-flip, and the frame
still paints with the probe gone, so the flip case is what proves it.

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

* fix(mobile): sweep the worst-case JPEG cost instead of taking one point

The reviewer is right, and it is worse than the report says. At 0.545
bytes per pixel, 90 of 143 viewports posted a frame over the cap, and
59 of the 111 the budget claims to fit were dropped outright by the
real shell — 390x712 at scale 1.8 among them.

The old number came from one 2400x2160 frame. A single large frame is
the cheapest per pixel in the whole range, so a worst case measured
there is not a worst case anywhere else.

Swept 143 viewports, widths 320 to 1400 and heights 480 to 1600, each
encoded by Chromium at the scale the real budget picks for it. Across
the 111 the budget fits, the cost ranges 0.54470 to 0.55351 bytes per
pixel. The constant is now 0.56: that maximum plus 0.00649, about 1.2%,
for the encoder version it was not swept on. The docstring carries the
sweep, the range, the margin and the date.

0.56 is a fixed point, not a guess. Raising the constant shrinks the
budget, which lowers the scale, which moves the cost; 0.555, 0.56 and
0.565 all leave the same 31 viewports over the cap, and every one of
those sits at the scale floor of 1, where the module already declines
to go blurrier and C6 ruling 1's drop rule is the protection. The new
test asserts both halves: nothing the budget fits goes over, and the
largest viewport it cannot fit is dropped by the real shell.

The sweep lives in `config/scripts` because it needs Chromium: the
frames are CDP screencast frames, so Chromium's encoder is the oracle
and a Node JPEG library would calibrate against the wrong bytes. It
drives the real budget, the real scale function and the real
`BridgeHostSubscriptions`, and runs in about 4 seconds.

Ruling 2's block in `browser-screencast-budget-at-the-shell.test.ts`
now says plainly what it measures. It feeds `noise(area * theConstant)`,
a byte count the constant itself produced, so it can falsify the
expansion and the drop rule but never the constant. It read as if it
validated the worst case, and it did not.

Red first: put 0.545 back and the sweep fails with 59 viewports, each
naming its scale and reporting `null` — the real shell dropping the
frame rather than posting it over the cap.

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

* fix(mobile): turn Zod's JIT probe off for the page, before any module

The page filed a CSP `script-src` violation on every load: Zod decides
whether it may compile by constructing `new Function('')` and reading
the throw as "no JIT here", the shell's `script-src 'self'` is exactly
that throw, and the browser reports it before Zod catches it. Zod's own
source gates the probe on `jitless` for this case.

`z.config({ jitless: true })` at the entry does not work, and the
reviewer's suggestion of putting it there was measured losing the race.
`$ZodObject` reads `allowsEval` when a schema is constructed, not when
one is parsed, so the first module-scope `z.object(...)` in the bundle
fires the probe — and esbuild evaluates the chunk holding zod and its
callers before the chunk holding any module of ours that imports zod. A
Function-constructor trap in the page put the call under `new ZodObject`
ahead of the entry's first statement.

`globalConfig` is `globalThis.__zod_globalConfig`, which zod adopts with
`??=` rather than replacing, so the banner can set the flag before any
module runs. That is where it now lives, beside the `process` shim and
under the same `MOBILE_WEB_APP_SHIMS` contract, which asserts it is
applied. Nothing is lost: the compiled path was never reachable in a
page under this policy.

The render check's `newCsp()` filter is gone. It dropped violations by
`blockedURI === 'eval'`, which would have hidden a real one, and every
case now asserts zero. The first case walks load and first paint, which
is where the second of the two reports fired. The dead `violations`
array is deleted.

Red first: blank the banner constant and four of the six cases fail,
each naming a `blockedUri: 'eval'` the filter used to swallow.

Finding, not fixed here and reported instead: the page bundles two
copies of zod, mobile's 4.4.3 and the repo root's 4.5.4, because
`src/shared/zod-salvage.ts` resolves upward. That is 808 KB of duplicate
source. Aliasing `zod` to one copy in the builder fixes it and was
measured working, but it changes which zod shared code runs in the
shipped page, which is a call to make on its own rather than inside a
CSP fix.

* test(mobile): give the shell double the whole canCarry rule and the acks

The double reproduced one arm of `BridgeHostSubscriptions.canCarry`, the
message cap, and silently carried anything the other two would have
refused: a window already holding its maximum frames, and a window whose
bytes the frame would push past the limit. It also ignored the page's
`ack` frames, so its window never reopened — which was invisible only
because no case streamed far enough to close it.

Both arms are in now, and the `ack` arm consumes the page's acks exactly
as the host does. The three caps are read out of `bridge-caps.ts` and
`bridge-host-subscriptions.ts` rather than retyped, the same way the
harness already reads the protocol version and the CSP, so a double
carrying a stale number is not possible. The render check's own
`640 * 1024` is gone with them.

One case for it: thirty frames of about 200 KB, roughly 6 MB through a
4 MiB window, nothing over the message cap, so a drop can only come from
the window. Every frame posts, nothing is dropped, and the page's ack
seqs are read back to show the window stayed open because the page acked
rather than because the double was generous.

The file docstring said the double answers no RPC. It serves a
screencast stream now, so it says that instead, and says what it still
is not: it decides no domain behaviour.

The dead `violations` array is gone, folded with the CSP commit.

Red first: make the `ack` arm inert, as it was before this commit, and
the case fails with `Set{'posted','dropped'}` against `Set{'posted'}`.
A first attempt at that mutation left the byte subtraction in place and
stayed green, which is the mutation being wrong rather than the case.

* ci(mobile): run the whole mobile-web-app family, not a list that goes stale

The `mobile_web_app` job hand-listed ten files. The render check this
chain added was not among them, so it would have skipped in CI — and it
was not the first: three landed censuses were already unlisted, and
their closure blocks only run with `ORCA_MOBILE_WEB_APP_DEPS_REQUIRED=1`,
so they are green in the sharded `test` job whether or not they ever
ran here. Nobody could see it.

The list is now two vitest filename filters, `config/scripts/mobile-web-
app-` and the one builder test outside that prefix. Quoted, because
vitest matches a positional as a substring against the discovered files
rather than expanding a glob: `mobile-web-app-*.test.mjs` finds nothing,
and it fails by reporting no test files rather than by running fewer.
Both forms were tried before this one was written.

It runs 18 files and 205 cases, against 10 files before. With mobile
dependencies absent, 111 of those 205 skip, which is the measure of what
only this job runs. Per file, cases CI has never run:

  browser-pane-render            7 of 7   (this chain)
  source-control-external-links  9 of 9
  source-control-keyboard        6 of 6
  source-control-text-inputs     6 of 19  (C4.2)
  frame-budget-sweep             4 of 4   (this chain)
  route-manifest                 2 of 17

Two more files the filter adds run fully in the sharded job already and
change nothing here: `browser-pane-text-inputs` (C6.4 — it censuses a
hand-written closure and never bundles, so unlike the report it was not
skipping) and `external-link-seam`.

The sweep is renamed into the family for the same reason. As
`mobile-browser-frame-budget-sweep.test.ts` it matched neither the job's
filter nor `pr-code-change-scope.mjs`'s `config/scripts/mobile-web-app-`
prefix, so a change to it alone would not have run the job that runs it.
It is also gated on the dependency check now: it needs no
react-native-web, but it launches Chromium, and that flag is what tells
the job with a browser from the one without. Unguarded it would have
failed the sharded `test` job outright.

That filter is a prefix match. `config/scripts/mobile-web-app-` and
`mobile/src/` both fire this job, and `.github/workflows/pr.yml` is in
GLOBAL_FORCE_PREFIXES, so this commit runs everything.

Also: `postedFrame` in the ruling-2 pin and in the sweep both reached
the binary lane through `?.`, so a subscribe that opened no stream read
as zero posts — indistinguishable from a dropped frame, which is the
verdict both files are about. They throw now. The render check's
restated `640 * 1024` went with the window caps in c73b405f81; the cap
is read from `bridge-caps.ts`.

* ci(mobile): record what the mobile-web-app job costs to run

The filter that replaced the hand list runs 18 files where the list ran
10, so the step's cost is now a function of what anyone names into the
family rather than of what a reviewer remembered to add. Measured on
this machine: 25-30s wall for the whole step, of which the frame-budget
sweep is 2.5s.

The sweep is the one part whose cost is a choice. It encodes 111 noise
JPEGs in Chromium, one per viewport the budget fits, so adding rows to
that set is a decision about this job's runtime and the comment says so
where someone would make it.

Found, not fixed, and reported for its own PR rather than folded here:
the page bundles two copies of zod, mobile's 4.4.3 and the repo root's
4.5.4, reached through `src/shared/zod-salvage.ts`, which resolves
upward while `mobile/src/` resolves to mobile's. That is 808 KB of
duplicate source and two module instances in the shipped page. Aliasing
`zod` in `mobileWebAppBuildOptions` fixes it and was measured working
during this chain; it is reverted and stays reverted, because it changes
which zod shared code runs in the page and that is not a call to make
inside a CI commit. The CSP fix in 71254ab3a9 does not depend on it:
`globalConfig` lives on `globalThis`, so the banner covers both copies.

* fix(mobile): load the frame-budget sweep's mobile modules after the dependency guard

vite transforms every file under mobile/ against mobile/tsconfig.json, which extends
expo/tsconfig.base.json; the sharded test job installs no mobile dependencies, so the
sweep's static imports failed the file at load before describe.skip ran. Type-only imports
stay static; the values load in beforeAll behind mobileWebAppDependenciesPresent().

* test(mobile): certify the frame budget at the quality the pane ships

Round 2: the sweep and the render check encoded fixtures at a retyped 0.72; both now read
BROWSER_FRAME_QUALITY (the sweep from the module, the render check through the harness reader),
so a quality change fails the certification instead of leaving it green. Every render case now
asserts zero CSP violations; the sweep pins the 32 viewports left at scale 1; three references to
a renamed file and a file that never existed are corrected; a shim count comment is made
count-agnostic.

docstring as the sweep's record.

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.

* 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.

* 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.

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

* 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.

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

* 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 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.

* 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.

* 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.

* 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.

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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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 edd9e3125b fix(mobile): give the page its height and its long press; C1.7 device proof (OTA phase C, C1.9) (#21589)
* fix(mobile): give the Route A document the height its mounted tree measures against (OTA phase C, C1.9)

The document this builder emits carries no stylesheet, so `html`, `body` and `#root` have no
height, and every box react-native-web lays out below the mount is `flex: 1` against a parent
that measures 0. The collapse is silent in every check that existed: the entry stamps `mounted`,
the route tree commits, `innerText` holds every row, and the accessibility tree reports each one
at the offset it would have had. Nothing is painted below the header, and nothing takes a tap —
the list sits inside a scroller the collapse clipped, and a phone reads it to VoiceOver while no
row responds. Lane C1.7 found it on both an iPhone 17 Pro simulator and a Pixel 9 Pro emulator,
and the same bytes reproduce it in headless Chromium.

The fix is the reset Expo's own web template ships for a react-native-web root, emitted inline
because the shell's CSP already allows `style-src 'unsafe-inline'` for the sheet react-native-web
injects at runtime; a linked asset would paint the collapsed layout until it landed.

The render check gains the assertion that would have caught it: the root's box measured against
the viewport, and the one control this route paints with no RPC answered — the New Workspace
button, positioned against the bottom of the root, which the collapse moved to y = -72 — asked
for by `elementFromPoint` at its own centre. Laid out is not reachable, so the check is a hit
test and not another read of the DOM. Without the reset it fails `expected +0 to be 844`.

* fix(mobile): let the page have the long press WebKit was taking (OTA phase C, C1.9)

The shell's WKWebView is built with the default text interaction, so WebKit installs its selection
assistant over the page. A hold on a worktree row raises the selection loupe over the row's own
text and the touch is cancelled before the page's responder sees it, which leaves every
long-press action in the page dead on iOS while a tap works. Lane C1.7 measured it: the same
injected hold opens the row action sheet on the native list and on the page in the Android
WebView, and does nothing in the page on iOS.

It is not the document's to fix, which the device disproved one rule at a time:
`-webkit-touch-callout: none`, `-webkit-user-select: none`, and both together all left the loupe
and left the hold undelivered, and headless Chromium confirms the property computes to `none` on
the page's text, so the CSS reaches it and WebKit's own gesture wins anyway.

The cost is real and named here rather than discovered later: the page has no text selection on
iOS, so selectable `Text` — markdown, diff rows, file preview, chat — cannot be selected there
until a page-side copy affordance exists. Everything the shell already forbids is unchanged, and
Android is untouched.

No unit test: the module's Swift checks compile the seven WebKit-free logic files and never import
WebKit, so a `WKWebViewConfiguration` cannot be built in them. The device proof stands in.

* fix(mobile): make the root reset the template's bytes, not a copy with an addition

The comment said the reset is what Expo's web template ships, and `margin:0` was not in it.
`@expo/cli@55.0.36/static/template/index.html` carries height, `overflow` and the root's flex box
and nothing else, and react-native-web emits `body{margin:0}` in the sheet it injects at runtime,
so the addition only covered the frames before that sheet landed. Nothing pinned it either:
removing it left all 60 tests green, which is the other way of saying it was never load-bearing.

Dropping it makes the string one thing with one source instead of a copy to keep in step with two.
The pins on the rest of the reset are unchanged, and so is the frame that mattered: the root still
has a definite height before the first paint, which is what the collapse needed.

* style(mobile): format the render check with the root formatter

`config/scripts` is formatted by the root oxfmt, not mobile's, and CI checks neither, so a 102-char
line I added sat over the root's `printWidth: 100` with nothing to catch it. Reflowed by
`./node_modules/.bin/oxfmt --write` from the repo root; no behaviour change.

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

* docs(mobile): say what the root reset shares with Expo's template, not that it is its bytes

"The bytes Expo's web template ships" is false and checkable: the template's own block is
pretty-printed with comments and trailing semicolons at 410 bytes, and this string is 112. What is
actually true, and what the next reader needs, is that it carries the same declaration set and the
same `id="expo-reset"`, minified.

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

* test(mobile): pin every rule of the root reset, not two substrings of itself

The check read the constant back against itself: `toContain(MOBILE_WEB_APP_ROOT_RESET)` plus two
substrings taken off that same constant. A rule dropped from it took the assertion with it, so
`body{overflow:hidden}`, `flex:1` and the `expo-reset` id were unpinned — and the render check
stays green without the overflow rule, so nothing else held them either.

Each rule is now a literal written here, named one at a time so a failure says which one went, and
the id is pinned beside them. Verified red-first: removing the overflow rule, the `flex:1`, or the
id each fails this test and only this test.

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.

* 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.

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.

* 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.

* test(mobile): state the two test fixtures' types instead of asserting them

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.

`const x: unknown = …` followed by `x as T` is the widen-then-assert the anti-slop gate

belongs at the literal, with its rationale on the line above it.

A remount cleared `pageReady` but left the flow alone, so the wait the retired

A refused `notify` fell through to the line about a view outliving its host,

bury one reaching past what it was told.

* fix(mobile): say what was wrong with the screen a refused shell named

C1.1's per-kind log lands on a branch that also refuses a route, and that
diagnostic was still falling through to the line about a view outliving its

* 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.

* 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 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,

* 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

`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

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.

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

* 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
ready workspace to `document-load-failed`, and deleted the generation on the way.

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

* fix(mobile): say which page notification the bridge refused and why

A refused `notify` fell through to the line about a view outliving its host,
which is a different fault and names neither the notification nor the reason.
The two refusals now get a line each, so a page that was told nothing cannot
bury one reaching past what it was told.

Jinwoo Hong 209d2d8df6 build(mobile): split the Route A page into per-route chunks (OTA phase C, C1.5) (#21475)
* build(mobile): split the Route A page into per-route chunks (OTA phase C, C1.5)

The page bundled as one 8.16 MB script because every route was a static
import. The route manifest now defers each screen behind `import()`, the
build is esm with splitting on, and the document loads the entry as a
module. What the browser parses before the first route can paint drops
from 8.16 MB to 908 KiB; the whole page still weighs the same.

Two budgets hold it: the chunk count, which catches a split running away,
and the bytes the entry reaches by static import, which catches it
collapsing back. The second is the one that matters, and it is measured
from esbuild's metafile because only that says which import is static.

The RequireContext stays synchronous, since expo-router reads keys() to
build the route tree before anything renders. A lazy module cannot answer
`unstable_settings` or `ErrorBoundary`, which expo-router reads off the
namespace, so a test holds that no route in the subtree exports either.

The render check now waits for the route's own text: the entry's mount
signal lands while the route chunk is still being fetched.

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

* fix(mobile): read a route's synchronous exports from esbuild, not a regex

`export { x as ErrorBoundary }`, `export class ErrorBoundary` and a re-export all
reach the namespace without matching the declaration pattern the guard was

A star re-export is now reported rather than read as clean.

* docs(mobile): say that the entry budget is not a per-route opt-out

expo-router reads a synchronous export from.

64 was three routes of headroom over the 53 chunks 14 routes measure, so C2's

budget.

* test(mobile): split the route-manifest tests out of the bundle builder's

The builder's test file passed 600 lines. The route manifest, the synthesized
RequireContext and the web entry are their own subject and move together.

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

* fix(mobile): give the export guard the builder's route-source loaders

Without .js as jsx the guard reported a React Native .js route carrying JSX as
"JSX syntax extension is not enabled" instead of reading its exports.

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

* test(mobile): assert the navigation fetches the tasks route's own chunk

"some new script arrived" passed on any fetch. The builder now names the chunk
each route lands in, read off the metafile, and the check asserts that exact
path arrived and was not already loaded.

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

* fix(mobile): resolve a route's realpath before matching it to its chunk

esbuild writes metafile input keys after resolving symlinks, so every scratch
route tree under /var on macOS reached no output and failed the build.

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

* fix(mobile): fail the build when the asset ceiling outgrows the shell's map

The derived ceiling had no upper bound, and the native shells return null for a
manifest over their own 256 rather than truncating it. At 42 images the formula
crosses that at 50 routes, inside what Phase C adds, so the build would stay
green while the phone got nothing. The number is read from the contract through
esbuild, not restated here.

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

* test(mobile): cover the two hard stops in the content-addressed naming

Both throws only ran through a whole bundle before, where neither can be
provoked. A cycle and a route no output claims are now asserted directly; each
test goes red when its throw is removed.

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

* fix(mobile): exit the app-bundle build on one line, not a stack

The route-export guard fails this script by design, and a raw stack put the
route and the export name under twelve frames of node internals. Mirrors the
verifier's exit; the message is printed as thrown because every throw on this
path already names its source.

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.

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

* style(build): satisfy the index-check lint rule in the CSP parser

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

* 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

* style(build): merge the duplicate node:fs/promises import in the census

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.

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

* chore(mobile): list the page transport in the raw request port inventory

The placeholder client implements the port, so the boundary test counts it as
an unlisted file. It belongs under OWNERS until C0.4's BridgeRpcClient
replaces it.
