Jinwoo Hong a134d1259e feat(mobile): tell users when a newer app binary is installable (#23755)
* feat(mobile): tell users when a newer app binary is installable

With OTA page updates, store releases get rare and users stop looking.
The shell now asks the channel that installed it. Android sideload
reads GitHub's mobile-android-v* tag refs and proves the release has
an APK. iOS reads the App Store lookup. A home card above Desktops,
dismissible per version, and Settings rows surface the result. The
check runs on the desktop updater's cadence: cold start, foreground
once 24 h have passed, and a 1 h retry after a failure.

The releases atom feed was not used because it lists only the 10
newest releases, which are all desktop builds, so it never carries a
mobile tag.

* refactor(mobile): parse update replies with zod schemas

The anti-slop gate refuses Reflect.get on dynamic input. The GitHub
refs, the release, the App Store lookup and the stored update record
are now parsed into named schemas before they are read.

* docs(mobile): say why the Android update source reads tag refs

Record why the Android source reads tag refs. The releases atom feed
and /releases?per_page=100 are both newest-first windows that desktop
releases fill. Either would silently report "current" once a run of
desktop builds pushes the newest mobile release out.

* refactor(mobile): load update state once and apply review rulings

Every check and dismissal now awaits one shared store load. This
replaces the merge that guessed whether a check had landed during the
load. A manual check that fails while the store loads therefore keeps
its 1 h retry instead of re-checking at once.

- checking is derived from the in-flight check.
- start() uses a per-start flag, so a StrictMode double start applies
  one load.
- A check that finishes after stop() writes nothing.
- A corrupt stored update record loses only itself.
- Tag refs are parsed with a single schema.
- The runtime wiring is folded into one file, and the card moves to
  home/.
- The recorded App Store fixture is oxfmt-formatted, with the same
  parsed value.

* fix(mobile): keep the update timer armed across a stop and restart

A check that stayed in flight across stop and restart returned
'failed' without rescheduling. The restart skipped arming because a
check was in flight, which left a live checker with no timer until
the next foreground. The stop counter is removed. schedule() already
arms nothing while no start is active, and saving a real result after
a stop is harmless.

* refactor(mobile): trim the update checker and Settings rows

- The load sets prefs and the due time only. start() re-arms the
  schedule after it.
- The Settings result hides through one effect keyed on the result.
- onUpdate receives the URL.
- The version row is bound once.
- The retry and timeout constants are no longer exported.
- The unused AppUpdateChecker type is deleted.

* fix(mobile): run the update check when its timer fires

The armed timer is the due time. Re-checking the wall clock when the
timer fired meant a clock stepped back skipped the check and re-armed
nothing. The due-time guard now applies only on foreground.

The binary version still comes from expoConfig.version. SDK 55
removed Constants.nativeAppVersion, so the no-expo-updates invariant
is now named in the comment.

* fix(mobile): recover from a future check time and use Apple's page URL

If the device clock was ahead when a check ran and was corrected
later, the stored check time is in the future. Cold starts then armed
a timer for the whole skew, and foreground never came due. The stored
state now reads as never checked in that case.

The iOS link is the lookup's trackViewUrl instead of a URL built from
trackId.

Jinwoo Hong da1c322b00 feat(mobile): one build-time switch picks native or OTA, default native (OTA phase E1) (#22193)
* feat(mobile): one build-time constant decides native or OTA, default native

EXPO_PUBLIC_MOBILE_SHELL is read in exactly one place, mobileShellBuildKind in
preferences.ts. Expo's babel preset inlines a literal process.env member
expression at build time, so a release bundle carries the answer as a constant
and anything but the exact string 'ota' — unset, empty, a typo — is native.
Every default build is therefore the native app, unchanged.

mobileWebShellFlagCanBeOn now answers __DEV__ or an OTA build, so the ability to
mount the page comes from the build and never from storage: a native binary
installed over an OTA one, same bundle id and same data container, still refuses
a stored 'true' without reading the key. An unset key reads on only in an OTA
build; a development build keeps its opt-in, and a stored 'false' wins
everywhere so the Troubleshoot toggle can switch an OTA build back to native.

That toggle now mounts wherever the flag can be on, which is the only way back
to the native screens in an OTA build, and its label names the build kind rather
than saying "(dev)". The bundle probe row beside it stays development-only: it
fetches.

The flag census gains two rules — one module reads the switch, in the member
form Expo inlines and not the bracket form, and one named function answers the
build kind — and the build-kind fence now lists the Troubleshoot route that asks
it. Docblocks that said a store build can never mount the shell now say it
mounts only when built for OTA.

* ci(mobile): one workflow input picks the shell, and no input means native

Both release workflows gain a `shell` workflow_dispatch choice, options native
and ota, default native, and hand it to the step that bundles the JavaScript as
EXPO_PUBLIC_MOBILE_SHELL. That is the Gradle assembleRelease step on Android and
the fastlane build_and_upload step on iOS; nothing else in either file sets it.

A tag push and a schedule carry no inputs at all, so `inputs.shell || 'native'`
yields native for them — the first OTA release is a dispatch with one field
changed, and every other run is the app we ship today.

Each build step prints the value it is about to build with, read back from the
same variable rather than from a second copy of the expression, so a run's log
cannot claim a shell the build did not use.

The new contract test evaluates that expression rather than matching its text:
absent, empty and 'native' all resolve to native, 'ota' to ota, and any
expression shape it cannot evaluate is a failure rather than a pass.

* build: the desktop packages the real page, and the placeholder is retired

build:mobile-web now runs the app builder and app verifier, and both take their
output root from MOBILE_WEB_BUNDLE_DIR in the packaging guard rather than each
carrying a constant of their own — one definition of where the bundle lives, so
a drift cannot leave electron-builder's beforePack looking at an empty directory
while the builder reports a tree it wrote elsewhere. build:mobile-web:app is
gone; it was the same two commands.

src/mobile-web/ and its two scripts go with it. What the app builder shared with
them is split into three modules named for what they hold rather than for the
bundle that used to own them: mobile-web-bundle-manifest.mjs (content types, the
canonical asset serialization, buildId, hashed assets, the protocol window and
the manifest write), script-entry-detection.mjs (isDirectInvocation, whose two
failure modes are Windows paths and symlinked entries), and
mobile-web-source-line-endings.mjs (the CRLF guard, now with a required
directory rather than a default pointing at the deleted tree).

The two suites that only needed *a* valid tree on disk — the beforePack guard
and the packaged-bundle guard — build one from mobile-web-bundle-fixture-tree
instead of bundling the whole mobile graph. It goes through the same manifest
writer the page does, so a manifest shape change still reaches them.

Also retired: the placeholder's tsconfig project and its typecheck lane, its
knip entry, its electron-builder exclusion and .gitattributes pins, and the
app-bundle test that asserted the shims stayed out of a builder that no longer
exists. pr.yml's page job builds the same bundle the package job ships.

Inert for native phones: they never fetch it.

* style(config): one import of node:fs/promises in the entry-detection suite

The changed-code quality gate's focused plugins read the two as a duplicate
import; the readFile line was left over from the split.

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

* docs: the comments that still describe the retired placeholder bundle

The web entry said it was built by `build:mobile-web:app` into out/mobile-web-app
and shipped by nothing. That script, that directory and that fact are all gone:
it is built by `build:mobile-web` into the packaged bundle dir, and a phone
mounts it only when the binary was built with EXPO_PUBLIC_MOBILE_SHELL=ota.

Two Windows cache keys explained themselves by naming src/mobile-web and "the
two bundle builders"; config/** now covers the builder, the verifier and the
manifest writer, and the spike's key no longer waits on a Phase C flip that has
happened. The keys themselves are unchanged.

Three scratch directories in the app-bundle suites and one in the verifier still
spelled the retired output root. Renamed to mobile-web, which is what the build
writes; they are temp subdirectory names and nothing reads them.

Jinwoo Hong 6731f08c0b fix(mobile): hold every hybrid shell switch on a neutral state while the flag is unresolved (OTA phase C, ruling 33.7) (#22077)
* feat(mobile): give the hybrid shell switches a third answer for the unresolved flag

Every route switch read the flag as `enabled !== true`, which spends the
window before the read settles on the native screen. With the flag on
that window costs a full native mount — subscriptions opened, screen
painted — that the shell then tears down and replaces.

`shellSwitchDecision` answers `pending` there instead, and
`ShellSwitchPendingScreen` is what a switch paints while it waits: the
base background with nothing on it, lifted out of the `web` route where
this view already was rather than written again.

A route the shell could never open is still answered `native` with no
wait, because the flag cannot change that outcome and a neutral frame in
front of a decided one is the flash this removes.

No switch is wired to it yet.

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

* fix(mobile): hold every hybrid shell switch on the neutral state while the flag is null

All ten switches read the flag as `enabled !== true`, so the window
before the storage read settles was spent on the native renderer. With
the flag on that window costs a full native mount — the session screen
opens its terminal, chat and tab subscriptions — which the shell then
tears down and replaces, and the user sees the native screen flash
before the page.

Each now asks `useShellSwitchDecision` and paints
`ShellSwitchPendingScreen` while the answer is `pending`, so exactly one
renderer mounts and it mounts once. `tasks` and `agent-history` build
their route before the decision rather than after it, because the
decision needs to know whether the shell is a possible outcome at all.
`web` already had this frame inline and now takes the shared one; its
spinner's accessible name moves from "Checking host" to "Loading".

The two cases that pinned the old behaviour — "renders the native panel
while the flag read is still settling" on the files and agent-history
routes — now assert that neither renderer mounts there.
`shell-switch-null-flag.test.tsx` drives all nine switched routes
through the three states and counts committed mounts rather than
renders. Five route tests gain a `react-native` mock, which the neutral
screen's `View` is the first thing in their graphs to need.

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

* test(mobile): fence the neutral state across every hybrid shell switch

Reading the flag through the shared decision is not on its own enough.
A tenth switch could ask `useShellSwitchDecision`, ignore `pending` and
fall through to its native screen, satisfying the reader rule and still
flashing native in front of a flag-on user. So the census also says
every switch names the neutral screen — existence, not shape; where it
names it is the route tests' business.

`matchesOf` is the snippet reader beside the three rules: the needles
are identifiers, and a list of paths says which file moved but nothing
about what in it did. Verified as a fence by deleting the `pending`
branch from the tasks switch, which the rule caught and named.

* test(mobile): measure what the neutral window costs a released phone

The only thing this change costs a user with the flag off is the window
itself, so it is worth a number rather than a claim.
`loadMobileWebShellEnabled` answers `false` outside `__DEV__` before it
looks at the key, so a release build reaches AsyncStorage zero times:
the window is React's own passive-effect flush and one microtask, not a
bridge round trip, and the switch has its answer on the first turn after
the first commit. Pinned per switch, because a reader that grew a
storage call would move it from a microtask to a bridge hop.

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

* test(mobile): type the switch table so the tests-typecheck ratchet reads it

`as const` on the table made the catch-all's `page` a readonly tuple,
which `useLocalSearchParams`' own param type does not admit, and the
file dropped out of `tsconfig.test.json`. An explicit element type says
the same thing and checks.

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

* fix(mobile): keep release builds out of the neutral state entirely

Review round 1 (pullfrog). The hook started at `null` on every build, so
a store build committed one neutral frame before its native renderer —
the one cost this change landed on every released phone, and it bought
nothing there, because the flag cannot be turned on outside `__DEV__`.

`mobileWebShellFlagCanBeOn` names that build-kind test once, beside the
reader that already made it, and the hook starts its state on the answer.
Outside `__DEV__` the hook holds `false` from its first render, the
`pending` branch is unreachable, and a store build commits native on
frame one. The effect still runs and still answers `false`; the
initialiser is a starting point, not a second read path.

Red-first, both build kinds pinned rather than inherited from the runner:
18 of 54 cases failed — "commits native on its first frame" and "does the
same when the bundler defined no `__DEV__` at all", nine switches each.
The neutral screen is mocked with a mount counter now, because a frame
committed and replaced inside one `act` leaves nothing in the tree; its
shape stays pinned in the web route's test, which renders the real one.
The census gains the build-kind fence as a third rule.

Jinwoo Hong 3cfb070294 feat(mobile): register the session page route (OTA phase C, C7.7) (#21977)
* feat(mobile): switch the session route to the shell, still unregistered (OTA phase C, C7.7)

The review switch's shape, for its reasons. The session screen becomes
`MobileSessionRouteScreen` in `src/session` because `useMobileSessionController` is 32 hooks
deep and opens the terminal, chat and tab subscriptions: at the switch's top level it would
open every one of them behind the page as well as in front of it, since hooks cannot be
conditional. As an element passed for `fallback` it is built and not mounted.

Four query params carried rather than re-derived, each omitted when empty: `name` is a label
the screen otherwise derives from the workspace, `created` is the create flow's one-shot flag,
`warning` is the host's own text, and `paneKey` is a notification tap. `paneKey` is the one the
screen writes back — `use-notification-pane-navigation.ts` rewrites it to empty once it has
switched, through `setParams` on the handoff, which inside the page is the document's own
router — so it has to arrive in the page for that to happen at all.

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

Three censuses red without their rows, measured on this tree:
- `shell-screen-route-census.test.ts` `walks the route tree and finds them` named
  `session/[worktreeId].tsx` as a ninth switch the list did not have.
- `mobile-web-shell-flag-census.test.ts` `reaches the switched routes through that hook and no
  others` reds without `SESSION_ROUTE` in `SWITCHED_ROUTES`.
- `mobile-web-app-web-overrides.test.mjs` `lists exactly the .web.* files on disk` named the
  new sibling.

* test(mobile): root the session parity family at the screen the route mounts (OTA phase C, C7.7)

The extraction parity pin walks from a root function in `app/h/[hostId]/session/[worktreeId].tsx`,
which is now the flag switch: the walk found no `SessionScreen`, and the runtime-string count went
534 -> 542 on the switch's own param names and path literals.

Rooted at `MobileSessionRouteScreen` instead, which is the function that calls the controller. The
switch's business is which of the two screens renders, not what the session screen does, and its
literals have no place in a hash about the extraction.

Every pinned hash is unchanged, which is what says the body moved and nothing else did: 275 hooks,
77 callbacks, 24 effects, 534 runtime strings, 124 host and 61 leaf JSX facts, 172 style
references, all at the same SHA-256 they had before the move.

* feat(mobile): give the page the session screen's stored preferences (OTA phase C, C7.7)

Ruling 7: nothing silently no-ops. The allowlist was one exact key and one prefix, so every
preference the session screen reads inside the page fell back to its default and kept working
outside it — a state the user cannot tell from a preference that does not exist.

The keys are derived from the route's own closure, not copied from design §6. Nine join the list:
`orca:terminal-accessory-layout`, `orca:custom-accessory-keys`, `orca:defaultSessionView`,
`orca:mobileStructuredSendOperations:v1`, the three terminal preferences ruling 7 names
(`orca:terminalTextScale`, `orca:terminalAutocompleteEnabled`, `orca:terminalLinkOpenMode`), and
two the design did not: `orca:hostDockWidth`, which `use-mobile-dock-resize.ts` drags on this
screen, and `orca:hostSidebarWidth`, which `app/h/_layout.tsx` reads above every page route and
which the manifest already names as the reason agent-history declares `storage` at all.

Two are per workspace, not per host. Design §6 has `orca:nativeChatTabs:<worktreeId>`; the module
builds `<prefix><enc(hostId)>:<enc(worktreeId)>`, and `orca:terminalLiveInputDisabled:` has the
same shape. So the narrowing goes one level in from C2.9's: `pageStorageKeysForRoute` and
`isPageStorageKeyForRoute` replace the host-scoped pair, and a session page opened on one workspace
can no more rewrite the tabs of the one beside it than it can another host's pins. Both sides read
the workspace off the route pathname, which is the one fact the shell and the page are each handed.

Every new key's writer notes the mirror before it persists, as `savePinnedIds` does: `init` is
built synchronously, so a write that only reached the store would be one `init` behind.

A refusal is a rejection, not a dropped write. The real AsyncStorage rejects when its store
refuses, and the caller that matters already catches: the durable send journal answers
"Message not sent" rather than putting a mutation on the wire with an operation id no store holds,
which after a crash would send the message twice. `PageStorageRefusedError` names the key and which
of the three refusals it was.

Measured on this tree, which is why the journal needed more than an allowlist entry: one journal
entry with no attachment serializes to 342 characters and 48 unsettled sends put the value past
`PAGE_STORAGE_MAX_VALUE_CHARS` (47 is under it), against a schema that admits 4,096. `init`'s own
`BridgeInitStorageSchema` refines on that bound, so handing the journal over whole refuses the
*frame* and the session screen never opens at all. `pageStorageEntriesForInit` drops such a value
and names it; the page reads a default, which is a degradation rather than a page that does not
start.

Red first, measured here:
- 21 cases across three files on the host-scoped helpers being gone.
- `leaves out a value the page would refuse the whole frame over` reds with the filter bypassed.
- The journal case reds without the rejection, with the operation claimed against a store that
  never took it.

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

* feat(mobile): register the session page route (OTA phase C, C7.7)

One entry in `MOBILE_WEB_PAGE_ROUTES` with ten grants, every one read off a call site in this
route's own closure rather than carried from design §1. Measured here:

  navigate                 7 handoff sites
  externalLink             6 openers
  haptics                 24 trigger sites
  native.clipboard.write   6 sites
  native.clipboard.read    3 sites
  native.media.*           2 sites, one seam (`useMediaPicker`)
  screencastBinary         1 site (`MobileBrowserPane.tsx`)
  storage                 10 exact keys and 2 workspace-scoped, the previous commit's

`pageRouteGrants` is derived from this list, so the row is a consequence of the entry and there is
no second table to edit. The design's list was exactly right; the counts are what say so.

The hop census goes 16 -> 23, measured. All seven new rows are `X -> /h/[hostId]/session/
[worktreeId]`, one from each other page route, and none goes the other way: the session's ten
grants are a strict superset of every other route's, so every hop into it is handed to the shell
and every one of its own targets stays in the document. That second half is asserted as grant
coverage rather than as the absence of seven rows — absent is also what an unregistered route
looks like, which is the shape C4 already had to correct once.

Two censuses gained the route and one is new:
- The haptics seam census, whose route-module map moves to
  `mobile-web-app-page-route-modules.mjs` so the new census below shares it rather than keeping a
  second copy that stops growing when the first one does.
- `page-served-back-control-a11y.test.ts`, which named two controls with no `accessibilityRole`:
  `MobileSessionHeader.tsx:64 role=none label=Back to worktrees` and
  `QuickCommandsSheet.tsx:160 role=none label=Back`. Both get the role. Inside the shell there is
  no native chrome behind them, so a bare Pressable is absent from the accessibility tree.
- `mobile-web-app-screencast-lane-grant.test.mjs` derives `screencastBinary` from the closures the
  way the haptics census derives its token. C6 could not write it: the pane is mounted by a route
  rather than registered as one, so there was no route to pin the grant against (C6 ruling 3).

The derivation census gains C6's half measured against this route rather than against a module
closure read on its own, which is the other half of C6 ruling 3. The composed row for the session
route's own families waits on C7.8's table, and on C4.5's split before it.

Numbers, both ends measured on this tree, never summed:
- Session route closure 4,328 -> 4,329 modules, 978 -> 979 local. The +1 is
  `MobileSessionRouteScreen.tsx`; the route file is one input either way, now the `.web.tsx`.
- Chunk count 65 before and 65 after, against the 72 the fence allows at 14 route keys. The fence
  is untouched: a `.web.tsx` sibling is not a new route key, and this route shared its split.
- Bundle 8,020,519 -> 8,022,202 bytes, 108 assets either side.

`mobile-web-app-route-chunk-closure.mjs` looked the route module up by its exact path, and
`resolveExtensions` puts `.web.tsx` first: the first route with a sibling to be asked for reached
"no output". It tries the sibling first now, which is what the build actually chunked.

Without the manifest entry these red on this tree: `pins every hop the handoff must take away from
the page`, `keeps every hop out of the session local`, `declares only routes the bundle has a
module for`, `reaches the built manifest`, `covers every page route and finds a control in each`,
both haptics-seam cases, and `declares the screencast lane on exactly the routes whose closure
asks for it`.

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

* test(mobile): render-check the session route, and quiet the two things it found (OTA phase C, C7.7)

The render check mounts the registered route in a real browser on the built bundle, under the
header the shells send. It asserts the session screen paints rather than the Unmatched route, that
the Back control reaches the accessibility tree as a real `<button>` with its name, that the
route's own chunk arrives on a client-side navigation, that nothing it paints leaves the origin or
logs a policy violation, and that the three reads the screen makes carry the workspace the route
named — the precondition the rest needs, since a screen that mounted and asked for nothing would
paint the same chrome.

It also asserts, strictly, that the page and console errors are `[]`, which is what found both
fixes here. Measured on this tree before them: two console lines and one uncaught rejection on
every mount of the route, none of them visible natively.

- `use-mobile-session-markdown-actions.ts` registered `BackHandler.addEventListener` with no
  platform guard, and the effect re-registers whenever the dirty-draft list changes. React Native
  Web answers "BackHandler is not supported on web and should not be used." and hands back an inert
  subscription, so the guard was never armed on the page anyway. Gated on `Platform.OS`, as the
  right drawer, the bottom drawer and the file preview already are. There is no hardware back in a
  WebView; the shell owns the phone's, and the page's Back control is where the prompt lives.
- `use-mobile-session-diff-comments.ts` ran `void loadDiffComments()` in an effect with no catch.
  The loader returns on a *refused* `worktree.show` and nothing caught a *rejected* one, so a host
  that will not answer produced `Uncaught (in promise)` on every session mount. Caught at the
  effect rather than inside the loader, whose promise the golden recorder awaits; notes that did
  not arrive leave the ones on screen as they were, which is the module's own policy for a refusal.

**The terminal is not painted here and the file says so at both ends.** A terminal on screen needs
the host protocol handshake, a tab snapshot, a terminal inventory and a `terminal.subscribe`
stream — five hand-written fixtures against five Zod schemas inside a transport double, which is
what the harness's docstring refuses to become. Scripting `status.get` alone was measured here:
the protocol gate reads it and the page paints "Update Orca on your computer" instead of the
screen. What the terminal does under the shipped header is
`mobile-web-app-terminal-render.test.mjs`, on the same component and the same build options.

* test(mobile): refresh the session parity pins for the two seam edits (OTA phase C, C7.7)

The previous commit's two fixes are inside the parity family, so three pins moved. Both edits are
one token each and neither changes what a phone renders:

- `'web'`, the `Platform.OS` guard the Markdown actions' `BackHandler` registration gained.

* fix(mobile): report the diff-notes rejection instead of catching it (OTA phase C, C7.7)

The `.catch` the previous commit added to `loadDiffComments` moved a golden, which is a finding
rather than something to record over: `matrix-session.diff-notes-worktree.show-1` certifies the
unhandled rejection as an effect of its loaded checkpoint, so the corpus says the app raises it
today and a fix is a re-record and a review event.

Reverted to `void loadDiffComments()`, with the defect written where a reader of that effect will
find it. `family-recordings.test.ts > session.diff-notes: reply partitions at worktree.show#1` is
green again; it was the one failure in an otherwise clean 8,699-test run.

The render check keeps the observation rather than losing it. Its error assertion is now the exact
list `['RenderCheckShellDouble: the render check answers no RPC']` instead of `[]`, so a second
error reds it and so does this one going away — which makes the file the place the fix is noticed
when someone lands it with the re-record.

The defect, for that PR: the loader returns on a *refused* `worktree.show` and nothing catches a
*rejected* one, so a host that will not answer raises an unhandled rejection on every session
mount. It is not a page fault — the shell's `fault` notify comes from the React boundary and
nothing reaches it — so the generation is not dropped and the screen works; the cost is a
document-level error on every mount.

* test(mobile): repin the session effect hash after the diff-notes revert (OTA phase C, C7.7)

The effect pin was refreshed while `loadDiffComments` carried a `.catch`; reverting that (the fix
moves a golden, so it is a finding rather than a line) moves the same hash back off it. Repinned on
the uncaught `void` call, which is what the tree holds and what the corpus certifies.

Count unchanged at 24 effects; nothing else in the family moved.

* fix(mobile): reject a page storage write for size only, and log the rest (OTA phase C, C7.7 round 1)

Ruling 33.4. `PageStorageRefusedError` was raised for all three refusals, and two of them have no
catcher: a page-closure writer of an unlisted key awaits `setItem` with nothing around it —
`notification-delivery-preferences.ts:39` plainly, `preferences.ts` in several places — so a key
the page was never allowed to keep became an unhandled rejection in the document. That is a worse
failure than the silent drop it replaced, and it is the one the page can least afford, because an
uncaught rejection there is a document-level error on a screen that is otherwise working.

Scope is now one refusal. `too-large` rejects, because the caller that needs it is written for it:
the durable send journal's composer catches it and answers "Message not sent" rather than sending a
mutation whose operation id was never written down (ruling 7). `not-allowed` and `not-delivered`
resolve and are logged as `[page-bridge] storage-write-dropped`, which is the old behaviour plus
the line a device log needs — a preference that did not stick looks identical to one nobody set.

A batch applies every pair it can, logs every drop, and rejects only if one of them was oversize.

Red first, measured here: seven cases in `page-async-storage.test.ts` red on the rejection, among
them a `notificationDeliveryPreferences` write resolving, another host's pins, another workspace's
chat tabs, and a write the shell would not take. The oversize case is unchanged and still asserts
`PageStorageRefusedError` with the key and the character bound in its message, so the narrowing is
visible as the difference between the two.

* docs(mobile): make every count in the session route say the same number (OTA phase C, C7.7 round 1)

Ruling 33.5. Three numbers were stated more than once and two of them had drifted when the merge
took the grant list from ten to fourteen.

- Grants. `mobile-web-page-routes.mjs:100` and `mobile-web-page-route-hop-coverage.test.mjs:57`
  both still said ten. Fourteen in both, and the manifest comment now names the audio verbs beside
  the media ones as things only this route asks for.
- Keys. The manifest said `storage` covers "the ten exact keys and two workspace-scoped ones",
  which counts `orca:last-visited-worktree` — a key this route did not add. Nine exact plus the
  two workspace-scoped, which is what C7.7 put in `page-storage-keys.ts`.
- The journal entry. 342 and 343 are both real and answer different questions, which is exactly
  why one number had to win: an entry serializes to 342 characters on its own and costs 343 in the
  array, the difference being the comma that joins it. 343 is the one that drives the threshold,
  so it is the one stated, with the 342 kept beside it as its derivation. Re-measured here rather
  than carried: 47 entries are 16,140 characters and 48 are 16,483, against the 16,384 cap.

Comments only; no behaviour and no assertion moved. The threshold case in
`mobile-structured-send-page-storage-refusal.test.ts` already asserted the boundary both ways and
still passes unchanged, which is what says the arithmetic above is the code's and not the prose's.

* test(mobile): red-first for a pane request over a re-sent init (OTA phase C, C7.7 round 1)

Ruling 33.1's four cases plus the compatibility one, all red: `publishRoute`
is not a member of the host, `onRouteUpdate` is not a member of the page's
client, and `ready` carries no `accepts`.

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

* feat(mobile): deliver a pane request to the mounted page over a re-sent init (OTA phase C, C7.7 round 1)

Ruling 33.1. The session switch keyed on the whole route, so a notification
tap for another pane of the session on screen either remounted the shell (a
bridge teardown and a page reload for a tab switch) or, for the pane already
showing, moved nothing at all: the page cleared `paneKey` on its own router
and the native param kept it, so `SET_PARAMS` wrote the value already there.

`paneKey` leaves the key and travels as a route update. The page declares
`accepts: ['route-update']` on `ready`; the shell re-sends `init` for a
same-path param change only to a page that declared it, and treats a second
`init` for the session the page already holds as a route update rather than a
replacement -- in-flight requests, subscriptions, the storage snapshot (the
same object, asserted) and the generation all stay. The screen reports
delivery and the switch clears the native param, so no later `init` replays a
spent tap. `use-notification-pane-navigation.web.ts` reads the request off a
standing listener; the native file is unchanged.

Wire-compatible both ways without a version bump: `accepts` is optional, an
older page is never sent a second `init`, and an older shell never sends one.
Both degrade to today's lost repeat tap. `BRIDGE_PROTOCOL_VERSION` and every
released native RPC are untouched.

Two files were at their line cap, so two modules came out at their own
boundaries rather than a cap bump: `bridge-init-route.ts` (the route half of
`init`, wanted by the switches, the host and the page) and `bridge-host-route.ts`
(one host's held route and what it may publish).

* test(mobile): the session switch and its hardware-back gate get their own tests (OTA phase C, C7.7 round 1)

Ruling 33.2. `mobile-web-shell-session-route.test.tsx` mirrors the eight cases
the files switch has -- route built, native fallback while the flag settles,
repeated params, dot-segment refusal, segment encoding, flag off, remount on a
route change, remount on a param change -- plus the two pane cases: a repeat
tap for the same pane reaches the mounted page twice and a different pane
reaches it once, both with one mount in the lifecycle.

The `BackHandler` gate gets a unit test in the shape of its three siblings.
Reaching it meant the hook declaring the fourteen fields it reads instead of
taking all 268 of the session model, so a probe can render it without building
a session; `MobileSessionDiffCommentsModel` satisfies that by construction and
the one caller is unchanged. No pin in the session parity census moves.

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

* test(config): a call-site census for the six grants that had none (OTA phase C, C7.7 round 1)

Ruling 33.3. `navigate`, `storage`, `externalLink`, the two clipboard verbs
and the media three were pinned only by the list they were copied from, so
striking any of them out of a manifest entry reddened nothing. Each is now
derived from the route's own closure by parsing the call sites -- a call, not
a mention in a comment or a string, and not an import the module never calls
-- and each row has a named control case driven over the session entry with
that row's grants struck out.

It found one thing. `app/h/_layout.tsx` wraps every `/h` route in
`HostProtocolGate`, whose wall offers an Update Orca link through
`openExternalLink`, and two routes reach that without declaring
`externalLink`: on them the link posts a notify the shell refuses. Recorded
exactly as `KNOWN_UNDECLARED` rather than exempted, because widening two other
routes' grants is a capability decision and this is pre-existing on main.

`notificationPaneTab` moves to its own module. A `.web.ts` sibling cannot
import its native neighbour by the plain path: the bundler's
`resolveExtensions` answers with the `.web.ts` file, so that import was the
file itself and esbuild refused the page bundle with a cycle. The mobile suite
does not bundle, so only the closure walk saw it.

* test(config): make a struck-out grant red a case named after it (OTA phase C, C7.7 round 1)

The first shape checked the whole manifest at once, so removing any one of
the eight reddened all seven cases and named none of them: the per-row control
read `session.grants` off the manifest the removal had just changed. Each row
now has its own manifest case, and each control is built from what the
session route's closure reaches rather than from what its entry declares, so
it stays green whatever the manifest says. Closures are memoised, which is
what pays for walking all eight once per row.

* fix(mobile): hold the pane request in a ref, not in state (OTA phase C, C7.7 round 1)

The changed-code quality gate's React Doctor found it:
`no-adjust-state-on-prop-change`. A tap can arrive before the terminals have
loaded, so the request has to wait; holding it in state meant the effect that
consumed it set state on a prop change, and the stale selection renders first.
The request waits in a ref now and a counter wakes the effect, so the effect
reads and clears rather than adjusting anything.

* test(config): re-measure the session closure and list the new web sibling (OTA phase C, C7.7 round 1)

The full `config/scripts` suite found both. The closure reads 4,326 modules
and 984 local, two more than the merge, and the two are named rather than
counted: `notification-pane-tab.ts` and `bridge-init-route.ts`. The pane
hook's web sibling replaces the native file rather than joining it, so it
costs nothing -- but it is a `.web.ts`, so it needs its row in
`web-overrides.json` saying why the native one cannot run on the page.

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

* fix(mobile): keep the page off a journal init could not carry (OTA phase C, C7.7 round 1)

Ruling 33.6, from pullfrog on `beda1cc384`. Dropping an over-cap value from
`init` did not revoke the page's write access to it: the key stays in
`pageStorageKeysForRoute`, so the page read no journal, `parseJournal(null)`
gave it an empty one, and its first send wrote a one-entry value over the
device's -- every native entry lost and a fresh `operationId` for an operation
the native journal already held, which is the duplicate send ruling 7 exists
to prevent.

`pageStorageEntriesForInit` now reports `oversize` beside `dropped`: only the
value-cap drops, because an entry-cap drop is a key that fits and the page's
own write of it is the size the shell would have carried anyway. The shell
sends those names as `init.storageOversize`, and a page write to one of them
rejects with `PageStorageRefusedError` under the size contract of 33.4, which
the composer already shows as "Message not sent". The native journal is
untouched until the user is back on native or it drains.

`storageOversize` is optional in both directions: an older shell sends none
and an older page ignores it, which is exactly today's behaviour. No version
bump; omitted rather than sent empty, so no golden moves.

Red first, with the two states replaced by ones the shell produces. The 47/48
case drives `pageStorageEntriesForInit` rather than publishing a journal value
the shell strips before `publishPageStorage` ever sees it, and the case that
used to assert a successful write now asserts the native entries survive: it
was the clobber, recorded as success.

* fix(mobile): deliver a route update only when a param moved, and only after init went out (OTA phase C, C7.7 round 2)

Round 2, findings 1 and 2, both red first.

`onRouteUpdate` fired on every re-sent `init` for the session the page holds,
not only on one whose route moved. The shell answers every `ready` with the
route it holds and the page re-asks on its own backoff and again after a
refused `state` frame, so one tap reached the pane hook as `['', 'pane-1']`.
Both ends now read one definition of moved, `bridgeRouteMoved`, which is the
page's own `shellScreenRouteKey`: the host will not send an `init` for a route
that did not move and the page will not publish one it was sent anyway. The
`.web.ts` hook keeps its empty-pane guard and its comment now says why it is
load-bearing rather than defensive -- the shell's own clear arrives as a move.

`onRouteDelivered` ran on the `ready` path without checking that an `init` had
gone out. A refused route answers the ask with nothing, so the caller would
clear a one-shot param the page never received. `sendInit` reports whether a
frame left and `onPageReady` carries it. Unreachable from the session switch,
which parses the route before it mounts the shell; the prop's contract says it
anyway, and the publish path already honoured it.

* docs(mobile): attach the init-storage doc to its type, keep the overrides escape (OTA phase C, C7.7 round 2)

Round 2, findings 4 and 5, neither a behaviour change.

The block describing `pageStorageEntriesForInit` had `PageStorageForInit` and
its own one-line doc between it and the function, so it documented neither.
The type moves above it and the block sits on the function it describes.

`web-overrides.json` had an escaped em dash re-encoded as a literal one when
this branch added its rows through a JSON round trip, on a line about the
keyboard stub that has nothing to do with C7.7. Main's `—` is restored;
`oxfmt --check` accepts the file either way, so this is main's spelling kept
rather than a formatter's demand.

* fix(mobile): catch the custom-key save the page store refuses (OTA phase C, C7.7 round 2)

Round 2 addendum. `addKey` awaited `saveCustomKeys` with no catch and both of
its callers are `void addKey(...)`, so the rejection had nowhere to go.
`orca:custom-accessory-keys` is in the session route's page allowlist and a
page write over `PAGE_STORAGE_MAX_VALUE_CHARS` rejects rather than drops (the
size contract of 33.4, extended by 33.6 to a key `init` could not carry), so
past ~16 KB of accessory keys this surfaced as an unhandled rejection in the
page -- which the fault boundary reports and which drops the generation.
Every other allowlisted writer in this closure already catches: the two write
chains in `TerminalShortcutSettings`, the live-input save and the session-view
preference.

Caught at the boundary and logged, and the drawer neither announces the key
nor closes: a row on the accessory bar that no store holds, gone at the next
load, is the failure the allowlist exists to avoid. Red first -- the case saw
the refusal escape with the page's own message -- and the control reds again
when the catch rethrows.

Belongs in `8b4c559e90` by the brief; it is its own commit because that one
was already made and amending is forbidden.

* fix(mobile): reject a batch of oversize writes once, not once per pair (OTA phase C, C7.7 round 2)

CodeRabbit and pullfrog, same site. `settleBatch` called `settle` per refusal
and kept the first rejected promise, so a `multiSet` or `multiRemove` with two
over-cap pairs built a second rejected promise nobody held -- an unhandled
rejection in the page, the outcome ruling 33.4's rejection scope exists to
avoid. Two oversize keys is all it takes, and `storageOversize` made a second
way to reach it.

A refusal is now an error or nothing, and only the caller's one rejection ever
becomes a promise. Red first under an `unhandledRejection` listener with two
over-cap pairs: one orphan before, none after, and the caller still hears
about the first key.

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

* fix(mobile): record a route key only once a frame carried it (OTA phase C, C7.7 round 2)

CodeRabbit on `MobileWebShellScreen.tsx:271`. The effect recorded the route's
key and then published, so a publish the hook refused for having no host was
remembered as though it had gone out. `publishRoute` is now keyed on
everything the host is built from rather than on the session alone, so the
render that brings the host re-runs the effect, and the key is written only
after a frame has left.

Reported honestly: this does not repair a lost tap, and the case beside it
says so. The host is built from the route the render holds, so a route that
moved before it existed rides the first `init` either way and `publishRoute`
then answers "did not move". What the change removes is a key recorded for a
frame nobody sent -- the same contract finding 2 fixed on the `ready` path.
The case pins the delivery count across the gap: nothing reported while there
is no host, nothing reported once there is one and it has sent nothing, and
exactly one report when the `init` answering the page's ask carries the route.

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

* fix(mobile): refuse an oversize-dropped key at the shell, not only at the page (OTA phase C, C7.7 round 2)

pullfrog's rollout gap on ruling 33.6. `storageOversize` is honoured by a page
built with it, and the page is served from the desktop: a document from an
older bundle ignores the field and writes the key whole, which for the send
journal replaces every entry the device holds. The shell is the half that
updates with the app, so the shell is where the refusal has to live.

The host now refuses a `storage` notify for a key it could not hand the page,
answering it as the drop it already answers an unlisted key with. The page's
own rejection stays as the fast path -- it reaches the composer as
"Message not sent" with no round trip -- and the schema comment says the field
is advisory and the shell enforces it.

Red first: a host holding the journal as oversize received a page write for it
and posted it to native storage; now it posts nothing and the entries survive,
while a key it did hand over is still writable.

The three refusals became one predicate in `page-storage-keys.ts`, where the
keys are, because inlining the third put `bridge-host.ts` over its line cap.

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

* test(mobile): the page's pane hook gets its own test (OTA phase C, C7.7 round 2)

pullfrog: `use-notification-pane-navigation.web.ts` had no cover. The native
file's test mounts the native file, and `bridge-route-update.test.ts` stops at
the client, so the half that turns a route update into a tab switch was
untested.

Seven cases: the seed from the route the page was opened on, a request held
until the terminals load, a repeat tap on the pane already showing, a
different pane, the clear the shell posts after each delivery, a pane that has
since closed, and a page opened on no pane at all.

Two controls, so the cases are not all satisfied by one behaviour. Dropping
the seed reds the two that read the first `init`. Deduplicating by value
instead of counting deliveries reds the repeat tap, which is the case the
counter exists for.

* fix(mobile): roll the custom-keys mirror back when the store refuses (OTA phase C, C7.7 round 2)

CodeRabbit. `saveCustomKeys` notes the write in the mirror before it persists,
because a reader is answered from the map rather than from the store and the
shell builds `init` synchronously from that map. On a refused write the note
stood: the page's next `init` carried the value native had rejected, and every
native reader of the key saw it too.

The previous mirrored value is captured and put back on the failure path, and
the error still goes to the caller so `addKey` keeps withholding the key.

Red first: with the store refusing, the mirror held the rejected value where
the pre-save value belonged.

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

* fix(mobile): report a route delivered only after its frame was posted (OTA phase C, C7.7 round 2)

CodeRabbit on the send path. `sendInit` answered "sent" the moment it handed
the JSON to `post`, and a rejected post was reported a turn later as a
diagnostic -- so the screen spent the one-shot `paneKey` on a frame the page
never received, cleared the native param, and the tap was gone. `publishRoute`
was fire-and-forget the same way.

Delivery is a promise now, settled after `options.post` resolves and false on
either throw or reject. Readiness stays separate: `onPageReady` fires on the
ask, as the shell's wait needs, and carries the delivery promise beside it.
The screen records the route key and calls `onRouteDelivered` only when that
promise answers true, and a refusal leaves nothing recorded so the next render
that can carry the route tries again.

Red first: with the view refusing what it was handed, the frame was built and
posted and the screen reported delivery anyway. Now it reports none while the
page's ask is still reported, and a host-level case pins the same split.

`bridge-host.ts` was at 299 of 300 lines, so the send half came out as
`bridge-host-frames.ts` rather than growing it; the file now measures 280.
The screen's own test harness never attached the view handle, so every post in
it rejected unobserved -- it attaches one now, which is what let the case see
the frame at all.

* docs(mobile): fold two doc blocks back onto what they describe (OTA phase C, C7.7 round 2)

pullfrog's two nits, no behaviour change. `page-async-storage.ts` kept the old
`settle` block above `refusalError` when the function it described moved down
with a one-liner of its own; the orphan goes. `bridge-host.ts` had two stacked
blocks on `sendInit` after it grew a return value; they are one, and it now
says the frame is still built synchronously and only the post is awaited --
which is the property the golden recorder depends on.

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

* fix(mobile): let the host own a pending route until its frame lands

A route the page has not received is now the host's, not the screen's. `publish` keeps it
pending until a post resolves true, marks it delivered only then, and reports that through a
callback registered once per host. Movement is measured against what a frame actually reached
the page with rather than against what the host holds, so a refused frame leaves the route owed
instead of reading as one that did not move.

Three things the old shape lost, each a case here: a frame the view refused was never retried,
because only another render could try and a mounted page has none coming; a render while a post
was in flight cancelled the report the switch spends to clear the param; and a repeat tap for
the same pane was held, because the host had already moved its held route on the attempt that
failed. The retries are the moments delivery becomes possible again — the next `ready`, and a
view handle the host regains — and one frame goes out at a time.

Also folds round 4's doc nits: the stale delivery comment the screen no longer has a ref for,
and a leftover `an` in the `ready` branch.

* fix(mobile): roll the journal mirror back when persistence fails

`writeEntries` noted the mirror before the store took it, which is what keeps an `init` built in
the same turn current — but it kept the note when the store refused. The page then received a
journal the device never wrote and resumed operations nothing was holding.

Restored on the error path, the same shape as the custom-keys save, and on both halves: the
removal that empties the journal had the same gap as the write that fills it.

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

* fix(mobile): keep publishing until the held route is the delivered one

Two halves of the same gap, both found by the bots on `fba8cb3f3d`.

A route that moved while a frame was out was held for the turn and then had nothing to wake it:
the post settling only cleared the in-flight flag, and on a mounted page no `ready`, handle or
tap need ever come along. A landing is now itself a moment to publish again, while what the host
holds is not what the page has. Only on a landing — a refused post that re-attempted itself
would spin, and that one still waits for whatever makes delivery possible again.

And the report carries the route a frame reached the page with, which the session switch was
ignoring: the older pane landing wiped the `paneKey` naming the newer one, so the page stayed
where it was and the second tap was gone. The switch now spends the param only for the pane that
was delivered.

The delivery cases render through one helper rather than six copies of the same setup, which is
what keeps the file under its cap.

* docs(mobile): drop the second block describing a parameter onPageReady no longer takes

The field is documented by the block above it; this one still described the `delivered` promise
the handler was handed before the host took ownership of the pending route.

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

* feat(mobile): let the page erase the route param it was handed

Ruling 34, step one: one page-to-shell frame that asks the shell to clear a one-shot route param,
naming the value the page applied.

Closed at both ends. The param is an enum of what the shell hands over, so a page cannot edit a
route it was never given; the notify name is a member of the closed union, so it gets a row in
the grant table by compilation rather than by memory, and rides no grant because it can only
spend something this shell put there. The shell declares it in `init`, the mirror of
`ready.accepts`: no shipped shell serves a page, so nothing needs negotiating today and the
page's check exists from the first version that can post one.

The comparison belongs to whoever holds the param, which is the session switch: a tap that moved
on while the page was applying the one before it leaves a newer key, and a clear naming the older
one is not for it.

`bridge-envelope.ts` went over its cap, so the page-to-shell union moved to
`bridge-notify-envelope.ts` and the fields both halves spell to `bridge-frame-fields.ts`, which
the envelope re-exports. No cap was raised.

* refactor(mobile): re-send init on a route change and track nothing else

Ruling 34, step two: the tracked handoff is gone. Deleted, not patched — the pending route, the
delivered route, the in-flight flag, the landing callback, `retryPendingRoute`, the delivery
promise `onPageReady` used to carry, and the `onRouteDelivered` that ran from the host through
the hook and the screen to the switch.

What is left is the rule in one line: `publish` sends one `init` when the route moved and the
page said it takes one, and every `ready` is answered with the route the shell holds then. A
frame the view refused is repaired by the next ask, not by a retry; the request it carried is
spent by the page.

The cases that tested the deleted mechanism go with it. The outcomes they protected are pinned
where they now live: one frame per move and none for a render that moved nothing, a lost frame
repaired by the next ask, no second `init` to a page that never said it takes one, and the
repeat tap measured through the page's erase rather than through a delivery report.

* feat(mobile): the page applies a pane and erases the request that carried it

Ruling 34, step three. The page hook applies the pane an `init` names and asks the shell to erase
the param it came on, naming what it applied.

Two rules, and both are the page's because the shell has none. The erase is asked for on every
`init` that carries a pane rather than only on the one that changed something: a clear that never
reached the shell leaves the param in place, and the next frame carrying it is the repair. The
switch happens once per value: a re-asked `ready` is answered with the route the shell still
holds, and applying that again would drag the page off a tab the user has since moved to.

A repeat tap for the same pane still arrives as a request, because the erase went through in
between and the tap wrote the param back. The client refuses to post the frame to a shell that
did not declare it takes one, which is every shell older than the field.

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

* fix(mobile): keep the page bundle's readers pointed at the module that declares each name

The envelope split left three source-text readers and one import pointed at a file that now
re-exports what they read.

`shell-screen-route.ts` read the route schema back through the envelope, which reaches that file
again through the page-to-shell union: a cycle esbuild resolves to `undefined`, so every page
route mounted onto a schema that was not there yet and the browser render suite failed on twelve
files with a TypeError rather than on a build error. It reads the declaring module now.

The render harness read `BRIDGE_PROTOCOL_VERSION` and `BRIDGE_FAULT_GRANT` out of the envelope by
regex; both moved, and a regex over a re-export answers for whichever file the last split left
them in. Both point at `bridge-frame-fields.ts`, and the throw names it.

The session route's page closure is re-measured on this tree at 4,330 / 988 and the four new
modules are named, not inferred: the two halves of the split envelope, and the route-update
module and route-key reader the page-to-shell union now reaches through it.

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

* test(mobile): count posted inits with the page's own reader, not a cast

The changed-code quality gate refuses a type assertion, and it is right to here: a frame the
page's reader would refuse is not an `init` the page ever saw, so a case counting them must not
count one either.

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

* refactor(mobile): put every mirrored write on one path that notes what the store took

Ruling 35. Fourteen call sites in six files noted the shell's mirror before persisting, and on
the page a persist can be refused: twelve left the map holding a value no store had taken, and
the next `init` handed the page exactly that. Two undid it by hand.

`persistMirrored` is the one path now, and it seats the map from what the store holds after the
write rather than from what it was handed. That is what makes the note follow acceptance without
a second opinion about it: the page's adapter resolves a `not-allowed` write and logs it, so a
rejection is not the only refusal there is, and reading back is the only answer that covers both.
The cost is one store read per mirrored write on the device, where the store refuses nothing.

`writeMirroredStorage` keeps its note-then-persist order and loses every caller but one: the
shell taking a value the page has already applied, into the device store, which has no allowlist
and no frame cap to refuse against. It builds the next `init` synchronously in the same turn, so
noting on the store's reply there would hand the page back the value it just changed. The
last-visited key moved off it, because that module is in the page's own closure.

Both rollbacks are gone with the notes that needed them, and `noteMirroredWrite` is private. A
source-scanning census holds each writer to the path by name.

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

* refactor(mobile): answer a page batch write at the first pair it cannot take

Ruling 35's other half. `settleBatch` collected a refusal per pair, logged each, and rejected
with the first that could reject while the rest of the batch went in anyway — one promise
describing a call where some pairs landed and some did not, which is not something a caller can
act on.

A batch is one call with one answer now: every pair before the refusal is applied, the refusal is
the answer, and nothing after it is attempted. No page-closure writer calls `multiSet` or
`multiRemove` today, so this is the rule for whoever writes the first one rather than a change to
anyone's behaviour; both directions are pinned, including the refused first pair that stops the
rest.

* style(mobile): format the mirrored write path's census and journal writer

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

* test(mobile): count the note-first callers the mirror module says are held to one

Two gaps pullfrog found in the census. The last-visited key moved onto `persistMirrored` with no
row naming it, so removing its write path reddened nothing; and `mirrored-storage-keys.ts` says
the census holds `writeMirroredStorage` to one caller while nothing counted them.

Counted now, over every module under `mobile/src` rather than over a list of files a new caller
could sit outside of: a second one is either a writer that wants note-then-persist without the
store that earns it, or a page-reachable module that would note a refusal as an accepted write.

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

* docs(mobile): fold sendInit's doc onto the function it now describes

It still described an awaited post that answered whether the page received the frame, which
ruling 34 deleted: it fires the frame and answers nothing, a refused route sends nothing at all,
and a post the view would not take is one diagnostic and no further attempt.

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

* fix(mobile): let the page own a frame it received and could not handle

Ruling 34's addendum. On iOS the host's post is `callAsyncJavaScript`, which rejects when the
page's synchronous `onmessage` throws — with the document still mounted. The shell reads that as
a frame that never arrived, and it tracks nothing about posts, so nothing would ever send it
again. It is not a lost frame either: the page had it, one of its own listeners failed, and a
retry would fail the same way.

`receive` catches it and reports `inbound-listener-threw`, so the delivery is the channel's and
the handling is the page's. Nothing is swallowed and nothing is retried.

Two cases pinned the throw escaping and now pin it being reported: the ack that a listener bug
must not wedge, and the bootstrap stamp a tree that throws still leaves behind.

With that path closed, a post is refused only when no document holds the view, and the comments
on both halves of the route seam say so instead of naming a backoff that is stopped by then. The
repair is pinned rather than described: a tap that arrives while the view is gone is carried to
the next document's `ready`, because the held route advances on `hold` as well as on `send`.

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

* refactor(mobile): move the page's held session out of the client, which was at its cap

The listener catch put `bridge-rpc-client.ts` at 305 counted lines against a cap of 300, so this
splits rather than bumps.

The session is the one piece of the client with a lifecycle rather than a value: a second `init`
for the same session updates it in place, a different one replaces it and takes the requests and
streams of the session before it, and each case has its own listeners to fire in its own order.
The client keeps the frames and the ports; `bridge-client-shell-session.ts` keeps what they are
for, and the client's three members delegate to it.

The client measures 277 counted lines after the move. The session route's page closure is
unchanged at 4,330 / 988: the page reaches its client from the entry, not from the route module.

Jinwoo Hong e6de7a4bbe refactor(mobile): thread the scope through the terminal document and bundle the native script (OTA phase C, C7.5c) (#21878)
* test(mobile): pin the terminal WebView document byte for byte

The document is already pinned as a digest, which says whether the emitted
bytes moved and nothing about where. C7.1 moves the hand-written script inside
it into modules the web page can import and rebuilds the document from them,
and the claim that has to hold through every one of those commits is that the
native screen kept the document it had. A digest cannot be the instrument for
that: it fails as two hexadecimal strings.

So the document is also committed as itself. The fixture is generated by
`scripts/build-terminal-document-fixture.mjs`, never pasted, and the test
rebuilds the comparison through that script's own substitution rather than
restating it, so a fixture written by one rule and read by another cannot agree
with itself.

The generated xterm engine is stored as two placeholders. It is already covered
by the digest test, postinstall regenerates it from whatever xterm the lockfile
holds, and inlining it would put 612 KiB of vendored bytes into the file whose
job is to isolate hand-written changes. Two further cases keep that from
becoming a hole: the placeholders must each appear exactly once and the engine
must not appear at all, and the restored document must equal the real one.

Regenerating the fixture is a review event. It is only correct when the emitted
document was meant to change, and the diff in that commit is the evidence.

Red-first: flipping one character inside a comment in `write-queue.ts` fails
both identity cases with a one-line diff naming the comment, where the digest
test reports a hash.

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

* test(mobile): compare two terminal documents as programs, not as bytes

The C7.1 flip commit moves the document's 57 reassigned variables onto a scope
object, because a variable assigned across ES modules is a syntax error, and
every read and write of them gains a qualifier. The ruling asks that the review
of that commit be a test rather than a 515-line read. This is that test's
instrument.

It cannot be a byte comparison. Once the script's source is modules, `oxfmt`
owns its style, and the repository's style has no semicolons where the
hand-written document has one on nearly every line. A byte diff would therefore
be dominated by changes that are not the refactor, which is the opposite of
what the reviewer needs.

So the comparison is over tokens: semicolons are excluded for the same reason
they moved, comments never reach the stream, and one difference is allowed —
`name` becoming `<qualifier>.name`, three tokens for one — which it counts and
reports. It is stricter than "it still runs": a reordered statement, a changed
literal, a dropped operator, a renamed local and a qualifier under the wrong
object name all diverge, each reported with the token index and both sides.

Acorn carries `value` on its tokens but does not declare it, so the field is
read through a narrowing check rather than asserted onto the declared type.

Red-first, by mutation: dropping the qualifier-name check fails the case that
names it; removing the leftover-token check fails the dropped- and
added-statement cases; treating semicolons as significant fails the three cases
that depend on ignoring them. The acceptance case runs on the real 2,758-line
script rather than on a fixture, so the instrument is known to survive
everything the document actually contains.

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

* test(mobile): count each normalisation the move makes, separately

Measured while extracting the first group: the document's ES5 style is not a
style this repository's own rules permit. `curly` braces 279 brace-less
if/else/for/while bodies, `no-unused-vars` unbinds 38 catch clauses, and 446
`var` declarators become `const`, `let` or a scope field. Those rewrites land
before the qualifier is considered at all, so "the qualifier and nothing else"
was never reachable once the source is a linted module.

The comparison now allows exactly four classes and counts each on its own: a
reference that gained the qualifier, a declaration that moved onto the scope
object, a `var` that only changed keyword, a body that gained braces, and a
catch clause that lost its binding. Separate counters rather than a total,
because the flip commit pins each number and a total would let one class absorb
another — which is the drift the pin exists to catch. The two `var` classes
partition the 446, and the qualifier's 641 sites partition into references that
kept their declaration and declarations that moved.

Two ordering facts the cases pin. The catch rule is tried before the brace rule,
or the inserted-brace rule eats the `{` that follows `catch` and the streams
never resynchronise. A body braced at the very end leaves its closing brace
after the baseline has run out, so trailing closes are absorbed after the walk
rather than reported as a length difference.

Everything outside the four classes still refuses with the token index and both
sides: a changed literal, a dropped operator, a reordered pair, a renamed local,
a qualifier under another object's name, a brace opened and never closed, and a
brace closed where none was opened.

Red-first, by mutation: disabling the catch rule, disabling the trailing-brace
absorption, folding scope-field declarations into plain references, and not
counting brace insertions each fail exactly the case that covers them.

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

* refactor(mobile): make the mouse-report cell a module the page can import

The first of the twelve groups the document already names. `*-injected.ts` has
been splicing JS strings into the document for a while, and tests evaluate
those strings, so the one-source-two-consumers shape is already there; what is
missing is that a string cannot be imported by the web page, typechecked, or
linted. This turns one of them into a module and adds the generator that puts
it back into the document.

The generator is a transform, not a bundle: a bundler orders its output by the
dependency graph, and the document's order is part of what the equivalence test
holds fixed. Imports are dropped rather than resolved, because inside the
document every name is already in scope — that is what the single IIFE means —
and `document-externals.ts` declares the names whose groups have not moved yet
and emits nothing at all. esbuild prints an ESM module's exports as a trailing
block, so that block is dropped whole rather than by its keyword; leaving the
keyword behind would put a bare block statement in the document.

Both sides of the comparison now go through that same printer before being
read. Otherwise every choice the printer makes — semicolons, property
shorthand, quote style — reads as a difference in the program when it is a
difference in who typed it, and each would need its own rule. A script that
does not parse is reported as a refusal naming its side, not thrown.

`let` is contextual outside strict mode, so acorn reports it as a name and not
as a keyword; without that the var-to-let rewrite the linter performs would be
refused on every reassigned local.

The group's counts are pinned exactly: nine references gained the qualifier
(`term` seven times, `panX` and `panY` once each), nine locals became `const`
or `let`, thirteen one-statement `if` bodies gained braces, no declaration
moved onto the scope object and no catch clause lost a binding.

The document is untouched, so the byte pin from 3006d8dfdf is still green.

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

* refactor(mobile): make the query-reply gate a module the page can import

The second of the twelve groups, and the one that corrects the scope table's
membership rule.

`terminalDataRepliesEnabled` is written from four places, so the whole-script
census counted it among the 57 variables that cannot stay free across modules.
All four writes are in this group. Once the script is modules, a variable
written only inside the module that declares it is that module's own state, not
the document's, and it stays a `let` there. So the scope object holds what
crosses a module boundary, and the 57 is an upper bound rather than the answer;
the qualifier count the flip commit pins will be lower than the 641 measured
over the single scope, and by how much is a function of where the boundaries
fall.

Two references do cross here and are qualified: the write-queue generation this
group compares against, and the observer-disposal list it pushes onto.

Counts pinned: two qualified references, one `var` to `let`, two one-statement
`if` bodies braced, both `catch (e) {}` clauses unbound, no declaration moved.

The document is untouched, so the byte pin is still green.

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

* refactor(mobile): make reflow a module, and give the generator its own tests

The third group, and the defect it found: esbuild wraps a long import list
across lines, and the generator was skipping only the first of them, which left
the remaining names loose in the emitted script. The document did not parse, and
the equivalence check said so by name rather than throwing — which is what that
refusal path was added for. Both lists, import and export, are now skipped to
their closer instead of by their first line.

The generator's own tests cover what the per-group comparisons cannot say on
their own: an export is unmarked and indented into the document scope, a
one-line import is dropped, a wrapped import is dropped whole, the trailing
export block esbuild prints is dropped rather than left as a bare block
statement, and types are erased without touching the program.

Reflow's counts: eleven qualified references — the terminal ten times and the
settled row count once — six locals that became `const`, and the two early
returns braced. The row count is written from three groups, so unlike the
query-reply flag it is the document's state rather than one module's.

The document is untouched, so the byte pin is still green.

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

* refactor(mobile): make the keyboard-avoidance metrics a module

The fourth group, and the first that needed a non-null assertion.

`lineHasVisibleContent` reads the terminal's column count with no guard of its
own; the guard is in `computeContentBottomRow`, which is its only caller. Adding
a guard would change the program, and optional chaining would change what
happens when there is no terminal — the document throws there today. TypeScript
erases a non-null assertion, so the emitted script is unchanged and the
invariant is written down where the reader needs it.

Reflow now imports the metrics call from this module rather than declaring it an
external, which is the shape every group takes as its neighbours arrive.

Counts: fourteen qualified references, nine locals rebound, ten one-statement
bodies braced, and the two `catch (e) {}` clauses — the row scan and the
alternate-screen probe — unbound.

The scope table's rule is stated more precisely with it: a variable is this
module's own only when the group both declares and assigns it. While the rest of
the document is still strings, one the main slice declares stays shared even if
every use is in one group, because emitting a second declaration beside the one
the slice still carries would not be the same program.

The document is untouched, so the byte pin is still green.

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

* refactor(mobile): make WebGL loss recovery a module

The fifth group, and the first carrying a top-level statement rather than only
declarations: the visibility listener it registers. In the document that runs
when the IIFE reaches it; as a module it runs on import, which is the same
single registration.

The context-loss listener disposes the addon it is registered on, so it cannot
run before that addon exists, but the assignment is to a `let` a closure
captures and TypeScript will not carry the narrowing across it. A non-null
assertion, erased by the compiler, keeps the emitted script identical and puts
the invariant where the reader is.

Counts: twenty-three qualified references across the terminal, the addon, its
retry timer and the theme the host last sent; three locals rebound; twelve
one-statement bodies braced; five of the six catch clauses unbound, the sixth
keeping its binding because the attach failure reads the error into its
diagnostic.

The document is untouched, so the byte pin is still green.

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

* refactor(mobile): make indirect-pointer scroll a module, and count a fifth class

The sixth group found a rule the four classes do not cover, so I measured the
whole script rather than meeting them one at a time: linting all 2,757 lines as
a module trips `curly` 279 times and `no-unused-vars` 38, both already counted,
and then five further rules at 23 sites — `prefer-number-properties` 17,
`prefer-includes` 2, `no-useless-escape` 2, `prefer-exponentiation-operator` 1
and `no-unused-expressions` 1.

Seventeen of those 23 are one rewrite: a global numeric function moved onto
`Number`. It has the same token shape as the qualifier, so it is counted as its
own class rather than folded into anything, and only the four numeric globals
are admitted — anything else appearing under `Number` is refused, which a case
pins. Every site is already behind a `typeof … === 'number'` check or is parsing
a string, so the two forms are the same test.

The remaining six sites are each a different shape and too few to be worth
matching; they will surface as refusals in whichever group carries them, and I
will report each rather than widen this.

The scroll accumulator is the first declaration to move onto the scope: it is
declared in this group but a touch scroll in another slice resets it, so the
`var` becomes an assignment to the shared field and the class that exists for
exactly that counts one.

Counts: five qualified references, one declaration moved, four locals rebound,
eight bodies braced, one `Number` rewrite.

The document is untouched, so the byte pin is still green.

* refactor(mobile): extract the terminal surface-swap group into a module

The seventh named group. `surface` and the uncommitted terminal are read by
other slices, so both move onto the scope; the two committed handles and the

* feat(mobile): substitute build-time constants into the emitted document

The document's script text is not all hand-written: parts of it are template
literals interpolating real values, starting with the theme background. A
module cannot interpolate and still be the same program, so the generator now
derives an esbuild `define` from `document-constants.ts` and substitutes after
the import lines are dropped, when the names are free again. The page imports
the very same bindings, so there is one source either way.

The fixture script's TypeScript loader moves beside it rather than being
written twice.

* refactor(mobile): extract the terminal theme group into a module

The eighth named group, and the first parameterised one: its background
fallback comes from the mobile theme through `document-constants.ts`.

Two sites carry a line-scoped lint disable rather than the rewrite the rule
asks for: `indexOf(',') >= 0` and `Math.pow`. Both rewrites are outside every
normalisation class the equivalence instrument counts, so taking them would
change the program the native document carries, which is the one thing this
branch holds fixed. The reason is on the disable line.

Counts: qualified 12, scope declarations 0, rebindings 28, braced bodies 13,
unbound catches 0, number properties 9.

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

* refactor(mobile): extract the terminal path-tap group into a module

The ninth named group, and a pure query: it reads no shared state, so it has
no qualifier sites at all.

Two things this group forced. The generator now drops lint directive lines
before the transform, because a directive inside an expression makes esbuild
parenthesise that expression to keep the comment where it was, and those
parentheses are tokens the document does not have. And the two regexes keep
their `no-useless-escape` escapes behind a line-scoped disable, for the same
reason the theme group keeps `Math.pow`.

One name the document declares twice in one function stays `var`. Two
block-scoped declarations would be two bindings where the document has one,
and esbuild renames the inner one to say so.

Counts: qualified 0, scope declarations 0, rebindings 31, braced bodies 20,
unbound catches 0, number properties 2.

The tenth named group, and the heaviest reader of shared state: the selection,
its elements, its thresholds and both press origins are all declared by the
overlay slice, which is still document text, so all of them move onto the
scope with their declarations left where they are.

scope from the runtime slice; the gesture itself is declared here and never
read outside, so it stays a module local.

Counts: qualified 17, scope declarations 0, rebindings 22, braced bodies 27,
unbound catches 1, number properties 0.

* refactor(mobile): extract the terminal url-tap group into three modules

The twelfth and last named group, and the second parameterised one: both
candidate patterns and the length bound come through `document-constants.ts`.

Three modules rather than one. At 303 lines it was over the file cap, and the
document's own order interleaves the OSC 8 lookup with the file-URL parsing,
so the split follows that order and the group's text is the three emissions
joined. The test does the joining.

Note for a later lane: `terminal-webview-url-tap.ts` and
`terminal-file-url-tap.ts` already hold TypeScript twins of some of this,
written for the React Native side and not identical to what the document
carries. Collapsing the two is a behaviour change and does not belong in a
branch whose whole claim is that the document did not move.

Counts: qualified 10, scope declarations 0, rebindings 41, braced bodies 25,
unbound catches 6, number properties 4.

The script and the document end in the same slice, so the slice splits in two
at the point where the IIFE closes: the script half becomes a module, the
document half stays text. The byte pin proves the join is unchanged.

The second catch keeps its binding: it names the error and reports it.

Counts: qualified 1, scope declarations 0, rebindings 1, braced bodies 0,
unbound catches 1, number properties 0.

* refactor(mobile): give the document close its own slice file

The previous commit put two exports in one slice file, which the slice-count
guard reads as a mismatch: it derives the slice list from the composer's
imports and cross-checks it against the composed entries, one per file. Five
suites failed to load.

Splitting the file rather than the constant is the better shape anyway. The
file was called `message-bridge-and-document-close` because it carried two
concerns; now each has its own.

This slice interpolates the already-extracted keyboard-avoidance group between
its own two halves, so its text is three emissions joined in that order and
the test does the joining.

A sixth normalisation class, measured here rather than assumed: the printer
writes `{ name: name }` back as shorthand, and qualifying the value makes the
property name unavoidable again, so one baseline token faces four. It is
counted on its own like the others, with its own acceptance case in the
instrument's test, and every existing group's pin now carries a zero for it.

Counts: qualified 36, scope declarations 1, rebindings 12, braced bodies 12,
unbound catches 6, number properties 0, shorthand properties 4.

* refactor(mobile): extract the selection-state-and-eviction slice into a module

The slice that declares most of the shared selection state: every threshold,
every overlay element and the selection itself, twenty-two scope declarations
in one place. The eviction counter is declared and assigned only here, so it
stays a module local.

Counts: qualified 12, scope declarations 22, rebindings 2, braced bodies 3,
unbound catches 0, number properties 0, shorthand properties 0.

* refactor(mobile): extract the smooth-scroll and cell-geometry slice

Two modules, not one: the slice carries the normal-buffer smooth scroll and
then the cell-to-pixel geometry, and the split follows that order so the
group's text is the two emissions joined. Four names stop being externals and
become real imports.

Counts: qualified 39, scope declarations 0, rebindings 15, braced bodies 16,

* refactor(mobile): extract the terminal write-queue slice into a module

The slice also carries `disposeTermObservers` and `extractMouseModeScanTail`,
which belong to other concerns but sit here because emitted-document order
pins them here; four names stop being externals as a result.

The observer disposal keeps its guard-as-expression form behind a line-scoped
disable: the rewrite the rule asks for is outside every counted class.

* refactor(mobile): extract the terminal fit-scale slice into a module

The slice opens with the already-extracted theme group, so its text is two
emissions joined. Four more names stop being externals.

unbound catches 0, number properties 9, shorthand properties 0.

* refactor(mobile): extract the terminal init-and-write slice into a module

The slice opens with the already-extracted webgl-recovery group, so its text
is two emissions joined. init() resets almost every field the document shares,
which makes this the densest qualifier site in the script.

The caret options were interpolated from the theme module, so they join
`document-constants.ts` as four exports: a substitution is keyed by name, not
by property path.

One local the document declares and never reads keeps a line-scoped
`no-unused-vars` disable. Removing it would be a different program, which is
the one thing this branch does not do.

Counts: qualified 83, scope declarations 0, rebindings 11, braced bodies 18,
unbound catches 7, number properties 0, shorthand properties 0.

* refactor(mobile): extract the runtime-state and text-scaling slice

The document's declaration block, where almost everything it shares is
declared, with the query-reply and surface-swap groups interpolated inside it.
Three modules: the two declarations that come before the groups, the text
scaling, and the viewport transform with the scroll indicator. Seven more
names stop being externals.

Two things this slice forced.

The scope-declaration rule now counts each declarator of one `var`, because
`var panX = 0, panY = 0` becomes two assignments onto the scope. It has its
own acceptance case in the instrument's test.

The two halves are compared against their own text rather than as one joined
program. The declaration the slice opens with is shadowed by a parameter
inside one of the interpolated groups, and printing the baseline as one
program renames that parameter; qualifying the outer name removes the shadow,
so the rename has nothing to correspond to. Splitting the slice on the group
constants compares like with like, and those groups have their own tests.

Build-time constants are now substituted textually rather than through an
esbuild `define`: a `define` whose value is an object or an array is injected
as a helper binding instead of being inlined.

Counts, head: scope declarations 2. Tail: qualified 31, scope declarations 38,
rebindings 25, braced bodies 13, unbound catches 1.

* refactor(mobile): extract the mouse-report and scroll-routing slice

Two modules around the already-extracted mouse-report-cell group: the viewport
cell lookup that precedes it, and the mouse input encoding and scroll routing
that follow. Eight more names stop being externals, which leaves ten.

Counts: qualified 49, scope declarations 0, rebindings 49, braced bodies 42,

* refactor(mobile): extract the host-message-router slice into modules

Two modules after the already-extracted reflow group: the postMessage bridge
with the engine error reporting that rides on it, and the router itself.
`notify`, `handleMsg` and `reportEngineError` stop being externals, which
leaves seven.

The catch binding handed to the error reporter keeps a cast: a catch variable
is `unknown` under strict mode, and the reporter reads only `message` before
falling back to `String()`. The reason is on the line.

Counts: qualified 48, scope declarations 0, rebindings 20, braced bodies 12,

* refactor(mobile): extract the selection-overlay slice into modules

Two modules after the already-extracted path-tap and url-tap groups: the
selection range with the xterm mirror, and the overlay positioning with the
edge scroll. Six more names stop being externals, which leaves one.

Counts: qualified 77, scope declarations 0, rebindings 96, braced bodies 63,
unbound catches 9, number properties 6, shorthand properties 0.

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

* refactor(mobile): extract the surface-touch-gestures slice into modules

The last of the thirteen slices. Two modules after the three already-extracted
groups: the selection menu's buttons, and the touch gestures with the pinch
and the momentum scroll. `attachSurfaceEventHandlers` was the last external,
so `document-externals.ts` is gone: every name the document uses now resolves
to a module.

The instrument reads both sides strict. A loose script has to defend Annex B's
block-scoped function declarations, and the printer does that by hoisting a
`var` and renaming the function, so one side carried a rename the other could
not. Neither name escapes its block, so the two readings agree on behaviour
and only the strict one can be compared. It has its own acceptance case.

Counts: qualified 104, scope declarations 1, rebindings 69, braced bodies 57,
unbound catches 2, number properties 2, shorthand properties 0.

* refactor(mobile): extract the document's opening declarations into a module

The document shell carried the IIFE opener and the eight declarations inside
it, so it splits the way the message-bridge slice did: the shell keeps the
HTML and the opener, a new slice file holds the declarations, and the byte pin
proves the join is unchanged.

With this every line of the document's script has a module behind it.

Counts: qualified 3, scope declarations 8, rebindings 0, braced bodies 0,
unbound catches 0, number properties 0, shorthand properties 0.

* test(mobile): pin the whole document script against the modules

Every line of the script now has a module behind it, so the whole thing can be
compared at once. This is the review of the move, as one number per class:

  qualifier            609 references + 73 declarations = 682 sites
  var rebindings       373, the document's 446 declarators less those 73
  curly braces         279, the number measured before any of this started
  unbound catches      36 of 38; two name their error and report it
  Number properties    17, also measured up front
  shorthand properties 4, two SGR flags written twice each
  unshadowed names     7

A seventh class was needed and is counted like the others: a binding that
shadowed a document variable stops being a shadow once that variable moves
onto the scope, so the printer stops disambiguating it. It has its own
acceptance case.

The module order lives in one file that both this test and the generator read,
so neither can drift from the other.

* style(mobile): keep only the lint directives that do something

Seventeen of the disables were inert: `typescript/no-non-null-assertion` is
not enabled here, and a directive naming two rules on one line is not parsed
at all, so the one rule that did apply was being ignored too. The changed-code
quality gate reports an inert directive as a finding.

The two that matter are back, one rule per line: the guard-as-expression in
the observer disposal, and the local the document declares and never reads.

* feat(mobile): generate the terminal document from its modules

The WebView document is no longer a hand-written IIFE pasted into a template
string. `scripts/build-terminal-document-script.mjs` reads `document-scope.ts`
and the 36 modules under `src/terminal/document/` in document order, strips
their imports, exports and line-scoped lint directives, substitutes the
`document-constants.ts` exports textually, reprints each with esbuild and wraps
the result in one IIFE. `terminal-webview-html.ts` composes the shell, that
generated script and the close fragment. The artifact is gitignored and built by
postinstall, like the two engine artifacts.

The emitted document is token-equivalent to the old one under eight counted
normalisation classes, each pinned as an exact number in
`document/terminal-document-flip.test.ts` against the pre-flip text:

  qualifiedReferences     609
  scopeFieldDeclarations   73
  rebindings              373
  bracedBodies            279
  unboundCatches           36
  numberProperties         17
  shorthandProperties       4
  unshadowedNames           7

Any other difference fails with the token index and both sides. The second case
pins that the new document adds the scope object and nothing else.

Ruling 17: the behavioural tests now grep the generated document through
`XTERM_HTML`, never a module source, so every assertion still speaks about what
the WebView runs. Every assertion stays and the `expect` count per file is
unchanged: scroll-routing 95, text-zoom 59, engine 49, url-tap 33, reflow 22,
keyboard-avoidance 18, query-reply 14. One control per file was run by deleting
the module line the updated pattern guards; all seven red, and the tree restores
green.

Pattern changes, old -> new.

* refactor(mobile): delete the slice constants and injected fragments

The document is generated from its modules now, so the strings it used to be
pasted together from are dead. Deleted: the fourteen slice constants under
`terminal-webview-html/` (host-message-router, message-bridge,
mouse-mode-decset-scan, mouse-report-and-scroll-routing, runtime-constants,
runtime-state-and-text-scaling, selection-overlay, selection-state-and-eviction,
smooth-scroll-and-cell-geometry, surface-touch-gestures,
term-observers-and-mode-mirroring, terminal-fit-scale, terminal-init-and-write,
write-queue) and the eleven `*-injected.ts` files. `document-shell.ts`,
`document-close.ts` and `theme.ts` stay: the shell and close are still the
document's HTML, and `theme.ts` is where `document-constants.ts` reads the
palette from.

Ruling 17, second commit. Tests that asserted the extraction mechanism itself
went with it: they compared one module's emission against the slice text it was
extracted from, and the flip test now pins the whole document against the whole
pre-flip script with the same eight classes. Deleted, all under `document/`:
fit-scale, host-message-router, keyboard-avoidance-metrics, message-bridge,
mouse-click-drag, mouse-mode-decset-scan, mouse-report-and-scroll-routing,
mouse-report-cell, path-tap, query-reply, reflow, runtime-constants,
runtime-state, selection-overlay, selection-state-and-eviction,
smooth-scroll-and-cell-geometry, surface-swap, surface-touch-gestures,
tap-dispatch, term-observers, terminal-init, terminal-theme, webgl-recovery,
wheel-scroll. `document/url-tap.test.ts` stays: it pins against
`URL_TAP_WEBVIEW_JS`, which is neither a slice constant nor an injected file and
still has a consumer.

Tests that asserted behaviour through a deleted string now read the generated
document. `document/generated-document-region.test-support.ts` is the one way in:
`documentScopePreamble()` returns the scope object the document opens with, and
`generatedDocumentModule(name)` re-emits a module and refuses unless the document
carries that text verbatim, so an evaluated block is the WebView's own bytes. The
two local copies of the preamble in the engine and text-zoom tests were folded
into it.

Moved, with every assertion kept and the `expect` count per file unchanged:

The other eight files kept their patterns; only the text they read changed, from
a deleted constant to the document block. The harnesses that evaluate a block now
build the document's scope object instead of declaring the vars it replaced, and
hand the terminal in as `scope.term`.

Controls, one per file: the module line an updated pattern guards was removed,
the document rebuilt, and the test run. All red, and the tree restores green.

`document-scope.ts` docstrings named the slice each field belonged to; they name
the owning module now. Three module comments pointed at deleted injected files
and point at the modules instead. Neither changes the document: esbuild drops
comments, and the byte pin is unmoved.

* test(mobile): name the right number of counted classes

The flip test's title still said seven; the table it asserts has eight.

* fix(mobile): name the shape applyTerminalTheme writes through

The anti-slop gate refused `loadThemeApplier(term: object)` in the theme test.
`applyTerminalTheme` touches exactly two slots on the terminal it is handed, so
`terminal-theme.ts` now exports that shape as `TerminalDocumentThemeTarget` and
the test's parameter and both fixtures use it. The theme is optional on the way
in because `applyTerminalTheme` is what writes it.

No cast. The type is erased by the generator's transform, so the document is
unchanged and the flip test's class table and the byte pin both still hold.

Control: restoring the `object` parameter reproduces the finding at
terminal-webview-theme.test.ts:35:33 and the gate exits 1; with the named type
it exits 0.

* test(mobile): retire the flip pin, leaving the byte golden as the document's fence

`terminal-document-flip.test.ts` compared the emitted modules against
`terminal-document-pre-flip-script.txt`, the hand-written script as it stood before
C7.1, and held exactly while no module changed. That is the proof of the flip, not a
standing fence: the first lane that must change a module has to retire it or restate
its counted classes for a reason that has nothing to do with the move.

C7.5 is that lane — the document's host seams become scope fields so the page can set
them — so both go here, while the test is still green. The flip proof lives at
51ae7b1b03 ("test(mobile): name the right number of counted classes"), which is where
anyone reviewing the move should read it.

From here the standing pin is the whole-document byte golden,
`terminal-document-golden.txt`, checked by `terminal-document-identity.test.ts` and by
the payload-hash digest beside it. Regenerating it is a review event: the emitted diff
is listed old to new in the commit message and in the PR body, and a golden that moves
without a listed diff is a blocking finding.

* feat(mobile): give the terminal document's host seams a field on its scope

Ruling 19: on the page `window.ReactNativeWebView` is the *shell's* bridge, so a
terminal `notify` through it would post raw terminal JSON into the bridge's channel,
and there is no engine IIFE hanging `Terminal` and the two addons off `window` because
the page imports xterm. Four reads had to become seams:

  host-notify.ts      notify()             -> scope.postToHost
  viewport-transform  flog()               -> scope.postToHost
  terminal-init.ts    new Terminal(...)    -> scope.createTerminal
  terminal-init.ts    window.Unicode11Addon-> scope.createUnicode11Addon
  webgl-recovery.ts   window.WebglAddon    -> scope.createWebglAddon

Each default is the window read the site already did, still performed at call time and
not captured when the scope is built, so inside the WebView the program is the one it
was. `document-host-seams.ts` holds the four and is emitted ahead of the scope object,
because the scope's defaults are those functions and the factory runs as the script is
parsed. `document-terminal-shape.ts` takes the xterm-shape types out of the scope's
file, which the four fields pushed over the 300-line cap; document-scope re-exports
them, so no importer moves. The page's side of the seam lands in C7.5's later commits.

Two shapes kept faithful rather than tidied. The unicode11 addon is still built inside
the `try` it was built in, so a constructor that throws is still swallowed; and no
WebGL addon still returns false from `attachWebglAddon` without reaching the `catch`,
which is the DOM-renderer fallback rather than a failure.

Golden regenerated: terminal-document-golden.txt 105,446 -> 105,968 bytes, document
723,480 -> 724,002. 20 lines out, 36 in, all at the five sites above and nowhere else:

  + (new, top of the IIFE) function postToReactNativeWebView(message) { if (window.ReactNativeWebView) { window.ReactNativeWebView.postMessage(JSON.stringify(message)); } }
  + (new) function createEngineTerminal(options) { return new Terminal(options); }
  + (new) function createEngineUnicode11Addon() { return window.Unicode11Addon && window.Unicode11Addon.Unicode11Addon ? new window.Unicode11Addon.Unicode11Addon() : null; }
  + (new) function createEngineWebglAddon() { return window.WebglAddon && window.WebglAddon.WebglAddon ? new window.WebglAddon.WebglAddon() : null; }
  - "      pendingTerm: null"
  + "      pendingTerm: null," and four fields: postToHost: postToReactNativeWebView, createTerminal: createEngineTerminal, createUnicode11Addon: createEngineUnicode11Addon, createWebglAddon: createEngineWebglAddon
  - flog's nine lines "if (window.ReactNativeWebView) { window.ReactNativeWebView.postMessage(JSON.stringify({ type: "log", tag: "[fit]" + tag, payload })); }"
  + flog's five lines "scope.postToHost({ type: "log", tag: "[fit]" + tag, payload });"
  - "    if (!scope.term || !window.WebglAddon || !window.WebglAddon.WebglAddon) {"
  + "    if (!scope.term) {"
  - "      addon = new window.WebglAddon.WebglAddon();"
  + "      addon = scope.createWebglAddon();" then "      if (!addon) {" / "        return false;" / "      }"
  - "    scope.term = new Terminal({"
  + "    scope.term = scope.createTerminal({"
  - "    if (window.Unicode11Addon && window.Unicode11Addon.Unicode11Addon) {" / "      try {" / "        scope.term.loadAddon(new window.Unicode11Addon.Unicode11Addon());" / "      } catch {"
  + "    try {" / "      const unicodeAddon = scope.createUnicode11Addon();" / "      if (unicodeAddon) {" / "        scope.term.loadAddon(unicodeAddon);" / "    } catch {"
  - notify's three lines "if (window.ReactNativeWebView) { window.ReactNativeWebView.postMessage(JSON.stringify(msg)); }"
  + "    scope.postToHost(msg);"

Nothing else in the document moved: the emitted indentation, statement order and every
other literal are byte for byte what they were.

Two pinned readers follow the move. `terminal-webview-payload-hash.test.ts` takes the
new length and digest. `terminal-webview-text-zoom.test.ts` kept both WebGL assertions
and aimed them where the text now is: `window.WebglAddon.WebglAddon` and
`new window.WebglAddon.WebglAddon()` are asserted on the scope preamble rather than on
the recovery module, and the recovery module is asserted to call
`scope.createWebglAddon()`. `host-seams.test.ts` is the new pin: it builds a scope
before the globals exist to show the defaults read the window when they post, shows
each addon factory answering null when the engine has none, and drives a host message
in and a notify out with all four fields set, asserting the bridge is never touched.
Red before this commit at 6 of 7 cases.

* build(mobile): write the xterm stylesheet as its own generated artifact

The page mounts xterm itself, so it needs the engine's stylesheet and must never
resolve the engine string: 612 KiB of minified IIFE built to be injected as text into
a WebView document, unusable under the shell's `script-src 'self'` with no nested
frame to load one into, and the largest single module the session route's closure
would carry. Both lived in `terminal-webview-engine.generated.ts`, so one import of
the CSS pulled the string in behind it.

`build-terminal-webview-engine.mjs` now writes `terminal-webview-engine-css.generated.ts`
beside it from the same read of `@xterm/xterm/css/xterm.css`, with the same comment
strip and the same `http%3A//` scrub the no-external-URL gate wants. Gitignored beside
its neighbour and written by the same postinstall step, so a fresh tree gets both or
neither. `document-shell.ts` takes the CSS from the new module and the engine string
from the old one; `build-terminal-document-fixture.mjs` and the two tests that hold
both constants read them from their new homes.

The document did not move: `terminal-document-golden.txt` is byte for byte what the
last commit left, 105,968 bytes, and the payload digest is unchanged.

The fence is `config/scripts/mobile-web-terminal-engine-closure.test.mjs`. It walks
every module under `src/terminal/document/` as an entry point — the document is one
script whose modules reach each other by side effect, so no single one of them roots
a graph holding the rest — and asserts the engine string is in none of their closures,
with two modules named as the precondition that the walk resolved anything at all. The
native document's own closure is asserted to still hold both generated modules, so the
first case cannot pass by the CSS having gone missing. And the third case plants a
document module that imports the engine string in a scratch tree and shows the walk
reports it, which is what makes the absence above a measurement.

`mobileWebAppRouteClosure` is now a caller of `mobileWebAppEntryClosure`, which takes
the entry points and an optional working directory; the route closure's own two entry
points and its extensionless-specifier reason are unchanged.

* refactor(mobile): drop the dead URL-tap constant and two stale reflow guards

Round 1 fixes, all three folded here.

1. `URL_TAP_WEBVIEW_JS` is gone from terminal-webview-url-tap.ts, with
   `document/url-tap.test.ts` deleted alongside it. The document is generated
   from its modules now, so that constant was a second copy of the URL-tap group
   with no consumer but its own tests. terminal-webview-url-tap.test.ts's
   resolver harness reads the document's own text instead, the path-tap,
   url-tap, osc-link-tap and surface-tap modules in document order through
   `generatedDocumentModule`, which refuses unless the document carries each
   verbatim. Its 33 expects all stay. One mechanism-only assertion went with the
   file: `document/url-tap.test.ts`'s single `compareTerminalDocumentScripts`
   pin of the three emissions against the constant, which the flip test's
   whole-document pin already covers. The file's other exports stay.

   The deletion surfaced a third reader. terminal-webview-scroll-routing.test.ts
   concatenated terminal-webview-url-tap.ts into its `source`, and its
   `notify({ type: 'terminal-tap' });` assertion was matching the constant's
   single-quoted text, not the document. The read is dropped, since nothing else
   in that file needed it, and the assertion is the document's form:

     notify({ type: 'terminal-tap' });  ->  notify({ type: "terminal-tap" });

   Its 95 expects stay. Leaving the read in place would let a document assertion
   pass against a module source, which is the hazard this lane exists to remove.

2. terminal-webview-reflow.test.ts guarded a template placeholder that no longer
   exists, so it could not fail:

     expect(XTERM_HTML).not.toContain('TERMINAL_REFLOW_JS}')
       ->  expect(XTERM_HTML.split(reflowSource).length - 1).toBe(1)

   Same intent against the generated document: the reflow module's emitted text
   is in the document exactly once. The case is renamed to say so and the
   comment above it describes the generator, not the deleted template.

3. Same file, the routine assertion still passed as a substring of the qualified
   call; qualified as line 30 already was:

     term.resize(nextCols, nextRows);  ->  scope.term.resize(nextCols, nextRows);

   Its 22 expects stay.

Controls, each verified to have changed the file first, all red, tree green
after restore:

  osc-link-tap  return parsePathLineCol(value)        -> url-tap test, 3 failed
  surface-tap   notify({ type: 'terminal-tap' })      -> scroll-routing, 1 failed
  reflow        scope.term.resize(nextCols, nextRows) -> reflow test, 2 failed
  module order  'reflow' listed twice                 -> reflow test, expected 2 to be 1

* feat(mobile): mount the terminal document in the page instead of a WebView

`react-native-webview` has no web build that renders anything: measured, it paints the
line "React Native WebView does not support this platform" where the terminal was. So
the page mounts the document itself — xterm imported from `@xterm/xterm` with the
unicode11 and webgl addons, and the document's own modules imported in the order the
generator emits them — behind the identical `TerminalWebViewProps` and
`TerminalWebViewHandle`.

Written as one implementation, not two. `use-terminal-webview-controller.ts` is
everything `TerminalWebView.tsx` did that was not about `react-native-webview`: the
readiness handshake, the pending queue, the write coalescer, the notify dispatch and
the whole imperative handle. Its two arguments are the difference between the hosts —
a sink that takes one `TerminalWebViewCommand`, and whether a foreground return has to
re-prove the document with a ping. The native component posts across the bridge and
answers yes on iOS; the web component calls `handleMsg` and answers no, because its
document is the page's own modules and there is no second content process to lose. A
second copy of that file is the fork the series exists to avoid, since the handle is
the contract every consumer holds.

`terminal-webview-ready-promises.ts` carries the two promises the handle hands out,
`awaitReady` and `measureFitDimensions`, which the controller's length made a module.
`document-style.ts` and `document-markup.ts` carry the stylesheet and the elements out
of the document shell; the shell composes them and the golden is byte for byte
unchanged, 105,968 bytes. `terminal-webview-html.web.ts` answers those two and the
caret options and nothing else, so the page resolves no document string and no engine
string.

`terminal-web-document-mount.ts` is what the WebView's HTML used to be: it plants the
stylesheet and the markup, sets the four scope seams, and reaches the modules by one
dynamic import — they read their elements as they are parsed, so a static import would
hoist above the planting and leave every one of them holding null.
`page-document-modules.ts` is the order, `message-bridge` excluded per ruling 19
because on the page those `message` frames belong to the shell; its one non-bridge
duty, the window-resize refit, is re-armed by the mount.
`page-document-module-order.test.ts` holds that list against the generator's own,
so a sorted import list or a module added on one side cannot pass.

Two page-side degradations, both bounded and both stated. The document assigns
`window.onerror` as it is parsed, so while a terminal is mounted page errors reach its
reporter; the mount restores the previous handler on dispose. And a browser that
refuses a WebGL context gets the DOM renderer, which is the fallback `webgl-recovery`
already has for a context loss, with a `[fit]webgl-unavailable` notify saying so
rather than a silent halving of the drain rate.

`terminal-webview-consumer-census.test.ts` is the pin the substitution rests on: it
scans `src/session` and the terminal directory for an import of the component file by
name, of `terminal-webview-html`, of either generated engine module or of anything
under `document/`, finds none outside the component and its mount, and shows on
planted text that it would report each. `mobile-web-terminal-engine-closure.test.mjs`
gains the component's own closure: `TerminalWebView.web.tsx` and
`terminal-webview-html.web.ts` are in it, the engine string, the native HTML module
and `message-bridge` are not.

Four source greps follow the code into its new home, every assertion kept:
`terminal-write-coalescer-boundaries` reads the coalescer's four boundaries in the
controller, and reads the two lifecycle clears once in `resetReadiness` plus both
WebView callers in the component; `terminal-webview-reflow` and
`terminal-webview-scroll-routing` read the handle in the controller and the two timers
in the promises module (`measureResolveRef.current === finish` -> `measureResolve ===
finish`, `void p.finally` -> `void pending.finally`).

One behaviour was nearly lost and is pinned by an existing case: the native
foreground-recovery ping reads `Platform.OS` at the moment of recovery, not at render,
so the transport asks a predicate rather than carrying a boolean.

* test(config): render the page's terminal in a browser under the shell's policy

Everything below the contract is new on the page: xterm is an import rather than a
612 KiB string in a WebView document, the document's modules run in the page's own
realm, and the elements they read by id are planted by the component. No module test
settles whether that opens at all under `script-src 'self'` with neither
`unsafe-inline` nor `unsafe-eval`, or whether a real terminal byte stream reaches the
buffer intact.

Three cases in the C6 render harness, against the bundle built by the real builder and
served under the policy parsed out of the shell's own Kotlin constant.

The stream is built for the grid rather than committed: an SGR colour change per cell,
an erase-to-end and an absolute cursor position per row, run out past the host's own
48 KiB chunk. 49,302 bytes applied through `handle.write`. It is read back through the
document's own path — select all, then the Copy button the overlay carries — so the
oracle is the component's `onSelectionCopy` prop and not a private reach into xterm:
6,133 characters, both edge markers present, and no escape byte or SGR text left in
them, which is what says the parser consumed the stream instead of printing it.

The second case takes a fit through the handle, which on the page is a command in and
a notify back with no bridge between, and carries design §8's cheap half of the IME
question. It first pins something that changes where that probe can even point:
xterm's own textarea is inert by the document's design — `query-reply.ts` makes it
read-only, untabbable and `inputmode=none` so touch and hardware keys go to the
screen's input — so text entering a terminal on the page arrives at a `TextInput`, and
that is what is typed into. Chrome reports `insertText` with `isComposing` false for
each character, logged as `[c7.5][beforeinput]`. A composing IME on a real soft
keyboard is the device step and this does not claim to answer it.

CSP violations are counted with a `securitypolicyviolation` listener installed before
anything else runs, which is stricter than the console-error filter the other render
checks use — and the first thing it found was not the terminal's. The page entry
carries Zod, whose `new Function` probe is swallowed by its own catch, so
`script-src: eval` is refused once on any page route with no page error and no console
line. The first case is the control that names it, on a route that mounts a marker and
no terminal; the two terminal cases subtract it and report zero of their own. Zero
page errors and zero console errors besides.

No route serves this screen until C7.7, so the component is bundled through a scratch
route tree, naming it extensionlessly so the bundler resolves `TerminalWebView.web.tsx`
exactly as a real route would. That step retires when the session route is registered.

* refactor(mobile): retire the last module concatenator and guard the order list

Round 2 fixes, all five folded here.

1. Deleted terminal-webview-html-source.test-support.ts.
   `readTerminalWebViewHtmlSource()` had no consumers left once the behavioural
   tests moved to the generated document, and it was the last thing that built a
   document-shaped string by concatenating module sources — its filter admitted
   `.test-support.ts` files too, so it could have grown one. Confirmed by grep
   that the only occurrence of either name in the repository was its own
   declaration.

2. New document-module-order.test.ts asserts both directions: the non-test,
   non-test-support `.ts` files under `document/` are exactly
   `{document-scope} + TERMINAL_DOCUMENT_MODULE_ORDER + {document-constants}`,
   and no name is listed twice. `document-constants` is the one exception
   because it is never emitted: its exports are substituted into the modules
   that import them as literals, so the document carries its values without
   carrying the module. A module added here and forgotten there would be dead
   code that reads as live; a name left after its file goes makes the generator
   throw at build time rather than at review time.

3. terminal-document-flip.test.ts's docstring now carries the retirement policy
   from ruling 18: the test is the proof of the flip and holds only while no
   module changes, the first lane that must change one retires it together with
   `terminal-document-pre-flip-script.txt`, and the standing pin from then on is
   `terminal-document-identity.test.ts`, whose fixture regeneration is a review
   event. Comment only.

4. terminal-document-equivalence.test-support.ts said 57 reassigned variables
   and "Four classes and no others". It now says 73 declaration sites and eight
   classes, with each class's measured figure named. Two doc comments sat above
   the wrong declaration and were moved onto what they describe: the
   `NUMBER_GLOBALS` one down to that constant, and the printing one down to
   `significantTokens`, with `STRICT_DIRECTIVE` given its own line.

5. build-terminal-document-script.mjs substituted constants with
   `replaceAll(regexp, literal)`, where `$&`, `` $` ``, `$'` and `$n` in a
   constant's value are read as replacement patterns. The substitution is now
   `substituteDocumentConstants`, exported so it can be tested directly, and
   replaces with a function.

Controls, each verified to have changed its input first, all red, tree green
after restore:

  plant document/zz-planted-module.ts   -> order guard, "+ zz-planted-module"
  drop 'wheel-scroll' from the order    -> order guard, "+ wheel-scroll"
  revert to the string replacer         -> 4 failed, "a $& b" became "a marker b"

The `$n` case is deliberately absent from that table: the pattern has no capture
group, so `$1` is already literal under either form and a case for it could not
tell them apart.

The document did not move. The byte golden, the digest and the flip test's class
table are all unchanged.

* test(config): measure what the page terminal costs the session route's closure

The session route is not served on the page until C7.7, but the closure the bundler
would walk is the same one and the terminal is the largest thing in it. Measured
against this branch's base, `ota-c7-1-terminal-document` at 51ae7b1b03:

  modules         4316 -> 4363        (+47)
  local modules    927 ->  971        (+44)
  minified bytes   3,930,787 -> 3,883,532   (-47,255)

The route gets smaller. It sheds six modules — the native component, the 612 KiB
engine string, the 105 KiB generated document script, the HTML module and the shell
and close around it — all string literals of a program the page cannot run, and gains
fifty: the component, its mount, the stylesheet and markup modules, the two the
controller split made, and the document's own thirty-nine, with xterm and the two
addons behind them at 607,945 bytes minified ESM on their own. `document-terminal-shape.ts`
is not among them: it declares types and esbuild emits nothing for it.

The census pins the trade in both directions, because "the engine string is absent"
passes just as well on a closure that resolved nothing: the six shed modules are
asserted gone, the eight gained ones and the three xterm packages asserted present,
and the document asserted whole except `message-bridge`, which ruling 19 keeps off the
page. It also holds the 16 px seam where C7.2 found it — nine offenders, no unresolved
styles — since the terminal's modules joining this closure is exactly the change that
could add a tenth unread.

The page-closure families were run before and after on the full corpus, never a
filtered scenarios file. Both sides: 7 files, 879 tests, exit 0 — and those 879
include the four page-closure pins, which assert the verdict of every golden C1, C2,
C3 and C5 record, so an unchanged run is an unchanged verdict table rather than an
unmeasured one. Per family with `vitest -t "session.terminal"`, both sides 19 passed
and 773 skipped. No family moved, which is what an inert lane should show: this
branch changes no RPC, no opcode, no grant and nothing the recorder reads.

* fix(mobile): clear the changed-code gate findings this lane introduced

Eleven findings from `check-changed-code-quality.mjs` against the base, all in code
this lane added, none of them a behaviour change.

Two type assertions lost their directive to the formatter. The xterm `Terminal` cast
sits on the second line of a wrapped arrow body, so a directive above the assignment
aims at the wrong line; it moves onto the line the assertion is on. The WebGL addon
cast had no directive at all. Both keep the same `SAFETY:` rationale on one line,
which is the only shape oxlint reads.

Two more assertions in `host-seams.test.ts` are gone rather than annotated. The
terminal double's `element` is a getter over a local the double's own `open` writes,
and `withSeams` reads each field it is about to overwrite through
`getOwnPropertyDescriptor` instead of indexing the scope with a cast.

Then three `eslint-disable no-console` directives that disabled nothing, an
`oxlint-disable` for `react-hooks/exhaustive-deps` that the rule never fired on — the
reason it carried stays as a comment, since the dependency list is still deliberate —
and one duplicated `node:fs/promises` import.

* refactor(config): name the closure helper what main already named it

A trial merge against `origin/main` conflicts on this function: main grew the same
generalisation independently, as `mobileWebAppModuleClosure(entryModules)` with
`mobileWebAppRouteClosure` delegating to it and three callers in the page-closure
families census. This branch is based on `ota-c7-1-terminal-document` and so cannot
merge main, but it can stop being a second spelling of the same thing.

Taken over wholesale: main's name, its parameter, its extension stripping and its
comment, with `mobileWebAppRouteClosure` reduced to the one-line delegation main
already has. The only addition is an options bag carrying `absWorkingDir`, which the
engine-closure census needs to plant a module in a tree of its own and show the walk
would report it; the real measurements never pass it. What was a whole-function
conflict is now that one hunk.

The census case that measured the native document had named
`terminal-webview-html.ts` with its extension, which main's stripping does not allow.
It names `terminal-webview-html/document-shell` instead — the module that actually
reads both generated ones — which is the better probe anyway and needs no extension
to resolve, since it has no `.web` sibling.

`web-overrides.json` also conflicts and is left alone: both sides append entries to
one list and the resolution is mechanical.

* refactor(config): put the two closure helpers in main's order

The previous commit took main's name and signature but left the route closure below
the module closure, where this branch had written it. Git merged both orderings and
produced two copies of `mobileWebAppRouteClosure` on the merged tree, which oxlint
reports as a duplicated export — a red the trial merge found and neither side's own
lint could.

Same order as main now: the route closure and its docstring first, the module closure
under it. The trial merge is down to one hunk, the `absWorkingDir` parameter, and the
merged tree lints clean.

* test(mobile): make the flip comparator refuse what it was accepting

Round 2 items 6 and 7, both in the equivalence instrument.

6. `isPrinterDisambiguation` accepted any `name2` facing `name` without proving
   the two were the same binding, so an unrelated rename ending in a digit would
   have been counted rather than refused. It is replaced by `UNSHADOWED_RENAMES`,
   an explicit list of pre-flip name, generated name and declaring module. The
   whole script has one entry: `term2` -> `term` in `query-reply`, which is the
   `term` parameter of `attachTerminalQueryReplyBridge` and its six uses, seven
   sites in all. That is stated in the docstring rather than encoded as a second
   pin, since the flip test already pins the total.

7. Brace absorption treated every unexpected `{` as a linter-added body and
   absorbed any later `}` while one was outstanding, so a bare block anywhere
   would have been swallowed. `isBraceableHeadBody` now requires the open to be
   the body of `if`, `for`, `while`, `else` or `do` — walking a `)` back to its
   `(` and reading the keyword before it — and `matchingCloseIndex` records the
   index the close must appear at, so the absorbed `}` is that body's own.

   That check had to move ahead of the equality check. Wherever a braced body
   ends a block, the baseline's next token is a `}` as well, so pairing them
   would consume the wrong one and leave the counts right for the wrong reason.

Both refusals are tested over snippets:

  function f() { return value2; }  vs  return value;
    -> token 6: expected name value2, generated name value
  let value = 1; use(value);       vs  { let value = 1; } use(value);
    -> token 0: expected name let, generated {

and the braceable heads are tested one by one, `if`, `for`, `while`,
`if`/`else` and `do`, so the new rule is shown to accept every shape the `curly`
rule produces and not only the one the document happens to exercise.

Controls: restoring the shape rule fails the first refusal case and nothing
else; restoring the accept-any-brace rule fails the second and nothing else.

The eight counts did not move: 609, 73, 373, 279, 36, 17, 4, 7.

Splitting out `terminal-document-tokens.test-support.ts` is not cosmetic. The
tightened rules put the file over the 300-line cap, and a `max-lines` disable is
forbidden, so the token reader moved to its own module: that side answers what a
script says, and says nothing about which differences between two of them are
allowed.

* docs(config): take main's docstrings for the two closure helpers

The order matched but the prose did not, so the trial merge still conflicted on the
whole block. Both docstrings are now main's own text, with one sentence trimmed: main
names `MobileBrowserPane` as the first component with a pin of its own, which is C6's
fact and not one this branch can assert.

What remains between this branch and main in this file is the `absWorkingDir`
parameter, which is what the engine-closure census plants a module with.

* fix(mobile): write the page terminal's notify sink in an effect, not during render

React Doctor's one error on this branch, and a real one: `receiveRef.current = receive`
ran during render. React may replay or discard render work, so a mutation made there
can leak from UI that never commits — and this ref is read from a callback the mounted
document keeps, which outlives the render that installed it.

Moved into its own effect, declared above the mount effect so the first read already
sees a sink. `check-react-doctor-changed.mjs` goes from exit 1 to exit 0.

Found late because the first run of that gate was read through `| tail`, which reports
the pipeline's last command rather than the gate's own exit code.

* test(mobile): teach C7.1's order guard the three modules this lane added

The guard C7.1 landed says the document directory and the order list name the same
modules. On this branch three files are in that directory and not in that list, so it
was red on the merge — which is the guard working, and the fix is to name each of them
with its reason rather than to loosen the scan.

  document-host-seams    emitted, but ahead of the scope rather than inside the order
                         list, because the scope's defaults are its four functions and
                         the factory runs as the script is parsed
  document-terminal-shape  types only; esbuild emits nothing and an empty emission
                         would add a blank line to the document
  page-document-modules  the page's entry, not the WebView's, holding the same order
                         for a host that has no generator to splice them

Named one by one, not filtered by a pattern, so a fourth cannot join them by looking
similar. A third case asserts the seams module is neither in the order list nor the
scope module, which is the ordering the first two cannot see.

Red before this commit: C7.1's version of the file on this tree reports
`document-host-seams` and the other two as directory modules the list does not name.

* test(config): re-measure the session closure against the merged C7.1 base

Same module counts — 4316 -> 4363 and 927 -> 971 local — but the minified figure moved
from -47,255 to -55,561, and the 8,306-byte difference is C7.1's rather than this
lane's. Its round-1 fold deleted `URL_TAP_WEBVIEW_JS` from `terminal-webview-url-tap.ts`,
a module that enters this closure only once the page's component reaches it, so the
saving shows on the after side and cannot show on the base. Both readings are recorded
with the commit each was taken against, because a number with one base named and
another used is the kind of thing a reviewer cannot check.

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

* test(mobile): retire the flip comparator with the pin it was built for

The token comparator had exactly two consumers and neither survives. `document/url-tap.test.ts`
went in C7.1's own round-1 fold at 8da7680c9b, and `terminal-document-flip.test.ts`
went in this lane's first commit under ruling 18, because the flip pin holds only
while no module changes and C7.5 is the lane that changes them. What was left was a
tool, its token reader and a test of the tool, answering to nothing.

So `terminal-document-equivalence.test-support.ts`, the
`terminal-document-tokens.test-support.ts` C7.1 split out of it, and
`terminal-document-equivalence.test.ts` all go. That closes round 3's two LOW notes on
the comparator — bounding an absorbed body to one statement, and refusing a bare block
as `use();` against `{ use(); }` — since there is no comparator left to tighten. The
standing pin on the document is the whole-document byte golden, which is a stronger
claim than token equivalence ever was: it admits no normalisation at all.

`document-module-order.test.ts` gains the case its exception list was asserting in
prose. `document-terminal-shape` is not in the order list because esbuild erases a
module of type declarations to the empty string, and emitting it would put a blank
line in the document rather than a program; that emission is now measured and pinned
as `''`. If the module ever declares a value the case goes red and the module belongs
in the order list with its own line in the golden diff.

* feat(mobile): make the document's error reporter the sixth host seam

Ruling 19 reaches `window.onerror`. The document assigned it as it was parsed, which
inside the WebView is taking nothing from anyone — that document owns its page — and
on the page is a guest displacing whatever the host installed. Restoring it on dispose
was a patch over the takeover, not an answer to it: while a terminal was mounted, every
page error still went to the terminal's reporter.

So `scope.installErrorReporter` joins the five, with today's assignment as its default.
`host-notify` hands it the same handler it always installed, and the WebView's document
is the program it was.

The page supplies its own: an `error` listener that adapts the event to the reporter's
arguments, added on mount and removed on dispose, and `window.onerror` is never
written. This one seam is *called* as the modules are parsed rather than later, so the
mount now reaches `document-scope` on its own first and sets every field before a
single document module runs — which is also the safer order for the other five.

Golden regenerated: 105,968 -> 106,116 bytes, document 724,002 -> 724,150. Three lines
out, seven in, and nowhere else:

  + (new, beside the other defaults) function installWindowErrorReporter(report) { window.onerror = report; }
  - "      createWebglAddon: createEngineWebglAddon"
  + "      createWebglAddon: createEngineWebglAddon," and "      installErrorReporter: installWindowErrorReporter"
  - "  window.onerror = function(msg, source, line, column, err) {"
  + "  scope.installErrorReporter(function(msg, source, line, column, err) {"
  - "  };"
  + "  });"

`terminal-webview-payload-hash.test.ts` takes the new length and digest.

Pinned on both sides. `host-seams.test.ts` gains the default taking `window.onerror`
and a host that installs its reporter elsewhere leaving it null. The render check adds
a browser case: `window.onerror` is null before the mount, null after it, and null
after the component unmounts — with a real uncaught error thrown in between and
asserted to reach `onEngineError`, so the first reading cannot pass on a terminal that
had simply stopped reporting, and a second error after dispose asserted to reach
nothing. Red with the mount's override removed: `expected undefined to be null`.

* test(config): empty the session closure's react-native-webview list

C7.6's census on main names the terminal as the last consumer and says whose work it
is: "The terminal is the third and is C7.5's, which drops the engine string and mounts
xterm in the document". This is that lane, so the list it left is now empty and the
session closure reaches `react-native-webview` from nothing at all.

Emptying a list weakens the case that reads it, because an empty result is also what a
scan that read no file reports, so two things change with it. The main case gains its
preconditions: the walk read a closure of more than 500 local modules, and it read the
three web siblings whose native halves are exactly the modules that would have
imported the package. And the control stops walking the list — with the list empty that
compared nothing against nothing — and walks the three native files instead, which do
import it, alongside the three web siblings, which do not.

`TerminalWebView.web.tsx` joins the answered list, so the case that the builder
resolves a web sibling rather than its native file now covers all three.

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

* test(config): pin the onerror seam against a handler the page actually owns

The case read `null` before the mount, while mounted and after dispose. That is true
but weak: a terminal that assigned `null` over a real handler would pass it, which is
exactly the takeover ruling 19 forbids.

So the page now installs a handler of its own in an init script, before the bundle
loads, and the assertion is identity — `window.onerror === globalThis.__orcaSentinel`,
compared inside the page because a function does not survive `evaluate` — at all three
points. Between them an uncaught error is thrown and both reporters are asserted to
see it: the page keeps the handler it installed, and the terminal's own listener still
works, so the readings cannot pass on a terminal that had simply stopped reporting.
After dispose a second error reaches the page's handler and not the terminal's, which
is what taking the listener off has to mean.

The `null` reading stays as its own case, because the other half matters too: on a page
that installed nothing the terminal must not leave a handler behind for the next
consumer to find.

Both go red with the mount's `installErrorReporter` override removed — `expected false
to be true` and `expected undefined to be null`.

* fix(mobile): start the terminal document per mount (ruling 20)

Round 1's blocking finding: ES module bodies run once per page, so the page's
second mount re-imported nothing and inherited the first mount's elements,
listeners and error reporter. Measured after a remount: zero .xterm nodes in
the live DOM, no selection overlay, nothing reaching onEngineError, and
onWebReady still firing.

Ruling 20: no emitted module does work as it is parsed. Every top-level effect
moved into an exported per-module start function — 86 statements across 14
modules, plus three parse-time captures whose declarations became typed lets.
The generator emits one call sequence in module order at the foot of the
document, so the native script still runs them once at parse; the page runs the
same sequence per mount and dispose undoes the three that outlive the host
element (tap-dispatch, webgl-recovery, host-notify).

installErrorReporter now hands back its own undo, so it stays five seams at six
document sites rather than growing a sixth.

M2: a failed document chunk was an unhandled rejection with no engine error.
It now goes down the document's own reporting path, so the overlay names the
cause instead of the 15s readiness watchdog. Pinned by refusing that chunk at
the wire in the render check.

L3: the seam count now reads five fields / six sites / three files everywhere.
L4: three unrelated web-overrides entries keep main's escaping.

* test(mobile): read the parse-time census tree without assertions

The changed-code gate refuses type assertions. The walker reached node fields
through `as Record<string, unknown>`; it now reads them with Object.entries,
which is checked and says the same thing.

* fix(mobile): move the document's state onto the scope (ruling 21)

Round 2's blocking finding, and ruling 20's second half: moving parse-time
effects out of the module bodies left the state behind. Nine module-level
bindings survived a mount, so the second terminal inherited a spent non-fatal
error budget (reporting nothing however it failed), the first terminal as its
committed surface (disposing it twice), and the first mount's momentum loop.

Every mutable binding now lives on the scope, and the scope carries one reset
the start sequence calls first: native once at parse, the page once per mount.
Moved, by module: query-reply 1, surface-swap 3, text-scaling 2, fit-scale 1,
host-notify 2, selection-state-and-eviction 1, mouse-click-drag 1,
tap-dispatch 1, surface-touch-gestures 1 — thirteen fields, two of them the
objects tap-dispatch and surface-touch-gestures used to own outright.

Because the reset is now the one initialiser, the start functions keep only
what it cannot do: element reads, listener installs and the reporter install.
Four start functions emptied and went; terminal-handle held nothing else and
is deleted from the order list. The scope type splits into state and host
seams, because a reset must restore the first and never the second.

Every stop function cancels what its module scheduled. Timers go back through
the handles the scope already held; frames go through the scope's own
scheduleDocumentFrame, so dispose can take back the ones no module tracks by
id. terminalGeneration and fitRetryToken carry forward across a reset, because
a stale callback tests itself against them and a reset to zero would make the
old number match again.

L2: the seams-before-scope case asserts the order in the emitted document, not
just non-membership. L3: the style docstring says what is true — one scope per
page, so mount refuses a second live document and gives the page back when a
mount fails.

* fix(mobile): refuse frames from a stopped document

The frame case went red under full-suite load: tearing the terminal down runs
the engine's own disposal, which calls back into these modules, and a frame
asked for on the way out was owed by nobody because the cancel had already run.
A stopped document now asks for no frames at all, so the ordering inside
dispose stops mattering.

The render case is also rewritten around the work that survives a loaded
machine. It gives the terminal a scrollback and sends one wheel, which reveals
the scroll indicator and arms the 550 ms timer to hide it again, and the
boundary between the two mounts is drawn when the first terminal leaves the
page rather than when the component is told to go — React unmounts on its own
schedule, and a callback that runs while the first terminal is still up is not
a leak. The precondition counts what the document scheduled under the first
mount, so an empty leak list cannot mean the wheel reached nothing.

Verified both ways at this head: red with stopViewportTransform and
cancelDocumentFrames removed, green with them, and green in the whole
config/scripts suite.

* fix(mobile): style only what the page mount owns

CodeRabbit on document-style.ts:16. The mount appended the document's whole
stylesheet to the page head, so its `*`, `html` and `body` rules restyled every
screen the shell can show and went on doing it after unmount. Ruling 19's
shape: the native document owns its page and keeps the sheet as it is; the page
mount may style only what it owns.

The sheet splits into TERMINAL_DOCUMENT_ROOT_STYLE and
TERMINAL_DOCUMENT_ELEMENT_STYLE, composed in the same order, so the emitted
document does not move for the split - verified byte-identical before the seam
below. The page injects the element half only, with every selector held under
the host's own class, and xterm's sheet goes through the same rewrite. The
rewrite refuses an at-rule rather than passing its inner selectors through
unscoped.

A second leak of the same kind was in the same measurement: applyTerminalTheme
wrote the terminal background straight onto `html` and `body`. That is a sixth
seam - six fields at seven document sites now. Its default does exactly the two
writes it did; the page paints the host element instead. Emitted lines, old to
new: `paintWindowDocumentBackground` added beside the other defaults (3 lines);
`paintDocumentBackground: paintWindowDocumentBackground` added to the seam
factory (1 line); in applyTerminalTheme, the two `document...style.background`
writes become one `scope.paintDocumentBackground(background)`.

Leaving the sheet in the head after unmount is kept, and is now defensible: the
host drops the class on dispose, so every rule in it matches nothing until the
next mount.

The render check gains a case comparing `body` and `html` computed styles,
while mounted and after dispose, against a page of the same application with no
terminal on it, and asserting no rule of the injected sheet matches an element
outside the host. Verified red both ways at this head: unscoped sheet moves
`background-color` and `box-sizing`, and the inline theme write moves
`background-color`.

* test(mobile): give the page mount's rules and frames their own oracles

Round 3 blocks on evidence, not on shipped behaviour. Each item:

H1. The scoping had no positive oracle: dropping the host class, or injecting
an empty xterm sheet, left the render check green, because every assertion was
about rules not escaping. The containment case now also reads four things off
the live elements under the host — xterm's own `position: relative`, the
viewport's `overflow-y: hidden`, that the viewport reserves no scrollbar width,
and the overlay's `position: fixed`. Red both ways: no host class reds all
four, an empty engine sheet reds the first.

H3. `cancelDocumentFrames` had no witness: the only leak the timer case could
see was the 550 ms hide timer, which its own module's stop cancels. There is
now a case whose witness is a frame taken through `scheduleDocumentFrame` —
the fit retry loop, with the surface hidden so the fit never commits and one
frame is always owed at dispose — and it reds when only `cancelDocumentFrames`
is removed. A unit covers the registry itself: a frame is held until it runs,
a cancel takes back every pending one and then refuses to schedule, and a reset
re-enables it.

The two scheduling cases now assert on their own witness kind, so neither can
stand in for the other, and the recorder judges a leak by whether the
`#terminal-container` that was on the page at schedule time is still in the
document — React unmounts on its own schedule, and a callback that runs while
the first terminal is still up is not a leak. The timer witness moved from the
scroll-indicator timer to the long-press timer, because the first needed a
drained scrollback and raced the engine under load; its precondition caught
that rather than passing.

L1. The two seam docstrings each sit on their own function.
L2. The parse-time census plants an element-read initialiser, which the
statement filter cannot see, and an inert object literal, which a reader that
flagged every initialiser would wrongly report.
L3. Dispose disposes `scope.committedTerm` as well as `scope.term`: a swap that
never committed leaves two terminals and only one was reached. Deduplicated,
because they are the same object whenever no swap is open, and pinned both ways.
L5. `document-style-scoping.ts` joins GAINED_OUTSIDE_THE_DOCUMENT.

* fix(mobile): make the page document's dispose idempotent and owner-checked

CodeRabbit on terminal-web-document-mount.ts:180. Dispose was neither. A
handle outlives what it built - the component keeps one in a ref and React can
run a cleanup after a later mount has started - and everything dispose touches
is shared: the scope, the module sequences, window.__engineErrors. So a second
call, or a call from a handle whose document had already been replaced, tore
down the terminal that was on the screen and handed the page away while it was
still in use.

Each mount now carries a token, and dispose acts only when that token is still
the live one. A token rather than the host element or its class: two mounts can
be handed the same element, because the page remounts into a host React has
reused, so an element is not an identity and the class says only that some
document is using the host. The failed-mount path releases the page under the
same check.

Pinned both ways, red with the check removed: disposing twice leaves a terminal
put back after the first teardown alone, and a stale handle disposed after a
second document mounted changes nothing - the live markup stays, its terminal
is not disposed, and the page is still refused to a third mount.

Golden unchanged at 108,329 bytes; payload and hash unchanged.

* fix(mobile): let a pending page mount be disposed before its import lands

Round 4 on #21809.

H1. The mount claimed the page before its dynamic import and handed back a
promise, so a component cleanup that ran while the chunk was still in flight had
nothing to dispose: the claim outlived the mount it was made for, and Reload —
the recovery ruling 20 names — was refused as a second document. The claim, the
markup and the handle are now made synchronously, `ready` settles on its own,
and a mount disposed while its import was in flight releases without starting
anything. Pinned in the render check by holding the document chunk 20 s past the
15 s readiness watchdog, clicking Reload and waiting for the second mount to
become live; red at that wait before the change.

M1. The frame case's precondition asserted that a frame had been asked for while
the document owned the page, not that one was owed when it was disposed. The fit
retry commits on its first attempt whenever the grid still measures, so a dispose
between two refits owed nothing and agreed with an empty leak list for exactly
the reason under test — one run in five. The refit and the unmount now share one
discrete click, which React flushes before the event returns, and a mutation
observer reads the registry at the instant the host is emptied. Five red runs
without `cancelDocumentFrames`, all on the leak and none on the precondition,
and five green with it.

M2. Two mounts handed the same element, which is what the token is for: the
other six cases use a different element each, so a host comparison passes all of
them.

L1. A throw inside the start sequence released the token but ran no stop, leaving
the host-notify error listener installed until the next reset nulled its undo.
The sequence now unwinds the starts that completed, in reverse, before it
rethrows.

L2. A render case comparing the window and document listeners the page holds
with no terminal on it, before and after a mount, so a stop that forgets one is
a failure rather than a second copy per terminal ever shown.

L4. Separated the stacked docstrings in the parse-time-effects census.

The render check's bundle, server, browser and page helpers move to their own
fixture module: the cases are what is under review and the scratch route tree is
not, and the file was 16 code lines under its cap.

* test(config): count the page document's leaked frames from dispose, not from detach

CI's addendum to round 4's M1: the frame case failed with the fix present,
`expected [ Array(1) ] to deeply equal []`, on a slower runner.

What scheduled it: `applyFitScale`, through `scheduleDocumentFrame` like every
other frame the document asks for — the document has no other rAF call site. It
is not an escape from the registry, so the registry is not what changes here.

Why it was counted: React unmounts in two steps. The mutation phase detaches the
host, and the passive cleanup that calls `dispose` runs after it — about 1 ms
later here, 20 to 35 ms later with the CPU throttled 20x, which is the runner
shape this failed on. A frame served in that gap runs with a detached container
while the document is still live and has not been asked to stop, and nothing
could have taken it back: `cancelDocumentFrames` had not been called yet. The
oracle judged by the captured container's connectedness, so it read the gap as a
leak. It now counts only what runs after the last statement of `dispose`, which
is the class coming off the host, observed on the element because React may have
detached it already.

The same reading fixes the other direction. The precondition is read at that
same moment, and the witness is a refit re-armed from a frame of the test's own,
so the document is owed a frame at the end of every frame the browser serves and
a dispose cannot land where nothing is owed. The single refit the case used
before bought one frame, and the retry loop commits on its first attempt
whenever the grid still measures.

Evidence: with the boundary removed the case reproduces CI's `Array(1)` in two
runs of three unthrottled, and in five of five with the CPU throttled 20x, where
the detach-to-dispose gap measures 20 to 35 ms; with it, five green runs; with
`cancelDocumentFrames` removed, five red runs, all on the leak read and none on
the precondition.

* fix(mobile): stop a page mount that lost its claim before it writes the scope

Round 5 on #21809.

F1 (blocking). `buildTerminalWebDocument` had no token, so after its `await
import(...)` the whole body ran whatever had happened in the meantime: it
overwrote the six seams, called `startPageDocumentModules` and added the resize
listener, and only then did the caller's `.then` read the claim and throw the
result away. Everything after that await is shared — the seams are fields on a
module-singleton scope, and the start sequence resets that scope and installs
the document's listeners — so a mount disposed while its chunk was in flight was
writing over a mount that owns the page. The claim is now re-read the instant
the import lands, before any of it, and the build returns null.

`ready` for such a mount resolves rather than rejecting. Nothing failed: the
caller asked for the terminal and then asked for it to go away, and the chunk
arriving afterwards is not something for the error overlay to name. Before this
it rejected with a TypeError from `startSelectionMenuButtons` reaching for an
emptied host.

F2. The rejection handler called `release()` unconditionally, emptying a host the
mount may no longer own. It now releases only when the page is still its own.

Pins, both red first. In happy-dom: mount, dispose, then await ready — no
listener, timer or frame added while it resolves, the six seams unchanged,
`terminalGeneration` unmoved because the start sequence never ran, and the page
free for the next mount. Without the fix that case rejects with the
`startSelectionMenuButtons` TypeError. In the browser, the Reload-while-in-flight
case now reads the page's listeners with no terminal on it and compares them
against a page that mounted once and disposed once; without the fix the
abandoned mount leaves `window error` and `window resize` behind, because the
second mount's scope reset nulls the first mount's reporter undo.

The listener snapshot helper is shared with the mount-and-dispose case rather
than written twice.

* fix(config): give the render fixture's server and scratch tree back when it cannot start

CodeRabbit on the render fixture, plus its note on `release`.

The fixture. `chromium.launch` is the last step of the setup and the one that
fails in practice — no Chromium on the machine, an
`ORCA_MOBILE_WEB_RENDER_BROWSER` pointing nowhere — and by then the bundle
server is listening and the scratch tree is on disk. Rejecting there left the
caller without a handle, so `afterAll` had nothing to close and both stayed
allocated; the listening socket is the one that bites, because an open server
handle keeps the vitest worker alive after its last test has reported. The setup
after `mkdtemp` is now wrapped, gives back whatever it managed to take, and
rethrows the original error rather than anything the cleanup raised. The normal
close path awaits the server-close callback instead of firing it.

`release` in the page mount. The ownership check covered the claim but not the
two lines that make the terminal disappear, so a release that skipped the claim
would still empty the host and drop its class. The check now guards the whole
function, and round 5's caller-side check is gone as a duplicate of it: one rule,
inside the thing it governs. Both existing callers are unchanged in behaviour —
the synchronous planting catch always owns the page, and the rejection handler
was already guarded.

Pinned red first. The new case points the launch at an executable that is not
there, then asks the port the fixture actually served on for a connection and
reads the scratch directories in the temp dir. Without the rollback the port
still accepts and the scratch tree is still there; with it, neither. The port is
recorded by wrapping the real `createBundleServer` rather than standing a double
in front of it, and the case asserts a server was created at all, or the refusal
would mean nothing.

Two oracles were discarded on the way. `rejects.toThrow()` with no argument
passes for a build that broke for its own reason, so the rejection is matched by
message. `process.getActiveResourcesInfo()` reports `TCPServerWrap`, not
`TCPSERVERWRAP`, so a count filtered on the upper-case spelling was zero in both
arms and agreed with everything; it also still lists the handle at the moment
the close callback runs.

* test(config): read the render fixture's rollback in a temp root of its own

Two defects in the case I committed in cb1833e675, both found by running it.

The anti-slop gate refuses module mocking, and it is right to: the case recorded
the served port by mocking the harness module around the real
`createBundleServer`. Gone, with no disable.

Its replacement read the shared temp directory for the fixture's scratch prefix,
which the render check next door writes to from a worker of its own. So the case
watched that tree appear and be swept up mid-run and called it a change: one red
in four alone, and red in the full suite, where the two run together. `TMPDIR`
now points at a directory this worker made, so the fixture's scratch tree lands
somewhere nothing else writes and what is left in there afterwards was left by
the setup under test. The failed launch also leaves Playwright artifacts and a
browser profile in there, which are Playwright's to clean, so the reading is
filtered to the name the fixture gives its own trees.

The listening-socket half is unchanged and was right: spelled `TCPServerWrap` as
Node spells it, and read a tick after the close callback, because the handle is
still listed while that callback runs.

Both halves now fail on their own without the thing they measure: with no
rollback at all the socket count is one above its baseline, twice out of twice;
with the rollback but no `rm`, the scratch tree is still there. Three green runs
with both.

* fix(mobile): hand the started document to the mount in the turn that started it

Round 6's two LOW items, and the pins for the owner-checked release.

LOW 1. `started` was assigned in the `.then` after the build, a microtask later
than the start sequence and the resize listener it installs. A dispose in that
window found nothing started, skipped the teardown and released the page with the
document still running on it. The build now takes an `adopt` callback and calls it
as its last statement, inside the guarded region, so whoever has to undo the
start is holding it before that turn ends. Pinned by queuing the dispose behind
the document import the build awaits, which lands in exactly that window: without
the change the started document's resize listener survives the dispose, five red
runs out of five.

The owner-checked release, which landed in 8b37221b57 without a pin of its own.
The one path that reaches a mount's cleanup holding someone else's page is a
rejected import: everywhere else the build re-reads the claim after its await and
stops, but a rejection never gets that far. So the pin drives that — the chunk
fails for the first mount only, the mount is disposed while pending, a second one
is built into the same element as Reload does, and then the first rejection
arrives. Without the guard inside `release` it empties the live mount's host:
three red runs out of three, on the markup. It also disposes the abandoned handle
a second time afterwards and asserts nothing moves, which is LOW 2's missing pin
for round 5's F2.

That case is its own file because the import has to fail before the mount module
loads, and the mocking the failure needs is only permitted in `.test.ts` — the
anti-slop override does not cover `.test.mjs`, which is what refused the port
recording in the render fixture's case. It fails once, so the mount that replaces
it gets real modules and is a live document worth protecting; its own resize
listener is the witness that it started.

Two oracles were dropped. Vitest reports its own message when a mock factory
throws, not the one thrown, so which import failed is read from the factory's
counter instead. And a counter of successful factory calls read zero even though
the second mount got a working document, which measures vitest's caching rather
than this code; the live mount's listener replaced it.

* test(mobile): type the listener wrappers the mount pins install

The mobile tests-typecheck ratchet was red on 63eb8a40ae: six TS7006 implicit
`any` parameters in each of the two mount pins, from arrow functions assigned
over `window.addEventListener` and `window.removeEventListener`. An overloaded
method gives an assigned arrow no contextual parameter types, so each wrapper's
`type`, `listener` and `options` were implicitly `any` under
`tsconfig.test.json`, which the product typecheck does not read.

Both wrappers now take their parameters from the bound original as
`Parameters<typeof realAdd>` and spread them through, so the signature is the
real one rather than three widened parameters. No casts and no `any`.

Re-verified that the change did not quietly disarm either pin, because a recorder
that counted nothing would also go green: with `release` unguarded the rejection
case still fails on the live mount's markup, and with the adopt deferred by a
microtask the single-mount case still fails on the started document's resize
listener surviving its dispose.

The ratchet itself is the finding worth keeping. It is not part of the mobile
`tsc` the rest of my gate set runs, and it had dropped out of that set when these
folds began, so three reports listed the other ratchets and not this one. It is
back in, and stays in.

* fix(mobile): drop what a disposed page mount adopted, and close the fixture's three resources apart

Round 7's five items.

1. The queued-dispose case's precondition was vacuous. It read the host for a
missing container, which dispose empties on every path, so a build that returned
straight after its ownership check satisfied it. The wrapper now counts resize
adds and the case asserts exactly one, which is the document having started. Red
under that mutation, on the count.

2. The render fixture's rollback awaited its cleanup unguarded, so a cleanup that
also refused replaced the error the caller needs — the reason the setup failed.
The rollback is best-effort now and the original error is what comes back.

3. That cleanup stopped at the first throw, so a browser refusing to close took
the socket and the scratch tree with it, which is the leak the rollback exists to
prevent. Each of the three is asked independently and the first failure is
rethrown after all three have been tried.

4. The rejection case restores its `window` patch in a `finally`, as its sibling
does, so a failure part way through no longer leaves the patched functions behind
for everything that runs after it.

5. `dispose` left `started` set. `send` reads it, and what it holds names the
page's one set of document modules, so a stale handle could route a host command
into whichever document is live next. Nulled, and pinned: the stale handle pings,
and with the old code the *live* mount's `receive` answers `pong`, because the
scope's seam belongs to it by then. The precondition is the live handle's own ping
being answered, so the silence is the stale handle declining rather than the
command doing nothing.

Items 2 and 3 have no pin of their own. Both are failure paths of the cleanup
itself, reachable only by making a browser or a socket refuse to close, and
standing something in front of Playwright to do it is what the anti-slop gate
refuses in this file's suffix. The rollback's own pin still covers the path that
matters, and both changes are read by it.

* refactor(mobile): emit the terminal document as a factory

Ruling 22, commit 1 of C7.5b. The generator's concatenation already gave the 38
modules one function scope with one local `scope`; naming that scope a function is
what makes it the shape both hosts run, and what will let the page have its own
state per mount instead of a module singleton with a reset between them.

`createTerminalDocument(host)` is emitted around the same module bodies, in the
same order, followed by the same start sequence. It then declares `stop`, which
calls every module's stop in reverse order and takes back the frames the document
is still owed, and returns `{ send: handleMsg, stop }`. The native document is
that function plus one call with no argument, which is what the WebView has always
run: no argument means every seam is the window read it already did.

`createTerminalDocumentScope` takes the host and spreads the hooks it names over
the window defaults, filtering undefined so absent and present-but-undefined mean
the same thing. The emitted scope declaration is the one line the host reaches, so
the generator rewrites it and refuses if the line it expects is not there — a
rename would otherwise leave every call on the defaults with nothing to say so.

The golden moves by the wrapper and that one line, and by nothing else. 108,329 to
108,831 bytes, the whole diff:

  -(function() {
  +function createTerminalDocument(host) {

  -  function createTerminalDocumentScope() {
  -    return { ...createTerminalDocumentState(), ...createTerminalDocumentHostSeams() };
  +  function createTerminalDocumentScope(host = {}) {
  +    const named = Object.fromEntries(Object.entries(host).filter(([, hook]) => hook !== void 0));
  +    return { ...createTerminalDocumentState(), ...createTerminalDocumentHostSeams(), ...named };

  -  const scope = createTerminalDocumentScope();
  +  const scope = createTerminalDocumentScope(host);

  -})();
  +  function stop() {
  +    stopSurfaceTouchGestures();
  +    stopTapDispatch();
  +    stopSelectionOverlay();
  +    stopNormalBufferSmoothScroll();
  +    stopHostNotify();
  +    stopTerminalInit();
  +    stopWebglRecovery();
  +    stopFitScale();
  +    stopViewportTransform();
  +    cancelDocumentFrames();
  +  }
  +  return { send: handleMsg, stop: stop };
  +}
  +createTerminalDocument();

The byte golden and the payload hash are re-pinned once: 726,363 to 726,865 bytes,
sha256 9950f177 to c7bbcb0b.

Four test files sliced the document with their own copy of the IIFE bounds, which
ruling 17 allows moving. They now share one reader in the test-support module
beside the one that locates a single module, and that reader names the factory and
its call. Every assertion is unchanged. The module-order guard and the region
reader compare against the text the document carries rather than a raw emit, since
the scope module is the one the generator rewrites; both go through one exported
function so neither can describe the rewrite differently from the generator.

`TerminalDocumentHostSeams` and the new `TerminalDocumentHost` moved to
`document-host-seams.ts`, which owns the six functions they type. Types emit
nothing, so the golden is unchanged by the move; it keeps `document-scope.ts`
inside its 300-line cap with no disable and no bump.

* build(mobile): emit the page's terminal document factory beside the WebView's

Ruling 23, and the first half of C7.5b commit 2: the artifact the page will
import. The page cannot run the native script, because building a function from a
string needs `eval` and the page's policy refuses it, and it cannot run the
modules either, because they are one singleton while the whole point of the
factory is a scope per call. So one emitted body gets two wrappers.

`buildTerminalDocumentFactoryBody` is now the shared half: the modules in order,
the start sequence, the stop handle and the return. The native script wraps it in
the declaration and the trailing call, exactly as before. The new
`terminal-webview-document-factory.generated.ts` wraps the same lines in a
`@ts-nocheck` module whose only other content is the type import and the
annotated signature. One generator run writes both, so the page's factory cannot
be a build behind the WebView's.

`@ts-nocheck` covers this one generated file. Every line of its body is esbuild
output from a module that was type-checked at its source, with `declare global`
blocks and type re-exports already erased and constants already substituted; the
one line a caller reads is the signature, and the generator writes it with its
types. `TerminalDocument` joins `TerminalDocumentHost` in `document-host-seams.ts`
as the shape the factory returns.

The pin is byte equality. `document-factory-artifacts.test.ts` strips each
wrapper and holds the remaining text equal, so the byte golden pins the page's
artifact by construction rather than by a second golden; it also reads the file on
disk against what the generator would write now, since that file is gitignored and
built by postinstall, and it refuses a trailing call in the page's copy, which
would start a document as the module was imported.

The path joins `.gitignore` and the oxlint ignore list beside the engine artifact.
The consumer census gains the generated file by name: it is the document, and its
one import is the host contract its signature is written against.

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

* refactor(mobile): call the document instead of starting its modules

The page's half of ruling 23, and ruling 24. The mount plants the markup and calls
the factory; the handle is `send` and a `dispose` that stops it. The document is a
function, so the page holds an object per call and nothing else.

Deleted with the singleton it was written for: `page-document-modules.ts`, the
claim token and `liveDocument`, `release`, the owner-checked `dispose`, the
second-mount refusal, `resetTerminalDocumentScope`, the `adopt` callback, `ready`
and every pending-import path. All of it existed because two mounts shared one
module-level scope and because the handle had to come back before its import did.
A call is a document now, so a second mount cannot reach the first one's state and
a caller's cleanup cannot arrive before there is something to clean up. The
second-mount refusal is not replaced by a one-line guard: with a scope per call
there is no shared state left to refuse for, and a host element with two
documents planted in it is the caller's own doing, visible on the screen.

Ruling 24 splits `message-bridge` by what it is, which is what made the page able
to run this text at all. Two more seams, eight now: `installHostTransport`, whose
window default installs the `message` listeners on window and document and hands
back their removal, and `hasEngine`, whose default is the `window.Terminal` the
engine bundle installs. The page answers a transport that installs nothing,
because its transport is the handle, and an engine that is always there, because
the engine is the import above. So the page no longer takes the shell's frames or
reports a missing engine on every mount, and `stopMessageBridge` takes the
listeners off — the WebView never removed them, which ruling 21 asks for.

The refit the bridge happened to own moves to `fit-scale`, which is whose work it
is; both hosts start it, and the mount's hand-copied five calls are gone. The
engine's disposal moves into `stopTerminalInit` for the same reason: the mount
cannot reach the scope any more, and a stopped document's terminal is a WebGL
context nothing will read again.

The start sequence the generator emits is now inside the document's own undo: a
start that throws runs `stop` and rethrows, so neither host can be left holding a
listener from a build that failed. That replaces the deleted entry module's
unwind, and it covers every start rather than the four that had one.

Readiness arrives the same way on both hosts. The document posts `web-ready`
through `postToHost`, which the controller already handles, so the mount-side
`confirmWebReady` is gone. That flush is also the one caller that reaches `post`
before the effect has a handle, which is why the component's queue stays and now
says so.

The golden and the payload hash move, 102 diff lines: the two seam defaults and
their state fields, the reset gone, `startFitScale`, the disposal, the bridge over
its seams, and the start sequence inside its try.

Tests: the seam tests and the unwind test move to the factory and the derived
start sequence; the frame registry builds a fresh scope instead of resetting one;
the two mount test files and the page entry's order test go with their subjects.
The render check keeps every behavioural case and loses two whose subject the
static import removed — a Reload while the chunk is in flight, and a chunk that
will not load, which is now the route's chunk rather than the document's.

* test(mobile): stop censusing state a call of the document already isolates

Ruling 22 answers what ruling 21's state half was for. A module's top level is
emitted inside the factory, so a `let` there is one binding per call — which is
exactly what moving it onto the scope was achieving. The census that refused it,
and the planted-module precondition beside it, go.

The effect half stays, and the distinction is what a stop can reach. An effect in a
module body runs at the position its module is emitted rather than in the start
sequence, so no stop function undoes it and each call leaks another one. A binding
leaks nothing.

* test(mobile): stop the derived start sequence warning on every suite run

The helper reaches its neighbours through a variable specifier, which the bundler
answers by rewriting as a glob — and it refuses to glob the directory the import is
written in, so every suite that loads this file printed the refusal twice.

`@vite-ignore` leaves the specifier alone and the module runner resolves it, which
is what was already happening. An extension does not help: with one the refusal
becomes the own-directory rule, and the path alias is not resolved for a runtime
specifier at all.

* test(config): separate the two commits inside the closure reading

The factory arriving is not the whole -1,890. Making the document a factory put the
`host` argument on `createTerminalDocumentScope`, which is this lane's only edit to
a module the closure already carried, and that alone is +80. Both numbers are in
the note now, so neither commit's cost is read as the other's.

* fix(mobile): read a document's elements from the host it was planted in

The last thing two documents on one page shared. Ruling 22 gave each call its own
scope, but the element reads were `document.getElementById` and the ids are in the
markup every host plants, so the second document's start sequence took the first
host's surface, overlay, handles and menu — two documents driving one terminal,
with the second host left empty.

Reachable, not theoretical: expo-router keeps the outgoing screen mounted for the
length of a stack transition, so two routes that both hold a terminal have two live
documents on the page while the animation runs.

`root` joins the host argument and `elementInRoot` is the one reader; the ten reads
in runtime-constants, surface-swap, selection-state-and-eviction and text-scaling go
through it. No id is renamed and nothing is refused: two documents on one page are
two terminals.

Two deviations from the ruling, both about *when* the default is read. `root` is
`ParentNode | null` with null meaning "the page I am in", rather than defaulting to
`document`: a data default is evaluated whenever a scope is built, which put a DOM
read into every slice evaluation and took eight keyboard-avoidance cases down with a
`ReferenceError` in their `vm` context. Null defers it to the read, which is the rule
the eight seams above it already follow. And the reader lives in
`document-host-seams.ts`, which declares the type, taking the root as an argument:
in `document-scope.ts` it was four lines over the file's 300 (no bump, no disable).

Red first, and the red was the second document: with a page-wide read the second
engine opens on an element outside its own host. `document-host-root.test.ts` plants
two hosts, starts a document in each, and reads which surface each engine was opened
on through the `createTerminal` seam, because the scope is not reachable from
outside. Falsified again after the fix by pointing the emitted reader back at
`document`: red, one case.

Two neighbours checked while here. The document-level touch listeners are already
host-scoped, because every handler tests its target against the scope's own surface,
overlay and handles, which are now this document's. `window.__engineErrors` is the
one page global left, and it is now kept rather than replaced per mount: a capped
diagnostic buffer, where a second mount was costing the first its captured lines.

Golden 27 diff lines, hash and length repinned: the reader, the `root: null`
default, and the ten reads.

* test(mobile): type the two-host engine double as the shape the seam returns

The double was reaching `createTerminal`'s return type through
`as unknown as Parameters<typeof queueMicrotask>[0] & never`, which the type-aware
gate reads correctly as an intersection with `never` and which was a cast standing in
for naming the type.

`TerminalDocumentTerminal` names it. Every member the type declares is present — the
ones `init` and the start sequence reach do something, the rest answer in the shape
their caller reads — and the shape needed no narrowing to accept a double. Two things
the type does not declare moved off it: where `open` was called is handed back beside
the terminal rather than exposed as a second getter, so the literal carries nothing
excess, and the buffer gained the `getLine` the type requires.

No cast, so nothing to write a SAFETY line about. Still red without the fix, checked
again after the retype by pointing the emitted reader back at `document`: one case.

* fix(mobile): filter a document's page-wide touch listeners to its own host (OTA phase C, C7.5b round 1)

Round 1 H1. The dispatcher's four listeners are on `document`, so with two
documents on one page (legitimate since `712daa80e6`) each is handed the other's
touches, and the two-finger branch acts before any target filtering: a pinch in
host B posted `mobile-clip-cancel-by-pinch` from document A and dropped A's
selection. Fixed at the source, one predicate beside `elementInRoot`, asked once
at the top of each handler rather than inside a branch. `root === null` is the
WebView, where the document is the page, so it answers yes to everything and the
native document is unchanged.

`e.target` is the element the finger went down on for the life of the touch, so a
select-drag travelling outside the host still answers yes on move, end and cancel.

Census of every global listener install under `src/terminal/document/` (non-test):

- `tap-dispatch.ts:241-244`, four capture-phase `document` touch listeners
  (touchstart, touchmove, touchend, touchcancel): MUST be root-filtered; this fix.
- `document-host-seams.ts:165-166`, `window`+`document` `message` in
  `installWindowHostTransport`: WebView-only. It is that host's transport seam
  default and the page installs nothing (ruling 24), so no page carries two.
- `fit-scale.ts:163`, `window` `resize`: page-wide by nature. A viewport change
  concerns every document on the page and the event has no target in either host;
  both must refit.
- `webgl-recovery.ts:104`, `document` `visibilitychange`: page-wide by nature.
  Backgrounding concerns every document on the page; its target is the document.
- No document-level mouse, wheel, keyboard or selection listener exists: those
  are all on `targetSurface` or the menu buttons, read through `elementInRoot`,
  so they are already inside their own host.

Red-first, the reviewer's own repro in `document-host-root.test.ts`: A and B both
in select mode, a two-finger touchstart in B's surface. Before: 2 failed
(A posted the pinch cancel too, and the control in A's own host cancelled B).

* test(mobile): unit-test the page mount's three paths no happy path reaches (OTA phase C, C7.5b round 1)

Round 1 M2. `terminal-web-document-mount.ts` had no unit test: the only reading
of it was the render check, which drives the whole page bundle in a browser —
right for behaviour, too coarse for three lines that only a failure reaches.

The body's "five test files whose subjects no longer exist" is wrong for three of
them. What ruling 22 deleted was the machinery (the claim token, `liveDocument`,
the owner-checked dispose, the second-mount refusal); these three subjects
survived it and lost their only cover:

- both engines disposed when a swap never committed (`terminal-init.ts:203-213`);
- the host given back when a start throws (`startDocumentOrGiveTheHostBack`);
- the component naming that throw's cause (`TerminalWebView.web.tsx:83`).

`terminal-web-document-mount.test.ts` (happy-dom) covers all three against the
real generated factory. Only the factory's *arrival* is mocked, delegating to the
real `createTerminalDocument` except for the one case that makes a start throw, so
no stub stands in for the program under test.

Six cases, each red against a deliberately broken line:

- two distinct terminals both disposed. Broken `new Set([scope.term,
  scope.committedTerm])` -> `new Set([scope.term])`: expected [1,1], got [0,1].
- the same terminal disposed once. Broken the set -> a plain array: expected 1,
  got 2. The pair is the dedup's own oracle; either half alone passes for the
  wrong reason.
- the host emptied and the class dropped on a throw. Broken by deleting the two
  lines in the mount's catch: host still carried `#terminal-container`.
- control: a live document keeps the markup and the class, so the two assertions
  above cannot pass for a mount that planted nothing.
- `onEngineError` gets `terminal document failed to start - engine missing`.
  Broken by deleting the component's `receive` in its catch: expected one
  message, got none.
- control: nothing reported when the document starts.

The engine double moves to `document-terminal-double.test-support.ts` and both
readers of the seam share it; a second hand-written copy of thirty members would
drift as the shape grows. It now counts disposals beside reporting `open`.

Terminal suite 67 files / 625 tests -> 68 / 631. No product line changed, so the
golden and the payload hash do not move.

* test(mobile): pin both generated wrappers, and say what a shadow root would break now (OTA phase C, C7.5b round 1)

Round 1 M1 and L2.

M1, the mount's stylesheet comment was one version behind: it said the document
reads its elements with `document.getElementById`, which `712daa80e6` replaced
with `elementInRoot`, and drew its shadow-root conclusion from that read. Both
halves re-derived rather than reworded. A shadow root no longer breaks the reads
(`elementInRoot` is a `querySelector` under the host, which a shadow root
answers); it breaks this sheet, because a rule in the document's head does not
cross a shadow boundary, so it would have to move inside each root and be parsed
once per host instead of once per page.

L2, `document-factory-artifacts.test.ts` anchored the page body at `):
TerminalDocument {` and nothing else, so the header, the `@ts-nocheck` line, the
`import type` and the parameter's own line could all drift with the test green —
and that signature is the one line a caller of the page's artifact reads. Both
wrappers are now literal lines: nine for the page (header, directive, import,
blank, the three-line signature) and one plus two for the native script
(declaration, closing brace, trailing call). Literal rather than the generator's
own constants, which would only agree with whatever it emits.

Red controls, each with the generator changed and then restored:

- the page's `import type` reordered to `{ TerminalDocumentHost, TerminalDocument }`:
  2 failed ("the page module opens with its wrapper", and the on-disk reading).
- the native trailing call changed to `createTerminalDocument({});`: 1 failed
  ("the native script closes with its wrapper"). The old anchor caught neither.

No emitted line moved: golden and payload hash unchanged, terminal suite 68 files
/ 631 tests.

* refactor(mobile): thread the document scope and bundle the page's script

Ruling 25. The terminal document stops being a string the build machinery assembles
and becomes ordinary TypeScript: every module function that reads document state takes
`scope: TerminalDocumentScope` as its first parameter, `document-scope.ts` exports the
types and `createTerminalDocumentScope(host)` and nothing else, and `tsc` is the oracle
that the threading is whole (a missed parameter is a type error).

`create-terminal-document.ts` is hand-written, not emitted: it builds the scope, runs the
eleven starts inside a try that unwinds on a throw, stops the ten in reverse with
`cancelDocumentFrames` last, and returns `{ send, stop }`. `native-document-entry.ts` is
one statement. The concatenator becomes an esbuild IIFE bundle of that entry at the
Chrome 74 floor, written as a string the same way the engine artifact is.

The byte pin cannot survive that and does not try to: esbuild merges module scopes and
renames the threaded parameter (`scope` -> `scope2` where two modules collide), so the
document's text is no longer a stable artifact and the behavioural suites are the proof.
`native-document-bundle.test.ts` evaluates the real bundle and reads three behaviours the
phone depends on: it announces `web-ready`, an init message opens the engine inside
`#terminal-surface`, a ping is answered, and a missing engine global reports fatally
instead of starting.

Rewritten tests, old oracle -> new oracle:

- host-seams, write-queue, document-frame-registry, document-parse-time-effects:
  evaluated a region of the generated text -> import the module and pass a scope the case
  builds.
- terminal-webview-engine (WebGL recovery), terminal-webview-theme,
  terminal-webview-text-zoom, terminal-webview-query-reply,
  terminal-keyboard-avoidance-webview: a `vm` evaluation with injected globals -> the
  imported functions over a scope whose seams are the case's own doubles.
- terminal-webview-url-tap: a function extracted out of the document's text and evaluated
  -> the document's `osc-link-tap` exports imported directly.
- terminal-webview-reflow, terminal-webview-scroll-routing, terminal-path-tap,
  terminal-webview-tap-routing, terminal-webview-wheel-scroll: assertions over the
  assembled document text -> the same assertions over the module's own source, read
  through `document-module-source.test-support.ts` (TypeScript, so no semicolons).
- document-host-root, document-start-unwind: imported the generated factory -> import
  `create-terminal-document`.
- terminal-webview-consumer-census: the generated factory was a census exception -> it no
  longer exists.
- config/scripts closure tests: re-measured for the bundled document.

Deleted with the machinery they served: the concatenator's emit/substitute/order code,
`terminal-document-module-order.mjs`, the document fixture builder,
`generated-document-region.test-support.ts`, the byte golden and its identity test, the
payload-hash pin, `document-factory-emit`, `document-factory-artifacts`,
`document-module-order`, and the generated factory artifact with its gitignore and
lint-ignore lines.

Two assertions the tests no longer need: the published contrast floor arrives unvalidated
from a host of unknown version, so `TerminalDocumentThemeMessage` types it the way the
router types its other wire fields and `normalizeTerminalContrastOverride` remains what
decides it is a number; the recovery harness holds its timer callback in a wrapper rather
than asserting a narrowing.

* refactor(mobile): dissolve the document's constants module into its owners

`document-constants.ts` existed because the document was a string: a string cannot
import, so the generator substituted JSON literals into the text and the web page imported
the same bindings to keep one source. The document imports now, so the indirection is a
re-export shim over four real owners and each site reaches the owner instead.

- `terminal-theme.ts` takes the background fallback from the theme's own `colors`.
- `url-tap.ts` imports the two patterns and the length cap from
  `terminal-webview-url-tap.ts`, which is where the page's copy reads them, and the three
  local aliases go with the substitution they were shaped for.
- `text-scaling.ts` and `document-scope.ts` take the presets from `storage/preferences`.
- `terminal-init.ts` and `document-scope.ts` take the caret options and the built-in theme
  from `terminal-webview-html/theme.ts`.

One test oracle moves with it: the URL tap's "both copies spell the pattern identically"
case pinned the substituted assignment line, and now reads the document module's import of
the page's own constant. The resolver cases that compare the two behaviours are unchanged.

* fix(mobile): count only the fingers inside this document's own host (OTA phase C, C7.5b round 2)

Round 2's residual of `9824145e1f`'s class, one level in. `eventTargetInRoot`
settles whose event it is; every branch then counts `e.touches`, which is every
finger on the screen. A finger resting in host A is therefore B's second finger:
a one-finger touch in B's own surface reads `length === 2`, latches a pinch and
drops B's selection, and on touchend `length === 0` is never true so B's surface
tap never fires.

`touchesInRoot(root, touches)` beside `eventTargetInRoot` returns this document's
own fingers, and every count and index reads through it. A list rather than a
count, because `touches[0]` and `touches[1]` are page-wide in exactly the same
way as `touches.length` — the first finger on the screen may be the other
terminal's. `root === null` is the WebView, whose fingers are all its own: the
list is returned untouched, so nothing is allocated on a path that runs at frame
rate.

Census of every `touches` / `changedTouches` / `targetTouches` read under
`src/terminal/document/` (non-test). There are no `changedTouches` or
`targetTouches` reads at all; every read is `e.touches`:

- `tap-dispatch.ts`, 15 reads across the three handlers that take an event
  (`[0]`, `[1]`, `.length`, and the list handed to `touchById`): MUST be filtered.
  The document listens on `document`, so the event and its list are both page-wide.
- `surface-touch-gestures.ts`, 18 reads across its touchstart, touchmove and
  touchend handlers: MUST be filtered. These listeners are on the document's own
  surface, so the event is always this document's — but the list inside it is
  still every finger on the screen, which is the whole defect.
- `tap-dispatch.ts:21-24`, `touchById(touches, id)`: no filtering of its own. It
  reads whatever list it is given, and all three callers now hand it a filtered
  one; its parameter widens from `TouchList` to `ArrayLike<Touch>`.

Red-first in `document-host-root.test.ts`, the reviewer's two repros, with the
three product files at `aba99c3e4f` and the artifacts rebuilt: 2 failed / 3
passed (pinch cancel posted with one finger on B's overlay; `terminal-tap` never
posted). With the fix: 5 passed. The pinch-inside-own-host control stays, and the
first repro lands on B's menu pill rather than its surface, because a single
finger on the surface dismisses a selection by design — on the pill, keeping the
selection is the whole assertion.

`document-host-seams.ts` also rewritten in the present tense where it read as
history.

Golden re-pinned: 19 hunks, +51/-33. `touchesInRoot` emitted after
`eventTargetInRoot`; one `const touches = touchesInRoot(scope.root, e.touches)`
at the top of each of the six touch handlers, and every `e.touches` read inside
them now reads `touches`. Document 728,589 -> 729,152 bytes, sha256 1556f532...
-> 02633389...

Correction to `9824145e1f`'s message: it cites `tap-dispatch.ts:241-244` for the
four installs, which at that commit are `261-264` (the line numbers are the
pre-fold ones from the review).

* refactor(mobile): fold the document's never-written constants out of the scope

Seventeen scope fields were never assigned after the factory built them. They were fields
because the generator substituted them into one function scope and a module cannot import
into a string; each is now a `const` in the module that owns it.

- `escape-introducers.ts` holds `ESC` and `C1_CSI`, as the bytes rather than as
  `String.fromCharCode` calls a JSON substitution needed.
- `write-queue.ts` owns the status dot, its two presentation selectors, the pattern and the
  DECSET tail limit. The pattern is a regex literal: a `new RegExp` at a module's top level
  is parse-time work, which ruling 20 refuses and the census measures.
- `fit-scale.ts` owns `MIN_FIT_COLS`, `text-scaling.ts` the ends of the preset range,
  `tap-dispatch.ts` the press and tap thresholds, `selection-range.ts` the word pattern and
  `selection-overlay.ts` the edge-scroll distance and tick.

Four functions stop taking a scope they no longer read: `isStatusDotPresentationSelector`,
`endsWithStatusDotPresentationSequence`, `extractMouseModeScanTail` and, with
`normalizeInitialData`, `isAltScreenActive`.

`runtime-constants.ts` held no constants once they moved out, only the surface element read.
That read is the first line of `startSurfaceSwap` now, which is the module the field is
documented as belonging to, and the start sequence is ten calls rather than eleven.

The engine error buffer becomes a seam, `capturedEngineErrors`. The WebView's `<head>` keeps
its own: it opens before the engine script tag, so an engine that throws while loading is
captured by something no document has started yet, and the first report quotes it. That is
why the head declaration stays where the design said it would go — the page's mount answers
the seam with a buffer per mount instead of assigning a window global, which is what the
document no longer touches.

Two of the page's three casts are gone, and tsc is what says so: xterm's cell attribute
getters answer numbers, and `getLine(...).getCell` answers `undefined` rather than null, so
the shape now describes the engine it was written against. The third stays with a narrower
reason: `getCell` takes back the cell xterm allocated, and describing that parameter means
naming xterm's whole cell type where the document declares the six members it reads.

Comments that narrated the extraction — the scope table's `var` census, "the flip", "the
main slice", "C7.1 extracts" — say what the code does instead.

Oracles that moved with the constants: the reflow floor and the status dot now read the
owning module's `const` rather than a scope-factory line; the write-queue harness resolves
the module's one value import; the parse-time census asserts the stronger fact that no
module does parse-time work, with the element reader aimed at every module and its presence
proved by the planted case.

* docs(mobile): re-measure the session route's closure for the threaded document

The reading in the closure test's note is against `origin/main` at ec82173130, measured the
same way on both sides: the route and its layout built as their own entries, the route's
output taken minified.

  modules        4320 -> 4321   (+1)
  local modules   970 ->  971   (+1)
  minified bytes  3,768,122 -> 3,764,932   (-3,190)

The +1 is three modules in and two out, which the note names. The bytes fall for two
reasons the lane can point at: a threaded parameter minifies to one character where a
shared object could not, and a constant folded into the module that owns it is inlined
where `scope.X` was a property access the minifier had to keep.

* fix(mobile): keep AsyncStorage out of the WebView document, and prove it

The 13 KB the bundle grew is not esbuild's lazy `__esm` wrappers and not a cycle: there
are none of either. It is a dependency that rode in. `text-scaling` reached
`storage/preferences` for the text-scale presets, and that module imports AsyncStorage, so
the phone's document carried AsyncStorage, `merge-options` and `is-plain-obj` — 11.6 KB of
storage library inside a string with nothing to store, wrapped in esbuild's CommonJS
interop. The old generator hid this: it substituted the presets as a JSON literal, so the
import never reached the emitted text.

The presets move to `terminal/terminal-text-scales.ts`, a leaf with no imports of its own,
which `storage/preferences` imports and re-exports for the settings screen. The bundle:

  113,442 characters, 3,465 lines, 47 inputs, none from node_modules
  was 120,217 characters with 6 node_modules inputs and three `__commonJS` wrappers
  the golden it replaces was 110,085 bytes

`minify: false` stays, for the reason given: the overlay reports the line and column
`window.onerror` hands it.

Three cases join the bundle evaluation, and each was made to fail before it was kept:

- A `set-theme` and a `write` before `init`, which is what a byte golden covered by
  accident. Read from the router rather than assumed: the theme applies to the scope and
  paints through the seam, the chunk normalises and queues, the pump returns because there
  is no terminal, and `init` then resets the queue and the mode scan so the early chunk is
  dropped and the init frame's own theme wins. Deleting `resetWriteQueue` from `init` makes
  the terminal write `early chunk\x1b[0mreplayed` — the early bytes ahead of the snapshot,
  which is the corruption the reset prevents.
- The transport, both ways: the native document installs `message` on `window` and on
  `document` and keeps them, because the WebView never stops its document; the page's
  factory with a no-op transport installs none, so none of the shell's own frames are taken.
  Installing on one target fails the first half, installing a real listener the second.
- What the bundle carries: no input from node_modules, no `__commonJS`, no `__esm(`.
  Pointing the presets back at `storage/preferences` fails it with the six inputs named.

The build options become one object the census and the build share, so what is measured is
what ships.

* docs(mobile): correct the closure reading for the text-scale leaf

The presets moving to their own module adds one more to the page's closure than the reading
recorded, and five bytes with it. Measured the same way on both sides.

  modules        4320 -> 4322   (+2)
  local modules   970 ->  972   (+2)
  minified bytes  3,768,122 -> 3,764,937   (-3,185)

* docs(mobile): separate the lane's closure reading from main's

The byte figure in the note was measured before `origin/ota-c7-5b-document-factory` and the
main it carries were merged in. This head reads 3,765,180; the 243 between the two are the
touch-root predicates and main's #21687 momentum change, which are not this lane's to claim
in either direction. Both numbers are named rather than one of them silently replaced.

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

* test(mobile): compare the start sequence with what the modules export, by name

Round 1's finding on the census: completeness was a count, so a module exporting a start
nobody calls red only as `expected 11 to be 10` and greened again the moment the literal
moved with it. The two sets are compared by name now, with the order asserted as well: the
starts the factory calls are every exported `start*(scope)` there is, the stops are every
exported `stop*(scope)`, and the stops of modules that have both run in the reverse of the
order their starts did.

`cancelDocumentFrames` is held out of the set comparison and asserted by position instead —
last, after every stop that might still hold a frame. `stopEdgeScroll` is the one exported
stop the sequence does not call, and it is not a lifecycle undo but the overlay's own for a
drag that is over; the test asserts `stopSelectionOverlay` reaches it rather than waving it
through.

The names come from the tree rather than the text, because a regex over the file would also
match the sequence's own name in the unwind inside `startTerminalDocument`'s catch.

Red-first control, `export function startReflow(scope)` added to `reflow.ts` and not called:
the set comparison fails naming `startReflow`, where the count failed with a number. A
second case plants the same shape against the reader itself, so the comparison is a
measurement rather than an agreement between two empty lists.

* test(mobile): read the bundle census and the artifact off one build

Round 1's finding: the input assertion built the bundle while the wrapper assertions read
the committed string, so under the presets-to-preferences control the rebuild red and
`__commonJS` passed against a stale artifact. And `inputs.length > 40` was a bound, not a
census.

`terminalDocumentBundle()` returns the text and the module list from one build, and
`buildTerminalDocumentScript` is that function's text — so the thing measured is the thing
written. The case asserts the exact input count, no node_modules input, neither wrapper, and
that the committed artifact equals what the sources build. A stale artifact now reds.

Controls: the presets pointed back at `storage/preferences` fails on the inputs and on
`__commonJS` in the same run; `MIN_FIT_COLS` changed to 21 without rebuilding fails the
equality. Worth knowing for the next reader: an unused export or a dropped comment does not
fail it, because esbuild does not emit either — the assertion is about what ships.

* test(mobile): show that the page's capture buffer is written, and say what writes it

Round 1 read the page's `capturedEngineErrors` array as never written and asked for an empty
readonly list instead. It is written, and the empty list would drop a line from every report
the page makes: `startHostNotify` installs the reporter through `installErrorReporter`,
which on the page is a `window` error listener, and the reporter appends each error it
forwards before `reportEngineError` quotes the buffer back. `host-notify.ts` is the file that
proves it; the comment on the mount said none of this and now says it.

The pre-start window round 1 asked about is the half the page genuinely cannot have. The
WebView's `<head>` opens its buffer before the engine script tag, so an engine that throws
while loading is captured by something no document has started; on the page the engine is a
static import of this module, so there is nothing to capture before the document exists.

Red-first: two errors dispatched at a real mount, and the reports quote `captured: first
failure` then `captured: first failure | second failure`; a second mount quotes its own line
and not the first document's. Answering the seam with `() => []`, which is what round 1 asked
for, fails the first assertion.

* docs(mobile): put the engine doc block back on the engine seam, in the present tense

Round 1's last two. The block describing how the WebView knows the engine is there had ended
up above `windowCapturedEngineErrors`, one function too high; it is on `windowHasEngine`
again, with that function's own note about the optional global folded in.

Two references that had outlived what they named: the host-seams case cited
`runtime-constants`, which this branch deleted when its one element read moved into
`startSurfaceSwap`, and now cites modules the sequence still has; the query-reply harness
narrated what its oracle used to be instead of what it is.

* style(mobile): reverse the stop order without mutating the list

`Array#reverse` mutates, which the lint rule refuses and which would have left the census
comparing a list it had just reordered. `toReversed` on the filtered copy says the same thing
and cannot.

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

* style(mobile): put every document import back in its import block

pullfrog caught `fit-scale`, where `scheduleDocumentFrame` sat below `MIN_FIT_COLS`. A
statement walk over all 41 non-test modules under `document/` — the tree, not a grep, so a
multi-line import or one inside a comment cannot hide — found one more: `host-notify` split
its two `document-host-seams` lines around the re-export between them. Both imports moved up;
the re-export stays where it was, below the block, with its comment in the present tense.

The sweep reports no misplaced import across the 41 modules now.

* test(config): name the haptics module inside the merged session-closure reading (OTA phase C, C7.5b)

The merge's re-measured 4284 sat one above this branch's -40 added to PR B's +3,
and the comment could only say main had drifted "a module of its own". It is
`src/mobile-web-shell/bridge/bridge-haptics-notify.ts`, which C7.10 item E put on
the session route after PR B recorded 4323 — so pristine main reads 4324 against
the 4323 it holds, which is what #21908 re-pins.

Named here as #21908 names it on main. Nothing measured changes: 4284 is the same
number, and the module is in it by main's route rather than by anything this branch
did. `haptics.web.ts` was already in the closure; the bridge module joins it.
Verified by reading the closure's own module list rather than inferred from the
count: both haptics modules are in `local`, with the artifact-level totals
unchanged at 4284 / 934.

Which is why the reading is re-measured and not summed. A merged number arrived at
as -40 plus +3 would have read 4283 and been wrong about a module neither side of
the merge touched.

After #21908 lands, a further merge of main reconciles the two comments.

* test(mobile): stop every document a host-seams case started

CodeRabbit's finding, and it measures: `startedScope` runs the whole start sequence and no
case stopped it, so the `afterEach` restored the globals and left the listeners. A start
installs six on `document` and `window` — the dispatcher's four capture-phase touch handlers,
the fit's resize and the recovery's visibilitychange — and those are page-wide by nature, so
a document nobody stopped keeps answering events in the next case, with a scope that case has
never seen and host hooks that belong to the case before it.

Every started scope is tracked and stopped in the existing `afterEach`, before the globals go
back, because a stop reads the scope's own seams and one of them is a window read a case may
have stubbed.

Measured by counting `addEventListener` and `removeEventListener` on both targets across the
file's run: 18 added and 0 removed before this, 18 added and 18 removed after. For a single
case it is 6 and 0 against 6 and 6.

* docs(mobile): pair each doc block with the declaration under it

Two comment placements, both mine and both from the merges.

The closure test's `SESSION_ROUTE_MODULES` block opened twice: my conflict resolution kept
the opener that was above the marker and supplied another with the replacement text, so the
file carried a literal `/**` inside the block it opens. Nothing flags that, because it parses
as one comment. Swept the rest of the files the merge touched for stacked openers and for
stray markers; there are none.

In the host-seams case, `startedScopes` and its block landed between `startedScope`'s doc
comment and the function, which left the function undocumented and stacked two blocks on the

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`.

* 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(mobile): name the confirm setter this callback already calls in its deps

A `useState` setter is stable, so the identity of the callback is unchanged; the list now

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* 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.

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

* 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.

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

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

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

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.

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

* test(mobile): pin the ready deadline to the page's own retry ceiling

The margin was stated in a comment and asserted against itself, so changing
either number left the suite green.

* 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
host. It names the shell's own bug now, and carries the issue.

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

* 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.

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

* test(mobile): name routes in the manifest field list the builder emits

C1.3 added `routes` to every manifest this builder writes, and the Phase A
contract test still listed eight keys, which is what went red in CI.

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

* test(mobile): hold a navigate target to the same segment rule as the shell's

The href pattern is built from the segment source C1.2 tightened, and nothing
said so: a spelling one pattern refused while the other took it would be a hole
with a `notify` already pointed at it.

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

* fix(mobile): name the key a refused page write reached for

The last diagnostic still falling through to the line about a view outliving its
host, on the branch that added it. The key is the evidence: it says which host's
pinned list the page was reaching into.

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

* test(mobile): give the ref-refresh probe the navigations this branch added

C1.1's new case builds its own probe, and on this branch a probe also collects

the tests ratchet caught.

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

* 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.

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

* 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.

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

* test(mobile): split the bridge frame suite along the modules the merge created

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

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

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

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

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

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

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

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

Jinwoo Hong 47d107cf2e feat(mobile): hybrid shell route, dark behind a dev-only flag (OTA phase B, 4/4) (#21435)
* refactor(mobile): say whether a host status was readable, and carry its protocol window

`useHostStatusGates` settled the same closed gates for a host that answered
`status.get` with no capabilities and for one whose status nobody could read:
both paths produced an empty capability list and an `ok` verdict. A caller that
walls on a missing capability cannot tell those apart, and the mobile web
bundle's wall is terminal, so it must never fire for the second.

`statusReadable` distinguishes them. `hostProtocolWindow` exposes the two
protocol numbers the hook already read for `evaluateCompat`, as the reply's own
fields, so the bundle wall can evaluate its own window without a second
`status.get`. Both are additive; no existing consumer changes.

* feat(mobile): add the hybrid shell flag and the generation path both loaders demand

`orca:mobileWebShellEnabled`, default off and unreadable-is-off, in the same
shape as the terminal autocomplete flag.

`generationDirectoryPath` converts the store's `file://` uri to the absolute
path the native shell view requires: both `MobileWebShellGeneration.load`
implementations refuse anything without a leading slash, and `expo-file-system`
only ever hands out uris.

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

* feat(mobile): the hybrid shell session as a pure reducer

Every decision the route makes, as `(session, event) -> (state, effects)`: the
capability wall, the lazy sweep and cache read, the manifest check, the cached
build-id hit that skips paging, the offline open with no compat check, and the
three recovery rules the native shell view's contract states.

Pure, so the rules are table tests rather than a simulator run. Two latches sit
beside the state because both outlive it: `retriedOnce` spans the delete and
refetch that returns to `checking`, and `remountedOnce` spans a `ready` replaced
by a `ready` under a new session id.

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

* feat(mobile): the hybrid shell route, dark behind a dev-only flag (OTA phase B, 4/4)

Wires the four Phase B and A pieces together and adds no decision of its own.
`h/[hostId]/web` sits inside the existing `HostProtocolGate` tree, so the native
`desktop-too-old` wall still applies above it. With the flag off — every store
build, since the only writer is a `__DEV__` Troubleshoot toggle — the route
redirects to `h/[hostId]` and the screen is never constructed, so nothing is
fetched, written or swept.

The runner owns only the impure edges and checks an epoch before every dispatch,
so an unmount, a host change or a retry abandons work in flight and aborts a
download that would otherwise hold four of the host's read slots. The native view
is keyed on the session id, which is what makes the reducer's remount a rebuilt
WebView with every fence reinstalled.

A census test pins who touches the flag: the route reads it, the developer row
reads and writes it, and the key itself lives in one module.

on `disconnected`. It dials, fails, schedules a retry, and cycles `connecting`
-> `reconnecting` -> `connecting` with the delay growing to a minute. Mapping
`reconnecting` to "still connecting" left a phone holding a verified cached
generation on `checking` forever instead of opening it, which is the one case
the offline rule exists for.

`connecting` and `handshaking` are the first dial and still wait; everything
else is unreachable. The mapping moves next to the reducer it feeds, because it
is a decision and the runner is supposed to hold none.

* test(mobile): build the reachability stub instead of asserting it

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

* refactor(mobile): move the shell session vocabulary into its own module

Pure move, no behaviour: the states, events, effects and gates the reducer
and its runner share now sit beside the reducer rather than inside it, so
the transition rules have room to grow under the file's line budget.

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

* fix(mobile): drop a shell effect result whose flow has been superseded

Every restart of the flow bumps a number the effects of that run are stamped
with, and a result echoes it back: a manifest read still in flight when the
socket drops used to reject after the offline path had already opened the
cached generation, replacing a displayed workspace with a download failure,
and a status refetch arriving mid-check used to run the cache read and the
download twice. The gates restart no longer clears the remount latch either;
only the retry button does, so a reconnect cannot grant a second remount.

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

* test(mobile): census the flag across modules, not just src and app

The native view tree was outside the scan, so a reader added there would
have passed an assertion that reads as exhaustive. Proven by adding one to
the shell view module: the census fails.

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

* fix(mobile): let only the state that mounted the view hear the view

A native batch reports two failures in a row, and the reducer applied both:
document-load-failed started the delete-and-refetch, render-process-gone
then made it terminal without a new flow, and the cache read the recovery
had already asked for dragged the session back to checking behind a failure
screen. A report arriving outside `ready` is from a view that is no longer
on screen, so it changes nothing.

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

* fix(mobile): say a host status could not be read instead of spinning on it

A transient status.get failure settles the gate unreadable and nothing probes
it again, so the route sat on "Checking host" for as long as anyone left it
there and Try again re-read the same settled answer. It now says what
happened and offers no retry, and a status that does become readable picks
the flow back up on its own.

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

* fix(mobile): restart the flow on the verdict that changed, not on every gates object

A reconnect cycle rebuilds the gates several times a second with the same
answer in them, and each one re-swept the staging tree and flipped an offline
screen to a spinner and back. Only a changed verdict restarts now, which is
also why the gates effect has to depend on the host id: two hosts whose gates
read identically would otherwise leave the second session in `checking`.

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

* test(mobile): cover what only the shell runner can get wrong

Three cancellations had no test: the epoch that stops a result reaching a
session that is gone, the unmount cleanup that aborts the download, and the
retry that does both before starting over. Each is now red under its own
mutant. The download also re-checks the abort before it writes, since an
abort landing between the fetch's last read and the commit would otherwise
still put a generation on disk for a screen nobody is on.

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

* fix(mobile): write the shell runner's refs after the commit, not during render

React can replay or discard a render, so a handle written during one can run
effects for a session that never existed. The client and the host cache key stop
being refs at all; the effect handle is committed in an effect above every
effect that dispatches.

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

* fix(mobile): keep the hybrid shell flag unreadable outside a development build

Development and release share a bundle id, and the iOS data container survives
an install-over, so a flag a developer toggled on would follow the store build
in and mount the shell on a deep link. The release read never reaches storage.

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

* test(mobile): drive the route's flag read as each build kind reads it

The route test exercises the real preference read, so it has to say which build
it is. A store build whose container kept a development toggle redirects.

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

* fix(mobile): let a cache read that lands mid-dial wait for the compat check

A connection still being made is not a host that cannot be reached. Opening the
cached generation there skips the compat check the landing connection is what
makes answerable, so only `unreachable` takes the offline path now.

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

* fix(mobile): move the developer toggle only after its write lands

The route reads the flag back from storage, so a switch that moved on the tap
let the open button race the value that was being persisted. The switch and the
button both stay put until the write settles, and a failed write keeps the
previous position.

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

* test(mobile): say which build kind a test runs as without asserting on globalThis

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

* fix(mobile): undo a staged generation the abort reached before the commit

The commit is the write staging cannot take back: it renames into the active
slot and moves the host index. An abort landing while the bytes were being
staged now removes the staged tree instead of activating it.

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

* fix(mobile): open the cached workspace when the link, not the bundle, cut a read short

An RPC rejection can reach the reducer before the reachability change does, so
the offline gate never fires and a phone holding a valid generation reads that
the workspace could not be downloaded. A read that failed on the link now opens
what is on disk, the same path offline takes; a verdict about the bundle, from
the host or from the bytes, still fails.

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

* fix(mobile): send a hybrid shell recovery through the same gate a start takes

A view failure deleted the host cache and went straight back to the manifest
check on whatever gates the ready session happened to be holding. Gates that
arrive while a generation is on screen are stored without restarting, so after a
reconnect whose status probe failed a ready session carried statusReadable false
and an empty capability list, and the recovery's manifest check walled the host
as bundle-unavailable: terminal, no retry, about a host that never answered.

The gate is now one verdict both entries read, and recovery passes its delete
through it, so an unreadable status lands on the status-unreadable message that
re-arms when a readable gate arrives, and only a readable refusal still walls.

Jinwoo Hong 3160b54c69 feat: real background push notifications for the mobile app (#8129) (#18554)
* feat(cloud): add the mobile push gateway and its contract package (#8129)

A small open-source service that holds the APNs key and FCM credentials and
sends background push to paired phones on the desktop's behalf. Hosts
authenticate with a box challenge and HMAC proof on their pairing key, the
same shape the relay uses, so signed-in and accountless desktops share one
path. Tokens are stored; alert text is held only for the coalescing window.

The contract doc in docs/reference is the source of truth for every wire
shape. The interop test runs the real desktop answerer against a real
gateway-issued challenge so transcript drift fails in CI.

* feat(push): register phones and send background push from the desktop (#8129)

Adds the notifications.remote-push.v1 capability, the registerPush and
unregisterPush RPCs on the mobile allowlist, a gateway client with a cached
session and 401 re-auth, a durable unregister outbox, and a dispatcher that
offers every mobile notification to the gateway after the socket fan-out.
The dispatcher is fire-and-forget with one retry and drops registrations the
gateway reports dead.

Puts agentState on the mobile frame and fixes the #4375 wording so a working
agent is never announced as finished. The relay host-proof code moves onto a
shared envelope module with no behaviour change.

* feat(mobile): background push registration, receive, and settings (#8129)

Fetches the native APNs or FCM token, registers it with every paired host
that advertises the capability, and re-registers on token change. Foreground
pushes are suppressed inside handleNotification against the same seen set
the socket path uses, so nothing shows twice. Taps route by host fingerprint.
One Background notifications switch, off by default, with the disclaimer and
needs-input / finished sub-switches; hidden until a paired desktop is new
enough. Adds google-services.json and the expo-notifications plugin.

* chore(cloud): Terraform and deploy workflow for the push gateway (#8129)

Declares the Cloud Run service, runtime account, secrets, and orca_push
database behind push_gateway_enabled, true only in production. The deploy
workflow is gated like the relay's, deploys with no traffic, probes /ready
and a validate-only FCM send, then shifts traffic. It runs as the shared
production deploy account because the Cloud SQL rollout lease grant is
foundation-owned; its extra authority is three bindings on the push service.
docs/push-gateway.md carries the import commands for the resources created
by hand and the APNs key rotation procedure.

* docs: describe background notifications on the phone (#8129)

* docs: check in the mobile push contract (#8129)

Seven committed files cite it as the source of truth for every wire shape;
docs/reference is allowlisted per file, so add the entry.

* test(push): replay one checked-in host-proof vector on both sides (#8129)

Cloud Verify installs only the cloud workspace, so the gateway suite cannot
import the desktop answerer. Replace the cross-workspace import with a fixed
challenge vector generated from the contract package; the gateway fixture and
the desktop answerer each replay it and must produce the same HMAC. A
transcript drift on either side now fails in that side's own suite.

* fix(cloud): open the push gateway with invoker_iam_disabled, not an allUsers binding (#8129)

The production domain-restricted-sharing policy rejects an allUsers
run.invoker member, which the runbook anticipated. Opt the service out of
invoker IAM the way the relay director already does; the host proof is the
authentication either way.

* docs(cloud): the push.onorca.dev record exists and is hand-managed (#8129)

* fix(push): close review findings in the gateway (#8129)

- Quota reservation takes a per-host advisory lock; READ COMMITTED admitted
  a whole burst past the cap (80/80 without, 60/80 with, against Postgres 16).
- Challenge issuance no longer writes push_hosts; the row lands on proof
  verification. Stale hosts prune after 30 days. Per-IP token bucket on the
  two unauthenticated routes.
- Streaming body limit via hono bodyLimit; a chunked body bypassed the
  Content-Length check.
- registrationIds deduped in the schema; per-host device cap of 64; list
  bounded to its schema.
- Gateway-side challenge TTL is the specified 10 s, not 40 s.
- APNs stream settles on close as well as end/error.

* fix(push): close review findings in the desktop client (#8129)

- A gateway registration the registry cannot persist is enqueued for delete
  instead of leaking a live token.
- Unregister outbox re-reads pending per pass, honours enqueues during a
  drain, and retries with backoff instead of waiting for the next launch.
- Dispatcher batches registrations by 20 rather than starving the rest.
- 401 compare-and-clear; a 401 after re-auth is unreachable; refused
  handshakes and 429s are cached briefly instead of re-handshaking per event.
- Service is stopped on quit.

* fix(mobile): close review findings in push registration and receive (#8129)

- Consent generation guards a register that finishes after the switch went
  off; the host is re-queued for unregister instead of recorded live.
- Foreground pushes seed the watermark before adopting the epoch, so a push
  on a never-connected session cannot wipe a valid watermark.
- aps-environment follows the build via app.config.js; the iOS release
  workflow sets it to production. A bare plugin entry wrote development.
- Pushes the OS showed while closed are marked seen before catch-up replay.
- Token null result is not cached; failed capability probes are retried and
  never block an unregister; coalesced summaries are shown but not marked.
- Unresolvable fingerprint routes nowhere and is suppressed in foreground.
- Android channel ensured at boot; capability hook diffs clients by identity.

* fix(cloud): harden the push deploy workflow and size the gateway to the budget (#8129)

- Roll traffic back on a failed post-shift check; delete a candidate that
  never took traffic; retry the origin probe and the FCM probe.
- Assert Terraform-owned scaling instead of mutating it from the workflow.
- Build before taking the Cloud SQL rollout lease.
- Declare the database pool in Terraform (2 per instance, max 2 instances)
  and add the gateway to the connection budget; the previous default put the
  shared instance 65 connections over its ceiling.
- State plainly that the shared deploy identity's relay authority is inherited.

* fix(push): read the runtime from shared state at push startup (#8129)

Threading the runtime through launchDesktopMode put the launch module one
line over the 300-line lint budget after the rebase.

* fix(push): key the unauthenticated rate limit on the hop Cloud Run wrote (#8129)

Cloud Run appends the connecting peer to x-forwarded-for; the limiter read
the left-most value, which the caller controls, so a forged first hop earned
a fresh bucket per request.

* fix(push): close the final security review findings in the gateway and infra (#8129)

- app.onError logs only the error name and answers a bare 500; hono's default
  handler printed the whole error, and a pg error carries the row in detail
- a second per-IP bucket (240/min) runs ahead of the bearer lookup on every
  authenticated route, so forged bearers cannot spend the two-connection pool
- one live session per host: minting deletes the host's earlier row
- device-less hosts are pruned after 1 h, not 30 d; any keypair mints one free
- notificationId is printable ASCII, since it becomes the APNs collapse header
- the impersonated FCM probe token is masked in the workflow log
- prevent_destroy on the Apple secrets and the orca_push database

* fix(push): close the final security review findings in the desktop client (#8129)

- fetch never follows a redirect: a 307 would replay the host proof and the
  phone's token to whatever origin the redirect named
- registerPush params are strict and the paired identity is spread last
- a per-device bucket (10/min) bounds a phone looping registerPush, which
  costs a gateway write and a synchronous registry write each time

* fix(mobile): close the final security review findings in push receive (#8129)

- a push with no epoch can no longer claim a seq-derived dedup key, in the
  foreground or from the tray; a forged seq:N could otherwise swallow the
  real bell at that seq
- a provider-delivered push with no host catalog, or no fingerprint at all,
  stays unrouted instead of falling back to the hostId its raw data carries

* docs(push): record the ip buckets, session and host retention, and the token-ownership limit (#8129)

* fix(push): apply the schema on an untimed pool and retry statement-timeout aborts (#8129)

Ports the relay's #18722 pattern to the gateway: DDL runs on a one-connection
pool with statement_timeout 0 that is closed before the serving pool opens, and
SQLSTATE 57014 joins the bounded transaction retry path.

* fix: harden mobile push delivery and deployment recovery

* feat: align mobile notification preferences with desktop delivery

* fix: accept variable-length APNs device tokens

Brennan Benson ccd72f5909 Add unified mobile onboarding for session view and notifications (#9478)
* Add a mobile native-chat opt-in so users pick terminal vs chat once

Mirror the notifications one-time opt-in for the native-chat default view.

After pairing, a full-screen modal (modeled on notification-opt-in) lets the
user choose whether supported agent sessions open in the terminal or in native
chat, then persists the choice to the existing orca:defaultSessionView key.

- Expose readDefaultSessionViewPreference() (tri-state; absent key = undecided)
  so the gate can prompt exactly once; loadDefaultSessionView() is unchanged.
- shouldPresentSessionViewOptIn() gates the screen; the home focus effect shows
  it after the notification opt-in.
- Settings -> Native chat toggle (already shipped) remains the recovery path.

Brennan Benson 44686f324c feat(native-chat): add mobile default-view toggle for native chat (#9084)
* feat(native-chat): add mobile default-view toggle for native chat

Adds a per-device "Native chat" setting on mobile (Settings → Native chat)
that controls whether supported agent sessions open in the native chat view
or the raw terminal. Default stays terminal; flipping it on makes eligible
sessions render as native chat, mirroring the desktop default-view control.

- New orca:defaultSessionView preference (loadDefaultSessionView/save).
- Per-tab chat set refactored into a tri-state override map so a session can
  be pinned to terminal or chat regardless of the default; the legacy array
  format migrates to chat overrides on load.
- useMobileSessionViewMode resolves each tab as override ?? default and
  reloads the default on focus so a Settings change applies without remount.
- Toggle/action-sheet builders take an isTabChatView predicate.

64181fdd42 feat(native-chat): native chat view across mobile, desktop, and web (#5824)
* feat(native-chat): add native chat view across mobile

* fix(native-chat): address review findings and CodeRabbit threads

Correctness:
- Restore an independent initial readSession seed and surface initial-drain
  errors as snapshot frames so the chat view can never strand on 'loading'
- Pair mobile tool results to calls by ordinal FIFO (parallel calls no longer
  misgraft results); clear a pending ask only when its own call resolves
- Show a new streaming reply immediately (same-turn suppression, not length)
- Delegate mobile noise filtering to the shared harness-injected classifier
- Admit soft-leaving mobile clients in beginMobileInputFloor (parity with
  mobileTookFloor) so grace-window writes aren't dropped
- Self-heal a stale 'working' status once this turn's reply lands
- Catch RPC rejections in mobile file-open helpers; guard sanitizeToolInput
  key collisions; settle web/runtime transports on unrecognized first frames
  and forward snapshot errors

Perf:
- Throttle the mobile streaming bubble (50ms) so per-part status frames stop
  re-parsing the whole accumulated markdown
- Short-circuit markdown path detection on dot-less or oversized runs
  (quadratic backtracking guard)

UX/minor:
- Wire hold-mode dictation through the native chat composer
- Allow scoped-package (@) paths in file-path detection
- Move caret after mid-text autocomplete insertion; index-prefixed ask option
  keys; single scroll-to-end effect; bounded wait + toast when image attach
  races a resubscribe; count-based pending reconciliation; cache-hit search
  cancels stale debounce; chat-tab toggle wins over in-flight preference load
- Share shouldStepNativeChatAskAnswer between desktop and mobile; import
  block guards/source priority from shared instead of local copies
- Defensive non-positive transcript limits; test strengthening (TTL expiry,
  post-unsubscribe stale frame, lease readiness, filtered console.error)

* refactor(native-chat): share desktop/mobile chat logic in src/shared

Extract the parity-mirrored native-chat modules into shared implementations
both surfaces re-export: ask parsing (registry, parseAskFromStatus,
extractPendingAsk, formatAskAnswer), answer stepping offsets/scheduler, diff
detection/parsing, harness-noise filtering, tool fold/pair/split, and tool
summaries. Removes the hand-synced copies and their stale Metro comments.

Divergence reconciliations take the safer side of each: diffs truncate at
120 lines/32KB everywhere (desktop previously unbounded), tool-run summaries
cap at 3 parts with bounded-depth previews, nameless tool calls are skipped,
and basenames split on both separators.

Also: settle and kill every sibling quick-open pass when one reaches
maxResults (main rg/git and relay git; relay rg already did) so a capped
search cannot leave a scan walking a huge tree; fold window-bounding into
the shared merger's applyAppend; localize the web 'Pair a host' snapshot
error.

* fix(native-chat): address CodeRabbit follow-ups on shared modules

- Attachment lease gate re-checks connection/target/tab after the bounded
  wait, so a tab/host switch or disconnect mid-wait can't send into a stale
  terminal; a moved-away target drops silently like the pre-wait guard and
  only an unrecovered lease surfaces the toast. Adds hook tests.
- extractPendingAsk parses transcript tool-calls through the same
  registered-parser + canonical-shape fallback as live status, so a custom
  question tool that rendered live survives reconnect/replay.
- Direct unit tests for the shared ask parser (FIFO ordering, fallback,
  malformed payloads) and tool-summary bounded preview (depth/collection
  caps, circular refs, basename/command branches).

* fix(native-chat): treat initialLimit 0 as a valid empty window

Both engine guards used truthiness, so an explicit zero limit skipped the
bounded tail reader and fell back to an unbounded incremental read. Latent
only (every caller clamps positive), hardened for consistency with the
tail reader's non-positive-limit handling.

* fix(mobile): native-chat composer lock UX + send-failure feedback

- Distinguish input-lock reasons: transport 'disconnected' shows Reconnecting…
  instead of mislabeling a reconnect as locked-by-another-client
- Guard the composer lock behind a 600ms hold so connState blips / lease
  hand-offs don't flicker the placeholder; unlock stays instant
- Surface a rejected send inline above the composer (a bottom toast hides
  behind the keyboard); auto-dismisses after 4s
- waiting-session hint invites the first message instead of implying the
  agent is still starting

* test(mobile): sync answer-send pacing test to the 500ms advance buffer

Missed in merge 8fe3c391c, which carried main's NATIVE_CHAT_ADVANCE_BUFFER_MS
300->500 (#8568) into the shared stepping module that mobile derives from.

* fix(mobile): restore terminal stream after chat cold start

* fix(native-chat): harden retries, optimistic sends, and file scans

* fix(mobile): deliver AskUserQuestion answers by option number (STA-1860)

Port #8840's fix to the mobile native chat: the Ask card now tracks
per-question option INDICES (+ free text) and the answer-send hook drives
Claude's arrow-navigate selector with buildAskAnswerKeys keystroke groups —
option numbers, next-tab arrows, Enter — paced one selector step apart, instead
of pasting label text that the selector ignores (which silently committed the
default option). Non-Claude agents keep the pasted-label path via the
selection-based formatAskAnswer.

Backcompat: keystrokes are built client-side and written through the EXISTING
terminal.send passthrough with enter:false — the same contract the permission
card already uses — so an older desktop runtime (SSH/relay included) replays
them verbatim; no RPC/contract change in either update order. Free text is
newline-sanitized because terminal.send has no paste framing.

Drops the now-unused formatCompleteAskAnswer from the shared module.

* fix native chat send and runtime races

* fix mobile native chat formatting

* fix(native-chat): mobile empty state matches desktop copy

Mobile showed a single generic line ('Send a message to get started') where
desktop shows a titled two-line empty state naming the agent ('Start a chat with
Claude' + 'Ask Claude to inspect code, explain output, or make a change.'). Align
them from one source of truth so they can't drift again:

- Extract the agent-type label map + formatAgentTypeLabel to
  src/shared/agent-type-label.ts (desktop re-exports; mobile imports).
- Add src/shared/native-chat-empty-state.ts with the canonical English copy;
  desktop uses it as its i18n fallbacks (localization unchanged — en/es/ja/ko/zh
  keys still win), mobile substitutes the agent label and renders it directly
  (mobile ships English only).
- Mobile: render title + subtitle for waiting-session AND ready-but-empty (both
  are 'start a chat'), error copy for errors; keep the loading spinner.

Live-verified on the iOS sim against a pn-dev of this branch. typecheck node/web
+ mobile tsc clean; 30 mobile + 428 desktop/shared native-chat tests green.

* style: oxfmt the empty-state parity test (line wrap)

21a01c7d6b Mobile: worktree-list sidebar for tablet/foldable layouts (#5505)
* Add worktree-list sidebar for mobile tablet/foldable layouts

On wide canvases (tablet/foldable, >=700pt) the per-host worktree list now
renders as a persistent left sidebar with the routed screens (terminal,
source control, review, accounts, tasks) shown in a detail pane to its
right — mirroring the desktop's sidebar + center layout. Phones keep the
existing single-pane stack navigation unchanged.

- Reuse the existing worktree-list screen as the sidebar via an `embedded`
  mode (props for hostId/action, mount-driven fetch since a sidebar is never
  the focused route, hide-sidebar control in place of the back button, and
  open-into-detail-pane navigation that replaces rather than stacks).
- The default host route renders an empty WorkspaceDetailPlaceholder on wide
  layouts (the list lives in the sidebar) and the full screen on phones, so
  exactly one instance mounts either way.
- Hide button collapses the sidebar to give the detail pane full width; an
  elevated reveal tab brings it back.
- Detail-pane screen transitions use `animation: 'none'` while the split is
  active so workspaces swap instantly instead of sliding and flashing the
  screen beneath.
- Drag the sidebar's right edge to resize (clamped 280-560pt, detail pane
  kept >=320pt, tap-transparent so list rows still work); width persists via
  AsyncStorage.

* Address PR review feedback (#5505)

- Clamp the restored/persisted sidebar width against the current window and
  re-clamp when the window shrinks, so a width saved on a larger device can't
  starve the detail pane below MIN_DETAIL_WIDTH. Extract a shared
  clampSidebarToWindow helper reused by load, window-resize, and drag.

cd31cd702d feat(mobile): add terminal text size (zoom) setting (#5388)
* release: v1.4.48-rc.0 [rc-slot:2026-06-05-15]

* release: v0.0.1-rc.0 [rc-slot:2026-06-06-03]

* feat(mobile): add terminal text size (zoom) setting

The mobile terminal fits the desktop's full column count to the phone
width with a CSS scale, which cancels out xterm's raw fontSize — so there
was no way to make text bigger or smaller. Add a persisted baseline zoom
multiplier the WebView applies on top of the fit.

- Settings → Terminal → "Text size": 50%–200% presets.
- Pinch-to-zoom in the terminal snaps to the same presets and persists.
- Per-device display preference; does not change the desktop terminal.
- Extracts the xterm WebView HTML into terminal-webview-html.ts to keep
  TerminalWebView.tsx within its max-lines budget.

* refactor(mobile): make terminal text size reflow columns instead of CSS scaling

Text size now drives the real xterm fontSize rather than a CSS transform
baseline. A larger cell means fewer columns fit the phone width, so the
existing measure -> terminal.updateViewport pipeline resizes the PTY and the
shell rewraps to the new width (and smaller sizes show more columns). Pinch
still snaps to a preset, but now changes the font size and reflows instead of
scaling pixels; the refit hook re-fits the PTY whenever the scale changes.

* fix(mobile): restore terminal touch scrollback (undefined contentWiderThanViewport)

The single-finger touchmove handler gated horizontal panning on
contentWiderThanViewport(), which is never defined — so every one-finger
touchmove threw a ReferenceError before reaching the vertical-scroll code
below it, killing all touch scrolling including scrollback.

Replace the call with the inline overflow check clampPan() already uses
(scrollWidth * getTotalScale() > innerWidth). Vertical scroll now always runs;
two-finger pinch-to-zoom is unaffected. Merged two adjacent var decls to keep
the file under its max-lines cap without a disable.

d17c22c826 feat(mobile): add terminal keyboard autocomplete toggle (#5348)
* release: v1.4.48-rc.0 [rc-slot:2026-06-05-15]

* release: v0.0.1-rc.0 [rc-slot:2026-06-06-03]

* feat(mobile): add terminal keyboard autocomplete toggle

Terminal command inputs disable autocorrect/suggestions and use a
password-class keyboard so the OS never rewrites commands, flags, or
paths. Some users want phone-style typing in the command bar.

Add a Settings → Terminal "Autocomplete & autocorrect" toggle
(persisted locally, default off). When on, the command bar enables
autoCorrect/spellCheck and uses the default keyboard so Android shows
its suggestion strip; iOS drops the ascii-capable restriction. The
direct keyboard-capture input is unchanged — it streams raw keystrokes
where suggestions cannot apply.

* fix(mobile): remount command input when autocomplete toggles

Android caches the IME inputType at mount, so flipping the toggle did
not switch suggestions on until the field remounted.

* fix(mobile): guard autocomplete pref loads against unmount and fast toggle

Address review feedback: the settings toggle's initial load could clobber
a fast user toggle, and the session focus-effect could setState after the
screen unfocused. Both now use a guard flag.

* test mobile terminal autocomplete preference
