Jinwoo Hong 5d13a70ea3 fix(mobile): keep an in-page hop local only when the session's grants cover it (OTA phase C, C2.9) (#21723)
* feat(mobile): carry what each page route declared in init (OTA phase C, C2.9)

The page decides an in-page hop from `init.pageRoutes`, which says which patterns
this shell would render and nothing about what each one costs. So a push kept
local on the strength of the pattern alone runs the target under the opener's
grants — which is how the tasks page is reached from the wide-layout sidebar
without `native.clipboard.write`, and why its copy actions refuse silently.

`init` now also carries `pageRouteGrants`, the manifest's own route/grant pairs,
from the manifest the shell already holds. Optional in both directions: an older
shell omits it and an older page ignores it, and a page that receives none keeps
today's rule. No new frame kind, no cap change, no protocol bump.

The grammar is the manifest's, imported rather than restated
(`MobileWebBundleGrantNameSchema`, now exported for this), so a grant name the
bundle could not have declared cannot reach the page through this field either.
The host validates the pairs before it builds the frame and refuses the session
when they fail, for the reason it already refuses a malformed route: an `init`
the page would reject whole is worse than no session at all.

Two files were at their line ceiling and are split rather than bumped. The pairs
schema moves to `bridge-page-route-grants.ts`, which is read by both the envelope
and the host, so it belonged in one place anyway. In the session reducer the
three sites that each spelled out "patterns, their grants, this route's grants"
become one `routeViewOf`; that is a net reduction and removes the fourth spelling
before it is written.

* fix(mobile): keep a hop local only when the session's grants cover it

The rule the page was using is "the shell would render this pattern", and that is
not the question. Grants are resolved once, from the route the shell opened, so a
push kept local runs the target under the opener's list. On a wide layout the
sidebar renders beside every `/h` route and pushes `/h/<id>/tasks` through this
seam, so from the worktree list, agent history or the files pages the tasks page
ran without `native.clipboard.write` and its copy actions refused with nothing on
screen to say why.

`servedHere` now means served here *and* covered: the target's declared grants
must be a subset of this session's. An uncovered page route is handed to the
shell exactly like a non-page route, and the shell opens it as its own session
with its own grants — which is the mechanism that already exists, rather than a
new one.

Three answers, not two, because an absent field is not an empty one. A shell that
sent no pairs keeps the old behaviour: `null` is "nobody told me", and an older
shell has to keep working. A target the shell lists but names no entry for is
*not* covered — the page cannot justify that hop, so it hands it over rather than
guessing in the direction that loses grants.

This is C3.1's explorer ⊇ preview finding without its pairwise pin: that hop is
covered by this rule and stays local, and the rule scales to the sidebar, which
reaches every route and which no pairwise list can keep up with.

Red first on the two cases only the new rule answers; the other four are the
regression guards and passed before and after. Two whole-session assertions
gained `pageRouteGrants: null`, which is what the reader now returns.

* test(mobile): prove the sidebar hop in a browser, under the session's own grants

The unit tests pin the decision; only a browser shows the control exists, is
reachable at the viewport where the sidebar renders, and that the document does
not move when the hop is handed over.

Four cases on the shared harness, which now forwards `pageRouteGrants` (omitted
when a caller names none, because an absent field is not an empty one and the
page reads the difference).

- Wide, session without `native.clipboard.write`: tapping Tasks posts exactly one
  `navigate` notify, the document stays on the worktree list, and **no new chunk
  is fetched** — which is what says the page did not quietly render tasks under
  the wrong grants.
- Wide, same tap with the grant added: no notify, the document moves to `/tasks`.
  Without this the first case would pass on a page that simply never navigates.
- Wide, shell sending no pairs at all: the old behaviour, local. An older shell
  must not start handing every hop over on a field nobody sent.
- Narrow: asserts the absence rather than a tap. `app/h/_layout.tsx` renders the
  sidebar only on a wide layout, and only that header branch labels its Accounts
  and Tasks controls; the narrow header's are unlabelled pressables. So the hop
  does not exist at that viewport, and `getByLabel('Tasks')` finding nothing is
  the honest assertion. That unlabelled narrow header is a real accessibility gap
  and is not this lane's to fix.

Registered in `pr.yml`'s `mobile_web_app` job beside the other render checks.

* test(mobile): census the in-page hops a session's grants cannot cover

The rule landed in the commit before this one decides each hop; this says which
hops those are, so a route's grants growing — or a new push between two page
routes — shows up here rather than as a verb that silently refuses on a device.

Openers are every page route, not the one that happens to push. On a wide layout
`app/h/_layout.tsx` renders the worktree-list sidebar beside every `/h` route and
its header pushes tasks, which is exactly why a pairwise pin is the wrong shape:
the sidebar reaches everything, so the census has to be the cross product of what
the manifest declares against what the source actually builds.

Targets come from the hrefs the app builds, read out of `mobile/src` and
`mobile/app` and reduced to route patterns, so a hop nobody writes is not pinned
and a hop someone adds is. A presence case asserts the sidebar's tasks push is
among them, because a census that stopped finding hops would go quietly green.

Two hops are pinned as handed off today, both into tasks, which is the only route
declaring more than `navigate` and `storage`. A third case asserts the other half
of the rule on the manifest: a target asking for no more than its opener stays in
the document.

Checked that it discriminates rather than assuming: widening the worktree list's
grants to cover tasks fails the pin, and restoring them passes it.

**No pin was deleted.** The brief expected C3.1's pairwise explorer/preview pin to
be replaced here, but C3.1 is not on this base — `MOBILE_WEB_PAGE_ROUTES` has
three routes and no `files` entry, so there is nothing to remove. When C3.1 lands,
its pin is this census's to subsume.

* fix(mobile): drop an unused import from the hop census

`statSync` was imported and never used; `oxlint` fails it. My error: I committed
the census on a green test run without waiting for lint, the same order mistake I
made earlier in this lane. Fixed forward rather than amended, because the lane
forbids rewriting a commit that exists.

* test(mobile): fold C3.1's pairwise grant pin into the hop census

C3.1 landed while this branch was open, and it brought the case this lane
generalises: the explorer pushes to its own preview, that push stays in the
document, so the preview runs under the explorer's grants. Its pin asserted that
one pair by name.

The census now covers it as a consequence rather than a rule. With the files
routes in the manifest the cross product finds six more hops the session cannot
cover — the sidebar into files from the worktree list and from agent history, and
both files routes into tasks — and it does **not** find explorer → preview,
because the preview declares no more than the explorer. That absence is the
pairwise pin, derived.

So the pairwise block is deleted, with its import. The rest of that file stays:
its external-link seam checks and its clipboard-absence control are about what
the files closure contains, which this census says nothing about.

Checked the extended census still discriminates: granting the explorer
`native.clipboard.write` fails the pin, restoring it passes.

* test(mobile): prove the sidebar hop from a files route, not only the worktree list

The defect is not "the worktree list pushes tasks". On a wide layout the sidebar
renders beside every `/h` route, so the same hop exists from the files explorer,
whose session carries `externalLink` but not `native.clipboard.write`. One opener
proving the rule would have left the general case to inference, which is the
inference C3.1's pairwise pin already made once.

Opened on `/h/<id>/files/<wt>` with the files route's own grants, the sidebar's
Tasks control posts exactly one `navigate` notify, the document stays on the
files route, and no new chunk is fetched.

The harness helper now takes the route and the text to wait for, so a case can
open on something other than the worktree list without a second copy of it.

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

* fix(mobile): make the render helper wait on the text its caller named

The `awaitText` parameter I added in the commit before this one was never wired
into the wait, so it was dead and `oxlint` failed it. The case still passed,
because the files route renders the host name in its sidebar and that is what the
helper was still waiting on — which is exactly the kind of accident a dead
parameter hides.

Third time in this lane I have committed on a green test run before lint
finished. Fixed forward, not amended.

* fix(mobile): carry route grants through the download path

`onManifestRead`'s download branch set `pageRoutes` and `routeGrants` from the
new manifest and dropped `pageRouteGrants`; nothing downstream recomputes it, so
every first install and every OTA update reached `ready` with the default or the
previous generation's pairs. The page then read each target as listed-with-no-
entry and handed off every in-page hop.

`routeViewOf` moves to `page-route-policy.ts`, beside the two functions it calls,
to keep the reducer under its line cap without a bump; its stale neighbouring
comment, which described a filter that moved into it, goes.

Red first: the cold-cache and generation-change cases failed, the cached-hit case
already passed.

* test(mobile): derive census targets from navigation call sites

The reachability filter was inert. Harvesting every `/h/${…}` template caught the
five screens that declare their own mount pathname, two `pathname ===`
comparisons and the route template types, so every declared route was reachable
through its own mount: the pinned table was the all-pairs one, eight hops with
the filter and eight without.

Targets now come from the arguments of `router`/`navigation` `push`, `replace`
and `navigate`, and of `navigateFromHostList`; mounts, comparisons and types are
excluded by construction because they are not navigation arguments. Two real
hops are not written as a literal, so a local binding or a call is followed one
step to the function that returns the pathname: the files explorer is pushed as
`{ pathname: descriptor.pathname }` and the preview as
`push(createMobileFilePreviewHref(...))`. A call site whose target cannot be read
is returned rather than dropped.

Derived patterns go from 11 to 10; the pinned table stays at eight because all
five page routes are genuinely pushed to. What changes is that the filter now
discriminates: deleting the header's two tasks pushes reds the presence case and
drops the four `-> tasks` rows from the pin, where the old derivation stayed
green on the same deletion because `app/h/[hostId]/tasks.tsx` still declared the
pathname. A push added at a real call site appears in the set.

* test(mobile): restore the preview-declares-something guard

The pairwise pin this case replaced asserted the preview declares at least one
grant before asserting the explorer covers them all; without it two empty lists
satisfy the subset check and a route that lost its grants passes.

* docs(mobile): describe the route list under the handoff rule

Two passages described the world before this PR: the explorer's note said the
census pins its pair with the preview, and a closing paragraph left the sidebar's
tasks hop open for a later PR. This is that PR. Covering the preview now buys the
in-document hop rather than making it correct, an uncovered target is handed to
the shell and reopened under its own grants, and the census reads the explorer to
preview relation off this list rather than pinning it by name.

* test(mobile): mirror the manifest's tasks grants in both fixtures

CodeRabbit on #21723: both fixtures declared the tasks route as `navigate`,
`storage`, `native.clipboard.write` while the manifest also declares
`externalLink`, so no covered-session case ever required it.

Both now mirror the manifest's four, and the covered sessions hold them. That
alone does not make an `externalLink`-blind rule fail, since those sessions hold
every grant either way, so the unit suite gains the case that does: a session
holding the clipboard but not `externalLink` must still hand the hop off.
Mutating the rule to treat `externalLink` as always held reds that one case and
no other.

* test(mobile): make a stalled hop name its own cause

Both waits for the hop to land read as a bare 30 s timeout when it does not. The
CI failure that sent this file back was a `TypeError` inside React Navigation
that blanked the document, and it was invisible here because the error
assertions run after a wait that never returns.

The wait now throws with the page's own account: the pathname it stayed on, the
collected page and console errors, the `navigate` notifies posted, the first 300
characters of the body, and every `.js` response since the click with its status.
The response listener records every script answer rather than only the 200s, so a
chunk the navigation waits on can be seen failing; the 200-only list the
no-new-chunk assertions read is unchanged, as is everything the five cases
assert. Kept in this file because no other render file waits on the pathname
moving.

Proved by mutating the rule to hand every hop off: the covered case fails naming
the pathname it stayed on, an empty error list, the notify it posted and no
scripts since the click — which is the handoff signature, distinct from the
crash signature CI saw.

* test(mobile): aim the narrow hop at the control C2.10 named

The narrow case asserted the absence of a labelled Tasks control, which
was true only because the narrow toolbar carried no accessibility props.
C2.10 gave it the wide sibling's role and label, so the assertion was
red on the merge and, worse, the rule this file is about went unproven
on the branch the phone actually presses.

It taps that control now: at 390 px there is exactly one, and the tap
posts exactly one navigate notify for the tasks route while the document
stays on the worktree list and fetches no new chunk. Red first against
the merged header (count 1, expected 0); with the session given
native.clipboard.write the hop goes local and the case reds, which is
what says the assertions discriminate.

* docs(mobile): drop the handoff predicate's contradicted one-liner

The pre-C2.9 summary said the answer is whether this document renders
the target, which is exactly the claim the block comment below it
replaced: the predicate now also requires the target's grants to be
covered. Two doc comments on one declaration, the first of them wrong.

Comment only; the 35 handoff cases are unchanged and green.

* test(mobile): assert which field a route refusal blames

The host builds `pageRouteGrants: <issue>` so a refusal says which of the
two checked inputs failed, and nothing read it: the case counted
refusals, so a host that reported the route's own verdict for a malformed
pair would have stayed green while sending whoever reads the refusal to a
pathname that was never the problem.

The case pins the prefix, a non-empty issue behind it, and that the
diagnostic and the callback carry the same string. The control is an
opener that fails the other way: a malformed route reports its own issue
and does not take this prefix, without which the pin would hold on any
reason at all.

Red first with the field branch dropped from the reason: the prefix
assertion fails and the control stays green.

* refactor(mobile): stop exporting the route filter the reducer stopped calling

`implementedPageRouteEntries` and `implementedPageRoutes` were the
reducer's two ways in before it moved to `routeViewOf`. The entries form
had no caller anywhere afterwards and the patterns form had only this
test, so the module's public surface advertised two functions no product
code reaches. Both are module-local now; the surface is
`matchesRoutePattern`, `pageRendersRoute`, `grantsForRoute`,
`routeViewOf` and the grant list.

The test reads the same list through `routeViewOf(...).pageRoutes`, which
is the reducer's own view of it, so no assertion changed and no export is
kept for a test.

Red first: with both un-exported and the test untouched, seven cases fail
with `implementedPageRoutes is not a function`; routed through the view
all nineteen pass. Still discriminating, as a control: with the grant
filter dropped from the entries helper, four of them fail.

* test(mobile): route the merged haptics cases through the policy view

PR E's two haptics cases arrived with the merge calling
`implementedPageRoutes`, which this branch had already made module-local,
so the merged file was red with `implementedPageRoutes is not defined`
on both of them. They read the same list through `pageRoutesOf`, the view
the rest of the file already uses, so neither assertion changes.

PR E's paragraph named that function for the filter it describes; the
filter now sits in the entries helper the view is built on, so the
sentence says that instead of naming a function the reader cannot see.

Red: the two cases above on the merge. Green: all 21, PR E's two included.

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

* test(mobile): mirror the haptics token in every handoff fixture

PR E put `haptics` on all five manifest routes, and these fixtures still
carried the pre-E grant lists: tasks with four grants where the manifest
now declares five. A fixture that is short the same token on both sides
of the subset check agrees with the rule by accident, and would have gone
on agreeing after the token stopped being universal.

The pairs mirror the manifest now, and each session carries what its
opener route would actually be granted, since the host narrows a route's
declared grants to what the shell implements and the shell implements the
token.

Red first, with the token added to the pairs alone: the two covered-hop
cases flip to handed-off, `stays in this document when the session
already covers the target` and `keeps the hop in the document when the
session covers tasks`. Green once the sessions carry it, 35 and 5.

The hop census needed nothing: it reads `MOBILE_WEB_PAGE_ROUTES` itself.
Measured there, all 5 routes declare the token and it is the missing
grant in 0 of the 8 uncovered pairs, so it cannot decide a hop and the
rule still reads only `pageRouteGrants`.

* test(config): count C2.9's two bridge modules in the session route closure

#21908 recorded this pin at 4,324 for the haptics notify module. C2.9
adds two more that the same closure reaches: the page-route-grants schema
and the manifest contract whose grant grammar it imports rather than
restates, both pulled in by `bridge-envelope.ts`, which the page reads to
parse `init`.

Named in the docstring beside #21908's sentence rather than folded into
its number, because the three modules arrived from two PRs and a single
count with one reason invites the next author to assume the rest.

Red first against 4,324: expected 4,326. Measured on this head, not
inferred -- a control worktree at pristine main gives 4,324, so the two
are this branch's.

Neil c74ba15f31 fix(claude): stream the provider history window (#21742)
* fix(claude): stream the provider history window

An oversized Claude transcript made restart reconciliation unresolvable:
readClaudeProviderHistoryWindow buffered the whole project JSONL, so a file
past the 16 MiB bound returned an inconsistent boundary — the one answer the
reconciler can never act on — and a file just under it still went resident.

The window now reuses the streaming primitives from #21024 instead of a
whole-file read. Two bounded passes run over ONE pinned descriptor and size:
the graph pass builds the branch proof (uuid/parentUuid only), and the replay
pass hands back the first record per chain uuid, fingerprinted on the spot. A
repair appended mid-read re-runs BOTH passes at the grown size, so the replay
can never read bytes the proof did not vouch for. The 16 MiB bound survives as
a per-record framing limit, which is the only remaining way the source could
become resident.

claude-transcript-branch-proof.ts is split at its real seam to stay under
max-lines: claude-transcript-branch-graph.ts is what the rows mean as a graph,
and the proof file is which bytes the graph gets to see.

Peak heap over a 252 MiB transcript: 542 MiB whole-file, 53 MiB streaming —
and flat at 53 MiB for a 63 MiB transcript, where whole-file took 136 MiB.

* fix(claude): fail closed when the ancestry walk misses the anchor

The source-budget anchor test filtered on `"latest"`, which also removed the
last-prompt marker. The transcript was unprovable, so the empty window and
single pass it asserted came from an INCONSISTENT verdict, not from the
leaf-equals-anchor path. Filter the record only and assert the boundary.

`ancestryChain` returned [] both for "the leaf IS the anchor" and for a walk
that fell off the graph. The first means nothing followed the anchor; the
second means we never looked. Throw on the second, so the window reports an
inconsistent boundary rather than non-delivery.

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

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

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

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

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

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

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

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

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

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

* feat(mobile): render mermaid in the page

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

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

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

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

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

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

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

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

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

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

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

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

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

Measured, at 14 routes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The control is the same document for a diagram that parses: a height,
not `error`, and one SVG.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Pablo Werlangandorca-agent 646fa3645f fix(opencode): attribute shared-server sessions to their panes (#21577)
* docs: allow-list opencode tool-readout follow-up note

* fix(opencode): attribute shared-server sessions to their panes

The v2 shared server stamps every hook post with its own frozen pane,
so all panes' status lands on the starter pane (#21359).

- shared: session->pane registry plus ingest-time envelope rewrite;
  bound sessions resolve to their real pane, tab and live launch token
  before disposition, unbound sessions keep the stamped identity.
- main: binder poll (SQLite session store, PTY-registry pane snapshots,
  argv-aware client sweep) with directory-containment plus
  client-lifetime correlation; 60s loop plus debounced SessionStart kick,
  wired into the hook server lifecycle.

* fix(opencode): newest-wins pane dedupe, macOS private/tmp normalization

Live verification against the dev instance found two binder gaps: remint
rows for one pane counted as an ambiguous tie, and /tmp vs /private/tmp
spellings never met on macOS.

* fix(opencode): review fixes — newest-wins worktree, drop dead constant

- applyBinderOwnerships now overwrites per-pane worktree, matching the
  round's newest-wins pane dedupe; a remint's live row wins over a stale
  row (pinned by test).
- remove the unused OPENCODE_CLIENT_PRE_CREATE_WINDOW_MS export and the
  nowMs residue from clientCouldCreate.
- give the per-pane launch-token cache its own named cap constant.

* fix(opencode): address thread review — cursor, native table, tokens, lifecycle

- composite (time_created, id) store cursor advanced past handled rows
  only, so same-millisecond pagination and full unbound maps no longer
  drop sessions silently.
- Windows sweep reads the native process table instead of forking
  powershell.exe; quote-aware argv parsing on both platforms.
- directory keys via normalizeRuntimePathForComparison (Windows
  case-fold, POSIX backslash literals) plus narrow macOS /tmp|/var|/etc
  aliases and lexical dot-segment resolution.
- bound sessions always take the stored pane token (never the frozen
  stamp); token tracking runs after resolution.
- binder generation guard discards post-stop rounds; first round runs
  immediately at loop start.

- move the tool-readout note out of this PR for its own branch.

* fix(opencode): second review round — executable field, worktree scope, round lifecycle

- POSIX sweep reads comm= alongside args= and classifies on the
  kernel executable name, so unquoted install paths with spaces no
  longer split argv[0] and reject the client; Windows rows carry the
  native table name. Degrades to argv[0] when comm is unavailable.
- bound sessions take only the binding's worktree (never the stamped
  pane's), so a worktree-less binding cannot file a row under the
  wrong worktree.
- the binder generation is captured before the round body and the
  running flag clears only for the current generation, so an obsolete
  post-stop round cannot admit an overlapping round.

Jinwoo Hong e476193bf5 chore(relay): bound the shadow health gate and apply a pending backend update on resume (#21865)
* fix(relay): bound the same-cap shadow gate and apply a resumed backend update

Two findings both adversarial reviews of tonight's merged set agree on.

The report-only shadow health gate (#21849) had `continue-on-error: true` but
no step timeout. That bounds the step's contribution to the job outcome, not
its clock. Its reads are serialised, and a failure that answers nothing slowly
— an expired credential, a project-wide Logging 429 storm — makes every read
cost its full 3 x 60 s retry budget, so the cost scales with the roll window:
roughly 8S + 2 reads for S ten-minute sub-windows. A 40-minute window is about
34 reads, or 108 minutes, against the job's `timeout-minutes: 75`. A cancelled
job cannot be absorbed by continue-on-error, fires the failure-gated cleanup
isolation on an already-restored cell, and stops the strict next-cell chain.

Give the step `timeout-minutes: 5` and the artifact upload `timeout-minutes: 2`.
A timed-out step is a failed step, which continue-on-error covers, so the job
stays green. Inside the script, stop reading after an overall four-minute
deadline and report the remaining checks unverified, so the normal outcome is a
written verdict rather than a killed process; the step timeout is then only for
a hung process. The census test pins both timeouts and that the deadline leaves
the step time to write its verdict.

The resume branch (#21860) accepted `changes == 0` with a non-empty
`backendUpdate` as complete and applied nothing, so a resumed cell silently
kept the 300-second drain and no request logging behind a green resume. That
shape means the template and MIG are converged and only this cell's reviewed
backend update is left, so apply the saved resume plan — the validator has
already bounded it to this cell's backend and neither attribute restarts an
instance — then continue as converged. Template-and-MIG drift still applies
nothing, which is what a resume means, and a stranded cell's explicit MIG
replace is unchanged.

Claude-Session: relay-same-cap-gate-timeout-and-resume

* fix(relay): raise the shadow gate bounds clear of a healthy gate's read time

A healthy gate is already minutes of serial reads on the 2-vcpu runner, so a
four-minute deadline would report unverified tails on ordinary days and stop
the shadow roll measuring the comparison it exists for. Raise both together:
the step to eight minutes and the script's own deadline to seven, keeping the
census pin that the deadline leaves the step room to write its verdict. The
job budget is unaffected: a ~14-minute cell plus eight is well inside 75.

Jinwoo Hong 2524737ef0 chore(relay): apply the cell backend drain and request-logging settings inside each same-cap wave (#21860)
* chore(relay): target each cell's backend service from the same-cap job

The 60 s connection drain timeout merged in #21848 has no safe apply path.
A root plan scoped to the backend services alone still pulls every
`google_compute_instance_template.relay_gce_cell` in as a dependency, and
standing image drift turns all 29 into replacements, so applying it would roll
the fleet at once.

Add `google_compute_backend_service.relay_gce_cell["${TARGET_CELL_ID}"]` to
both plan invocations in the per-cell same-cap job, next to the template and
MIG it already targets, and teach the reviewed plan validator to allow exactly
one extra change: an in-place update of that one cell's backend whose only
changed attribute is `connection_draining_timeout_sec`, landing on the
constant `validate-relay-asia-topology-plan.mjs` exports. Any other attribute,
any other resource, or a backend for another cell still fails the validator.

The accepted update is reported as `connectionDrainUpdate` and kept out of
`changes`, so the apply step's stranded branch and the resume step's drift
branch keep reading the template-and-MIG count they were written against; the
resume branch additionally accepts a plan whose only pending change is that
drain update, which restarts nothing.

Claude-Session: relay-same-cap-targets-cell-backend

* fix(relay): also let the same-cap wave apply this cell's LB request logging

A read-only production plan for production-gce-c7 showed the live US cell
backends carry no `log_config` at all, while relay-gce-cells.tf has declared
`log_config { enable = true, sample_rate = var.relay_gce_cell_log_sample_rate }`
on every cell backend since the Terraform root landed in 3eec77c11a (#18413).
Nothing has applied it because every production apply since is a per-cell
targeted plan that names only the template and the MIG.

So the real canary plan's backend moves two paths, not one:
`["connection_draining_timeout_sec", "log_config.0"]`. The drain-only validator
rejected exactly that plan, which would have stranded the cell mid-wave after
the drain had already started.

Accept both, each optional, for this cell's backend only: the drain landing on
RELAY_CELL_CONNECTION_DRAIN_SECONDS, and a log_config of exactly one block with
`enable = true` and `sample_rate` equal to RELAY_CELL_LOG_SAMPLE_RATE, the
declared default of a variable no environment file overrides. Any third path,
a different sample rate, disabled logging, another cell, or a replacement still
fails. The accepted paths are reported as `backendUpdate`, which the resume
branch now reads instead of the drain-only flag.

Verified against the real production plan: the masked, three-target plan for
production-gce-c7 contains exactly that cell's template, MIG, and backend
service and nothing else, and this validator returns
`{"changes":2,"backendUpdate":["connection_draining_timeout_sec","log_config.0"]}`.

* fix(terminal): let Shift+middle-click paste in mouse-tracking panes

Follow-up to #21834 (issue #21762). That fix arms the native-paste
suppression window for every terminal middle-click, then returns early
when the pane is in mouse-tracking mode so the TUI performs the paste
from the forwarded mouse report.

xterm's SelectionService.shouldForceSelection deliberately withholds
that report for a shifted click (Option-click on Mac), so the TUI never
pastes. With the native follow-up paste now suppressed as well,
Shift+middle-click in Claude Code, Codex, and other tracking TUIs pasted
nothing at all. Previously Chromium's native paste was the one paste.

Mirror xterm's platform rule: when the click's modifier forces
selection, fall through to Orca's own paste-to-PTY path (stop
propagation, focus, paste) exactly as in a non-tracking pane. The
auxclick handler gates stopPropagation the same way.

Jinwoo Hong 5b8ac36f41 chore(relay): add a report-only post-wave health gate to the same-cap cell job (#21849)
* feat(relay): report a post-wave health verdict on each same-cap cell, without gating on it

After a same-cap cell finishes rolling, an operator reads five things by hand
before dispatching the next cell: director 503s against the same clock hour a day
and two days earlier, whether the cell's new container announced its listener and
has stayed up, the cell's own pool pressure, the asia-east2 pool trio, and Cloud
SQL FATALs. This runs those same reads automatically and records PASS / WARN /
WOULD_BLOCK with its numbers, so its calls can be compared with the operator's
over a full roll before it is ever allowed to stop one.

It cannot fail a cell in this change. The script exits 0 on every verdict, and
the step is continue-on-error, so even a crash stays off the job's outcome and the
failure failsafe cannot fire on anything it observes. It also runs after the
restore, so no cell waits on it to go back into admission.

Cloud Logging returns only --limit entries and says nothing when it truncates, so
every count is split into sub-windows of ten minutes and a sub-window that comes
back at the limit is reported unverified rather than as a count. Windows are
always explicitly bounded: --freshness does not bind on these logs.

Claude-Session: https://claude.ai/session/ced32ebb-7155-4413-adad-1eccd14c2010

* fix(relay): bound the shadow gate's cell reads at the apply start and cap every read

Four fixes from review, all in the report-only shadow health gate.

The boot search opened at apply-completed-at, which is stamped after
`terraform apply` and `wait-until --stable`. The new container announces its
listener while the MIG is still converging, so that bound is already past the
announcement it looks for and a healthy roll read as would-block. The job now
stamps apply-started-at immediately before the apply, and the boot search opens
there; apply-completed-at is kept, recorded rather than judged, so an operator
comparing verdicts can see apply time next to boot time.

The crash query started at the newest listener timestamp, which erased any crash
before it. A crash-restart loop ends with an announcement that looks like a clean
boot, so that is exactly the case it hid: against production, the 2026-09-20 c28
crash at 20:18:10 was dropped because the listener landed at 20:18:27. It now
runs from the apply start, still scoped to the instance id the listener
identified, and that crash is counted.

A runtime-metrics read that came back at its 500-entry limit fed judgePool as
though it were a complete sample run. A truncated run has holes and the
consecutive-sample rule reads a hole as a recovery, so it now reports unverified.

gcloud reads had no timeout. continue-on-error bounds the job's outcome but not
its clock, so a stalled read could have spent the rollout's remaining minutes.
Each read now gets 60 s and a timed-out read is just a failed read.

Claude-Session: https://claude.ai/session/ced32ebb-7155-4413-adad-1eccd14c2010

* test(relay): require each shadow-gate stamp's presence before asserting its order

The ordering assertion used indexOf, which answers -1 for an absent stamp, and
-1 precedes every real offset. Deleting the apply-started-at line left the test
green, so the census could not see the fix it was written to pin.

Each stamp's presence is now asserted first, with a message naming the stamp and
the step, and presence is judged inside the step that owns the stamp rather than
anywhere in the file: a stamp written into a neighbouring step records the wrong
instant but would satisfy a whole-file match.

Control-run against a scratch copy of the job. Deleting drain-started-at,
apply-started-at, or apply-completed-at each reds with its own message, and
moving apply-started-at after terraform apply reds on the ordering assertion, so
presence and order both fail independently.

Jinwoo Hong 4f839cc8c9 chore(relay): cut the cell LB connection drain to 60 s and allow ten-cell same-cap batches (#21848)
* perf(relay): cut the cell LB drain to 60s and widen the same-cap batch to ten cells

Two independent sources of relay roll wall clock, neither of which protects a
host:

1. `connection_draining_timeout_sec` on the per-cell backend services was 300s.
   The same-cap job drains every host off the cell to a restart-safe condition
   before Terraform runs, so the LB drain only ever covers a host still
   mid-handshake. Measured 2026-09-16 over ten same-cap cell jobs, it sat as
   ~5m55s of dead time between `Apply complete` and the old VM powering off,
   inside an 8.5-minute `wait-until --stable` step. Now 60s, and pinned in the
   topology `check` block beside the other fixed-one invariants.

2. The same-cap wave capped a batch at four cells, so a 22-cell roll needed six
   batches, six single-use monitor gates, and a human handoff per batch. The
   wave workflow now declares cell_1..cell_10 with the identical serial shape
   and chaining, and the validator accepts two to ten.

The shared wave-index rule (`relay-monitor-evidence.mjs` and the relay-ops
preflight CLI) widens from 0-3 to 0-9 so the later cells can present the same
evidence; each job workflow keeps its own narrower range, so the capacity wave
stays at four. Cells remain strictly serial, one at a time behind the rollout
lease, each with its own live preflight.

Claude-Session: https://claude.ai/session/relay-roll-drain-timeout-and-batch-cap

* fix(relay): align the Asia topology plan validator with the 60s cell drain

`validate-relay-asia-topology-plan.mjs` rejected any Asia backend whose
`connection_draining_timeout_sec` was not 300, and
`cloud-deploy-relay-asia-topology.yml` targets
`google_compute_backend_service.relay_gce_cell["<cell>"]` per cell. With the
Terraform local at 60 that workflow would have failed its own plan review.

The validator's two restated topology values are now named exports, and a new
census test reads `relay-gce-cells.tf` and equates three statements of each:
the `relay_gce_topology` local, the topology `check` assert that pins it, and
the validator constant. Terraform cannot export a local to JS, so reading the
source is the only way to stop them drifting; the test was confirmed to fail
when the local alone is moved back to 300.

Repo-wide grep finds no other pin of the drain value.

Jinwoo Hong ec82173130 feat(mobile): mount the terminal document in the page over its own modules (OTA phase C, C7.5) (#21809)
* 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.

* 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.

* 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
pending surface are declared and assigned only here and stay module locals.

Counts: qualified 7, scope declarations 1, rebindings 4, braced bodies 2,
unbound catches 2, number properties 0.

* 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.

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

* 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.

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

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.

Counts: qualified 49, scope declarations 0, rebindings 15, braced bodies 11,
unbound catches 0, number properties 0.

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

* refactor(mobile): extract the terminal mouse-click-drag group into a module

The eleventh named group. The escape byte and both SGR mouse modes join the
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.

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

* 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.

* refactor(mobile): extract the mouse-mode DECSET scan slice into a module

The first of the thirteen inline slices. Both control-sequence introducers,
the straddling scan tail and all three mode fields are declared by the
runtime-state slice, which is still document text, so they move onto the scope
with their declarations left where they are.

Counts: qualified 20, scope declarations 0, rebindings 10, braced bodies 9,
unbound catches 0, number properties 0.

* refactor(mobile): extract the terminal message-bridge slice into a module

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.

* refactor(mobile): extract the terminal term-observers slice into modules

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.

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

* 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,

* 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 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.

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

* 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,

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.

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

* 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:

  terminal-webview-html/write-queue.test.ts -> document/write-queue.test.ts   34
  terminal-webview-theme-injected.test.ts   -> terminal-webview-theme.test.ts 14

  terminal-webview-engine.test.ts                                             49

Pattern changes, old -> new.

terminal-webview-reflow.test.ts
  if (!term || isAlternateBufferActive()) return;
                        -> if (!scope.term || isAlternateBufferActive()) {
  term.resize(nextCols, nextRows);        -> scope.term.resize(nextCols, nextRows);
  var wasAtBottom = buffer.viewportY >= buffer.baseY;
                        -> const wasAtBottom = buffer.viewportY >= buffer.baseY;
  term.scrollToBottom();                  -> scope.term.scrollToBottom();
  if (nextCols === term.cols && nextRows === term.rows) return;
                        -> if (nextCols === scope.term.cols && nextRows === scope.term.rows) {

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.

  query-reply             terminalDataRepliesEnabled = true       -> query-reply test, 2 failed
  path-tap                const parsed = parsePathLineCol(...)    -> path-tap test, red

  osc-link-tap            return parsePathLineCol(value)          -> url-tap test, 1 failed
  terminal-theme          scope.term.options.minimumContrastRatio = ...
                                                                  -> theme test, 4 failed
  write-queue             scope.writeQueue[scope.writeQueueHead] = undefined
                                                                  -> write-queue test, 4 failed

`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.

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

* 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.

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

* 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`.

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

* 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`.

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

* 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.

Golden: 106116 -> 108134 bytes; payload 724150 -> 726168, sha256

* 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.

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

* 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.

Jinwoo Hong eb6068a434 fix(relay): stop a terminated checked-out PostgreSQL client from killing the cell (#21840)
pg-pool removes its own `error` listener when it hands a client out
(pg-pool@3.14.0 index.js:344) and only reattaches it in `_release`
(index.js:385). Between acquire and release the client therefore has no
`error` listener, so when Cloud SQL terminates that session mid-statement
the emit becomes an unhandled 'error' event and the process exits.
`absorbPostgresIdleClientErrors` cannot see it: pg-pool routes to
`pool.on('error')` only from the idle listener.

Attach a per-checkout `error` listener in the one seam every relay
checkout passes through, log a single warn line, and release the client
with the error so pg-pool destroys it instead of pooling a dead
connection. The listener is removed on release so it cannot accumulate.
The in-flight query still rejects, so existing failure reporting and the
transaction retry ladder are unchanged.

* fix(terminal): arm native-paste suppression on middle-click in mouse-tracking TUIs (#21762)

Orca's own middle-click paste path bailed out entirely whenever the pane was
in mouse tracking mode (Claude Code, Codex, ...), skipping preventDefault()
and never arming the #8993 native-paste suppression window. Chromium's
native Linux middle-click paste then landed unsuppressed alongside the TUI's
own PRIMARY paste from the forwarded mouse report, pasting the selection
twice.

Split pane lookup from the tracking-mode gate: any terminal pane target now
arms suppression and blocks the native paste, while only the paste-to-PTY
(and the propagation stop that would swallow the click before xterm can
report it) stays gated on mouseTrackingMode === 'none'.

Jinwoo Hong 68b11282a5 fix(relay): let the rehome evidence parser read a line the director grew (#21823)
The enable workflow reads the director's `[orca-relay] regional rehome
inventory` line out of Cloud Logging and pins the whole line with one regex.
Adding `hostNotArrivedLast24Hours` in #21813 made every healthy line stop
matching, so "Read fresh aggregate completion and abort evidence" threw
"no aggregate regional rehome inventory evidence" and the fail-closed step
disabled the durable switch at control generation 26.

The parser now requires the six original fields and tolerates further ones
in any order. Extra fields stay fenced by value shape rather than by pinning
the whole line: a field must be a bare name and a non-negative integer or
`none`, so `hostId=someone` is still not a counter and cannot ride along.
An absent count reads as null, not zero, because an older director not
reporting leaks is not the same as reporting none.

`hostNotArrivedLast24Hours` and `oldestActiveAgeMs` now reach the evidence
JSON and the operator step summary.

Two guards close the chain, each verified to fail on the regression it
exists for: a census in the relay package feeds the real formatter's output
to the real parser, and a script-side test pins the parser's output to the
fields the workflow summary renders.

Jinwoo Hong fa0010e8d6 fix(relay): abort rehomes whose host never arrived, without disabling the switch (#21813)
A regional rehome whose host went offline right after accepting the move
left its migration row open forever: the target had registered it, the host
held nothing on the source, and the completion sweep could never finish it.
Eight such rows filled REGIONAL_REHOME_CONCURRENT_LIMIT and every later
candidate came back deferred, silently, for 21 hours.

The only sweep that touched them fires at 24 hours and also sets
enabled = 0 on the durable control, so the first leak to age out would have
turned rehoming off, repeatedly.

Adds a director sweep that rolls such an attempt back to its source after
one migration lease, with abort_reason = 'host_not_arrived', reusing the
existing rollback (assignment epoch bump back to the source, lease removal,
superseded target reservation release) and leaving the switch untouched.
The 24-hour sweep keeps its disable as a last-resort latch.

The source cell now names why it deferred, on a new optional response field,
and the director stops walking its candidate page on a deferral no later
candidate can pass. Each poll that dispatched logs one summary line.

Jinwoo Hong 9fbdfc592c refactor(mobile): generate the terminal WebView document from typed modules (OTA phase C, C7.1) (#21804)
* 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
pending surface are declared and assigned only here and stay module locals.

unbound catches 2, number properties 0.

* 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.

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

* 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.

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

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.

Counts: qualified 49, scope declarations 0, rebindings 15, braced bodies 11,
unbound catches 0, number properties 0.

* refactor(mobile): extract the terminal mouse-click-drag group into a module

The eleventh named group. The escape byte and both SGR mouse modes join the
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.

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

* 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.

* refactor(mobile): extract the terminal term-observers slice into modules

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,

stays a module local.

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

become real imports.

The slice also carries `disposeTermObservers` and `extractMouseModeScanTail`,
which belong to other concerns but sit here because emitted-document order

The observer disposal keeps its guard-as-expression form behind a line-scoped

* 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,

* 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.

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

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,
unbound catches 2, number properties 0, shorthand properties 0.

* 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.

* 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:

  terminal-webview-theme-injected.test.ts   -> terminal-webview-theme.test.ts 14

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.

* 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.

* 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(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.

Jinwoo Hong d86d5cbbee fix(mobile): settle browser dialogs on the stream that reports them, map taps through the page scale, and sweep the frame budget on the real encoder (OTA phase C, C6.7) (#21799)
* fix(browser): settle a page's dialog on the stream that reported it (OTA phase C, C6.7)

Chromium hands `Page.javascriptDialogOpening` to one CDP session and takes the
answer only from that session; a client attaching afterwards is told `No dialog
is showing`, and every renderer-bound command it sends first blocks behind the
dialog it was sent to clear. Measured on Chromium 1217, 2026-09-20.

`browser.dialogAccept` and `browser.dialogDismiss` went to the agent-browser
bridge, which is always a later client, so the reply never reached
`Page.handleJavaScriptDialog`: the page stayed blocked and its next dialog
never opened. The screencast is the session that reported the dialog, so it is
the session that answers it. With no stream live on the page the bridge path is
unchanged.

No RPC shape changes.

* fix(mobile): keep the browser dialog card until the page takes the answer (OTA phase C, C6.7)

The card was cleared on the press, before the reply was sent. A page blocked on
a dialog is still blocked until the host settles it, so the pane reported an
answer the page never got and left the user looking at a stream nothing could
move. The host's `dialogClosed` is what says the page took it, and that already
clears the card.

The port-pair case runs the pane against a host that only moves the page when
the dialog is answered: alert, OK, the card stays while the reply is in flight,
then the confirm raises its own card and resolves with the button's value.

* fix(mobile): map a tap through the page scale the frame was painted at (OTA phase C, C6.7)

Mobile view emulates a phone viewport, and a page with no `<meta name="viewport">`
lays out at Chromium's 980 px default and is scaled into it. The frame metadata
says so: `deviceWidth` stays the emulated width and `pageScaleFactor` carries the
ratio. The browser's input commands take page CSS pixels, so a tap sent in the
frame's own device space landed at that fraction of the aim — 41% on the phone,
which is how the C6.6 proof found it.

The frame geometry now carries the scale the frame was painted at, and both the
tap map and the finger-sized click radius go through it. Measured on Chromium
1217, 2026-09-20: `scrollOffsetX/Y` must not be added — the frame is the visual
viewport and the commands take viewport-relative coordinates, so a click sent at
`device / scale + scrollOffset` landed a screenful past its target while
`device / scale` hit it. Web view mode reports a scale of one and is unchanged,
and so is a frame whose metadata carries no usable scale.

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

* test(mobile): sweep the frame budget on the encoder the product runs (OTA phase C, C6.7)

The C6.5 sweep encoded through `canvas.toDataURL` while the pane's frames come
from `Page.startScreencast`, so the certification and the product were measuring
two encoders. The sweep now drives the screencast, over the same 143 viewports
and the same noise, through the same real shell.

The two encoders agree to within a thousandth of a byte per pixel, and the
screencast is the cheaper of them: across the 111 viewports the budget fits it
measured 0.543986 to 0.552964 bytes per pixel, against 0.54470 to 0.55351 from
`toDataURL`. `WORST_CASE_JPEG_BYTES_PER_PIXEL` stays 0.56, now stated as the
screencast maximum plus 1.3%.

So the encoder is not what made the C6.6 device proof drop 1 frame in 41 at
402x593 with the budget on. That frame needs about 0.5649 bytes per pixel, above
everything either sweep has seen, and nothing here reproduces it. The docstring
records that rather than folding it into the constant.

The frame is emulated at one device pixel per CSS pixel and the page carries a
viewport meta: headless Chromium composites at the DIP surface size whatever
`deviceScaleFactor` says, so without both the canvas is scaled into the frame,
the noise averages away and the sweep reads about 0.12 bytes per pixel.

Also records what C6 ruling 1 costs, in the pane's docstring: "never dark" holds
only for a page that produces some frame that fits. With every frame over the
cap the pane sits on its busy spinner over an unpainted viewport, which is the
budget's reason for existing. No code change for that.

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

* test(mobile): wait on the double buffer's flip, not on a digest (OTA phase C, C6.7)

The render check waited for some painted layer to carry a digest other than the
previous frame's. `applyFrame` writes the next frame's URI onto the hidden layer
as soon as the frame lands and only flips the opacity once the decode resolves,
so that predicate is true before the frame is on screen.

Measured with a MutationObserver over the style writes, 2026-09-20: the URI
landed 80.7 ms after the emit and the flip at 85.7 ms, a 5 ms window in which
the wait returns and the visible layer is still the previous frame. The check
usually outran it by the round-trip it spends reading the layers back, which is
why it failed once in CI (#21790, d1d9a59288) with the second frame's digest
equal to the first's and no console errors.

Both cases that used that predicate now wait on the flip itself: the visible
layer must become the other one, which is one opacity write at
`settleBrowserFrameLayer` and the behaviour under test rather than a proxy for
it. Asserting the exact layer rather than any change keeps a pane with nothing
visible from reading as a flip. The digest assertions stay, as the content check
the wait no longer stands in for.

With `settleBrowserFrameLayer` stubbed to skip the flip the case fails on the
wait, so it is still an oracle for the behaviour and not only for the timing.

* fix(browser): one dialog reply shape, and no dialog outliving its stream (OTA phase C, C6.7 round 1)

Round 1 findings 2 and 4.

The reply body forked: `{}` when a pane was streaming the page and the
agent-browser payload when one was not, so `orca browser dialog accept --json`
printed a different body depending on whether anyone happened to be watching.
Both paths now answer `{ accepted: boolean }`. The bridge's own body is not
forwarded, because it is whichever JSON that agent-browser version prints, which
is the thing a caller cannot rely on. Pinned by asserting the two paths answer
the same value.

A replacement stream can meet an open dialog: the last subscriber leaving stops
the page's session, and a later subscribe builds a new one, which is what
backgrounding and foregrounding the phone does. Measured on Chromium 1217,
2026-09-20, with the dialog up: detaching the session that reported it does not
complete, `Page.enable` on a fresh session does not complete, and
`Page.handleJavaScriptDialog` on it answers `No dialog is showing`. So carrying
`dialogOpen` across would report a success the page never got, and the
replacement's own start would hang before it could try.

The stream therefore dismisses a dialog still open when it stops, before
`Page.stopScreencast`, so no session is ever replaced with one outstanding.
Dismissing is the conservative answer for every dialog type including
beforeunload, and the automation path has taken it since `cdp-debugger-events.ts`.

* fix(mobile): say when a dialog answer did not land, and drop the sweep's inert emulation claim (OTA phase C, C6.7 round 1)

Round 1 findings 1, 3 and 5.

The sweep's `deviceScaleFactor` is inert and the docstring claimed otherwise.
Headless Chromium composites at the DIP surface size whatever the factor says,
so the sweep returns the same 0.543986 / 0.552964 to six decimals at 1 and at 3;
`Emulation.setDeviceMetricsOverride` is there to size the surface and nothing
else. What actually guards the measurement is the document's viewport meta,
without which the page lays out at 980 px, the canvas is scaled into the frame
and the noise averages away. That is no longer left to a comment: a case now
measures the same frame with the meta removed and reads under 0.3 bytes per
pixel, which is what proves the sweep's 0.5 floor is the thing that would catch
it.

The card cleared only on `dialogClosed`, but the request still suppressed its
error and timed out at 5 s, so a refused or timed-out answer left the modal up
with nothing said and a button that looked dead. A failed answer now marks the
open card, which keeps its buttons live for the retry. The updater is what stops
a late failure reopening a card the page has since closed.

The "never dark" note moves onto the component it describes, from the detached
block it was sitting in between the imports and the props type.

* fix(mobile): scale the wheel, answer a dialog once, and capture the sweep after the paint (OTA phase C, C6.7 bots)

Three bot findings on 6341321f44.

The wheel converted screen deltas with the frame fit and the zoom and left the
page scale out, so a flick on a page with no viewport meta delivered about 41%
of the scroll asked for — the same omission the tap had, one call site over.
Both call sites now go through one scale, named for the three factors every
screen-space quantity this pane sends has to carry.

`dialogOpen` stayed true until `Page.javascriptDialogClosed`, so two answers in
flight both sent `Page.handleJavaScriptDialog`. Chromium takes one per dialog:
the second is refused, or settles the page's next dialog unseen if it has
already been raised, and the rejection came back out of the RPC. One settlement
promise per dialog now, handed to duplicate callers, cleared when the dialog
closes or when the command fails — and only by its own dialog's generation, so
a late failure cannot disarm the next dialog's answer. The stop path reuses a
settlement already on its way rather than adding a second command. On the pane
the card's buttons go dead while an answer is in flight, keyed on the token of
the answer that armed them, so a reply landing after the page moved on writes to
neither card.

The sweep painted its noise before `Page.startScreencast` and accepted whatever
frame the deadline left it, so a capture taken before the paint committed could
have been measured as the cost of the canvas. The noise is now painted after the
screencast is running, through the same CDP session and behind two animation
frames, and only frames that arrive after that commit are used; none at all is
an error rather than a fallback. Re-measured across all 111 budgeted viewports:
0.543986 / 0.552964, unchanged to six decimals, so the constant stays where it
is and the capture is guaranteed rather than lucky.

* test(mobile): pin that a late dialog failure marks its own card, and quote the real case title (OTA phase C, C6.7 round 2)

Round 2 delta findings a and b.

The mis-stamp itself is already closed by the per-dialog token the bot fold
added: the failure updater skips unless the open card still carries the token of
the answer that armed it, and a dialog raised after that carries none. What was
missing is the sequence that proves it. The case answers the alert, lets the
page settle it and raise the confirm without the pane hearing the reply, then
times that reply out: the confirm keeps its own card and its live buttons. With
the token check reduced to the null guard it was reviewed with, the confirm is
stamped with the alert's failure.

The sweep docstring quoted a case title that does not exist, which is a pointer
that reads as a citation and resolves to nothing. It now quotes the real one.

* refactor(mobile): give the browser pane the one dialog-state type (OTA phase C, C6.7 bots)

pullfrog: the pane declared its own `BrowserDialogState` without `error` or

so the fields the card renders were undeclared on the pane's own state. The pane

Jinwoo Hong bd5177801b feat(mobile): put the page's pickers, paste and editor fallbacks on the media verbs (OTA phase C, C7.6) (#21795)
* feat(mobile): put media picking behind a platform seam (OTA phase C, C7.6)

The session screen picks images three ways — the photo library, Files, and the
pasteboard — and all three are native modules a page cannot import: the codegen
lookup `expo-image-picker` and `expo-document-picker` run at import throws in a
browser, and the route manifest imports every route, so one of them in a page
closure is the whole bundle down rather than one picker.

`src/platform/media-picker.ts` is the phone's, delegating to the same three
calls the screen already made. `.web.ts` is the page's: `native.media.pick`,
then `read` in order to `eof`, then `release` for every handle it was handed,
including the ones its caller never took — the shell holds eight staged files
at a time and an abandoned pick otherwise waits out the five-minute TTL. A
refusal rejects with the shell's code on it and is never folded into the empty
answer that means the user cancelled.

The bytes are concatenated decoded and encoded once, because the wire promises
`eof` and nothing about the length: a shell answering a range shorter than the
one asked for ends a chunk on a partial base64 group, and a reader joining the
strings would fold that padding into the middle of the file.

The census walks the session route module's own closure — the route is not
registered until C7.7 — and names any module that reaches a picker or
`Clipboard.getImageAsync` directly. Today that is the two modules C7.6's next
commit moves, listed by name so the list goes empty rather than the rule going
quiet.

Inert: nothing calls the seam yet.

* feat(mobile): put the session's paste and attach on the media seam (OTA phase C, C7.6)

The terminal paste read the pasteboard through `expo-clipboard` directly and
the two attach paths called `pickMobileImage`/`pickMobileImages`, so the page's
closure carried `expo-image-picker` and `expo-document-picker` — native modules
whose import throws in a browser.

All three now go through the seam. Text is `native.clipboard.read` on the page,
which the clipboard seam gains a reader for: `expo-clipboard` resolves to
`navigator.clipboard` there, which needs a secure context the iOS shell's
custom scheme is not. An image is `pick { source: 'clipboard' }` rather than an
inline value, because a clipboard image is 24 MiB of base64 against an 8 MiB
reply ceiling.

The census over the session closure is empty now and asserts the seam is in it,
so a rule that found nothing is one that had something to find: with the three
call sites restored it names all three.

`mobile-image-source-picker.ts` stays the phone's implementation, reached only
through the seam's native sibling, and resolves out of the web closure entirely.

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

* feat(mobile): resize a clipboard image on the page with a canvas (OTA phase C, C7.6)

The paste hook carried the raster shrink inline over `expo-image-manipulator`
and two `expo-file-system` writes. Both are native: the manipulator has no
browser build, and the temp file exists only to work around an iOS loader that
cannot decode a large base64 data URI, which a browser does not need.

Split into `mobile-clipboard-image-resize.ts`, unchanged, and a `.web.ts` that
decodes one `<img>` from the data URL the shell's `img-src 'self' data:`
already admits, draws it into a canvas at the target size and reads the PNG
back out of `toDataURL`. It reports the canvas's own size rather than the size
asked for, because a browser clamps a canvas past its area limit and the
downscale loop above would otherwise retry a raster that never shrank; and it
awaits `decode()` rather than `onload`, which never fires for a source the
browser cannot read and would leave the paste waiting on a promise nothing
settles.

Measured in Chromium under the shipped header, on a noise PNG because that is
what PNG compresses least: 1400x1000 encodes to 5,476,032 base64 characters and
converges in one pass to 368x263 and 397,220, which is 75.8% of the upload
path's 512 KiB chunk. Zero policy violations and zero page errors. Red under
three mutations: the source returned unchanged, a reported size the canvas did
not draw, and `onload` in place of `decode()`.

`computeMobileClipboardImageDownscale` moves to a leaf for the reason the
upload-chunk constant has one: the check wants the arithmetic and not the
upload path's RPC operations behind it.

The page closure now carries none of `expo-image-picker`,
`expo-document-picker`, `expo-image-manipulator` or `expo-file-system`, pinned
beside the seam census.

* feat(mobile): give the two WebView editors their plain web fallbacks (OTA phase C, C7.6)

`MobileRichMarkdownEditor` and `MobileHtmlPreview` are the session closure's
other two `react-native-webview` consumers. On the web that package renders the
line "React Native WebView does not support this platform" where the surface
was, so nothing it was mounted for works and the closure pays for a module that
cannot do its job.

Ruling 8: each gets the plain state it already degrades to, and no second
renderer. The editor renders the Markdown source in one field on the text-input
seam, so the screen around it keeps the text, every edit through `onChange`,
and Save, Discard, Copy and Refresh; the degradation is the formatting toolbar,
whose fifteen commands are the rich document's. The preview renders its own
Source tab; the degradation is the rendered artifact, and the toggle goes with
it, because a control that can only be in one position is a control that lies.

Neither is smaller than a DOM renderer, which is why neither is one here. The
editor's toolbar would need a `contenteditable` implementation with its own
escaping, and the preview has no nested frame to sandbox agent-produced HTML in
at all — the shell's policy carries `frame-src 'none'` and `child-src 'none'`.

`dismissKeyboard` blurs the field rather than calling `Keyboard.dismiss`, which
is a stub on React Native Web; `onKeyboardInsetChange` is never called, because
it exists to correct for a WebView's covered area and on the page
`keyboard-occlusion.web.ts` is the only measurement there is.

The closure census names the one consumer left, `TerminalWebView.tsx`, which is
C7.5's: with both siblings removed it names all three.

* fix(mobile): read a destructured clipboard alias in the media census (OTA phase C, C7.6)

The census recognised `Clipboard.getImageAsync` as a property access and
nothing else, so `const { getImageAsync } = Clipboard` reached the same
function without ever writing one and the closure was approved. On the page
that call is `navigator.clipboard`, which needs a secure context the iOS
shell's custom scheme is not, so the approval was for a path that dies at the
browser clipboard API.

Aliases are now resolved to a fixpoint — `const pasteboard = Clipboard` makes
`pasteboard` the module too, and the chain has no length limit — and a
destructuring off any of them is reported at its declaration, which is the line
to delete. The destructured name is read the way the import clause's is, off
`propertyName` when the element renames it, so `{ getImageAsync: readImage }`
is the same offence spelled differently. A binding element's `name` can be a
nested pattern and a `propertyName` can be computed, so the text is taken only
off a node that has one.

Red-first with each shape planted in the scratch tree before the rule moved:
the plain destructuring, the renamed one and the re-destructured chain were all
missed. Dropping the fixpoint afterwards loses the chain; reading the local
name instead of the property loses the rename. `{ getStringAsync } = Clipboard`
stays unreported, because text off the pasteboard is the clipboard seam's and
not this rule's.

The session closure is still empty under the widened rule.

* fix(mobile): release every item a clipboard pick answered (OTA phase C, C7.6)

`readClipboardImage` destructured the first staged item and released only that
one, while `pickImage` already guards the same shape through `readPicked`.
`multiple: false` is what the page asks for and not what a shell promises, so a
caller taking the first of several would hold the rest against the
eight-handle cap until the five-minute TTL. Today's shell stages at most one on
the clipboard arm, so this is the seam's own docstring made true rather than a
leak in the field.

Red-first with two staged clipboard items: releasing only the one read leaves
`media-2` held, and the second is now returned without ever being read, which
is what the single-image pick does.

The refusal case is one path over both codes a pick can answer with: the
registry's `native_media_handle_cap`, raised before a picker runs, and ruling
6c's `native_media_too_large`, raised once a picked item has been weighed. A
code outside the seam's vocabulary floors to `native_verb_failed` rather than
crossing verbatim, which is what makes naming the exact code load-bearing.

* test(mobile): read the upload chunk from its module in the resize check (OTA phase C, C7.6)

The canvas resize check restated `512 * 1024` as the budget it holds a run to.
A check carrying its own copy of a product constant is one that goes on passing
after the upload path's chunk has moved, which is the reason the harness reads
the CSP, the protocol version and the window caps out of their own sources.

`readClipboardImageUploadChunkBase64Chars` joins them, evaluating the product
the way the window caps reader does. Proved live by moving the constant: at
64 MiB the run reds on the fixture no longer being over the budget, and it is
back to 512 KiB here.

* fix(mobile): read element access in the media census and correct two claims (OTA phase C, C7.6)

Round 2, four lows.

The census read `Clipboard.getImageAsync` and not `Clipboard['getImageAsync']`,
which is the same call, the spelling a bundler produces, and the one a reader
reaches for to get around a rule about dots. Element access with a string
literal is now read the same way; a computed key is not, because its value is
not in the source and guessing would report a line nobody can act on. The
closure test cannot back this up — `expo-clipboard` legitimately sits in the
session closure — so the scratch fixture is the whole of the evidence, and it
reds with the arm removed.

The fixture also could not tell the alias fixpoint from one source-order pass:
every planted chain happened to be declared in the order a single walk learns
it. `reverse-order-alias.ts` is declared back to front, and is valid at run
time because the destructure sits inside a function the module body finishes
before anything calls. Bounding the loop to one pass now reds it.

The canvas resize justified reading its size back off the element by a browser
clamping past its area limit. That is not what browsers do: the width attribute
reflects whatever it was assigned, so the returned size is always the target.
The real reason is narrower and is now what the comment and the override entry
say — the dimensions and the bytes come from one element, so a caller's
bookkeeping cannot describe a raster that was not encoded.

The override entry also carried a stray apostrophe in `img-src 'self' data:`.

* fix(mobile): say what the clipboard contract shipped as, and read a backticked key (OTA phase C, C7.6)

Round 3, three lows.

The merge took main's `clipboard.ts` byte for byte, so its reader docstring
still described the state C7.2 shipped: one verb on the web, and a page whose
lack of an image verb degraded into the old path. The design that shipped is
the other one — this seam owns the pasteboard on both platforms and the page's
`readImage` runs `native.media.pick { source: 'clipboard' }` with the chunked
read behind it. The prose now says that, and says that null still means an
empty pasteboard while every other outcome rejects.

The same merge left `clipboard` twice in the paste hook's dependency list, one
from each side. Deduped.

The census read a quoted element-access key and not a backticked one, so
``Clipboard[`getImageAsync`]`` escaped a rule that catches both other
spellings. A template with no substitution is a string literal with a different
quote, and reading only one of the two leaves the other as the way around.

The computed-key plant could not see the literal-kind check at all: its
variable was named `key`, so reading the identifier's text found nothing
either way. It is now named after the method and holds a different one, which
makes dropping the kind check a false positive on a call that reads text.

Red-first: the backticked access planted before the rule moved is missed;
ignoring template keys afterwards misses it again; accepting any key node
reports the computed plant.

* fix(mobile): hold canPickMedia to all three verbs and seed the census from import() (OTA phase C, C7.6)

Two bot findings.

`canPickMedia` answered true on `native.media.pick` and `native.media.read`
alone, but every image read releases what it picked. On a route without
`native.media.release` the release rejects, the cleanup swallows it by design,
and the staged file stays live to the five-minute TTL: eight pastes and the
next pick is refused at the handle cap, with nothing on screen to say why. A
route missing one verb has no working image path, so `contents()` now says so
up front rather than after four of them. Red-first: a route granted pick and
read but not release answered `image: true`.

The census seeded its aliases from static import and export declarations only,
so `const Clipboard = await import('expo-clipboard')` produced no offender —
while the bundler resolves a literal dynamic import into the closure exactly as
a static one. A dynamic import is now read wherever it appears: `await` and
parentheses unwrapped, the assigned identifier seeded as an alias, a
destructuring off one reported at its declaration, and a picker module reported
at the call, since reaching one at all is the offence. A specifier that is not
a literal is left alone, for the reason a computed key is.

Red-first with all three forms planted and the seeding removed: the namespace
alias, the destructuring and the picker import are each missed.

* fix(mobile): seed the media census from a backticked import() too (OTA phase C, C7.6 bots)

CodeRabbit: `import(`expo-image-picker`)` is as static to the bundler as the
quoted form, but the census read only a string literal specifier, so a
backticked one joined the closure unseen. A no-substitution template literal
now seeds it the same way; the planted fixture is reported at its line and
was unreported before the arm.

pullfrog: the clipboard seam's docstring counted the web read as two verbs
where its web sibling counts one for text and three for an image. It now
counts the same way in both files.

Jinwoo Hong d5dc7b9cf8 feat(mobile): budget the terminal snapshot on serialized bytes and hold live output instead of ending the stream (OTA phase C, C7.3) (#21785)
* fix(mobile): budget the mobile terminal snapshot on the bytes it serializes to (OTA phase C, C7.3, ruling 1)

The desktop trims a mobile snapshot to 512 KiB of raw terminal text. A client
reading it through the page bridge measures the serialized event against a
640 KiB frame cap, and an ANSI snapshot is mostly ESC bytes, each of which JSON
spends six on. Measured here on a colour-dense 80-column screen: the raw budget
hands back 465,766 bytes that serialize to 669,268 — 102.1% of the cap — so
`deliver` answers `cancel(id, 'overflow')` and the terminal is dead before its
first live byte, with no recovery that does not reproduce it.

`terminal.subscribe` gains an optional `snapshotByteBudget`. A subscriber that
sends one is trimmed against the JSON its payload will really cost: the escaped
text, plus the metadata it cannot bound from its own side — a path, the OSC-link
list, the pending escape tail. A subscriber that sends none, which is every
socket client and every older page, keeps the raw byte rule exactly.

No negotiation, and none is needed: the field is additive and optional, so an
older desktop ignores it and trims as it always did. The page then still has a
snapshot over its cap, the shell still ends the stream with `overflow` (C0.3
stands), and the terminal renders its stream-error state rather than a blank
pane. The page derives the number from the cap less the event envelope rather
than writing it down, so a cap that moves takes the budget with it.

* feat(mobile): hold and coalesce terminal output instead of ending the stream on the window (OTA phase C, C7.3, ruling 2)

The shell's backpressure window ends a stream when the page falls 4 MiB behind.
That is right for a stream whose reader can survive a gap and wrong for a
terminal, whose reader cannot see the hole a dropped chunk leaves — and the
window does not wait for a page to go wrong. Measured by the design: the host
produces 70.3 MiB/s of JSON and real xterm applies 2.2 MiB/s, so an ordinary
`cat` crosses the window in 62 ms. Replayed here through the real ledger against
a page draining at that rate, a 5 MB transcript ends the stream after 85 of 107
chunks plain and after 40 of 107 under `grep --color`.

Keyed by method on the shell, since the page cannot pick its own window,
`terminal.subscribe` now holds what it cannot send, merges consecutive output in
escaped bytes under the frame cap, and delivers as the page acks. Nothing is
dropped: merging concatenates, and the only exit that loses bytes is ending the
stream, which the page is told about. Both transcripts now arrive whole and in
order, in 104 and 81 frames, with the largest frame at 622,551 bytes against the
655,360-byte cap.

It ends only on the two things that are not slowness: a page that has acked
nothing for 20 s, an order of magnitude above the 1.9 s a full window takes to
drain, and a backlog past 32 MiB, which at that drain is about 15 s of catching
up. Both reach the page as `overflow`, because the shell is the installed app
and its page comes from the desktop, so a reason the page's reader has never
heard of is a frame it drops rather than an end it acts on. Which one fired, the
coalesced-frame count and the peak pending bytes go to the diagnostic log, which
is the device proof's only oracle for any of this.

Every other stream keeps the byte window exactly, and an event over the frame cap
still ends any stream, terminal or not (C0.3). The landed window cases now name a
stream the window still governs, so the two rules are never read off each other.

* refactor(mobile): narrow the snapshot serializer to the buffer source it reads

The changed-code casting gate refused the test's stub runtime, and it was right
to: a service-wide type for a function that calls one method is what made the
stub need an assertion. The parameter now says what it needs, and the fixture
path is no longer one a machine-path grep reads as a leaked local checkout.

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

* fix(mobile): measure the snapshot budget by building the payload, not by summing fields (OTA phase C, C7.3, ruling 14)

Round one summed the escaped text and four metadata fields. The payload a
bridged client assembles carries nine more — `kind`, `cols`, `rows`,
`requestId`, `displayMode`, `reason`, `seq` and both truncation flags — plus the
`type` and `streamId` it adds, the `serialized` key and the object's own braces.
So a snapshot this host accepted at exactly the budget, with
`truncatedByByteBudget` false because nothing had trimmed it, published over the
cap and the stream ended with `overflow` before a byte was painted.

Measured here on a screen sized to land exactly on round one's budget: the
published payload is 655,446 bytes against a 655,273-byte budget, 173 over, and
the frame it makes is over the 640 KiB cap by the same amount.

The metadata is now built by one function that `sendSnapshotFrames` and the
budget both call, and the budget stringifies the payload that function produces.
Nothing is summed and nothing is estimated, so a field added to the frame is paid
for by the budget the moment it is sent. Where a value is not yet known — the
truncation flags, and `seq` or `requestId` at a site that has not fixed them —
it is measured at the widest `JSON.stringify` can write it, which is a bound
rather than a guess, and forcing `seq` to a number also opens the three fields it
gates so those are counted too.

The budget therefore travels with the publication fields, because the payload
cannot be built without them.

On the page, the event envelope is now derived in one place in the protocol
module and read by both the snapshot budget and the shell's own merge budget, so
the two cannot drift; the page pins the number it sends and the host's cases name
that pin, since the two programs cannot import from each other.

The case that re-implemented the host's measure is gone: it could not have seen
this, because it was the same arithmetic twice.

* fix(mobile): arm a held terminal's silence clock only while something is pending (OTA phase C, C7.3)

The invariant is "armed implies waiting on the page", and round one broke it in
the one direction that kills: an ack re-armed the clock and the drain that
followed emptied the queue without clearing it. A terminal that had delivered
every byte and gone quiet — which is what a terminal does between commands —
would die on `overflow` twenty seconds later.

The clock is now synchronised after every change to the queue, so it is armed
exactly while something is held. A rule that only ever arms is a rule that only
ever ends more streams.

Red-first: with round one's arming, an idle stream whose queue has drained still
reports its clock armed, and firing it ends a healthy terminal.

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

* test(mobile): pin the held-stream cases the rulings name (OTA phase C, C7.3)

Six cases nothing covered. Two subscriptions on one shell keep separate backlogs,
so a busy terminal cannot end a quiet one. A stream the page unsubscribed mid-
backlog posts nothing after, and neither does one that has already ended, however
much was still held. A payload that is not output breaks a merge run and keeps
its place, because a resize is state the reader applies in order. And the budget
boundary is checked on the side that enforces it: a payload at exactly the number
the page asks the desktop for is delivered inside the cap, and one the cap cannot
hold ends the stream under C0.3.

The replay no longer acks unconditionally in its catch-up loop. That was the page
behaving better than a page can — it acks on reading frames — and it is what hid
the silence clock left armed over an empty queue. The held-stream cases close the
window on its frame count rather than on four megabytes of string work.

* refactor(mobile): give the event-envelope derivation its own module (OTA phase C, C7.3)

`bridge-envelope.ts` is at its line cap and is the protocol's schemas; what a

it — the snapshot the page asks the desktop for, and the output the shell merges.
One module, so they cannot drift and neither file is pushed over its limit.

`terminal-snapshot-publication.ts` crossed the root config's 300-line cap, which
mobile's own lint does not apply and CI does. The frame's shape and what it costs
a client reading it as one payload is a description the budget and the sender
both need, so it is the part that leaves.

* fix: empty a snapshot the budget cannot fit instead of posting it over (OTA phase C, C7.3, ruling 15)

Both trimming loops published the zero-row candidate whatever it measured, and
zero scrollback is not a small screen: a wide colour-dense viewport still carries
its 24 live rows. A capped subscriber could get one frame over its cap, end the
stream on `overflow` and paint nothing — worse than a blank terminal, because a
blank one repaints on the next byte of output and a stream that never opened does
not reopen.

Ruling 15: a budgeted subscriber gets that frame with its text emptied and
`truncatedByByteBudget` true, never over and never refused. The raw rule keeps its
fallback, so an older page and every socket client are served exactly what they
were before. Below the metadata the frame must carry there is nothing left to give
up, and that boundary is pinned rather than claimed away.

The renderer loop is the same walk reached by a different caller and had no test
at all; its runtime parameter is narrowed to the two methods it reads so a case
can stub it without a cast.

* fix(mobile): report what a held terminal stream did instead of calling it an outlived view

The backlog report had no branch in the reporter, so it fell through to the "a
view outlived its host" warn and every field it exists to carry was discarded.
The key made it worse: keyed by kind alone, one backlog per host was ever logged,
and a shell holds one stream per open terminal.

That report is the only oracle the coalescing rule has. Nothing crosses to the
page saying how much was held or how many frames its bytes arrived inside, and
both ways a held stream dies reach the page as `overflow`, because a reason its
reader has never heard of is a frame it drops. In production the two rules were
indistinguishable. They are now a line each, per stream.

* test: give the renderer fixture the source its serializer returns

`serializeRendererTerminalBuffer` answers `renderer`, and vitest does not

typecheck instead.

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

* fix: budget the frame the publication actually sends (OTA phase C, C7.3)

The budget and the publication were written out twice, five lines apart, and had
drifted at every site: a budget for `{kind:'scrollback'}` approved a frame sent as
`kind:'resized'` with a `reason` beside it, and the live module budgeted
`pending-output-overflow` while sending `renderer-mount-ready`. It held only
because the padded `requestId` and `seq` are absent from those frames and more
than covered the difference. Each site now builds one object and hands it to
both.

`displayMode` cannot travel that way and was a third under-measure nobody had
named: the subscribe flow re-reads it from the runtime after the snapshot is
serialized and before the frame is sent, so no caller can tell the budget which
mode the publication will carry. It joins `seq`, `requestId` and the truncation
flags as a field taken at its widest. The mode list resolves the constant to
`never` if the runtime gains a mode it does not carry, so a new one is weighed
here rather than found on a phone.

Red-first needed a second attempt: the first fixture had trimming slack, so three
extra bytes fit and the probe could not see the defect it was written for. The
case now budgets a fixed screen at exactly its `auto` measure, where the margin
is the whole of the test.

One figure for the overshoot everywhere, with its basis: 169 bytes over the
655,360-byte cap on a frame carrying an 8-character request id, 247 with a
24-character one. Three places said 169 and one said 173.

* refactor(mobile): delete two backlog guards no input can reach

Both survived mutation because neither is reachable, and neither became
reachable when I tried to write a case for it.

`next` narrowed the merge ceiling to one frame, but its only caller,
`drainTerminalBacklog`, has already narrowed it: the parameter is what one
payload may occupy, not what the window holds, so the second narrowing could
never change the answer. The parameter now says so and the class no longer needs
the frame size at all. The bound still lives in the caller and is still covered:
removing it there reds a delivery case.

The merge run also compared stream ids, but a backlog belongs to one subscription
and every `data` payload on it carries that subscription's single stream id, so
the comparison could not fail. The run still stops at anything that is not
output, which is reachable and pinned.

* docs(mobile): record the invariant the deleted stream-id guard rested on

The merge run compares no stream ids because it cannot need to: a backlog belongs
to one subscription and every `data` payload reaching it carries that
subscription's single stream id. Written down where the run is, because the thing
that would break it is a change made somewhere else — multiplexing two streams
onto one record would merge their output into one payload under the first id.

* feat(mobile): put the session screen's nine text inputs on the web font seam (OTA phase C, C7.2)

The landed text-input census, run over `app/h/[hostId]/session/[worktreeId].tsx`,
reports nine sizes that do not come from `TEXT_INPUT_FONT_SIZE`. Six declare the
app's body size and move in place, which is the same number natively. Three do
not — a 22px key-capture field and the chat's two 15px fields — so each gets a
`.web.ts` sibling of the address bar's shape, with a shared base so the two
halves can differ in nothing but the size.

The capture field is the one the move shrinks rather than raises: 22 already
clears the focus-zoom floor, and the census reads the seam as a binding rather
than as a number, so there is no expression that keeps 22 and still says where
the size came from.

* feat(mobile): open the session screen's three external URLs through the platform seam (OTA phase C, C7.2)

The landed external-link census, run over the session route's closure, reports
three modules reaching react-native's `Linking`: a terminal link tap whose open
mode is the phone's browser, and the two WebView-backed readers, each of which
sends a tapped link to the system browser rather than navigating the artifact
away.

Inside the shell `Linking.openURL` calls `window.open`, which both shells refuse
and which resolves either way, so all three reported success into a tap that did
nothing. The seam also stops swallowing the failure: each site caught and
discarded, and `openExternalLink` names it.

* feat(mobile): take the session screen's seven clipboard sites through the platform seam (OTA phase C, C7.2)

`expo-clipboard` resolves to `navigator.clipboard` on the web, which needs a
secure context — iOS serves the page from a custom scheme and Android from
`https`, so that path works on one platform and silently not on the other. The
landed census now reports the module out of the route's closure entirely.

The seam grows its reader half, on the landed `native.clipboard.read` verb: text,
a PNG, and a presence probe. Two degradations are recorded rather than implied.
No shell serves an image, so the page answers null and the terminal's paste takes
the branch an empty clipboard already took; and the shell serves no presence verb,
so `contents` answers what this side knows rather than reading to find out, which
would raise iOS's paste-consent prompt on every foreground.

The copy-path sheet gains the failure toast its two neighbours already had: it
showed "Path copied" before the write, and the seam rejects rather than returning
false.

The route parity pin moves with it: five clipboard hooks join the expanded route
and one runtime string joins the sheet.

* feat(mobile): take the session domain's three routers through the handoff seam (OTA phase C, C7.2)

Inside the page a screen is one document standing in for one screen, and
`useRouteHandoff` is the only thing that knows which targets the page keeps and
which it hands back to the app. The three holders here are the workspace-missing
bounce, the file-tap preview push, and the pane-tap param consume.

The domain's census is narrower than the two landed ones because it has to be:
eight of its hooks take `useFocusEffect` and two take `useLocalSearchParams`,
neither of which can navigate, so the rule is a closed list of names rather than
a ban on any value import — which also catches expo-router's module-singleton
`router`, a spelling a `useRouter` rule would have read as clean.

* feat(mobile): list the two style siblings the session screen's inputs added (OTA phase C, C7.2)

The overrides census fails on an unlisted `.web.*`. One raises the chat's two

the seam, and its entry says why a reduction is the right answer there.

* feat(mobile): let the text-input census read a literal already clear of the floor (OTA phase C, C7.2, ruling 12)

The floor is the rule and the seam is the mechanism. A binding rule alone made
the custom-key capture field an offender at 22, where nothing can zoom, and the
only way to satisfy it was to lower a one-character field to 16 — the tail
wagging the dog.

The seam's web half now exports the floor it already computed `Math.max` against,
and the census reads that number out of that file rather than carrying a second
copy of 16. The rule becomes "the seam's binding, or a literal at or above the
floor", with no per-site exemption: a literal under the floor is still reported,
which is the case the seam exists for. A tree whose seam declares no floor is
refused rather than judged against a number the census invented.

So the capture field goes back to 22 on both platforms and its split, its
override entry and its parity test go with it. The chat's two fields stay split,
because 15 is under the floor however it is spelled.

Red-first: with the rule removed, a planted literal 16 and a literal 22 are both
reported and the refusal case does not throw; a literal 15 is reported either
way. All three route closures that run this census — session, source-control,
review — report 0 offenders and 0 unresolved.

* fix(mobile): answer clipboard reads on the read grant and catch refused writes

`contents()` reported no text on a route that granted `native.clipboard.read`
without the write, because it read `verbs.granted`, which is write AND read. The
verbs hook now exposes the two grants separately and the web seam answers on the
read one; `granted` keeps its meaning for the callers that need both.

The Markdown copy action was the one write of eight in the session domain with
nowhere for a rejection to go: the seam rejects when the pasteboard refused the
text, the callback had no failure branch, and its caller drops the promise, so a
refused write raised an unhandled rejection and still left "Copied" on screen. It
now takes the error haptic and the "Couldn't copy" toast the other copy paths
show. A census over `src/session` fails if any `writeText` call site lacks a
failure branch, so the ninth site cannot arrive without one.

The route parity pin moves with it: one callback body, one runtime string. Its
refresh note claimed six clipboard hook sites for a delta of five; the walk from
`SessionScreen` reaches five, and the terminal's paste is not among them.

* fix(mobile): probe both clipboard kinds at once and judge sizes against the floor

Moving the two clipboard probes into an object literal serialised them: the

where both callers had used `Promise.all`. That path runs on mount, on every
AppState foreground and on every select-mode toggle. Restored, with an ordering
probe that deadlocks unless both probes start before either answers.

The floor case could not fail for the reason it named: its fixture declared 16,
so a census carrying its own copy of 16 passed it. It now plants a seam declaring
20 and a literal 18, the size that is clean under one floor and an offence under
the other.

Two stale wordings from the reverted split: one closure case still said "both

* fix(mobile): buzz the quick-command row when a copy is refused

The last of the seven migrated writes without the error haptic. The row already
said "Couldn't copy" on its own control, in red, for the 1500 ms the toast the
other six show would have lasted, so it never claimed a refused write had landed;
what it had no way to say was anything the thumb still on the button could feel.

Its first test, on the harness its list already uses: the seam rejects when the
pasteboard refuses, and the two cases are the difference between the row that
shows a green check over nothing copied and the row that does not. The list's own
test gains the haptics mock the row's new import needs.

* fix(mobile): make the clipboard census require the await its rule depends on

`hasFailureBranch` accepted any enclosing `try` with a `catch`, so the one shape
the census exists to stop passed it: `void clipboard.writeText(...)` inside a
try/catch is an unhandled rejection with a handler three lines above it that can
never run, because the block returns before the promise settles. It now requires
the call to be awaited inside the try's own block, or to carry a `.catch` along
its own chain. The boundary walk stopped only at function and method
declarations, so a `catch` outside an arrow answered for the call left running
inside it; every function-like node ends the search now.

Five cases over snippets read through the same reader, because a `void` write
would have to be committed to be tested against the real tree. Control on a real
site: making the Markdown write un-awaited inside its own try reports it.

Two provenance fixes. The runtime-string delta across C7.2 is two literals, not
one: "Couldn't copy path" took the count from 532 to 533 and "Couldn't copy" took
it to 534. And main's C7.4 made `BRIDGE_CLIPBOARD_MIMES` `['text']`, so an image
mime is a value the schema does not admit rather than a refusal the verb spells
out, with `native.media.pick { source: 'clipboard' }` waiting on C7.6; the web
seam and its test said otherwise. Behaviour unchanged.

* fix(mobile): let an unmounted quick-command row emit nothing on a refusal

The haptic I added ran before the mounted guard, so a copy pressed on a row that
then scrolled out of the list, or a sheet closed over it, still buzzed when the
rejection arrived. A buzz with no row to explain it is feedback for nothing, and
the guard was already there for the feedback state one line below.

Red-first: press, unmount, then reject. The success path already guarded first.

* fix(mobile): make the clipboard census require a catch with something in it

Any `.catch` property access counted as a failure branch, so two shapes that
handle nothing passed: `clipboard.writeText(text).catch` reads the handler's name
and registers nothing, and `.catch()` swallows the rejection while the caller goes
on to say the write landed. The rule now requires `.catch` to be the callee of a
call carrying at least one argument.

Red-first with both shapes in the snippet reader, the accepting cases unchanged.
Control on the real tree: emptying the notes sheet's handler reports
`MobileSessionSheets.tsx:174`, and restoring it greens.

Jinwoo Hong e5181113ca feat(mobile): add the media verbs the page's pickers and paste will use (OTA phase C, C7.4) (#21779)
* feat(mobile): add the media verb rows to the shell's native table (OTA phase C, C7.4)

`native.media.pick`, `native.media.readChunk` and `native.media.release` join
`BRIDGE_NATIVE_VERB_NAMES`, so each becomes a grant name `init.grants.native` can
carry and each gets a strict zod contract in `bridge-media-verbs.ts`. A chunk read
is held to the upload path's own budget, imported rather than restated: the leaf
module `mobile-clipboard-image-upload-chunk.ts` now declares
`MOBILE_CLIPBOARD_IMAGE_UPLOAD_CHUNK_BASE64_CHARS` so the bridge can read it
without pulling the upload path's RPC operations into every page closure.

Inert: no page calls the verbs and no route declares them, so an older page never
names them and an older shell refuses them as `unknown-verb`.

`native.clipboard.read`'s `{ mime: 'image' }` refusal is retired rather than left
pointing at nothing. The broad shape existed so a later build could serve an image
without a contract change; that build is `pick { source: 'clipboard' }`, which
stages the image behind a handle instead of inlining 24 MiB of base64 through an
8 MiB reply. The mime enum is text only, the handler's out-of-scope arm is gone,
and the refusal's test flips to the new answer: `invalid-params`, before dispatch.

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

* feat(mobile): give the shell the staged-media handle registry (OTA phase C, C7.4)

A handle names a file this shell copied into its own cache, and such a file has no
owner otherwise: the page that asked for it is a document that can navigate, fault
or be swiped away without telling anyone. So the lifetime is bounded four ways and
all four are here — the page's own `release`, `MEDIA_HANDLE_TTL_MS`, and
`releaseAll`, which both the session's end and the page's unmount reach through
`useMediaHandleRegistry`. The TTL is measured from the last touch, not the mint, so
a page reading a large file one chunk at a time cannot have it swept out from under
it; its five minutes is sized for the page that picked and then stopped, not for
the read, which is 48 round trips on the largest item a pick may stage.

`BRIDGE_MEDIA_MAX_LIVE_HANDLES` caps what one session holds. A pick that would pass
it is refused whole and discards what it staged: half a multi-select is an answer a
page cannot tell from a user who picked fewer.

Three refusals join the seam's vocabulary. `native_media_handle_unknown` covers
never-minted, released and swept alike — which of the three it was is a fact about
another page's pick. `native_media_range` refuses a read at or past the end of an
item that had bytes, because the previous chunk already said `eof` and an empty
answer would let a page loop instead of failing where the bug is.
`native_media_handle_cap` is the cap above.

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

* feat(mobile): serve the media verbs on the device, behind staged handles (OTA phase C, C7.4)

`pick` runs the OS permission prompt inside the shell — `expo-image-picker` for the
library, `expo-document-picker` for Files, the pasteboard for `clipboard` — stages
each item as a file this shell owns, and answers handles. `readChunk` reads the
byte range the registry hands it and base64-encodes it through the upload path's
own accumulator; `release` deletes the file.

The device calls live in `native-media-device.ts` and nothing else. Importing
`expo-image-picker` imports React Native, so a module naming it cannot be driven in
a unit test at all, and the arms worth pinning are exactly the ones a simulator
makes expensive: a denied permission, a cancel, an item over the staging ceiling.
`native-media.ts` takes those seven calls as dependencies and is tested whole.

Two refusals join the vocabulary, each because a page acts differently on it.
`native_media_permission_denied` is a permission the user can still grant in
Settings, not a library the shell could not read. `native_media_too_large` is an
item over `MEDIA_STAGED_MAX_BYTES`, weighed from the staged file rather than from
what the picker declared, since a picker's own size is optional on both platforms.
A pick refused that way discards every file it staged.

Each chunk is base64 on its own, so a page concatenates decoded bytes and never
strings: only the last chunk of a read ends on a partial group.

Measured: the largest reply this verb can produce is a full
`MOBILE_CLIPBOARD_IMAGE_UPLOAD_CHUNK_BASE64_CHARS` chunk, 524,427 bytes on the
wire with its envelope — one frame, 80.0% of the 640 KiB frame cap and 6.3% of the
8 MiB reply ceiling. Pinned in `native-media.test.ts`, so a cap or an envelope
field that moves shows up as a diff.

* fix(mobile): only mint a media handle over a file this shell owns (OTA phase C, C7.4)

The Android arm of the same handler. Both pickers are configured to hand back a
copy in this app's own cache — `expo-image-picker` always copies, and
`expo-document-picker` does under `copyToCacheDirectory` — and the whole handle
contract rests on it: `release` is a delete, and so is the TTL sweep. A provider
that answered `content://media/...` instead would mint a handle over a file this
shell can neither size nor delete, and every sweep would be a silent no-op that
leaves the cache growing. `ownsStagedMediaUri` refuses that where the assumption
is made rather than letting it surface as a cache that never empties.

`native-media-device.test.ts` pins the options that make the assumption true: the
document picker's `copyToCacheDirectory`, the library picker's `base64: false` and
its selection limit, the pasteboard's png, and the cache file `stageBase64` writes.

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

* test(mobile): move a picked image across the real pair, chunk by chunk (OTA phase C, C7.4)

Through `createFakeBridgePortPair` rather than the host alone, because a chunk is
the one reply this seam produces that is within a rounding error of the frame cap:
a case that called the server directly would never serialize one, and serializing
is where a reply that fits and a reply that splits part ways.

A granted page picks an 18 MiB item, reads all 48 chunks in order to `eof` and
releases it; the decoded length is the file's own and both ends are the fixture's,
which a reader that dropped or reordered a chunk would not have. Nothing reaches
the desktop client. A page granted only `navigate` and `storage` is refused
`native_verb_ungranted` with no picker run — the refusal is the host's, because
the page side of these verbs is C7.6's. A released handle, a swept handle, a read
past the end and a pick over the live-handle cap each come back under their own
code.

The pair's default verb handler answered a clipboard shape for every verb, so a
media call through an unconfigured pair came back as `native_verb_result` — a
shell bug's code for a harness that was never told about the verb. It now answers
one shape per row of the table.

* test(mobile): drop the four type assertions the changed-code gate found (OTA phase C, C7.4)

`new Array<T>()` for the two hoisted mock ledgers, and the probe holds its handler
in a record it null-checks rather than asserting one that a render might not have
produced.

* fix(mobile): rename the chunk verb to native.media.read, which a manifest may name (OTA phase C, C7.4)

`native.media.readChunk` is not a legal grant name. `GRANT_NAME_PATTERN` holds every
`native.` segment to `[a-z][a-z0-9]*`, so a route declaring it fails
`MobileWebBundleRouteSchema` — and `bundled-mobile-web-bundle.ts` parses the manifest
whole, so the camel-cased segment is not a route that degrades to its native screen.
It is a bundle the phone rejects entire. Params are unchanged.

The test that would have caught it now reads the schema itself rather than a copy of
its pattern: every entry of `MOBILE_WEB_SHELL_GRANTS`, and every name in
`BRIDGE_NATIVE_VERB_NAMES`, parsed as the grants of a manifest route. Both lists,
because the spread is what makes them agree today and a build that stopped spreading
would leave this the only thing that noticed. Red on the old name with the exact
message: `native.media.readChunk: expected false to be true`.

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

* test(mobile): exercise a short read, which nothing separated from the chunk cap (OTA phase C, C7.4)

Every other read in the suite asks for a whole chunk of a file shorter than one, so
a handler that ignored `length` and read to the end passed all of them: the fake
file clamps at its own size. Replacing the range with the cap left 74/74 green.

A 16-byte read at offset 400 of a 1000-byte item now pins the length, the offset and
`eof: false`. Under that same mutation it reds with `expected 600 to be 16`, and it
is the only case that does.

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

* test(mobile): kill the four device arms that survived mutation (OTA phase C, C7.4)

Each was green with the arm removed; each now reds with it removed and nothing else
does.

The data-url strip: `getImageAsync` answers `data:image/png;base64,...`, which is
what an `<Image>` source wants and not what a file wants. Staged unstripped, every
byte is shifted by the prefix and the page decodes a corrupt image with no error
anywhere. The old fixture had no prefix at all.

The cancel flag: both pickers answer `assets: null` beside `canceled: true` today,
so a handler keyed on the list alone passed every fixture here. The new case sends
the flag with a populated list, which is what a picker version that changed its mind
would send.

The unknown mime: an empty string is not a mime the result schema takes, so the
alternative to the floor is `native_verb_result` — a shell bug's code for a document
picker doing what it may do.

The handle close: a ledger per opened handle, asserted on the way out and on the way
through a reader that throws. A file handle a shell leaks is invisible on a fake and
a file descriptor on a phone.

* test(mobile): pin the stated constants as literals (OTA phase C, C7.4)

The TTL, the live-handle cap, the handle and mime lengths, and the 48 chunks an
18 MiB item reads in. Literals, not the constants restated: every one is a number a
body claims and a reviewer checked, and read through its own name the assertion
would hold whatever it became — which is what the 524,427-byte reply pin already
does for the frame it measures.

Each reds when its number moves: 8 to 12, 64 to 32, 128 to 256, five minutes to ten.

* test(mobile): name the fixture by its size, assert the clipboard refusal, reach the clamp (OTA phase C, C7.4)

Three minors from round 1.

The case that said "18 MiB" staged a million bytes. Renamed to what it stages, with
a line saying the largest item a pick may hold runs in the port-pair suite, where
the frames are serialized and the size is the one that matters.

The clipboard image case had been weakened to a bare `.rejects.toThrow()`, which
would pass for a handler that reached the pasteboard and failed there — the one
outcome it exists to rule out. It now asserts a `ZodError` naming the `mime` path,
and reds when the parse is taken out.

The registry's chunk clamp was unreachable behind the params schema. Kept and
reached rather than deleted: the two bounds are different promises, one saying what
a page may ask for and one saying what the registry will hand any reader, and
`read` is a public method its own suite already calls directly. A case asks for
three chunks at once and gets one; it reds when the clamp goes.

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

* fix(mobile): copy a provider uri into the cache instead of refusing the pick (OTA phase C, C7.4)

`MediaHandler.readExtras` in expo-image-picker 55.0.24 has a reachable arm: when
`toMediaType` cannot resolve a MIME it answers
`ImagePickerAsset(type = null, uri = uri.toString())`, the provider's own
`content://` uri, uncopied. The OS completed that pick, so refusing it as
`native_verb_failed` loses a photo the user chose — and the comment above the guard
claimed both pickers "always" answer `file:`, which the same file disproves.

The pick now copies what it does not own into the shell's cache and mints the handle
over the copy, which is what the body already claimed. The guard stays for anything
the copy could not adopt, and that arm still fails closed: a sweep that can never
delete anything must not look like one that did. The failure path discards what this
shell owns rather than the uris the picker answered, since a provider's uri was
never ours to unlink.

Copied through `bytes()` rather than `copy()`: `FileSystemPath.copy` goes to
`javaFile.copyRecursively`, a `java.io.File` with nothing to open for a provider uri,
while the read path goes through the unified file and does. A source that cannot be
read takes the empty destination with it, because the caller never learns that name.

Red-first: a fixture answering `content://media/external/images/media/42` asserting a
handle over a `file:` copy, its 300 bytes read back whole, and the copy being what
`release` deletes.

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

* fix(mobile): bound a multi-select to the room the registry has left (OTA phase C, C7.4)

`selectionLimit: 0` means unlimited to the OS picker, and `mint` then refuses the
whole pick past `BRIDGE_MEDIA_MAX_LIVE_HANDLES`. A user who chose nine photos waited
through the OS copying every one of them into the cache to be told none were taken.

`pick` now reads `remainingCapacity()` before it launches anything: an empty room is
`native_media_handle_cap` up front, for every source, with no picker run and no byte
copied. What room is left becomes the picker's `selectionLimit`, so the selection
cannot exceed what the registry will accept and the refusal after the fact is only
reachable by a page that never released what it holds.

`getDocumentAsync` takes no selection limit, so for Files the room is the up-front
refusal only; `mint` remains the bound that cannot be skipped.

Each pin reds on its own mutation: dropping the up-front refusal, putting
`selectionLimit` back to 0, and fixing the limit at the cap instead of the room.

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

* fix(mobile): ask for the library permission on iOS only (OTA phase C, C7.4)

Read from expo-image-picker 55.0.24, not from the docs. Neither platform's
`launchImageLibraryAsync` gates on a permission: `launchCameraAsync` calls
`ensureCameraPermissionsAreGranted` on Android and `hasGrantedPermission` on iOS, and
the library arm goes straight to its contract on both. On Android
`getMediaLibraryPermissions` answers an empty array from API 33, so the request
prompts nothing and always resolves granted; below 33 it asks for
`READ_EXTERNAL_STORAGE` and `WRITE_EXTERNAL_STORAGE`, which the system picker never
reads, and a denial there reached `native_media_permission_denied` for a pick the OS
would have completed. Android no longer asks.

iOS still does, because the prompt inside `pick` is what ruling 6 asked the shell to
own and the photo-library dialog is a real thing a user sees there.

One finding for the lead rather than a silent change: with `allowsEditing: false`
the iOS path is `launchMultiSelectPicker`, a `PHPickerViewController`, which also
opens without authorization. So the iOS request is the ruling's and not the SDK's,
and a denial refuses a pick that would have worked. Dropping it is a ruling-6
amendment, not mine to make.

Both arms pinned and both red under their mutations: asking everywhere fails three
cases, asking nowhere fails two.

* test(mobile): mock react-native in the device-verb hook suite (OTA phase C, C7.4)

The hook reaches `native-media-device.ts`, which now imports `Platform`, and reaching
the real module imports React Native — which this suite has no runtime for, so it
failed to load and ran zero tests while the run still reported every other file
passing. The device half's own platform arms are `native-media-device.test.ts`; here
the OS only has to be one.

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

* fix(mobile): ask for no library permission on either platform (OTA phase C, C7.4)

Ruling 6b. `launchImageLibraryAsync` gates on nothing in expo-image-picker 55.0.24:
Android goes straight to its contract and iOS to `launchImagePicker(.photoLibrary)`,
and only the camera arm checks a permission. The prompt "inside the shell" that
ruling 6 asked for is the OS picker's own, so `pick { source: 'library' }` adds
none. `requestLibraryPermission` is gone from the deps, from the device calls and
from `pickFrom`, and with it the last way a denial could refuse a pick the OS would
have completed — Android below API 33 for storage permissions the picker never
reads, iOS for a `PHPickerViewController` that opens without authorization.

`native_media_permission_denied` stays in the refusal vocabulary, documented for the
first source that needs one rather than for a producer this build has.

Red-first, and driven through the whole verb rather than through `launchLibrary`
alone, since the request was `pick`'s and a case that only called the picker would
have passed either way: with the request restored, the pick on iOS calls the
permission API once and the deps still carry the member, and both cases red.

* fix(mobile): sweep before release, and name one basis per ratio (OTA phase C, C7.4)

Two lows from round 2.

`release` was the only lifetime path that did not sweep first, so an expired handle
was still in the map when it looked and the page was told `released: true` for a file
the next sweep would have taken anyway — the opposite of what
`mediaReleaseParamsSchema`'s docstring promises it. It sweeps now, like every other
path that reads the map. Red-first with the reviewer's own probe: expired, then
released, answered true. The exact boundary is pinned while we are here, because the
sweep's comparison is inclusive and nothing said so: at exactly `MEDIA_HANDLE_TTL_MS`
the handle is gone, one millisecond earlier it is not.

The raw ceiling was called "three times the reply ceiling" in two places.
`CLIPBOARD_IMAGE_MAX_SOURCE_BYTES` is 18,874,368 against 8,388,608, which is 2.25;
three is the ratio after base64 expands it. Both sentences now name which basis they
are on, and say that the two differ.

Each pin reds on its own mutation: dropping the sweep from `release`, and loosening
the sweep's comparison to exclusive.

* fix(mobile): never sweep a uri this shell does not own, and weigh before copying (OTA phase C, C7.4)

Round 3's five items.

(1) `owned.push(uri)` ran before the ownership guard, so a copy that could not be
adopted sent the provider's own `content://` uri to the failure path's discard — the
one thing the array's docstring says it never holds. The push now happens below the
throw, inside a named `adopt` that either hands back a uri this shell owns or throws
having claimed nothing. Red-first: the refusal case discarded exactly
`["content://media/external/images/media/42"]`.

(2) The copy's docstring claimed the in-memory read was bounded by a ceiling checked
"right after", which ran after the whole `bytesSync()`. The source is now weighed
before the copy, which is real: `FileSystemFile.size` routes a `content:` uri to
`SAFDocumentFile.length()`. A provider reporting nothing answers 0 there, so the
docstring also says what is true for that case — the read is bounded only by
`mediaTypes: ['images']`, and the copy is weighed after the fact instead. The copy's
own size stays authoritative for the handle.

(3) Both `react-native` mocks went inert when `324c4093be` dropped `Platform`. Gone,
along with the two-platform loop that had become one code path run twice; the 6b
guard now reads "never calls `requestMediaLibraryPermissionsAsync`", which is what it
was checking.

(4) The hook case no longer claims a permission prompt.

(5) The 150-character comment is wrapped, along with the three other comments over
100 that I had authored in this file and the two platform modules.

Each behavioural pin reds on its own mutation: pushing to `owned` above the throw,
and dropping the pre-copy ceiling check.

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

* fix(mobile): refuse what cannot be weighed, and count a Files pick before staging it (OTA phase C, C7.4)

(a) The pre-copy weigh is now a mechanism rather than a docstring, and the branch it
takes is the one the SDK allows. Verified in expo-file-system 55.0.26: a `content:`
uri reads its size through `SAFDocumentFile.length()`, so the common case is weighed
before `bytesSync()` materializes anything. There is no bounded read to fall back on
for the rest — `File.open()`, `readableStream()` and `writableStream()` all reach
`FileSystemPath.javaFile`, which throws `This method cannot be used with content
URIs` outright, leaving `bytesSync()` as the only read a provider uri has and it is
all or nothing. So an item whose provider reports no size, which answers 0 and is
indistinguishable from an empty file, is refused rather than read at an unknown
size. An empty pick was nothing to stage either way.

(b) `getDocumentAsync` takes no selection limit, so the room `pick` hands it was
advisory and a user could return more than the registry holds. Counted before
staging: previously all nine assets were copied into the cache and `mint` refused the
lot, which the red run showed as nine discards. The refusal is
`native_media_handle_cap` and it sweeps nothing, because nothing of this shell's
existed yet.

Three pins, each red on its own mutation: dropping the unweighable refusal, making
the room check a no-op, and taking it off the Files arm.
