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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Inert for native phones: they never fetch it.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(mobile): start a new flow when the shell view remounts

A remount cleared `pageReady` but left the flow alone, so the wait the retired
document armed still matched. It expired onto the page that replaced it, took a
ready workspace to `document-load-failed`, and deleted the generation on the way.

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

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

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

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

* test(mobile): pin the ready deadline to the page's own retry ceiling

The margin was stated in a comment and asserted against itself, so changing
either number left the suite green.

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

C1.1's per-kind log lands on a branch that also refuses a route, and that
diagnostic was still falling through to the line about a view outliving its
host. It names the shell's own bug now, and carries the issue.

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

* fix(mobile): refuse a dot segment however the route spells it

A URL parser percent-decodes a path before it resolves it, so `/h/%2e%2e/x`
climbed out of the `/h/` prefix exactly as `/h/../x` does and landed the page on
a screen nobody asked for, with no refusal anywhere. The one segment rule both
patterns share now reads the encoded spellings as the dot segments they are, and
still lets an escape inside a name through.

* test(mobile): name routes in the manifest field list the builder emits

C1.3 added `routes` to every manifest this builder writes, and the Phase A
contract test still listed eight keys, which is what went red in CI.

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

* test(mobile): hold a navigate target to the same segment rule as the shell's

The href pattern is built from the segment source C1.2 tightened, and nothing
said so: a spelling one pattern refused while the other took it would be a hole
with a `notify` already pointed at it.

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

* test(mobile): give the ref-refresh probe the navigations this branch added

C1.1's new case builds its own probe, and on this branch a probe also collects
the hrefs the page hands back. The file stopped typechecking on the merge, which
the tests ratchet caught.

* style(mobile): format the web shell route entry

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

* test(mobile): split the bridge frame suite along the modules the merge created

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

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

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

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

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

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

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

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

Jinwoo Hong 9641a1b544 feat(mobile-web-bundle): serve the packaged mobile web bundle over RPC (OTA phase A, 3/5) (#21348)
* feat(mobile-web-bundle): serve the bundle manifest and chunks over RPC

Two paired-runtime methods on the already-authenticated connection:
`mobileWeb.bundle.manifest` returns this install's manifest plus the chunk
size it advertises, and `mobileWeb.bundle.chunk` returns one aligned range of
one asset with the whole asset's length and hash, so a single chunk describes
what it belongs to.

`path` is accepted only by exact match against a manifest member, so traversal
is unreachable rather than mitigated. Each asset's on-disk sha256 is verified
once and the verdict remembered, concurrent first readers sharing one hash.
Reads are capped at four in flight per connection, and a disconnected client
stops costing reads at the next checkpoint.

No SSH or relay proxying: a runtime answers only out of its own install.

* test(mobile-web-bundle): pin the three buildId serializers against each other

The canonical serialization exists in the builder, the packaging guard, and the
shared contract, because the two packaging scripts run on bare node before any
build output exists and cannot import TypeScript. A divergence in any one would
reject every honest bundle at packaging, or ship a bundle whose id the phone
recomputes differently and re-downloads forever. Proved red by swapping the
guard's code-unit sort for localeCompare: five of six cases fail.

Exports the guard's serializer for the test; no packaging behaviour changes.

* test(mobile-web-bundle): cover every error code and a multi-chunk paging round trip

Against a synthetic bundle in a temp dir, because the real builder's largest
asset is under one chunk and CI unit jobs never build out/mobile-web. The
fixture's script spans three chunks, its stylesheet is exactly one, and one
asset is empty, so paging, the eof boundary, and the zero-byte case are
exercised rather than assumed.

Reads in flight are held by latching `open`, so the four-per-connection cap and
an abort arriving mid-read are deterministic rather than a race with a
stopwatch. Both were proved red: dropping the abort check after verification
fails the abort case, and keying the cap on connectionId alone fails the
device-token case.

* fix(mobile-web-bundle): resolve the bundle root through the AppEnvironment port

check:runtime-electron-ratchet caught this: the resolver sat beside
getBundledWebClientRoot in src/main/startup and imported electron, and importing
it from an RPC method pulled the first electron edge into a runtime graph whose
baseline is zero. The runtime has to stay bootable on plain Node.

So it reads app.getAppPath() through the port every other runtime module already
uses, and moves next to its two callers under src/main/runtime. A host with no
environment installed has no install root, which is the same answer as having no
bundle. orcad answers getAppPath from its own install root, so a headless
runtime that carries the artifact serves it with no special case.

* fix(mobile-web-bundle): keep filesystem failures inside the six error codes

An asset unlinked or truncated after its verdict was cached reached the client as
runtime_error carrying the desktop's absolute install path. Both now answer
mobile_web_bundle_asset_changed, with the cause warned host-side only. A short
positional read is the truncation case, so it throws instead of paging the client
past the end.

The dispatcher substitutes `{}` for absent params, so `z.null()` could never
parse; the method declares `params: null` instead. A comment on the method name
records why there is no schema.

* fix(mobile-web-bundle): fill the read window instead of failing a partial read

fs.read may answer short of what it was asked for before EOF, so the previous
check turned a legitimate partial read into a spurious asset_changed. The loop
mirrors the relay's readFullStreamChunk, which is not imported because it sits
behind the relay dispatcher's module graph; only a read returning nothing is
treated as truncation.

* refactor(mobile-web-bundle): read the disconnect idiom with the shared predicate

isClientDisconnectedError already exports exactly the check the catch needed, so
the local error class goes away and the throw returns to the repo-wide idiom. The
module doc now says asContractError is a total catch.

* test(mobile-web-bundle): pin the four branches no test was holding

Each one survived a mutation: the abort check before verification, the
per-process manifest cache, the buildId component of the verdict key, and
delete-at-zero in the admission map. The last two matter beyond hygiene — a
verdict keyed by path alone carries a failed verdict onto the next build of
index.html, and a map that never drops a key retains one pairing token per
socket.
