* refactor(mobile-recorder): one shared write ordinal for requests, payloads and effects
`sent` stamped each payload and effect with the number of requests sent at
write time, which orders those two lists against sends but never against each
other. A family that sends no requests therefore had every stamp at `0`:
moving `host-worktree-refresh.ts`'s two initial snapshot reads from after
`client.subscribe` to before it moved none of the 705 goldens.
One monotonic counter per recording now stamps requests, payloads and effects
alike at the moment each is written, so the three append-only lists are ordered
against each other. The same reorder now fails five goldens. A request is
stamped at the logical `sendRequest` call rather than when its physical payload
is published, so a send that waited for connected carries two distinct stamps.
Full re-record from the pinned baseline: 699 bodies moved, 6 header-only,
0 added, 0 deleted; the only moved JSON paths are `sent` leaving and `ordinal`
arriving on `sender`, `payloads` and `effects`. Decoding with those two fields
stripped leaves all 705 header-only.

* feat(mobile-recorder): observe streams still registered at teardown
Closing a stream only writes to the wire when its method has an unsubscribe
builder. `notifications.subscribe` has none, so a cleanup that forgets its
local `unsubscribeStream()` leaks a live registry record and nothing on the
wire changes. Until now that class was covered by one hand-written scenario
per method, which stops the stream and cuts over so the leak reappears as a
second subscribe payload.
Teardown now asks each session's `RpcClientStreamRegistry` what it still holds,
after the product's cleanup and before the transport disposes it, and records a
non-empty answer as a `streams-registered-at-teardown` effect carrying each
stream's method, subscribe payload and cancelled flag. The set is read off the
registry's own map: a mirror kept by the recorder would reproduce the product's
bookkeeping rather than observe it. Deleting `unsubscribeStream()` from
`mobile-notifications.ts` fails 7 goldens now, against 1 before.
Re-record: 4 bodies moved, 701 header-only, 0 added, 0 deleted. All four are
the two `runtime.clientEvents.subscribe` matrices, on partitions whose subscribe
reply is not a well-formed `ready`: with no subscription id to unsubscribe with,
the registry deliberately holds the cancelled record, which is why the
observation carries `cancelled`.

* refactor(mobile-recorder): one host-client context exposure, anchored on the product source
Five adapter modules each carried `exports.recorderHostClientContext = Ctx;`
inside a source string appended to `client-context.tsx`. `Ctx` is a
module-private local, so the reference lives in a string no type checker
follows: renaming it typechecks clean and fails a recording with a
`ReferenceError` a hundred seconds in, five times over.
`hostClientContextExposure` and `loadHostClientContext` are the one copy, and
`adapter-seam.test.ts` asserts the declaration the exposure names still exists
exactly once in `client-context.tsx` and refuses a sixth inline copy. A rename
remains invisible to `tsc` — nothing but editing the fenced product module
makes a private local checkable — so the anchor is what turns it into one
failure that says what moved.
Also splits the subscription tests out of `recording-runner.test.ts`, which
items 1 and 2 had pushed past `max-lines`.
Re-record: 705 header-only, 0 bodies moved, 0 added, 0 deleted; `recorderSha256`
on all 705 and `adapterSha256` on the 23 goldens mounted through the five
modules.
Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
* feat(mobile-recorder): record what a checked read salvaged
`collectSalvageDrops` builds a report on every decoded reply — which array
elements a `salvagingArray` threw away, which members a `salvagedOptional`
read as absent — and `classifyRpcReply` puts it on the outcome, where nothing
reads it. Which rows a reply lost was therefore visible nowhere, including in
a golden.
The recorder wraps `classifyRpcReply` on the mounted module, the one seam every
checked read passes through and the only one that knows the operation the drop
happened under, and records a non-empty report as a `reply-salvage` effect. No
product code changes; the report was already being built and discarded.
No golden carries one. All 19,384 checked reads in the corpus decode their reply
whole, because the reply matrix varies the envelope a host sends rather than the
shape of a row inside a result. The observation pins that absence, and moves the
first time a narrowed element or member schema drops a recorded row — including
where nothing downstream reads it. `salvage-observation.test.ts` is what keeps
the observation honest, driving a malformed row and a malformed optional through
the real `git.status` reply schema.
Re-record: 705 header-only on `recorderSha256`, 0 bodies moved, 0 added,
0 deleted.

* fix(source-control): let hostedReview.create carry a provider token this build does not list
`HostedReviewCreate.provider` was a closed `z.enum`, so a client repeating back
a provider a newer host named in its own eligibility reply had its create
rejected at params validation. Mobile worked around it with a SAFETY-annotated
assertion: narrowing to `'unsupported'` before sending would have made the host
refuse its own provider, so the token was cast through instead.
The schema member is now `z.string()`, and both create handlers narrow through
`supportsHostedReviewCreation` before calling the runtime, so an arm this build
does not know answers `unsupported_provider` with readable copy rather than a
params error the client cannot act on. `createHostedReview`'s own refusal is
the single source of that copy. The mobile assertion is deleted.
Product change on a fenced path, so the goldens are not re-recorded: the whole
recording suite replays green against the corpus committed in the previous
commit, 825 passed, zero golden movement.

* test(source-control): annotate the runtime stub cast in the provider refusal test
The changed-code quality gate counts a new `as unknown as OrcaRuntimeService`
as a finding. A narrower stand-in does not exist: the interface has 1047
members and `Pick` of the three this test uses is not assignable.

* fix(mobile-recorder): pay React's lazy Math.random draw before the seeded run
React resolves `enqueueTask` by reading `module['require' + Math.random()]` and memoizes the
result, so a process draws exactly one `Math.random()` the first time it awaits `act`. The runner
drains through `act` after every step, so that draw landed inside whichever recording ran first and
ate the seeded sequence's first value: a family recording a `Math.random()`-derived param recorded
one value when it ran alone and a different one when it ran after any other family, and an adapter
could only dodge it by drawing in its factory ahead of the first drain.
The scheduler now pays that draw once per process, before it installs the seeded generator, so the
seeded sequence starts at the same value for every recording. Priming is awaited, which makes
`start` async.
Goldens re-recorded: 705 header-only, `recorderSha256` alone. No golden carried a first-in-process
value, so nothing moved in a body.
Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
* fix(mobile-recorder): drain before reading the streams left at teardown
The teardown observation read the registry after `dispose()` returned but before the scheduler
drained, so a cleanup that closes its stream on a due 0ms timer had not run yet and was recorded as
an uncancelled registration — the one shape this observation reserves for a cleanup that never ran.
A deferred close and a stream nobody ever closed were byte-identical.
The drain now runs before the read, with the transport still disposed after it. A second drain stays
after disposal: tearing the registries down rejects what the product still awaited, and an unhandled
rejection is an effect the cleanup checkpoint has to see.
Also: the registry size comparison in `registeredStreams()` could never fire, because `size()`
returns `this.streams.size` on the same object; `RECORDER_HOST_CLIENT_CONTEXT` is used only in its
own module and no longer exported; and `streamPayloads` now says what it holds, which is every frame
the registry publishes rather than only subscribes.
Goldens are stale in this commit and are re-recorded in the next one.

* test(mobile): re-record the corpus after the baseline repin and the teardown drain
Recorded from a detached worktree pinned at 97aa5ff19b with this branch's recorder laid over it,
because two fenced product files still differ from the pin: the `hostedReview.create` provider
widening in `src/shared` and the mobile assertion it removes. `--record` in place refuses on that,
by design. A control run of the same harness with main's own recorder reproduced main's 705 goldens
byte-for-byte first, so anything below is attributable to this branch.
Against main, with `sent` and `ordinal` stripped: 701 header-only, 4 body moved, 0 added, 0 deleted.
The four are the two `runtime.clientEvents.subscribe` matrices already disclosed. Moving the drain
above the teardown read moved nothing: every non-empty set in the corpus is a cancelled record
waiting on a subscription id no drain can deliver.
Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
* fix(mobile): restore the type imports the recorder test split dropped
`subscription-recording.test.ts` annotated a mount with `RpcClient` without
importing it: vitest strips the annotation and mobile's tsconfig excludes
`**/*.test.ts`, so neither gate saw it. Typechecking the two moved suites under
a throwaway config that includes them also surfaced `sampleGolden` missing the
`adapterSha256` header the format has required since version 5.
The README's teardown claim is scoped to a due timer, since `flush()` only runs
work due at the current virtual time and a later timer is still registered at
the read.
Neither file feeds `recorderSha256`, so the corpus is unchanged.
Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
* test(mobile): scan the engine directory for a sixth exposure copy
The sixth-copy guard read only `adapters/`, so an inline copy appended to an
adapter failed and a new file under `adapters/` failed, but the same literal in
an engine file passed every assertion. Scan both directories, TypeScript
sources only, since the README quotes the string to document it.
`host-client-context-exposure.ts` holds the template with its interpolations
rather than the literal, so it still cannot match itself; a throwaway engine
file carrying the literal fails the test, and the file is otherwise green.
Also narrows the register's import statements before reading `moduleSpecifier`,
which drops a non-null assertion and the two TS2339 errors the `**/*.test.ts`
exclude was hiding.

Orca Mobile
React Native companion app for Orca. Monitor worktrees, view terminal output, and send commands from your phone.
Local development uses two processes:
- Orca desktop/Electron from the repo root. This hosts the mobile WebSocket RPC server on port
6768. - Expo Metro from
mobile/. This serves the React Native app on port8081.
Unless a command says otherwise, run mobile app commands from the mobile/ directory.
Prerequisites
- Node.js 24+
- pnpm
- Xcode and/or Android Studio tooling for simulator or device builds
- Expo Go on your phone, or a development client build when native modules are needed
- Phone and desktop on the same LAN when testing a physical phone
Start Desktop Orca
From the repository root:
pnpm install
pnpm dev
Confirm the mobile RPC server is listening:
lsof -nP -iTCP:6768 -sTCP:LISTEN
Restart pnpm dev after changing Electron main-process code. Metro hot reload only applies to the mobile JavaScript bundle.
Start The Mobile App
cd mobile
pnpm install
pnpm start
Scan the Expo QR code with your phone's camera on iOS, or Expo Go on Android.
For a native dev-client build:
pnpm exec expo run:android
pnpm exec expo run:ios
pnpm start --dev-client
Pair With Desktop Orca
- Open Orca desktop.
- Go to Settings > Mobile.
- Scan the pairing QR code from the mobile app.
- Confirm the mobile host endpoint is
ws://<desktop-ip>:6768.
For the Android emulator, use ws://10.0.2.2:6768. For a physical phone, use the desktop LAN IP, for example ws://192.168.0.179:6768.
If the phone has a stale host entry, remove it from the app and pair again.
Development Paths
Android Phone
- Install Expo Go from Google Play
- Run
pnpm start, scan QR with Expo Go - For native modules:
pnpm exec expo run:android - Run with
pnpm start --dev-client
iOS Simulator
- Install Xcode from the App Store
- Run
pnpm start --iosto open in iOS Simulator
Physical Phone Debugging
The phone can be inspected through the connected device tooling:
orca snapshot --json
orca click --element @e3 --json
orca fill --element @e1 --value "ls" --json
orca screenshot --json
Use snapshot first to find the current element refs, then click/fill those refs. After mobile file edits, Metro usually hot reloads automatically, but navigating out of and back into the session screen can be useful because it re-runs terminal.subscribe.
Terminal Streaming Repro Without A Phone
Use this when terminal output does not render on device and you need to split server streaming bugs from WebView/UI bugs:
cd mobile
ORCA_MOBILE_WS_URL=ws://127.0.0.1:6768 pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64>
You can pass a worktree selector as the third argument:
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "id:<worktreeId>"
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "path:/absolute/worktree/path"
pnpm exec tsx scripts/test-subscribe.ts <deviceToken> <serverPublicKeyB64> "name:my-worktree"
The expected result includes:
streamSawMarker: true
readSawMarker: true
If this repro fails, debug the desktop runtime/PTY path before the mobile WebView. If it passes but the phone is blank, debug the session screen or TerminalWebView readiness/queueing path.
Terminal Color Repro Without A Phone
Use this when terminal colors disappear after switching tabs. Open a Claude Code terminal and at least one other terminal in the target worktree, then run:
cd mobile
ORCA_MOBILE_WS_URL=ws://127.0.0.1:6768 pnpm exec tsx scripts/repro-terminal-colors.ts \
<deviceToken> <serverPublicKeyB64> "id:<worktreeId>"
The script captures terminal.subscribe snapshots in an A → B → A sequence and writes raw snapshots to mobile/terminal-color-repro/. If the two A snapshots have different sgrColor counts, the desktop snapshot changed during the switch. If they match, the ANSI color data is still present and the bug is in mobile replay/rendering.
Validation
Run these checks before committing mobile terminal changes:
cd mobile
pnpm exec tsc --noEmit
pnpm lint
cd ..
pnpm typecheck:node
Protocol Version Compatibility
Mobile and desktop talk over a versioned protocol. Because mobile updates lag desktop by 24-48h via the App Store, both sides exchange version numbers on status.get so a genuinely incompatible combo can hard-block instead of silently misbehaving.
Constants live in two files (Metro can't resolve outside mobile/):
src/shared/protocol-version.ts—DESKTOP_PROTOCOL_VERSION,MIN_COMPATIBLE_MOBILE_VERSIONmobile/src/transport/protocol-version.ts—MOBILE_PROTOCOL_VERSION,MIN_COMPATIBLE_DESKTOP_VERSION
Today all four are set so evaluateCompat always returns { kind: 'ok' } — nothing blocks. The wire format is in place to flip a switch when needed.
When to bump
Bump DESKTOP_PROTOCOL_VERSION (and the mobile mirror MOBILE_PROTOCOL_VERSION when relevant) for breaking changes:
- Removed RPC method or required parameter that mobile uses
- Changed meaning (units, nullability) of an existing field mobile reads
- Changed encryption, framing, or auth handshake
Do not bump for additive changes:
- New RPC methods
- New optional fields on existing methods
- New event types in
terminal.subscribe
Set MIN_COMPATIBLE_MOBILE_VERSION (kill-switch) when desktop ships a change that requires a minimum mobile version to function safely. Same for MIN_COMPATIBLE_DESKTOP_VERSION from the mobile side.
When a verdict is blocked, mobile/src/components/ProtocolBlockScreen.tsx renders a screen pointing the user at either the App Store (mobile too old) or GitHub Releases (desktop too old).
To exercise the block screen locally: set MIN_COMPATIBLE_DESKTOP_VERSION = 999 in mobile/src/transport/protocol-version.ts, rebuild, pair to any desktop. Revert before merging.
Mock Server
Develop the mobile app without a running Orca desktop instance:
pnpm mock-server # starts mock WebSocket server on port 6768
Connect from the app using endpoint ws://localhost:6768 and token mock-device-token.
Environment variables
MOCK_NATIVE_CHAT=1— serve the native-chat scenario (one live agent tab, empty transcript, image upload) instead of the default terminal fixtures.MOCK_CHAT_AGENT=omp— withMOCK_NATIVE_CHAT=1, present an OMP tab and four decoded transcript messages, including a tool call and result, instead of the default Claude scenario. It deliberately omitstranscriptPathto exercise legacy-hook readability discovery; current OMP hooks may report a path.MOCK_SERVER_KEY_FILE— persist the server keypair across restarts so a paired device keeps its public-key pin. A missing or invalid file is re-keyed with a warning, which forces a re-pair.
Scenario control files
Read on every request, so behaviour can be flipped mid-session without a restart (a restart would re-key E2EE and force a re-pair). Write the mode into the file, or delete it for the default.
MOCK_SEND_MODE_FILE(defaultorca-mock-send-modein the system temporary directory) —accept(default) accepts the send,errorfails it withmobile_input_floor_unavailable, anything else reports the send as rejected.MOCK_TERMINAL_LIST_MODE_FILE(defaultorca-mock-terminal-list-modein the system temporary directory) —omitreturns an empty terminal list,otherreturns a list that omits the chat handle, anything else lists it.MOCK_TERMINAL_STREAM_MODE_FILE(defaultorca-mock-terminal-stream-modein the system temporary directory) —deadanswers a subscribe withsubscribedthenend(a gone PTY), which is what exercises the rearm bound and terminal prune; anything else streams normally.
Connecting to Real Orca
- Start Orca desktop with WebSocket transport enabled
- In Orca, go to Settings > Mobile and scan the QR code with this app
- The QR encodes the connection endpoint, device token, and TLS fingerprint
