* test(mobile): record the terminal input surface before migrating it (step 4) Three families the recorder could not reach before, recorded against the pinned baseline's product code so the migration that follows has a parity oracle. The device state these hooks read is real, not declared. The pasteboard is the engine's existing per-recording fixture, so a paste reads the bytes a recorded copy put there one action earlier; the buffered draft store is the product's own useBufferedTerminalDrafts mounted in the same tree. No engine file is touched, so no existing golden moves and no header re-digests: 13 new goldens, 641 unchanged. Only the clipboard's text path is driven. The image path decodes a raster through expo-image-manipulator and stages it on expo-file-system, and recording it would mean inventing image and file-system behaviour. Both paths reach the same send. Two family mutants, one per family whose state() can observe a reply: keeping a refused send's draft cleared, and resolving the first repo's connection instead of the workspace's own. The paste family gets none — the hook returns void and calls onSuccess for an accepted and a refused send alike, so its only reply-dependent behaviour is the takeover report, which lives in the sender list. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * refactor(mobile): send the device-state holdouts through typed RpcOperations (step 4) Ten references over six files, the last of the raw-port sites whose blocker was that a recording could not reach them. Zero goldens move: every one of the six was recorded first, and the suite replays them against the rewritten code. Two operations are new and four sites reuse one that already fixes their method: - accounts.consumeCodexResetCredit, throw-message, payload unread — the call site's decodeResetResult is one scope-and-snapshot check and splitting it across a reader would put one refusal rule in two places. - notifications.getMissedSince, skip — a background pass with no screen to raise a host message on. The member read stays where the optional chaining was. - repo.list: the accessory's connection lookup joins the new-tab reader, which already threw the host's message; the new-workspace dialog joins the skip reader, which already left the list it had. Same reader, same policies, no new acceptance rule and no third operation on that method. - terminal.send: the composed send, the live keystroke send and the clipboard paste all join terminal.input-send, which the accessory raw send already used and which reads acceptance the same way isTerminalSendRpcAccepted did. The typed contract is stricter than the client's own scope type on the redeem: the catalog pairs each runtime with the distro it may name, while the shared CodexResetCreditExpectedScope does not. The invariant is real and held by the attempt journal's schema, so the narrowing is asserted at the send with that named; the bytes are unchanged. Widening the catalog would be a wire change. Two source-shape ratchets pinned the old call text and move with it. The route parity suite's runtime strings drop from 540 to 537: the three method literals that became operation definitions, and nothing else. Every hook, callback identity, effect, JSX and style pin is unchanged. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * docs(mobile): correct the terminalInputSend and PTY-mode holdout comments `terminalInputSend`'s doc still claimed two call sites. It now has five non-test consumers, all on the same acceptance: the query-reply responder, the live accessory raw send, the session screen's composed draft send and live keystroke send, and the clipboard paste. That comment is where the next person narrowing `object-result-or-null` learns whose lost-ack meaning they are changing, so it names all five and their files. The session inventory block closed with "opens or rides a subscription, or takes its method as a parameter", which no longer covers every holdout below it: `use-mobile-session-terminal-input.ts` is held out for a webview handle. Its own reason also said PTY mode was unavailable in the runner, which this branch's terminal-input adapter contradicts by fixturing the mode map a paste reads. The sentence is narrowed and the holdout restated: PTY mode is recordable, the live webview handle is what is left. Comments only. No product behaviour, no golden, no parity hash moves. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): pair the draft-restore mutant with the refused send `terminal-send-refusal-restores-draft` documents the harm of a refused send that leaves the composed draft cleared, but it was driven by the accepted scenario, where the kill comes from the inverse (a draft restored after a send that landed). The refused scenario shows the documented harm directly: without the restore the input stays empty after the runtime says no. Still one mutant per family, and it kills there — verified by running the suite, `terminal-input-send-refused: kills terminal-send-refusal-restores- draft`. No golden, no product change. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * docs(mobile): correct the gesture-input holdout and drop a dead repo type Three round-2 corrections, comments and one dead type; no behaviour. The gesture-input holdout claimed a recorder gap that does not exist. The flush path reads refs only — client, connection state, PTY modes, the gesture buckets, active handle and tab type — and the clear-buffer reference optional-chains the webview ref, so a mount with a null terminal ref puts both sends on the wire. The reason now says what is true: those 2 references are migratable as they stand and were out of this PR's bucket. The session summary sentence no longer offers a webview reason. `RuntimeRepoSummary` in mobile-session-route-types.ts lost its last consumer when the accessory hook moved to `MobileRuntimeRepoSummary`; `git grep RuntimeRepoSummary` now finds only the `Mobile`-prefixed type. Deleted. Both refreshed route-parity hashes still credited the `interpretOrThrowRefusalMessage` refresh for their current value. They now state the invariant they pin and this PR's reason for the move: the sends and repo reads inside those bodies name their `RpcOperation` instead of the raw `sendRequest` port.

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
