22 of src/tasks/'s 25 remaining raw-port files now send through a declared operation instead of
the raw request port: 70 references to 0, leaving 3 files and 3 references. No golden moved —
`git show --stat` on this commit touches nothing under mobile/rpc-foundation/, which is the
parity claim, and the 317 goldens recorded in the previous commit all pass against this tree.
56 operations over 58 methods, in five modules named for what they send: one item's detail
reads, the list's provider loads, item comments and replies, item state/merge/check writes, and
the GitHub Projects board. Five more operations are reused from the workspace-creation half
rather than redeclared, because the list asks github.listWorkItems, gitlab.listWorkItems,
linear.searchIssues, linear.listIssues and settings.update with the same acceptance the Smart
picker does.
Three methods carry two policies each, and all three pairs are named. `linear.status`: task
hydration cannot list without the workspace and surfaces the host's message, the home probe
degrades to "not connected". `linear.listTeams`: hydration reconciles a saved selection and
needs it, the composer's picker just empties. `github.repoSlug`: the Projects board must tell
"no slug" from "the ask failed" and caches the failure for retry, the paste lookup caches a
refusal as "no slug" and carries on. Each pair shares one reader, so no method has two. No new
acceptance policy.
Ten sites picked a method with a ternary. Nine were a literal pair — a provider or an item type
choosing between two methods — and each now selects between two operations instead, which also
types each arm's params separately. Two of those were listed as unmigratable `{ method, params }`
multiplexers: `use-mobile-tasks-project-file-merge-actions.tsx` and
`use-mobile-tasks-hosted-metadata-actions.tsx` both assign `method` and `params` from local
ternaries over `item.source.type` in the same function, not from a step a picker hands them, so
both migrated and both reach zero.
The Linear detail barrier keeps raw requests inside its `Promise.all`. main's group rejects as
soon as one leg's transport does, and interpreting only after both settled is what lets the
comments rejection win over the issue refusal — the b3 seed. `startRpcOperation` would wait for
the slower peer. Every loading hook's `stale` or generation guard stays where it was, between
the request and the state commit.
Two preserved oddities, both recorded rather than repaired:
- `gitlab.todos` keeps its payload spelled `response.result`. A reply that is neither an array
nor nullish crashes in `.map`, and the message the screen shows is that expression's source
text; renaming the local moved a golden, which is how this was found.
- `github.listWorkItems` keeps sending `before`. The list's pagination cursor is not in that
method's params schema, so the host has always dropped it and mobile's GitHub "load more"
re-asks for the same page. Sent verbatim with a cast; making the host honour the cursor is a
product fix with its own recording. Worth a ticket.
`github-project-host-routing-source.test.ts` pinned method literals that have moved into the
operation modules. It now pins the same guarantee in two halves — the board site carries the
host or the row's `prRepo`, and the named operation still sends that method — so neither half
can drift alone. The board's issue/PR update repeats its params rather than hoisting them, so
each send textually carries its own host, which is what that test reads.
The Mobile Tasks source-parity hashes move for the same reason the workspace half's did. The
diff is evidence rather than a re-pin: `semantics` is a pure deletion, 148 lines out and none
in — 70 `rpc:` call signatures, 75 method literals over 58 methods, and three duplicated
`item.source.type` comparisons that only existed because one `sendRequest` had to pick both a
method and a matching params shape from the same test. Statement, declaration, render and style
counts are unchanged, and the render, declaration and style hashes are byte-identical.
`b3: kills order` fails at this commit and only this commit. Its anchor names the send this
migration rewrote, so it matches zero sites; the next commit rehomes it at the same defect and
re-digests. Every other test passes.

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_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
