Jinwoo Hong 7cf09809f6 fix(mobile): group by Project with the desktop sidebar's own code (#28850)
* fix(mobile): phone server rows follow the desktop's other-client and sleeping filters

A phone created through a desktop now records whom it acted for, so the
desktop's Hide other-client workspaces filter keeps the user's own phone
workspaces (locally and on servers) and hides only other people's.
The desktop relay marks each server row its sidebar would hide, and the
rows its own browser or chat tabs keep awake; the phone applies both.

* test(e2e): dedupe sidebar row ids in the visibility spec

* fix(mobile): address review: owner naming, old-server relayed phones, scope trim

* refactor: move the sidebar's project section grouping into shared

The project sections the desktop sidebar draws under Group by Project are
built from the project/setup projection, the per-host catalog fold, the
endpoint host stamp, and the section labelling and ordering rules. Move the
pure parts of each into src/shared (no behaviour change) so the paired phone
can call the same code instead of guessing the grouping.

* fix(mobile): group by Project with the desktop sidebar's own sections

The phone grouped Project sections by repo display name, so it merged
checkouts the desktop keeps apart (several local stablyai/orca checkouts,
or a server's copy) and split what the desktop merges. The phone now reads
each host's repo.list, project.list and projectHostSetup.list (the desktop's
own and each server's through the relay), folds them with the renderer's
shared catalog fold and projection merge, and builds sections with the
desktop's shared grouping, labelling and ordering code. Keys, labels and
Recent order equal the sidebar's; a host that predates the project lists
gets the repo-derived projection, as the desktop does.

Header colour and icon come from the section's anchor repo and rows from
their own repo by id, as on the desktop. The repo filter lists every
catalog repo by id per host instead of merging same-named repos. Group-by
labels read Project and None. project.list and projectHostSetup.list are
routed for paired phones (read-only, workspace permission).

* refactor(mobile): record a phone's owner as creator and fold desktop tab activity into the host flag

A phone now records its owner as the creator (this host for a directly
paired phone, the relaying desktop for a delegated one), so the shared rule
is unchanged and onBehalfOf is gone. The relay ORs the desktop's saved
browser/chat tabs into hasHostSidebarActivity, so the phone's status dot
follows too, and local worktree.ps counts the same signals. The old-server
fallback is removed.

* test(e2e): poll the phone and the sidebar together in the visibility spec

* fix(mobile): one Project-section builder for desktop and phone, with the desktop's repo order

Review fixes. The sidebar's buildOrderedGroups now calls the shared
buildProjectSections for Group by Project (notice and pending repos are
optional inputs), so desktop and phone run one function. The phone ranks
manual header order by its folded catalog order, which is each host's
repo.list order with the desktop's own repos first, as the renderer loads
them; only the desktop's cross-host manualRepoOrder (pairing-local) is
unknown to it. The projection selector is now a memo over the shared
resolver. A transient project-list failure keeps that host's last catalog;
only forbidden or method_not_found falls back to the repo-derived
projection. Catalog rows are checked on every member grouping reads, and
the parity test answers the renderer's real catalog fetch, includes a
server's own project rows, and fixes Manual and Recent orders that differ.

* fix(mobile): use the repo-derived catalog until a host's project lists first answer

* fix(mobile): the desktop serves its sidebar's Project catalog instead of the phone fetching it

The phone fetched repo.list, project.list and projectHostSetup.list from
the desktop and every relay-ready server each minute and folded them
itself, so rows from offline or older servers fell back to repo sections
and keys moved on cold start.

The desktop renderer now publishes the inputs its own Project headers use
(state.repos in sidebar order, the projection selector's projects and
setups, projectOrderBy) on the runtime window graph it already sends to
main, only when they change. Main keeps the last one and answers it on a
new paired-desktop read, mobileRelay.projectSections. The phone reads it
with its repo metadata and groups with the shared builder; a desktop that
predates the read (forbidden or method_not_found) leaves the phone grouping
rows by repo from the desktop's repo.list, and a transient failure keeps
the last catalog. The payload carries only grouping and label fields, no
hooks, credentials or uploaded icons. The phone's own catalog fetching and
its project.list/projectHostSetup.list routes are removed.

* fix(mobile): keep uploaded repo icons on the phone, and isolate the snapshot tests

* test(e2e): the desktop window serves its sidebar's Project catalog to the phone

* chore(i18n): regenerate the runtime English catalog (drift already on main)

* fix(mobile): read the Project catalog as its own request, outside the recorded repo-metadata flow

The extra read inside the repo-metadata refresh stalled its recorded RPC
sequence. It now runs beside it with its own throttle. The repo-metadata
goldens are re-recorded for the intended state change: the name-keyed
colour, icon and id maps became desktopRepos.

* fix(mobile): fetch the Project catalog at once when the screen moves to another host

The refresh window is now kept per client, so a host screen reused for another desktop doesn't wait out the previous host's 60s window before showing its Project headers.

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 port 8081.

Unless a command says otherwise, run mobile app commands from the mobile/ directory.

The Node commands pnpm rpc:diff and pnpm rpc:record use a development dependency linked to ../src/packages/process-host. Mobile's install supplies the link, and tsx runs its source with the orca-source condition, so these command wrappers do not require a desktop install or package build. Keep that source directory in sparse checkouts. The recording suites still need root dependencies when they exercise desktop modules. The React Native app does not import this host package.

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

  1. Open Orca desktop.
  2. Go to Settings > Mobile.
  3. Scan the pairing QR code from the mobile app.
  4. 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

  1. Install Expo Go from Google Play
  2. Run pnpm start, scan QR with Expo Go
  3. For native modules: pnpm exec expo run:android
  4. Run with pnpm start --dev-client

iOS Simulator

  1. Install Xcode from the App Store
  2. Run pnpm start --ios to 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 run check:tests-typecheck
pnpm lint
cd ..
pnpm typecheck:node

tsc --noEmit reads tsconfig.json, which excludes test files so Metro never bundles them. tsconfig.test.json puts them back, and pnpm run typecheck:tests shows their errors in full. check:tests-typecheck is the gate over it: a ratchet against tests-typecheck-baseline.txt, the 127 test files that do not typecheck yet. It fails when a file that checks today stops checking, and when a baseline entry starts checking (prune it with node scripts/check-tests-typecheck-ratchet.mjs --prune). The list may only shrink.

The same gate censuses the program first: every *.test.ts(x) on disk must be in it, or named in the script's TESTS_OUTSIDE_PROGRAM with a reason. Without that, a test excluded from tsconfig.test.json — or a Foo.test.tsx shadowed by a Foo.test.ts beside it, which a wildcard include drops for the higher-priority extension — would leave the ratchet silently.

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_VERSION
  • mobile/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 the update that clears it. When mobile is too old it opens the newest release if the installed app's update check knows one, otherwise the App Store (iOS) or GitHub Releases (Android). When desktop is too old it opens GitHub Releases.

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 — with MOCK_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 omits transcriptPath to 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 (default orca-mock-send-mode in the system temporary directory) — accept (default) accepts the send, error fails it with mobile_input_floor_unavailable, anything else reports the send as rejected.
  • MOCK_TERMINAL_LIST_MODE_FILE (default orca-mock-terminal-list-mode in the system temporary directory) — omit returns an empty terminal list, other returns a list that omits the chat handle, anything else lists it.
  • MOCK_TERMINAL_STREAM_MODE_FILE (default orca-mock-terminal-stream-mode in the system temporary directory) — dead answers a subscribe with subscribed then end (a gone PTY), which is what exercises the rearm bound and terminal prune; anything else streams normally.

Connecting to Real Orca

  1. Start Orca desktop with WebSocket transport enabled
  2. In Orca, go to Settings > Mobile and scan the QR code with this app
  3. The QR encodes the connection endpoint, device token, and TLS fingerprint
