Brennan Benson 357a2fed08 fix(native-chat): group chat rows by the turn that produced them (#23671)
* fix(native-chat): keep a turn's bar on the prompt that opened it

A message sent while a structured turn runs appears in the transcript at
once, so "the newest user message" is not the running turn's owner. The
live "Working for" bar moved to the mid-turn message and counted from the
earlier prompt's start, and a send queued behind the running turn counted
its wait twice: once in the previous turn and again from its own send.

Derive both from the host's turn records in one ordered pass:
- The running turn's bar belongs to the user message its lifecycle row
  names (resolved exactly as settled timing resolves it). A message sent
  mid-turn gets no bar until its own turn opens; a send folded into the
  running turn never gets one. Surfaces fall back to the latest user
  message only when the host names no opener.
- A turn counts from its send, but never before the previous turn in the
  journal ended (its recorded end, else its row's last host revision),
  capped at the turn's own start. The same origin feeds the live counter
  and the settled duration.

Desktop and mobile share the derivation; no wire, host, or storage change.

* feat(native-chat): derive each transcript row's owning turn from the journal

Rows between a turn record and the next belong to that record's turn, so a
message the provider folds into a running turn no longer captures the rows
produced after it. A turn whose opener the host cannot name in the loaded
window anchors to its own record instead of a bystander prompt, and shared
nativeChatRowTurnKeys keeps positional preceding-user grouping for anything
the host does not attribute (older hosts stay pixel-identical).

* fix(native-chat): fold and time transcript rows by their owning turn on desktop

A settled turn's bar now folds every row the turn produced, including rows
after a mid-turn send; the steered bubble stays visible and carries no bar. A
provider-opened turn renders its bar above its first row instead of borrowing
the newest prompt, and row liveness follows the owning turn rather than the
newest user message, so a running turn's rows stay live while a send waits.

* fix(mobile): group phone transcript rows and bars by their owning turn

Same shared derivation as desktop: the opener's bar owns every row of its
turn across a mid-turn send, a steered bubble never grows a bar, a
provider-opened turn's bar sits above its first row, and a running turn's
tool rows stay live while a newer message waits behind it.

* fix(mobile): declare the turn ownership map on the chat controller contract

* fix(native-chat): one diff rollup per turn, and no wake-turn clock on a later prompt

A turn's rows are no longer contiguous once rows are grouped by owning turn: a
prompt sent before the running turn's last row lands among its rows. The diff
rollup was drawn at every run boundary, so such a turn showed its rollup twice
and the later prompt's rollup appeared under its bubble. It now renders once,
under the turn's last row.

On the phone, a turn keyed to its own record is not a user message, so when it
ended its clock was treated as a replaced optimistic echo and handed to the
newest prompt - a message sent during a wake turn got a bar with the wake turn's
duration. Host-attributed turn keys now count as live turn keys.

* fix(native-chat): keep a Codex turn's bar on its send until the echo lands

Codex reports turn/started before it runs hooks and prewarm and before it
echoes the send, so for that gap the turn names a provider key no alias
resolves yet. Anchoring it to its own record left the running turn with no
bar at all; treat the send still in flight ahead of the record as its opener.

* fix(codex): restore each turn's record ahead of that turn's items

Rows are grouped by the nearest turn record before them in journal order,
which holds on the live path because a turn's record is written when the turn
opens. Full-history restore (the fallback for Codex app-servers that reject
excludeTurns) wrote each turn's items first and its record after, so every
restored turn's rows were credited to the previous turn and turn 1's answer
folded away.

The restore now appends the record before the turn's items. The record itself
is unchanged: same identity, state, outcome, opener key, endpoints and
duration, one append each. The restore-order test now expects the record
first, because that order is what keeps grouping correct; its old order was
incidental, not a contract any reader relied on. Readers that key turns by id
or opener key, or that scan for the newest record (all restored records are
settled), read the same result in either order.

Journals already imported in the old order stay as written; no migration.

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.

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 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 — 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
