+# Android Emulation — Live Pane Streaming
+
+The Android **control** path (device list, boot, tap/type/buttons/rotate/exec,
+install/launch/permissions/ax/logcat) is complete and unit-tested. This document
+covers the **live H.264 video pane** (scrcpy + WebCodecs), which requires the
+Android SDK, a running AVD, the bundled `scrcpy-server.jar`, and Electron's
+WebCodecs runtime for end-to-end validation.
+
+## What is built (committed)
+
+| Module | Tested | Notes |
+|---|---|---|
+| `android/scrcpy-control-protocol.ts` | ✅ unit | Byte-exact control encoders (touch/key/text/back). |
+| `android/scrcpy-video-frame-parser.ts` | ✅ unit | scrcpy v2.4 codec-meta + frame-header parsing. |
+| `android/scrcpy-server-deploy.ts` | ✅ unit | push / forward / server-start arg builders. |
+| `android/scrcpy-stream-session.ts` | live-validated | Owns the server process + video/control sockets. |
+| `emulator/scrcpy-video-registry.ts` | ✅ unit | Pub/sub bridging a session to renderer subscribers. |
+| `ipc/emulator-video-stream.ts` | registration tested | `emulator:videoStream*` IPC; registered in `register-core-handlers`. |
+| `emulator-pane/use-emulator-video-stream.ts` | live-validated | WebCodecs `VideoDecoder` → `<canvas>`. |
+
+## Current wiring
+
+### 1. `scrcpy-server.jar`
+
+The version-pinned server jar must match `SCRCPY_SERVER_VERSION` in
+`scrcpy-server-deploy.ts`. Runtime resolution checks the packaged resource and a
+development fallback.
+
+### 2. `AndroidEmulatorBackend.startSession`
+
+`startSession` ensures the target is booted, resolves the bundled server jar,
+starts `ScrcpyStreamSession`, and feeds `scrcpyVideoRegistry`. A
+`createStreamSession` option lets unit tests inject a fake because the real
+session does socket I/O.
+
+```ts
+async startSession(deviceId: string): Promise<EmulatorSessionInfo> {
+  const serial = await this.ensureBooted(deviceId)
+  const jar = resolveScrcpyServerJar()
+  if (!jar) {
+    throw new EmulatorError('emulator_helper_failed', 'scrcpy-server.jar not bundled (see docs/android-emulation-streaming.md).')
+  }
+  const session = await (this.createStreamSession ?? ScrcpyStreamSession.start)(
+    { runner: this.runner, sdk: this.requireSdk(), serial, localJarPath: jar, maxSize: 1024 },
+    {
+      onMeta: (meta) => scrcpyVideoRegistry.pushMeta(serial, meta),
+      onFrame: (f) => scrcpyVideoRegistry.pushFrame(serial, { config: f.config, keyFrame: f.keyFrame, pts: String(f.pts), bytes: toArrayBuffer(f.data) }),
+      onError: () => scrcpyVideoRegistry.stop(serial),
+      onClose: () => scrcpyVideoRegistry.stop(serial)
+    }
+  )
+  scrcpyVideoRegistry.register(serial, () => session.close())
+  this.streamSessions.set(serial, session)
+  return { deviceUdid: serial, streamUrl: `scrcpy://${serial}`, wsUrl: '', streamCodec: 'h264' }
+}
+```
+
+`stopHelperForDevice(serial)` stops the registry and closes the stored session.
+
+### 3. Low-latency input via the scrcpy control socket (optional refinement)
+
+Input already works via `adb shell input`. For smooth multi-touch, when a live
+session exists, route `tap`/`gesture` through `session.sendControl(...)` using the
+encoders in `scrcpy-control-protocol.ts` (convert normalized coords →
+device pixels with `android-input-mapping`, then `encodeInjectTouchEvent`).
+
+### 4. Preload + pane
+
+- **Preload** (`src/preload/...` emulator API): exposes `startVideoStream`,
+  `stopVideoStream`, `onVideoStreamMeta`, `onVideoStreamFrame` wrapping the
+  `emulator:videoStream*` channels (mirror the existing `startFrameStream` etc.).
+- **Pane** (`emulator-screen-stream-content.tsx`): when
+  `session.streamCodec === 'h264'`, renders the `<canvas>` from
+  `useEmulatorVideoStream(deviceId, enabled)` instead of the MJPEG `<img>`.
+- **Hardware buttons** (`emulator-phone-hardware-buttons.tsx`): includes Android
+  variants (Back, Home, Recents, Power, Volume) selected by backend kind, per
+  `docs/STYLEGUIDE.md`.
+
+### 5. Validate on hardware
+
+```sh
+pnpm build:cli
+# boot an AVD (Android Studio or `emulator @<avd>`), then:
+orca-dev emulator devices --json          # see the device
+orca-dev emulator tap 0.5 0.8 --device <serial>   # control works today
+# after wiring §2/§4: open the emulator pane and confirm the live frame + taps.
+```
+
+## Risks to validate first
+
+- **WebCodecs H.264 in Electron**: confirm `VideoDecoder.isConfigSupported({ codec: 'avc1.640028' })`. If unsupported, fall back to a wasm decoder (Broadway/tinyh264) or a main-process H.264→JPEG transcode into the existing MJPEG channel — neither changes the backend interface (it advertises the codec).
+- **scrcpy server protocol/version**: the option set + handshake in
+  `scrcpy-server-deploy.ts` / `scrcpy-stream-session.ts` are pinned to v2.4 and
+  must match the bundled jar.
+- **Annex-B vs avcC**: the renderer configures the decoder without a description
+  (Annex-B). If frames don't decode, extract the avcC from the config packet.

+# Android Emulation
+
+## Problem
+
+Orca ships a built-in mobile emulator surface (live pane + `orca emulator` CLI +
+agent skill), but it is **iOS Simulator only and macOS only**:
+
+- `src/main/emulator/emulator-availability.ts:32` hard-returns "unavailable" for
+  any `platform() !== 'darwin'`, so Windows and Linux users get nothing.
+- The backend (`src/main/emulator/emulator-bridge.ts`) is wired directly to
+  `serve-sim` (`serve-sim-*.ts`) and `xcrun simctl`
+  (`simctl-simulator-devices.ts`), both Apple-only tooling.
+
+Android emulators run on Windows, Linux, and macOS via the Android SDK that
+Android Studio installs. We want Android emulation as a first-class peer of the
+iOS feature: full AVD lifecycle management, a live ~60fps pane, the full
+tap/gesture/type/button/rotate control surface, accessibility tree, app
+install/launch, runtime permissions, logcat, plus a dedicated
+`orca-emulator-android` agent skill.
+
+## Current architecture (what we reuse vs. replace)
+
+The existing stack already separates a backend from everything above it. The
+renderer pane, session registry, RPC/CLI shape, and tab system are effectively
+**backend-agnostic** and are reused unchanged:
+
+- **Frame transport is main-owned.** `src/main/ipc/emulator-frame-stream.ts:40`
+  runs the MJPEG socket in the main process and forwards raw JPEG bytes to the
+  renderer over `emulator:frameStreamFrame`. The renderer
+  (`src/renderer/src/components/emulator-pane/use-emulator-frame-stream.ts:74`)
+  just wraps each frame in a `Blob`/`<img>`. The renderer is a **frame
+  consumer**, decoupled from the source.
+- **Per-worktree "active emulator"** lives in
+  `src/main/emulator/emulator-session-registry.ts` (like the active browser
+  tab). Backend-agnostic.
+- **RPC** is declared in `src/main/runtime/rpc/methods/emulator.ts` and
+  implemented in `src/main/runtime/orca-runtime-emulator.ts`.
+- **CLI** is `src/cli/specs/emulator.ts` + `src/cli/handlers/emulator.ts`.
+- **Pane** is `src/renderer/src/components/emulator-pane/**` (~50 files).
+
+What is iOS-bound and needs an Android sibling:
+
+- Device management: `xcrun simctl` → `adb` / `emulator` / `avdmanager`.
+- Streaming helper: `serve-sim` (MJPEG/H.264 over HTTP+WS) → `scrcpy-server.jar`
+  (H.264 + control over adb-forwarded sockets).
+- Input: serve-sim normalized-coord WS → adb-backed Android input commands.
+- Availability gate: darwin-only → SDK-present on any OS.
+
+## Goals
+
+- Android emulation on **Windows, Linux, and macOS** (macOS users choose iOS or
+  Android in the same pane).
+- **Full AVD lifecycle**: discover installed AVDs via the SDK, boot/shutdown
+  them from Orca, and attach to already-running emulators + physical `adb`
+  devices.
+- **Live ~60fps pane** via scrcpy H.264 decoded in the renderer with WebCodecs.
+- Control parity: tap, swipe/gesture, type, hardware buttons (Back, Home,
+  Recents, Power, Volume), rotate.
+- Extra capabilities: accessibility tree (`uiautomator dump`), app
+  install/launch (`adb install` / `am start`), runtime permissions
+  (`pm grant/revoke/reset`), logcat capture.
+- A dedicated `skills/orca-emulator-android/SKILL.md`.
+
+## Non-goals (v1)
+
+- Camera/sensor injection (the Android emulator's virtual-scene path is a much
+  larger problem than serve-sim's iOS camera injection; defer).
+- Remote/SSH device control (matches the current iOS limitation; emulator
+  hardware is local).
+- Wear OS / Android TV / Automotive form factors.
+- Migrating the iOS backend to H.264 (the interface allows it later; not done
+  now).
+
+## Design
+
+### Extract an `EmulatorBackend` interface; make the bridge a router
+
+Today `EmulatorBridge` *is* the iOS implementation. Refactor it into a thin
+router over a backend interface so iOS and Android share the session registry,
+RPC/CLI shape, frame IPC, and tab system. This is the only change to existing
+iOS behavior, and it is a pure extraction (no semantic change).
+
+New module `src/main/emulator/backends/emulator-backend.ts`:
+
+```ts
+export type EmulatorBackendKind = 'ios' | 'android'
+export type EmulatorStreamCodec = 'mjpeg' | 'h264'
+
+export type EmulatorDevice = {
+  backend: EmulatorBackendKind
+  id: string            // opaque: simulator UDID, adb serial, or AVD name
+  name: string
+  state: 'shutdown' | 'booting' | 'booted'
+  kind?: string         // form factor / api level, display only
+  isAvailable: boolean
+}
+
+export type EmulatorBackendCapabilities = {
+  install: boolean
+  launch: boolean
+  permissions: boolean
+  accessibilityTree: boolean
+  logcat: boolean
+}
+
+export interface EmulatorBackend {
+  readonly kind: EmulatorBackendKind
+  readonly capabilities: EmulatorBackendCapabilities
+  isSupportedOnHost(): boolean
+  checkAvailability(): Promise<BackendAvailability>
+  listDevices(): Promise<EmulatorDevice[]>
+  bootDevice(id: string): Promise<EmulatorDevice>
+  startSession(id: string): Promise<EmulatorSessionInfo> // includes streamCodec
+  tap(id, x, y): Promise<void>
+  gesture(id, points): Promise<void>
+  type(id, text): Promise<void>
+  button(id, name): Promise<void>
+  rotate(id, orientation): Promise<void>
+  exec(id, command): Promise<unknown>
+  // capability-gated:
+  installApp?(id, path): Promise<void>
+  launchApp?(id, pkg, activity?): Promise<void>
+  setPermission?(id, op): Promise<void>
+  accessibilityTree?(id): Promise<unknown>
+  logcat?(id, opts): Promise<...>
+  stopSession(id): Promise<void>
+  kill(id): Promise<void>
+  shutdown(id): Promise<void>
+}
+```
+
+- `src/main/emulator/backends/ios-emulator-backend.ts` — the existing serve-sim
+  + simctl logic extracted from `EmulatorBridge`, implementing the interface
+  with `kind: 'ios'`, `streamCodec: 'mjpeg'`, and capabilities mapped to what
+  serve-sim already supports.
+- `src/main/emulator/backends/android-emulator-backend.ts` — new, orchestrates
+  the Android modules below with `kind: 'android'`, `streamCodec: 'h264'`.
+- `EmulatorBridge` keeps its public method names (so RPC/runtime callers don't
+  churn) but becomes a router: it holds the available backends, resolves which
+  backend owns a given device/session (via the session registry's recorded
+  `backend` tag, or by probing `listDevices()` for an unknown id), and
+  delegates. The session registry record gains a `backend: EmulatorBackendKind`
+  field; `EmulatorSessionInfo` gains `streamCodec`. The existing `deviceUdid`
+  field is retained as the opaque `id` to preserve wire-compat across the
+  renderer and CLI.
+
+### New Android modules — `src/main/emulator/android/`
+
+Each module is small and single-purpose with a co-located `.test.ts`, matching
+the existing `serve-sim-*` / `simctl-*` granularity (no file approaches the
+`max-lines` limit):
+
+- `android-sdk-discovery.ts` — resolve the SDK root and the `adb` / `emulator` /
+  `avdmanager` binaries from `ANDROID_HOME`, then `ANDROID_SDK_ROOT`, then per-OS
+  defaults: `%LOCALAPPDATA%\Android\Sdk` (Windows), `~/Library/Android/sdk`
+  (macOS), `~/Android/Sdk` (Linux). All paths via `path.join`.
+- `adb-devices.ts` — `adb devices -l`, resolve serial, `wait-for-device` +
+  `getprop sys.boot_completed` poll, and `wm size` for the device resolution.
+- `avd-manager.ts` — `emulator -list-avds`, boot an AVD via a detached
+  `emulator @<name>` spawn, shut down via `adb -s <serial> emu kill`.
+- `scrcpy-server-deploy.ts` — push the version-pinned `scrcpy-server.jar`, start
+  it via `app_process`, and set up the `adb forward` tunnel(s).
+- `scrcpy-stream-session.ts` — owns the server process, adb tunnel, and video
+  socket lifecycle.
+- `scrcpy-video-frame-parser.ts` — read the video socket, parse scrcpy frame headers
+  (PTS + length), and emit H.264 access units plus the codec config (SPS/PPS).
+- `scrcpy-control-protocol.ts` — encode scrcpy control messages (touch
+  down/move/up with pointer id + pressure, inject keycode, inject UTF-8 text,
+  scroll, set screen power, rotate, clipboard) for a future low-latency input path.
+- `android-input-mapping.ts` — convert normalized 0–1 ↔ device pixels using the
+  live frame size; map button names → Android keycodes (BACK=4, HOME=3,
+  APP_SWITCH=187, POWER=26, VOLUME_UP=24, VOLUME_DOWN=25).
+- `android-input-commands.ts` — current adb-backed tap/type/button/rotate/gesture
+  command construction.
+- `uiautomator-tree.ts` — `adb shell uiautomator dump` → parsed XML tree.
+- `android-app-control.ts` — `adb install <apk>`, `am start` package/activity.
+- `android-permissions.ts` — `pm grant` / `revoke` / `reset`.
+- `android-logcat.ts` — tail/filter `adb logcat` with bounded buffering.
+- `android-availability.ts` — SDK present? AVDs + connected devices list, with
+  clear, surfaced messages (mirroring the iOS availability message style).
+
+### Streaming & control data flow
+
+**Control currently uses `adb shell input` commands.** Coordinates stay
+normalized 0–1 at every public boundary (CLI, RPC, renderer); the Android backend
+maps them to device pixels before issuing adb-backed tap/gesture/button commands.
+The scrcpy control protocol encoders are present for a future low-latency input
+path, but video streaming does not require that path.
+
+**Video path (H.264 → renderer WebCodecs):**
+
+1. `android-emulator-backend.startSession()` deploys + starts scrcpy-server,
+   opens the video + control sockets, and returns `EmulatorSessionInfo` with
+   `streamCodec: 'h264'`.
+2. `scrcpy-video-stream.ts` reads access units and the SPS/PPS config and pushes
+   them over a **new IPC channel** `emulator:videoStream{Start,Config,Frame,Stop}`
+   (a sibling of the existing `emulator:frameStream*`), keyed by stream id.
+3. New renderer hook
+   `src/renderer/src/components/emulator-pane/use-emulator-video-stream.ts`
+   feeds the access units to a WebCodecs `VideoDecoder`, drawing decoded
+   `VideoFrame`s to a `<canvas>`.
+4. `src/renderer/src/components/emulator-pane/emulator-screen-stream-content.tsx`
+   branches on `session.streamCodec`: `mjpeg` keeps today's `<img>` path
+   untouched; `h264` uses the canvas path. No iOS behavior changes.
+
+## Coordinate & input mapping
+
+- Public API (CLI/RPC/pane gestures) stays normalized 0–1, top-left origin, as
+  the iOS path already mandates.
+- `android-input-mapping.ts` multiplies by the current device display size before
+  adb input commands are built. Rotation changes the effective frame size; the
+  mapper reads the current size each gesture rather than caching.
+- Hardware buttons: adb keyevents inject keycodes. Android adds
+  **Back** and **Recents** (no iOS equivalent); the button name → keycode map
+  and the renderer's hardware-button row gain Android variants.
+
+## RPC + CLI surface
+
+Extend `src/main/runtime/rpc/methods/emulator.ts`,
+`src/main/runtime/orca-runtime-emulator.ts`, `src/cli/specs/emulator.ts`, and
+`src/cli/handlers/emulator.ts`:
+
+- `orca emulator list` gains a **platform column** and shows iOS + Android
+  devices/AVDs together; device selection resolves the backend automatically
+  (by recorded session tag, else by which backend's `listDevices()` owns the id).
+- Existing verbs (`attach`, `tap`, `gesture`, `type`, `button`, `rotate`,
+  `exec`, `kill`, `shutdown`) route unchanged to the resolved backend.
+- New capability-gated verbs: `install`, `launch`, `permissions`, `ax`,
+  `logcat`. On a backend lacking the capability they fail with a clear
+  `emulator_unsupported` error rather than silently no-op.
+- Existing `--worktree` / `--device` targeting is unchanged.
+
+## Renderer pane
+
+- `src/renderer/src/components/emulator-pane/emulator-phone-hardware-buttons.tsx`
+  → Android variant (Back, Home, Recents, Power, Volume) selected by backend
+  kind.
+- Android device bezel/frame + Android entries (and a "boot AVD" affordance) in
+  the attach/list UI.
+- `MobileEmulatorAgentSetupGuide*` → Android prerequisites step (install Android
+  Studio / SDK, set `ANDROID_HOME`).
+- Codec-aware stream content (the canvas path above).
+- All UI follows `docs/STYLEGUIDE.md`: existing tokens from
+  `src/renderer/src/assets/main.css` and shadcn primitives in
+  `src/renderer/src/components/ui/`; no new color/size/shadow values.
+- Shortcut labels and any new accelerators use the platform checks required by
+  `AGENTS.md` (`CmdOrCtrl`, `⌘`/`Ctrl+`).
+
+## Packaging & dependencies
+
+- Bundle the single, version-pinned `scrcpy-server.jar` (~80 KB) as an app
+  resource; wire it into `config/electron-builder.config.cjs` and
+  `config/packaged-runtime-node-modules.cjs`. Pin the scrcpy version — the
+  server protocol is coupled to the jar.
+- Do **not** bundle `adb` / `emulator` / `avdmanager` (large; Android Studio
+  installs them). Discover them at runtime and surface a clear setup message if
+  the SDK is absent.
+- No new runtime npm dependency is required for decode (WebCodecs is built into
+  Electron's Chromium). The wasm-decoder fallback (see Risks) would add a dep
+  only if the WebCodecs spike fails.
+
+## Skill
+
+New `skills/orca-emulator-android/SKILL.md`, mirroring
+`skills/orca-emulator/SKILL.md`:
+
+- Prerequisites: Android Studio / SDK installed, `ANDROID_HOME` (or
+  `ANDROID_SDK_ROOT`) set, at least one AVD or a connected device.
+- The `orca emulator ...` command table (shared CLI; Android examples).
+- Gotchas: Orca handles pixel ↔ normalized conversion (agents always pass 0–1);
+  adb device/serial targeting; no camera injection in v1; scrcpy version
+  coupling.
+- Cross-reference from the iOS skill's "When NOT to use" (which already
+  anticipates an Android backend under the same namespace).
+- Register it the same way `orca-emulator` is registered.
+
+## Availability & platform gating
+
+`src/main/emulator/emulator-availability.ts` becomes an aggregator that asks
+each backend `isSupportedOnHost()` + `checkAvailability()`:
+
+- iOS backend: supported only on `darwin` (unchanged behavior/messages).
+- Android backend: supported on any OS where the SDK is discoverable.
+- The combined result drives the pane's availability UI; Windows/Linux report an
+  available mobile backend for the first time.
+
+## Edge cases
+
+- adb device in `offline` / `unauthorized` state → clear surfaced error, not a
+  hang.
+- AVD boot timeout (cold boot can take minutes) → bounded wait with a
+  cancel/error path; pane shows "booting".
+- SDK present but no AVDs and no devices → availability message points to "create
+  an AVD in Android Studio".
+- Device rotates while a gesture is mid-flight → mapper re-reads frame size per
+  event; no cached dimensions.
+- Multiple Android devices in one worktree → same "one active per worktree"
+  model as iOS; explicit `--device <serial>` for the rest.
+- WebCodecs decoder error / key-frame loss → request a new keyframe from scrcpy
+  and surface a transient "reconnecting" state (parity with the MJPEG reconnect
+  in `mjpeg-frame-stream.ts`).
+- Windows path handling for the SDK and the pushed jar uses `path.join` only;
+  never assume `/` or `\`.
+- App quit / pane close cleans up scrcpy-server, the adb tunnel, and (for managed
+  AVDs) the emulator, mirroring `EmulatorBridge.onAppQuit()` /
+  `destroyAllSessions()`.
+
+## Test plan
+
+Unit tests (co-located, node Vitest, matching the module's existing test
+density):
+
+- `android-sdk-discovery` — env precedence + per-OS default paths (mock env/fs;
+  assert Windows/macOS/Linux branches).
+- `adb-devices` — parse `adb devices -l` (booted, offline, unauthorized,
+  physical), boot-complete polling.
+- `avd-manager` — parse `emulator -list-avds`, boot command construction.
+- `scrcpy-control-channel` — exact byte encoding of touch/key/text/scroll
+  messages.
+- `android-input-mapping` — normalized↔pixel round-trips, rotation, keycode map.
+- `uiautomator-tree` — XML → tree parsing, including malformed input.
+- `android-availability` + `emulator-availability` aggregation — iOS-only,
+  Android-only, both, neither.
+- backend router resolution in `emulator-bridge` — id → backend, unknown id,
+  cross-backend isolation.
+
+Integration tests mock `adb` / `emulator` and the scrcpy sockets the same way
+the iOS tests mock serve-sim (`serve-sim-*.test.ts`, `emulator-bridge.test.ts`).
+
+Electron validation (manual, on a machine with the Android SDK):
+
+- Boot an AVD from Orca; confirm the live pane streams and is responsive.
+- tap / swipe / type / Back / Home / Recents / rotate.
+- `ax`, `install` + `launch`, `permissions grant`, `logcat`.
+- Cross-platform smoke on Windows (primary driver) and macOS (iOS + Android
+  coexistence).
+
+## Risks / verify-first
+
+- **Electron H.264 WebCodecs decode** — verify in a step-0 spike that an Electron
+  renderer `VideoDecoder` decodes scrcpy's H.264. Electron ships proprietary
+  codec decode, so this is expected to pass. Fallback if not: a wasm H.264
+  decoder (Broadway / tinyh264) or dropping to a main-process H.264→JPEG
+  transcode — **neither changes the backend interface**, since the session
+  advertises its codec.
+- **scrcpy-server protocol is version-coupled** to the bundled jar (same class of
+  risk as serve-sim's private SimulatorKit APIs). Pin the version; record it next
+  to the bundled jar.
+- **adb/emulator environment variance** — offline/unauthorized devices, cold-boot
+  timeouts, missing SDK. All handled via explicit, surfaced errors.
+
+## Rollout
+
+1. Step-0 spike: confirm WebCodecs H.264 decode in the Electron renderer.
+2. Extract the `EmulatorBackend` interface + `IosEmulatorBackend` (pure
+   refactor); keep all iOS tests green.
+3. Android device management (`android-sdk-discovery`, `adb-devices`,
+   `avd-manager`, `android-availability`) + availability aggregation; surface
+   Android devices in `orca emulator list`.
+4. scrcpy streaming (`scrcpy-server-deploy`, `scrcpy-video-stream`) + the video
+   IPC channel + the renderer WebCodecs canvas path; live pane renders.
+5. scrcpy control (`scrcpy-control-channel`, `android-input-mapping`) +
+   tap/gesture/type/button/rotate end-to-end.
+6. Extra capabilities: `ax`, `install`/`launch`, `permissions`, `logcat`.
+7. Renderer polish: Android hardware buttons, bezel, setup guide.
+8. Packaging (`scrcpy-server.jar` resource) + the `orca-emulator-android` skill.
+9. Tests at each step; typecheck + lint; Electron validation on Windows + macOS.
+
+## Open decisions
+
+- Whether `orca emulator install`/`launch`/`logcat` should also be exposed for
+  iOS later (iOS install is `xcrun simctl install`); v1 leaves them
+  Android-only via capability flags.
+- Whether to expose an explicit `orca emulator boot <avd>` verb vs. folding boot
+  into `attach`; initial version folds boot into `attach` (parity with iOS,
+  which boots on attach) and adds a `--no-boot` opt-out.

+# GitHub Tasks Close Reason Parity
+
+## Problem
+
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1025) renders `GHStatusCell` with only `Open` and `Closed`.
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1064) sends `{ state: 'closed' }`, so the list path cannot choose GitHub close reasons.
+- [TaskPage.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/TaskPage.tsx:1137) styles closed issues with rose/destructive color, while GitHub treats closing as a neutral/purple completion action rather than a delete/error action.
+- [GitHubItemDialog.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/GitHubItemDialog.tsx:4960) has a separate issue-detail status popover; it must expose the same close reasons so opening an issue from Tasks does not fall back to the old Open/Closed-only UI.
+- [GitHubIssueCommentComposer.tsx](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/renderer/src/components/github/GitHubIssueCommentComposer.tsx:188) already supports close reasons in the detail composer, but the Tasks list does not.
+
+## Goal
+
+Bring the GitHub Tasks list status menu closer to GitHub:
+
+1. Closed issue UI must stop using destructive red styling.
+2. Open issues must expose close-as-completed, close-as-not-planned, and close-as-duplicate from the status menu.
+3. Duplicate closes must require a target issue number and pass it as `duplicateOf`.
+4. Reopening still works from the same status menu.
+5. GitHub issue detail metadata must use the same close-reason and duplicate-picker behavior as the Tasks row.
+
+## Non-goals
+
+- No provider-generic changes for GitLab, Linear, or Jira.
+- No network-backed GitHub issue search picker in this pass; the duplicate picker uses the loaded Tasks cache plus an exact issue-number fallback.
+- No schema changes or cache migration.
+- No change to PR status behavior.
+- No automatic cross-window broadcast beyond the existing cache/list refresh mechanics; this pass updates the current renderer optimistically and relies on normal refetch in other windows.
+
+## Design
+
+1. Add a small TaskPage GitHub status menu model in a named module, including option metadata, duplicate-target validation, and payload construction for close reasons.
+2. Update `GHStatusCell` so `handleStateChange` accepts close options, optimistically patches only the issue `state`, and sends `stateReason` plus optional `duplicateOf`.
+3. Route issue-state mutations by issue identity:
+   - If the row URL parses to `owner/repo`, use `github.project.updateIssueBySlug` / runtime `github.project.updateIssueBySlug`. This avoids closing the wrong repository for GitHub project/custom-source rows whose issue repo can differ from the caller repo.
+   - Otherwise keep the existing `github.updateIssue` path with `repoPath`/`repoId`/`sourceContext`.
+4. Render the status popover with `Open`, `Close as completed`, `Close as not planned`, and `Close as duplicate` in both the Tasks row and issue-detail metadata sidebar. The duplicate row advances to a second-step picker with a back button, search field, loaded issue candidates, and an exact-number fallback.
+5. Replace rose closed-state classes with token-based primary/ring color-mix classes so the closed pill is completion-like, not destructive. Keep the open-state green treatment for parity with the existing Tasks page unless a broader status-color pass changes it.
+6. Keep the payload serializable for IPC/runtime/SSH: `{ state, stateReason, duplicateOf }` only contains strings and numbers.
+
+## API Notes
+
+- The local path in [issues.ts](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/main/github/issues.ts:231) already closes issues with `gh issue close`. Preserve that model and pass:
+  - `--reason completed` for `stateReason: 'completed'`
+  - `--reason "not planned"` for `stateReason: 'not_planned'`
+  - `--duplicate-of <number>` for `stateReason: 'duplicate'` with `duplicateOf`
+- The slug path in [mutations.ts](/Users/jinwoohong/orca/workspaces/orca/tasks-page-parity/src/main/github/project-view/mutations.ts:160) must not implement duplicates by PATCHing `duplicate_of` on `repos/{owner}/{repo}/issues/{n}`. `gh issue close --duplicate-of` is the supported CLI surface already used by the path-based mutation, so slug-addressed state changes should use `gh issue close/reopen --repo owner/repo` for state and reserve REST PATCH for title/body.
+- When `stateReason: 'duplicate'` is sent without a valid `duplicateOf`, reject it before dispatch. Do not silently downgrade to plain closed or `--reason duplicate`, because GitHub's duplicate UX expects the target issue to be recorded.
+- Keep `state_reason` REST PATCH only for non-duplicate close reasons if the implementation deliberately stays on REST for completed/not-planned. The simpler consistency target is to route all slug-addressed state changes through `gh issue close/reopen`.
+
+## Data Flow
+
+- User opens a GitHub issue status pill.
+- Completed/not-planned click -> `handleStateChange('closed', { stateReason })`.
+- Duplicate click -> second-step picker -> select a loaded issue or exact target number -> `handleStateChange('closed', { stateReason: 'duplicate', duplicateOf })`.
+- Cell optimistically patches local state and store row state.
+- Mutation goes through local IPC or runtime RPC with the same repo/source context.
+- Failure reverts the local/store state and shows the existing error toast.
+- Success records the existing `github-tasks` feature interaction and should invalidate or refresh the relevant work-items cache entry if the current filter can hide the row after the state changes (for example, an `is:open` filter). Without that, a closed row can remain visible until a later refetch.
+
+## Edge Cases
+
+- Duplicate target is blank, zero, negative, decimal, or the same issue number: keep the picker open and show inline validation after Enter.
+- Duplicate target can be a different repository's issue only when the implementation accepts a URL; this pass takes a loaded same-repository issue or number, so validation and copy should describe it as an issue in the same repository.
+- The row refreshes while the menu is open: reconcile the optimistic draft before paint as the current status cell already does.
+- Rapid repeated choices: retain the existing request id guard so stale responses cannot revert a newer choice.
+- SSH/runtime target: payload must remain serializable and use the existing runtime method.
+- Multi-window consistency: do not assume another window's in-memory `workItemsCache` observes the optimistic patch. Ensure the mutation path updates GitHub authoritatively and that normal cache invalidation/refetch behavior eventually corrects other windows.
+- Project/custom-source rows: prefer the parsed issue URL slug over the selected local repo when available, because a GitHub Project can contain issues from repositories other than the current worktree.
+- PR rows and rows without a repo continue to render a non-editable status pill.
+- Rows without a parsed slug and without a local repo/source context should stay non-editable; do not attempt a mutation from only an issue number.
+
+## Test Plan
+
+- Unit: menu model builds `{ state: 'closed', stateReason: 'completed' }`, `{ state: 'closed', stateReason: 'not_planned' }`, and duplicate payloads only for valid duplicate targets.
+- Unit: duplicate validation rejects missing/self/non-positive/non-integer targets.
+- Existing unit: optimistic status draft reconciliation remains unchanged.
+- Main unit: `updateIssue` emits `gh issue close --reason completed`, `gh issue close --reason "not planned"`, `gh issue close --duplicate-of <n>`, and `gh issue reopen`.
+- Main unit: `updateIssueBySlug` uses `gh issue close/reopen --repo owner/repo` for state changes, rejects duplicate without `duplicateOf`, and does not send unsupported `duplicate_of` REST fields.
+- Renderer unit: `GHStatusCell` uses slug-addressed mutation when `item.url` contains an owner/repo and falls back to `github.updateIssue` only when slug parsing is unavailable.
+- Store/cache unit: successful close from an open-filtered Tasks list invalidates or refreshes the affected work-items cache so hidden-by-filter rows do not linger indefinitely.
+- Electron validation: Tasks GitHub issue row status menu shows the new close options and closed issue pill is not red.
+- Electron validation: duplicate close picker appears after the duplicate action and supports issue search/exact-number fallback. Do not submit a real close mutation against user data.
+- Electron validation: GitHub issue detail status sidebar shows the same close options and duplicate picker as the list row.
+- Electron/runtime smoke: same menu opens and validation works when the active runtime target is an SSH/environment source; avoid a real close mutation unless using disposable test data.
+
+## UI Quality Bar
+
+- Popover should feel like an action menu, not an error/destructive confirmation.
+- Closed issue pill must be visually distinct from open but not red/destructive.
+- Duplicate picker must fit in the popover at desktop and narrow widths without clipping.
+- Hover, focus, disabled, and inline validation states use existing shadcn primitives/tokens.
+
+## Review Screenshots
+
+1. GitHub Tasks issue row with status popover open showing all close reasons.
+2. Duplicate close second-step picker with search and issue candidates.
+3. Closed issue row/pill showing non-red completion styling.
+4. GitHub issue detail sidebar status popover showing all close reasons.
+5. GitHub issue detail duplicate close second-step picker.
+6. Adjacent smoke: GitHub Tasks header/search area still renders normally.
+
+## Rollout
+
+1. Add status menu model and tests.
+2. Update `GHStatusCell` UI and mutation payload.
+3. Run focused tests, typecheck, and lint.
+4. Run UI quality review.
+5. Validate in Electron and capture screenshots.
+
+## Lightweight Eng Review
+
+- Scope: kept to the GitHub Tasks status cell plus a small model module; no provider-wide or network-backed search-picker work.
+- Architecture/data flow: preserves current renderer -> IPC/runtime mutation boundaries, but must route rows with parseable GitHub slugs through `updateIssueBySlug` so project/custom-source issues mutate the issue's own repository rather than the selected worktree repo.
+- API feasibility: path-based mutations already use the supported `gh issue close --duplicate-of` CLI path; slug-addressed mutations need the same CLI close/reopen treatment instead of REST `duplicate_of`.
+- Failure modes covered:
+  - Invalid duplicate targets stay local and do not mutate.
+  - Failed mutations revert optimistic state using the existing request id guard.
+  - Runtime/SSH remains on the existing serializable RPC method.
+  - Unsupported duplicate API shape is avoided by keeping duplicate close on `gh issue close --duplicate-of`.
+  - Rows filtered by open/closed status do not rely solely on optimistic patching; the relevant work-items cache must be invalidated/refetched after success.
+- Test coverage required:
+  - Unit tests for close update payloads and duplicate validation.
+  - Main-process tests for both `updateIssue` and `updateIssueBySlug` close/reopen command generation.
+  - Renderer routing tests for slug-addressed versus repo-path-addressed issue rows.
+  - Cache invalidation/refetch coverage for status-filtered Tasks lists.
+  - Existing status draft tests for optimistic reconciliation.
+  - Electron screenshots for menu, duplicate validation, closed styling, and adjacent header smoke.
+- Performance/blast radius: no material concern; one extra tiny model import and no new polling/IPC.
+- UI quality bar: compact GitHub-like action menu, token-based non-destructive closed styling, no clipping or overlap.
+- Required review screenshots:
+  1. Status popover with close reasons.
+  2. Duplicate second-step picker with search and issue candidates.
+  3. Non-red closed status pill.
+  4. Tasks header/search smoke.
+- Residual risks:
+  - Duplicate target search is limited to loaded Tasks cache candidates, with exact-number fallback for unloaded same-repository issues.
+  - Other open Orca windows may show stale status until their normal GitHub Tasks data refresh runs.

+# Native Chat Codex TUI Parity
+
+This note maps Codex TUI behavior to Orca native chat on branch
+`inspect/pr-5824-native-chat`. It is intentionally concrete: the current Orca
+surface is a PTY harness around the running TUI, while real native parity should
+move selected paths to Codex app-server protocol v2.
+
+## Source Map
+
+- Codex TUI composer: `/Users/jinwoohong/stably/codex/codex-rs/tui/src/bottom_pane/chat_composer.rs`
+- Slash command parsing and popup:
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/bottom_pane/prompt_args.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/bottom_pane/slash_commands.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/slash_command.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/chatwidget/slash_dispatch.rs`
+- Skills and mentions:
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/bottom_pane/skill_popup.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/tui/src/skills_helpers.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/core-skills/src/loader.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/core-skills/src/root_loader.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/core-skills/src/injection.rs`
+- Structured input and native protocol:
+  `/Users/jinwoohong/stably/codex/codex-rs/protocol/src/user_input.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/app-server-protocol/src/protocol/v2/turn.rs`,
+  `/Users/jinwoohong/stably/codex/codex-rs/app-server-protocol/src/protocol/common.rs`
+
+## Current Orca Architecture
+
+Orca native chat currently sends through the hosted terminal PTY. The composer
+builds paste bytes, writes them through `sendRuntimePtyInput`, then sends a
+delayed Enter. This preserves local and SSH behavior because it uses the same
+runtime path as terminal typing.
+
+That architecture is useful for incremental adoption, but it means native chat
+does not own Codex state. It cannot directly set model, reasoning, permissions,
+skills, or session lifecycle. It can only type commands into the TUI and observe
+agent hooks/transcripts after the fact.
+
+## Slash Commands
+
+Codex behavior:
+
+- The parser accepts a first-line command of `/name <rest>`.
+- The slash popup uses Codex's `SlashCommand` enum order as presentation order.
+- Enter on a selected popup row dispatches the command. Tab completes it into
+  the draft.
+- Some commands accept inline args: `review`, `rename`, `plan`, `goal`, `ide`,
+  `keymap`, `mcp`, `raw`, `usage`, `pets`, `side`, `resume`, and
+  `sandbox-add-read-dir`.
+- Commands are control actions, not ordinary user chat turns. For example
+  `/clear` sends `AppEvent::ClearUi`; `/compact` starts compaction; `/model`
+  opens the model picker; `/skills` opens skill management.
+
+Current Orca behavior:
+
+- Slash commands are still typed into the TUI over PTY.
+- Native optimistic chat bubbles are suppressed for slash drafts so `/clear`
+  does not render as a fake queued user message.
+- The Codex slash catalog now mirrors the visible TUI command list much more
+  closely, but it is still a copied catalog, not a live TUI query.
+
+Recommended route:
+
+- Short term: keep PTY dispatch for slash commands, but treat them as command
+  submissions. No optimistic chat bubbles. Enter dispatches; Tab completes.
+- Medium term: route commands with app-server equivalents directly. Examples:
+  `thread/compact/start`, `thread/list`, `thread/archive`, `thread/delete`,
+  `model/list`, permissions/config reads and writes, `skills/list`.
+- Long term: stop maintaining a renderer-side Codex command catalog. Either ask
+  Codex for the command inventory or host the Codex composer state machine.
+
+## Skills And `$`
+
+Codex behavior:
+
+- `$` opens the skill popup. Rows show display name, description, category tags,
+  selection state, filtering, sorting, and scrolling.
+- Codex discovers skills from repo, user, system, admin, and plugin roots. Repo
+  scope sorts before user/system/admin. Exact duplicate paths are deduped.
+- Skill selection is structured. `UserInput` has `Skill { name, path }`, and
+  app-server protocol v2 mirrors it. Text `$skill` mentions are only the
+  fallback path and must be unambiguous.
+- Skill injection reads the selected `SKILL.md` by path, records telemetry, and
+  avoids double-injecting already provided host skill prompts.
+
+Current Orca behavior:
+
+- Native chat discovers skills through Orca's skills IPC with the active
+  terminal tab's cwd. This is important for worktree symlinks like
+  `.agents/skills`.
+- `$` autocomplete inserts plain `$skillName` text. That can work through the
+  TUI's text fallback, but it is not equivalent to structured
+  `UserInput::Skill { name, path }`.
+
+Recommended route:
+
+- PTY mode: keep `$skill` text insertion, but preserve Codex-like filtering,
+  scrolling, dedupe, and active-cwd discovery.
+- Native mode: retain the selected skill's path and submit
+  `UserInput::Skill { name, path }` through app-server `turn` input. This avoids
+  ambiguity when multiple skills share a name and lets Codex inject the exact
+  file the user selected.
+
+## Files, Mentions, And Images
+
+Codex behavior:
+
+- User input supports `Text` with text elements, `Image`, `LocalImage`,
+  `Skill`, and `Mention`.
+- The TUI has file search/mentions and image placeholders. Large pastes become
+  placeholders so text element ranges stay aligned.
+- Remote image rows are first-class composer attachments and can be removed with
+  keyboard navigation.
+
+Current Orca behavior:
+
+- File attach inserts a path/reference into the draft and relies on the TUI to
+  interpret it.
+- Image paste saves a temp file, then inserts the agent-specific reference.
+- Local attachments are blocked for remote sessions because the local path may
+  not exist on the SSH target.
+
+Recommended route:
+
+- PTY mode: keep conservative path insertion and remote-session blocking.
+- Native mode: send structured `LocalImage` or `Image` input through Codex
+  protocol and use remote runtime file transfer semantics for SSH.
+
+## Model, Reasoning, Permissions
+
+Codex behavior:
+
+- `/model`, `/permissions`, `/keymap`, `/vim`, `/experimental`, and related
+  commands are stateful TUI/app-server surfaces.
+- App-server v2 already exposes model listing, config requirements, approval
+  policies, permission profiles, and reasoning effort fields.
+
+Current Orca behavior:
+
+- Native chat does not know or set Codex model/reasoning directly. Typing
+  `/model` opens Codex's TUI picker.
+- Earlier UI controls for model/thinking were removed because they were not
+  wired to real Codex state.
+
+Recommended route:
+
+- Do not re-add model or reasoning dropdowns until they read from and write to
+  Codex app-server state.
+- In PTY mode, expose `/model` as a command shortcut only.
+
+## Approvals, Elicitations, And Tool UI
+
+Codex behavior:
+
+- Approval overlays cover exec approval, permission approval, file change
+  approval, network approval, MCP elicitation, and request-user-input forms.
+- App-server notifications include thread status, waiting-on-approval/user-input
+  flags, item start/completion, diff/plan updates, and skill changes.
+
+Current Orca behavior:
+
+- Native chat has interactive cards sourced from Orca's existing agent status
+  hooks. This is good for common question/approval flows, but it is not the full
+  Codex approval overlay model.
+
+Recommended route:
+
+- Keep PTY fallback for anything not represented in Orca hooks.
+- For Codex-native mode, subscribe to app-server notifications and render
+  approvals/tool calls from protocol events rather than scraping terminal text.
+
+## Session And History
+
+Codex behavior:
+
+- `/new`, `/resume`, `/fork`, `/archive`, `/delete`, `/compact`, and `/clear`
+  are session lifecycle commands.
+- The composer has local and persistent history; Up/Down recall, Ctrl+R reverse
+  search, Esc edit/interrupt behavior, Ctrl+J newline, Ctrl+T transcript, and
+  Ctrl+C quit/interrupt behavior.
+
+Current Orca behavior:
+
+- Native chat has small in-memory draft history and Enter/Shift+Enter.
+- Session commands are typed into the hosted TUI.
+
+Recommended route:
+
+- Short term: keep TUI command dispatch and avoid fake optimistic bubbles for
+  lifecycle commands.
+- Native mode: use app-server thread APIs for lifecycle and expose real thread
+  transitions in the Orca UI.
+
+## Priority
+
+1. Fix PTY-command correctness: Enter dispatches slash commands, Tab completes,
+   slash commands never render as queued chat turns, interrupt clears working UI.
+2. Make `$` skill popup match Codex basics: active cwd, dedupe, scrolling,
+   filtering, source labels, and no product-specific hardcoding.
+3. Keep fake model/thinking controls out until backed by Codex app-server state.
+4. Add an app-server integration spike for Codex native mode: `skills/list`,
+   structured `UserInput::Skill`, model list/settings, and thread lifecycle.
+5. Move approvals/tool rendering from hook approximations to protocol events.
+
+## Test Targets
+
+- `/clear` from native slash popup dispatches immediately and produces no
+  pending user bubble.
+- `/compact`, `/model`, `/skills`, `/resume`, `/diff`, `/status`, and unknown
+  slash commands behave like the hosted TUI.
+- `$ref-oss` appears exactly once when the worktree has `.agents/skills` as a
+  symlink.
+- Down-arrow in `$` suggestions scrolls the popup window.
+- Interrupt during work returns the composer from Stop to Send after the agent
+  status settles.
+- SSH sessions never insert local-only attachment paths as if they were remote
+  files.

+# Design: Manual network address entry for Orca desktop mobile pairing
+
+**Date:** 2026-06-27
+**Scope:** Desktop renderer (Settings → Mobile → Network Interface section)
+**Status:** Draft, awaiting user review
+
+## Problem
+
+`src/renderer/src/components/settings/MobileNetworkInterfaceSection.tsx` lets the user pick the network address that gets baked into the mobile-pairing QR code. Today the only options come from `networkInterfaces`, which is the list returned by the main process enumerating OS network interfaces (`en0`, `tailscale0`, etc.). If a user wants a tailnet address that the OS hasn't surfaced yet — a Tailscale MagicDNS hostname, a ZeroTier-assigned address not yet visible to the OS, or a manual LAN IP — they have no way to type one in. The QR ends up pointing at an interface the phone cannot actually reach.
+
+## Decision summary
+
+Replace the inner `Select` of `MobileNetworkInterfaceSection` with a `Popover + Command` ("combobox") pattern modeled on the existing `AgentCombobox`. The popover contains a single `CommandInput` that filters the auto-discovered interfaces above and renders a special "Use …" entry at the bottom of the list whenever the input is a valid IPv4 address or Tailscale MagicDNS hostname. Picking that entry selects a custom address; the trigger shows `<address> (custom)`. Custom addresses are session-scoped (cleared when the settings pane closes).
+
+## Constraints (from `CONTRIBUTING.md` + `AGENTS.md`)
+
+- Cross-platform: code paths must not assume a single platform; the manual entry path itself is platform-neutral.
+- No `helpers`/`utils`/`misc` file names; use concrete names.
+- No `eslint-disable max-lines`; split files instead.
+- Prefer `.ts` over `.d.ts`.
+- UI work follows `docs/STYLEGUIDE.md` and uses shadcn primitives from `src/renderer/src/components/ui/`.
+- The renderer ↔ shared boundary is `src/shared/`; pure logic that may be reused outside the renderer goes there.
+- Comments explain *why*, briefly.
+
+## Files
+
+| Path | Change |
+| --- | --- |
+| `src/shared/network/manual-address.ts` | **New.** Pure `parseManualNetworkAddress(input)` returning a discriminated union. |
+| `src/shared/network/manual-address.test.ts` | **New.** Vitest cases for IPv4 and MagicDNS hostname validation. |
+| `src/renderer/src/components/settings/mobile-network-interface-selection.ts` | Replace `mergeForSelect` with `buildComboboxEntries(interfaces, customAddress)` returning the entry list the UI maps over. |
+| `src/renderer/src/components/settings/mobile-network-interface-selection.test.ts` | Replace `mergeForSelect` tests with `buildComboboxEntries` tests. |
+| `src/renderer/src/components/settings/MobileNetworkInterfaceSection.tsx` | Swap `Select` for `Popover + Command`; add `open`/`query`/`customAddress` state. |
+| `src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx` | **New.** Render tests via `@testing-library/react`. |
+
+No changes to: `mobile/app/pair-scan.tsx`, `MobilePairingQrSection.tsx`, `use-mobile-install-qr.ts`, or any main-process code. The QR generation pipeline already consumes `selectedAddress: string`, which is all the new flow produces.
+
+## Module 1: `parseManualNetworkAddress`
+
+```ts
+// src/shared/network/manual-address.ts
+export type ParseManualAddressResult =
+  | { ok: true; address: string }
+  | { ok: false; error: string }
+
+export function parseManualNetworkAddress(input: string): ParseManualAddressResult
+```
+
+**Rules** (in order):
+
+1. `input.trim()` must be non-empty. Otherwise `{ ok: false, error: 'Enter an IPv4 address or Tailscale MagicDNS hostname' }`.
+2. Reject any input containing whitespace anywhere; reject any input longer than 253 chars (DNS hostname cap).
+3. Accept if it matches the IPv4 grammar (four dotted octets, each 0–255). No leading zeros except for `0` itself.
+4. Accept if it matches the Tailscale MagicDNS hostname grammar:
+   - Regex (case-insensitive): `/^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?(\.[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?)*\.ts\.net$/`
+5. Otherwise return the same error as (1).
+
+Pure function, no React, no I/O. Unit-testable in isolation.
+
+## Module 2: `buildComboboxEntries`
+
+```ts
+// src/renderer/src/components/settings/mobile-network-interface-selection.ts
+export type MobileNetworkInterface = { name: string; address: string }
+
+export type ComboboxEntry =
+  | { kind: 'interface'; iface: MobileNetworkInterface }
+  | { kind: 'use-query'; address: string }   // only emitted when current query is valid
+
+export function buildComboboxEntries(
+  interfaces: readonly MobileNetworkInterface[],
+  query: string
+): readonly ComboboxEntry[]
+```
+
+**Behavior:**
+
+- Trim `query`; if empty, return only `kind: 'interface'` entries from `interfaces` (no `use-query`).
+- If `query` is non-empty, behavior branches on `parseManualNetworkAddress(query)`:
+  - **Valid query:** skip substring filtering and keep every interface visible (so the user can pivot to an existing interface mid-typing). Emit each as `kind: 'interface'`.
+  - **Invalid query:** filter `interfaces` by case-insensitive substring match on `iface.address` OR `iface.name`. Emit each as `kind: 'interface'`. If the filter yields zero matches, fall back to the full `interfaces` list (so the user always sees the available options, never an empty list mid-typing).
+- After the interface entries, if the query parsed as valid AND no emitted interface has an `address` exactly equal to `parsed.address`, append `{ kind: 'use-query', address: parsed.address }`. (Suppression happens regardless of whether filtering ran, because valid queries skip filtering entirely — the check is against the visible interface list, which for valid queries is the full list.)
+- Order: interface entries first (stable, in input order — either filtered or the full list per the branch above), then the optional `use-query`.
+- The `selectRefreshedNetworkAddress` function is **kept** unchanged — it's still the rule that decides the *initial* `selectedAddress` when no manual entry exists. The UI calls it on mount and on Refresh; afterwards, the combobox owns the selection.
+
+## Module 3: `MobileNetworkInterfaceSection` UI
+
+Outer JSX (header text, description, Generate QR button, Refresh button, Tailnet accordion) is untouched. Only the inner selection control is replaced.
+
+**State:**
+
+```ts
+const [open, setOpen] = useState(false)
+const [query, setQuery] = useState('')
+const [customAddress, setCustomAddress] = useState<string | null>(null)
+```
+
+`customAddress` is the last value the user confirmed via the `use-query` entry. It is the "session-scoped" custom selection that the trigger displays with the `(custom)` label. It is reset when the settings pane unmounts (React unmount handles this automatically; no global store involved).
+
+**Trigger:** A `Button` styled like the existing `SelectTrigger` (`min-w-[220px]`, `size="sm"`). Label uses the same `formatInterfaceLabel` helper:
+
+```ts
+function formatInterfaceLabel(iface: { name: string; address: string }): string {
+  return `${iface.address} (${iface.name})`
+}
+```
+
+For the custom selection the rendered iface is `{ name: 'custom', address: customAddress }`, so the trigger shows `100.64.1.20 (custom)`.
+
+**Popover body:** `Command` containing:
+
+- `CommandInput` with placeholder `Search or type an address…` and `value={query}` / `onValueChange={setQuery}`.
+- `CommandList` containing:
+  - `CommandEmpty` shown only when no interfaces match AND `parseManualNetworkAddress(query)` is invalid (i.e., truly nothing to pick).
+  - One `CommandItem` per `kind: 'interface'` entry from `buildComboboxEntries(networkInterfaces, query)`. `onSelect` calls `onSelectedAddressChange(iface.address)`, `setCustomAddress(null)`, `setQuery('')`, `setOpen(false)`.
+  - Optional visual separator (e.g., `CommandSeparator`) before the `use-query` entry.
+  - One `CommandItem` for `kind: 'use-query'` (only present when query is valid). Label: `Use "<query>"`. `onSelect` calls `onSelectedAddressChange(address)`, `setCustomAddress(address)`, `setQuery('')`, `setOpen(false)`.
+
+**Controlled cmdk selection:** Copy the controlled-`commandValue` pattern from `src/renderer/src/components/agent/AgentCombobox.tsx` (imports `createAgentComboboxCommandState`, `resolveAgentComboboxCommandState`, `updateAgentComboboxCommandValue` from `@/components/agent/agent-combobox-command-state`, plus the `Command`, `CommandEmpty`, `CommandInput`, `CommandItem`, `CommandList` primitives from `@/components/ui/command`) so that hovering the footer doesn't leave a stale highlight on a list item. The exact state shape will be minimal — only one list, no footer-group complexity — so the borrowed helpers are sufficient. No new helpers are introduced in this design.
+
+**Validation feedback:**
+
+- When `query` is non-empty and invalid, render a one-line `text-xs text-statusRed` message directly below the trigger: `"Enter an IPv4 address or Tailscale MagicDNS hostname"`. Use the existing `statusRed` token from the theme to stay style-guide compliant.
+- The `use-query` entry only appears when valid; no need to disable it.
+
+**Refresh button:** Unchanged. Calls `onRefreshNetworkInterfaces`. The combobox re-renders with the new `networkInterfaces`; `query` and `customAddress` are preserved (user might be mid-typing).
+
+**Generate QR button:** Unchanged. Disabled when `!selectedAddress`. No new branches.
+
+## Data flow
+
+```
+networkInterfaces (prop, refreshed by parent)
+        │
+        ▼
+buildComboboxEntries(networkInterfaces, query)
+        │
+        ▼
+CommandList rows
+        │
+        ▼ onSelect
+onSelectedAddressChange(string)  ─► parent re-renders MobilePairingQrSection
+                                  ─► QR is regenerated with new endpoint
+```
+
+The parent of `MobileNetworkInterfaceSection` (whichever Settings tab owns it) already maintains `selectedAddress` and re-passes it down. This design does not change that contract.
+
+## Edge cases
+
+1. **Duplicate manual entry vs. existing interface** — `buildComboboxEntries` suppresses the `use-query` entry whenever the parsed query exactly equals an emitted interface's `address`. For valid queries the visible list is the full interface list (no substring filter runs), so the suppression check is against every interface, not just filtered ones. The user lands on the existing interface row instead of a duplicate.
+2. **OS discovers the manual address later** — If `customAddress === '100.64.1.20'` and a refresh surfaces `100.64.1.20 (tailscale0)`, both are valid options; the user's selection stays. A future iteration may add a "merge" action; out of scope here.
+3. **Empty `networkInterfaces`** — All-interface list is empty. If `query` is also empty, `CommandEmpty` shows. If `query` is valid, the `use-query` entry still appears so the user can type an address even when nothing is enumerated. The trigger shows `No interfaces found`.
+4. **Manual address becomes unreachable at pair time** — Not handled here. The QR generation succeeds; `pair-scan.tsx` already surfaces "Cannot connect — same network?" on failure.
+5. **Closing the popover with an invalid query typed** — `customAddress` and `selectedAddress` are unchanged. Next open starts with an empty `query`.
+
+## Testing
+
+**`src/shared/network/manual-address.test.ts`**
+
+- Accepts: `0.0.0.0`, `255.255.255.255`, `192.168.1.24`, `100.64.1.20`.
+- Rejects: `''`, `'   '`, `'1.2.3'`, `'1.2.3.4.5'`, `'256.0.0.1'`, `'01.02.03.04'` (leading zeros), `'192.168.1.24 '` (trailing space).
+- Accepts MagicDNS: `my-mac.ts.net`, `my-mac.tail-abcd.ts.net`, `a.b.c.d.ts.net`.
+- Rejects MagicDNS: `my-mac` (no `.ts.net`), `my-mac.ts.com`, `-foo.ts.net`, `MY-MAC.TS.NET` is accepted (case-insensitive).
+- Rejects anything > 253 chars; rejects whitespace anywhere.
+- Pure unit tests; no React, no mocks.
+
+**`mobile-network-interface-selection.test.ts`**
+
+- `buildComboboxEntries([LAN, TAILNET], '')` returns two interface entries, no `use-query`.
+- `buildComboboxEntries([LAN, TAILNET], '100')` (invalid query) returns the tailnet interface only — substring filter on `100.64.1.20` matches `100` — and no `use-query` because the query did not parse.
+- `buildComboboxEntries([LAN, TAILNET], '100.64.1.20')` (valid query) returns both interface entries (valid queries skip substring filtering) AND suppresses `use-query` because the parsed address equals an existing interface's `address`.
+- `buildComboboxEntries([LAN, TAILNET], 'my-mac.tail-abcd.ts.net')` (valid query) returns both interface entries (valid queries skip substring filtering) plus a `use-query` with the trimmed address.
+- `buildComboboxEntries([], '1.2.3.4')` returns just `use-query`.
+
+**`MobileNetworkInterfaceSection.test.tsx`** (new)
+
+- Open popover, type `100.64.1.20`, click `Use "100.64.1.20"` → trigger label becomes `100.64.1.20 (custom)`, query clears.
+- Type `not-an-address` → error message renders, no `Use …` row.
+- Type `192.168.1.24` (matches `en0`) → no `Use …` row; clicking the existing interface selects it as `en0`, not `custom`.
+- Trigger label `No interfaces found` shown when `networkInterfaces` is empty and no manual selection.
+
+## Out of scope
+
+- Persistent storage of manual addresses across sessions (user explicitly chose session-scoped).
+- IPv6, port suffixes, non-Tailscale hostnames (rejected by the parser).
+- Mobile-side endpoint override (separate flow; see `mobile/app/pair-scan.tsx`).
+- Main-process changes — the renderer has enough information already.
+
+## Open questions for reviewer
+
+1. Should the error message stay in English-only here, or get the same `translate('auto.…', 'fallback')` wrap as the rest of the section? Recommend: wrap it for consistency, since the rest of the component already uses `translate()`.
+2. Should `customAddress` survive a "Refresh" click? Recommend yes — user might be mid-typing during a VPN reconnect. Confirmed in Edge case 5 above.
+3. Should `CommandInput` accept paste of a multi-line string (e.g. user pastes `orca://pair?code=…`)? Recommend: no special handling; the existing trim+validate treats it as an invalid address and shows the error. Pair-URL paste remains the path through `pair-scan.tsx`.

+# Headless Linux Server
+
+Use this guide when you want to run `orca serve` on a Linux machine without a
+desktop session, such as an Ubuntu VPS or a remote build box.
+
+`orca serve` starts the Orca runtime without opening the desktop window. On
+Linux, the packaged AppImage still needs the libraries that Electron expects at
+startup. Current Orca builds can start Xvfb automatically for `orca serve` when
+no `DISPLAY` is set, but Xvfb must be installed first. When `DISPLAY` is set,
+Orca uses that display instead of starting a competing Xvfb process.
+
+## Ubuntu 22.04 Prerequisites
+
+Install the AppImage runtime dependency and Xvfb:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y curl libfuse2 xvfb
+```
+
+Download and make the AppImage executable:
+
+```bash
+sudo mkdir -p /opt/orca
+sudo curl -L https://github.com/stablyai/orca/releases/latest/download/orca-linux.AppImage \
+  -o /opt/orca/orca-linux.AppImage
+sudo chmod +x /opt/orca/orca-linux.AppImage
+```
+
+If `Xvfb` was installed somewhere other than `/usr/bin`, confirm systemd can
+find it later:
+
+```bash
+command -v Xvfb
+```
+
+## Run In The Foreground
+
+Start with a foreground run before creating a service:
+
+```bash
+LIBGL_ALWAYS_SOFTWARE=1 /opt/orca/orca-linux.AppImage serve --port 6768
+```
+
+For remote clients, pass the address they should use to reach this server. A
+Tailscale address is usually the safest option for private servers:
+
+```bash
+LIBGL_ALWAYS_SOFTWARE=1 /opt/orca/orca-linux.AppImage serve \
+  --port 6768 \
+  --pairing-address 100.64.1.20
+```
+
+The command prints the runtime endpoint and pairing URL. Stop it with `Ctrl+C`.
+
+## Systemd Service
+
+Create a dedicated service user and install directory. Run the service as this
+user instead of root so the AppImage can keep Chromium's sandbox enabled.
+
+```bash
+sudo useradd --system --create-home --shell /usr/sbin/nologin orca
+sudo chown -R orca:orca /opt/orca
+```
+
+For most hosts, one `orca serve` service is enough because Orca starts Xvfb on
+display `:99` when no display exists:
+
+```ini
+# /etc/systemd/system/orca-serve.service
+[Unit]
+Description=Orca runtime server
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=simple
+User=orca
+WorkingDirectory=/home/orca
+Environment=LIBGL_ALWAYS_SOFTWARE=1
+ExecStart=/opt/orca/orca-linux.AppImage serve --port 6768 --pairing-address 100.64.1.20
+Restart=on-failure
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Replace `100.64.1.20` with the LAN, Tailscale, tunnel, or public hostname that
+clients should use.
+
+Enable the service:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable --now orca-serve.service
+sudo journalctl -u orca-serve.service -f
+```
+
+## Managed Xvfb Service
+
+If you prefer to own the virtual display lifecycle in systemd, run Xvfb as a
+separate service and set `DISPLAY=:99` for Orca.
+
+```ini
+# /etc/systemd/system/orca-xvfb.service
+[Unit]
+Description=Virtual X display for Orca
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=simple
+ExecStart=/usr/bin/Xvfb :99 -screen 0 1280x1024x24 -nolisten tcp
+Restart=on-failure
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+If `command -v Xvfb` returned a different path, update `ExecStart` to that
+absolute path.
+
+Then add the display dependency to the Orca service:
+
+```ini
+# /etc/systemd/system/orca-serve.service
+[Unit]
+Description=Orca runtime server
+After=network-online.target orca-xvfb.service
+Wants=network-online.target orca-xvfb.service
+
+[Service]
+Type=simple
+User=orca
+WorkingDirectory=/home/orca
+Environment=DISPLAY=:99
+Environment=LIBGL_ALWAYS_SOFTWARE=1
+ExecStart=/opt/orca/orca-linux.AppImage serve --port 6768 --pairing-address 100.64.1.20
+Restart=on-failure
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable both units:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable --now orca-xvfb.service orca-serve.service
+```
+
+## CLI Install Note
+
+On a headless host, you do not need to open the desktop UI just to run the
+server. Invoke the AppImage directly:
+
+```bash
+/opt/orca/orca-linux.AppImage serve --help
+```
+
+If you later install the desktop CLI from Orca settings, use that CLI for normal
+shell workflows. Keep the AppImage path in systemd so service restarts do not
+depend on an interactive shell profile.
+
+## Troubleshooting
+
+- `dlopen(): error loading libfuse.so.2`: install `libfuse2`.
+- `Missing X server or $DISPLAY`: install `xvfb`, or start the managed Xvfb
+  service and set `DISPLAY=:99`.
+- `Xvfb not found`: confirm `command -v Xvfb` and use that absolute path in the
+  systemd unit.
+- GPU or DRI warnings on a VPS: keep `LIBGL_ALWAYS_SOFTWARE=1` in the service
+  environment.
+- Chromium sandbox errors: confirm the service is running as the non-root
+  `orca` user and that `/opt/orca` is readable by that user.
+- Clients cannot connect: make sure `--pairing-address` is an address reachable
+  from the client, and make sure firewalls allow the selected `--port`.
+- Diagnosing other missing libraries: extract the AppImage without launching it
+  with `./orca-linux.AppImage --appimage-extract`, then run
+  `ldd squashfs-root/orca` to list any shared libraries the host is missing.

+# Manual Network Address Entry — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let users type a custom IPv4 address or Tailscale MagicDNS hostname into the desktop mobile-pairing Network Interface dropdown, so the QR code can target a host the OS hasn't auto-discovered.
+
+**Architecture:** Replace the inner `Select` of `MobileNetworkInterfaceSection` with a `Popover + Command` ("combobox") pattern modeled on the existing `AgentCombobox`. A new shared pure function `parseManualNetworkAddress` enforces the input grammar; a new helper `buildComboboxEntries` builds the row list (filtered interfaces + an optional `Use "<query>"` row). The custom selection is session-scoped.
+
+**Tech Stack:** TypeScript, React 18, shadcn/ui primitives (`Command`, `Popover`, `Button`) from `src/renderer/src/components/ui/`, vitest, `@testing-library/react`. No new dependencies.
+
+**Spec:** [`docs/reference/2026-06-27-orca-mobile-manual-network-address-design.md`](../2026-06-27-orca-mobile-manual-network-address-design.md)
+

+
+## File map
+
+**Create:**
+- `src/shared/network/manual-address.ts` — pure parser.
+- `src/shared/network/manual-address.test.ts` — parser unit tests.
+- `src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx` — UI render tests.
+
+**Modify:**
+- `src/renderer/src/components/settings/mobile-network-interface-selection.ts` — swap `mergeForSelect` for `buildComboboxEntries` (or add `buildComboboxEntries` and keep the old one if other call sites exist; confirm with grep before deleting).
+- `src/renderer/src/components/settings/mobile-network-interface-selection.test.ts` — replace `mergeForSelect` tests with `buildComboboxEntries` tests.
+- `src/renderer/src/components/settings/MobileNetworkInterfaceSection.tsx` — swap `Select` for `Popover + Command`.
+
+**Reference (read-only, do not modify):**
+- `src/renderer/src/components/ui/command.tsx` — `Command`, `CommandEmpty`, `CommandInput`, `CommandItem`, `CommandList`, `CommandSeparator`.
+- `src/renderer/src/components/ui/popover.tsx` — `Popover`, `PopoverTrigger`, `PopoverContent`.
+- `src/renderer/src/components/ui/button.tsx` — `Button`.
+- `src/renderer/src/components/agent/AgentCombobox.tsx` — full reference implementation of the controlled cmdk pattern.
+- `src/renderer/src/components/agent/agent-combobox-command-state.ts` — `createAgentComboboxCommandState`, `resolveAgentComboboxCommandState`, `updateAgentComboboxCommandValue`.
+- `src/renderer/src/components/settings/MobilePairingQrSection.tsx` — consumer of `selectedAddress`; unchanged.

+
+  Replace the entire file with:
+
+  ```ts

+
+  The relative import paths (`../../../../shared/tailnet-address`, `../../../../shared/network/manual-address`) must match the file's location in the tree. If they don't resolve, adjust based on the existing path style in the same directory (e.g. `../foo` vs `@/foo`).

+## Task 3: Rewrite `MobileNetworkInterfaceSection` UI to use Popover + Command
+
+**Files:**
+- Modify: `src/renderer/src/components/settings/MobileNetworkInterfaceSection.tsx`
+- Create: `src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx`
+
+- [ ] **Step 1: Read `AgentCombobox.tsx` end-to-end**
+
+  Read `src/renderer/src/components/agent/AgentCombobox.tsx` and `agent-combobox-command-state.ts` in full. You will be borrowing:
+  - The `Popover` + `Command` + `CommandInput` + `CommandList` + `CommandItem` JSX structure.
+  - The controlled `commandState`/`commandValue` pattern that mirrors `AgentCombobox`.
+  - The `setInputNode`/`focusSearchInput` pattern for keyboard accessibility.
+
+  Do not import agent-specific helpers (e.g. `searchAgentPickerEntries`, `agent-combobox-command-state` is shared but the search logic isn't needed here).
+
+- [ ] **Step 2: Read the current `MobileNetworkInterfaceSection.tsx` in full**
+
+  Read the file. Note the props contract:
+  ```ts
+  type MobileNetworkInterfaceSectionProps = {
+    networkInterfaces: MobileNetworkInterface[]
+    selectedAddress: string | undefined
+    onSelectedAddressChange: (address: string) => void
+    refreshingNetworkInterfaces: boolean
+    onRefreshNetworkInterfaces: () => void
+    loading: boolean
+    hasQrCode: boolean
+    onGenerateQr: () => void
+  }
+  ```
+  The contract **must not change** — only the inner control does. `MobilePairingQrSection.tsx` consumes `selectedAddress` and is unaffected.
+
+- [ ] **Step 3: Write the failing render tests**
+
+  Create `src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx`:
+
+  ```tsx
+  import React from 'react'
+  import { describe, it, expect, vi } from 'vitest'
+  import { render, screen } from '@testing-library/react'
+  import userEvent from '@testing-library/user-event'

+  import type { MobileNetworkInterface } from './mobile-network-interface-selection'
+
+  const LAN: MobileNetworkInterface = { name: 'en0', address: '192.168.1.24' }
+  const TAILNET: MobileNetworkInterface = { name: 'tailscale0', address: '100.64.1.20' }
+
+  function renderSection(overrides: Partial<React.ComponentProps<typeof MobileNetworkInterfaceSection>> = {}) {

+
+  Notes for the implementer:
+  - `Command shouldFilter={false}` because we already filter in `buildComboboxEntries`. Without this, cmdk's default fuzzy filter would re-filter the manually-injected `__use__` row out of view.
+  - The `value` prop on each `CommandItem` keeps cmdk happy but does not affect our filtering; we own filtering.
+  - `useMemo` is used for `selectedIface`, `entries`, and `queryParse` so re-renders triggered by parent prop changes don't churn the combobox state.
+  - If `isCustomLabel` is unused after a lint pass (no caller in the final file), delete the helper — the spec lists it but the implementation inlines the check.
+
+- [ ] **Step 6: Run the new test file**
+
+  ```bash
+  pnpm vitest run src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx
+  ```
+  Expected: all six tests pass.
+
+  If any fail:
+  - `toHaveTextContent` mismatches → check the trigger label format.
+  - `getByRole('option', { name: /Use "…"/ })` not found → verify `Command shouldFilter={false}` is set.
+  - Inline error not appearing → verify `showInlineError` is computed against `queryParse.ok`.
+
+- [ ] **Step 7: Run the full test suite for the settings folder**
+
+  ```bash
+  pnpm vitest run src/renderer/src/components/settings/
+  ```
+  Expected: all green. Confirm nothing else broke (e.g. `MobilePairingQrSection.test.tsx` if it exists).
+
+- [ ] **Step 8: Lint, typecheck, build**
+
+  ```bash
+  pnpm lint
+  pnpm typecheck
+  pnpm build
+  ```
+  Expected: all green. If `pnpm lint` complains about an unused import (e.g. `isCustomLabel` or `CommandSeparator`), remove it and re-run.
+
+- [ ] **Step 9: Commit**
+
+  ```bash
+  git add src/renderer/src/components/settings/MobileNetworkInterfaceSection.tsx \
+          src/renderer/src/components/settings/MobileNetworkInterfaceSection.test.tsx
+  git commit -m "feat(mobile-pairing): combobox with manual address entry"
+  ```
+

+
+## Task 4: End-to-end verification & PR prep
+
+**Files:** none modified; verification only.
+
+- [ ] **Step 1: Run the four CI checks locally**
+
+  ```bash
+  pnpm lint
+  pnpm typecheck
+  pnpm test
+  pnpm build
+  ```
+  Expected: all green. This is exactly what `.github/workflows/` runs.
+
+- [ ] **Step 2: Manual smoke check**
+
+  If Orca can be launched locally with the desktop build:
+  1. Open Settings → Mobile.
+  2. Click the Network Interface dropdown — confirm both interfaces list.
+  3. Type a tailnet address — confirm the `Use "…"` row appears.
+  4. Click `Use "…"` — confirm the trigger switches to `… (custom)`.
+  5. Click Refresh — confirm the custom selection survives.
+  6. Type an invalid string — confirm the inline error appears and no `Use …` row is shown.
+  7. Type an address that already matches an interface (e.g. `192.168.1.24`) — confirm the `Use` row is hidden and selecting the interface row does NOT show `(custom)`.
+
+  Skip any step that requires a running desktop build and note it in the PR description.
+
+- [ ] **Step 3: Capture before/after screenshots**
+
+  Save screenshots to a temp directory (NOT to the repo — `CONTRIBUTING.md` and `AGENTS.md` forbid committing PR evidence images). Use gstack browse if running the production binary:
+  ```bash
+  $HOME/.claude/skills/gstack/browse/dist/browse screenshot /tmp/orca-mobile-section-before.png --selector ...
+  ```
+  Attach the screenshots to the PR conversation (never use `gh-attach`).
+
+- [ ] **Step 4: Push the branch and draft the PR**
+
+  ```bash
+  git push origin HEAD
+  gh pr create \
+    --title "feat(mobile-pairing): combobox with manual network address entry" \
+    --body-file /tmp/pr-body.md
+  ```
+
+  The PR body should follow `pull_request_template.md`:
+  - **Summary:** explain that the desktop Network Interface dropdown now accepts a manually-typed IPv4 or Tailscale MagicDNS hostname.
+  - **Screenshots:** link to the conversation-attached screenshots.
+  - **Testing:** check all four `pnpm` boxes; note that `pnpm test` includes the three new test files (`manual-address.test.ts`, `mobile-network-interface-selection.test.ts`, `MobileNetworkInterfaceSection.test.tsx`).
+  - **AI Review Report:** confirm the review checked cross-platform (no platform-specific code; uses shadcn primitives + cmdk patterns already in the codebase), SSH/remote/local compatibility (no change to main-process IPC), agent/integration compatibility (no change), performance (UI re-render cost is bounded by `useMemo` over the interface list), UI quality (follows STYLEGUIDE.md; uses `text-statusRed` for the error), security (no new IPC; the address flows through the existing `selectedAddress` prop which `MobilePairingQrSection` already validated).
+  - **Security Audit:** no new IPC, no new auth surface, no new dependency, no new env var. The parser rejects malformed input early so the QR endpoint never sees invalid data.
+  - **Notes:** none — single platform-agnostic renderer change.
+  - **X handle:** include the contributor's X handle per CONTRIBUTING.md so maintainers can shout out.
+
+- [ ] **Step 5: Request review**
+
+  ```bash
+  gh pr edit --add-reviewer <maintainer-handle>
+  ```
+  Or comment `@<maintainer>` in the PR if reviewer auto-assignment isn't available.

+# Terminal Switch Typing Lag Investigation
+
+Date: 2026-07-01
+
+## Scope
+
+This note tracks the investigation into terminal input lag that appears after switching workspaces or terminals in a heavy packaged Orca profile.
+
+The user-visible symptom is that typing after switching back to a workspace can feel delayed for about one second. Text may appear all at once after the delay. The issue reproduced in the user's main packaged Orca app, but not reliably in lighter dev profiles.
+
+## Current Reproduction Setup
+
+- Main packaged Orca app is used for the meaningful repro.
+- The main profile had roughly 150 terminals when the lag reproduced.
+- The current worktree under test is `/Users/jinwoohong/orca/workspaces/orca/osprey`.
+- The main app did not expose CDP, so browser-level renderer profiling was limited.
+- The harness creates a throwaway bash terminal, switches away and back, sends a marker command, waits for a receipt file, and closes the throwaway terminal.
+- Harness path: `.tmp/terminal-main-app-typing-lag/probe.mjs`
+- The strongest repro switches through an old, output-rich workspace before typing in the probe terminal.
+- Current deterministic alternate terminal:
+  `term_4d7a0b50-e9ae-420e-ac5d-7ec12cbfa408` in the `triage-issues` workspace.
+
+Useful harness modes:
+
+```sh
+ORCA_PROBE_RUNS=8 ORCA_PROBE_FOCUS_EACH_RUN=0 ORCA_PROBE_TYPE_MODE=terminal-send ORCA_PROBE_RECEIPT_MODE=file node .tmp/terminal-main-app-typing-lag/probe.mjs

+```
+
+## Key Measurements
+
+### 2026-07-01 follow-up: cold visit vs warm revisit
+
+After the metadata-only `listSessions()` fix, the user reported a sharper
+pattern:
+
+- First visit to a terminal, where the terminal briefly shows blank while the
+  renderer/webgl surface loads, does not show the typing lag.
+- Revisiting that same already-mounted terminal brings the lag back.
+
+Code-level reproduction:
+
+- `connectPanePty` previously armed a one-shot input liveness check from
+  `noteVisibilityResume()`.
+- The first `xterm.onData` input after a warm visibility resume called
+  `window.api.pty.listSessions()` before forwarding the byte with
+  `transport.sendInput(data)`.
+- A focused unit regression captured the bad order as
+  `["listSessions", "sendInput"]`.
+
+Fix direction:
+
+- Terminal input no longer starts a renderer→main→daemon session enumeration.
+- Hidden→visible lifecycle reconciliation and daemon missing-session exit events
+  remain responsible for stale pane cleanup.
+- The focused regression now asserts that repeated warm resumes plus typing
+  produce zero `listSessions()` calls from the input handler.
+
+### 2026-07-01 follow-up: preserved old daemon after input fix
+
+After the input-handler fix, the main packaged profile still reproduced the
+warm-switch lag because the live v18 daemon was preserved from an older build:
+
+- Fresh main-profile repro:
+  `.tmp/terminal-main-app-typing-lag/result-2026-07-01T09-59-08-111Z.json`
+- Direct daemon writes after switching took 661, 982, 998, 980, and 1000 ms.
+- Receipt latency after the daemon write returned stayed low at 77-85 ms.
+- No-switch control:
+  `.tmp/terminal-main-app-typing-lag/result-2026-07-01T09-59-28-346Z.json`
+  ended with fast direct daemon writes once the probe terminal settled.
+
+The remaining source hot path was the visibility-resume dead-session sweep:
+
+1. Switching a warm terminal hidden→visible ran the lifecycle visibility effect.
+2. The effect scheduled `reconcileDeadSessions`.
+3. `reconcileDeadSessions` invoked `window.api.pty.listSessions()`.
+4. A preserved old daemon still implemented `listSessions` by snapshotting every
+   live session, so the user's next daemon `write` queued behind that work.
+
+Fix:
+
+- Replace the automatic visibility-resume `listSessions()` sweep with a targeted
+  single-session liveness check.
+- Main exposes `pty:hasPty(id)`, which reads provider-owned in-memory PTY state
+  and returns `null` when the provider cannot answer authoritatively.
+- Renderer visible-resume asks only about each mounted pane's current PTY id.
+  The pane tears down only on an authoritative `false`; `true`, `null`, rejected
+  checks, remote-runtime ids, SSH ids, and stale/newborn races all fail open.
+- Keep visibility resume process tracking and PTY-size reassertion intact.
+- This preserves the recovery added by `a9ef6f916` for panes that missed
+  `pty:exit` while hidden, without putting a daemon-wide session enumeration on
+  the warm-switch/input path.
+
+Verification:
+
+- Focused vitest suite: `508` tests passed across terminal lifecycle,
+  pty-connection, dead-session reconcile, and PTY IPC.
+- Headful fullscreen E2E harness:
+  `tests/e2e/terminal-warm-switch-no-list-sessions.tmp.spec.ts`
+  wraps main-process `pty:listSessions` with an 800 ms stall and then switches
+  warm workspaces and types into the terminal.
+- Latest E2E artifact:
+  `.tmp/terminal-warm-switch-no-list-sessions/result-1782929853828.json`
+  showed `fullscreen: true`, `listSessionCallCount: 0`, and
+  `postTypeEchoLatencyMs: 10`.
+
+### CLI `terminal-send`, switch away/back
+
+Result file: `.tmp/terminal-main-app-typing-lag/result-2026-07-01T06-59-45-098Z.json`
+
+- Average echo latency was about 1841 ms.
+- Receipt latency was roughly 836-1445 ms.
+
+### CLI `terminal-send`, no switch
+
+- Average echo latency was about 312 ms.
+
+### CLI `terminal-send`, switch away/back, 1000 ms settle before send
+
+- Average echo latency was about 574 ms.
+- Receipt latency was mostly 1-227 ms, with one run around 684 ms.
+- This suggests the problematic window is bounded and concentrated immediately after switch/resume.
+
+### Direct daemon request, switch away/back
+
+Result file: `.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-04-43-497Z.json`
+
+- The harness opened its own daemon control socket and sent the real daemon `write` request directly.
+- Daemon write response time was roughly 947-1142 ms.
+- Receipt latency after the daemon write response was about 76 ms.
+- Average echo latency was about 1385 ms.
+
+### Direct daemon request, no switch
+
+Result file: `.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-05-12-496Z.json`
+
+- Daemon write response time was 0-45 ms.
+- Receipt latency was roughly 76-85 ms.
+- Average echo latency was about 258 ms.
+
+### Direct daemon request, output-rich workspace switch
+
+Result file: `.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-22-06-789Z.json`
+
+- The alternate terminal was `term_4d7a0b50-e9ae-420e-ac5d-7ec12cbfa408` in the `triage-issues` workspace.
+- All four runs delayed.
+- Direct daemon `write` response times were 1566, 1527, 1477, and 1333 ms.
+- Average echo latency was about 1790 ms.
+- A daemon CPU sample was captured at `.tmp/terminal-main-app-typing-lag/daemon-71111-sample-20260701032206.txt`.
+
+Latest reproduced run:
+`.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-27-25-513Z.json`
+
+- Two runs after switching through `triage-issues`.
+- Direct daemon `write` response times were 1556 and 1582 ms.
+- Receipt latency after the daemon write response was about 76-77 ms.
+- This confirms the daemon request itself waits; once it returns, the PTY and shell process the input quickly.
+
+### Direct daemon ping loop during switch
+
+A direct daemon client sent `ping` requests every roughly 50 ms while the harness issued `orca terminal switch` away and back.
+
+- Pings before and after the switch were effectively immediate.
+- One ping sent around 469 ms after switch start waited 1212 ms.
+- No terminal input was involved in this probe.
+
+This is the strongest evidence so far that workspace/terminal switching creates a daemon event-loop stall. The typing lag is a user-visible symptom of the same stall, not the root trigger.
+
+### Direct daemon request, no switch
+
+Latest no-switch result:
+`.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-27-58-622Z.json`
+
+- First run had a direct daemon `write` response of 571 ms, likely a new-probe/settling artifact.
+- Next two runs were 0-1 ms.
+- No-switch is generally fast once the probe terminal is settled.
+
+### Pause after switching away
+
+- Adding `ORCA_PROBE_AFTER_SWITCH_AWAY_MS=1500` before switching back made direct daemon writes fast again.
+- This indicates expensive work starts when Orca switches into or resumes the output-rich workspace, then spills into the immediate switch-back/write window.
+
+Latest pause-control result:
+`.tmp/terminal-main-app-typing-lag/result-2026-07-01T07-29-58-568Z.json`
+
+- Direct daemon `write` response times were 0, 0, and 0 ms.
+- Echo latency was about 343-363 ms.
+- This bounds the problematic window to roughly the first 1-1.5 seconds after switching into/through the expensive workspace.
+
+### Synthetic heavy terminals
+
+- Synthetic split panes with large scrollback were not enough to reproduce reliably.
+- A plain heavy scrollback split reproduced once in four runs, then larger synthetic scrollback stayed fast.
+- A synthetic TUI repaint split stayed fast.
+- The issue is therefore not simply "large output" or "any hidden repaint"; old retained/reattach/snapshot state is still suspect.
+
+### Output timestamp check
+
+- `lastOutputAt` did not advance when switching through the `triage-issues` terminal and away.
+- That weakens the theory that a resume-triggered SIGWINCH caused the child TUI to emit a fresh repaint burst.
+- The delay can happen without fresh PTY output from the child process.
+
+### Snapshot and resize controls
+
+Direct `getSnapshot` probes on real sessions were much cheaper than the observed lag:
+
+- Output-rich `triage` terminal: about 10 ms, roughly 122 KB response.
+- Active `osprey` Codex terminal: about 57 ms, roughly 804 KB response.
+
+Synthetic resize pulses on throwaway heavy-scrollback terminals were also cheap:
+
+- Background 80x24 resize pulse: about 2 ms.
+- Focused 232x86 resize pulse: about 2 ms.
+
+These controls weaken the idea that one ordinary snapshot or one ordinary resize explains a 1.2-1.6 second stall. The remaining suspicious shape is switch-time fanout: many warm reattachments, snapshots, visibility/resume requests, pending-output drains, or checkpoint-like work running serially in the daemon.
+
+### Daemon `listSessions` proof
+
+The daemon-only measurement identified the blocking request:
+
+```json
+[
+  { "type": "ping", "elapsedMs": 0 },
+  { "type": "listSessions", "elapsedMs": 552, "count": 137 },
+  { "type": "ping", "elapsedMs": 0 },
+  { "type": "listSessions", "elapsedMs": 547, "count": 137 },
+  { "type": "ping", "elapsedMs": 0 }
+]
+```
+
+A second daemon-only queue test sent two `listSessions` requests and then a `ping` from another client:
+
+```json
+{
+  "totalMs": 1069,
+  "listSessions1Ms": 1068,
+  "listSessions2Ms": 1068,
+  "pingBehindListSessionsMs": 1034,
+  "sessions": 137
+}
+```
+
+This reproduces the same stall shape without terminal input or UI switching: a control request sent behind resume-time `listSessions` waits about one second.
+
+Source cause:
+
+- `TerminalHost.listSessions()` loops every live daemon session.
+- For each session, it calls `session.getSnapshot()` only to read `cols` and `rows`.
+- `getSnapshot()` serializes the headless xterm buffer, so a liveness/session-list request scales with terminal scrollback/state across the whole profile.
+- Renderer visibility resume calls `window.api.pty.listSessions()` for dead-session reconciliation. With about 137 live daemon sessions, one resume-time list was about 550 ms; two back-to-back resumes were about 1.0-1.1 seconds.
+
+## What This Rules Out
+
+- It is probably not keyboard focus. Direct daemon writes reproduce the delay.
+- It is probably not only renderer paint. Direct daemon writes wait before the shell receives bytes.
+- It is probably not bash or node-pty readiness. No-switch direct writes are fast, and receipt latency after a delayed daemon response is low.
+- It is probably not queueing only on Orca's normal daemon client socket. The direct-daemon harness uses a separate socket and still sees the delay.
+- It is not caused by typing itself. A ping loop with no write showed the daemon stall during switching.
+- It is unlikely to be a single normal `getSnapshot` or `resize` call, because direct controls for those operations are much cheaper than the observed stall.
+- The resume-time dead-pane recovery is still necessary; the hot path should
+  use single-PTY liveness, not a global session list.
+
+## Current Conclusion
+
+Switching workspaces or terminals can create a short daemon/main busy window
+when warm resume triggers global session enumeration. During that window, even a
+direct terminal `write` request waits before the daemon services it. Once the
+daemon services the write, the shell receives and processes the bytes quickly.
+
+The confirmed root for the remaining warm-switch lag is the visibility-resume
+dead-session reconciliation path calling global `listSessions()` in profiles
+with many preserved daemon sessions. The original dead-session recovery is valid;
+the expensive primitive was the problem.
+
+## Leading Hypotheses
+
+1. Confirmed: resume-time dead-session reconciliation called daemon
+   `listSessions`, and older daemons synchronously snapshot every live session
+   to return cols/rows.
+2. Confirmed: avoiding global `listSessions()` on warm resume removes the
+   request that queued ahead of first post-switch input.
+3. Possible secondary contributor: switching to certain old or output-rich
+   workspaces may also reattach existing daemon-backed PTYs. The daemon
+   `createOrAttach` path synchronously calls `existing.getSnapshot()` before
+   responding.
+4. Possible secondary contributor: hidden-output recovery, pending-output
+   draining, or another snapshot-like serialization path runs synchronously on
+   resume and delays request handling.
+5. Less likely: workspace or terminal resume triggers visible-terminal
+   resize/SIGWINCH or TUI repaint output. The unchanged `lastOutputAt`
+   observation currently makes this less likely than `listSessions`.
+
+## Relevant Code Areas
+
+- CLI terminal send: `src/cli/handlers/terminal.ts`
+- Runtime terminal send/focus/write: `src/main/runtime/orca-runtime.ts`
+- Runtime PTY data handling: `onPtyData`, `trackHeadlessTerminalData`, hidden-output serialization in `src/main/runtime/orca-runtime.ts`
+- Daemon request routing: `src/main/daemon/daemon-server.ts`

+- Renderer terminal resume: `src/renderer/src/components/terminal-pane/terminal-visibility-resume.ts`
+- Renderer PTY connection and resume size reassertion: `src/renderer/src/components/terminal-pane/pty-connection.ts`
+- Renderer output scheduler: `src/renderer/src/lib/pane-manager/pane-terminal-output-scheduler.ts`
+- Existing-session reattach snapshot: `TerminalHost.createOrAttach` in `src/main/daemon/terminal-host.ts`
+- Session snapshot serialization: `TerminalSession.getSnapshot()` in `src/main/daemon/session.ts`
+- Snapshot cost benchmark: `src/main/daemon/headless-emulator-snapshot-cost.bench.test.ts`
+
+## Current Root-Cause Theory
+
+The root cause is using global session enumeration as a per-pane liveness check:
+
+1. Workspace switching makes a terminal pane visible again.
+2. The renderer schedules dead-session reconciliation on hidden-to-visible resume.
+3. The old reconcile path called `window.api.pty.listSessions()`, which reaches
+   the daemon `listSessions` RPC.
+4. Older preserved daemons implement `TerminalHost.listSessions()` by calling
+   `session.getSnapshot()` for every live session.
+5. With a heavy profile, those snapshot serializations block the daemon event
+   loop for about 550 ms per list.
+6. A switch away/back can put a `write` behind two resume-time lists, yielding
+   about 1.0-1.6 seconds of delayed input.
+
+This theory fits the current evidence:
+
+- Direct daemon writes block, so the delay is below keyboard focus and normal CLI plumbing.
+- Receipt handling after the daemon write response is fast, so the shell and PTY are not the bottleneck.
+- No-switch writes are fast.
+- Waiting after switching away lets the expensive resume work finish, so switching back and typing is fast.
+- `lastOutputAt` does not advance, so the child process probably is not generating the expensive work.
+- Synthetic fresh heavy output did not reproduce reliably, which points toward retained old session/state, request fanout, or workspace-specific resume behavior rather than simple line count.
+
+The correct fix is two-layered:
+
+1. Keep daemon `listSessions` metadata-only for builds where callers genuinely
+   need the global session list.
+2. Do not use `listSessions` for warm-resume dead-pane recovery. Use
+   `pty:hasPty(id)` to ask about the pane's own PTY id, backed by provider
+   in-memory state. Close only on authoritative `false`; fail open on `true`,
+   `null`, unsupported providers, remote-runtime/SSH ids, and stale/newborn
+   races.
+
+## Investigation Constraints
+
+- Do not kill or restart the user's main packaged Orca app or daemon without explicit approval.
+- Use throwaway terminals for probes and close them afterward.
+- Keep temp harnesses and screenshots out of commits unless explicitly requested.
+- Reproduce in the real main-app flow when possible; lighter dev profiles may not show the problem.
+
+## Verification Plan
+
+1. Unit-test that `pty:hasPty(id)` does not call provider `listProcesses()`.
+2. Unit-test that targeted liveness still closes a missing local PTY and fails
+   open for live/unknown/stale cases.
+3. Unit-test that terminal input and warm resume do not call `listSessions()`.
+4. Re-run the headful fullscreen warm-switch E2E with `pty:listSessions`
+   artificially delayed and assert the count stays zero.
+5. Re-run the main-app direct-daemon switch/no-switch harness when validating
+   against the user's heavy profile.

+# Terminal Scroll Intent Architecture
+
+## Problem
+
+Terminal panes can jump or jitter when a user switches workspaces while a TUI
+pane is scrolled near, but not exactly at, the bottom. The most visible case is a
+Codex-style alternate-screen TUI in a split pane:
+
+1. The user scrolls slightly up from the bottom.
+2. The user switches to another workspace.
+3. The user switches back.
+4. The terminal sometimes jumps to the top, jumps to the bottom, flashes at a
+   wrong position, or restores an older viewport.
+
+The current code tries to repair the viewport after layout, fit, split
+reparenting, hidden-output replay, and visibility resume. Those repairs compete
+with each other because none of them owns the user's scroll intent. A delayed
+restore can replay an old state after the user has already scrolled, while a
+follow-output path can force the bottom even when the user is reading scrollback.
+
+## Reference Investigation Summary
+
+The useful reference pattern is not a timer-based restore loop. It is an
+explicit pinned-to-bottom model owned by the terminal frontend:
+
+- The frontend stores bottom-following state separately from xterm's transient
+  `viewportY`.
+- `xterm.onScroll` is not used as user intent. In xterm, that event can be
+  content-driven and can briefly report bottom during fast output or layout work.
+- User wheel and keyboard scroll commands update the intent.
+- `scrollToBottom()` is an explicit command that sets the intent back to
+  follow-output.
+- Every write snapshots the intent before writing. If the terminal was following
+  output, it scrolls to bottom after the write. If the user was pinned to a
+  viewport, it preserves the prior viewport line.
+- Fit/resize uses the same rule: follow bottom if explicitly pinned, otherwise
+  preserve the current viewport.
+- Alternate-screen state is tracked from `buffer.active.type`, but it is not a
+  reason to infer user scroll intent from `onScroll`.
+
+The reference implementation also patches private xterm internals to disable
+xterm's implicit scroll-to-bottom behavior and call the original bottom-scroll
+only from explicit owner paths. That gives a clean ownership boundary, but it is
+an escalation point for Orca because private internals increase xterm upgrade
+risk.
+
+## Current Orca Risk Points
+
+The current Orca branch already has several independent scroll actors:
+
+- `src/renderer/src/lib/pane-manager/pane-scroll.ts` captures `viewportY`,
+  `baseY`, bottom state, and sometimes a marker, then restores using immediate,
+  rAF, and timeout paths.
+- `src/renderer/src/lib/pane-manager/pane-tree-ops.ts` captures and restores
+  scroll around `safeFit()`.
+- `src/renderer/src/lib/pane-manager/pane-split-scroll.ts` schedules split
+  reparent restores across rAF and timeout phases.
+- `src/renderer/src/components/terminal-pane/use-terminal-scroll-visibility-memory.ts`
+  listens to `terminal.onScroll` and stores snapshots while visible.
+- `src/renderer/src/components/terminal-pane/pty-connection.ts` writes PTY output
+  through foreground, background, hidden-output skip, snapshot replay, and
+  restore paths.
+- `src/renderer/src/lib/pane-manager/pane-terminal-output-scheduler.ts` can
+  write immediately, enqueue foreground writes, coalesce synchronized output, or
+  drain hidden/background chunks later.
+
+The biggest architectural mismatch is the visibility memory hook's use of
+`terminal.onScroll` as a snapshot trigger. That event is not a reliable user
+scroll signal. During workspace switching, output parsing, hidden replay, or fit
+can make it persist transient positions that later appear as "older position"
+restores.
+
+## Design Goal
+
+Make terminal viewport movement a result of explicit scroll intent, not a side
+effect of visibility, output, or layout timing.
+
+The terminal should have one active scroll intent per pane:
+
+- `followOutput`: the terminal is logically pinned to the live output bottom.
+  New output, explicit focus-follow requests, and fits may keep it at bottom.
+- `pinnedViewport`: the user is reading a specific viewport. New output,
+  workspace switches, hidden-output replay, and fits must not move the viewport
+  except when scrollback pruning or buffer replacement makes the exact line
+  impossible.
+
+## State Model
+
+Add a focused module, for example:
+
+`src/renderer/src/lib/pane-manager/terminal-scroll-intent.ts`
+
+Suggested state:
+
+```ts
+export type TerminalScrollIntentKind = 'followOutput' | 'pinnedViewport'
+
+export type TerminalScrollIntent = {
+  kind: TerminalScrollIntentKind
+  bufferType: 'normal' | 'alternate'
+  viewportY: number
+  baseY: number
+  capturedAt: number
+}
+```
+
+The state should be keyed by the live `Terminal` or by pane leaf identity where
+it needs to survive pane replacement. For normal workspace switches that keep
+the same xterm instance, the live terminal-keyed state should be authoritative.
+
+## Intent Transitions
+
+Only these events should change scroll intent:
+
+- User wheel scrolls upward: set `pinnedViewport` immediately before xterm write
+  callbacks or rAF can pull the viewport back down.
+- User wheel scrolls downward: after xterm applies the scroll, recompute whether
+  the viewport reached bottom. If yes, set `followOutput`; otherwise keep
+  `pinnedViewport`.
+- User keyboard scroll commands: apply the same rules as wheel.
+- Explicit `scrollToBottom()`, "follow output", or focus command with
+  follow-output semantics: set `followOutput`.
+- Programmatic `scrollToTop()` or page/line scroll commands: set
+  `pinnedViewport`, unless the resulting viewport is bottom.
+- Buffer change to alternate screen: record `bufferType`, but do not infer
+  follow-output from `onScroll`.
+- Buffer return to normal screen: recompute from current viewport only if no
+  stronger user intent exists for the normal buffer.
+- Scrollback prune: clamp a pinned viewport to the nearest valid line without
+  changing intent.
+- Terminal remount/replay: restore from durable fallback only if the live xterm
+  instance was actually replaced.
+
+Do not use xterm `onScroll` to set intent. It may still be useful as a passive
+diagnostic signal, but it should not persist authoritative scroll state.
+
+## Write Contract
+
+All PTY output that reaches xterm should pass through one wrapper that enforces
+intent around the actual `terminal.write` call.
+
+Suggested owner:
+
+`src/renderer/src/lib/pane-manager/pane-terminal-output-scheduler.ts`
+
+Contract:
+
+1. Capture intent and current `viewportY` before the write is scheduled.
+2. Execute the write through the existing foreground/background/coalescing path.
+3. After the write has parsed enough for xterm buffer state to be meaningful:
+   - If intent is `followOutput`, scroll to bottom.
+   - If intent is `pinnedViewport`, clamp and restore the saved viewport line.
+4. Do not schedule multi-frame retries for normal output. A single post-write
+   enforcement point should be enough for standard writes.
+
+For foreground synchronized-output holds, the enforcement point should run after
+the held/coalesced frame is released, not for each partial cursor-hide chunk.
+
+For background writes, preserve `pinnedViewport` if the pane is hidden or
+inactive. Hidden output should not silently repin the terminal.
+
+## Fit And Resize Contract
+
+`safeFit()` should stop using generic delayed scroll restoration as its normal
+behavior.
+
+New rule:
+
+1. If dimensions do not change, do nothing.
+2. Before fit, capture current intent and viewport.
+3. Fit.
+4. If intent is `followOutput`, scroll to bottom.
+5. If intent is `pinnedViewport`, restore the saved viewport line clamped to the
+   new `baseY`.
+
+Avoid fitting hidden or zero-geometry panes. Existing geometry guards should
+remain because fitting to transient workspace-switch geometry can send bad sizes
+to the PTY and trigger TUI redraw churn.
+
+## Visibility And Workspace Switch Contract
+
+Workspace switching should not be a scroll operation.
+
+On hide:
+
+- Capture the current intent once.
+- Do not run scroll restore.
+- Do not update intent from `onScroll`.
+- Continue hidden-output throttling/snapshot behavior as today.
+
+On show:
+
+- Reattach or refresh renderer resources as needed.
+- Flush only the bounded amount of hidden output required for the active pane.
+- Apply intent once after the visible output catch-up:
+  - `followOutput` goes to bottom.
+  - `pinnedViewport` stays pinned.
+- Do not run repeated rAF/timeout scroll restores.
+
+If the underlying terminal instance was replaced, use durable fallback state.
+If the instance stayed alive, its live scroll intent is authoritative.
+
+## Hidden Output And Snapshot Replay
+
+Hidden-output snapshot replay is a true fallback path because it clears and
+reconstructs xterm content. It needs scroll handling, but it should still obey
+intent:
+
+- Before snapshot replay, capture intent and viewport.
+- Replay serialized content.
+- Fit only if needed and only with valid visible geometry.
+- Reapply the captured intent once:
+  - `followOutput`: bottom.
+  - `pinnedViewport`: previous viewport line, clamped.
+- Do not let replay set follow-output just because the replayed buffer ends at
+  bottom.
+
+If hidden output arrives while the user is pinned, background catch-up should not
+move the visible viewport on activation.
+
+## Split Reparenting
+
+DOM reparenting can reset browser scroll state and WebGL resources. This is a
+legitimate place for a fallback restore, but it should be scoped:
+
+- Capture intent before reparent.
+- Reparent.
+- Reattach renderer if required.
+- Apply intent once after DOM settles.
+- Avoid restoring alternate-screen scrollback, because alternate screen has no
+  normal scrollback and a TUI owns its cursor.
+
+The current split-specific rAF/timer code should become a local fallback for DOM
+reparenting only, not a general model copied into workspace switching.
+
+## Performance Constraints
+
+The design must preserve Orca's terminal performance priorities:
+
+- Do not keep all hidden terminals hot-rendering.
+- Keep PTY/session/xterm state warm when feasible, but suspend hidden rendering
+  work and throttle hidden output as today.
+- Avoid per-output layout reads. Intent enforcement should read xterm buffer
+  fields, not DOM geometry.
+- Avoid multi-frame restore loops. They cause visible jitter and keep the
+  renderer busy after activation.
+- Keep active-pane hidden-output catch-up bounded. Inactive visible split panes
+  can catch up over later frames.
+- Do not send resize/SIGWINCH unless dimensions actually changed and the
+  renderer is the authoritative size owner.
+
+The intended steady-state cost is one small buffer-state capture per xterm write
+batch, not per byte and not per animation frame.
+
+## Implementation Plan
+
+1. Add `terminal-scroll-intent.ts`.
+   - Track `followOutput` vs `pinnedViewport`.
+   - Provide helpers for user scroll, explicit bottom, write capture, fit
+     capture, and intent enforcement.
+
+2. Replace visibility-memory `onScroll` ownership.
+   - Remove authoritative snapshot updates from `terminal.onScroll`.
+   - Add capture-phase wheel listeners and keyboard scroll command hooks.
+   - Keep `onScroll` only for diagnostics if needed.
+
+3. Route explicit scroll commands through intent helpers.
+   - `scrollToBottom()` sets `followOutput`.
+   - `scrollToTop()`, page up, and line up set `pinnedViewport`.
+   - Downward commands recompute after the command.
+
+4. Wrap output writes.
+   - Add an intent-aware writer boundary in the output scheduler or in a narrow
+     wrapper used by the scheduler.
+   - Ensure foreground coalescing applies intent after the coalesced frame.
+   - Ensure background drains preserve pinned viewports.
+
+5. Convert `safeFit()` to intent-aware fit.
+   - Capture intent before fit.
+   - Apply once after fit.
+   - Remove generic deferred scroll restore from normal fit.
+
+6. Limit restore fallbacks.
+   - Keep fallback restore only for true remount/replay/reparent cases.
+   - Remove workspace-switch rAF/timeout restore loops once intent enforcement is
+     in place.
+
+7. Add focused tests.
+   - User scroll up sets `pinnedViewport`.
+   - Output while pinned preserves viewport.
+   - Output while following scrolls to bottom.
+   - Fit while pinned preserves viewport.
+   - Fit while following stays at bottom.
+   - Hidden-output replay while pinned does not repin.
+   - Workspace hide/show does not change intent.
+   - `onScroll` does not mutate intent.
+
+8. Add an E2E reproduction.
+   - Use the existing `scroll-primary` and `scroll-secondary` worktrees.
+   - Top pane in `scroll-primary` contains the TUI with enough scrollback.
+   - Scroll slightly above bottom, switch to `scroll-secondary`, then switch back.
+   - Assert the terminal remains within a small viewport tolerance and does not
+     visit top/bottom during the transition.
+
+## Acceptance Criteria
+
+- Switching away and back does not move a pinned TUI viewport.
+- No visible flash to top or bottom during activation.
+- Scrolling all the way to bottom re-enables follow-output and does not later
+  restore an older pinned position.
+- Hidden output in inactive workspaces does not change visible scroll position
+  until the user explicitly follows output or reaches bottom.
+- Alternate-screen TUIs do not receive extra restore/fill behavior that shifts
+  their cursor or scroll region.
+- The active pane remains responsive during heavy hidden-output catch-up.
+
+## Open Decisions
+
+- Whether Orca should patch private xterm bottom-scroll internals. The reference
+  pattern does this for strict ownership, but Orca should first try public API
+  enforcement at write/fit boundaries and only escalate if xterm continues to
+  auto-follow independently.
+- Whether scroll intent should be stored only by live `Terminal` instance or also
+  mirrored by leaf ID for remount fallback. The initial implementation should
+  use live instance state plus a leaf-keyed fallback for true replacement.
+- Whether alternate screen needs a separate intent record from normal screen.
+  The first version can use one record with `bufferType`; a separate normal vs
+  alternate record is justified only if testing shows mode switches overwrite
+  user intent.

+# Mobile Terminal Direct Input Default
+
+## Context
+
+Orca Mobile currently has two terminal input modes:
+
+- Buffered command input: a visible command text field sends its content with Enter.
+- Direct terminal input: a hidden capture field forwards keyboard bytes directly to the PTY.
+
+Buffered input is safer for composing a full shell command, but it is awkward for terminal-native
+flows: shells, TUIs, REPLs, editors, prompts, and remote SSH sessions all expect keystrokes to land
+immediately. The mobile terminal already supports direct input via a per-terminal toggle; this
+change makes direct input the default mode when a terminal is first seen on mobile.
+
+## Goals
+
+- Make first-seen mobile terminal tabs start in direct terminal input mode.
+- Keep the existing accessory toggle so users can switch an individual terminal back to buffered
+  command input.
+- Preserve that manual opt-out while the terminal remains open and the session tab list refreshes.
+- Keep behavior local to the mobile client. Do not add host/runtime state or desktop-visible
+  preferences for this small default change.
+- Avoid opening the keyboard automatically just because a terminal becomes active. Tapping the
+  terminal should focus the direct input capture, matching the current live-input interaction model.
+
+## Non-goals
+
+- Removing buffered command input.
+- Changing `terminal.send`, mobile subscription, or PTY sizing semantics.
+- Persisting a user preference across app launches.
+- Changing accessory keys, dictation, paste, terminal gesture input, or mouse-aware TUI routing.
+
+## Design
+
+The mobile session screen keeps `liveInputTerminalHandles`, a set of terminal handles whose input
+bar is in direct mode. Today the set starts empty, so every terminal defaults to the buffered command
+box.
+
+The new behavior adds a companion "default already applied" set. When the mobile client discovers
+terminal handles through session tab snapshots, `terminal.list`, or local terminal creation, it adds
+only never-before-defaulted handles to `liveInputTerminalHandles`. If a user toggles a handle back to
+buffered input, the handle stays in the defaulted set, so future tab refreshes do not flip it back to
+direct input.
+
+Handle cleanup uses `terminal.list` as the terminal lifetime signal. Session tab snapshots can lag
+locally created or recently closed terminal tabs, so they should default never-before-seen handles but
+should not prune the live/defaulted sets.
+
+This keeps the default one-shot per handle:
+
+1. New handle appears.
+2. Mobile marks it direct input by default.
+3. User can toggle it to buffered input.
+4. Snapshot/list refreshes preserve the user's choice.
+5. Worktree route reset clears the default tracking for the next session scope.
+
+## UI Behavior
+
+When a terminal is in direct mode, the existing live input bar remains:
+
+- The accessory direct-input icon is active.
+- The bar says keyboard input goes directly to the terminal.
+- Tapping the terminal focuses the hidden capture input.
+- The buffered command box remains available by pressing the same mode toggle.
+
+When a terminal is in buffered mode, the existing command field remains unchanged.
+
+## SSH And Provider Notes
+
+SSH sessions are a primary reason for this default. Direct mode avoids local composition assumptions
+and sends the same PTY bytes regardless of whether the shell is local or remote. The change does not
+touch source-control provider behavior.
+
+## Validation
+
+- Unit test the one-shot default merge:
+  - first-seen handles are enabled and marked defaulted;
+  - an already defaulted handle is not re-enabled after manual opt-out;
+  - newly discovered handles are still enabled.
+- Unit test stale-handle pruning from the terminal lifetime list.
+- Run focused mobile terminal tests.
+- Launch Orca Mobile in the iOS simulator, reach the session terminal screen, and capture a
+  screenshot showing the direct-input bar as the default terminal input surface.
