+## Remote Wire Compatibility

+Clients and remote Orca servers update independently, so mixed versions are the normal state. Before changing anything a paired client and host exchange — RPC params, stream frames, or the content either side publishes over them — follow [`docs/reference/remote-wire-compatibility.md`](./docs/reference/remote-wire-compatibility.md). A new optional field is safe; a new stream opcode must be capability-negotiated because decoders drop unknown opcodes silently; and changing what the host publishes reaches old clients even with no wire change.

 ## Git Binary Compatibility

 Orca runs the user's Git binary on native, WSL, and SSH hosts, which may all have different versions. Treat Git 2.25 as the core-workflow baseline and follow [`docs/reference/git-compatibility.md`](./docs/reference/git-compatibility.md).

+ * Naturalistic freeze repro — idle/reconnect recovery stories on large remotes.
+ *
+ * Unlike the bulk parallel-switch amplifier, this models:
+ *   1) agents streaming on remote while user is idle (backlog builds)
+ *   2) user returns and opens sessions one-by-one (or after reconnect refresh)
+ *
+ * Scenarios:
+ *   idle-backlog-open            — idle with flood, then human-paced sequential open
+ *   idle-backlog-reconnect-open  — same + wake-like metadata refresh storm, then open
+ *   restart-proxy                — idle, then orca open + status/list storm + open
+ *                                  (does NOT kill the desktop; proxies restore work)
+ *
+ * Usage:
+ *   ORCA_FREEZE_ENV=paired-remote ORCA_FREEZE_SCENARIO=idle-backlog-open \
+ *     node config/scripts/live-remote-realistic-freeze-repro.mjs

+# Mobile Relay UX — Investigation Findings & Fix Plan
+
+Scope: phone-side presentation/state-machine issues behind three reported symptoms on Android over
+the cloud relay. The relay protocol and server-side assignment are healthy; nothing here changes
+desktop or relay-server code. All file references are in `mobile/` of this worktree.
+
+## 1. Symptom → root-cause summary
+
+| # | Symptom | Root cause (verified) |
+|---|---------|----------------------|
+| S1 | Resume lands on an empty "Host" page, grey dot | Bare cross-stack `router.push` into a cold nested host navigator resolves to the host index route **without the `hostId` param**; every screen below then runs with `hostId: undefined` |
+| S2 | Tapping a healthy relay host shows grey 1–2s before green | Every screen focus funnels into the network-handoff recovery path, which **suspends the healthy relay session** (publishes `disconnected`) and re-dials; the re-dial is invisible because `migrateTo` binds new-session state only after authentication |
+| S3 | Relay-forced pairing looks dead ~5–10s | The pairing relay path has **no log sink** (only direct-path entries reach the "Pairing log"), and post-pairing the app dials the unreachable LAN endpoint for up to 12s before relay recovery is even eligible |
+
+## 2. Verified end-to-end causal chains
+
+### S1 — Resume dead-ends on the host index page
+
+1. Home renders the Resume card only once `hostStates[lastVisited.hostId] === 'connected'`
+   (`app/index.tsx:488`); over relay that is seconds after the host list paints, and the card
+   inserts **above** the Tasks card in the same footer (`app/index.tsx:733-780`) — a layout shift
+   under the thumb.
+2. Tap → bare `router.push(createMobileSessionHref(...))` (`app/index.tsx:740-746`) targeting
+   `/h/[hostId]/session/[worktreeId]`.
+3. With the `h` group cold (cold start, or host never visited this session), Expo Router resolves
+   the push to the host stack's **index route with no `hostId` param**. This exact failure mode is
+   documented twice in-repo ("cold Expo deep links resolve to index" —
+   `src/transport/host-edit-navigation.ts:52`, `src/tasks/mobile-task-navigation.ts:90`) and is the
+   root cause named by PR #12001.
+4. `app/h/_layout.tsx:64` reads `hostId` via `useGlobalSearchParams` → `undefined`.
+   `HostProtocolGate` gets `hostId: undefined`; `useHostClient(undefined)` returns
+   `state: 'disconnected'` (`src/transport/client-context.tsx:344`) → **grey dot**.
+5. The host index screen renders the fallback title `'Host'` (`app/h/[hostId]/index.tsx:821`), and
+   every fetch no-ops on `!client || connState !== 'connected'`
+   (`app/h/[hostId]/index.tsx:298,364,418,520`) → **empty list**. The Filter/Recent/Repo chips are
+   static toolbar UI, so the page looks "real" but dead.
+6. "Sometimes": a warm host stack resolves the same push correctly, so the bug is intermittent by
+   navigation history.
+
+Corrections to the preliminary sweep: the empty page is primarily the missing `hostId` param, not
+the connection-gated fetches or the cold 30s worktree cache (those matter only when landing *with*
+a valid `hostId`, e.g. the mistap-strand case). Also, the Resume target "validation" is weaker than
+it looks: `getCachedWorktrees` is seeded from the persisted home snapshot at hydration
+(`app/index.tsx:264-277`) and the 30s TTL is stamped at seed time (`src/cache/worktree-cache.ts:20`),
+so a worktree deleted while the phone was off still passes until a live `worktree.ps` overwrites it.
+
+**Fix**: PR #12001 ("open the Resume workspace through a mounted host stack") routes Resume through
+the same mount-then-replace mechanism Tasks uses, extracted to `src/navigation/host-stack-navigation.ts`.
+Reviewed and validated per Jinwoo; **merged to main as `7948e46db855`** after final validation
+(see §4, F0). Residual S1 items it does not cover: bare notification/accounts/deep-link pushes (F4),
+catalog validation + not-found bounce (F7), Resume-card layout shift (F8), gate unmount hazard (F9).
+
+### S2 — grey blink when focusing a healthy relay host
+
+1. Every focus of the host screen fires `notifyForeground()`
+   (`app/h/[hostId]/index.tsx:512-517`, deliberately empty deps).
+2. `openHostLogicalClient` wraps that into `endpointLifecycle.setForeground(true)`
+   (`src/transport/host-logical-client.ts:31-33`); the lifecycle forwards without dedupe
+   (`src/transport/mobile-endpoint-lifecycle.ts:62-64`).
+3. `MobileEndpointSupervisor.setForeground(true)` computes `wasForeground = true` and calls
+   `RelayReconnectController.handleForeground` (`src/transport/mobile-endpoint-supervisor.ts:115-119`).
+4. `handleForeground` with `wasForeground && state === 'connected'` **suspends the healthy session**
+   (`src/transport/mobile-relay-reconnect-controller.ts:53-60`). `suspendActiveRelay` early-returns
+   unless the active path is `'relay'` (`:77-84`) — which is why LAN hosts never blink.
+5. `suspendActiveSession` closes the physical session, disposes all subscriptions, and publishes
+   `'disconnected'` (`src/transport/stable-logical-rpc-client.ts:164-180`) → grey dot
+   (`src/components/StatusDot.tsx:11`), worktree queries blocked.
+6. `onRetry()` → `recoverRelay()` → `openRelay` + `migrateTo`. During the dial the logical state
+   **stays 'disconnected'**: `migrateTo` only binds the new session's state after
+   `waitForAuthenticated` resolves (`src/transport/stable-logical-rpc-client.ts:188,213`), and the
+   dialing session's own `connecting`/`handshaking` publishes (`src/transport/mobile-relay-rpc-session.ts:43,74`)
+   fire with no listeners attached. Grey persists the full 1–2s (happy path has no artificial
+   delays; any failure adds ≥250ms full-jitter backoff, `src/transport/mobile-relay-retry-delays.ts:3-5`).
+7. `migrateTo` completes → `'connected'` → green; subscriptions replay; gated fetches rerun.
+
+Second trigger for the same path: OS network-revival nudges call `notifyForeground()` on every live
+client (`src/transport/client-context.tsx:286-292`, `src/transport/connection-revival-triggers.ts`)
+— any Wi-Fi↔cellular transition or came-online event grey-blinks every connected relay host.
+
+Design context: the suspend-on-repeat-foreground is pinned by the supervisor test as the
+network-handoff half-open case (`src/transport/mobile-endpoint-supervisor.test.ts:~160-197`). The
+asymmetry is that **direct sockets probe instead of tearing down** — `notifyForeground` on a
+connected direct client runs an activity probe that detects a half-open socket in ≤8s
+(`src/transport/rpc-client.ts:1119-1124`) — while relay sessions have a no-op `notifyForeground`
+(`src/transport/mobile-relay-rpc-session.ts:106`) and the supervisor's only tool is
+suspend-then-redial. There is also an in-repo make-before-break precedent: lease rotation calls
+`recoverRelay(forceReplacement = true)` and migrates a **live** session with zero visible blink
+(`src/transport/mobile-endpoint-supervisor.ts:56-59,146,249`).
+
+Divergent mount defaults (secondary): home renders `hostStates[id] ?? 'connecting'` (amber,
+`app/index.tsx:707`) while `getState()`/`useHostClient` return `'disconnected'` (grey) for a
+missing store entry (`src/transport/client-context.tsx:221,344`) — so host screens flash grey
+during the async client acquire (Keychain read) that home never shows.
+
+### S3 — silent 5–10s relay-forced pairing
+
+Pairing phase:
+
+1. `pair-confirm.tsx` / `pair-scan.tsx` pass `connectOptions.onLog` into `startPreProfilePairing`
+   (`app/pair-confirm.tsx:91-99`, `app/pair-scan.tsx:135-143`).
+2. The coordinator threads it **only to the direct candidate**
+   (`src/transport/pre-profile-pairing-coordinator.ts:152-157`). The relay candidate
+   (`:161-187`) gets nothing: `connectMobileRelayForPairing` has no log parameter at all
+   (`src/transport/mobile-relay-physical-client.ts:22-30`), nor do the director resolution,
+   journal writes, or the recovery loop in `src/transport/pairing-relay-candidate.ts`.
+3. With LAN unreachable, the visible "Pairing log" shows only the direct dial stalling toward its
+   12s connect timeout while the relay path does the real work silently: cell WebSocket + E2EE
+   handshake + `pairing.provisionRelay` + `pairing.getEndpoints` + credential-bundle write
+   (`pre-profile-pairing-coordinator.ts:206-233`). The error copy even says "see log below for
+   where it stalled" (`app/pair-confirm.tsx:138`) — the log cannot show it.
+4. Un-logged waits in the relay recovery loop: each of up to 3 attempts wraps a 5s director
+   resolution (`src/transport/mobile-relay-invite-director.ts:16`) plus full-jitter sleeps capped
+   at 100/200/400ms (`src/transport/pairing-relay-candidate.ts:58-59,70-71`) — worst case ~15s of
+   silence. (Correction: the preliminary "~3×2s of backoff" was wrong; the sleeps are small, the
+   director resolves dominate.) The relay E2EE layer itself has **no timers**: a pairing relay
+   request is unbounded except the screen's 25s cap (`app/pair-confirm.tsx:27`).
+5. Pairing logs also never reach `connectionLogStore` (single producer:
+   `src/transport/client-context.tsx:132`), so the Connection Log screen shows nothing about a
+   pairing that just failed.
+
+Post-pairing phase:
+
+6. `pair-confirm` calls `closeHost(hostId)` then replaces to `/h/<id>`
+   (`app/pair-confirm.tsx:118-123`).
+7. The destination re-acquires a client asynchronously (grey `'disconnected'` default during the
+   Keychain read, `src/transport/client-context.tsx:221`), then dials the **LAN endpoint first**
+   (`src/transport/host-logical-client.ts:12`) — amber for up to `CONNECT_TIMEOUT_MS = 12s`
+   (`src/transport/rpc-client.ts:126`) on a black-holed LAN.
+8. Relay recovery cannot start earlier: `needsRecovery` treats `connecting`/`handshaking` as live
+   progress (`src/transport/mobile-relay-reconnect-controller.ts:73-75`), checked at supervisor
+   start and on every retry (`src/transport/mobile-endpoint-supervisor.ts:106,146`).
+9. When the direct dial finally fails, the relay dial runs invisibly (same `migrateTo` mechanism
+   as S2) → green. Worst case with a director resolution failure and grace-credential retry:
+   ~29–58s under the old session's labels.
+10. The "Orca Relay" path label only renders once `state === 'connected'`
+    (`src/components/MobileHostCard.tsx:23,47`) — the user learns the phone is using relay only
+    after the wait ends, and `classifyConnection` has no relay-aware branch
+    (`src/transport/connection-health.ts:45-100`).
+
+## 3. Anti-pattern sweep
+
+### (a) Uncoordinated deep pushes into `/h` from outside the host stack
+
+Coordinated today (mount-then-replace): host edit (`src/transport/host-edit-navigation.ts`) and
+Tasks (`src/tasks/mobile-task-navigation.ts`). Note host-edit's predicate is weaker — it checks the
+root route only and can fire its `replace` while the nested stack is still gated/unmounted; Tasks
+proves the nested stack exists (`mountedHostStack`, `mobile-task-navigation.ts:53-70`).
+
+Bare pushes remaining (host stack plausibly cold at each):
+
+| Call site | Target | Cold scenario |
+|---|---|---|
+| `app/_layout.tsx:127` via `src/notifications/notification-routing.ts:58,64` | `/h/<id>/session/<wt>` or `/h/<id>` | **Coldest path** — `getLastNotificationResponse()` after launch from a killed app, plus the warm listener |
+| `app/index.tsx:740-746` (Resume) | `/h/[hostId]/session/[worktreeId]` | Fixed by PR #12001 |
+| `app/index.tsx:835` (Account-usage card) | `/h/<id>/accounts` | Home is the root route |
+| `orca://` deep links (scheme in `app.json:9`, no linking config) | any `/h/...` | Default filesystem linking, zero coordination; `app/_layout.tsx:52-58` only intercepts pairing codes |
+| `app/h/[hostId]/history/[worktreeId].tsx:15`, `pr/[worktreeId].tsx:16` | redirect to source-control | A cold deep link to these hits the same cold-navigator resolution first |
+
+Shallow index-only pushes (`app/index.tsx:723,803`, onboarding/pair flows) don't need coordination.
+No `<Link>`, `navigationRef`, or `router.navigate` anywhere in `mobile/`.
+
+Related hazard: `HostProtocolGate` **unmounts the mounted HostStack mid-connect** for a first-visit
+host — stack mounts while `connecting`, is replaced by a spinner when `status.get` goes in flight
+(`statusPending` true only when connected: `src/transport/host-status-gates.ts:111`), then remounts
+(`src/components/HostProtocolGate.tsx:34-44`). A deep navigation that resolved into the first mount
+can be destroyed by the gate cycle.
+
+### (b) Surfaces that render grey 'disconnected' during expected transients
+
+Store defaults: every read API on the canonical store defaults to `'disconnected'` for a missing
+entry — `getState` (`src/transport/client-context.tsx:221`), `useHostClient` seed/re-seed/unbound
+fallback (`:343-345,377,393`). Exactly one call site defaults to amber instead: the home screen's
+`hostStates[id] ?? 'connecting'` (`app/index.tsx:707,903`), whose reconciliation effect also
+refuses to write `'disconnected'` for a never-tracked host (`:378-394`) — home already solved
+locally what every other surface gets wrong.
+
+The grey window is not one frame: `openEntry` awaits `loadHosts()` (a Keychain/SecureStore pass)
+**before** inserting the store entry (`client-context.tsx:87-161`, insert at `:153`), so a cold
+start or deep link into `/h/[hostId]` shows grey for the whole Keychain latency. The physical
+client is not the cause — it already reports `'connecting'` synchronously by the time `connect()`
+returns (`rpc-client.ts:302,967`). Additionally, `forceReconnect` deletes the entry then awaits the
+async reopen (`client-context.tsx:201-218`), so **every Retry button drives the UI grey before
+amber**.
+
+Surfaces that show grey / "disconnected" copy for a healthy host during these transients (all via
+`useHostClient`): host header dot (`app/h/[hostId]/index.tsx:819`); host toolbar + FAB disabled
+(`:850-860,941-1000,1063-1078,1209`); the workspace list body renders **nothing at all** for
+`disconnected` — `selectHostWorkspaceListState` falls through to `null`, not even a spinner
+(`src/worktree/host-workspace-list-state.ts:17-24`); tasks header dot + "Connect to a host" empty
+state (`app/h/[hostId]/tasks.tsx:8681,8661-8663`); session dot (no `verdict` prop at all,
+`session/[worktreeId].tsx:4434`) and the literal "Disconnected" chip (`:4246-4255`); native-chat
+composer lock (`src/session/MobileNativeChatView.tsx:427-432`); source-control / git-history /
+diff-review / file-explorer / agent-history "Waiting for desktop…" states; the connection-log
+screen prints the raw enum (`app/connection-log.tsx:113-117`); home's Resume/Accounts/Tasks/Quick
+Action gates all read `=== 'connected'`; voice settings goes fully inert
+(`app/voice-settings.tsx:50-55`). Counter-examples that behave well: home host card, the accounts
+screen ("Connecting to {host}…" + cached snapshot, `app/h/[hostId]/accounts.tsx:366-370`).
+
+Deliberate transients that publish `'disconnected'` while healthy work proceeds: relay suspend on
+focus/network nudges (S2); background suspend (`src/transport/mobile-endpoint-supervisor.ts:123` —
+correct per billing, but state stays grey through the entire foreground re-dial rather than
+flipping to `'connecting'`); post-migration cleanup (`:251-253`); `closeHost` during the
+pair-confirm handoff (`src/transport/client-context.tsx:83`); three open-failure paths
+(`:107,114,135`).
+
+Destructive companion pattern — state flips don't just recolor, they **wipe loaded data**:
+`host-status-gates.ts:32,100-112` wipes cached host capabilities on every disconnect;
+`tasks.tsx:2774-2800` resets the whole screen's hydration and force-closes ~15 sheets;
+`session/[worktreeId].tsx:2043,2432-2439,3713-3716` clears diff comments/capability flags/agent
+lists; the PR sidebar hides entirely (`src/session/use-mobile-pr-branch-context.ts:59-66` →
+`use-mobile-pr-sidebar-controller.ts:113-118`); git history blanks rows on the **reconnect** branch
+(`src/source-control/MobileGitHistoryList.tsx:63-68`); the repo cache survives disconnect but is
+wiped by the rejected in-flight call (`NewWorktreeModal.tsx:330-333`); the worktree cache is read
+only at mount/hostId change (`app/h/[hostId]/index.tsx:129,330`), never on reconnect, so a >30s
+entry means an empty remount.
+
+Same bug class in a second enum: `workspaceSshStatusLabel` defaults a `null` SSH status to
+"Disconnected" (`src/tasks/workspace-ssh-gate.ts:14-37`, rendered in `NewWorktreeModal.tsx:863`
+and `tasks.tsx:10970`).
+
+### (c) Invisible relay establishment phases
+
+- `connectMobileRelayRpcSession` (normal relay connects) has **no onLog** — the entire relay
+  session lifecycle emits nothing (`src/transport/mobile-relay-rpc-session.ts:30-39`); the
+  supervisor logs only coarse post-hoc lines (`mobile-endpoint-supervisor.ts:185-188,261`).
+- `migrateTo` structurally discards the dialing session's `connecting`/`handshaking` states
+  (`src/transport/stable-logical-rpc-client.ts:182-223,267-299`).
+- Direct→relay upgrade path has no sink at all (`src/transport/mobile-endpoint-lifecycle.ts:49-58`,
+  `mobile-relay-direct-upgrade-controller.ts:19`).
+- Pairing relay path fully silent (S3 above); pairing logs never reach `connectionLogStore`.
+- Path label ("Orca Relay") gated on `connected` (`src/components/MobileHostCard.tsx:47`);
+  `classifyConnection` collapses `connecting`/`handshaking`/`reconnecting` and has no relay branch.
+- Regression suite for connect-label stalls exists for the direct path only
+  (`src/transport/cellular-connecting-label-stall.test.ts`); no relay equivalent.
+
+## 4. Fix plan
+
+Ordered by felt-flakiness-removed per unit risk. All fixes are phone-local; none change the wire
+protocol, so every old/new phone × old/new desktop pairing keeps working unless noted.
+
+### F0 (S1, quick win) — land PR #12001 ✅ MERGED
+
+Squash-merged to main as `7948e46db855` (2026-08-04) after validation: CI fully green; drift check
+against current main clean (only overlap, #12575, touches different regions of `app/index.tsx` and
+auto-merges); full mobile suite (411 files, 3110 tests) passed on a local merge of main into the PR
+branch. The PR routes Resume through the shared mount-then-replace mechanism
+(`src/navigation/host-stack-navigation.ts`) and adds a source-guard test against reintroducing the
+bare push. This branch has since been fast-forwarded onto that merge, and F4 builds on the
+extracted module.
+Backward compat: navigation-only, none.
+Residuals tracked as F4/F7/F8/F9.
+
+### F1 (S2, quick win) — stop suspending a healthy relay on focus ✅ IMPLEMENTED (this branch)
+
+Approach: split the nudge reasons that today all funnel into `setForeground(true)`:
+
+- Screen-focus nudge (`app/h/[hostId]/index.tsx:515`): must not suspend. For the relay path, either
+  no-op (state changes already drive the UI) or run a cheap liveness probe (an RPC with a short
+  budget) and only enter recovery on failure — mirroring the direct path's activity probe.
+- Network-change / app-resume nudges: keep half-open protection, but **verify by replacement**
+  instead of break-before-make: call the existing `recoverRelay(forceReplacement = true)` path
+  (proven by lease rotation) so `migrateTo` swaps sessions with the dot staying green; only if the
+  replacement dial fails, fall back to `suspendActiveRelay` so a genuinely dead link stops lying
+  green and the retry loop re-arms (plain `recoverRelay` early-returns while the stale state is
+  still `'connected'`, so the fallback suspend is required for convergence).
+
+Files: `src/transport/mobile-relay-reconnect-controller.ts` (`handleForeground`),
+`src/transport/mobile-endpoint-supervisor.ts` (thread a nudge reason; failure-path suspend),
+`src/transport/mobile-endpoint-lifecycle.ts`, `src/transport/host-logical-client.ts` (reason-tagged
+`notifyForeground`), optionally `src/transport/rpc-client.ts` type for the reason parameter.
+Risk: PEER_DROPPED/LIMIT_EXCEEDED churn if replacement dials overlap — reuse the existing
+`shouldDefer` cooldown; billed duplicate socket for the overlap window (lease rotation already
+accepts this). Half-open regression risk is covered by the fallback suspend.
+Tests: split `mobile-endpoint-supervisor.test.ts:~160-197` into (focus nudge → no suspend, dot
+stays green) and (network handoff → replacement dial; failure → suspend + cooldown). Keep the
+background-suspend test unchanged.
+
+### F2 (S2/S3, quick win) — unify mount defaults to 'connecting' ✅ IMPLEMENTED (this branch)
+
+Approach: `getState(hostId)` returns `'connecting'` when the host is known (primed profile or
+pending open) and no entry exists yet; `'disconnected'` only for unknown/closed hosts. Aligns every
+host screen with home's `?? 'connecting'`. Two companion changes in the same class:
+- `forceReconnect` should notify `'connecting'` (or insert a placeholder entry) instead of leaving
+  the deleted-entry window grey (`src/transport/client-context.tsx:201-218`) — every Retry button
+  currently drives the UI grey before amber.
+- Optionally have `openEntry` insert a `'connecting'` placeholder before the Keychain read so the
+  cold-start gap (`client-context.tsx:87-153`) is amber too.
+
+**Required interaction fix**: `app/h/[hostId]/index.tsx:738-741` falls back to
+`lastKnownWorktrees` only for `disconnected | reconnecting | auth-failed`; `connecting`/
+`handshaking` fall through to the live (empty on fresh mount) array. Flipping the default without
+extending that predicate would silently disable the stale-list fallback and blank the list —
+extend it to every not-connected state (or key it on "no live fetch has succeeded this mount").
+Files: `src/transport/client-context.tsx` (`getState`, `useHostClient`, `forceReconnect`,
+`openEntry`), `app/h/[hostId]/index.tsx` (fallback predicate),
+`src/worktree/host-workspace-list-state.ts` (render a spinner for the not-connected states instead
+of `null`).
+Risk: a permanently unreachable host now shows amber briefly before the verdict system escalates —
+acceptable; `classifyConnection` already owns escalation. Audit the §3(b) "wipe" sites for any that
+key on `'disconnected'` specifically.
+Tests: `client-context.test.ts` known-vs-unknown host defaults + forceReconnect state sequence;
+host screen test for the stale-list fallback under `'connecting'`.
+
+### F3 (S3, quick win) — give the pairing relay path a log sink ✅ IMPLEMENTED (this branch)
+
+Approach: add an optional `onLog` to `connectMobileRelayForPairing`,
+`createRecoveringPairingRelayCandidate`, and `resolvePairingInviteThroughDirector`; thread
+`connectOptions.onLog` from the coordinator to the relay candidate; emit phase lines ("relay:
+resolving director…", "relay: cell connected", "relay: E2EE handshake…", "relay: authenticated",
+"relay: installing credential…"). Optionally also append pairing logs into `connectionLogStore`
+under the resolved host id so the Connection Log screen has a record post-pairing.
+Files: `src/transport/mobile-relay-physical-client.ts`, `pairing-relay-candidate.ts`,
+`mobile-relay-invite-director.ts`, `pre-profile-pairing-coordinator.ts`.
+Risk: none (additive, phone-local). Old desktops: unaffected — logging only.
+Tests: coordinator test asserting relay-path log entries arrive through `connectOptions.onLog`;
+extend `pairing-relay-candidate.test.ts` for per-attempt lines.
+
+### F4 (S1 class, quick win after F0) — coordinate the remaining bare deep pushes
+
+Approach: route notification taps (`app/_layout.tsx:127` + `src/notifications/notification-routing.ts`)
+and the Account-usage card (`app/index.tsx:835`) through `src/navigation/host-stack-navigation.ts`
+once #12001 lands; migrate host-edit onto the same stricter mechanism (#12001's own noted
+follow-up). `orca://` deep links can follow later via a route-level guard.
+Risk: notification cold-start ordering (push before root nav ready) — the mechanism already
+tolerates that by waiting for state commits.
+Tests: reuse the `host-stack-navigation.test.ts` harness for a notification-shaped target.
+
+### F5 (S2/S3, deeper) — make relay dials visible through `migrateTo`
+
+Approach: while the logical client is `suspended`/`'disconnected'`, have `migrateTo` forward the
+dialing session's state publishes (`connecting`/`handshaking`) to `publishState`, unbinding on
+success (normal bind takes over) or failure (restore `'disconnected'`). Guard: never downgrade a
+still-`'connected'` previous session (make-before-break migrations must stay green). Follow-on UI:
+show the path being dialed ("Connecting via Orca Relay…") by exposing the pending path, and let
+`MobileHostCard`/`classifyConnection` render it while not yet connected.
+Files: `src/transport/stable-logical-rpc-client.ts` (+ its test), `src/transport/connection-health.ts`,
+`src/components/MobileHostCard.tsx`, `src/transport/mobile-connection-path-label.ts`.
+Risk: state-ordering regressions in the pinned stable-client and connecting-label suites; keep the
+forwarding strictly gated on suspended/disconnected.
+Tests: add a relay-path analog of `cellular-connecting-label-stall.test.ts`; stable-client cases:
+forwarded states during suspended dial, no forwarding during live-session replacement, failure
+restores `'disconnected'`.
+
+### F6 (S3, deeper) — happy-eyeballs relay start post-pairing
+
+Approach: when a relay credential bundle exists and the direct dial has not authenticated within a
+short grace (2–3s), start the relay dial in parallel instead of waiting for the 12s direct failure;
+first authenticated path wins via the existing `migrateTo`/hysteresis machinery. Scope initially to
+the first connect after pairing (or hosts whose last success was relay) to avoid pointless relay
+sockets on healthy LANs.
+Files: `src/transport/mobile-endpoint-supervisor.ts` (start/needsRecovery gating), possibly a
+phone-local `HostProfile` hint field (no protocol impact; old desktops never present `relay`, so
+the path is naturally guarded).
+Risk: racing direct is exactly what `needsRecovery`'s design avoids — needs the mutex
+(`operationInFlight`) audit and dwell/hysteresis respect; billed relay data on LANs if scoped too
+broadly.
+Tests: supervisor fake-timer cases: black-holed LAN converges in ~3-5s; healthy LAN never opens a
+relay socket; relay loser closed after direct wins.
+
+### F7 (S1, deeper) — catalog-validate resume targets + not-found bounce
+
+Approach: (1) on Resume tap with the host connected, validate the target against the freshest
+`worktree.ps` result (not the snapshot-seeded cache); if absent, open the host index instead.
+(2) In the session screen, once connected and the catalog is known, bounce unknown `worktreeId`s
+(exempting `folder:` and floating-workspace sentinels, `app/h/[hostId]/session/[worktreeId].tsx:852-854`)
+to the host index with a notice. (3) Use the validating reader in
+`src/worktree/last-visited-worktree-repo.ts` on home instead of the raw `JSON.parse`
+(`app/index.tsx:315-322`), and import the storage-key constant at both literal call sites.
+Risk: false bounces during slow catalog loads — only bounce on a *confirmed* fresh catalog miss.
+Tests: repo tests for the validating reader on home; session-screen bounce cases incl. sentinel
+exemptions.
+
+### F8 (S1 aggravator, cheap) — stop the Resume/Tasks layout shift
+
+Approach: reserve the Resume card's slot (fixed-height placeholder or render-below-Tasks) so its
+late arrival cannot move the Tasks card under the thumb; alternatively render the card immediately
+from the snapshot in a disabled state until the host connects.
+Files: `app/index.tsx` footer.
+Risk: none.
+Tests: render test asserting footer order/height stability across `resumeWorktree` arrival.
+
+### F9 (S1 class, deeper) — HostProtocolGate should not unmount a mounted stack
+
+Approach: once the HostStack has mounted for a host, keep it mounted and overlay the pending
+spinner instead of replacing children, preserving in-flight nested navigation; keep the hard
+replace only for the `blocked` verdict.
+Files: `src/components/HostProtocolGate.tsx`.
+Risk: the gate exists so child routes don't call too-new RPCs while compatibility is unknown — an
+overlay must still block interaction until resolved; verify child mount effects don't fire gated
+RPCs pre-verdict before choosing overlay vs. current behavior.
+Tests: gate test asserting no unmount across `statusPending` for an already-mounted host.
+
+### F10 (S2 class, deeper) — stop wiping loaded data on transient state flips
+
+Approach: audit the §3(b) destructive-clear sites and make each preserve data across a
+not-`'connected'` blip, clearing only on host change or explicit sign-out. Top offenders by felt
+impact: git history blanking rows on the reconnect branch
+(`src/source-control/MobileGitHistoryList.tsx:63-68` — refetch without `setRows(null)`); the repo
+cache wiped by the rejected in-flight call (`NewWorktreeModal.tsx:330-333` — keep last-good on
+error); the diff-review "ready-state preserved" branch that is dead code because it sits after the
+early return (`src/session/use-mobile-diff-review-controller.ts:85-89`); host capability wipe
+(`src/transport/host-status-gates.ts:32`); the tasks-screen full re-hydration
+(`app/h/[hostId]/tasks.tsx:2774-2800`); worktree-cache re-read on reconnect, not only at mount
+(`app/h/[hostId]/index.tsx:129,330`).
+Risk: showing stale data as if live — pair each preservation with the existing staleness verdicts
+rather than inventing new indicators. The in-repo reference pattern is
+`src/worktree/home-worktree-info.ts:27-47`: counts older than a 10min TTL render as
+"Last known: N worktrees" instead of being dropped, and `markHomeWorktreeCatalogUnavailable`
+preserves proven counts across a failed refresh, flagging only `staleCounts`.
+Tests: per-surface "data survives disconnect→reconnect" cases; F1 largely removes the *trigger*
+(suspend blips), so this is hardening, not the primary fix.
+
+## 5. Backward compatibility (old/new phone × old/new desktop)
+
+- Every fix above is phone-app-local; no RPC methods, close codes, credential formats, or pairing
+  steps change. Old phones against any desktop are untouched (they don't have the code).
+- New phone + old desktop without relay support: `host.relay` is absent → F1/F5/F6 relay paths
+  never activate; pairing keeps the existing `method_not_found` downgrade
+  (`src/transport/pre-profile-pairing-coordinator.ts:210-217`); F3 logging is inert (no relay
+  candidate is created).
+- New phone + old desktop with relay: all paths use existing RPCs (`status.get`,
+  `pairing.provisionRelay`, resume confirm) — no new calls introduced. F1's replacement dial reuses
+  the same resume-credential flow lease rotation already exercises against production desktops.
+- F6's profile hint (if added) is a phone-local persisted field; absent values behave as today.

+# Remote wire compatibility
+
+Orca's remote-server feature pairs a desktop client to a remote Orca runtime, and
+users update the two independently. **Mixed versions are the normal state**, not an
+edge case. This page is the contract for changing anything a paired client and host
+exchange: the runtime RPC envelope, the terminal binary stream, and the content
+either side publishes over them.
+
+`src/shared/protocol-version.ts` says when to bump `RUNTIME_PROTOCOL_VERSION`. This
+page covers the changes that do _not_ bump it and are therefore easy to get wrong.
+
+## Rule 1 — a new optional JSON field on an existing frame is safe
+
+Every JSON payload is parsed with a decoder that ignores unknown keys (zod `.strip()`
+on RPC params, `JSON.parse` on stream frames). An older peer that has never heard of
+the field simply does not read it.
+
+Safe:
+
+```ts
+// host adds a field; older clients ignore it
+encodeTerminalStreamJson({ kind, cols, rows, hiddenOutputReason })
+```
+
+**The field is safe only for as long as every reader treats it as optional.** The
+moment a newer client _requires_ it, that client is broken against every host that
+predates the field — which is the same defect as removing a field, just discovered
+later. If new behavior depends on the field being present, that is Rule 2: negotiate
+it, or make the reader fall back.
+
+## Rule 2 — a new stream opcode is NOT safe; negotiate it
+
+`decodeTerminalStreamFrame` returns `null` for an opcode it does not know, and
+`runtime-rpc.ts` drops that frame without an error:
+
+```ts
+const frame = decodeTerminalStreamFrame(bytes)
+if (!frame) {
+  return // silently dropped — the sender never learns
+}
+```
+
+So a new opcode sent to an older peer does not fail loudly. It vanishes, and the
+feature behind it appears to hang. Input sent under a new opcode is swallowed.
+
+A new opcode must be announced in the subscribe handshake and sent only after the
+peer confirms it. The existing pattern is `SetOutputPaused` (opcode 16):
+
+- the client advertises support in the `Subscribe` frame's `capabilities`;
+- the host echoes `capabilities: { outputPause: 1 }` on the `subscribed` event;
+- the client sends opcode 16 only after that echo (`stream.supportsOutputPause`);
+- the host only acts on opcode 16 when it negotiated it (`stream.supportsOutputPause`).
+
+Reuse an existing opcode with a new optional payload field (Rule 1) whenever that
+expresses the change; reach for a new opcode only when framing genuinely differs.
+
+Opcode numbers are permanent. See the `Ack = 13` and `ClaimViewport = 14` comments
+in `src/shared/terminal-stream-protocol.ts` for why a shipped number cannot be
+reused even if the feature behind it is removed.
+
+## Rule 3 — changing what the host publishes breaks old clients with no wire change
+
+The frame shape can be untouched and the skew still real, because clients react to
+frame _content_. PR #12641 is the worked example: the host stopped synthesizing a
+finished agent status, and clients running older code saw different content in an
+identical frame.
+
+Treat these as wire changes even though nothing in the codec moves:
+
+- a field the host stops populating (an old client reading it now sees `undefined`);
+- a value whose meaning, units, or nullability changes;
+- content the host stops synthesizing, trims, or starts deriving from a new source;
+- a frame the host stops sending, or starts sending, on an existing path.
+
+If old clients cannot interpret the new projection correctly, gate it behind a
+runtime capability the same way Rule 2 gates an opcode.
+
+## Enforcement
+
+`tests/e2e/cross-version-wire/cross-version-terminal-wire.unit.test.ts` runs the real
+host RPC methods and the real renderer multiplexer from two builds against each
+other — current working tree against the newest release tag, in both skew
+directions — over one scripted terminal journey (subscribe, input, hide/reveal
+snapshot, drop, reconnect).
+
+Run it with:
+
+```bash
+pnpm exec vitest run --config config/vitest.config.ts tests/e2e/cross-version-wire/cross-version-terminal-wire.unit.test.ts
+```
+
+It fails when a frame is refused by the receiving build's decoder (Rule 2), when the
+observed frame sequence changes (Rule 3), or when published snapshot content or
+negotiated capabilities differ from the contract. Adding an optional field keeps it
+green (Rule 1); making a client depend on that field turns the new-client/old-host
+pairing red.
+
+The harness covers the terminal stream only. It does **not** cover the session-tab
+sync channel, agent-session publications, file or Git RPCs, mobile/E2EE framing, or
+the relay transport. A change on those paths still needs its own reasoning against
+the three rules above.

+# Windows setup-runner shell
+
+On native Windows, Orca writes the `orca.yaml` setup script (and the issue command) to a generated
+runner file and types a launch command into a terminal. The runner is a **`.cmd` batch file by
+default**, exactly as it has been since setup hooks shipped.
+
+A script opts into bash by starting with a `#!` interpreter line:
+
+```yaml
+scripts:
+  setup: |
+    #!/usr/bin/env bash
+    [ -f .env ] || cp .env.example .env
+    pnpm install
+```
+
+Without that line the script keeps running under `cmd.exe`:
+
+```yaml
+scripts:
+  setup: |
+    copy .env.example .env
+    xcopy /E assets dist
+```
+
+## Why the script declares it, not the terminal preference
+
+`terminalWindowsShell` says which shell *interactive terminals* open in. It says nothing about the
+language a project's setup script is written in. Deriving the runner from it had two consequences:
+
+- Windows users with batch-syntax setup scripts silently switched to bash on upgrade, so `copy`,
+  `xcopy`, `set VAR=value`, and `if errorlevel 1` stopped working.
+- Two people on the same repo got different interpreters for the same `orca.yaml`, so no project
+  could write a setup script that worked for all of its Windows contributors.
+
+A `#!` line is per-project, explicit, and identical for everyone who checks the repo out.
+
+The same rule applies to the per-user setup command in **Settings → repository hooks**
+(`repo.hookSettings.scripts.setup`): it is merged into the same script that reaches the runner, so a
+POSIX one-liner stored there needs its own `#!` line to run under bash on Windows.
+
+## What the `#!` line does and does not select
+
+The generated runner is always executed by bash (`bash <runner>`; Git Bash on native Windows), on
+every platform. The `#!` line therefore does two things:
+
+- It declares the script is written for a POSIX shell, which is what selects the bash runner.
+- Its option flags are replayed with `set`, so `#!/usr/bin/env -S bash -euo pipefail` really does
+  get `pipefail`. Without that replay the flags would be silently dropped, because `bash <runner>`
+  never parses the interpreter line. Only the flags `set` itself accepts
+  (`[--abefhkmnptuvxBCHP] [-o option]`) are replayed; invocation-only ones such as `-l` are
+  dropped, because `set -l` exits 2 and would abort the runner before its first line.
+
+The interpreter name itself is not honored beyond "is this a POSIX shell": `#!/bin/sh` and
+`#!/bin/zsh` scripts run under bash, exactly as they already did on macOS and Linux.
+
+## Requirements for the bash runner
+
+A `#!` line only takes effect when Orca can actually launch bash from the configured terminal — the
+terminal shell must resolve to Git Bash (`resolveWindowsGitBashShellPath`). The generated runner
+uses MSYS `/c/...` paths, which Cygwin and the WSL shim do not accept, and the launch command is
+typed into whatever shell the terminal opened with.
+
+When bash is not available (a PowerShell/cmd terminal, or an SSH-to-Windows host, which always uses
+the remote's `.cmd` runner) the `#!` script is **not** executed under cmd. The generated `.cmd`
+runner prints why and exits 1, because running the interpreter-agnostic prefix of a bash script
+(`pnpm install`, `git submodule update`) and only failing at the first bash-only line leaves a
+half-set-up worktree that looks finished.
+
+## Launching a `.cmd` runner from a Git Bash terminal
+
+The runner format and the shell that types the launch command are independent: a Git Bash terminal
+with a batch-syntax setup script gets a `.cmd` runner launched from a bash pane. `cmd.exe /c
+"C:\..."` cannot be used there — MSYS rewrites the bare `/c` switch into a drive path, so cmd opens
+interactively and the runner never executes (issue #6896). Those launches reuse the PowerShell
+`ProcessStartInfo` launcher (`buildWindowsCmdRunnerDelayedLaunchCommand`), which carries the switch
+and the runner path outside the command line. `WorktreeSetupLaunch.shell` therefore describes the
+launching pane; the runner file's `.cmd`/`.sh` extension describes the format.
+
+The `wait-for-setup` gate follows the same split. The pane types the gate and already quoted the
+agent startup command for itself, so a `.cmd` runner launched from a Git Bash pane still gets the
+bash gate — PowerShell's `Invoke-Expression` cannot parse POSIX `'\''` escaping. The gate wraps the
+same `ProcessStartInfo` launcher, so the batch runner is never handed to bash.
+
+WSL worktrees and non-Windows platforms are unaffected: they always use the bash runner. SSH hosts
+choose their runner from the remote path format, never from local Windows preferences.
