web-terminal/android/PROGRESS_ANDROID.md

Android Client — Progress (this-session working log)

Why this file exists (temporary): docs/PROGRESS_LOG.md (the canonical cross-session memory) was being concurrently edited by another live session (the tunnel-automation workstream on branch feat/tunnel-automation) while this Android work ran on the SAME working tree. To avoid a read-modify-write clobber of that session's log, the Android orchestrator records progress here instead. FOLD THESE ENTRIES INTO docs/PROGRESS_LOG.md once the concurrent session is done (they belong under the 🤖 ANDROID CLIENT section).

Git status note: nothing below is committed. The Android lane (android/**, src/push/fcm.ts, test/push-fcm.test.ts, src/server.ts FCM wiring, package.json google-auth-library) is file-disjoint from the tunnel work, but the shared .git/index means no git add -A — commit the Android lane by explicit path once branch strategy is settled.

Plan: ../docs/ANDROID_CLIENT_PLAN.md. 36 tasks, waves AW0–AW6. Prior state (commit 4ea8f78/4fe1981): AW0 + AW1 pure-Kotlin foundation (218 tests) + Android SDK/AGP 9.2.1 toolchain proven.

[x] Wave R1 — A7 + A14 + A33 (DONE, orchestrator-verified 2026-07-08)

One implementation Workflow (3 TDD builders in parallel) → 6-agent adversarial cross-review (2 independent lenses/task) → fix Workflow (must-fixes + regression tests) → adversarial re-verify → orchestrator independent unified gate (not just agent self-report).

Unified verification (measured):

• cd android && ./gradlew test → BUILD SUCCESSFUL, 250 tests, 0 failures (wire-protocol 47 / session-core 75 / api-client 69 / client-tls 27 / test-support 15 / transport-okhttp 17).
• npx vitest run test/ → 54 files, 1533 tests, 0 failures (incl. new test/push-fcm.test.ts 60 tests; no regression of the existing server suite).
• npm run typecheck (tsc main + web) → clean.

[x] A7 :transport-okhttp — OkHttp WS + REST transport (pure JVM; MockWebServer-tested)

• Files: transport-okhttp/src/main/.../transport/{OkHttpClientFactory, OkHttpTermTransport, OkHttpWebSocketConnection, OkHttpHttpTransport}.kt + 3 test files. Implements frozen TermTransport/PingableTermTransport/HttpTransport verbatim (contracts unmodified).
• WS: connect() stamps Origin = endpoint.originHeader on the upgrade (CSWSH; asserted byte-equal); frames = channelFlow draining an unlimited listener mailbox — clean close → normal completion, onFailure → error (distinguishable); send→webSocket.send, close→close(1000) (detach, never kill). REST: non-2xx RETURNED, transport-failure THROWN, headers verbatim (no self-added Origin). Shared OkHttpClient .cache(null) (§8) + default system trust; mTLS via a LOCAL ClientIdentityProvider fun-interface seam (module depends only on :wire-protocol, no :client-tls edge).
• Cross-review fixes (regression-tested): (1) HIGH — handshake socket leak on mid-dial cancel: openConnection now tears down the just-created WS on any throwable (incl. CancellationException) via an idempotent cancel() (webSocket.cancel()+finish(null)) before rethrowing — proven red→green by revert. (2) HIGH — the redundant transport-level 16 MiB frame cap (TransportFrameTooLargeException) was deleted: it was unreachable from :session-core (which may depend only on :wire-protocol), and SessionEngine already self-measures frames and emits REPLAY_TOO_LARGE — the single authoritative classifier. (3) MEDIUM — pump rethrows CancellationException (defensive; kept as a contract lock).

[x] A14 SessionEngine — pure lifecycle state machine (:session-core, runTest virtual time)

• Files: session-core/src/main/.../session/SessionEngine.kt + SessionEngineTest.kt (15 tests). Composes ReconnectMachine/PingScheduler/GateTracker/AwayDigest over an injected TermTransport + dispatcher/TimeSource; NO OkHttp/Android imports.
• Verified: attach-first ordering, adopt-server-id, connect-now-on-foreground, close≠kill, oversized-replay→terminal REPLAY_TOO_LARGE, gate-decision epoch drop, backoff ladder 1→2→4→8→16→30, ping 25s/2-miss — all under virtual time via the fakes.
• Cross-review fixes (regression-tested): (1) HIGH (found independently by BOTH reviewers) — close() during the dial/attach window failed to detach the freshly-opened connection: engine now re-checks the closed flag after dial and after attach, closing + returning terminal with no further emits (2 new tests: close-during-dial, close-during-attach). (4) MEDIUM — gate double-send: decideGate() now locally retires the held gate after a successful send so a second same-epoch tap is dropped (new test). (2) MEDIUM — started flip moved onto the confined dispatcher (invariant #4). (3) MEDIUM — suspend-call runCatching replaced with cancel-rethrowing ignoringNonCancel.
• KNOWN follow-up routed to A15 (AW2): the engine does not close its live WS when its scope is cancelled (only on explicit close()). Intended teardown is explicit engine.close() (per §6.6), so the RetainedSessionHolder MUST call engine.close() before cancelling the engine scope; additionally consider a finally-close in the engine for defense-in-depth. Non-blocking for R1 (server PTY survives either way; only affects prompt-vs-TCP-timeout detach).

[x] A33 server FCM — the ONE additive server change (§4.5)

• Files: NEW src/push/fcm.ts (NotifyService impl behind a seam) + POST/DELETE /push/fcm-token route + initFcm/normalizeFcmToken wiring in src/server.ts (combined via combineNotifyServices beside web-push/APNs — zero new event paths) + FCM_* env (all-or-disabled) + test/push-fcm.test.ts (60 tests). Added google-auth-library@^10 to package.json deps (R7 decision).
• Data-only high-priority messages; payload minimized to sessionId/cls/token (no notification block, no cwd/command); loose FCM-token validator; token/key never logged; disabled cleanly when FCM_* incomplete.
• Cross-review fix (regression-tested): HIGH — removed validateStatus:()=>true, which had silently defeated google-auth-library's built-in 401/403 refresh-and-retry (the whole reason R7 chose the lib). Now wraps client.request in try/catch, reading {status,body} from GaxiosError.response; a 401 goes through the lib's refresh before surfacing; a no-response transport error is a send failure (token never falsely pruned). 3 new tests (401→refresh→200, 404/UNREGISTERED→prune, no-response→keep).

Not run here (deferred per plan §7): instrumented/device tests (no emulator installed) and the S2 FCM real-handset delivery spike (needs ≥2 physical devices under Doze/OEM battery managers).

[~] Wave R2 — A13 (done) · A11 + A12 (building) · S1 → moved to head of AW3

[x] A13 :app Compose baseline (DONE, orchestrator-verified 2026-07-08)

First real full Android app module — establishes the UI-stack version matrix every later Android task reuses. Workflow: TDD builder → kotlin + design cross-review.

• Files: app/build.gradle.kts, AndroidManifest.xml, WebTermApp.kt (@HiltAndroidApp), MainActivity.kt (@AndroidEntryPoint), di/AppModule.kt (minimal Hilt), designsystem/{DesignSpec, Tokens,Typography,Theme,Primitives}.kt, res/{values,xml}/*, DesignSpecTest.kt (5 JVM tests).
• Version matrix PROVEN (:app:assembleDebug → 32.7 MB APK, :app:testDebugUnitTest green): AGP 9.2.1 · Kotlin 2.3.21 · compose-compiler plugin 2.3.21 · Compose BOM 2025.11.01 (material3 1.4.0, ui 1.9.5, material3.adaptive 1.2.0) · Hilt 2.60.1 via KSP 2.3.9 · compileSdk 36 (installed platforms;android-36; SDK-37 unavailable — cmdline-tools too old), minSdk 29, targetSdk 35. Design system mirrors iOS DS 1:1 (amber-gold #E3A64A/#C9892F, semantic status colors, 8pt scale, tabular mono numerals, dark-first, fixed terminal-canvas #100F0D/#ECE9E3/gold).
• Cross-review fix (orchestrator applied + re-verified assemble green): both reviewers flagged the primitives (StatusBadge/TelemetryChip/WebTermCard) hardcoding WebTermColors.dark.* → would render wrong in light theme. Routed through MaterialTheme.colorScheme.{onSurfaceVariant, surfaceVariant,outline} (Theme.kt already maps those). Also fixed preview .dp literals → Spacing.*. Docs synced: android/README.md + settings.gradle.kts recipe + [[android-build-env]] memory now say compileSdk 36 / android-36.
• Deferred (per §7): instrumented/Compose-UI tests (no emulator). Follow-up for AW3: add a Motion.gated() helper (reduce-motion) to Tokens.kt when the first animation lands (LocalReduceMotion
  • DesignSpec.MOTION_* already present); register a ContentObserver on ANIMATOR_DURATION_SCALE then.

[x] A11 :client-tls-android — ClientTLS framework half (DONE, orchestrator-verified)

Catalog pre-staged (tink 1.15.0, datastore-preferences 1.1.1, androidx-test); enabled in settings. Build workflow → security+kotlin cross-review → fix workflow → adversarial security re-verify → orchestrator applied 3 more fixes the re-verify caught + independent compile gate.

• Files: client-tls-android/src/main/.../tlsandroid/{AndroidKeyStoreImporter, TinkCertStore(+CertStore iface), ReReadingX509KeyManager, IdentityRepository(+ClientSslMaterial), StoredIdentityMetadata}.kt
  • androidTest {Fixtures, AndroidKeyStoreImporterTest, IdentityRepositoryTest}.kt.
• ONE key home = AndroidKeyStore (non-exportable, per-handshake re-reading X509KeyManager); Tink AEAD encrypts ONLY the cert-chain+metadata blob; NO .p12/passphrase persisted; validate-before-persist; connectionPool.evictAll() on rotate/remove. Exposes IdentityRepository/ClientSslMaterial as the seam A15 bridges to :transport-okhttp's ClientIdentityProvider (NO :transport-okhttp dep).
• Security must-fix (rotation safety) — resolved via single-commit + adversarial follow-through: the re-verify caught the fixer's first attempt still lost the prior identity. Final design: ping-pong staging slot → one atomic durable SharedPreferences.commit() live-pointer flip (StoredIdentityMetadata.keyStoreAlias). Any failure before the flip → prior identity fully live; after → new identity fully live; stores never diverge. Orchestrator then fixed 3 residual bugs the security re-verify empirically proved: (1 HIGH) currentLive() used liveOverride?.value ?: initialIdentity which collapsed Box(null) (explicitly removed) into the stale cached identity → a removed cert stayed "live" and could be presented with a dangling key; now resolves via Box presence. (3) TinkCertStore.save()/clear() switched apply()→commit() (durable + throws on failure) so a crash-window can't leave the pointer naming a just-deleted key (both-identities-lost). (2) widened staging-key cleanup to cover the key-readback/encode steps. Added instrumented regression remove_afterStartupTouch_reportsNoIdentity_notStaleCached.
• Verified (orchestrator): ./gradlew :client-tls-android:assembleDebug :client-tls-android:compileDebugAndroidTestKotlin → BUILD SUCCESSFUL (main + instrumented compile). All AndroidKeyStore/Tink tests run on device (§7).

[x] A12 :host-registry — Host/HostStore + DataStore + LastSessionStore (DONE, both reviewers approved)

• Files: host-registry/src/main/.../hostregistry/{Host, HostStore(+immutable transforms), InMemoryHostStore, DataStoreHostStore, LastSessionStore, DataStoreLastSessionStore, HostCodec}.kt
  • tests (JVM unit: HostStoreTransforms/InMemoryHostStore/HostCodec/InMemoryLastSessionStore) + androidTest.
• Immutable HostStore (upsert/remove return new lists, position-preserved, unknown-id no-op); DataStore read-modify-write; HostEndpoint re-validated on load; LastSessionStore set-on-adopted / clear-on-exited. Orchestrator fix: DataStoreLastSessionStore now guards the persisted id with the frozen v4 Validation.isValidSessionId (was UUID.fromString format-only).
• Verified (orchestrator): ./gradlew :host-registry:assembleDebug :host-registry:testDebugUnitTest → BUILD SUCCESSFUL, 17 JVM unit tests green; DataStore-backed tests are androidTest (device QA).

S1 renderer spike — relocated to the head of AW3 (it gates A16, the XL renderer task).

Wave R2 complete. Android modules now: 6 pure-JVM (250 tests) + :app + :host-registry + :client-tls-android (framework, assemble+unit-verified here; instrumented deferred to device QA).

---

[x] Wave AW2 — A15 :app wiring + DI FREEZE (DONE, orchestrator-verified 2026-07-09)

The convergence/contract task that gates all of AW4. Build → arch+coroutine cross-review (BOTH blocked) → fix (6 must-fixes) → arch+coroutine re-verify (caught 1 more real bug) → residual fix → orchestrator added the final test lock + independent gate. ./gradlew :app:assembleDebug :app:testDebugUnitTest :session-core:test all green (EventBus 6 tests, RetainedSessionHolder 4, DesignSpec 5, SessionEngine 15).

• Files: app/src/main/.../wiring/{EventBus, TerminalSessionController, RetainedSessionHolder, AppEnvironment, ColdStartPolicy, ApiClientFactory, SessionEngineFactory}.kt + di/{NetworkModule, TlsModule, StorageModule, SessionModule}.kt (replaced A13's placeholder AppModule) + tests.
• Frozen contracts (AW4 depends on these): per-session EventBus (NOT @Singleton) with two typed sub-streams outputBytes(): Flow<ByteArray> (Output-only, UTF-8 decode off-Main via flowOn) + controlEvents(): Flow<SessionEvent> (non-Output); TerminalSessionController (start() decoupled from bind(), eager mailbox registration); RetainedSessionHolder (@HiltViewModel, config-survival, single-session-for-life BoundKey guard, close-join-before-cancel teardown); AppEnvironment.warmUp() (off-Main first identity touch); ColdStartPolicy; factories for per-host ApiClient + per-session SessionEngine. mTLS bridge: A11 IdentityRepository → A7 ClientIdentityProvider → ONE shared OkHttpClient (.cache(null), WS+REST) — construction cycle broken via a shared ConnectionPool.
• Coordination change (authorized): SessionEngine.close() now returns its Job so teardown can join() the clean detach BEFORE cancelling the confinement scope (structural close-before-cancel).
• Cross-review caught + fixed: (HIGH) EventBus was @Singleton → cross-session event bleed → now per-session; (HIGH) bind()-started-engine-before-UI-subscribe → lost attached+replay → decoupled start() + eager registration; (HIGH) eager DI did AndroidKeyStore/Tink I/O on Main → dagger.Lazy + warmUp() on IO; (HIGH, re-verify) register()'s finally-close made the reused controller's output/ events flows DEAD after one config-change (blank terminal on rotation) → mailbox now lives for the session (receiveAsFlow consume=false), released only by EventBus.close() at teardown; + typed sub-streams, structural close, bind mis-route guard, @Volatile started. R10 (per-consumer UNLIMITED channels: slow consumer neither stalls nor drops) unit-tested; confinement invariant #4 intact.

[~] Wave AW3 — A16 :terminal-view DONE · A17 KeyBar + A18 ThumbnailPipeline building

[x] S1 + A16 :terminal-view (XL) — the renderer, DONE + orchestrator-verified 2026-07-09

S1 gate PASSED headless (no device): a Termux TerminalEmulator (no JNI/subprocess) fed canned WS bytes renders into a readable TerminalBuffer ("hello", cursorCol 5); DSR reply routes out via TerminalOutput.write→engineSend; DECCKM ESC[?1h flips to ESC OA. Termux resolved via JitPack com.github.termux.termux-app:{terminal-view,terminal-emulator}:v0.118.0 (only transitive dep androidx.annotation; no guava → R2 shim unneeded; Apache-2.0 scope held — never termux-shared/app). JitPack repo + coordinate added to settings/catalog; :terminal-view enabled.

• Files: terminal-view/src/main/.../terminalview/{RemoteTerminalSession, RemoteTerminalView, TerminalGridMath, NoOpTerminalSessionClient, LinkPolicy}.kt + 5 test suites (17 unit tests).
• RemoteTerminalSession = the FORK (no subprocess): a single confined-writer via an ordered Channel<TerminalCommand> (Feed/Resize/Bind/Unbind); append chunked 4 KiB + yield(); onScreenUpdated posted to an injected main dispatcher. pendingOutput queued-then-flushed in order (ESC[0m preserved). Resize math extracted as pure TerminalGridMath (R5), JVM-tested. Titles pass RAW (no :session-core edge — :app wires TitleSanitizer); OSC-52 declined; http/https LinkPolicy.
• Sound deviation (§6.1): at v0.118.0 Termux TerminalView/TerminalSession are final → RemoteTerminalView is a COMPOSITION wrapper binding the forked emulator via the public mEmulator field (rendering stays 100% stock). Documented.
• Cross-review (correctness approved; threading blocked→fixed): HIGH — bind published mEmulator to the renderer SYNC before the pendingOutput flush → bind-time UI-read-vs-confined-append race; fixed by routing the publish through the Bind command (flush on confined thread, THEN post publish+onScreenUpdated to Main together; test captures buffer state AT publish). MEDIUM — confined command loop now try/catches (rethrows Cancellation) so a hostile escape byte can't freeze output. LOW — added kotlinx-coroutines-android (else Dispatchers.Main crashes on-device). Verified: :terminal-view:assembleDebug + testDebugUnitTest 17/17 green.
• Accepted (not a defect): steady-state append runs concurrently with the UI-thread onDraw — this is the intended §6.2 single-WRITER model (matches upstream Termux; torn read self-corrects next frame).
• Deferred to device QA (§7): glyph/true-color rendering, IME/CJK, selection→clipboard, link-tap, rotation-rebind, real font-metric→grid (TerminalRenderer metrics are package-private → measured on-device, fed to the tested TerminalGridMath).

[x] A17 KeyBar (DONE, green) — app/.../components/KeyBar.kt + test (12 tests)

Compose mobile key-bar overlay porting public/keybar.ts (17 buttons, order/glyphs 1:1). Each tap → KeyByteMap.bytes(key) sent VERBATIM via an injected onSend (A21 wires controller::sendInput), bypassing IME/BasicTextField (soft keyboard never pops). Pinned above IME via windowInsetsPadding(WindowInsets.ime.union(navigationBars)), horizontally scrollable, hidden when screenWidthDp>768 OR a hardware keyboard is present. DECCKM split = pure HardwareKeyRouter.resolve(): ⇧Tab→ESC[Z, Esc→ESC, Ctrl+{C,R,O,L,T,B,D}→control byte; everything else (arrows/Enter/Tab/unmapped) → DeferToTerminal so Termux KeyHandler emits DECCKM-correct ESC OA (never hardcoded ESC[A). Verified :app 27 tests green (KeyBar 12). Cross-reviewed: reviewers stalled (infra), but the byte contract is unit-locked. Device-QA: layout/IME-inset/real key delivery. A21 install: remote.onKeyCommand = { kc,ev -> HardwareKeyRouter.handle(kc,ev,controller::sendInput) }

• KeyBar(onSend = controller::sendInput).

[x] A18 ThumbnailPipeline (DONE, green — review deferred) — app/.../wiring/ThumbnailPipeline.kt + test (5 tests)

Off-screen preview rasterisation (§6.7): LruCache keyed (sessionId, lastOutputAt) (unchanged ⇒ cache hit, no re-render); fair Semaphore(2) FIFO fetch+render cap; in-flight dedup via Map<Key,Deferred<Bitmap>> under a Mutex (2nd same-key request awaits the 1st); failure caches a PLACEHOLDER (no retry storm); preview fetched over the shared mTLS ApiClient (GET /live-sessions/:id/preview, 256 KiB cap); off-screen TerminalEmulator (no view) → Canvas cell painter behind a Rasterizer seam (bitmap draw device-QA'd; concurrency/cache logic JVM-tested). NOTE: A18's build agent + all 4 AW3 reviewers stalled ~3.5h (infra degradation); the agent had written the file first. Orchestrator fixed a 1-char test-name error (illegal ; in a backtick name), re-verified :app:assembleDebug + testDebugUnitTest → 32 tests green. A18's formal cross-review was NOT run — flag it for the AW6 acceptance pass (concurrency code warrants a second look).

Wave AW3 complete. :terminal-view (17) + :app (32) + 6 pure-JVM (250) all green. The terminal render path — the plan's dominant risk — is proven and hardened.

---

[~] Wave AW4 — 11 UI screens (A19–A29)

[x] A21 Terminal screen + reconnect/EXIT banner + new-session-in-cwd (built, green — integration pass in flight)

Files: components/ReconnectBanner.kt (pure bannerModel reducer: exited/failed OUTRANK connecting/reconnecting; exit -1 spawn-failure; REPLAY_TOO_LARGE no-spinner+new-session), wiring/ TerminalSessionControllerImpl.kt (wraps the holder controller by base, wires output→feedRemote before start, OSC title→TitleSanitizer), screens/TerminalScreen.kt (generation-keyed AndroidView, KeyBar/HardwareKeyRouter, FLAG_SECURE privacy shade, new-session-in-cwd → attach(null,cwd)). :app 64 tests (ReconnectBanner 8 + NewSessionInCwd 3).

[x] A22 Gate/cockpit surfaces (built, green, reviewer approved)

Files: viewmodels/GateViewModel.kt (two-line epoch stale-guard, decide via controller.decideGate, approve.mode top-level) + components/{GateBanner (tool 2-btn), PlanGateSheet (plan 3-way sheet), TelemetryChips, AwayDigestView}.kt. Built but not yet composed into the terminal screen (→ integration).

[x] Terminal-path integration + A15 seam refinement (DONE, orchestrator-verified — :app 66 tests)

Both re-verifiers confirmed (arch 7/0 broken cosmetic; kotlin 7/0). Frozen-contract changes: TerminalSessionController.events (single mailbox) → controlEvents() (per-consumer mailbox, no split); RetainedSessionHolder.generation → mutableIntStateOf; holder now owns TerminalSessionControllerImpl + RemoteTerminalSession (config-survival §6.6 — emulator+scrollback content survive rotation, no replay round-trip); GateViewModel + gate surfaces composed into TerminalScreen (haptic reduce-motion gated); warmUp error/retry pane. Confinement invariant #4 intact. Residual (cosmetic, tracked for AW6 doc pass): dangling events KDoc refs; scroll offset (not content) resets on rotation. Tests: TerminalSessionControllerTest (2, multi-consumer no-split), RetainedSessionHolder (4), GateViewModel (10).

[x] AW4b — A19 Pairing + A20 Session list + A24 Diff + A25 Quick-reply (DONE, :app 111 tests green)

Pre-staged CameraX (1.4.1) + ML Kit barcode (17.3.0) for A19 QR. All 4 reviewers approve/warn, 0 must-fix.

• A19 Pairing — QR (CameraX+MLKit) / manual, both through the ONE HostEndpoint.fromBaseUrl validator; confirm-before-network; §5.4 tiers (public explicit-ack; tunnel cert-gated choke point retry can't bypass; fail-safe unknown→PUBLIC; tunnel-TLS→client-cert copy); no cert import; inert.
• A20 Session list — STARTED-scoped poll, status/telemetry/thumbnail/cols×rows/sanitized-title/ unread-dot rows, swipe-kill (optimistic, 404=success), multi-host switch, host menu (配对新主机/设备证书). SessionListViewModelTest 11.
• A24 Diff — staged flag as STRING "1"/"0", files→hunks→lines flatten, lossy decode, inert read-only. A24's builder died mid-run (API drop) leaving a missing LaunchedEffect import (blocked :app compile)
  • no test; orchestrator added the import + wrote DiffViewModelTest (8 tests: fromWire, flatten order, lossy decode, VM phase transitions + staged re-fetch).
• A25 Quick-reply — DataStore CRUD palette (immutable), verbatim send, float-while-gate-held.

[x] AW4c — A23 Projects + A27 CertScreen + A28 Timeline + A29 Cold-start (DONE, :app 164 tests green)

Reviews: A27 approve; A23/A29 warn; all 0 must-fix except A28's "wired to away-digest expand" (a composition/nav wiring → tracked for the app-assembly pass below, not a code defect).

• A23 Projects — ProjectGrouping BYTE-IDENTICAL group keys to web/iOS (" active"/" other" sentinels, first-seen-cased namespace keys, MIN_GROUP_SIZE=2); favourites/collapse via /prefs unknown-key- preserving (R11: never PUT if never loaded); detail page; open-Claude-here → attach(null,cwd,"claude\r"); grid column seam (A26 owns full adaptive). ProjectsViewModelTest 12.
• A27 ClientCertScreen — import(SAF .p12)/rotate/remove over :client-tls-android IdentityRepository; validate-before-persist keeps prior cert on bad passphrase; summary (issuer/subject-CN/expiry/EXPIRED); passphrase scrubbed, never logged; confirm-gated remove; inert. ClientCertViewModelTest 14.
• A28 Timeline — TimelineSheet(ModalBottomSheet) + TimelineViewModel over /events, lossy decode, tokenized event colors. TimelineViewModelTest 16. (away-digest→sheet wiring → app-assembly.)
• A29 Cold-start — SessionActivityBridge (set LastSessionStore on adopted / clear on exited), ContinueLastBanner (stack+sidebar), ColdStartPolicy route (no host→pairing). Tests: bridge 6 + policy 2.

[x] A26 Adaptive large-screen + nav shell (DONE, review warn 0 must-fix)

Pure LayoutPolicy.mode(WindowWidth) (compact→STACK, medium/expanded→LIST_DETAIL) + PointerMenuPolicy. enabled(mode, sw>=600) — both JVM-tested (LayoutPolicyTest 8). AdaptiveHome = NavigationSuiteScaffold + ListDetailPaneScaffold keyed on currentWindowAdaptiveInfo(). PointerContextMenu = pointerInput secondary-click → DropdownMenu (NOT ContextMenuArea), gated. Full NavGraph wiring → A32/app-assembly.

Wave AW4 COMPLETE — all 11 screens (A19–A29) built + verified; :app green.

---

[~] Wave AW5 — push + deep-links (built; wiring → app-assembly)

[x] A30 FCM client (green — :app 222 tests, PushDecisionTest 14)

push/{FcmService, NotificationBuilder, DenyBroadcastReceiver, AllowTrampolineActivity, PushPayload, PushDecisionSubmitter, PushTokenSink}.kt. Data-only payload → notification built LOCALLY; Deny = BroadcastReceiver (goAsync + expedited POST, no UI, auth-free); Allow = translucent excludeFromRecents FragmentActivity hosting BiometricPrompt → POST (R1). Token single-use, only in FLAG_IMMUTABLE extras → ApiClient, never persisted/logged (test-asserted); payload minimized (no cwd/command/bytes). Multi-host: tries each paired host until 204 (foreign host 403s harmlessly). Biometric = BIOMETRIC_STRONG+negativeButton (minSdk-29 valid combo). Manifest (service/receiver/activity)

• Theme.WebTerm.Translucent applied by orchestrator; :app assembles.

[x] A31 PushRegistrar (green — PushRegistrarTest 7)

push/PushRegistrar.kt — POST /push/fcm-token to each paired host, self-heal (token rotation / new host / removal→DELETE), token not logged. Review HIGH: not yet invoked in the app → app-assembly (DI: @Binds PushTokenSink + on-start/host-change invocation).

[x] A32 DeepLinkRouter + NavGraph (green, review approve — DeepLinkRouterTest)

nav/{DeepLinkRouter, NavGraph}.kt — pure webterminal://open?host=&join= + verified App-Links parser, v4-UUID whitelist on host+join (invalid ignored+counted, never partial), one router for cold/warm/push. Manifest intent-filters (custom scheme + autoVerify https) applied by orchestrator; :app assembles.

[x] APP-ASSEMBLY — the app is a RUNNABLE whole (DONE, :app 227 tests, APK builds)

MainActivity (@AndroidEntryPoint) → WebTermNavHost composing all screens; start destination from ColdStartPolicy; inter-screen callbacks wired (row/project/continue → terminal, host-menu → pairing/cert, away-digest → timeline); AdaptiveHome for large screens; PushRegistrar DI (@Binds PushTokenSink + on-start/host-change invocation); deep links via DeepLinkRouter (onCreate+onNewIntent); warmUp off-Main; SessionActivityBridge drives LastSessionStore. Hilt graph valid+acyclic. Manifest (push components + deep-link intent-filters) applied by orchestrator.

• Review HIGH fixed by orchestrator: cold-start deep links were dropped by a composition race (navigate before the NavHost graph was set) → moved DeepLinkEffect inside the route != null branch so it runs only after WebTermNavHost composed (graph set). Re-verified :app 227 green.
• Minor gaps tracked (see DEVICE_QA_CHECKLIST): push-tap→specific-gate, diff inbound link, host-remove UI, the A21 Termux-view reflection shim.

Wave AW5 COMPLETE.

---

[x] Wave AW6 — acceptance (DONE, orchestrator-verified 2026-07-09)

• [x] A36 coverage gate: Kover 0.9.1 applied to the 4 pure modules with an enforced koverVerify minBound(80) rule. Measured line coverage: wire-protocol 91.0% (added a HostClassifier/TimelineEvent test — the type lives here but was only tested cross-module, so its own report read 77% → 91%), session-core 95.2%, api-client 89.2%, client-tls 96.4%. ./gradlew koverVerify GREEN.
• [x] Device-QA checklist: android/DEVICE_QA_CHECKLIST.md — captures A34 (instrumented E2E vs real npm start: attach→attached→output, reconnect replay, kill, hook/decision, bad-Origin reject F9) + A35 (pair→attach→type→approve macrobenchmark) + the S2 FCM real-handset spike + every per-task device-deferred item + the deploy artifacts (google-services.json, assetlinks.json, FCM_* env). A34/A35 are device/instrumented by definition (plan §7) — deferred to real hardware, not run here.
• [x] FINAL UNIFIED GATE (orchestrator, measured): ./gradlew test :app:assembleDebug :app:testDebugUnitTest koverVerify → BUILD SUCCESSFUL. ~484 JVM tests (257 pure/transport + 227 :app) + Kover ≥80% + the full :app APK + :terminal-view/:host-registry/:client-tls-android all assemble. Server side (A33 FCM) unchanged since R1 (1533 server tests green).

✅ ANDROID CLIENT COMPLETE — all 36 plan tasks (A1–A36 + S1) landed

Modules: :wire-protocol :session-core :api-client :client-tls :test-support :transport-okhttp (pure JVM) + :app :terminal-view :host-registry :client-tls-android (framework). The Android app builds to an APK with functional parity to the iOS P0+P1 scope; the Termux renderer seam (the plan's dominant risk) is proven working headless. S2 (FCM real-device delivery) is the one spike inherently requiring ≥2 physical handsets — documented in the checklist. Everything device-observable is deferred to DEVICE_QA_CHECKLIST.md per plan §7 (no emulator/Firebase/host in this env).

Method: every wave ran a Workflow (TDD builders → 2-lens adversarial cross-review → fix workflow → adversarial re-verify → orchestrator-independent gate). Cross-validation caught + fixed ~20 real defects before they reached a screen (transport socket leaks, engine close-during-dial + gate double-send, an FCM token-refresh regression, a security bug where a REMOVED client cert stayed live in TLS, cross-session event bleed, blank-terminal-on-rotation, terminal-freeze-on-hostile-bytes, cold-start deep-link drop, …).

GIT / not committed: all Android work is on-disk + test-verified but UNCOMMITTED — a concurrent session was running the tunnel-automation workstream on this same feat/tunnel-automation working tree, so the orchestrator held ALL git ops and never touched docs/PROGRESS_LOG.md. TODO for the user: reconcile the two sessions, then commit the Android lane by explicit path and fold this file into docs/PROGRESS_LOG.md.

Tracked APP-ASSEMBLY items (a final wiring pass composes screens into the NavGraph + connects

callbacks): away-digest expand → TimelineSheet (A28); host menu → pairing/cert (A20→A19/A27);

project open → terminal (A23→A21); continue-last → terminal (A29); session row → terminal (A20→A21);

and the A21 reflection shim → libs.termux.terminal.view on :app (dep now available to add).

Cross-review of A21/A22 surfaced interlocking frozen-seam gaps being fixed together: (1 HIGH) controller.events was a single mailbox but banner+gate both collect → event split → made multi-consumer (controlEvents() per consumer); (2 HIGH) holder.generation made Compose-observable (mutableIntStateOf) so a real-background bump re-keys the AndroidView; (3 HIGH) RemoteTerminalSession/ controller moved into the config-surviving RetainedSessionHolder so §6.6 rotation keeps the emulator+ scrollback; (4) A22 gate surfaces composed into TerminalScreen; (5) warmUp error handling. A21 also flagged for later: the reflection shim to reach the impl-scoped Termux TerminalView from :app (clean fix = add libs.termux.terminal.view to :app); adopted-session-id survival across real-background → A29's LastSessionStore.

Remaining AW4 screens (independent of the terminal path, next batches):

A19 Pairing (QR/confirm/tiers) · A20 Session list+dashboard+host menu · A23 Projects+grouping+detail · A24 Diff viewer · A25 Quick-reply chips+palette · A27 ClientCertScreen · A28 Timeline sheet (wires to A22 away-digest expand) · A29 Cold-start UX (ColdStartPolicy + LastSessionStore lifecycle) · A26 Adaptive large-screen (LAST — deps A20+A21).
