# Next Steps — Resume Pointer

> **Last updated:** 2026-05-17.
> **Where we are:** Phase 2 mostly done. T-2.0..T-2.6, T-2.8, T-2.9, T-2.10, T-2.11 on main. App runs end-to-end on iPhone 12 mini + simulator. 130 unit tests (8 pre-existing failures), 12/12 UI tests green.
> **Where we go next:** T-2.7 PreConnectPool, T-2.12 TestFlight, T-2.13 MVP smoke. Plus: fix 8 pre-existing unit-test failures (4 Keychain entitlements + 4 Pairing http-scheme).

This document is the "where did I leave off" anchor. Read this first when
resuming work. The rest of `docs/` is reference.

## State at end of session

| Item | Status |
|---|---|
| Phase 0 — Stream Spike | ✅ done. Verdict GREEN with caveat (pipe-pane unreliable). Branch `feat/spike-stream` kept. |
| Phase 0.5 — Control-Mode Spike | ✅ done. Verdict: **Path B — tmux control mode**. |
| Phase 1 plan | ✅ updated to Path B. |
| Interface Contracts (IC-1..IC-4) | ✅ **frozen** 2026-05-15. |
| Phase 1 implementation | ✅ **done** 2026-05-15. All T-1.0..T-1.10 on main. Smoke 12/12. |
| Phase 1 — follow-up fixes | ✅ POST /pair smoke test, WS keys/key/paste handler, POST /sessions response shape. |
| Phase 2 iOS — T-2.0 scaffold | ✅ done. |
| Phase 2 iOS — T-2.1..T-2.5, T-2.9 core | ✅ done. WebSocket, Pairing, Terminal, ModifierBar, SessionConnection, APNs. |
| Phase 2 iOS — T-2.6 SessionSwitcher | ✅ **done** 2026-05-16. SessionRegistry + SessionSwitcher + SessionRow. |
| Phase 2 iOS — T-2.7 PreConnectPool | ⛔ not started. |
| Phase 2 iOS — T-2.8 StatusBar | ✅ **done** 2026-05-16. State indicator, action buttons. |
| Phase 2 iOS — T-2.10 Background lifecycle | ✅ **done** 2026-05-17. AppState.lifecycleTransitions publisher, SessionConnection suspend/resume w/ ResumeCursor, stale-frame freeze, post-Face-ID reconnect. 22 lifecycle tests + 6 follow-up. TDD pattern: tests → impl → review → fixup (B-1 + 3 nits + 4 coverage gaps). |
| Phase 2 iOS — T-2.11 Face-ID + Settings | ✅ **done** 2026-05-16. SettingsView, FaceIDGate, LockView. |
| Phase 2 iOS — T-2.12 TestFlight | ⛔ not started. Needs Apple credentials. |
| Phase 2 iOS — T-2.13 MVP smoke | ⛔ not started. |
| Phase 2 iOS — XCUITest infrastructure (bonus) | ✅ **done** 2026-05-16. piRemoteUITests target, 8/8 tests, `--uitest` mode, accessibility IDs, idb workflow documented in `docs/SIMULATOR-AUTOMATION.md` (iOS repo). |
| Bug Backlog | ⚠️ 8 pre-existing unit-test failures (4 Keychain `-34018` entitlements + 4 Pairing http-scheme tests). Not regressions, undocumented. |

Branches on remote `git.vpsj.de/jay/pi-remote-control`:
- `main` — all Phase 1 + follow-up fixes (latest: POST /sessions shape).
- `feat/spike-stream` — Phase 0 PoC, throwaway.
- `feat/spike-tmux-cc` — Phase 0.5 PoC, throwaway. Reference impl for T-1.1.

Branches on remote `git.vpsj.de/jay/pi-remote-ios`:
- `main` — T-2.0..T-2.6, T-2.8, T-2.9, T-2.11 + UI test target + idb docs.
- legacy `feat/p2-t2.*` branches kept for history; all already on main via merge commits.

## Open work (in priority order)

### Phase 2 remaining

- **T-2.7 PreConnectPool.** Hot WS per known session + cached last frame;
  switching shows the cached frame instantly with a "syncing…" pill.
  Touches: `Sources/Core/Sessions/PreConnectPool.swift` (new),
  `Sources/Core/Sessions/SessionConnection.swift`. Now safe to schedule
  after T-2.10's lifecycle hooks landed.
- **T-2.12 TestFlight pipeline.** Build / archive / upload scripts +
  internal testers list. Verify production APNs path. Needs Apple
  Developer credentials (paid program). Touches: `docs/DISTRIBUTION.md`,
  `scripts/` or Fastfile.
- **T-2.13 MVP smoke.** Manual on-device checklist: pair → render → input
  → backgrounded → push → reopen <1s → session-switch. Documents in
  `docs/PHASE-2-report.md` (iOS repo).

### Bug backlog (not regressions, pre-existing)

- **Keychain unit tests fail with `-34018` errSecMissingEntitlement** (4 cases).
  Likely needs Keychain-Access-Group in the test target's entitlements,
  or running under signed bundle. Investigate or skip with a documented reason.
- **Pairing unit tests `testParseQR_{http,https,wrongScheme}_throws` fail**
  (4 cases). Either the parser silently accepts http/https now (regression
  hidden by the `fp` optional change) or the tests need updating to match
  the new lenient behaviour.

### Phase 3 — not yet in scope

Slash palette, voice, themes, search, etc. See `docs/PHASE-3-ios-augmentation.md`.

## Reading order for resumption

1. `docs/NEXT-STEPS.md` (this file)
2. `docs/SYNC.md` — current claims, gate, contracts
3. `docs/PHASE-2-ios-mvp.md` — what's left to build for iOS
4. iOS repo: `docs/SIMULATOR-AUTOMATION.md` — how to drive the sim
5. iOS repo: `docs/BUILD.md` — build + install + launch commands
6. Spec only if you forget the why: `docs/reference/SPEC-ios-app.md`

## Conventions established

- **Async subagent dispatch.** All worker tasks via `subagent({ async: true, context: "fresh" })`. Worktree isolation for parallel-on-same-repo work; same-repo iOS+sidecar splits are inherently isolated.
- **Reviewer fan-in.** After parallel implementation, dispatch one reviewer agent with all branch summaries pre-loaded; reviewer writes `review.md` for the orchestrator to apply.
- **Sim test infra (`--uitest` mode).** Pre-fetch a fresh `/pair-qr` token per test, launch with `--reset-state --pair-with-url <url>`. `MainTerminalView` in `--uitest` mode skips the WS so XCUITest can reach app-idle within the 120 s window. Pasteboard prompt suppressed via `xcrun simctl privacy grant pasteboard de.vpsj.pi-remote`.
- **Sidecar manual restart pattern.** `tmux kill-session -t pi-sidecar; tmux new-session -d -s pi-sidecar -x 220 -y 50 "pi -nt -ne -ns -np -nc --no-session --offline -e extensions/remote-control --remote-control"`. Pre-fill 3 sessions (`main`, `work`, `logs`) for any manual E2E test.
- Don't expand scope. Stick to v3 spec; new ideas go into a v4 review
  round, not into open PRs.
