## Findings

No findings.

The iteration-08 callback race is closed. No simulator-testable or source-level correctness work remains in the reviewed scope.

## Acceptance Criteria

### Iteration 09 disposition

| Item | Result | Evidence / qualification |
|---|---|---|
| Gate old-room participant callbacks | Approved | `participantDidConnect` first requires current-room identity, then applies `shouldAcceptRoomCallback`, then mutates `agent` (`Sources/LiveKit/VoiceSession.swift:702-710`). The predicate accepts only `.connecting`, `.waitingAgent`, and `.ready` while `isTearingDown == false` (`:164-174`). |
| Gate connection-state mutations | Approved | The handler requires current-room identity, returns before all branches while `isTearingDown`, and restricts reconnecting/connected mutations to active lifecycle states (`VoiceSession.swift:748-769`). Terminal disconnect starts failure teardown only from `.ready`/`.waitingAgent`; inactive states cannot repopulate reconnect state (`:770-779`). |
| Final ephemeral reset | Approved | `teardownForFailure` publishes `.tearingDown` before any await, invalidates the generation, resets fields, awaits media/room teardown, resets again, and only then publishes `.failed` (`VoiceSession.swift:294-324`). Explicit disconnect uses the same before/after reset and publishes `.idle` only after teardown (`:528-553`). |
| Reset scope | Approved | `resetEphemeralFields` clears all nine per-room fields—agent, mute/user intent, mic error, models/selection, reconnect flags, and interruption ownership—without touching settings, transcript history/events, or task history (`VoiceSession.swift:142-162`). |
| Focused coverage | Approved with integration qualification | Six new predicate tests cover all active states, idle/failed/tearingDown, teardown overriding otherwise-active states, and the agent/reconnecting race scenarios (`Tests/ConversationStateTests.swift:175-246`). These are pure seam tests rather than injected LiveKit callbacks; exact production guard placement and final reset ordering were independently inspected. |
| Full verification | Approved | The complete simulator suite passed 65/65 in six suites, the separate simulator build succeeded, all six source files are in the generated test Sources phase, source counts equal the run total, and `git diff --check` is clean. |

### Previously approved finding regression check

- All previously accepted tests still pass: transcript symmetry/window/consume-on-suppress and canonical persistence; media desired-state/poll restart; server A→B→C replacement; resource-loader length/lifecycle; MediaAPI object responses; conversation-state and mic decision seams.
- Cumulative diff inspection found no regression in text-mode mic enforcement, explicit validated server Apply, failed-state replacement, failure/retry teardown truthfulness, media interruption suppression/sequence guard, stale-room media publishing, TLS host scoping, visible history/Clear, model-picker copy, or test discovery.
- Iteration 09 changes are localized to callback/reset logic in `VoiceSession.swift` and six additions in `ConversationStateTests.swift`; the reset preserves the durable stores explicitly required by the request.

## Verification Evidence

- Read `manifest.md`, `brief.md`, aggregate `review.md`, `iterations/08-review.md`, `iterations/09-request.md`, and `iterations/09-implementation.md`.
- Inspected the complete cumulative tracked worktree diff, exact `VoiceSession` callback/control paths, `ControlChannel`, the new callback tests, all test-source counts, and generated-project membership. Reviewer changed no product source, tests, configuration, generated code, or lockfiles.
- Loaded the repository XcodeBuildMCP skill. `session_show_defaults` confirmed project `/Users/shane/dev/voice-ios/Voice.xcodeproj`, scheme `Voice_iOS`, and iPhone 17 Pro simulator `AFDA137E-1657-428E-BF01-E5CD7989772C`.
- XcodeBuildMCP `test_sim` → **65 passed, 0 failed, 0 skipped** in 8.5 s; log line 309 confirms 65 tests in six suites and line 317 confirms success. Log: `~/Library/Developer/XcodeBuildMCP/workspaces/voice-ios-9eb036fdea81/logs/test_sim_2026-08-31T22-02-03-855Z_pid94423_2cf79d11.log`; result bundle: `~/Library/Developer/XcodeBuildMCP/workspaces/voice-ios-9eb036fdea81/result-bundles/test_sim_2026-08-31T22-02-03-855Z_pid94423_77ceed4b.xcresult`.
- XcodeBuildMCP `build_sim` → **Build succeeded** in 3.0 s. Log: `~/Library/Developer/XcodeBuildMCP/workspaces/voice-ios-9eb036fdea81/logs/build_sim_2026-08-31T22-02-14-911Z_pid94423_0052ca2d.log`. No Swift compiler warning was present; the only warning was expected AppIntents metadata extraction being skipped because the target has no AppIntents dependency.
- `rg -c '@Test\\(' Tests/*.swift` → ConversationState 16, MediaAPI 1, MediaReconcile 7, PinnedMediaResourceLoader 12, ServerReplacementCoordinator 5, TranscriptDedupe 24 = **65**.
- `Voice.xcodeproj/project.pbxproj:339-344` includes all six test files in the test Sources phase.
- `git diff --check` → clean after verification. `git status --short` remained the reported cumulative product/doc/config changes plus untracked `Tests/` and `.artifacts/`; tests/build introduced no product diff.

## Residual Risks

- **Real device:** microphone permission/capture, actual AVAudioSession mic and media interruption timing, remote TTS audibility, wake-lock behavior, mic-denied fallback, supported-format playback, and real LiveKit callback ordering remain unqualified by simulator seams.
- **Server format:** the current YouTube library remains webm and cannot qualify AVPlayer playback; device qualification needs a supported MP3/AAC/M4A endpoint. The resource loader still lacks a true server integration test.
- **Separate Hope UI implementation:** the LED-wall redesign, complete accessibility/Dynamic Type/reduced-motion pass, agent visualizer/barge-in refinement, and app icon remain intentionally separate and unimplemented.
- Plain LAN `ws://` signaling and self-signed certificate rotation remain documented deployment qualifications.

## Required Actions

No product-code action is required for this review. Build may close the correctness review while retaining the real-device, server-format, and separate Hope UI qualifications above.
