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.
