"Cherry-picked Phase 36 commits (d0d7a23a, b964c0e4, 11508547, fd372eaf, f8df2547) rather than re-implementing — all conflicts resolved manually"
"nexus-settings.ts service/route re-created from phase-36 content since files were not in HEAD before cherry-pick"
"assistantMemoryRoutes and assistantHandoffRoutes excluded from app.ts (route files absent on this branch)"

Phase 37 Plan 01: Server Prerequisites + VAD Browser Infrastructure Summary

One-liner: Cherry-picked Phase 36 voice pipeline (transcribe/synthesize/nexus-settings/voiceMode wiring), added COOP/COEP headers to Express and Vite, installed @ricky0123/vad-react, and served VAD ONNX model files from same-origin ui/public/.

Tasks Completed

Task	Name	Commits	Key Files
1	Cherry-pick Phase 36 server deliverables + COOP/COEP headers	`ee5538e5` (gsd/phase-37-web-chat-voice-ui)	server/src/app.ts (COOP/COEP headers)
2	Install VAD library, copy ONNX assets, configure Vite COOP/COEP	`fe74bcb0` (gsd/phase-37-web-chat-voice-ui)	ui/package.json, ui/vite.config.ts, ui/public/*.onnx, vad.worklet.bundle.min.js

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking Issue] pnpm-lock.yaml broken after cherry-pick conflict resolution

Found during: Task 2 (pnpm install step)
Issue: Cherry-pick conflict resolution produced malformed pnpm-lock.yaml with missing systeminformation@5.31.5 entry
Fix: Ran pnpm install --no-frozen-lockfile to regenerate the lockfile
Files modified: pnpm-lock.yaml
Commit: 0fb6b75d

2. [Rule 2 - Missing Critical Functionality] nexus-settings.ts service and route not present after cherry-picks

Found during: Task 1 (cherry-pick conflict resolution)
Issue: The HEAD branch did not have nexus-settings.ts (service or route) before cherry-picking; conflict resolution left them as untracked files
Fix: Created both files from Phase 36 branch content; staged and committed in e9eae5c4
Files modified: server/src/services/nexus-settings.ts, server/src/routes/nexus-settings.ts

3. [Deviation] assistantMemoryRoutes and assistantHandoffRoutes excluded

Found during: Task 1 (app.ts conflict resolution)
Issue: The cherry-pick added imports for assistant-memory.ts and assistant-handoff.ts route files which do not exist on this branch
Fix: Excluded those imports and route mounts from conflict resolution; included only chatFileRoutes, nexusSettingsRoutes, voiceRoutes
Impact: No functional loss — those routes are not needed for Phase 37

Known Stubs

None. All endpoints wire to real services (voicePipelineService, nexusSettingsService).
