Estimated code review effort: 4 (Complex) | ~75 minutes Merge Risk: 🟡 Moderate · up to The PR moves transcription into environment APIs and adds browser voice controls. Loopback requests may expose credential-bearing traffic, and voice input can hide the stop-generation action; merge readiness is moderate until these issues are addressed. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Reviewed the new Effect service code (apps/desktop/src/speech/**, apps/desktop/src/ipc/methods/speech.ts, packages/contracts/src/speech.ts). Module layout, namespace imports, make/layer naming and dependency acquisition in DesktopSpeech.make follow the conventions. Three findings in DesktopSpeech.ts around runtime escapes and error modeling.

Reviewed the new web UI surfaces (composer mic button, Voice settings panel, desktop voice hook) against the shared component system and the shared voice-input contract. Four findings, all in apps/web/src.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a large cross-platform voice transcription capability with native model execution, audio transport, new settings, streaming, post-processing, and broad composer integrations. It also changes product defaults and adds static-analysis suppression directives, so the scope and policy-sensitive changes require human review. Not approved because:

In `@apps/server/src/speech/model.ts`:
- Around line 17-27: Update hasExpectedModel and the model lifecycle so
readiness checks avoid reading and hashing the full model: verify
SPEECH_MODEL.sha256 immediately after download and when the model is loaded,
while isSpeechModelReady uses the file-size check or a digest cache keyed by
size and mtime. Preserve failure handling for missing, unreadable, or invalid
model files.
In `@apps/server/src/speech/SpeechService.ts`:
- Around line 127-135: Update the finalizer around activeOperation so native
transcription shutdown has a bounded cancellation or termination path and scope
closure cannot wait indefinitely. Keep the model alive until the native
operation has completed or been safely terminated, then dispose it and clear
model and loading as currently done.
In `@apps/web/src/components/chat/ChatComposer.tsx`:
- Around line 5944-5950: Update the ChatComposer rendering around
resolveSpeechPresentation so ComposerFooterPrimaryActions remains mounted during
preparing, recording, and transcribing voice states. Remove the showsSend
conditional from the component mount decision, and instead pass the speech
presentation state or equivalent visibility control to hide only the send
actions while preserving ContextWindowMeter and its placeholder.
In `@docs/user/voice-input.md`:
- Around line 4-6: Update the voice-input workflow description to replace “stop
button” with “checkmark button” and “discard” with “X button,” preserving the
surrounding recording, transcription, and editing instructions.
In `@packages/client-runtime/src/voice-input/environment.ts`:
- Around line 50-51: Update the transcription request flow using
PreparedConnection.httpBaseUrl and client.voice.transcribe to reject
non-loopback http URLs before sending headers or PCM payloads; continue allowing
http only for loopback addresses needed by local environments, while preserving
HTTPS behavior.
In `@packages/contracts/src/environmentHttp.ts`:
- Line 572: Configure the `/api/voice/transcribe` route’s `MaxBodySize` or
`withMaxBodySize` using a limit no greater than
`SpeechService.MAX_SPEECH_BYTES`, so the request body is rejected before full
Uint8Array decoding; keep the existing payload schema and post-decode validation
unchanged.

Thanks for working on this. We merged the orchestrator V2 rewrite in #2829, and we are closing this PR as part of that transition. The patch conflicts with the rewrite in apps/server/src/environment/ServerEnvironment.ts, apps/server/src/httpCors.ts, apps/server/src/server.ts and 10 other files. Even where the conflict is small enough to rebase, we are asking for fresh PRs against the new base so we can review and verify the behavior in V2. Sorry for the extra work this creates. If the change is still needed on V2, please rebuild it on current main, verify it there, and open a new PR linking back here. We're closing the current implementation without assuming the underlying request is resolved. |
|
@juliusmarminge Thanks for the guidance. This work is continuing in #14882, which replaces this PR and links back here. The branch was backed up, rebased onto current main after the orchestrator V2 rewrite, and updated for the new integration points. The replacement has no merge conflicts. Focused validation passed 908 tests and typechecks for server, web, desktop, contracts, client-runtime, and shared. Please follow #14882 for further development and review of local voice transcription. |
