Problem

Mobile voice input currently requires Apple's on-device transcription, so it only exists on iOS 26+ iPhones — Android and older iOS have no mic button at all (#8718). docs/internals/voice-input.md (added in #8614) already specifies how environment-provided transcription should work, but it was unimplemented.

Change

Implements that spec as written:

  • Environment owns the credential. An OpenAI transcription API key is entered in web Settings → Voice input, persisted in the server's ServerSecretStore with its own explicit redaction — clients only ever see valueRedacted: true. Model defaults to gpt-transcribe, overridable in settings.
  • Capability-gated catalog. A transcription capability on ExecutionEnvironmentCapabilities, plus a derived transcriptionServices list (ids and labels only) on ServerConfig and the settingsUpdated payload. Older servers expose no remote choices; adding/removing the key updates availability live.
  • One-shot signed upload, nothing persisted. The client mints a short-lived signed URL over an authenticated RPC (mirroring the attachment-upload token pattern), POSTs the recording, and gets the transcript back in the same HTTP response. The server buffers in memory (25 MB cap, exact Content-Length enforcement) and forwards to OpenAI; audio is never written to disk, and aborts propagate to the upstream request.
  • Shared environment transcriber in packages/client-runtime implementing the existing VoiceTranscriber contract, with an injected platform transport (expo-file-system upload on mobile, matching the attachment transport split). Environment, service, and locale are captured when a recording starts; a disconnected environment reports unavailable rather than silently falling back.
  • Per-environment source picker on mobile (Settings → Environments): "On this device" vs the environment's service, stored per stable environmentId. Defaults to local when available, otherwise the environment service.
  • Android and iOS < 26 gain voice input automatically wherever an environment advertises transcription — the existing composer mic UI just becomes available.

Web/desktop voice capture remains out of scope, per the spec's boundaries; web only gains the settings section.

Relationship to #5213: that branch covers web/desktop BYOK dictation and has no apps/mobile code; this PR covers the mobile surface against the newer internals spec. Fixes #8718.

Verification

  • End-to-end on an iOS 26.5 simulator: spoken audio → recording → signed upload to the environment → OpenAI → transcript inserted in the composer ("T3 code voice transcription simulator verification."). Silence correctly surfaces the existing "No speech was detected." retry state.
  • Focused tests: server settings round-trip/redaction and transcription route (48), client-runtime environment transcriber and controller (68); targeted typecheck and lint on the five touched packages.

Note

Medium Risk
Touches authenticated upload/transcription HTTP, secret persistence, and OpenAI forwarding with in-memory audio handling; mobile behavior changes when environments advertise transcription.

Overview
Adds environment-backed voice transcription so mobile can transcribe recordings via the connected server (OpenAI) when on-device speech is unavailable, not only on iOS 26+.

Server & contracts: New transcription capability, transcription.createUrl RPC, and a signed one-shot POST route that validates token/size, buffers audio in memory (no disk), and returns { text } from OpenAI. OpenAI API key and model live in server settings, stored in the secret store and redacted to clients; transcriptionServices is advertised on config and settingsUpdated events.

Shared client: createEnvironmentVoiceTranscriber mints URLs, uploads via injectable transport, and honors AbortSignal through atom commands. Server state exposes per-environment transcription service lists gated by capability.

Mobile: Composers pass environmentId into useVoiceInputController, which resolves local vs remote from persisted voiceTranscriptionSources. Settings → Environments adds a per-environment Voice transcription picker ("On this device" vs OpenAI). Mic availability becomes local or any advertised environment service.

Web: General settings gains Voice input (API key + model). Docs updated for mobile/environment flow.

Note

Add environment-backed voice transcription for mobile

  • Adds transcriptionCreateUrl WebSocket RPC and transcriptionRouteLayer HTTP route to issue signed URLs and forward audio to OpenAI.
  • Adds TranscriptionSettings to ServerSettings, storing the OpenAI API key in a secret store and redacting it for clients.
  • Implements environmentVoiceTransport on mobile to upload recordings and updates useVoiceInputController to select local or environment transcribers.
  • Makes iOS Apple team ID and associated domains conditional for Personal Team builds in app.config.ts.
  • Risk: transcriptionCreateUrl RPC requires AuthOrchestrationOperateScope; useVoiceInputController now requires an environmentId input.

Macroscope summarized ebc8e4a.

Effect.exit swallows the request failure and the cause is never preserved or logged, so the returned 502 carries no diagnostic trail (and an interruption is reported as a request failure too). storeAttachmentUpload keeps the cause via Effect.logError(..., { cause }); consider doing the same here, and for the schemaBodyJson exit below (line 167) whose decode error is also discarded.

The signing-key failure is dropped entirely here, so a broken secret store surfaces only as an opaque 404 with no cause anywhere in the logs. The sibling token validators (validateAttachmentUploadToken, AssetAccess) log the cause before falling back — consider matching them so the underlying failure is preserved.

This manufactures a bare Error purely so the catch below can wrap it as cause, and it puts the raw upstream response body into the error message. Throwing the domain error directly at the failure boundary keeps the structural code plus the safe HTTP status and drops the unbounded body text.

throw new Error(response.bodyText || `Transcription failed (${response.status}).`);
throw new VoiceTranscriptionError(
"transcription-failed",
`The environment could not transcribe the recording (${response.status}).`,

Stale source blocks local transcription

Medium Severity

A persisted environment source is used even when that service is no longer advertised. isAvailable stays true whenever on-device transcription exists, so the mic remains shown, but getTranscriber still builds the environment transcriber and preparation fails. The settings row also disappears once services is empty, so there is no way to switch back to On this device.

This row rebuilds the shared commit-on-blur field (DraftInput / useCommitOnBlur, already imported in this file) with a local draft plus a useEffect resync. The reconstruction drops Enter-to-commit, which every other server-backed settings text field supports, and the effect-based resync can overwrite an in-progress edit when the optimistic settings push lands, whereas useCommitOnBlur only resyncs while unfocused.

Suggested fix — use the primitive and delete transcriptionModelDraft's useState/useEffect at the top of GeneralSettingsPanel:

<DraftInput

  value={settings.transcription.model}

The trailing action is sized off the shared control scale used elsewhere: Input (default) is h-8.5 sm:h-7.5, while Button size="xs" is h-7 sm:h-6. Because the wrapper is flex without items-center, the shorter button stretches to flex-start and renders top-aligned and visibly smaller than the field. Every other input+action pair in settings matches sizes (default Input → default Button, compact → compact) and marks the action shrink-0 so the field absorbs the width.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a substantial mobile-to-environment-to-OpenAI transcription workflow, including authenticated upload routes, secret-backed API-key settings, shared runtime changes, and a new default model. The signed upload URL can currently be reused to trigger repeated OpenAI requests, and stale mobile selections can make transcription unavailable, so the production and security implications require human review.

Validate the persisted source before selecting a transcriber.

When selection.selectedSource contains a removed service ID, the nullish fallback does not run. The controller passes that ID to createEnvironmentVoiceTranscriber, whose prepare() throws VoiceTranscriptionError when the current service list does not contain it. Treat the saved ID as unset unless selection.services contains it, then select the local transcriber or first available service.

Prevent repeated use of transcription upload URLs.

POST /api/transcription/* accepts the same unexpired signed URL more than once. Each upload reaches transcribeWithOpenAi and can incur additional OpenAI usage charges. Add an atomic single-use reservation for each URL. Define whether failed uploads consume the reservation. This limits replay of an exposed URL, but does not limit an authenticated caller with AuthOrchestrationOperateScope who can mint additional URLs.

Reset voice-input drafts when the primary environment changes.

GeneralSettingsPanel remains mounted while usePrimaryEnvironmentId() and useUpdatePrimarySettings() switch targets. An unsaved transcription key or model can therefore be saved to the newly selected environment. Reset both drafts when environmentId changes.

Proposed fix
   const [transcriptionKeyDraft, setTranscriptionKeyDraft] = useState("");
   const [transcriptionModelDraft, setTranscriptionModelDraft] = useState(
     settings.transcription.model,
   );
+  useEffect(() => {
+    setTranscriptionKeyDraft("");
+  }, [environmentId]);
   useEffect(() => {
     setTranscriptionModelDraft(settings.transcription.model);
-  }, [settings.transcription.model]);
+  }, [environmentId, settings.transcription.model]);

Mark both transcription rows as serverScoped.

When the hosted app has no primary environment, SettingsRow leaves these controls interactive by default. Their useUpdatePrimarySettings() calls then cannot persist the server patch and report that the setting was not saved. Match the analogous primary-server controls:

Proposed fix
         <SettingsRow
+          serverScoped
           {...searchableSetting("openai-transcription-key")}
           ...

         <SettingsRow
+          serverScoped
           {...searchableSetting("openai-transcription-model")}
           ...

Bugbot is paused — on-demand spend limit reached

Bugbot uses usage-based billing for this team and has hit its on-demand spend limit.

A team admin can raise the spend limit in the Cursor dashboard, or wait for the next billing cycle to continue.

Fold the fork's server-side transcription into upstream's v0.0.39 refactors:
the extracted static request handler in http.ts, usage-limit secret handling in
serverSettings.ts, the usage-limits-aware loadServerConfig in ws.ts, and the
renamed thread-list shelf preference keys on mobile.

Give the Voice input settings section an id and a sidebar nav entry to match the
new scroll-spy convention, and rewrite both voice docs in upstream's current,
shorter voice.
