feat(server): transcribe audio on a chosen environment - #30625
This gives a T3 environment its own transcription engine. It does not turn on a microphone, choose a destination, or change mobile's on-device default.
Authenticated streaming and batch audio share a bounded, cancellable native worker. Only clients allowed to operate the environment can transcribe; changing models requires settings-write access. Models are pinned by digest.
Auto can recover once on the same machine’s CPU; it never redirects audio to another host. Transcript cleanup accepts text separately from audio.
Proof: synthetic speech was transcribed with an actual native Whisper model (batch) and Moonshine model (streaming) on Linux, through the authenticated app. Decoder, limits, stream lifecycle, permissions, interruption and same-host CPU recovery have focused coverage. The replacement downloader also installed a fresh 34 MB Moonshine Tiny through the app, matched its pinned SHA-256, and transcribed the sample as “Add a test for the microphone.” Three transcript-cleanup examples were each run three times with a live model (9/9).
A model-management download occupies the environment's single speech operation slot; another recording can report busy until it finishes.
Follow-ups from @UtkarshUsername: #30758 sends generic vocabulary hints only to models that support them, #30821 generates the pinned catalog, and #30855 preserves the recording if an auto-selected GPU fails during finalization and retries once on the same host’s CPU.
Based on #14882 by @UtkarshUsername. Thank you for the native inference, model discovery, and dictation workflow.
Macroscope's review found this PR requires human approval — Adds environment-hosted transcription with verified model downloads and optional transcript cleanup. New diagnostic suppressions and speech defaults require human review; unresolved findings also report ignored streaming translation and disconnects that can temporarily block speech operations.
Needs human approval because:

This PR adds local speech transcription, model management, authenticated speech endpoints, and optional transcript post-processing. It adds shared speech contracts and settings, provider support, and client voice-input handling.
Changes: Local speech transcription and voice input
Adds speech schemas, settings, PCM request framing, vocabulary and language utilities, post-processing model selection, and the voiceTranscription environment capability. Linux libc detection is shared with resource-monitor target selection.
Model catalog and native worker apps/server/src/speech/model.ts, apps/server/src/speech/catalog.json, apps/server/scripts/speech-catalog.ts, apps/server/scripts/sync-speech-catalog.ts, apps/server/src/speech/native.ts, apps/server/src/cli/speechWorker.ts, apps/server/src/bin*.ts, scripts/build-desktop-artifact.ts, scripts/lib/cli-external-packages.ts, pnpm-workspace.yaml
Adds a speech model catalog and an isolated native worker for model loading, GPU discovery, transcription, and streaming. Adds worker command dispatch and native dependency packaging configuration.
Verified model storage apps/server/src/speech/SpeechModelStore.ts, apps/server/src/speech/SpeechModelStore.test.ts
Adds model readiness and integrity checks, resumable downloads, size and hash verification, cancellation handling, and removal of model files and verification markers.
Transcription service and text correction apps/server/src/speech/SpeechService.ts, apps/server/src/speech/customWords.ts, apps/server/src/speech/fillerWords.ts, apps/server/src/speech/SpeechService.test.ts
Adds PCM validation, model lifecycle and operation management, batch and streaming transcription, automatic CPU recovery, custom-word correction, and filler-word removal.
Transcript post-processing and provider support apps/server/src/speech/postProcessing.ts, apps/server/src/textGeneration/*, packages/provider-core/src/server/*, packages/provider-*/src/server/*, packages/shared/src/serverSettings.ts, evals/voice-cleanup/*
Adds a text-generation operation and prompt builder for transcript cleanup. Provider implementations and unsupported-operation handlers expose the operation. Adds evaluation fixtures, a runner, and usage documentation.
Adds authenticated HTTP speech and model-management handlers, request-size enforcement, and a WebSocket stream route. Server composition provides the speech services and routes.
Adds streaming completion, retained-recording retries, post-processing and skip behavior, cancellation handling, and optional fetch request settings. The mobile presentation treats post-processing like transcription.

Merge Risk: Moderate · previous review 32888
Speech model management can get stuck busy after a download of an already-installed model. A failed stream start can block other speech operations until the socket closes. Cleanup with an unusable configured model fails instead of falling back. Fix the busy-state and slot-release issues before merging.

Explanation
The title "feat(server): transcribe audio on a chosen environment" matches the main change. The changeset adds server-side speech transcription (batch and streaming) through an environment HTTP API, native speech worker, model store, and voice capability reporting. The title is short, follows conventional-commit form, and names the primary capability. It does not mention the streaming or model-management details, which is acceptable.
Full details: Description check
Explanation
The description covers the required sections of the template in substance. The Problem section is missing its own heading, so the problem statement is not explicit. The description states what the change does, what it does not do, and how it was verified (Linux tests with native Whisper and Moonshine models, a SHA-256-matched download, and cleanup evals). It also references a follow-up list and a base PR. The Scope and approval section is not clearly filled: it links neither a triaged issue nor a maintainer approval comment, and the base PR #14882 is cited without an explicit approval statement. The template requires a link to the triaged issue or approval comment, or an explanation of why the change qualifies without one. The verification section is detailed, though it includes no before/after screenshots, which is not required for this server-side change. The agent attribution line is present.
Resolution
Add a clear Problem section with the problem statement, expected behavior, and reproduction context. Add the Scope and approval section content: link the triaged issue or the maintainer-approved discussion, including the approval comment, or explain why the change qualifies without prior approval. Keep the existing Verification details, and ensure the Change section explains how the implementation addresses the problem.

Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Exclude the restricted Moonshine models.
The catalog labels moonshine-tiny-ja and other legacy non-English Moonshine models as mit, so this filter retains them. Their actual license restricts commercial use. The runtime offers them without those restrictions. (raw.githubusercontent.com)
Exclude the affected model IDs despite the upstream metadata, then regenerate the catalog and test the exclusions.

Confirmed the Moonshine catalog finding against the publisher’s list of covered weights. 62ebd0d removes the 12 affected legacy Base/Tiny model entries from our pinned catalog and excludes Spanish Base on future syncs. English and streaming models remain available. The regression test failed on Japanese Tiny before the fix; all catalog tests and the changed-file checks now pass.

Clear the settled fiber after awaiting it.
Effect.forkIn(scope) can run the queued child before the assignment to downloading when the parent reaches its operation-budget yield. For an already verified model, the child can complete immediately, so its ensuring callback sees no state to clear. Line 314 then stores the settled fiber, and later model-management operations remain stuck behind SpeechBusyError.
Keep the local fiber handle and clear a matching record after Fiber.await returns. This handles both success and failure without changing the normal cleanup path.

In the model-download flow, a child fiber can finish before `downloading` is
assigned, leaving a settled fiber recorded and causing later operations to
remain busy. Keep a local fiber handle through `store.download` and
`Fiber.await`, then clear `downloading` and call `scheduleUnload()` after the
await only if the record still references that fiber; preserve the existing
cleanup path for normal completion.

apps/server/src/speech/SpeechService.ts:636-675 Minor · Stability & Availability · Quick win
Release the speech slot when startStream fails.
startStream reserves activeOperation and increments activeTranscriptions before readSettings, model selection, and loadModel run. The release runs only in the finalizer attached to the socket scope. If one of those steps fails, the finalizer does not run until that scope closes. fail in stream.ts writes the 1008 close event but does not end the read loop, so the scope can stay open until the client closes the socket or the 10-minute read-loop timeout fires. Until then, operationBusy() rejects other speech operations with SpeechBusyError, and the cached model stays loaded.
Run the same release effect when the remainder of startStream fails. Guard it so the scope finalizer does not release twice.
Wrap the statements from const settings = yield* readSettings(operation); through the returned stream in Effect.onError(() => releaseSlot). Keep the body of releaseSlot unchanged.

Update startStream so failures after reserving activeOperation and incrementing
activeTranscriptions release the speech slot immediately, rather than waiting
for the socket scope to close. Reuse the existing finalizer cleanup through a
shared, idempotent release operation, and invoke it on errors from the remaining
startStream work; ensure the scope finalizer cannot release twice.

Both outside-diff findings reproduced on 3288856. Fixed in 79bfb23 and carried through the stack.
Cached download: the regression used to see downloading after the transfer had finished. It now sees installed and can select a different model immediately. Disconnecting the request still leaves a real transfer running and joinable.
Failed stream start: when native begin rejects, the service now reports ready before the socket closes. A second stream starts, the old socket closes, and the second stream still finishes normally.
Both regression tests failed before the fix. The service, socket, and HTTP suites pass on the engine (36 tests) and with the optional silence detector integrated (44 tests). Both changed-file checks passed.

A normal WebSocket disconnect can leave SpeechService.openStream and its activeOperation running until the 10-minute timeout, blocking other recordings and model operations. When pending is full, Queue.offer suspends this loop before it can call reader.pull and observe the close; observe disconnects independently of the queue and interrupt the stream scope.

22 upstream commits, mostly environment dictation (pingdotgg#30623, pingdotgg#30624, pingdotgg#30625,
pingdotgg#31059) and secret providers.
Conflicts:
- server.ts: pingdotgg#30625's speech stream route beside the Tailscale pairing
renewal (section 6).
- environmentHttpTest.ts: pingdotgg#30625's voice body limit beside the forbidden
operation error.
- SettingsRouteScreen.tsx (mobile): the pane-role refactor drops the
workspace context import; settingsPageLabel stays (section 2).
The voice controller is a display file, so 13 of its errors reached the new
composer error pill in Chinese and missed the pill's English-keyed labels:
every error read "Voice input failed" and Retry transcription never showed.
The pill now reads them through englishVoiceError, with a fork test.

Superseded: side chats keeping the main thread's permission mode now come from upstream pingdotgg#31114; Cody's ThreadForkService, ProviderTurnStartService and useSideChat overrides are gone and the docs line about it is removed.
Superseded: the web scheduled task row's "Posts to" label gives way to upstream's link to the thread (pingdotgg#31764); mobile keeps the label beside upstream's Open thread action.
Adapted: the "Post runs to" picker sits beside upstream's thread mode Destination (pingdotgg#30326). Picking a thread sets a one-thread mode, "no thread" is offered only where a save can unbind, and saves send threadMode, since the server now keeps a stored thread unless the mode is new_thread. Shared rules live in scheduledTaskThreads.ts; upstreamWiring.test.ts pins the web and mobile calls.
Adapted: upstream's Labs zen view (pingdotgg#30000) also keeps the answer before a short wrap-up, on web and mobile, with zen cases in both wrap-up tests.
ChatView.logic: Cody's worktree base ref plus upstream's fresh-context dispatch mode (pingdotgg#30325).
agentContextBudget.json: upstream's new sizes plus Cody's 371-byte final answer block.
build-desktop-artifact.test: mac and Linux now unpack @transcribe-cpp libraries (pingdotgg#30625).
Skill sync notes updated for thread modes, side chat permissions and the zen view.
Claude Opus 5.5 via OpenCode in T3 Code.
Upstream's transcription (pingdotgg#30625) unpacks 13 DLLs on Windows x64. Cody builds Windows on Windows hosts, whose payload already carries about 16 files upstream's Linux cross-build leaves out, so the x64 build hit the 80-file limit at 83. Cody's limit is now 96.
Claude Opus 5.5 via OpenCode in T3 Code.
Adopt upstream's environment speech service (pingdotgg#30625) for dictation and drop the
fork's Parakeet transcription: its voice RPCs, server layer, web composer button,
composer.toggleDictation shortcut, sherpa-onnx-node dependency and build staging.
Both declared the same voiceTranscription capability.
