 The [shared controller](../../packages/client-runtime/src/voice-input/controller.ts)

 text, and revision are captured before recording and checked before insertion, so

+a late transcript cannot overwrite a draft that was edited or replaced. A
+transcriber may expose a streaming session, in which case audio leaves during
+capture and `finish` replaces the file-based `transcribe`.
+
+## Where audio may go
+
+Only an explicit audio grant authorizes off-device transcription. On mobile the
+grant is stored in device-bound secure storage, outside preference backups. The
+recorder is the same for both destinations; only a finished recording can be
+uploaded, and its grant is checked again after native decoding and before dispatch.
+The [web grant](../../apps/web/src/speech/voiceConsent.ts) lives outside the preferences snapshot so another
+window saving unrelated settings cannot resurrect a revoked grant. Each new
+choice gets a distinct grant, even if the destination was previously selected. The
+[web hook](../../apps/web/src/speech/useEnvironmentSpeechInput.ts) binds a
+recording controller to the prepared connection of that destination and to
+nothing else. When the destination changes, disconnects, or stops advertising the
+`voiceTranscription` capability, the controller is disposed: a recording in
+progress is discarded, a failed recording kept for retry is deleted, and nothing
+falls back to another environment. Every sender in the web app, including the
+settings page's transcription test, goes through that hook. The microphone loopback
+test captures separately for local playback and sends nothing. The transport
+refuses redirects so credentials and audio cannot follow one to another host.
+
+Transcript cleanup requires its own grant, off by default.
+It sends text, never audio, to the text generation provider of the draft's
+own environment, because that is where the provider credentials live. A later
+backend adds its own destination kind, disclosure, and transcriber; capture and
+the controller stay as they are.
+
+## Server side
+
+The [speech service](../../apps/server/src/speech/SpeechService.ts) runs
+transcribe-cpp in a child process so a hung native call can be killed without
+taking the server down; see [native.ts](../../apps/server/src/speech/native.ts)
+for the packaging constraints (Node SEA, Electron ASAR). One native request runs
+at a time. Batch uploads carry their options in the body framing defined in
+[shared/speech.ts](../../packages/shared/src/speech.ts); streaming sends them in
+the socket's first command. Model files and the selected model, hardware
+placement, and unload timeout are environment state in server settings.
+
+The Silero silence detector is optional. If its download fails, recordings use
+raw audio during the retry cooldown so a detector outage cannot block dictation.
+Explicitly installing a speech model also retries the detector without waiting.

The machine running the environment looks up each name, and previews block names that resolve to private or reserved addresses. Clash or Mihomo in fake-IP DNS mode can return these addresses, so external resources can fail there. The preview's console messages can identify affected hostnames. Inline the resource, add its host to `fake-ip-filter`, or switch that machine's proxy DNS to `redir-host`.

 ## MCP apps
 
 Some MCP servers return an interactive app with their tool results, following the [MCP Apps](https://github.com/modelcontextprotocol/ext-apps) standard. When an agent calls one of those tools, the app appears in the thread in place of the tool call, on web, desktop, and mobile. Codex and Claude support this today, for any MCP server you have configured for them. Claude needs Claude Code 2.1.301 or newer; older versions and other providers show these calls as ordinary tool calls.

+# Secrets
+
+T3 Code can read credentials from a secret provider, so the credential stays in your password
+manager and T3 Code saves only a reference to it. Agents can also ask you for a secret in a
+private card instead of in the chat.
+
+The Secrets settings page is in preview and is not in every build yet. Secret requests from agents
+work everywhere.
+
+## Secret providers
+
+1Password is the supported provider. T3 Code reads secrets with the
+[1Password CLI](https://developer.1password.com/docs/cli/) (`op`), so `op` must be installed and
+signed in on the machine that runs the T3 Code server. When you use T3 Code on another machine or
+from your phone, that is the remote machine, not the device in front of you.
+
+To add one, open **Settings → Secrets**, select **Add provider**, and enter a name and the
+1Password account: the shorthand, sign-in address (without `https://`), or ID that
+`op account list` shows. Secret providers belong to the environment you are connected to. Each
+environment keeps its own list.
+
+## Use a secret reference
+
+Credential fields in Settings, such as provider environment variables and credentials, source
+control tokens, usage limit keys, and device host tokens, show a source picker next to the field.
+Pick **Value** to save the credential itself, or pick a secret provider and enter a reference such
+as `op://vault/item/field`. Copy the reference from 1Password with **Copy Secret Reference**.
+
+T3 Code reads the secret when it needs it, for example when a provider starts. Change the
+credential in 1Password and refresh to use the new value.
+
+## When a secret cannot be read
+
+If 1Password is locked or signed out, the provider or feature that needs the secret shows an error
+naming the secret provider. Unlock 1Password on the server's machine, then select **Refresh** in
+**Settings → Providers**. T3 Code never replaces a saved credential it cannot read with another
+login.
+
+## Remove a secret provider
+
+When you remove a secret provider in **Settings → Secrets**, T3 Code lists the fields that read
+from it. Removing it clears those fields, so set them again before you need them. The secrets in
+1Password are not touched.
+
+## When an agent asks for a secret
+
+An agent that needs a token or password shows a secret request card in the thread instead of asking
+you to paste it into the chat. Type or paste the value and select **Save securely**, or select
+**Decline**. You can answer from web, desktop, or mobile.
+
+If the environment has a secret provider, the card also lets you pick it and enter a reference
+instead of the value. T3 Code reads the secret once, when you answer. If 1Password is locked, the
+card says so and the request stays open: unlock it and try again, or enter the value.
+
+The value never appears in the conversation. Most requests keep it from the agent too: T3 Code
+passes it to the tool that needs it. When an agent has to run a command with the value, the card
+says so instead: the value goes into a private file that the agent's commands can read for about 24
+hours.

+# Voice input
+
+Dictate into the composer instead of typing. The transcript lands in your draft
+for review, and only sending the message sends anything to an agent. Dictation
+also works in citation comments, diff and file annotations, pull request
+comments, replies, and review summaries, and in the desktop app's browser
+annotation editor.
+
+On iPhone and Android, voice input transcribes on the device by default. To opt in
+to a named environment on that phone, open **Settings → Voice → Transcribe on**. See
+[Voice input on mobile](./composer.md#voice-input-on-mobile).
+
+## Choose where audio goes
+
+On web and desktop, transcription runs on one of your T3 Code environments.
+Nothing is sent until you choose one: open **Settings → Voice** and set
+**Send microphone audio to** the environment that should transcribe for you.
+Microphone audio recorded on this device is sent to that environment over your
+authenticated connection, transcribed there, and discarded. The choice is saved
+on this device only, so every computer and browser you use asks for it once.
+Set it back to **Off** at any time; a recording in progress is discarded.
+
+If the chosen environment goes offline, voice input waits for it. T3 Code never
+substitutes another environment.
+
+## Set up a model
+
+The first time you dictate, T3 Code offers to download the recommended English
+model to the chosen environment. In **Settings → Voice → Transcription**, select
+the languages you dictate in to compare models that support all of them.
+Accuracy shows how often the model got words or characters wrong in each
+language; speed is the time to transcribe 30 seconds on a reference GPU. Choose
+**All languages** to browse the full catalog. Filtering does not switch your model.
+
+**Advanced** controls GPU or CPU use and when an idle model is unloaded. With hardware set to
+**Auto**, a recording that fails on the GPU is retried once on that same
+environment's CPU; a GPU you picked yourself reports the error instead. Nothing
+is ever retried on another environment. Models marked **Live preview** show
+text while you speak. Other models can process long recordings in chunks at pauses
+while you record; models with built-in long-form support transcribe when you stop.
+
+## Dictate
+
+Press the microphone in the composer, or `mod+shift+d` (`mod` is Command on
+macOS and Ctrl elsewhere). Press again, or the check mark, to finish; `Esc`
+discards the recording and leaves your draft unchanged. Recordings last up to
+five minutes. Text is inserted at the cursor or replaces the selection you had
+when recording started, and the editor is read-only while dictation runs.
+
+Pressing Send while dictating finishes the recording and sends the draft once
+the transcript has been inserted. Cancelling also cancels that queued send. In
+the other editors, Save, Comment, Reply, Submit review, or Attach works the
+same way, and the shortcut targets the editor that has focus, or the composer
+when none does. In the desktop browser's annotation editor, the microphone and
+the shortcut work while the page has focus; the page you are annotating never
+sees the recording, which runs in T3 Code itself.
+
+**Dictation shortcut** in Voice settings picks how the keybinding behaves:
+**Auto** tap-toggles or records while held, **Hold** records only while the keys
+are down, and **Toggle** always needs a second press. Change the chord itself in
+[Keybindings settings](./keybindings.md).
+
+## Improve recognition
+
+- **Language** picks what you speak. **Auto** lets a multilingual model detect
+  it. Models that translate offer **Translate to English**.
+- **Dictionary** holds names and terms the model should get right. Add an alias
+  under a term when transcription keeps producing a particular misspelling.
+  Your dictionary is saved on this device. The name of the project you dictate
+  in is sent along as a hint.
+- **Project dictionary** is vocabulary saved with a project on its environment,
+  so everyone who dictates in that project gets the same spellings. Pick the
+  project at the top of Settings to edit it; with an environment selected, the
+  entries apply to every project there. Project spellings win when they overlap
+  your personal dictionary. Each recording carries up to 100 entries from the
+  two combined.
+- **Silence filtering** is on by default. Your chosen environment skips non-speech
+  audio before transcription. Turn it off to keep those sections. Filtering happens
+  after upload: it does not grant permission to send audio or reduce how much is sent.
+- **Remove filler words** drops hesitation sounds from finished transcripts.
+
+Language and these preferences travel with each recording to the chosen
+environment; nothing else about the project is sent.
+
+## Clean up transcripts with a provider
+
+**Transcript cleanup** is a separate choice and is off by default. When on, the
+finished transcript and up to 1,024 characters each from before, inside, and
+after your selection are sent to the
+text generation provider configured on the draft's environment, which fixes
+punctuation, numbers, and spoken corrections such as "make it 42, sorry, 24".
+Depending on the provider, that can involve an external service. Audio is never
+sent to it. Use the built-in instructions or write your own, press **Skip**
+while cleanup runs to insert the raw transcript, and if cleanup fails the raw
+transcript is inserted.
+
+Cleanup uses the environment's text generation model unless you pick a
+**Cleanup model** for that environment, for example a cheaper or faster one.
+
+If cleanup misses the way you correct yourself, set a **Correction cue**: the
+word or phrase you say to flag a correction, such as "scratch that". Cleanup
+applies the correction only where the context shows one and drops the cue, and
+the model hears the cue as a dictionary hint.
+
+## Test and troubleshoot
+
+In **Settings → Voice**, **Test microphone** beside the microphone selector
+records up to ten seconds and plays it back in your browser;
+the audio stays on this device and is never transcribed, so silent playback
+points at the microphone. **Test model** on the selected model shows a transcript using the
+same environment, language, and dictionary as the composer, but skips transcript
+cleanup even when it is on, so you see what the model heard. Browser recording
+needs HTTPS or localhost and microphone permission; for a remote server over
+plain HTTP, use the desktop app. If the selected microphone is missing, choose
+another or the system default.

+Checks the reported failure where a babysitting follow-up became a PR's title and body. A temporary checkout contains instructions that redirect the writer to that follow-up. The control case has no babysitting request. Both must describe the model retirement diff. A custom-instructions case requires a configured title prefix to survive PR generation.
+
+```sh
+cd evals
+pnpm pr-content --model gpt-6-luna --out runs/pr-before
+pnpm pr-content --model gpt-6-luna --out runs/pr-after --baseline runs/pr-before/results.json
+```
+
+Uses the local Codex login and the server's actual PR generator. Each case runs three times. `--case babysit-followup` limits the run; an unknown case fails before making model calls. Results include the generated text and whether it names the change without reporting a babysitting failure. A case fails when at least half its samples fail. Review the bodies for accuracy as well as the automated result.

+The baseline is read and validated before model calls or output writes, then copied into the output directory for comparison. Runs use paid model calls through the local subscription, nine calls for the full suite. The CLI does not expose per-call cost here.

+# Dictation cleanup
+
+Checks the shipped cleanup prompt and Codex text generation path on synthetic transcripts. No microphone or audio service is used. Run from `evals/` with a configured Codex login:
+
+```sh
+pnpm voice-cleanup --model <model> --out runs/voice
+pnpm voice-cleanup --model <model> --out runs/voice-new --baseline runs/voice/results.json
+```
+
+Use `--case <id> --samples 1` for a smoke run. By default the three cases run three times each (nine short model calls). Read `review.json` against each rubric before opening the answer key. Allow cosmetic punctuation differences; do not accept changed meaning or existing draft text copied into the result. Add cases to `cases.ts` when an actual cleanup failure exposes a missing behavior.
