feat(capture): dictation, personalities, 0.5.0

Ships the Capture release end to end. Global-hotkey dictation with
synthetic paste into the focused app on macOS and Windows, an on-screen
pill across recording / transcribing / refining, customizable push-to-
talk and toggle chords, and an accessibility-permission prompt scoped to
Settings → Captures with inline re-check feedback.

Voice profiles gain optional personalities that power compose / rewrite /
respond actions via a local Qwen3 LLM — shared with refinement, so there
is one local LLM in the app, not two.

Refinement hardened with deterministic Whisper-loop collapse before the
LLM sees the transcript, per-capture flag snapshots for re-runs, and a
ten-transcript evaluation harness across every bundled refinement size.

Version bump 0.4.5 → 0.5.0.

 ## [Unreleased]
 
+## [0.5.0] - 2026-04-22
+
+**The Capture release.** Voicebox stops being a voice-cloning studio and becomes an AI voice studio. The loop closes in both directions: your voice goes into your computer through a global hotkey, and any agent's voice comes out of your computer through a voice you own.
+
+Hold a key anywhere on your machine, speak, release — the transcript lands in the focused text field in whatever app you were using. Flip the primitive around and any MCP-aware agent — Claude Code, Cursor, Cline, Spacebot — speaks back through the same on-screen pill in one of your cloned voices. A local LLM sits between the two, so transcripts come out clean and voice profiles can carry a personality that reshapes what the agent actually says before it gets spoken.
+
+Everything still runs on your hardware. No cloud, no accounts, no audio leaving the machine.
+
+### Dictation — speak anywhere, paste anywhere
+
+- **Global hotkey capture.** Hold a customizable chord anywhere on your machine (defaults: right-Cmd + right-Option on macOS, right-Ctrl + right-Shift on Windows), speak, release. A floating on-screen pill surfaces over your current app and walks through recording → transcribing → refining → done with a live elapsed timer during the clip. Your dictation lands as a clean transcript.
+- **Push-to-talk and toggle modes, each with its own chord.** The default toggle chord adds Space to the push-to-talk chord. Holding PTT and tapping Space mid-hold upgrades a hold into a hands-free session without a gap in the recording — the session rolls forward, you stop when you want.
+- **Auto-paste into the focused app.** Once transcription finishes, Voicebox synthesizes a platform-native paste into whatever text field had focus when you started the chord — not wherever focus drifted while you were talking. Your clipboard is saved before and restored after, so nothing you had copied goes missing.
+- **Chord picker UI.** Customize either chord from Settings → Captures by holding the keys you want. Left/right modifier badges show whether a key is the left or right variant, so you can pick the exact hardware signature you want to capture.
+- **Defaults picked to stay out of your way.** macOS defaults deliberately avoid left-hand Cmd+Option chords so Cmd+Option+I (devtools), Cmd+Option+Esc (force quit), and Cmd+Option+Space (Spotlight) all remain yours. Windows defaults route around AltGr collisions on German/French/Spanish layouts where Ctrl+Alt synthesizes AltGr.
+- **Accessibility permission is scoped.** The macOS permission prompt lives inline next to the auto-paste toggle in Settings → Captures, not as a global banner on every page. If permission isn't granted, dictation still runs and transcripts still land in the Captures tab — only synthetic paste is disabled.
+
+### Personality — voice profiles that speak for themselves
+
+Voice profiles now carry an optional **personality** — a free-form description of who this voice is, up to 2000 characters. When set, three new actions appear on the profile, each powered by a bundled Qwen3 LLM running entirely locally:
+
+- **Compose** — generate fresh utterances in the character's voice. Click again for variety.
+- **Rewrite** — restate your text in the character's voice while preserving every idea. High-fidelity mode for turning dictation into in-character speech.
+- **Respond** — treat your text as a prompt and produce the character's reply.
+
+Temperatures are tuned per mode (compose hot for variety, rewrite cold for fidelity, respond balanced) and the character framing enforces "speech only" output — no narration, no action tags, no meta-commentary. The same LLM doubles as the refinement model, so there's one local LLM in the app, not two.
+
+### Agents — any MCP-aware agent gets a voice
+
+> **Note:** the MCP server implementation is not yet in this tag. The pieces it depends on — the personality/compose/rewrite/respond runtime, voice-binding-per-profile, and the on-screen pill as a generic surface — are all in place. The MCP route lands in a follow-up commit before the final 0.5.0 tag.
+
+Once the MCP server ships, any MCP-aware agent — Claude Code, Cursor, Cline, Spacebot — can call `voicebox.speak({ profile, text, intent })` and Voicebox will produce in-character speech in the bound voice. The on-screen pill surfaces whenever an agent is talking so you always see what's coming out of your machine. Pin Claude Code to Morgan, Cursor to Scarlett, Spacebot to its own voice — you can tell which agent is speaking without looking.
+
+### Refinement hardening
+
+Refinement shipped earlier; 0.5.0 closes the stubborn edge cases:
+
+- **Deterministic loop-stripping before the LLM sees the transcript.** Whisper's "thanks for watching thanks for watching thanks for watching…" hallucination loops are collapsed at a six-identical-tokens threshold (case-insensitive) so a small refinement model can't echo them back. Legitimate repetition ("no, no, no, no, no") doesn't cross the threshold.
+- **Refinement flags snapshot per capture.** `smart_cleanup`, `self_correction`, and `preserve_technical` are stored on each capture, so refinement can be re-run later with different flags without losing the raw transcript.
+- **Ten-transcript evaluation harness** (`backend/tests/test_refinement_samples.py`) scoring prompt leaks, answer leaks, loop echoes, filler removal, length-ratio outliers, substring preservation ("npm install", "handleSubmit"), and question-mark survival against every bundled refinement model size.
+- **Refinement model picker** — Qwen3 0.6B (400 MB, very fast), 1.7B (1.1 GB, fast), 4B (2.5 GB, full quality). 0.6B is the default; 1.7B is the sweet spot for transcripts with code identifiers.
+
+### Captures tab + settings
+
+Settings → Captures is now the home for the whole dictation flow:
+
+- **Dictation**: global shortcut toggle, push-to-talk chord picker, toggle chord picker, live pill preview, copy-transcript-to-clipboard, auto-paste into focused field (with inline accessibility prompt).
+- **Transcription**: model picker (Whisper Base / Small / Medium / Large / Turbo), language lock, archive-audio toggle.
+- **Refinement**: auto-refine toggle, model picker, smart cleanup, remove self-corrections, preserve technical terms.
+- **Playback**: default voice for the Captures tab's "Play as" action.
+- **Storage**: retention (forever / 90d / 30d / 7d), clear-all-captures.
+
+### Windows parity
+
+- **Synthetic paste** via `SendInput` with correct scan codes, plus a `SetForegroundWindow` + `AttachThreadInput` handshake to defeat foreground-lock when pasting into a window that wasn't frontmost at chord-start.
+- **Right-hand default chord** (Ctrl+Shift) to avoid AltGr collisions on layouts where Ctrl+Alt is the compose key.
+- **Focus capture via UIAutomation** for control-class identity and `GetForegroundWindow` for window identity, snapshotted at chord-start so paste lands in the original field even if focus drifts during transcribe/refine.
+- **UAC/UIPI caveat**: synthetic paste into an elevated window from a non-elevated Voicebox is blocked by Windows itself. Run Voicebox elevated if you regularly dictate into elevated apps.
+
+### Landing page — /capture
+
+New `/capture` route tells the Capture story end-to-end. Hero line: *"Just talk to your computer."* Three pillars — multi-engine STT (Whisper, Whisper Turbo, Parakeet v3, Qwen3-ASR), refined transcripts, agents speaking in voices you own. Drop-in MCP config block for Claude Code / Cursor / Cline. Agent-integration section showing per-client voice binding.

 ## [0.4.5] - 2026-04-22
 
 Second hotfix for the "offline mode is enabled" crash on model load. 0.4.4 reverted the inference-path offline guards but kept the same trap on the load path, so users who updated to 0.4.4 kept hitting the exact error the release was supposed to fix ([#526](https://github.com/jamiepine/voicebox/issues/526)). This release removes the load-path guards and patches the transformers tokenizer load to be robust to HuggingFace metadata failures at the source, so the class of bug can't recur.

-### Recording & Transcription
+### Global Dictation & Voice Input
 
-- In-app recording with waveform visualization
+The other half of the voice I/O loop. Hold a hotkey anywhere on your system, speak, release — the transcript pastes into the focused text field. Or hit the mic on any Voicebox text input and dictate directly into the app.
-- System audio capture (macOS and Windows)
+
-- Automatic transcription powered by Whisper (including Whisper Turbo)
+- **Global hotkey** — hold-to-speak or tap-to-toggle, configurable
-- Export recordings in multiple formats
+- **Target-aware paste** — accessibility-verified injection into text fields, atomic clipboard save/restore so your clipboard isn't clobbered
+- **In-app mic button** on every Voicebox text field — generation form, profile descriptions, story titles, anywhere you'd type
+- **Streaming transcription** via `/transcribe/stream` WebSocket — partial transcripts land as you speak
+- **LLM refinement** — optional cleanup of ums, stutters, and false starts before paste
+
+### Multi-Engine STT
+
+Four STT engines with different strengths, switchable per-capture:
+
+| Engine             | Languages | Strengths                                                           |
+| ------------------ | --------- | ------------------------------------------------------------------- |
+| **Whisper**        | 99        | The default. Broad language support, mature, battle-tested          |
+| **Whisper Turbo**  | 99        | ~8x faster than Whisper large, minimal quality loss                 |
+| **Parakeet v3**    | 25        | Current quality leader for non-English local STT, very fast         |
+| **Qwen3-ASR 0.6B** | 50+       | Highest multilingual quality, int8 quantized for cross-platform use |
+
+### Captures
+
+Every dictation, in-app recording, and uploaded audio file lands in the Captures tab — original audio paired with transcript, always preserved.
+
+- **Replay, re-transcribe** with a different model, or edit the transcript inline
+- **Play as voice profile** — turn any capture into speech with a cloned voice, one click
+- **Promote to voice sample** — use a capture's audio + transcript as a reference sample for voice cloning
+- **Send to** — clipboard, file, webhook, MCP sink, or back into the generation pipeline
+- **Configurable retention** — keep everything or auto-expire old captures
+
+### Agent Voice Output
+
+Every agent gets a voice. One tool call and any MCP-aware agent can speak to you in a voice you've cloned — task completions, questions, notifications. The same pill that surfaces during dictation surfaces during agent speech, so you always see what's coming out of your machine.
+
+```ts
+// In any MCP-aware agent:
+await voicebox.speak({
+  text: "Deploy complete.",
+  profile: "Morgan",
+});
+```
+
+Also exposed as `POST /speak` for anything that doesn't speak MCP — ACP, A2A, shell scripts, custom harnesses.
+
+- **Bidirectional pill** — `recording`, `transcribing`, `refining`, `rest`, and `speaking` are all states of the same OS-level overlay
+- **Per-agent voice binding** — Claude Code in Morgan, Cursor in Scarlett, so you can tell which agent is talking without looking
+- **Always visible** — no silent background TTS; every agent-initiated speech surfaces the pill
+- **Global mute + per-source rate limits** — a panic button for runaway agents
+
+### Persona Loop
+
+One flow on top of `speak()`: STT → persona LLM → `speak(reply)`. Voice profiles gain optional personality metadata and default LLM behavior. End-to-end voice-to-voice with a cloned identity transforming the content, not just reading it.
+
+- **Local LLM** — Qwen 3.5 0.8B / 2B / 4B, same runtime as TTS (MLX on Apple Silicon, PyTorch elsewhere)
+- **Voice profile personas** — optional personality description and default LLM behavior per profile
+- **Pipeline-native** — STT → persona LLM → TTS is a preset, configurable like any other route
+- **Voice-to-voice ready** — when end-to-end speech LLMs (Moshi, GLM-4-Voice, Qwen2.5 Omni) land, they slot in as a single transform and the pipeline shape stays the same
+
+Use cases: agent dev loops (talk to Claude Code, hear it back in a cloned voice), interactive characters for games and narrative tools, speech assistance for people who can't speak in their original voice.
+
+### Pipeline Routing
+
+Every voice event in Voicebox flows through the same shape: **Source → Transforms → Sinks**. Build presets, share them, invoke them from shell scripts and agent harnesses.
+
+| Sources              | Transforms          | Sinks                       |
+| -------------------- | ------------------- | --------------------------- |
+| Global hotkey        | STT model           | Paste into focused field    |
+| In-app mic           | Refinement LLM      | Clipboard                   |
+| Long-form recorder   | Persona LLM         | File on disk                |
+| File drop            | Translation (later) | HTTP webhook                |
+| API call (WS / HTTP) |                     | **MCP server** (agent sink) |
+|                      |                     | TTS loopback (cloned voice) |
+
+Presets are addressable by ID via `POST /pipelines/{id}/run`. The MCP sink means Claude Code, Cursor, and Cline get voice I/O one checkbox away — no custom integration.

+"""
+Refinement sanity sweep — runs ten realistic raw transcripts through
+``/llm/generate`` (with the full refinement system prompt) and scores
+each output against a handful of deterministic heuristics so a person
+can eyeball quality at a glance.
+
+This is an interactive evaluation harness, not a pass/fail unit test:
+LLM output is non-deterministic and "correctness" for cleanup is
+subjective. The heuristics catch gross failures (prompt leaks,
+Whisper-loop echoes, the model answering a question instead of
+rewriting it) but a human still has to read the final column.
+
+Usage:
+    # Backend server must be running.
+    python backend/tests/test_refinement_samples.py
+
+    # Hit a non-default port (auto-detected via /health probe when omitted):
+    python backend/tests/test_refinement_samples.py --port 17493
+
+    # Only test one model size:
+    python backend/tests/test_refinement_samples.py --model 4B
+
+    # Dump JSON for diffing against a prior run:
+    python backend/tests/test_refinement_samples.py --json results.json

+# Voice I/O
+
+**Status:** Shipping — phases 1, 2, 4, 7 (macOS) complete · 3 partial · 5, 6, 7 (Windows/Linux), 8 pending
+**Touches:** backend, Tauri shell, frontend, a new native shim crate
+**Last reviewed:** 2026-04-21
+
+## Progress
+
+### Shipped
+
+**Phase 1 — Groundwork.** Audio tab retired from the sidebar; its device / channel
+config lives under Settings. Captures tab is live at `/captures` with no feature
+flag.
+
+**Phase 2 — Local LLM backend.** `LLMBackend` protocol alongside the existing
+TTS/STT backends. `qwen_llm_backend.py`, `services/llm.py`, `routes/llm.py`, and
+a shared model-download / cache pipeline. Qwen3 0.6B / 1.7B / 4B registered and
+user-selectable via `capture_settings.llm_model`.
+
+**Phase 4 — Captures tab.** List + detail view, source badges (dictation /
+recording / file), retranscribe, refine (flags + model resolved from a
+server-side `capture_settings` singleton), delete, and the Play-as-voice
+dropdown over every profile.
+
+### Partial
+
+**Phase 3 — In-app voice input.** `CapturesTab` dictates end-to-end via
+`useCaptureRecordingSession`, which the Phase 7 floating pill also consumes.
+Outstanding: a universal mic button on other text inputs (Generate form,
+profile descriptions, story titles, etc.), and the streaming
+`/transcribe/stream` WebSocket — today's flow is a single `POST /captures`
+with the complete audio blob.
+
+**Phase 7 — External dictation shell (macOS).** Both halves shipped on macOS.
+
+Hotkey half:
+
+- `tauri/src-tauri/src/chord_engine.rs` — pure state machine. Unit tests green.
+- `tauri/src-tauri/src/hotkey_monitor.rs` — `rdev`-based global listener on a
+  background thread, with `set_is_main_thread(false)` applied to sidestep the
+  macOS 14+ TSM crash ([Narsil/rdev#165](https://github.com/Narsil/rdev/issues/165)).
+  Right-hand-only defaults preserve left-hand Cmd+Option+I devtools.
+- Default bindings hardcoded: `Cmd+Option` (push-to-talk) and
+  `Cmd+Option+Space` (toggle-to-talk). The PTT → Toggle upgrade transition is
+  preserved — adding Space mid-hold promotes the session without interrupting
+  audio.
+- `DictateWindow` — transparent, always-on-top, borderless 420×64 webview
+  pre-created hidden at app setup. Shows on chord-start, hides on
+  capture-cycle completion. Error state on the pill auto-dismisses and
+  copies-to-clipboard on click.
+
+Paste half (macOS):
+
+- `clipboard.rs` — `NSPasteboard` snapshot that walks `pasteboardItems` and
+  copies every `(uti, bytes)` pair so multi-type content (images, styled
+  text, file refs) survives the round-trip. `save_clipboard`,
+  `write_text`, `restore_clipboard`, `current_change_count`.
+- `synthetic_keys.rs` — `CGEventPost` at the HID tap with the full four-event
+  Cmd+V sequence (Cmd down → V down w/ flag → V up w/ flag → Cmd up).
+- `focus_capture.rs` — `AXUIElementCreateSystemWide` +
+  `AXUIElementCopyAttributeValue(kAXFocusedUIElement)` +
+  `AXUIElementGetPid`, with the AX attribute key CFStrings built at
+  runtime because they're CFSTR macros, not linkable symbols.
+  `NSRunningApplication.activateWithOptions:` for re-activation.
+- `accessibility.rs` — `AXIsProcessTrusted` gate.
+- `paste_final_text` command — activate → 120 ms settle → save clip →
+  write text → ⌘V → 400 ms → restore. Skips when focus was in Voicebox
+  itself.
+- Focus rides the `dictate:start` event payload; `DictateWindow` holds the
+  snapshot in a ref and consume-once-nulls on paste so a late-arriving
+  refine from an earlier session can't misfire.
+- Dictation recording no longer hard-caps at 29 s — the limit still
+  applies to voice-profile reference clips.
+
+Outstanding: Windows `SendInput` / UIAutomation / `SetForegroundWindow`
+equivalents, Linux `uinput` / AT-SPI equivalents (and the Wayland story),
+first-run Accessibility prompt UI with deep-link to System Settings,
+direct-injection path for focus-was-inside-Voicebox (step 6 — dictating
+into our own Generate tab currently falls back to the capture list).
+
+### Not started
+
+- **Phase 5 — Agent voice output + persona loop.** No `/speak` endpoint, no
+  `voicebox.speak` MCP tool, no per-agent voice binding, no persona metadata
+  on profiles.
+- **Phase 6 — STT engine expansion.** Only Whisper (`mlx_backend.py`).
+  Parakeet v3, Qwen3-ASR, Kyutai — all unregistered.
+- **Phase 8 — Pipeline routing, sinks, long-form.** No preset primitive, no
+  MCP sink, no webhook sink, no dual-stream recorder, no summary transform.
+
+### Additionally landed (not explicit in the original plan)
+
+These fell out of the Phase 3/4/7 work but deserve their own mention:
+
+- **Server-authoritative settings.** Singleton `capture_settings` and
+  `generation_settings` tables. The client sends nothing but the audio; STT
+  model, refine flags, refine LLM, and the auto-refine flag are all resolved
+  server-side, so sibling Tauri webviews can't go stale.
+- **Backend audio normalisation.** `POST /captures` transcodes anything
+  librosa can decode (webm/opus, m4a, etc.) to WAV before handing it to
+  whisper, side-stepping miniaudio's format gaps inside mlx-audio.
+- **Short-recording guard.** Sub-300 ms blobs short-circuit client-side so a
+  fumbled chord tap never uploads an empty webm.
+- **Refinement prompt.** Rewritten with firmer anti-chatbot framing and
+  inline examples covering multi-sentence preservation and self-correction.
+
+### Near-term outstanding
+
+Called out in recent sessions but not yet in a phase:
+
+- **Configurable chord bindings.** Pass 2 of the hotkey work — persist
+  `push_to_talk_chord` / `toggle_to_talk_chord` in `capture_settings`,
+  surface a chord-picker UI in `CapturesPage`, and wire a Tauri
+  `update_chord_bindings` command so `HotkeyMonitor::update_bindings` picks
+  up user changes live.
+- **Generate-tab empty-state explainer.** The parallel aside to the Captures
+  explainer described in *Product surface → Parallel explainer on the
+  Generate tab*. Lands alongside Phase 3's universal mic button so both tabs
+  feel symmetric.
+
+## Overview
+
+Voicebox ships the output half of a voice I/O loop: clone a voice, generate
+speech, apply effects, compose multi-voice projects. The input half — speech to
+text, dictation, routing — exists today as a single Whisper model wired into the
+Recording & Transcription panel. This doc proposes making voice *input* a
+first-class pillar: more STT engines, a dictation shell (global hotkey, audio
+capture, paste, streaming), a local LLM backend, and a user-configurable
+pipeline from captured audio to whatever the user wants to do with it.
+
+Positioning is the key move. **Voicebox becomes the local voice I/O layer for
+humans and AI agents** — a local alternative to cloud dictation tools, with the
+differentiator that we also do TTS and voice cloning. The same app that
+captures your voice can generate a response in any voice profile you've
+cloned. "Anything voice is Voicebox."
+
+### Positioning shift
+
+Before this plan, Voicebox was **"the open-source AI voice cloning studio."**
+Cloning was the headline capability.
+
+After this plan, Voicebox is **"the open-source AI voice studio."** Cloning is
+one capability in a broader category that now spans input (STT, dictation),
+intelligence (local LLM, refinement, persona), output (TTS, cloning, effects,
+Stories), and routing. The word "cloning" drops out of the top-line descriptor
+because it's become a feature rather than the thesis.
+
+### Competitive frame
+
+Voicebox ends up covering the territory of two separately-funded, separately
+branded cloud incumbents that operate on opposite sides of the same voice I/O
+loop:
+
+- **ElevenLabs** (~$3B+): voice cloning and TTS — the "agents speak" side
+- **WisprFlow** (~$70M raised): voice dictation for agents and power users —
+  the "users talk" side
+
+Both are cloud-only. Voicebox becomes the only local alternative to either,
+running in one app, with a single model directory and LLM shared between input
+and output. That bridging — dictation → LLM → TTS with a cloned voice in the
+middle — is the thing no single incumbent can match, because neither has the
+other half.
+
+### Launch-time copy tasks
+
+These are not engineering tasks but should ride the Phase 4 ship so marketing
+and positioning stay in sync with the product.
+
+- **README.md** — drop "cloning" from the top-line descriptor. Add a section
+  that explicitly frames Voicebox as "the open-source local alternative to
+  WisprFlow and ElevenLabs." Competitive framing belongs in the README and on
+  the landing page — not in-app (reads as defensive).
+- **voicebox.sh landing page** — same positioning shift.
+- **GitHub About / repo topics** — swap "voice-cloning" or similar tags for
+  broader "voice-io," "local-tts," "local-stt," etc.
+- **Release notes** — the Phase 4 launch note is the "we're now voice I/O" moment.
+
+## Why now
+
+- Cross-platform local dictation is an empty category. The tools people love
+  (Superwhisper, MacWhisper, Aiko) are macOS-only. WisprFlow and
+  Willow are cloud. Our Windows install base is the wedge — first-class Windows
+  support for a local dictation product is genuinely differentiated.
+- The `STTBackend` protocol already exists. The multi-engine registry pattern
+  shipped with TTS makes adding Parakeet v3 and Qwen3-ASR a days-not-weeks
+  effort on the backend side.
+- The **persona loop** — speak to an agent, have it reply in a cloned voice —
+  is a feature only we can ship. Nobody with a dictation product has TTS; nobody
+  with a TTS product has good dictation. The full duplex is ours.
+- Agent harnesses already pipe Voicebox TTS into their stacks. Giving those
+  users STT from the same app closes the loop and makes Voicebox the default
+  voice I/O layer for the agentic dev-tool crowd.
+- **Typing a 2,000-character TTS script is user-hostile.** The most immediate
+  internal win is dictating directly into Voicebox's own generation form —
+  speak the script, generate the voice. This dogfoods the whole STT pipeline
+  without touching a single OS-level API.
+- **Voice-to-voice models are landing.** Moshi (Kyutai), GLM-4-Voice, Qwen2.5
+  Omni, Mini-Omni, Sesame CSM, Spirit LM (Meta) — end-to-end speech LLMs that
+  take audio in and emit audio out are a near-term reality. The pipeline we're
+  building today is the scaffolding they slot into tomorrow.
+
+## Non-goals
+
+- Cloud fallback or "bring your own API key" STT/LLM. Local is the product.
+- A separate tray-only dictation app. We extend Voicebox, not fork it.
+- Replacing the Stories editor with a notes layout. Long-form capture is a
+  preset on top of the pipeline, not a new product surface.
+- Real-time translation UI. It can exist as a transform later, but it's not in
+  this plan.
+- Full agent orchestration. We provide the voice rails; the agent lives
+  elsewhere and talks to us via the developer API.
+
+## Architecture
+
+### Three new backend concepts
+
+**1. Expanded STT registry.** The existing `STTBackend` protocol abstracts
+Whisper today. Add:
+
+- **Parakeet v3** — 25 languages, very fast, the current quality leader for
+  non-English local STT. Python path via `nemo_toolkit` or `transformers`.
+- **Qwen3-ASR 0.6B int8** — 50+ languages, highest multilingual quality,
+  cross-platform via `transformers`.
+- **Kyutai ASR** *(optional)* — streaming-first, small, CPU-friendly. Fills the
+  "CPU-only laptop" tier.
+
+All register via `ModelConfig` and use the same download, cache, and model
+management UI we already have for TTS. Zero special-casing.
+
+**2. `LLMBackend` protocol.** Mirror of `TTSBackend` / `STTBackend`. First
+implementations are Qwen3 0.6B / 1.7B / 4B running on the same PyTorch + MLX
+infrastructure we already run. One runtime, one model cache, one GPU-memory
+story.
+
+Why not `llama.cpp` or `ollama`: we already have the dependency surface and the
+model download UX. A second runtime fragments cache directories and model-status
+UI. If CPU-only Windows latency becomes a problem we can revisit.
+
+**3. Streaming transcribe transport.** Add `/transcribe/stream` as a WebSocket
+endpoint alongside the existing HTTP `/transcribe`. Audio frames flow in,
+partial transcripts stream back. Same FastAPI process, same loaded models. This
+keeps dictation latency off the per-request JSON-encode critical path and lets
+us ship real-time partial transcripts later without a protocol change.
+
+### The pipeline abstraction
+
+Every captured audio event flows through the same shape:
+**Source → Transforms → Sink(s)**. Users configure presets that bind a source
+to a transform chain to one or more sinks.
+
+```
+Source                      Transform                    Sink
+──────────────────          ─────────────────            ─────────────────
+Hold to speak        ──┐    STT model                    Clipboard + paste
+Tap to toggle          │    Refinement LLM               Capture history
+Long-form recorder     ├──▶ Persona LLM              ──▶ File on disk
+File drop              │    Translation (later)          HTTP webhook
+API call (WS / HTTP) ──┘                                 MCP server sink
+                                                         TTS loopback (persona)
+                                                         Platform sinks (later)
+```
+
+`Source → Transform → Sink` is internal, dataflow-style vocabulary (same shape
+as Unix pipes, Apache Beam, Kafka) — not user-facing. The UI surface will use
+Voicebox-native language (see open questions).
+
+Concrete preset examples this shape enables:
+
+- **Dictation** — hold-to-speak → Parakeet v3 → light refinement → clipboard + paste + history
+- **Code prompt** — dedicated hotkey → Whisper Turbo → technical-vocab refinement → MCP sink for Claude Code
+- **Agent voice reply** — hold-to-speak → STT → persona LLM → TTS with cloned profile → system audio out
+- **Long-form capture** — dual-stream recorder → chunked STT → summary LLM → markdown file + history
+
+Every user-facing feature collapses into (source + transform chain + sinks).
+Meeting-style capture isn't a separate product; it's a preset. Competing tools
+hardcode integrations (Trello, Granola); we make routing user-configurable.
+
+### Native shim crate
+
+The parts Tauri doesn't handle cleanly, gathered in one Rust crate with a
+platform-agnostic API:
+
+- **Global hotkey with modifier-only support.** Tauri's `global-shortcut`
+  plugin requires full combos. We need "hold right-cmd" or "hold ctrl" as
+  primitives. On macOS this means a CGEventTap on a background thread with
+  polling fallback for dropped modifier events; on Windows a low-level keyboard
+  hook; on Linux X11 + libinput, with Wayland as a known gap.
+- **Focus introspection.** Query the frontmost app and its focused element via
+  OS accessibility APIs — `AXUIElement` on macOS, UIAutomation on Windows,
+  AT-SPI on Linux. Check the element's role to decide between a direct
+  injection, a clipboard + paste, and a clipboard-only fallback with a
+  notification. A blind paste that only "works when a text field happens to
+  be focused" is the easy default; we should make the decision deliberately.
+- **Simulated paste.** CGEvent on macOS, SendInput on Windows, uinput / ydotool
+  on Linux. Wayland is the hard case and needs explicit handling.
+- **Atomic clipboard save/restore.** Save *all* items and *all* MIME
+  representations before writing our transcript, restore atomically after
+  paste. Pasting a transcript shouldn't clobber a user's in-progress rich-media
+  clipboard.
+- **Frontmost-window context capture** *(later).* macOS Vision, Windows OCR,
+  Linux tesseract. Optional feature to feed the refinement LLM disambiguation
+  hints from the window being pasted into.
+
+Main process owns this crate. Webview never sees platform differences.
+
+### Target-aware delivery
+
+The paste sink adapts to what's in focus. This is a single sink type with
+branching behavior, not four separate sinks.
+
+| Target | Delivery strategy |
+|---|---|
+| Focused text field inside Voicebox | Direct React state update via event. No clipboard involved. |
+| Focused text field in another app | Accessibility-verified paste: save clipboard, write transcript, simulate paste, restore clipboard. |
+| No text focus detected | Clipboard only, toast notification ("Transcript copied — no text field focused"). |
+| Platform-specific special cases (terminal apps, specific editors) | Per-app overrides where the generic path misbehaves. |
+
+### Where each concern lives
+
+| Concern | Layer |
+|---|---|
+| STT / LLM / TTS inference | Python backend |
+| Model downloads, progress, cache | Python backend |
+| Pipeline runner (orchestrates transforms and sinks) | Python backend |
+| Audio capture from mic / system audio | Rust (Tauri side) |
+| Audio streaming over WebSocket to backend | Rust |
+| Global hotkey capture | Rust (native shim crate) |
+| Paste simulation, clipboard save/restore | Rust (native shim crate) |
+| Pipeline preset UI, capture history, settings | React |
+
+Model work in Python. OS work in Rust. User config in React.
+
+## Product surface
+
+### A new tab (and a sidebar reshuffle)
+
+The current sidebar is `Generate · Stories · Voices · Effects · Audio · Models ·
+Settings`. The existing Audio tab is output-device and channel routing
+config — infrastructure, not a creative workspace — and the Settings page
+already has a sub-tab pattern (`ServerSettings/`: Connection, Models, GPU,
+Update) that fits it naturally.
+
+**Move Audio to a Settings sub-tab. Reclaim the sidebar slot for voice input.**
+
+The new tab shows recent captures (audio + transcript paired), active presets,
+dictation settings, model pickers for STT and LLM. Exact name is an open
+question.
+
+**Sidebar placement:** Captures sits at position 3, directly under Stories and
+above Voices. Creates an "input voice / output voice" adjacency — captured
+speech is one slot away from the voices you can play it back through, which
+mirrors the Phase 4 "Play as voice" feature's mental model. Full order:
+Generate · Stories · Captures · Voices · Effects · Models · Settings.
+
+### Parallel explainer on the Generate tab
+
+The Captures settings page gets a "What's different" aside that introduces
+Voicebox's dictation story. The Generate tab deserves a parallel — first-time
+users need to be told what voice generation is *for* in a post-Voice-I/O
+world, not just handed a text field.
+
+Shape: an **empty-state card** rendered in the Generate tab when there's no
+generation history yet, disappearing once the user has generated anything.
+Teaches without claiming permanent real estate. Parallel bullets to the
+Captures aside so the two tabs feel like two sides of one product:
+
+- **Clone any voice in seconds** — a short sample is enough
+- **Seven engines, 23 languages** — creative range, not a single model
+- **Agent-ready** — REST + WebSocket API, one checkbox away from giving any
+  AI agent a voice
+
+This lands in Phase 4 alongside the Captures tab, for visual and thematic
+symmetry. Not a persistent sidebar — the Generate tab is a workspace and
+should reclaim its space once the user is producing work.
+
+### Archival by default
+
+Every capture saves the original audio alongside the final transcript in a
+pattern that mirrors `data/generations/`. Optional retention setting. Free for
+us — the storage and UI patterns exist today for generations.
+
+### Developer API, day one
+
+The WebSocket transcribe endpoint is a first-class public API, documented
+alongside `/generate`. Pipeline presets are addressable by ID via
+`/pipelines/{id}/run` so agent harnesses and shell scripts can invoke
+user-configured flows. An MCP server sink ships built-in, so integrations with
+Claude Code, Cursor, Cline, etc. are one checkbox rather than a custom build.
+
+### Agent voice output
+
+Dictation is one half of the loop — user speaks, agent listens. The other half
+— agent speaks, user hears — is equally load-bearing and deserves a
+first-class primitive rather than being buried as a TTS loopback sink or a
+consumer read-aloud button.
+
+The shape is a single new capability: any agent can call Voicebox to speak
+arbitrary text in a user-configured voice. The same pill that surfaces during
+dictation surfaces during agent speech, so the user always sees what's coming
+out of their machine.
+
+```
+MCP tool:  voicebox.speak({ text, profile?, style? })
+REST:      POST /speak { text, profile_id?, style? }
+```
+
+Both accept an optional voice profile (defaults to the user's configured
+default), an optional delivery-style string for engines that support it, play
+audio through system output, and surface the pill in a `speaking` state.
+
+**Key design points:**
+
+- **Pill is bidirectional.** States expand from `recording / transcribing /
+  refining / rest` to include `speaking` — voice profile name, waveform in
+  the profile's color, visible duration. Same floating surface for both
+  directions so users have one mental model.
+- **Visibility is mandatory.** Silent background TTS is a trust hazard. Every
+  agent-initiated `speak()` surfaces the pill. No headless "TTS daemon" mode.
+- **Per-source voice policy.** Settings let users bind specific MCP clients or
+  API keys to specific voice profiles — Claude Code in "Morgan," Cursor in
+  "Scarlett" — so users can tell which agent is talking without looking.
+- **Mute + rate limits.** One-toggle mute for all agent speech. Per-source
+  rate limits prevent a runaway agent from monologuing.
+
+This primitive is what makes "Voicebox as voice layer for every agent on your
+machine" a concrete shipping capability rather than marketing language. MCP,
+ACP, and A2A integrations all slot into it — none of those agent protocols
+need to know anything about TTS models, GPU placement, or voice profiles.
+They call `speak()`.
+
+**Relationship to the persona loop.** The persona loop below is *one* use of
+`speak()` — STT → LLM → `speak(llm_reply)`. Other uses skip STT entirely: a
+long-running task announcing completion, a notification, an agent proactively
+asking the user a question. The primitive is deliberately simpler than the
+persona loop so it can serve both flows from the same API.
+
+### Relationship to voice profile samples
+
+A capture and a voice profile sample both hold `audio + text`, so there's an
+obvious temptation to unify them. Don't. The metadata and lifecycle
+differences are real:
+
+| | Capture | Voice profile sample |
+|---|---|---|
+| Profile association | Standalone | Bound to one profile |
+| Text field | Raw transcript + optional LLM-refined version | Exact `reference_text` only |
+| LLM refinement | Often applied | Must not be applied — the reference text must match the audio verbatim or cloning breaks |
+| Volume | Dozens per day | ~5 per profile, semi-permanent |
+| Typical content | Whatever the user said | Often scripted phrases for cloning |
+
+A unified table would mean nullable `profile_id`, nullable `refined_transcript`,
+nullable `reference_text` — a fat row that means different things in different
+states. Not worth the complexity.
+
+**What to ship instead: a one-way promote action.** Capture → Sample, zero
+data-model churn. Thin endpoint:
+
+```
+POST /profiles/{id}/samples/from-capture/{capture_id}
+```
+
+Reads the capture's audio path and raw transcript, calls the existing
+`add_sample()` service with `reference_text` pre-filled from the transcript,
+lets the user edit the reference text in a dialog before saving (transcripts
+are usually 90% right but cloning wants 100%). The capture stays in the
+Captures tab untouched — the sample is a copy, not a move.
+
+UI hook: the Captures tab's Send-to menu gains a **"Use as voice sample…"**
+option that opens a profile picker (with "+ New voice" for cold starts) and a
+reference-text confirm dialog.
+
+The inverse direction (sample → capture) we deliberately skip. Samples are
+often scripted phrases used for cloning and they'd clutter the Captures list
+without adding value; also a subtle privacy surprise for users who don't
+expect their sample text browsable alongside real captures.
+
+**Audio storage deduplication is a later optimization.** Today a promoted
+capture duplicates the audio file on disk. That's fine. Content-addressable
+storage (`data/audio/<sha256>.wav` with refcounting) can come in Phase 8 as
+housekeeping — it'd let a capture and a sample share one underlying file, but
+it's not user-visible and not necessary to ship the promote flow.
+
+### The persona loop
+
+One flow on top of the `speak()` primitive: STT → persona LLM →
+`speak(llm_reply)`. Voice profiles gain optional metadata — a natural-language
+personality description and default LLM behavior. The LLM runs text through
+the profile's voice context, then `speak()` generates TTS with the cloned
+profile. End-to-end voice-to-voice with a cloned identity transforming the
+content, not just reading it.
+
+Use cases this unlocks:
+
+- Agents that respond to spoken input in a specific voice
+- Interactive character experiences (games, narrative tools, accessibility)
+- Speech assistance for people who can't speak in their original voice
+
+The shape — STT + LLM + TTS — also stages us for end-to-end speech LLMs which
+collapse all three into one transform. See *Voice-to-voice readiness* below.
+
+### Voice-to-voice readiness
+
+The STT → LLM → TTS chain that powers the persona loop is a staged approximation
+of voice-to-voice. A real end-to-end speech LLM (Moshi, GLM-4-Voice, Qwen2.5
+Omni, Mini-Omni, Sesame CSM) replaces the three middle boxes with a single
+fused transform: audio in, audio out, no text in between. The pipeline shape
+accommodates this natively — register the model as a single `LLMBackend` (or
+a new `SpeechLLMBackend` if the protocol needs to differ), expose it as a
+transform type, and the same sinks work unchanged.
+
+Framing this plan as "voice-to-voice scaffolding, with today's models as the
+staged fallback" is a strong pitch for agent-harness users who are already
+tracking these models.
+
+## Open questions
+
+1. **Tab name.** Leaning **Captures** — neutral, extensible across dictation,
+   long-form recordings, and uploaded audio without repainting the tab later.
+   "Dictations" is narrower (office-productivity coded, doesn't fit meeting
+   recordings). "Notes" is the wrong mental model — nobody opens Voicebox to
+   write notes. "Transcriptions" is flat.
+2. **Refinement vocabulary.** The LLM-post-STT step needs a user-facing name.
+   "Refine," "polish," "rewrite," "smart edit" are candidates. "Refinement" in
+   this doc as a placeholder only.
+3. **Preset primitive.** What do we call a user-configured pipeline? "Intent"
+   collides with the existing `instruct` field on TTS generation. "Flow" is
+   Zapier-coded. "Route" is too networking. Needs its own pass.
+4. **Persona metadata shape.** Does personality live directly on the voice
+   profile, or as a separate persona construct that wraps profile + LLM config?
+   The first is simpler; the second scales better if we later want multiple
+   personas per voice.
+5. **Long-form capture product surface.** Pure preset, or dedicated entry point
+   in the new tab? Leaning preset, but long-form is the feature that most
+   justifies its own landing page.
+6. **Hotkey primitive naming.** Hold-vs-tap needs Voicebox-native phrasing in
+   UI copy. Settings can still use industry-standard terms.
+
+## Ordered phases
+
+The v1 prototype deliberately skips the hardest parts of the long-term plan
+(native OS shim, global hotkeys, paste injection, new STT models). Everything
+in Phase 1–4 is in-process code using Whisper (which we already ship) and the
+existing model infra. No CGEvent taps, no SendInput, no clipboard timing.
+The usual OS-level sprawl of a dictation stack is exactly what we sidestep
+by starting in-app.
+
+### Phase 1 — Groundwork
+
+- Move the Audio tab into a Settings sub-tab (`ServerSettings/` gains one
+  more section). Audio is device/channel config, not a creative workspace.
+- Reserve the sidebar slot for the new Captures tab (name TBD but leaning
+  Captures — see open questions).
+- Gate the Captures tab behind a feature flag so we can merge to `main` and
+  iterate without shipping half-built UI to users.
+
+### Phase 2 — Local LLM backend
+
+`LLMBackend` protocol alongside `TTSBackend` / `STTBackend`. Register Qwen3
+0.6B / 1.7B / 4B via `ModelConfig`. Reuses the HF download path, cache
+directory, and model management UI. MLX (4-bit community quants) on Apple
+Silicon, PyTorch (transformers AutoModelForCausalLM) elsewhere, same as our
+TTS split.
+
+No new runtime. No `llama.cpp`, no `ollama`, no fragmented model cache.
+
+### Phase 3 — In-app voice input
+
+A universal mic button on every Voicebox text input. Hold, speak, release —
+text lands in the focused field via direct React state update. No OS APIs
+involved; Voicebox owns the input.
+
+Marquee use cases:
+
+- **Generation form.** Dictate a 2,000-character TTS script instead of typing
+  it. This alone justifies the feature.
+- **Voice profile descriptions.** Describe a voice's personality by speaking,
+  which then becomes the input for Phase 4's persona loop.
+- **Story titles, preset names, any free-text field.** Free reuse.
+
+Backend: add `/transcribe/stream` WebSocket endpoint. Audio frames in, partial
+transcripts out. Reuses the existing Whisper model in memory. Optionally routes
+through the LLM from Phase 2 for light refinement.
+
+### Phase 4 — Captures tab
+
+Graduates the tab out from behind the feature flag. Shows recent captures
+(audio + transcript pairs), lets the user replay, re-transcribe with a
+different model, edit the transcript, and send the output through the LLM.
+Archival is automatic — every capture saves audio alongside transcript.
+
+**Includes the "Play as voice profile" action.** This is the simplest version
+of the persona loop and it lands here for free — no LLM involved, no new
+backend endpoints, just a Captures-tab button that sends the transcript text
+to the existing `/generate` endpoint with a user-selected voice profile and
+plays the result. Category-defining differentiator from the v1 prototype
+onward: Superwhisper and WisprFlow cannot do this because they have no TTS. Voicebox can, with one day of frontend wiring.
+
+Keep it aggressively minimal on day one. A capture list, a detail view, a
+model picker, a Play-as-voice dropdown. Refinement prompt editing, correction
+dictionaries, per-source overrides — none of that ships here. They become
+Tier-2 work when someone actually asks for them.
+
+### Phase 5 — Agent voice output + persona loop
+
+Two features that together make "Voicebox as the voice layer for every agent
+on your machine" a shipping reality:
+
+1. **`speak()` primitive.** New `POST /speak` endpoint and `voicebox.speak`
+   MCP tool. Any agent calls Voicebox to speak arbitrary text in a
+   user-configured voice; the pill surfaces in a `speaking` state. Settings
+   UI for default voice, per-agent voice binding (Claude Code → Morgan,
+   Cursor → Scarlett), and a global mute.
+2. **Persona loop.** Extends `speak()` with an LLM step — STT → persona LLM
+   → `speak(llm_reply)`. Voice profiles gain optional personality metadata
+   and default LLM behavior. End-to-end voice-to-voice with a cloned
+   identity transforming the content, not just reading it.
+
+Phase 4 demoed the user-initiated direction of the loop (Play as voice). This
+phase ships the *agent*-initiated direction, which is the category-defining
+capability and the pitch that lands with agent-harness users. The persona
+loop is one flow on top of the `speak()` primitive — notifications, proactive
+agent questions, and task-completion announcements all use `speak()` directly
+without the LLM in the middle.
+
+Launchable headline moment for the "local voice I/O" positioning.
+
+### Phase 6 — STT engine expansion
+
+Parakeet v3 and Qwen3-ASR register as additional `STTBackend` implementations.
+Optional: Kyutai ASR. Multilingual coverage upgrades (50+ languages). Whisper
+stays as the sensible default.
+
+Deferred to here because Whisper is already good enough for v1 and the model
+picker UI exists. Adding rows to it doesn't change the product shape.
+
+### Phase 7 — External dictation shell
+
+Native shim crate (global hotkey with modifier-only support, focus
+introspection via OS accessibility APIs, paste simulation, atomic clipboard
+save/restore). Tauri-side audio capture streams to the same WebSocket endpoint
+Phase 3 already ships. Paste sink with target-aware delivery.
+
+This is the feel-good phase. It's also the riskiest: paste timing, hotkey
+reliability, and cross-platform focus detection are all engineering problems
+that have to be nailed or the product doesn't work. Phase 3's success derisks
+the backend plumbing before we start it.
+
+### Phase 8 — Pipeline routing, sinks, long-form
+
+Multiple source types, user-configurable transform chains, multiple sinks per
+preset. MCP server sink (the agent-harness play). HTTP webhook sink. File
+sink. Developer-facing `/pipelines/{id}/run` endpoint. Preset editor UI in
+the Captures tab.
+
+Dual-stream recorder (mic + system audio) as a source type. Chunked STT
+transform with overlap-based deduplication. Summary LLM transform. Long-form
+capture becomes a preset, not a new tab.
+
+Platform-specific sinks (Apple Notes on macOS, Obsidian, etc.) as opt-in
+integrations behind the generic sink interface.
+
+## Architectural prerequisites
+
+Two pieces of existing `docs/PROJECT_STATUS.md` work become load-bearing here:
+
+- **Platform support tiers** (#420, PR #465). Native shim capabilities vary by
+  platform — Wayland paste is worse than X11, Windows system-audio capture has
+  edge cases, frontmost-window OCR is platform-gated. Tier definitions let us
+  ship confidently with honest user-facing expectations.
+- **Platform gating on `ModelConfig`** (bottleneck #6 in PROJECT_STATUS).
+  Parakeet's Core ML path is Apple-only; the PyTorch path is Windows/Linux.
+  Same gating mechanism that currently blocks shipping VoxCPM.
+
+Neither needs to complete before Phase 1, but both should complete before
+Phase 4 when user-configurable pipelines surface the differences to end users.

+//! Snapshot / write / restore helpers around the system clipboard.
+//!
+//! Used by the auto-paste flow: before synthesising the paste accelerator
+//! into a foreign app we need to (1) remember what the user had on the
+//! clipboard, (2) stage our transcribed text, (3) paste, (4) put the
+//! original contents back. Missing step 4 turns every dictation into a
+//! silent clipboard-stomp.
+//!
+//! On **macOS** the snapshot walks `NSPasteboard.pasteboardItems` and
+//! copies every `(UTI, data)` pair into an owned `Vec<u8>`, so restore
+//! rebuilds the full multi-type payload — not just the plain-text
+//! fallback. Images, styled text, file-reference lists all survive the
+//! round-trip.
+//!
+//! On **Windows** the snapshot walks `EnumClipboardFormats` and copies the
+//! HGLOBAL payload for every advertised format. GDI-handle formats (DIB
+//! bitmap, metafile, enhanced metafile, palette), owner-display variants,
+//! and the private-/GDI-object format ranges are skipped — those can't be
+//! round-tripped across processes without synthesising the underlying
+//! kernel/GDI objects, which isn't worth the complexity for a dictation
+//! clipboard guard. CF_UNICODETEXT, CF_HDROP, CF_DIB (bitmap data in
+//! memory, not a handle), CF_DIBV5, and every registered format (HTML
+//! Format, Rich Text Format, FileGroupDescriptor, etc.) all survive.
+//!
+//! On **macOS** every entry point manages its own `NSAutoreleasePool`
+//! because the Tauri command runtime threads don't have one by default —
+//! without it, every autoreleased `NSString` / `NSData` we touch would
+//! leak for the life of the process. On Windows, HGLOBAL ownership

+//!
+//! - **macOS** — Cmd down, V down with Cmd flag, V up with Cmd flag, Cmd
+//!   up via `CGEventPost` at `kCGHIDEventTap`. Accessibility permission is
+//!   load-bearing: without it the system swallows the events silently, so

+//!   windows when we run non-elevated — nothing we can do short of also
+//!   running elevated.
+//!
+//! The virtual keycode used for V is `kVK_ANSI_V` (9) on macOS and `VK_V`
+//! (0x56) on Windows. Both are layout-dependent — they mean "the physical
