- Catalog: 3.3 MB zipformer keyword-spotting model (kws-en).
- shared/keywords: BPE encoding of wake phrases (SentencePiece table for common words,
greedy longest-match fallback over the model vocabulary) and keywords file builder.
- Worker: KeywordSpotter stream fed with 16-bit PCM, detections pushed as unsolicited
messages; engine derives the keywords file, maps sensitivity to threshold/score,
forwards detections to the renderer and re-arms after a worker restart.
- Renderer: WakeListener keeps one microphone stream, batches 256 ms frames to the
spotter and captures the command on the same stream after detection (pre-roll, VAD),
then resumes spotting; the wake word also interrupts speech. Settings: wake mode
(off / always-on / transcript filter), keyword, sensitivity, status and one-click
model download; HUD caption shows the active keyword.
- Validated: detection in the worker (fork) and through the real Electron IPC path on
Kokoro audio, no false positive on an English recording; 23 unit tests.

Electron main
- utility-process channel: sherpa output copied into V8 buffers (Electron rejects external
buffers), audio exchanged as base64; worker restart on timeout, identity-safe exit handling,
deterministic native unload by restart
- webhook: loopback by default without secret, UTF-8-safe body assembly, clean restart, port validation
- files IPC: realpath-based root check, openPath allow-list (reveal-only outside document folders),
Windows reserved names; store: debounced async atomic writes with backup of corrupt files;
logger: streaming writes with rotation; log message size cap
- HTTP stream proxy: socket released on idle timeout / renderer destroyed, id validation
- model manager: inactivity timeout, retrying rm/rename (Windows locks), engine stopped before
replacing a model; WAV decoder handles float/24-bit; IPC payload validation
- window: opaque rounded window on Windows, navigation lock-down, visibility events;
Ctrl+Alt+Escape instead of the Task Manager shortcut; single-instance guard; EVEFLOW_USER_DATA
Voice pipeline
- abort semantics (SendHandle.aborted), abort before the stream opens, session id prefixes per transport
- hands-free re-arm after replies without speech, start/stop race, no chime on auto re-arm,
no silence shipped to STT (400 ms pre-roll), no transcription of empty manual stops
- TTS: bounded prefetch, cancellable segments, non-interrupting notices, volume applied at play time
- SSE CRLF split, usage in chat completions, finish_reason length, phonetic regex hoisted
HUD
- core renderer: no canvas shadows, cached colours, reusable spectrum buffer, theme read on change,
30 fps idle, stops when the window is hidden; ping flashes on send / tool / speech
- deltas coalesced per animation frame; stable auto-scroll; narrow selectors everywhere
- bundled fonts (offline), reduce-motion fix, error toasts, ops drawer below 1180 px,
interim transcript and first-token latency in the core caption, Ctrl+K, dialog semantics,
switch/aria roles, compact widget cleanup, Whisper small recommended for French
- docs/ROADMAP.md: audit results, e2e results and the plan towards a real JARVIS

- electron/voice: model catalog (Whisper base/small/turbo, SenseVoice, Kokoro v1.0,
Piper fr), streaming tar.bz2 downloader with progress, sherpa-onnx worker running in
an Electron utilityProcess (transcribe / synthesize / status / unload), IPC + bridge.
- Renderer: 'local' providers for STT and TTS, Settings → Modèles locaux (download,
progress, delete, activate), speaker selection, hands-free wake word with a tolerant
matcher (accents, punctuation, edit distance) and attention window after a bare wake word.
- Packaging: native addon and worker unpacked from the asar; release 2.1.0.
Validated on Linux: Kokoro (fr) → Whisper base round trip, Piper (fr) → Whisper round trip.

Complete rewrite of the application:
- Toolchain: Electron 44, Vite 8, React 19, TypeScript 5.9, Zustand, Vitest;
main process rewritten in TypeScript (electron/), typed IPC contract (shared/),
sandboxed renderer with webSecurity on and an HTTP/SSE proxy in the main process.
- Voice: AudioWorklet microphone capture at 16 kHz with adaptive energy VAD and
auto-stop, WAV encoder, OpenAI-compatible STT, TTS queue with sentence-level
streaming, prefetch and Web Audio playback feeding an analyser; hands-free mode,
global push-to-talk hotkey, system-voice fallback.
- Hermes: full API client (capabilities, health, models, skills, toolsets,
sessions, jobs) with automatic transport selection: runs API (SSE lifecycle,
approvals, steer, stop) > sessions stream > chat completions with local tools;
tolerant event normalisation; webhook receiver hardened (secret, size limit).
- UI: JARVIS arc-reactor core on Canvas 2D reacting to the real audio signal,
holographic HUD layout (transcript, core, Hermes ops panel with tools/crons/
skills/sessions/link tabs, telemetry), settings drawer, approval modals,
compact floating widget, four themes, tray icon and global shortcuts.
- Removed the 3D Eve robot, three.js and legacy assets; migrated 1.x settings.
