feat(dictation): transcribe after recording instead of live
Parakeet is an offline model trained on whole utterances, so re-decoding the growing buffer to animate a live transcript cost O(n^2) work for a result the final decode replaced. Sessions now decode once per committed segment, and the composer shows a scrolling waveform of the mic level instead of running text. Long dictations split at a pause once past 60s (hard cap 90s) instead of on a blind 15s timer, so cuts no longer land mid-word. Committed segments decode while the user is still speaking: a 185s dictation returns 4.1s after stop instead of 11.0s, with identical text (816 vs 817 words). Also fixes two ways the stream manager could silently drop transcribed audio. It now counts the commits it issued instead of trusting the session's echoed events, so a commit still in flight when the client finishes can no longer be left out of the final text. And segment byte/peak accounting is reset where the commit is issued rather than when the event arrives, which could mistake the tail of a dictation for silence and clear it. |

feat: add private relay for end-to-end-encrypted remote access (#2087)
Adds OpenChamber Relay — an opt-in way to reach an instance from a phone, browser, or another desktop from anywhere, with no open inbound ports, no tunnel, and no shared LAN. The instance dials outbound to a relay; all app traffic (HTTP, the event stream, terminal, dictation) is multiplexed and encrypted through a single connection per client, so the relay only ever forwards opaque ciphertext. Transport - End-to-end-encrypted channel over WebCrypto (ECDH P-256 -> HKDF -> AES-256-GCM) with a capability-negotiated handshake and a small HTTP/SSE/WebSocket multiplexing protocol. A byte-compatible JS host mirror is cross-checked by tests. - Host: outbound connection manager, per-client tunnel dispatcher to the local server over loopback, reuse of the existing instance identity key, and management routes. Disabled by default; explicit opt-in. - Client: plugs into the existing runtime layer (runtime-fetch/-url/-switch/ -auth, event pipeline, terminal, dictation) so features work over the relay unchanged; direct-URL and Electron realtime-proxy paths are untouched. Pairing & UX - Relay section in Settings -> Remote Instances (live status, QR/link pairing, revocation via the existing client-token list) and the mobile connect flow. - Frame batching and idle-gated keepalive keep tunnel message volume low without affecting streaming smoothness. Security - The tunnel is transport only; the server authenticates every tunneled request exactly as for a direct remote client. fragments only. The relay stores no keys, tokens, or payloads. Operability - The endpoint can be pinned to a self-hosted rel paired clients inherit it from the offer automatically. - Relay module DOCUMENTATION.md and a relay-trans invariants that future WebSocket/streaming changes must follow. The relay transport is complete and tested; the UI for enabling and pairing is gated behind openchamber_relay_gate and stays |

feat(voice): first-class voice input and local TTS across web, desktop, and mobile (#2018)
Complete rebuild of voice input on a server-authoritative streaming architecture, replacing the legacy Web Speech / whole-blob / WASM engines and the dead voice-agent layer (~4k lines removed). Speech-to-text (dictation): - Client streams 16 kHz mono PCM16 chunks over /api/dictation/ws with seq/ack ordering; buffered audio is retained and replayed on reconnect - Server transcribes and streams live partial transcripts back; segments auto-commit every ~15s with silence suppression and adaptive finalization timeouts - Local provider (default, zero config): sherpa-onnx models in a forked worker process — auto-download with progress, staged extraction with verification, corrupt-model auto-recovery, idle shutdown after 5 min - Model catalog with settings picker (accuracy/speed ratings, sizes, download/delete): Parakeet TDT v2 (English) and v3 (25 European languages, auto-detected), Whisper base and tiny (multilingual, light) - OpenAI-compatible provider for any Whisper endpoint - Composer overlay with live transcript, volume meter, timer, and cancel / insert / insert-and-send actions; failed transcriptions keep their audio for retry or accepting the partial text as-is - Configurable keyboard shortcut (default mod+alt+v) toggles dictation; Enter confirms and Escape cancels while recording - Overlay is pixel-aligned with the composer (measured footer height, matching paddings/typography/gaps) — no layout shift when toggling Text-to-speech: - Local Kokoro provider (English, 11 voices) synthesized in the same worker via /api/dictation/tts/speak, managed by the shared model pipeline; sentence-pipelined playback keeps time-to-first-audio at ~1 sentence regardless of message length, and stop cancels in-flight synthesis - Sanitizer keeps inline-code content (strips backticks only), reads interword slashes aloud, and removes only absolute file paths Settings: - Voice page unified: a single read-aloud toggle owns all playback options (the confusing "Enable Voice Mode" is gone); a new "Enable voice input" toggle (default on, persisted to settings.json) hides the composer mic entirely when disabled Mobile and transport: - iOS/Android microphone permissions added (dictation was previously impossible on mobile) - Fixed Android WebSocket upgrades: the Capacitor WebView origin (https://localhost) was missing from the packaged-client allowlist, 403-ing every WS connection — root cause of the old mobile SSE lock, which is now removed for all transports Security and conventions: - All HTTP routes sit behind the global /api auth gate; the WS upgrade explicitly validates the UI session and origin, with oc_url_token narrowly allowlisted and covered by tests; the dictation socket mints a fresh URL token before connecting - Routes register before the generic OpenCode proxy; the client goes through runtimeFetch/getRuntimeUrlResolver, and runtime switches reset the dictation socket - VS Code deliberately reports dictation as unavailable (no server process in that runtime) CI: workflow Node bumped 20 -> 22 to match the repo engines and fix better-sqlite3 installs broken by node-gyp@latest on Node 20. New dependency: sherpa-onnx-node (prebuilt N-API; macOS/Linux x64+arm64, Windows x64 — Windows-on-ARM falls back to the OpenAI-compatible provider) |
