Replace the legacy terminal flow with a shared authenticated WebSocket
runtime used across web, desktop, relay, and mobile surfaces.
- introduce the v3 terminal protocol with scoped attachments, snapshots,
ordered output, bounded replay history, reconnects, and explicit lifecycle
- harden PTY creation, restart, resize, close, force-kill, idle cleanup,
shell selection, login mode, environment sanitization, and appearance sync
- add runtime-aware terminal APIs with relay authentication and Electron parity
- add a fullscreen mobile terminal workspace with touch scrolling,
long-press selection, safe-area controls, quick keys, and Ctrl/Alt input
- add terminal selection attachments, preview detection, project actions,
shell settings, and localized UI
- harden Ghostty rendering, resize recovery, Unicode handling, block
characters, line height, and stale-row behavior
- remove the obsolete terminal SSE path and update reverse-proxy guidance
- expand terminal runtime, transport, input, selection, and store coverage
- avoid duplicate web builds when preparing mobile assets in root CI builds
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
