Unreleased

Fixed

• Disabling the governor now disables the governor. enabled gated only Governor.check() — the enforcement call. The heat model kept integrating on every heartbeat, the state kept riding along on heartbeat pings, and list_devices kept appending a heat/cooldown footer. With the governor switched off, a session could still surface ⚠ Governor: COOLDOWN and transition the phone's own state machine to COOLDOWN while nothing was being blocked at all — a disabled safety layer announcing a stop it would never enforce. tick() now returns early when disabled and clears any state carried over from before the toggle; to_dict() reports enabled: false with zeroed values; the list_devices footer is omitted entirely.
• Timed commands no longer accumulate heat forever. current_intensity was cleared only by record_stop(), which has three callers: an explicit stop, a phone-initiated emergency stop, and the dead man's switch. A pattern that ended on its own declared duration never told the server, so the heat model went on integrating at the last commanded intensity against hardware that had already stopped — indefinitely. Commands now carry their duration into record_command() and the intensity expires when it lapses. duration: 0 still means "runs until an explicit stop" and stays sticky. For escalate, the expiry is duration + hold_seconds, and only when hold_seconds > 0 — with hold_seconds: 0 it holds at peak indefinitely by contract.

Added

• tests/verify_governor.py — offline verification of the heat model: the disabled path, timed-command expiry, and the enabled-path invariants (cooldown trigger, cooldown exit on both heat and time, idle dissipation). Pure logic, no server or hardware. python tests/verify_governor.py
• enabled is now included in the governor state dict, so heartbeat consumers and /safety/status can tell a quiet governor from an absent one. Existing phone clients read heartbeat fields by key lookup and ignore unknown ones, so no client update is required.

v1.1 — 2026-07-07

This release brings the remote server up to date with everything that shipped in the Android edition since March, plus fixes found while porting. If you run a server from an older clone, rebuild the Docker image (docker-compose build --no-cache) and update your relay client — both sides changed.

Added

• OAuth 2.0 support. Full flow for claude.ai custom connectors: discovery metadata, dynamic client registration, a login page at /oauth/authorize, and a token endpoint. Each user signs in with their own account — no more sharing one token or relying on the single-phone fallback. The fallback still works for single-user servers and can be disabled with SB_REQUIRE_MCP_AUTH=true.
• Safety governor. Server-side heat model (intensity × time) that forces a cooldown when a session runs hot for too long. Server defaults via SB_GOVERNOR_* env vars, per-user overrides via GET/POST /safety/config, current state surfaced in list_devices and piggybacked on heartbeat pings.
• feature_index on every output and pattern tool. Multi-motor devices (Lovense Edge, Dolce, …) can now have each motor driven independently. Implemented in both relay clients; a bad index returns a helpful error listing the valid ones.
• CHANGELOG.md, .env.example, .gitignore, .gitattributes.

Changed

• Neutral engineering terminology in tool schemas and devices.json, matching the Android edition. Content filters on some LLM platforms refused tools whose schemas contained explicit anatomical language; the reworded schemas work across providers. list_devices now also shows what each output channel does.
• Duplicate same-model devices get suffixed short names (lush, lush_2) instead of silently replacing each other.
• Relay clients no longer push an unsolicited device list after authenticating; the server requests a scan on connect and the scan response covers it.

Fixed

• MCP protocol compliance: JSON-RPC notifications (e.g. notifications/initialized) now get the bare 202 the spec requires instead of a malformed error, and initialize echoes the client's protocolVersion when supported. Fixes connection failures with strict clients.
• OAuth token endpoint 500'd when a client POSTed the token request as multipart/form-data (missing python-multipart dependency).
• governor_enabled now round-trips as a real JSON boolean; strict clients (the Android app) previously couldn't re-enable the governor after disabling it.
• Patterns with duration=0 silently did nothing. They now run until an explicit stop, matching plain commands.
• escalate hold contract: hold_seconds ≤ 0 holds at peak until stopped, > 0 auto-stops after the hold — and an error mid-ramp can no longer leave the device running at the last intensity it reached.
• Pattern collisions: starting a pattern cancels the previous pattern on that device (they used to fight over the actuator), and a direct command now supersedes a running pattern instead of being overwritten by it.
• Stale auto-stops: a duration auto-stop from an earlier command could fire minutes later and silently kill output a newer command had started. Auto-stops are now tracked per channel and cancelled when something newer takes over.
• Pattern timing now uses a monotonic clock; an NTP wall-clock jump could stretch, truncate, or instantly end a pattern.
• Repo hygiene: removed accidentally committed compiled bytecode (__pycache__) and a stray deploy tarball.

v1.0 — 2026-03-14

Initial public release: FastAPI relay server (MCP over HTTPS, JWT auth, rate limiting, dead man's switch), Windows/desktop relay client, and the Termux relay for Android.
