- Remove the authless "sole connected phone" fallback and SB_REQUIRE_MCP_AUTH:
an unauthenticated request no longer reaches whichever phone is online alone.
- Mcp-Session-Id is no longer a credential; the Bearer token is checked on
every request (MCP auth spec).
- Refresh tokens live 90 days (was 30, equal to the access token, so they
were always dead when first needed).
- A rejected refresh no longer counts toward the IP ban: a client with an
expired token was retrying into a self-renewing ban on its own IP.
- 401s carry the RFC 9728 WWW-Authenticate discovery header.
Ported from the Android edition's server:
- JSON-RPC notifications (requests without an id, e.g.
notifications/initialized) now get the bare HTTP 202 the MCP spec
requires instead of a malformed JSON-RPC error response, which strict
clients rejected.
- initialize echoes the client's requested protocolVersion when it is a
version we support (2024-11-05 / 2025-03-26 / 2025-06-18) instead of
always claiming 2025-03-26.

Publishes server work that shipped in the Android edition but never made
it to this repo:
- Full OAuth 2.0 flow (discovery metadata, dynamic client registration,
authorize + token endpoints) so claude.ai remote connectors and the
Android app can authenticate per-user instead of relying on the
sole-phone fallback.
- Safety governor: server-side heat model (intensity x time) with
automatic cooldown, per-user overrides via GET/POST /safety/config,
and governor state piggybacked on heartbeat pings so relay clients
can display it.
- SB_REQUIRE_MCP_AUTH env flag for multi-user deployments (disables the
unauthenticated sole-phone fallback).
- requirements-phone.txt and .env.example documenting the new knobs.
