The engine now ships an MCP server, a toolset registry and skill assets --
measured against a live editor rather than read about. Building a second
transport beside it is not a contest this project can win.
ADR-0001 is narrowed, not withdrawn. Its liveness reasoning survives intact:
process over file, tools that vanish honestly, recovery without a restart.
Three mechanisms are dropped (own JSON-RPC server, UDP-broadcast discovery, own
heartbeat) and discovery becomes a probe of the documented endpoint, which the
measurement showed gives a fast negative -- HTTP 404 with a routing error body,
no hang. That is the property the PID file could not provide.
Two layers stay ours: a server that runs without the engine, and tools that run
in a live game outside the editor, the layer the registry's editor-only
declaration leaves uncovered.
The load-bearing claim is flagged as not yet attempted: a runtime tool answering
in a packaged build. Until that runs it is derived, not measured.
