Module subc 

subc daemon attach — transport edge.

When AFT is launched as aft --subc <connection-file>, it does NOT run the standalone NDJSON-over-stdin loop. Instead it connects to a running subc daemon over loopback TCP, authenticates with the pre-envelope HMAC handshake (subc-transport), then speaks the subc frame protocol (subc-protocol): ModuleHello → HelloAck (register as a tool provider), then a channel-0 control loop (Ping/Pong, RouteBind) plus route-channel tool calls.

Concurrency: subc routes tool calls through the executor. The tokio edge never dispatches against AppContext inline; per-actor executor lanes own the reader/mutator epoch, while a writer task serializes outbound frames.

SubcError

Functions

run_subc_mode

Entry point for aft --subc <connection-file>. Synchronous on the outside; owns an isolated current-thread tokio runtime for the async transport. Returns Err (fail-loud) on any connect/auth/protocol failure — we never fall back to the standalone loop, to avoid split-brain index state.

Type Aliases

DispatchFn

Sync command dispatch, passed in from main (the binary owns the command table). Invoked only inside executor jobs in subc mode.
