Completes the request path for FLUID-WP-0003 T01-T03 and T05-T07. The
gateway resolves a revision, routes to the adapter process, and records
what happened, without ever depending on the control plane to serve.
Three behaviours carry tests because the architecture rests on them:
Emit never blocks against a stalled sink (Blueprint 34.2), the gateway
keeps serving after control-plane loss (invariant 2), and backend
internals do not leak into error responses (5.7).
The connector retries only idempotent methods, so a slow adapter cannot
cause a hall-of-helix entry to be published twice, and breakers are
per-revision so a broken candidate does not take the stable revision
down with it.
