 Message feedback is not a Session event or projection. It remains in the storage-domain sidecar and causes no telemetry handoff. The Host Remote contract ships with the service; the client Remote aggregate mount and UI consumer are separately owned and deferred.

 - **Client aggregate and UI are absent** — the Host Remote contract ships, but the Client Remote aggregate contribution and any UI consumer are separately owned and deferred.
 - **Compare-and-set is single-process** — the per-Session queue serializes one service instance only; multiple Host processes writing one storage root can still lose updates because storage-domain exposes no cross-process conditional write.
-- **No durable Session deletion cascade** — Session persistence has no deletion surface, and `session/disposed`/`host/session-removed` mean detach rather than durable deletion. The service therefore retains empty rows and may leave orphan rows after out-of-band log removal instead of deleting valid feedback on detach.

The service therefore retains empty rows and may leave orphan rows after out-of-band log removal instead of deleting valid feedback on detach.
 - **Detach/catalog retirement window** — a request in the narrow interval after live detach but before the persistence catalog materializes the header can receive `session-not-found`; callers retry after retirement materialization.
 - **Header identity is not a content fingerprint** — `{createdAt, cwd}` detects reuse only when those fields differ; a cloned log retaining the same header identity is indistinguishable.
 - **Trusted caller boundary** — `list`/`put`/`delete` carry no authenticated actor or audit identity. A deployment must expose the Host gateway only through its trusted or separately authenticated boundary until authorization and attribution are added.
