Since the grants part creates a manifest's buckets after a delivery (ADR 0547), a module restarted by that
delivery can open a new state before it exists; OptionalBucket answered nil and the part never looked again
(mesh-delivery's checker and builder, state hearing, 2026-10-26). AwaitBucket binds on the server's
STREAM.CREATED advisory, or at the next use, and writes the latest value kept per key. The copied composer's
agreement test leaves that one row out: the controller's list is no longer loaded since the take-over.
process.Conn.Keeps, stdio.Keeps and the TypeScript keeps publish the announcement on
the module's own subject; afterwards a state the code did not announce is refused at
the call, so announcement and code cannot drift. The package goes to 0.1.15 for keeps.
