Review findings applied across the group: - storage hub: stale disposers no longer remove a successor registration; the package now default-exports the Storage service class per the service-package export shape. - json backend: failed publishes roll back the authoritative memory state (a rejected write can no longer resurface via get() or ride the next publish); close() drains in-flight writes and blocks in-flight opens; double-open rejects as a plain caller error instead of malformed-medium. - sqlite backend: loadAll builds records on a null prototype (__proto__ keys round-trip instead of polluting), user_version is stamped only after the schema is fully created, and corrupt record JSON rejects as malformed-medium instead of a bare SyntaxError. - domain form: writes persist before mutating authoritative memory or emitting; DomainChanged is a put/deleted discriminated union. - workspace: attach/detach idempotence decided on the write chain (stale snapshots no longer short-circuit), create() requires a directory, and startup fails loud on duplicate stored paths. Eleven regression tests pin the fixed behaviors.
