Review r0 M3. The indirect sweep disposed stale resolutions without holding their gates, and any reader/writer that fetched a handle before waiting on its gate could then use an instance a sibling had evicted and disposed - a spurious comms fault and Degraded. The sweep now evicts under each key's gate, and read/write re-resolve the handle once the gate is held (reconnecting single-flight if it was evicted; a retired state never reconnects).
