Singleton row that holds the lowest still-available tx_seq
and checkpoint_seq. It is the durable authority for the
bitmap CFs’ compaction filters and feeds available_range
requests.
Each open RPC-store schema owns an Arc<AtomicU64> whose clones
are captured by that database’s bitmap compaction filters. Schema
construction loads the persisted tx_seq floor into the atomic.
Pruning and restore paths commit the singleton row before
publishing its value to the matching database-local atomic.
