What's Changed

• Stop blaming a briefly offline KV stream on a missing grant by @pacepace in #559
• Scoped snapshot: the Chunk 06b cumulative-review fixes by @pacepace in #560
• Geo tile reads: a feature cache that reads once, a cached epoch read, and a bounded fake KV by @pacepace in #561
• Collections: bounded key-led reads and deletes, and no L2 by design by @pacepace in #562
• Chunk 04: versioned reads an edge may cache by @pacepace in #563
• Redshift: closing a dead connection no longer breaks the thread's other TLS connections by @pacepace in #568
• Design note: every collection carries a write generation by default by @pacepace in #569
• Collections: write generations, the expand stage by @pacepace in #570
• Collection generations stage 2: writers advance through the L3 broker by @pacepace in #584
• Large answers cross NATS gzipped, and a tool pod caches answers by version with nothing left behind by @pacepace in #586
• Collection generations stage 3: the access tables are switched on and followed row by row by @pacepace in #587
• Datasource export: one allow-listed UNLOAD, read back and checked before load by @pacepace in #588
• A caller's namespaces, asked once and followed through the access tables by @pacepace in #589
• A geography layer name fits an epoch subject: strict on write, lenient on read by @pacepace in #606

• Collection generations contract stage: generations are the only invalidation by @pacepace in #609

• Scoped snapshot: write and rebuild claims held as KVLease holds, no hand-rolled claim state by @pacepace in #687
• Final review fixes: grouped fingerprints tested, refused exports deleted, one keyset builder, one fingerprint statement, one hub-ask helper, attribution enforced by @pacepace in #692
• One lease: the cross-pod lock runs on KVLease and lives in core coordination by @pacepace in #721
• Background operations: every replica reports the newest finished run by @pacepace in #727
• Background operations: a run that did nothing is not the newest run, and a lost record is written again by @pacepace in #728
• One primitive for a pod's operation coordinated across replicas, and a limit on the datasource client's asks by @pacepace in #762
• Coalesced operations: every replica says how far the run is, once, and when its work is over by @pacepace in #766

• Final review of 0.66.0: the fixes by @pacepace in #769
