CultCache.Update reads its version and its apply input from one durable read of the record's home store (new internal CacheBackingStore.ReadDurable), never from the held instance, so an in-place mutation of a held object can no longer be persisted by Update. A store-less cache keeps the held copy. The per-loss pull is replaced by one pull before LostRace.

Spec variants:cut_spec:cut-update-from-stored-bytes.r1, report variants:cut_report:cut-update-from-stored-bytes.h1, follow-up variants:follow_up:update-copy-from-stored-bytes. Consumer-side test in GameCult.Caching.OutsideStoreTests.

CultCache.Update reads its version and its apply input from one durable read of the record's home store (new internal CacheBackingStore.ReadDurable), never from the held instance, so an in-place mutation of a held object can no longer be persisted by Update. A store-less cache keeps the held copy. The per-loss pull is replaced by one pull before LostRace. Spec `variants:cut_spec:cut-update-from-stored-bytes.r1`, report `variants:cut_report:cut-update-from-stored-bytes.h1`, follow-up `variants:follow_up:update-copy-from-stored-bytes`. Consumer-side test in GameCult.Caching.OutsideStoreTests. 🤖 Generated with [Claude Code](https://claude.com/claude-code) 
Add CacheBackingStore.ReadDurable (single-file and directory stores), factor the
directory pull's lease/retry load into LoadManifestPages, and make a store-backed
Update take apply's argument and the Expected version from that read, with the load's
deterministic element ids. The per-loss pull moves to the LostRace branch; a
store-less cache keeps the held copy and its codec refusal.

Caching tests: pin the variant refusal message and ReadDurable leaving the store view alone; start TwoWriters rounds together

The directory race test no longer collided once each attempt reads fresh, so each round
now starts both writers at a barrier.
