packages/cultcache-rs forked from GameCult/cultcache-rs at the 5c69bfc
monorepo import and the two lineages then diverged in both directions. The
standalone repo took 28 commits of engine work CultLib never saw: typed SoA
projection, atomic heterogeneous batch publication, single-entry and
conditional batch CAS, a transactional keyed redb backend with serialized
cross-process opens, lockless provider snapshot reads, RAII read-only shared
snapshots, snapshot-fenced replace/append, crash-atomic single-file snapshots,
compaction fences, portable and canonical byte fields, and unified retained
storage authority. That body is 3,714 lines with 48 tests against CultLib's
1,554 with 18.
CultLib is the canonical home because wire parity conformance lives here and
nothing outside it is tested for cross-runtime agreement. A runtime-specific
core-stack repo cannot hold the engine every other runtime must agree with.
The standalone body lands as the base rather than merging 28 commits backward.
It is already proven against a CultLib-derived cultnet-rs: Ghostlight vendors
exactly this pairing and compiles. Here, cultcache-rs passes 46 tests and the
cultnet-rs RUDP gate passes 20 with no source change.
Retained debt, not carried forward: a0b31b8 recovered schema-stamped records
missing catalog entries (SchemaStamped, infer_schema_name,
infer_schema_version_from_payload) and 743eaa5 hardened snapshot replacement
(SnapshotReplacementStage, CommittedSnapshotDurabilityUncertain, stale
candidate cleanup, with_exclusive_lock_using_unlock). Their tests were
white-box against internals this body does not have. The standalone
independently made single-file snapshots crash atomic and cleaned abandoned
staging files, so the durability guarantee is probably held under other names
-- probably is not proven. Re-establish both as black-box tests against the
new API before the standalone repo is retired.
