## Scope

StateRecoveryBench is an official Zaxy benchmark lane for partial-cue accepted-state recovery under stale, distracting, incomplete, and no-safe-answer event histories.
`memory_fabric_checkout` is the production guardrail baseline. Associative projection rows remain diagnostic research baselines and are not product claims.
This benchmark does not replace LongMemEval or CoordinationBench.
