Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- LRUCache get, set, and has operations store values, evict LRU entries upon reaching max capacity, and maintain recency order
- LRUCache sizeCalculation and maxSize track item weights, enforce size limits, and evict entries when total size exceeds maxSize
- LRUCache ttl configuration with updateAgeOnGet and purgeStale manages time-based entry expiration and stale item cleanup
- LRUCache dispose and disposeAfter callbacks execute with proper dispose reasons on eviction, deletion, and overwrites
- LRUCache fetchMethod and memoMethod resolve missing entries, support asynchronous fetching, and coalesce concurrent lookups
- LRUCache dump and load serialize and restore cache entries with metadata across instances
