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. MIT-0

Contract

  1. NewCache returns an error when NumCounters, MaxCost, or BufferItems is zero
  2. Set adds key-value items with cost and Get retrieves existing values
  3. Del removes an existing key so subsequent Get returns false
  4. SetWithTTL returns false and rejects items when given a negative TTL duration
  5. Clear empties all stored items and resets policy counters and metrics
