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
- xxhash.Sum64 returns consistent 64-bit hash for byte slice
- xxhash.Sum64String produces identical hash to Sum64 on matching string
- xxhash.Sum64 and Sum64String handle empty input identically
- xxhash.New streaming Digest matches one-shot Sum64 calculation
- xxhash.Digest Reset clears state for subsequent hashing
