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
- assert uuid.NewUUID generates RFC 4122 version 1 UUID with valid timestamp, clock sequence, and MAC node identifier
- assert uuid.NewSHA1 and uuid.NewMD5 generate deterministic RFC 4122 version 5 and version 3 name-based UUIDs across standard namespaces
- assert uuid.FromBytes converts 16-byte slice to UUID and rejects byte slices of length not equal to 16
- assert uuid.Parse and uuid.ParseBytes support standard hyphenated, unhyphenated hex, and URN prefixed UUID formats
- assert uuid.UUID implements binary, text, JSON serialization, and database/sql driver Valuer and Scanner interfaces
- assert uuid.NullUUID correctly handles null and non-null states for database/sql and JSON serialization
