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
- uuid.New returns a non-nil Version 4 UUID with RFC4122 variant
- uuid.NewString returns a valid 36-character hyphenated UUID string
- uuid.Parse correctly parses canonical hyphenated, 32-digit hex, and URN-prefixed UUID strings
- uuid.MustParse returns parsed UUID on valid string and panics on invalid input
- uuid.Validate accepts valid UUID string formats and returns error on invalid formats
- uuid.NewSHA1 generates deterministic RFC4122 Version 5 name-based UUIDs
- uuid.NewMD5 generates deterministic RFC4122 Version 3 name-based UUIDs
- uuid.FromBytes creates a UUID from a 16-byte slice and rejects slices not equal to 16 bytes
- uuid.UUID.URN formats UUID with standard urn:uuid: prefix
- uuid.UUID.MarshalText and uuid.UUID.UnmarshalText round-trip UUID text representation
- uuid.UUID.MarshalBinary and uuid.UUID.UnmarshalBinary round-trip 16-byte binary representation
