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 16-byte UUID of Version 4 with RFC4122 variant
- uuid.NewString generates a valid 36-character hyphenated UUID string
- uuid.Parse correctly parses canonical hyphenated UUID strings and rejects invalid format
- uuid.ParseBytes and uuid.FromBytes convert byte slices to UUID correctly
- uuid.Validate validates UUID string format without allocating
- uuid.MustParse returns parsed UUID on valid string and panics on invalid input
- uuid.NewSHA1 and uuid.NewMD5 generate deterministic name-based Version 5 and Version 3 UUIDs
- uuid.UUID supports binary and text marshaling round-trip and URN formatting
