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 generates a non-nil RFC 4122 version 4 random UUID
- uuid.New generates distinct unique UUIDs across successive calls
- uuid.Parse successfully parses standard 36-character hyphenated UUID strings
- uuid.Parse parses 32-character hexadecimal UUID strings without hyphens
- uuid.Parse parses curly-braced UUID strings
- uuid.Parse parses standard URN format UUID strings starting with urn:uuid:
- uuid.ParseBytes parses byte slices with equivalent result to uuid.Parse
- uuid.Parse rejects invalid format and malformed UUID strings with error
- uuid.New and uuid.Parse round-trip accurately preserves UUID value and bytes
