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 v4 UUID value
- uuid.NewString generates a valid RFC 4122 v4 UUID string
- uuid.NewRandom generates a version 4 UUID with RFC4122 variant
- uuid.NewV7 generates a version 7 time-ordered UUID with RFC4122 variant
- uuid.Parse parses valid UUID strings and returns error for invalid strings
- uuid.Validate returns nil for valid UUID strings and error for invalid strings
- uuid.MustParse returns UUID on valid input and panics on invalid input
- uuid.FromBytes creates UUID from 16-byte slice and rejects other lengths
- uuid.NullUUID implements driver.Valuer and sql.Scanner and JSON marshaling
