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.

HOW- Goal
- verify pkg:golang/github.com/google/uuid@v1.6.0
- Packages
- Created
- 2026-08-18T22:01:05Z
Contract
- assert uuid.New, uuid.NewRandom, uuid.NewString, and uuid.NewRandomFromReader generate RFC 4122 version 4 UUIDs with version and variant bit patterns
- assert uuid.NewRandomFromReader propagates reader error and handles short byte reads returning uuid.Nil
- assert uuid.Validate and uuid.Parse accept standard hyphenated, braced, unhyphenated hex, and URN formats and reject malformed representations
- assert uuid.NewMD5 and uuid.NewSHA1 generate deterministic RFC 4122 version 3 and version 5 UUIDs across standard namespaces
- assert uuid.NewUUID and uuid.NewV6 generate time-based version 1 and time-ordered version 6 UUIDs with valid timestamps and node IDs
- assert uuid.UUID and uuid.NullUUID support binary, text, and JSON serialization as well as sql driver.Valuer and sql.Scanner interfaces
