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.

Case
HOW- Goal
- verify pkg:golang/github.com/google/uuid@v1.6.0
- Packages
- Symbols
-
- uuid.NewRandom
- Environment
- go 1.26.5
- Created
- 2026-08-19T04:52:00Z
Contract
- uuid.NewRandom generates a valid RFC 4122 version 4 random UUID
- uuid.NewRandom generates distinct non-zero UUID values across consecutive calls
- uuid.NewRandom output formats correctly as a 36-character canonical string and parses back
- uuid.NewRandom 16-byte raw representation matches uuid.FromBytes
- Sample helper functions generate, validate, and parse random UUIDs
