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
- generate and validate time-ordered UUID v7 with github.com/google/uuid
- Packages
- Symbols
-
- uuid.NewV7
- Created
- 2026-08-18T20:23:42Z
Contract
- uuid.NewV7 returns non-nil UUID v7 without error
- uuid.NewV7 returns UUID with Version 7 and RFC4122 variant
- uuid.NewV7 generates time-ordered UUIDs where successive UUIDs have equal or increasing byte order
- uuid.Parse successfully parses generated UUID v7 string back to original UUID
- uuid.Validate confirms generated UUID v7 string is valid
