Sample

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 deterministic UUIDv5 using namespace and name with uuid.NewSHA1
- Packages
- Symbols
-
- github.com/google/uuid.NewSHA1
- Created
- 2026-08-19T09:26:51Z
Contract
- uuid.NewSHA1 generates a valid version 5 UUID with RFC4122 variant
- uuid.NewSHA1 produces deterministic UUID output for identical namespace and name
- uuid.NewSHA1 produces distinct UUIDs for different names in the same namespace
- uuid.NewSHA1 produces distinct UUIDs for the same name in different namespaces
