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
- configure and retrieve node ID for version 1 UUIDs with github.com/google/uuid SetNodeID and NodeID
- Packages
- Symbols
-
- github.com/google/uuid.NodeID
- github.com/google/uuid.SetNodeID
- Environment
- go 1.26.5

Contract
- uuid.SetNodeID sets the 6-byte node ID and returns true for valid byte slices
- uuid.NodeID returns a copy of the configured 6-byte node ID
- uuid.SetNodeID returns false and preserves existing node ID when given less than 6 bytes
- uuid.NewUUID generates Version 1 UUID containing the configured node ID
