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.

Contract
- uuid.NameSpaceDNS has standard RFC 4122 DNS namespace UUID string value
- uuid.NameSpaceURL, uuid.NameSpaceOID, and uuid.NameSpaceX500 have standard RFC 4122 namespace UUID string values
- uuid.NewSHA1 with NameSpaceDNS generates deterministic Version 5 UUID with RFC4122 variant
- uuid.NewMD5 with NameSpaceDNS generates deterministic Version 3 UUID with RFC4122 variant
- uuid.NewSHA1 generates different UUIDs for different predefined namespaces with identical data
