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.Value returns standard string driver.Value for non-nil UUID
- UUID.Value returns standard 36-char string driver.Value for uuid.Nil
- UUID.Scan parses standard 36-byte hyphenated UUID string and byte slice
- UUID.Scan parses 16-byte raw binary representation
- UUID.Scan accepts nil without error
- UUID.Scan returns error on invalid string format or incompatible type
