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
- pgtype.Date represents calendar date values with time.Time, InfinityModifier, and Valid fields
- pgtype.Date implements driver.Valuer returning time.Time for finite dates, string literals for infinity, and nil for SQL NULL
- pgtype.Date implements sql.Scanner parsing time.Time, date strings, infinity literals, and nil values
- pgtype.Date implements ScanDate and DateValue for pgx native date handling
- pgtype.Date encodes and decodes in text and binary wire formats using pgtype.Map
- sample helpers provide date construction, string parsing, formatting, and wire format serialization
