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.Timestamptz.Scan parses formatted timestamp strings with timezone into time.Time with Valid true
- pgtype.Timestamp.Scan parses formatted timestamp strings without timezone into time.Time with Valid true
- pgtype.Timestamptz.Scan accepts time.Time values preserving exact timestamp
- pgtype.Timestamptz.Scan handles special values infinity and -infinity with InfinityModifier
- pgtype.Timestamptz.Scan handles nil input by setting Valid to false for SQL NULL
- pgtype.Timestamptz.Value returns time.Time for valid finite timestamps, string for infinite, and nil when invalid
- pgtype.Timestamptz ScanTimestamptz copies and TimestamptzValue extracts underlying value
- pgtype.Timestamptz.Scan returns an error for malformed or unparseable timestamp strings
- Sample helper functions construct and parse finite, infinite, and null timestamptz instances
