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
- assert pgx.StrictNamedArgs rewrites named parameters into $1, $2 positional placeholders and extracts matching arguments in order
- assert pgx.StrictNamedArgs reuses identical positional parameter placeholders when the same named argument appears multiple times
- assert pgx.StrictNamedArgs rejects queries referencing missing named parameters with an error unlike pgx.NamedArgs which produces nil
- assert pgtype.Numeric parses fixed-point decimals, preserving negative exponent scale and unscaled big integer values
- assert pgtype.Numeric represents NaN and Infinity modifiers formatted as standard SQL driver values
- assert pgtype.Date distinguishes calendar dates, SQL NULL, and PostgreSQL infinity modifiers without timezone shifts
- assert pgtype.FlatArray decodes 1-dimensional PostgreSQL text arrays into strongly typed Go string slices
