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. MIT-0

Contract

  1. pgx.NamedArgs.RewriteQuery rewrites named parameters into positional placeholders ($1, $2) and returns ordered argument slice
  2. pgx.NamedArgs reuses positional placeholders for repeated parameter names
  3. pgx.NamedArgs preserves @ characters inside SQL string literals and comments
  4. pgx.NamedArgs maps missing parameter keys to nil without returning an error
  5. sample helpers provide structured query building, map merging, and parameter checks using pgx.NamedArgs
