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.ScanArgError encapsulates column index, field name, and underlying error for row scanning failures
  2. pgx.ScanArgError.Error formats descriptive error string containing field name, column index, and underlying error
  3. pgx.ScanArgError.Unwrap returns underlying error and supports standard errors.Is and errors.As unwrapping
  4. sample helper functions construct, detect, extract details from, and format pgx.ScanArgError
  5. sample.ValidateScannedField validates scanned column values and wraps failures into pgx.ScanArgError
