/**

 * cells to their formatted error string (the known fast-path limitation the
 * safety scan exists for), strings are NFC-normalized, dates are detected
 * through the canonical number format, and blank rows are skipped with the
 * checkbox rule. Unsupported cell shapes fail closed, exactly like the Apps
 * Script source throws.
