+notes = "Headless only (redact_mark regex, optional validate luhn, mod97 or iban; issue #1886): no UI entry yet. Rust regex syntax, matched in linear time with no look-around or back-references; expression capped at 1024 bytes, compiled size and nesting capped, empty-matching expressions refused. Matches run on the page text as the pattern matchers see it (words and lines joined by one space), so a match cannot span a page break. Missing: a UI field, a mask for checksums that need more than the whole match (for example the French social security key), and a check against Acrobat's own custom-pattern syntax (not observed)."
