Superseded Standard checker — check citations for superseded standards
Finds superseded standard editions and repealed laws cited in your .rst/.md docs — ISO 27001:2013, PCI DSS 3.2.1, FIPS 140-2, Privacy Shield, the old SCCs — with the date each one died. Runs entirely in your browser — nothing is uploaded.
Free here: Check the document open in the editor and name every dead citation in it. In the editor: Sweep every .rst/.md in the workspace and write a dated STALE-CITATIONS.md you can hand an auditor — that part asks for a licence key.
Same engine as the VS Code extension, byte for byte.
