Intentionally Excluded
Navigation, footers, scripts, styles, and buttonsThe comparator strips page chrome so it checks document text, not the surrounding website shell.
Pages without Markdown mirrorsStandalone tools, dashboards, data assets, and indexes are outside this receipt unless they gain mirrors later.
Semantic equivalenceThe check catches textual divergence. It does not prove two texts mean the same thing in every context.
Limitations
Token overlap is robust enough for dropped text, but it is not a plagiarism detector or a semantic model.
Checksums are included for drift triage only; exact equality is not required because HTML and Markdown extractors intentionally differ.
Future pages need mirrors and gate coverage before they are covered by this receipt.
