Compare two audits of a site and get the change set: entities added and removed, entities that gained or lost an @id, occurrence changes, new and resolved conflicts and dangling references, summary deltas, and the pages each audit saw that the other did not. Defaults to the previous audit versus the latest. An entity is only reported as removed when every page that declared it was crawled again; anything unproven is reported separately as not crawled, so a smaller crawl never reads as a site that deleted its structured data. Each gainedId and lostId entry carries a coverage field saying whether the newer audit visited every page that declared the old version and found the replacement there. Absence of a gainedId entry is not proof a fix failed: the match needs the type and the name to be unchanged, so changing the @id and the name in one edit appears as a removal plus an addition instead. Fix-and-verify loop: call list_entities with problem="no-id" to find entities declared on several pages with nothing to tie them together, give each one an absolute @id, re-run the audit with run_audit, then call compare_entities and check that gainedId contains the keys you fixed. gainedId is the only confirmation that the fix landed: an entity that gained an @id changes key, so it would otherwise look like one removal plus one addition. Check each entry's coverage field before calling it done: "proven" means the newer audit visited every page that declared the broken version AND found the replacement on all of them, "partial" means one of those could not be established.
