Article citations fail or change content: how do you update evidence without changing the original meaning?

Map the broken citation to a specific claim

This applies to moved documentation, irrelevant redirects and deleted announcements returning 404. Preserve the original URL, title and supported sentence instead of reconstructing from memory. A 200 page may be an error template or changed content. Successful redirection does not establish support for the original numbers or claims.

Inspect final destinations and changed content identity

Inspect final URL, title, key passages, dates and applicable versions. Separate permanent moves, temporary faults and substantive changes. Reposts and summaries can omit conditions; similar search snippets do not establish equivalence. Historical claims need period-appropriate records rather than current rules imposed retroactively.

Find equivalent primary evidence or mark the gap

Prefer official moved pages, versioned documentation and traceable records and verify support before replacing links. If new evidence invalidates a conclusion, revise it substantively and document the change. Keep unresolved gaps explicit rather than fabricate citations or copy long protected passages. Any necessary excerpt should be short and attributed.

Recheck both accessibility and claim support

Open each replacement and verify support, then inspect versions, numbers and limitations for accidental changes. Content spot checks remain needed after automated status tests. Acceptance means readers can trace supporting evidence. Normal HTTP statuses and larger citation counts do not establish trustworthy reasoning.

This article replaced no site sources or claimed a particular existing link is broken. Historical evidence can be unrecoverable and needs disclosed limits rather than fabricated archives. Status checks detect access issues but not full semantics. Core conclusions need verified facts rather than convenient rewriting to clear a broken-link warning.
