Legacy content is an asset until it conflicts with current truth. If new pages are updated but old high-signal pages remain untouched, systems may still combine outdated fragments into current answers.
A practical cleanup sequence:
Each core page should show visible recency and version context so both readers and systems can trust the right version.
When legacy conflicts remain unresolved, publishing more pages can increase confusion. Readers and systems both struggle with competing versions.
Debt cleanup works best when ownership is clear: one canonical version, explicit legacy states, and a steady review cadence.
No. Update when possible, consolidate when needed, retire selectively.
Use exposure x decision impact x error risk.
Begin with a 20-page core cleanup sprint.
