Sources age at different speeds. Product documentation may change monthly, while a stable definition or historical dataset can remain useful for years.
Classify evidence by volatility
Tag each important source as fast-changing, periodic, event-driven, or stable. Record the publisher, claim supported, last checked date, and likely review trigger. Use shorter intervals for prices, interfaces, regulations, and platform policies.
Review the claim, not only the link
A URL returning 200 does not prove the evidence still supports the sentence. Re-read the relevant section, check its date and scope, and compare the article's wording. Replace a source only when the substitute genuinely supports the same claim.
Route judgment cleanly
An operator can flag dead links and changed documents. A subject owner decides whether new evidence changes the conclusion. Preserve an audit note when a claim is narrowed or removed.
This calendar makes daily article production safer: new work does not quietly inherit stale facts from an old internal reference list.
