Use the checked date and source confidence. If no official source date exists, the update stays in a verify-only state.
A practical reading guide for code claims: what can be trusted, what must be rechecked, and what should stay unknown.
For live code rows and confidence states, use the codes status page. For source-level context, open source status.
The same checklist can be reused weekly. If a code becomes unavailable, move it to historical notes instead of replacing it with inferred claims. This keeps page quality higher and avoids outdated SEO claims.
