Support pages should be reviewed when an official source changes, when product scope changes, and before a new calculation rule is shipped.

Pages include a last-reviewed date so readers can see whether the content has been recently checked.

A retirement rule should not move from content into the calculator until it has a named source, typed input and output, and unit tests.

The UI should not contain hidden eligibility logic. If the product needs new behavior, it belongs in the deterministic rules engine.

If a page is unclear or a source changes, the page should be corrected before related calculator output is expanded.

Corrections should preserve the independent-site disclaimer and should not imply affiliation with OPM.
