citation agent linked wrong source url after 301 redirect

TL;DR

Wrong citation URLs after redirects happen when the agent cites the pre-redirect URL while the content moved. Resolve every citation URL at citation time, store the final URL after redirects, and re-verify links before publishing so readers land on the actual source.

The error

citation check failed: briefing links https://old-ir.example.com/q3 (301 to https://new-ir.example.com/results/q3)
linked URL returns 301; content lives at the target.

Fix it

1. Resolve each citation URL with a HEAD request that follows redirects, and record the final URL and the redirect chain. Expected: Expected: the log shows the 301 hop and the final 200 URL for every citation.

2. Rewrite the briefing's citations to the final URLs, keeping the original as a comment for traceability. Expected: Expected: every published link returns 200 directly with no redirect.

3. Add a pre-publish link check: fetch every citation URL and fail validation on anything that is not a final 200. Expected: Expected: redirect chains get caught before the briefing ships.

4. Re-check citations on a schedule for evergreen briefings; IR sites restructure and old final URLs can start redirecting again. Expected: Expected: link rot is caught by monitoring, not by readers.

When to use

• Your briefing's citations land on redirect pages instead of the source.
• You need citations that resolve directly for readers and auditors.
• You publish briefings that get referenced for months.

When not to use

• The redirect target has the same content - then update the link, the citation is still valid.
• The source genuinely moved and the old content is gone - find a replacement source.
• You cite via archive links (Wayback) - then redirects do not apply.

Why it happens

IR and news sites restructure URLs constantly, leaving 301s behind. Agents capture the URL they first saw (often from search results or old pages) and never re-resolve it. The citation then points at a redirect that may eventually break, and strict citation checkers flag it immediately.

Same failure and fix; some searchers phrase the query this way.

Edge cases

• Some 301s are conditional on user agent or geography; resolve with the same client profile readers use.
• Redirect chains longer than 3 hops often indicate the content moved twice; verify the final page is actually the cited content.
