📝 WalkthroughWalkthroughThe PR adds the ChangesCitation metadata rule bundle
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds citation metadata extraction while preserving generic-page behavior, but the current package metadata links to a 404 and the documented test example does not run as written. The change is mergeable with explicit owner awareness and follow-up on these bounded usability issues. Sequence Diagram(s)sequenceDiagram

- Line 4: Update the homepage in this manifest and every affected package
manifest to use valid repository package paths instead of the broken GitHub
/packages/<name> convention. Perform the correction as one repository-wide
sweep, preserving each package’s existing name-specific destination.
In `@packages/metascraper-citation/README.md`:
- Line 14: Update the npm install command in the README by removing the leading
shell prompt character, leaving the command itself unchanged so it satisfies
markdownlint MD014.

fixture/parser to exclude `.content-meta-rights` access links from the generic
author match, while still selecting valid author elements such as `Sarah Maria
Vargas`. Update the expected snapshot and add a regression assertion covering
