Trigger
During the Astro portfolio migration, a project card looked fine but opened only a one-line summary. The detailed HotDealppom content still existed, but users could not reach the video, screenshots, and technical record from the card.
User Correction
The first AI fix checked whether a modal target was a list item. That solved one symptom but not the real rule. The better requirement was that every non-intentionally-hidden content item must have a public reachable path.
Fix
- Replaced the portfolio-only heuristic with `validate:content`.
- Validated built post routes, tag/index reachability, and localized portfolio detail reachability.
- Kept intentionally hidden records in an explicit declaration list.
- Added the work back to the portfolio as an AI collaboration quality-gate example.
