- add the nullable TEXT column golem15_journal_categories.content (migration 202610090001)
- map it as models.Category.Content and emit category content on every categories row
- document the categories row shape and the stored-as-is HTML semantics
- Show unpublished or future posts as 404 without a data key unless owner or access_other_posts
- POST/PUT/DELETE posts and featured-images require a backend-audience JWT and PHP {error} strings
- Anonymous GET categories and tags return the PHP list keys; frontend-audience tokens cannot write
