Blogs.BlogId was a one-time copy of BlogNames and nothing kept it
current: 12,238 blogs first seen after 2026-08-07 had a BlogNames ID
but a NULL Blogs.BlogId, so GetBlogs' join on BlogId silently skipped
them and their 23,148 notes.
- retire-blognames.sql: stub Blogs rows for the 17 unregistered note
participants, backfill IDs (none renumbered), make ix_Blogs_BlogId
UNIQUE, drop BlogNames, and add triggers that stop a Blogs row with
a BlogId from being deleted, renamed or renumbered
- AddNote registers both blogs via RegisterBlog (Blogs row + MAX+1 ID)
and every query resolves names through Blogs instead of BlogNames
- verify-db-schema.sql reports a DB that still has BlogNames (1e)
- Update TL.db.md, AGENTS.md and the DB Browser saved queries
