Migration checklist

1. Find every request that still uses these model ids before December 15, 2026.
2. Point each request at the replacement in the table. If a cell says "Not published", the provider did not name one.
3. Open the source link on each row and read that page before you switch.
4. Run the scan page on your code to catch the ids in this table.

Scan your code for these model ids. Each migrate link opens the diff for that model.
