Two tasks. The first is the whole swap in one commit — dependencies, generated types, db.ts, the reconverted file, the ported drift test and the new 409 assertion — because splitting it would put a commit on the branch where the build is broken or both builders are present, and neither is a state worth being able to bisect to. The second is the conventions document, which touches no code and is much shorter than the one it replaces.
The plan carries the converted adminCategories.ts in full rather than describing it, and names the two places the conversion could silently change behaviour: the four selects must keep answering id, name, parent_id, sort_order and item_count, and the unique-violation catch must keep producing a 409. The existing category integration suite is the gate on the first, and a new test is the gate on the second.
Three expected outputs are written down so a wrong one is caught at the step rather than three steps later. Codegen must report 18 tables, not 19 — 19 means pgmigrations leaked past the exclude flag. The generated Categories interface must spell parent_id and sort_order, because camelCase there means --camel-case got turned on and the mapping layer this swap removes has come straight back. And the integration count should rise by exactly one.
