571 categories, 21 uploaded documents, 14 articles, 8 card decks, 30
shared tests and 2 questions carried somebody's name — mostly
daniel@danvics.com, which is not even the working administrator any
more. So "who may edit this" partly depended on who happened to create
it, and handing the site to somebody else would have meant rewriting
every one of those rows.
Migration q6a7b8c9d0e1 empties those owner columns and makes them
nullable, because ownerless is now a legitimate state and a NOT NULL
owner is exactly what forced a name onto every row. Nothing is deleted
and nothing moves. What keeps its owner, deliberately: attempts, notes,
favourites, collections, folders, study-plan progress, and the quizzes
that are somebody's own sittings rather than shared bank tests.
study_plans needed nothing — it never had an owner column.
Then the code, so it cannot grow back. Authorship is no longer a way in
anywhere: may_edit_question and can_edit_article ask the role and the
grants and nothing else; the article draft, status and delete paths lost
their "or you wrote it" arm; decks are the bank's, so an educator
reaches any of them and a learner reaches the shared ones; documents are
the corpus, so they are editors-only rather than "mine"; and every
creation path writes user_id NULL. The bank listing's "mine" facet went
with it — it counted nothing and could only ever count nothing.
Verified against production as a real learner account: every bank write
403s, admin settings 403, documents empty. As an admin, everything
opens.
Also: a category grant no longer offers Editorial in the menu. It offers
Questions and Images, which is what a grant covers; Editorial is the
whole library's review queue and its route is moderator-only, so the
entry was a door that answered "Not yours to open".
Six tests changed rather than deleted — they asserted the old model, and
each now asserts the new one: writing an article does not make it yours,
writing a question does not make it yours, an answer image is not opened
by authorship, the tutor is not opened by authorship.
