ensureDbCompatibility ran ALTER TABLE / CREATE TABLE IF NOT EXISTS on the
login, register, token and session paths, mirroring columns every
migration under prisma/migrations already creates. The entrypoint applies
those migrations before the server listens and stops the boot when one
fails, so the mirror never had work to do, and DDL on a request path
needs the table's owner: a connection that may only read and write rows
fails every login on it. Drop the module, its call sites and the mocks
that stubbed it out.
The foreign-document ownership test only needs owner A's upload to exist;
it seeded the user into a discarded local. Call it for its effect instead
so lint stays clean.
P3-1. Integration coverage the unit mocks cannot pin: migration 0229's join +
cascade, create-with-documents in one transaction, foreign-doc refusal at
create, the public serve route (passphrase gate, token confinement to the
frozen set, exact-bytes Class A posture, foreign id + revoked link → 404), and
membership cascade on document delete.
