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.
A browser session on its own could start TOTP enrollment or register a
security key. Combined with a pending secret counting as a factor, that let
a stolen session give itself a second factor, register a passkey with it,
and keep access after the owner changed the password.
TOTP setup and security-key registration now pass on the cookie path only
when the session signed in or completed a second factor in the last five
minutes, or when the body carries a proof in the step-up shape (password,
a confirmed authenticator code, or a passkey or security-key assertion).
The settings cards ask for that proof when the server answers
auth.reproof.required and retry the same call with it. The Bearer path is
unchanged: its elevation already is the proof.
Every route that checks a password or a factor as a re-proof now uses one
verifier and one per-account budget of five attempts per fifteen minutes,
shared with the step-up mint, and records each refused proof as
auth.mfa.failed. Passkey enrollment and password change had neither the
limit (passkey enrollment) nor the audit row (both). A structural test
freezes the set of credential-verifying routes and requires a throttle and
an audit call in each.
