- content: POST nodes/{id}/quiz/complete and lessons/{id}/complete refuse a locked island
(403 node_locked, same rule as /api/home) and a user who has not answered every question
(409 answers_missing). Before, only a user with zero hearts and no answers was refused, so
anyone else finished any island, locked or not, and finishing a locked island's lessons
unlocked it. A node or lesson with no questions still passes when unlocked, with no XP.
The client can no longer understate totalQuestions to buy stars.
- throttle_scope on 15 routes that had none (question bank without login, intro, hearts,
notifications, tickets, plans, subscription status, orders, offers, affiliate, assistant
history and feedback, logout).
- admin: OTPCode and Session can only be added/changed by a superuser.
- deploy.sh: integrity-checked DB backup before migrate (keeps the last 2); no migrate without it.
- docs and CLAUDE.md updated to say what is verified and what is not.

accounts.0008 drops the columns and refuses to run while guest rows exist.
Docs describe the current state; tests that only proved guest behaviour are gone.

- The zero-hearts check moved inside the answer transaction: two wrong
answers sent at once with one heart left were both accepted (reproduced
with two threads).
- Finishing a lesson or an island without hearts and without having
answered its questions is now 403 no_hearts; before, quiz/complete let
a student move on island after island with zero hearts. Losing the last
heart on the last question still finishes the island.
- A heart that came back while waiting is now saved before answering, so
the reply no longer says 0 hearts left (the app then showed the
no-hearts page to someone who had a heart).
- The 403 also carries fullRefillAt for the waiting screen.
