Opening a tip before answering is a nudge. The answer that follows is
still right — it is counted as right, and the percentage is not docked —
but it is not the same as right, so it keeps its own arc on the donut and
its own line in the legend: "3 correct after a tip".
attempt_answers.used_hint records it. The player reports which questions
had a tip opened before the answer went in; a tip read afterwards is
revision and does not count, which is the difference two of the tests
turn on. Both endings agree about it — an explicit submit carries the
list, and an exam that runs out takes it from the saved progress, so a
tab closing cannot launder a score.
Found while wiring this: RichText declared its component overrides inline
in the render, so every one was a fresh component type and React
remounted the whole rendered tree on each render. An open tip closed
itself every time the exam clock ticked. The map is memoised now.

It ran on a wall clock. An hour away from the tab spent an hour of the
exam on questions that were never shown, and every per-question figure
was a fiction — which is the number the whole analysis is built on.
Three things stop it now. The tab being hidden, which catches switching
away. An explicit pause. And, for the commonest case the other two miss
— the tab left open on the exam while the person is in another room —
an idle watch: three minutes with no mousemove, key, wheel, touch or
scroll and it asks "Still there?", with the clock already stopped by the
time the question appears. A stray pointer movement does not answer it;
somebody has to say they are there.
Three minutes, not one, and scrolling counts as activity: reading a long
vignette is minutes without a click, and interrupting genuine reading to
ask whether you are reading is worse than occasionally crediting a
minute nobody was there for.
The server was the other half. seconds_remaining computed from
started_at and total_time, so a paused client made no difference to what
the server thought was left. It reads the saved time_left now, which is
what the player decrements only while the exam is on screen, falling
back to the wall clock for progress saved before this existed.
And a five-minute warning, said once. An exam that ends without notice
is a scramble; one that nags is a distraction.
Reverts the exam-exit-submits rule from earlier in this branch, which
was built on the opposite premise and would have charged wall-clock time
and then graded an exam whose clock should simply have stopped. Leaving
suspends, in both modes, and the overview no longer promises a clock
that does not stop for a break.

An unsuspended exam keeps running. When its clock runs out it is
submitted with what was answered and the score counts — a learner who
ran out of time sat an exam, which is a result and not an accident to
hide. Previously it was graded, flagged expired=1, excluded from every
statistic, and the client was told the opposite ("submit manually").
- attempt_expiry.settle_if_expired: one path, used by resume and by the
sessions list, so an exam left open elsewhere shows its score rather
than "in progress" forever. Suspended attempts hold their clock and
never expire.
- resume returns {expired_submitted, attempt_id}; the client opens the
analysis. The suspend dialog and the leave warning now say what
actually happens.
- delete: saved progress and device lock cleared; a study-plan block
whose only completed attempt is deleted goes back to unfinished.
- POST /attempts/reset-all: typed RESET, removes attempts, answers,
in-progress state, plan progress, reading marks, saved questions and
question notes; leaves the account, authored content and AI chats.
Settings → Your data, with the counts reported afterwards.
Also fixed on the way: the first version of the sessions-list change
mutated the dict it was iterating; the test only passed because it had
one attempt. Now two.
Backend 223/223, frontend 258/258.
