The daily reminder said one generic line to everyone, because the server
never sees a deck. Now the notification text is written in the browser
(lib/reminder.ts) and travels with the subscription:
- Personal: "3 cards are due in Sky deck", in the app's language, tapping
through to /review. Without notes (or with nothing due) it is the plain
nudge, translated in both languages — push.title / push.due.* / push.generic.
- POST /api/push accepts an optional message {title, body, url}; url must be
a path on this app, so a stolen subscription cannot make the notification
link elsewhere. The store keeps endpoint, keys, the message and createdAt
(a refresh no longer resets the timestamp).
- components/PushReminderSync.tsx refreshes the stored text when the app
opens and whenever the tab becomes visible (throttled to twice a day), so a
count is only ever sent while it is true.
- scripts/send-reminders.mjs sends each device its own text and falls back to
PUSH_REMINDER_TITLE/_BODY for a subscription that has none
(scripts/reminder-payload.mjs, unit-checked).
- /api/push/test previews the real reminder with a "Test:" prefix.
- deploy/freezmo-reminders.{service,timer}: the daily send as a systemd user
timer (18:00 local, Persistent, randomised), documented in the README.
- Settings copy, privacy page (en+cs) and .env.example say exactly what the
server now holds.
- phase2-test grew the whole path with a faked browser subscription: personal
text in en and cs, the generic fallback in both, the URL guard, and the
sender's preference order (81 checks).
Version 0.8.2, SW v104.
Answer history and schedules
- Every answer is recorded (deck, activity, topic, correct/wrong, time)
in a versioned IndexedDB log (freezmo-learning v1, stores answers +
srs), mirrored in memory for synchronous React reads and capped at
20k answers (oldest pruned). StudyFeed records as it grades.
- Light SM-2 schedule per activity: 1 day, 3 days, then interval x
ease; wrong answers return in ten minutes with the ease nudged down.
Review, mistakes, stats
- Library 'Smart review' card: due count, mistakes count (latest
answer wrong — clears itself when answered correctly), today's goal
progress. Review sessions freeze their item list at start.
- New /review (due across decks, ?mistakes=1 global or ?deck= per
deck) built on a shared SessionFeed with the study feed's snap/keyboard
mechanics, wake lock and a results slide.
- New /stats: day streak, five-week calendar, accuracy per subject and
per deck, weakest topics (>=3 answers), daily-goal progress.
- Daily goal configurable in Settings (10/20/30/50).
Exam mode
- New /exam: pick decks, question count, optional timer; no hints
(a NoHints context hides hint rows and the self-check escape);
results with score, per-deck and per-topic breakdown; wrong answers
land in the mistakes set through the normal history.
Reminders (conditional)
- VAPID-gated: GET/POST/DELETE /api/push and POST /api/push/test with
the standard route pattern, RATE_LIMIT_PUSH, zod, auth before body.
Subscriptions stored server-side as endpoint + keys only (PUSH_DIR).
UI hidden entirely without keys; iOS install note; service worker
push/notificationclick handlers; scripts/send-reminders.mjs for a
cron/systemd timer; web-push added as the one server dependency.
Verified: new phase-2 suite 42/42 (history/SRS shapes from a real study
run, mistakes clearing, review session, stats math, exam timer and
breakdowns, VAPID-less hidden state plus the configured
subscribe/validate/test/delete path against a second instance) plus
regression 74/74, mobile 52/52, wizard 80/80, declutter 116/116,
animation 8/8, native 35/35, phase1 38/38, i18n 25/25. Key parity
709/709. Lint + build clean. SW freezmo-v26.
