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.

/**
|
|
* Sends the daily review reminder to every stored push subscription.
|
|
*
|
|
* Meant for cron or a systemd timer, e.g.:
|
|
* 0 18 * * * cd /path/to/freezmo && node scripts/send-reminders.mjs
|
|
*
|
|
* Silently does nothing when VAPID keys are not configured (the whole
|
|
* reminder feature stays hidden in the UI in that case).
