Аудит выключателя геймификации выявил элементы, НЕ покрытые body.no-gamification:
испытания недели (#ch-section/.ch-widget), календарь стриков (.streak-cal),
стат-кольцо стрика (#sr-streak), монеты в профиле (#p-coins-row), чипы стрик/цель
на карточке питомца. Добавлены в CSS kill-switch (ls.css). Бэкенд: updateChallenges
и onLabExperiment писали прогресс/счётчики без проверки флага — добавлен гейт
isGamificationEnabled() (XP/coins/achievements уже гейтились в award*-функциях).

gamification/service.js (checkPhase3Achievements): новый био-блок —
bc_first_molecule (есть сохранённая молекула), bc_5_challenges (>=5 решённых),
bc_20_challenges (>=20) из таблиц bio_user_molecules / bio_user_challenges.
biochemController.js: после решения задачи и сохранения молекулы вызывается
checkAchievements(req.user.id) — раньше начислялся только XP, ачивки не
триггерились. Слоты bc_* существовали в _shared.js, но были мёртвыми.

When a teacher / admin turns off a module (per-class, per-role, or
globally), the matching achievements no longer clutter the user's
'Достижения' tab — but only the ones the user hasn't earned yet.
Already-unlocked achievements stay visible forever. We never take a
reward away after the fact.
Backend:
• migration 034 adds achievements.required_feature + backfills 42
rows (9 exam9, 8 red_book, 6 lab, 5 classroom, 4 textbooks, 3 each
of biochem/flashcards, 2 live_quiz, 2 pet). 32 core rows stay
NULL = always visible.
• middleware/features.js gains computeFeaturesForUser(userId, role)
+ isFeatureEnabledForUser — extracted from server.js#/api/features
so multiple consumers (gam achievements, future shop filter, etc.)
apply the same global+class+free_student merge.
• service.seedAchievements derives required_feature from track/group
when ACHIEVEMENT_DEFS doesn't spell one out, and UPDATE-syncs it on
every boot — keeps catalogue consistent across upgrades.
• _shared.getAllAchs SELECT now returns required_feature.
• gamification/api.getAchievements filters: drop locked rows whose
required_feature is === false for this user. Missing flag = ON
(opt-in disable model).
Verified: with exam9 + pet disabled, 12 locked achievements vanish from
the response while unlocked ones in those tracks remain.

Coins were always 1:10 of XP. Now they have their own event log + a
helper that dedups by reason within a configurable window.
Backend:
• migration 032 creates coin_log (user_id, amount, reason, created_at)
with indices for the 'fired today?' check
• awardCoins now records into coin_log on every call (reason defaults
to 'xp_bonus' for the legacy XP-proportional path)
• awardCoinsOnce(userId, amount, reason, window) — fires the bonus
only if no row matches in the window:
'day' → DATE(created_at) = today
'week' → ISO week match
'forever' → never twice
Wired events (Phase 4 subset of the plan):
• Daily login — 10 coins, once/day. Hooked in updateStreak so the
bonus rides on the existing 'daily_activity' XP trigger.
• Daily goal completion — 15/25/40 coins (easy/medium/hard), once/day.
Sits next to the existing tier XP bonus in updateDailyGoal.
• Variant clear — 30 coins, once per (user, variant) forever. Fires
from the exam-prep attempts endpoint when the user's final correct
answer fills out a math9 variant.
Deferred (need invasive trigger hooks): weekly goal, paragraph close,
boss defeated, referral.
Verified end-to-end: awardCoinsOnce returns true→false on repeated
calls, coin_log records the first, coins balance moves once.

Adds achievement coverage for every feature shipped since the original
seed: exam-prep (math9), textbooks, classroom/board, biochemistry,
live-quiz, flashcards, hangman/crossword, pet, plus a new 'social' group
for class & leaderboard wins and 'consistency' extensions (streak_100,
goal_30, early_bird, night_owl).
74 achievements now (was 36), grouped into 7 sections:
onboarding (3) → volume (8) → mastery (16) → consistency (7) →
exam (9) → exploration (21) → social (10)
A new top-level group 'exam' slots between consistency and exploration
in the profile UI.
What's wired in service.checkPhase3Achievements (called from
checkAchievements):
• streak_100 — extends the existing streak track
• goal_30 — 30 days with daily_goals fully met (SUM check)
• early_bird / night_owl — strftime('%H', xp_log.created_at)
• exam_first / 25 / 100 — exam_attempts where is_correct=1
• exam_variant_clear / 5_variants — perfect mock-variant sessions
• exam_topic_master — ≥10 attempts at ≥90% on a single subtopic
• exam_mock_done / pass / perfect — exam_mock_sessions.score
• tb_first_para — textbook_progress
• fc_first_deck / 100_cards / 1000_cards — flashcard_reviews
• bc_first_molecule / 5_challenges / 20_challenges — bio_user_*
• game_win_5 / 25 — xp_log reason IN (hangman_win, crossword_win)
• pet_streak_7 / 30 — users.pet_petting_streak
• lq_first / 3_quizzes — live_answers grouped by session
• cr_first_join / 5 / 25_lessons — classroom_attendance
• class_5_members / 25 — teacher's biggest class
• parent_link — parent_links presence
• lb_top10 / lb_top1 — weekly XP rank among students
What's deferred (catalog entry only, no trigger yet):
• tb_chapter_done / tb_book_done / tb_3_books — need to parse
textbook_progress.paragraphs_read JSON against textbook structure
Every block is wrapped in its own try/catch so a missing table on a
legacy install can't take down the whole achievement sweep.
Verified end-to-end: admin user picked up 7 new unlocks on first
checkAchievements call after seed.

Achievements gain four new columns: group_slug, track, tier, sort_order.
Existing 36 are backfilled into 5 groups (onboarding/volume/mastery/
consistency/exploration) by migration 030; 'social' stays empty until
Phase 3 adds class/leaderboard/live-quiz tracks.
Tracks bundle escalating thresholds into one progression (tests_10/50/
100 → track='tests', tiers 1-3), so the UI can show '★★★' on the top
tier and the user understands the relationship. sort_order is reserved
in blocks of 10 inside groups of 100, leaving room for inserts without
renumbering.
Backend:
• migration 030 adds the columns + index + backfill UPDATEs
• _shared.ACHIEVEMENT_DEFS gains group/track/tier/sort_order per row
• _shared exports new ACHIEVEMENT_GROUPS metadata for the UI
• service.seedAchievements writes the new fields on insert AND
backfills them via UPDATE on existing rows (fresh installs +
pre-migration installs both end up consistent)
• _shared.stmts.getAllAchs SELECT updated, ORDER BY sort_order
• gamification/api.getAchievements forwards the new fields
Frontend:
• profile.html groups achievements by group_slug with a per-section
header (icon + title + 'unlocked / total' chip) and a tier-star
badge (★★ etc.) on tier ≥ 2 items
• Hard-coded ACH_GROUPS mirror of the backend list (small, stable)
• New CSS for .ach-group / .ach-group-head / .ach-tier

Until now the 'gamification' feature flag did nothing: it had no row in
app_settings, the admin couldn't toggle it, awardXP/awardCoins ignored
it, and the CSS only hid three dashboard widgets — XP bars in textbooks
stayed visible regardless.
Phase 1 closes every hole.
Backend (source of truth):
• migration 029 seeds feature_gamification_enabled=1
• new isGamificationEnabled() helper in gamification/_shared.js with a
30s cache + invalidateGamificationCache() for instant admin toggles
• awardXP / awardCoins / updateStreak / unlockAchievement /
checkAchievements all bail out when the flag is off
• /api/gamification/* and /api/shop/* (user routes) return 404 when
disabled; admin routes remain open so the switch itself is reachable
• adminController.updateFeatures gains 'gamification' in the allow-list
and invalidates the cache on flip
Frontend:
• LS.isGamificationEnabled() (synchronous, populated by loadFeatures)
so xp.js + applyCosmetics can bail without a round-trip
• xp.js load/add/flush become no-ops when the flag is off
• applyCosmetics skips the round-trip when off
• CSS .no-gamification rule expanded to cover .hero-xp-badge, .po-xp,
.xp-card, .xp-bar, #frames-section, and a universal [data-gamified]
hook for future blocks
Textbooks (Variant 2 of the plan):
• backend/scripts/wrap_textbook_xp.py — idempotent script that adds
data-gamified to 167 XP tags across 63 textbook files (chapters +
hubs, all subjects/grades). Single CSS rule now hides everything.
Verified end-to-end: with the flag off, awardXP/awardCoins write nothing;
flipping back restores normal behavior.
