Канон PRODUCT-AI (Spec#22): пилотные метрики L1-подсказок для расчёта
голосового гейта L2 (>=20% активных пользователей с >=2 подтверждённых
ghost-бронирований в месяц). Локальные счётчики в Mnesia, без LLM.
- таблица ai_hint_metric (миграция 20260820180000): счётчики
{user, день UTC, pattern, kind}; ленивый prune при >500 строк на
пользователя, retention 92 дня
- POST /v1/ai/hint-metrics (Bearer): батч <=20 событий shown/confirm/dismiss,
202 {accepted:N}; ETS rate limit 30 req/min на пользователя
- GET /v1/admin/ai-metrics/stats (админ-порт): by_kind, active_users_30d,
users_with_confirms_ge2_30d, gate_ratio_30d, top_patterns_by_confirm
- eunit logic_ai_metrics_tests (5/5); синхронизация списка миграций
в migration_engine_tests
