NDB2 prediction lifecycle, drivers (date vs event), statuses, snooze checks, monitors, and public betting rules. Use when changing domain behavior around predictions, triggers/closes, snooze/votes, monitors under app/src/domain, or API/schema fields tied to lifecycle; read docs/game-mechanics.md first.
默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/Off-Nominal/ndb2 --skill ndb2-game-mechanics命令会保持在同一行。复制前请横向滚动并检查完整内容。

docs/game-mechanics.md — canonical product + schema mapping.app/src/domain/predictions/config.ts (trigger/snooze/judgement schedules; business-hours UTC vs 24/7 judgement).db/schema.sql — prediction_status, prediction_driver; tables predictions, bets, votes, snooze_checks, snooze_votes.predictions is column user_id; v2 queries often alias predictor_id; API exposes predictor.predictions.status is derived by trigger refresh_prediction_status() (see denormalized-data skill / docs/denormalized-data.md). Do not treat status as a free-form string: enum values are open, checking, retired, closed, successful, failed (not failure).snooze_checks row (closed = false) exists for the prediction, not only “check_date passed.”date: due_date; automatic close when due passes (subject to monitor schedules).event: check_date; no automatic close from due; stays open until triggered; check-in creates snooze_checks.open (product); bet edit window uses GM_PREDICTION_UPDATE_WINDOW_HOURS (12h production).snooze_votes (values 1, 7, 30, 90, 365 days). ≥3 votes on one option closes the check and pushes check_date.triggered_date, often longer.game-mechanics.md.due_date wall-clock.status in application code instead of setting the timestamps / rows the triggers use.checking with calendar check_date without an open snooze_checks row.
