v0.1.20: 万世无谬（第二轮全量审计歼灭，1011 测试+双金钟罩）

【事件闸（机制重锤）】
- fire(w,id,priority)：单闸+优先级——高优（raid/渡劫/大比）顶替被占者、被顶替入 eventQueue 下月兑现不丢失；普通被占返回 false 调用方冷却（raid 被吞也写 CD）
- pending 唯一写入入口：渡劫/破境丹改走 fire（防覆盖丢弃）；名宿传薪年锚 flag（防同年重复 12 次）
- applyEventChoice 前置校验 pendingEvent===id（陈旧 Modal 二次结算防线）

【世界模型四修（真·活世界）】
- era 延续档：flow 权重和<1（留白=续任）——盛世能撑 30 年而非固定 25
- 潮汐供给符号修正：灵涨万物丰（原实现反了）＋tide 双界 clamp
- driftMarket 弱锚定：rebalance 0.1→0.025——供需/era/灾年真实撬动价格（原五池被锚死±5%）
- 断供/池底单常量 poolFloorPct=0.35（消灭禁买暗雷带）

【知识防线（审计虫洞修复）】
- 指纹扩展：era/stance/prosperity/relationsWithOthers/calamityLeft/pendingEvent 全入 hash
- 第二金钟罩 GOLDEN_RESOLVED：自动 resolve 长跑锁“现实”世界（原指纹锁的只是“事件流冻结”世界）

【性能与存储】
- 存档节流（疾12/常6/缓4，手动即时）+ saveChronicle O(N)→O(1) 单查增量写（2160 月档告别每 tick 数千 OPFS）
- battles≤220/chronicle≤520 截断（stringify 线性膨胀止血）；startNewGame/openState 停 timer 摘旧 bus

【杂项】actDirect 对齐 ACT_CATALOG 全 24 项；about 三版本统一 0.1.20；kernel.bus 死总线删；seed 改 RngHub.rollSeed；normalize 补 eraStartYear/overflux/distress；WorldPanel 买卖条件反转修复；音效与视效同闸

【测试】1011 全绿（42 套件）：audit-0.1.20 9 例（事件闸/传薪/二次结算/era延续/潮汐符号/断供一致/弱锚定/指纹敏感）
