M8：天工阁、叩心与辰正——受托任务后台并行、叩心四约束、时态感知投影

- 天工阁域 domains/tiangong：backstage_tasks（委托包+验收标准+结果证据）；有限分解（parent 链）与受控并行（各自后台 Run）；子任务全终态级联父任务进入待验收；按证据 accept/reject
- kernel.start_backstage_run（kind=background_task）：loop 后台分支不占前台席位、与前台对话并行；断言放宽容纳无人物功能任务；结果只经回调回呈任务——无身份写入路径
- 叩心域 domains/kouxin：knocking_candidates（event/time_anchor/manual 触发 + 草稿 + 裁决快照）；四约束裁决（总开关→静默窗口【本地时区判定】→24h 频率→预算），dispatch 未过 429 且快照留痕；候选默认不自动发送；expire_stale 过期推进不触碰缘契
- 辰正 domains/zhengchen：temporal_context() 复用 time_sense 计算核（快照/农历/季节），产出【时态感知】投影段接入镜树生成 prompt（客观时间语境，不附情绪臆测——守一纪律）
- 退役：modules/goal_orchestrator|planner|perception|big_cycle、application/planning、services/governance|goal_persist、candidates 表链（imports 候选抽取 API 面）、goals/plans/agent_roster/perception_channels/big_cycles/旧候选表（迁移 009）；前端 admin goals/plans/agents/perception/world 页与六组件；governance 只留 GenerationPreferences；admin 治理面收敛为司命+百工两枢；pivots 健康以域表计数重建
- 验收（test_m8_tiangong 五用例）：后台任务无身份写入（记忆/魂籍/缘契零新增）；后台与前台并行；分解级联；叩心四约束逐项；不回应不降低关系（缘契维度/状态/版本零变化）
- 四套件：后端 345、前端 203、BFF 4、神识 5 包全绿（2 个预存环境失败不变）；迁移 009 净库干净
