fix(worker): 独立 worker 启动加载 DB 设置——修复拆分部署下事件丢失与身份注入消失 - #512
Merged
Conversation
worker_main 此前只跑 pydantic 默认值，与 API 的 DB 生效设置分叉。生产 SESSION_EVENT_CHUNK_STORAGE_ENABLED=true 时：API 写 chunk、worker 走 legacy 内联，事件被 chunk 视图的 merge 覆写蒸发——刷新即丢整段对话历史 （2026-09-09 生产 P0，18:30Z 起全部会话 event_count=2）；SANDBOX_PLATFORM 同理回落默认，本地 daemon 身份段（#499）不再注入；token 统计同步失真。 修复：_amain 启动先 initialize_settings()（DB > env > 默认，对齐 API lifespan）再 validate_distributed_runtime_settings，失败快速退出由 CrashLoopBackOff 显性暴露，绝不带默认值吞事件。staging 复现验证： chunk=on + worker 拆分下事件完整落库（复现样本 event_count=2 → 修复后全量）。

Summary
独立 worker 进程（#507 拆分部署）此前不加载 DB 设置，只跑 pydantic 默认值，与 API 的生效设置（DB > env > 默认）分叉——2026-09-09 生产 P0 的根因。
事故链（生产 18:30Z 起全部会话受影响）
SESSION_EVENT_CHUNK_STORAGE_ENABLED=true：API 写 chunk 存储$pushevent_count=2（user:message + 零值 token:usage），刷新即丢整段历史；同一根因还导致SANDBOX_PLATFORM回落默认 → 本地 daemon 身份段（fix(prompt): 本地 daemon 会话注入「沙箱=用户本机」身份段 #499）不再注入staging 此前测不出的原因：staging DB 没开 chunk 开关（两边都 false，路径一致）。开启后 5 分钟内稳定复现（
event_count=2）。Fix
worker_main._amain启动第一步initialize_settings()+validate_distributed_runtime_settings(settings)，对齐 API lifespan（src/api/main.py:443）；失败快速退出，由 k8s CrashLoopBackOff 显性暴露——绝不带默认值继续吞事件。Testing
