 - 验证：重启 worker 后日志应先出现“非 HTTP 进程跳过 SpacetimeDB 认证快照恢复”，随后出现 `external generation worker 已启动`；同一时间窗口不应再因为 `export_auth_store_snapshot_from_tables` 缺表而阻止 job claim。HTTP `api-server` 的认证恢复日志和 503 降级语义保持不变。

+## 本地旧 external-generation-worker 会抢队列并暴露成 procedure 超时
+
+- 现象：角色 / 画布生成的外部 provider 与 OSS 上传已成功，但 worker 写回 `editor_project_resource` 等业务资源时报 `SpacetimeDB procedure 调用超时`，日志里可能还能看到旧 worker 二进制对 procedure 返回值做 BSATN 反序列化失败。
+- 原因：本地 `npm run dev` / `npm run dev:api-server` 默认 `GENARRATIVE_PROCESS_ROLE=all`，会自己消费队列；如果之前手动启动的同仓库、同 database `GENARRATIVE_PROCESS_ROLE=external-generation-worker` 进程没有退出，旧二进制会继续 claim 新 job，schema / binding 已更新的当前进程反而没有拿到这次任务。
+- 处理：Linux 本地默认 `all` 角色启动前，`scripts/dev.mjs` 会扫描同仓库、同 SpacetimeDB server / database、同 `server-rs/target/debug/api-server` 的遗留 `external-generation-worker` 并停止；显式 `GENARRATIVE_PROCESS_ROLE=api` 做生产式拆分验证时不清理独立 worker。
+- 验证：`ps -eo pid,ppid,lstart,cmd | rg 'server-rs/target/debug/api-server'` 只应看到当前 `all` 或显式拆分下预期的进程；`/healthz` 和 `/readyz` 成功后，生成 job 应由当前进程消费并把业务资源写回。

 ## 外部生成 worker 业务写回必须同事务校验 lease guard
 
 - 现象：worker `complete/fail` 已校验 `worker_id + lease_token`，但如果玩法 session / work profile 写回在此之前单独调用，过期 worker 仍可能先写入业务状态，随后才在 job complete/fail 阶段失败；带计费包装的旧 worker 还可能因为 stale guard 错误触发补偿退款。

 Windows 本地如果已在 `%LOCALAPPDATA%\Genarrative\ffmpeg\bin` 安装 FFmpeg，`npm run dev` / `npm run dev:api-server` 会自动把该目录加入本次 `api-server` 子进程 `Path`，并注入 `CHARACTER_ANIMATION_FFMPEG_PATH` / `CHARACTER_ANIMATION_FFPROBE_PATH` 的绝对路径。这样即使外层终端或长期运行的 dev 进程是在安装 FFmpeg 之前启动，角色动画抽帧也不会继续因为 `ffmpeg: program not found` 失败；若手动配置了上述环境变量或 `GENARRATIVE_CHARACTER_ANIMATION_*` 前缀变量，显式配置优先。

 本地排查外部内容生成 worker 队列时，默认同一 Rust 进程同时监听 HTTP 并消费 `external_generation_job` 队列；更接近生产的验证应分别启动 `api`、`external-generation-worker` 和 `external-generation-controller`。生产默认 `GENARRATIVE_PROCESS_ROLE=api`，外部生成任务由独立 `GENARRATIVE_PROCESS_ROLE=external-generation-worker` 进程消费；生产与容器扩缩容验证保持 `queue`。当前进入持久队列的外部生成动作包括：拼图 `compile_puzzle_draft` / `generate_puzzle_images` / `generate_puzzle_ui_background`，跳一跳 `compile-draft` / `regenerate-tiles`，拼消消 `compile-draft` / `regenerate-atlas`，敲木鱼 `compile-draft` / `regenerate-hit-object`，以及图片画布 `editor_image_generation` / `editor_image_edit` / `editor_icon_spritesheet_generation` / `editor_ui_design_asset_extraction` / `editor_character_animation_generation` / `editor_video_generation` / `editor_sound_effect_generation` / `editor_background_music_generation`。非外部 provider 生成动作继续 inline，不进入队列。显式把本地进程角色设为 `api` 且没有 worker 时，HTTP 只返回 queued/running，不会兜底执行外部 provider。
