Stage 3 of the layered refactor. Relocate the two scheduling components
into their own package so that domain / application / scheduling /
execution / infrastructure boundaries actually exist on disk.
- Add schedule/src/schedule/scheduling/__init__.py
- Move scheduler.py (232 lines) -> scheduling/scheduler.py
(byte-identical via diff; CronScheduler class name unchanged)
- Move orchestrator.py (946 lines) -> scheduling/orchestrator.py
(byte-identical via diff; DispatchOrchestrator + event constants
unchanged; NOT further split this round, per plan)
- service.py lines 39-40: import paths rewritten to the new module
- tests/test_janitor.py: rewrite the import + 5 patch() string targets
The 5 patch() targets ("schedule.orchestrator.session_scope" x3,
"schedule.orchestrator.asyncio.sleep" x2) were NOT caught by the
import-line grep — they patch module attributes at runtime and would
have become dead no-ops after the move (and would hard-raise once
the old module is deleted in stage 6). Rewriting them to
"schedule.scheduling.orchestrator.*" keeps the janitor tests meaningfully
exercising the new module.
- old flat scheduler.py / orchestrator.py left on disk; stage 6 deletes
them once all layers are extracted.
Validation:
- uv run --package schedule pytest schedule/tests -q: 18 passed
- uv run python -m compileall schedule/src: zero errors
- grep 'from schedule.(scheduler|orchestrator)\\b' (old paths): 0 matches
- grep '"schedule.orchestrator.' (old patch targets): 0 matches
- main.py / worker.py / domain/ / infrastructure/ / pyproject.toml
byte-identical to HEAD

Schedule Executor
独立调度执行服务，内置 APScheduler。
- Cron 任务持久化到 MySQL 的
apscheduler_jobs表； - FastAPI Backend 创建运行记录和 Outbox 事件后，通过 HTTP 尝试立即推送；
- HTTP 推送失败时，Executor 继续轮询 MySQL
outbox_events，保证任务不会丢失； - Executor 负责 DAG 节点派发、稳定版本执行、重试、状态推进和结果回写；
- 不依赖 Redis，MySQL 是调度状态与幂等状态的唯一权威。
