Begins the lift of `web_server._register_automation_handlers` (1530
lines, 20 nested closures) into `core/automation/handlers/`. Each
extracted handler is a top-level function that accepts
`(config, deps)` instead of reaching for module-level globals --
makes them unit-testable in isolation.
Infrastructure:
- `core/automation/deps.py`: `AutomationDeps` (dependency-injection
bundle of clients + callables) and `AutomationState` (mutable flags
shared across handler invocations, with thread-safe accessors).
- `core/automation/handlers/__init__.py` + `registration.py`: one-stop
`register_all(deps)` that wires every extracted handler to the
engine.
First batch of handlers extracted:
- `process_wishlist` -> `core/automation/handlers/process_wishlist.py`
- `scan_watchlist` -> `core/automation/handlers/scan_watchlist.py`
- `scan_library` -> `core/automation/handlers/scan_library.py`
`web_server._register_automation_handlers` now builds the deps once
and calls `register_all(deps)` for the extracted batch. Remaining
17 closures still live below; subsequent commits in this branch
finish the lift.
14 boundary tests in `tests/automation/test_handlers_simple.py` pin
every shape: success path, exception swallow contract, fresh-vs-stale
state detection (scan_watchlist's id() trick), guard short-circuits,
state cleanup on exceptions, AutomationState concurrent-safe accessors.
All 101 automation tests pass; no regression.
