A3 (HIGH): homecore-server constructed AutomationEngine then dropped it
immediately while the doc claimed automation was active. Now .start()s the
engine into a long-lived binding (event loop + timer task).
A4 (HIGH): Trigger::Time was hard-coded false with no timer. Added a 1 Hz
wall-clock timer task that fires time: automations when local HH:MM:SS matches
'at' (HH:MM or HH:MM:SS); matches_sync(Time)=false is now correct + documented.
A5 (HIGH): RunMode was documented as AtomicBool-enforced but every trigger
spawned unbounded parallel. Each automation now carries a running AtomicBool;
Single/IgnoreFirst skip re-entrant triggers, Parallel fires every time.
(Bounded Queued/Restart/max → ACCEPTED-FUTURE, honestly stated in the doc.)
A6 (HIGH): Action::Choose discarded choices and always ran default. Now
deserialises each branch's conditions, evaluates them, and runs the first
matching branch; default only if none match.
A7 (MEDIUM): template: conditions were always false in the engine path
(EvalContext built with template_env: None). The engine now builds a
TemplateEnvironment over the state machine and threads it into every
EvalContext (event loop, timer, Choose).
Tests (fail on old source):
- engine_behaviors::time_trigger_fires_via_timer_path (A4)
- engine_behaviors::single_mode_does_not_double_fire_on_rapid_triggers (A5; old fired 2x)
- engine_behaviors::parallel_mode_does_fire_concurrently (A5)
- action::choose_runs_matching_branch_not_default (A6; old ran default)
- engine_behaviors::template_condition_evaluates_true_in_engine (A7; old always false)
engine.rs kept <500 lines; behavioral tests moved to tests/engine_behaviors.rs.
