From dff75a479e8d5eeff67fcc0e673b1ce5b30b31fe Mon Sep 17 00:00:00 2001 From: ruv Date: Fri, 12 Jun 2026 00:55:34 -0400 Subject: [PATCH] fix(homecore-automation): start engine + implement time/run-mode/choose/template (ADR-161 A3-A7) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
