/**
 * evolveTrigger - Task 4, G2 (the learning Kagemusha deferred forever).
 *
 * An intervention outcome (succeeded / failed / corrected) is fed to the trigger's stats,
 * then the AGENT decides whether to keep, refine, or retire the trigger. The decision is
 * INJECTED (`decide`) - the real one is an LLM call. There is deliberately NO numeric
 * threshold in this module: a fixed `if (failed >= N) disable()` would be exactly the
 * automation trap that re-freezes G2. The same stats can be kept or retired by judgment.
