Fires once when the regime monitor shifts quadrant (regime index x early warning), so you don't have to watch the tab. Two guards against spam: - Hysteresis: each axis only flips once the value crosses its divider by a margin, so a point parked on a boundary keeps its quadrant instead of flip-flopping day to day. - Cooldown: a genuine change stays quiet for a few days after the last alert. Seeds the baseline silently on first run; reuses the existing Telegram dispatch + AlertLog. New per-trigger toggle in Admin → Alerts (on by default).
