Situation Monitor: News Signal

Triggers when the Situation Monitor classifies a matching market signal (news, on-chain event, technical breakout, macro, earnings, M&A, hack/exploit, etc.). Optionally filter by tickers, event types, minimum absolute impact (0-10, default 4), confidence tier (high|medium|low, default high), or scope (asset|sector|market).
