## [2026-06-12] - Phase 2.0 Overreaction Scanner Overhaul (#ISSUE-008)

### Added
*   **Anomalies-Scanner API Overhaul**: Implemented strict `force-dynamic` settings on [/api/scanner/route.ts](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/app/api/scanner/route.ts), expanded the calculation pool to 120+ assets, and integrated the FMP Small-Cap stock-screener vector with a fallback list of 30 volatile small-caps.
*   **Interactive Diagnostic Drawers**: Added expandable sub-rows inside [ScannerDemo.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/scanner/ScannerDemo.tsx) featuring drop catalyst dropdown selectors (Earnings Miss, Systemic Selloff, Executive Shift, Regulatory Issue, Supply Chain) and real-time GJR-GARCH rebound gauge columns.
*   **Rebound Probability Math**: Incorporated real-time rebound probability calculations utilizing GJR-GARCH outlier scores and catalyst stress damping coefficients.

### Modified
*   **`QUANT_ROADMAP.md`**: Updated Section 1 and added Section 4.IV documenting the Rebound Probability Score model equations in BlockMath LaTeX.

### Active Bugs / Compile Status
*   **Active Bugs**: None.
