## [2026-06-14] - Isolated PEAD Fundamental Momentum Screener Integration (#ISSUE-023)
### Added
* **Earnings Surprise Parsing & Parsing Fallbacks**: Implemented `fetchFmpEarningsSurprise` in [/api/scanner/route.ts](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/app/api/scanner/route.ts) to query quarterly EPS surprises. Implemented `getSimulatedPEAD` to deterministically simulate PEAD variables offline, preserving the `2026-06-14` date-lock.
* **SUE Momentum calculations**: Computes Earnings Surprise percent (using the consensus EPS expectation difference) and tracks days elapsed since announcement. Assigns `"Active Drift"` status if surprise absolute value exceeds 4.5% and time elapsed is under 45 days.
* **PEAD Drift Radar Workstation Grid**: Embedded a sub-tab layout in [ScannerDemo.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/scanner/ScannerDemo.tsx) housing the high-density glassmorphic "🚀 PEAD Drift Radar" table, mapping ticker/name, sector, release date, reported vs consensus EPS, surprise %, and drift momentum status. Bound to an isolated `peadData` react state hook.
