+## 4. Fallback Protection & Operational Transparency Levels
+The workstation enforces zero silent caching or historical data ingestion:
+*   **PEAD Drift Radar**: Uses a dynamic state flag `isLivePeadApi` to toggle status rendering.
+    *   *Green Badge (`🟢 LIVE EPS FEED`)*: FMP API endpoint responded with real-world quarterly reports (`isLiveApi: true`).
+    *   *Amber Badge (`⚠️ ARCHIV-DATEN (API OFFLINE)`)*: Live API timeout, failure, or developer shield fallback active (`isLiveApi: false`).

+## [2026-06-14] - PEAD Fallback Transparency Warning Graphic (#ISSUE-023-WARN)
+
+### Added
+*   **Transparency Flag Ingestion**: Refactored `fetchFmpEarningsSurprise` and `getSimulatedPEAD` in [/api/scanner/route.ts](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/app/api/scanner/route.ts) to return `isLiveApi: true` upon successful live API queries and `isLiveApi: false` on failure or simulated fallbacks.
+*   **Dynamic Warning Badges**: Declared a state hook `isLivePeadApi` in [ScannerDemo.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/scanner/ScannerDemo.tsx) and bound it to scan responses in `handleMarketScan`. Renders green `"🟢 LIVE EPS FEED"` and amber `"⚠️ ARCHIV-DATEN (API OFFLINE)"` status badges adjacent to the PEAD Drift Radar header title depending on the scan api status.

 *   **Phase 7.0: Live Time-Lock Resolution, Ensemble Map Fix & Multi-Asset Logging**
    *   *Features*: Disabled developer mock test clocks inside verification loop hooks. Configured strict real-time calendar locks (T+1 resolves after 24h, T+5 after 5d, T+10 after 10d). Corrected the ensemble mapping anomaly inside `getPredictionProb` by passing the active asset's ticker context parameter. Embedded a dynamic asset selector filter tab-bar above the Active Learning Feedback Loop table component, enabling isolated tracking and filtering of multi-asset predictions (BTC, ETH, SOL).
    *   *Status*: **Fully Operational (Production Lock)**.
+*   **Phase 8.0: Isolated PEAD Screener & Fallback Warning Graphic**
+    *   *Features*: Integrated zero-coupling Post-Earnings Announcement Drift (PEAD) Screener parsing reported vs. consensus EPS surprise vectors. Implemented an `isLiveApi` flag to detect and handle offline API or rate-limit simulated fallbacks. Mounted glassmorphic warning status badges (`🟢 LIVE EPS FEED` vs `⚠️ ARCHIV-DATEN (API OFFLINE)`) in the frontend header to prevent trading on historical cached data without operational awareness.
+    *   *Status*: **Fully Operational (Production Lock)**.
