+# L4 Market Gateway Weekly Report - April 2026 (Week 5)
+
+## L4 Health & Dependency Report
+
+The L4 Market Gateway has been upgraded to **v3.8.6** to achieve full architectural parity with the latest hardening in the MiGrid 10-layer stack. This release focuses on robust telemetry parsing, high-fidelity score synchronization with L3, and standardized multi-site identification.
+
+*   **L1 Physics Engine (v10.1.4):** L4 v3.8.6 now implements strict `isNaN` protection for physics and confidence scores, ensuring that telemetry remains deterministic even in edge-case network conditions.
+*   **L3 VPP Aggregator (v3.3.2):** The `BiddingOptimizer` has been enhanced to extract and utilize the high-fidelity `physics_score` and `confidence_score` provided by L3's regional capacity breakdown.
+*   **L10 Token Engine (v4.3.6):** Standardized on the `extractSiteId` helper for multi-key site identification, ensuring market price broadcasts are perfectly aligned with L10 site-aware reward logic.
+
+## Backlog Updates
+
+| Task ID | Description | Priority | Status |
+|:---:|:---|:---:|:---|
+| **L4-NAN-HARDEN** | Implement `isNaN` protection for all incoming and outgoing telemetry scores. | **P0** | COMPLETED |
+| **L4-L3-HF-SYNC** | Synchronize `BiddingOptimizer` audit metadata with L3 high-fidelity regional context. | **P0** | COMPLETED |
+| **L4-SITE-PARITY** | Integrate `extractSiteId` helper for cross-layer site identification parity. | **P1** | COMPLETED |
+| **L4-AI-AUDIT** | Standardize string-formatted scores (.toFixed(4)) for L11 ML Engine audit trails. | **P1** | COMPLETED |
+
+## Engineering Execution
+
+The transition to L4 v3.8.6 involved the following core technical updates:
+
+1.  **Robust Telemetry Parsing:** Refactored Kafka consumers in `index.js` to include explicit `isNaN` checks and `.toFixed(4)` string formatting for all scoring metrics.
+2.  **High-Fidelity Score Extraction:** Updated `BiddingOptimizer.js` to retrieve `physics_score` and `confidence_score` from the `vpp:capacity:regional:high_fidelity` Redis key, prioritizing ground-truth data from L3.
+3.  **Site Identification Parity:** Deployed the `extractSiteId` helper in `index.js` to support `site_id`, `siteId`, `location_id`, and `locationId` keys across all grid signal processing.
+4.  **Audit Trail Hardening:** Standardized the audit metadata generated during bid optimization to ensure deterministic data availability for Phase 6 AI training.
