 ### 🌐 L2 Grid Signal: Weekly Sync & Update (v2.5.6)
 * **Cross-Layer Delta:**
-<<<<<<< HEAD
-  - **L1 Physics Engine (v10.1.6):** Maintained strict alignment with physics invariant locks (<15% variance threshold for EV, 10% threshold for BESS) and zero-trust JWT authentication rejection.
-  - **L4 Market Gateway (v3.9.0):** Synchronized on sub-millisecond regional grid lock cache polling and JWT secret safety checks.
-  - **L5 Driver Experience API & L10 Token Engine (v4.3.9):** Maintained parity in zero-trust production JWT authentication hardening.
-  - **L7 Device Gateway (v5.13.0):** Hardware alarm bridge active with 1800-second TTL site safety locks for critical/high DER hardware alarms.
-
-* **OpenADR 3.0 Health:**
-  - VEN implementation remains strictly compliant with OpenADR 3.0.0 specifications.
-  - Performance: `localSafetyCache` provides sub-millisecond safety lock checks before signal dispatch.
-
-* **Engineered Updates:**
-  - **Microservice Version Upgrade:** Upgraded `02-grid-signal` from v2.5.5 to v2.5.6 in `package.json` and `index.js`.
-  - **Zero-Trust JWT Security Hardening:** Refactored `authenticateToken` middleware in `index.js` to reject weak, default, or insecure secrets (`dev_secret_change_in_production`, `test_secret`, `dev_secret`, `default_secret`, `secret`) in production environments (`NODE_ENV=production`) with a 500 configuration error (`INTERNAL_CONFIGURATION_ERROR`).
-  - **Security Unit Testing:** Created `security.test.js` validating weak secret rejection and production security behavior under Jest.
-
-* **Safety Invariants Checked:**
-  - **The Fuse Rule:** Site-level and regional safety locks operate independently of cloud connection state, maintaining edge-level resilience.
-  - **BESS Invariant:** Maintained 10% variance threshold for stationary storage and 15% threshold for EV charging.
-  - **Zero-Trust Security:** Verified all endpoints enforce production key validation and reject weak secrets.
-
-* **Action Items / PRs:**
-  - Generated L2 v2.5.6 release: Zero-Trust Production JWT Hardening & Microservice Parity.
-  - Verified 100% test suite compliance (56/56 tests passing across `security.test.js`, `v2_5_5_logic.test.js`, and `grid_signal.test.js`).

-=======
-  - **L1 Physics Engine (v10.1.6):** Synchronized with high-fidelity telemetry validation enforcing the strict <15% variance threshold for EV charging sessions and 10% for stationary BESS assets; standardized on security hardening boundaries by rejecting weak JWT secrets in production.

   - **L3 VPP Aggregator (v3.3.3):** Streamlined sub-500ms reporting by importing aggregated regional capacity breakdowns (EV/BESS) and average regional confidence scores.
   - **L4 Market Gateway (v3.9.0):** Harmonized global and regional grid locks (`l4:grid:lock:*`) to suspend dispatches during periods of high-stress wholesale market volatility, and aligned on JWT secret safety checks.
   - **L7 Device Gateway (v5.13.0):** Normalized DER alarm handling via a consolidated Kafka stream (`DER_ALARM_REPORTED`), extending the DER alarm site isolation lock TTL to 1800s (30 minutes) to ensure sustained physical site stability during remediation.
