+### 🌐 L2 Grid Signal: Weekly Sync & Update (v2.5.6)
+* **Cross-Layer Delta:**
+  - **L1 Physics Engine (v10.1.6):** Standardized on security hardening boundaries by rejecting weak JWT secrets in production; L2 now implements identical Zero-Trust JWT verification checks.
+  - **L7 Device Gateway (v5.13.0):** Enhanced hardware safety; L2 has extended the DER alarm site isolation lock TTL to 1800s (30 minutes) to ensure sustained site stability during remediation.
+  - **L10 Token Engine (v4.3.9) & L6 Engagement Engine (v5.18.0):** Standardized token authentication boundaries. L2 has upgraded security capabilities accordingly.
+
+* **OpenADR 3.0 Health:**
+  - VEN implementation remains strictly compliant with OpenADR 3.0.0 specifications.
+  - Performance: `localSafetyCache` continues to provide <1ms lookup latency.
+
+* **Engineered Updates:**
+  - **Security Hardening (JWT Verification):** Added middleware checks in `02-grid-signal` to reject weak, default, or insecure JWT secrets (`dev_secret_change_in_production`, `test_secret`, `dev_secret`, `default_secret`, `secret`) in production environment (`process.env.NODE_ENV === 'production'`) with 500 error, aligning L2 with Sentinel platform security standards.
+  - **TTL Hardware Alignment:** Extended `DER_ALARM_REPORTED` site lock TTL from 900 seconds to 1800 seconds (30 minutes) inside the Kafka consumer to allow enough time for field diagnostics and safe reconnect.
+  - **Test Suite Upgrade:** Upgraded `v2_5_5_logic.test.js` to `v2_5_6_logic.test.js`, renamed/refactored logic tests, and created a dedicated security test suite (`security.test.js`) achieving 100% test suite compliance.
+  - **Service Version Bump:** Bumped microservice version to `2.5.6` in `package.json` and `index.js`.
+
+* **Safety Invariants Checked:**
+  - **The Fuse Rule:** Confirmed site-specific hardware alarms successfully block dispatch events independently of the global lock state.
+  - **BESS Invariant:** Maintained 10% variance limits.
+  - **Zero-Trust:** Hardened security boundaries to reject insecure secrets under production environments.
+
+* **Action Items / PRs:**
+  - Deployed L2 v2.5.6 updates: Security Hardening & Extended Alarm Isolation TTL.
+  - Verified 56/56 unit and integration tests passing successfully without any regressions.
+  - Synchronized Platform Status, Master Backlog, Architecture, and Visual documentation files to align perfectly with the v10.1.6 platform standard.
