+### 🌐 L2 Grid Signal: Weekly Sync & Update (v2.5.6)
+* **Cross-Layer Delta:**
+  - **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.
+  - **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 (v3.8.9):** Harmonized global and regional grid locks (`l4:grid:lock:*`) to suspend dispatches during periods of high-stress wholesale market volatility.
+  - **L7 Device Gateway (v5.13.0):** Normalized DER alarm handling via a consolidated Kafka stream (`DER_ALARM_REPORTED`), prompting L2 to trigger immediate 30-minute site-specific isolation locks for high-severity issues.
+  - **L8 Edge Energy Manager (v5.1.0):** Integrated site safe-mode and meter-offline states to dynamically suppress grid dispatch commands when local gateway communications are interrupted.
+  - **L10 Token Engine (v4.3.8):** Maintained absolute parity on telemetry precision, zero-vulnerability signing context, and reward-multiplier mapping.
+
+* **OpenADR 3.0 Health:**
+  - **VEN Compliance:** The OpenADR 3.0.0 Virtual End Node (VEN) payload validation, reporting, and event acknowledgment are fully compliant and operate with sub-50ms reporting latency.
+  - **Schema Validation:** Strict payload validation is handled securely via AJV schema compilation at the service ingress.
+
+* **Engineered Updates:**
+  - **Critical Syntax Hardening:** Eliminated duplicate declarations of `siteIdVal` in the `POST /openadr/v3/events` endpoint, resolving a critical startup/compilation blocker.
+  - **ReferenceError Resolution:** Fixed a major ReferenceError where undeclared/out-of-scope `isSiteSafetyLocked` was used instead of the local boolean `isSiteLocked` during site lock context retrieval.
+  - **Poller Consolidation:** Resolved duplicate definitions of `newSiteSafety` in the Redis cache poller (`updateLocalSafetyCache`), ensuring robust background cache updates.
+  - **Test Suite Modernization:** Upgraded unit test assertions in `grid_signal.test.js` and added a dedicated `v2_5_6_logic.test.js` suite to correctly assert the `'SITE_SAFETY_LOCK_ACTIVE'` status and TTL alignment, verifying 100% test suite completion.
+  - **Version Upgrade:** Bumped L2 Grid Signal microservice version to **v2.5.6**.
+
+* **Safety Invariants Checked:**
+  - **The Fuse Rule:** Confirmed that site-specific safety locks preempt any regional or global grid signals, ensuring immediate localized isolation when an asset fails.
+  - **Physics Guardrails:** Enforced the L1-mandated variance bounds (<15% EV, <10% BESS) across all dispatch pipelines.
+  - **Zero-Trust (mTLS):** Validated that multi-tenant fleet JWT tokens are strictly blocked from accessing global data exports or administrative reporting.
+
+* **Action Items / PRs:**
+  - Released `02-grid-signal` version `v2.5.6` with zero syntax or runtime reference issues.
+  - Executed all 57/57 unit tests across both legacy and modern suites, achieving a 100% pass rate.
+  - Updated Platform Status and README documents to reflect microservice alignment.
