-## Latest Release Wins (April 2026)
+## Latest Release Wins (June 2026)
 
-- **L1 Physics Engine (v10.1.5)**: Implemented **localSafetyCache [L1-133]** for sub-millisecond resilience and achieved Phase 6 telemetry parity via strict `.toFixed(4)` string formatting.
-- **L7 Device Gateway (v5.11.0)**: Deployed **localSafetyCache [L7-133]** for resilient dispatch; hardened DER alarm handling via OCPP 2.1 `NotifyDERAlarm` broadcasting.
-- **L10 Token Engine (v4.3.7)**: Standardized asynchronous **Reward Batching** worker and hardened site identification via `extractSiteId`.
-- **L4 Market Gateway (v3.8.7)**: Enforced high-fidelity telemetry standards with `safeFloat` utility and strict string-formatted auditing for ML parity.
-- **L2 Grid Signal (v2.5.3)**: Hardened telemetry parsing with `isNaN` protection and aligned scoring outputs with L11 AI standards.
-- **L6 Engagement Engine (v5.17.0)**: Standardized site identification and enforced strict string-formatting for all physics and confidence scores.
+- **L1 Physics Engine (v10.1.6)**: Standardized `isNaN` protection across physics metrics and confidence scores using the `safeFloat(val, fallback)` utility [L1-136].
+- **L7 Device Gateway (v5.13.0)**: Optimized heartbeat hash indexing (`l7:heartbeats`) and enhanced hardware availability tracking via standardized 4-decimal telemetry.
+- **L10 Token Engine (v4.3.8)**: Implemented 'Hardware Health Penalty', reducing reward multipliers based on regional alarm density from L4 v3.8.9.
+- **L4 Market Gateway (v3.8.9)**: Implemented hardware-aware bidding confidence logic, deducting score based on active regional DER alarms reported from L7.
+- **L2 Grid Signal (v2.5.5)**: Implemented **sub-millisecond site-specific lock synchronization** and standardized 4-decimal string telemetry for L11 ML parity.
+- **L6 Engagement Engine (v5.18.0)**: Standardized `safeFloat(val, fallback)` utility and deployed 'Hardware Health Guardian' achievement.

+### 🌐 L2 Grid Signal: Weekly Sync & Update (v2.5.5)
+* **Cross-Layer Delta:**
+  - **L1 Physics Engine (v10.1.6):** Standardized `isNaN` protection and 4-decimal telemetry for L11 ML parity.
+  - **L4 Market Gateway (v3.8.9):** Implemented hardware-aware bidding confidence shifting based on regional DER alarms.
+  - **L7 Device Gateway (v5.13.0):** Optimized heartbeat hash indexing and normalized individual DER alarm broadcasts for L4 parity.
+  - **L10 Token Engine (v4.3.8):** Integrated 'Hardware Health Penalty' logic for site-aware rewards.
+
+* **OpenADR 3.0 Health:**
+  - VEN implementation remains strictly compliant with OpenADR 3.0.0.
+  - Resilience: `localSafetyCache` now handles site-specific locks with <1ms lookup latency.
+
+* **Engineered Updates:**
+  - **Site-Specific Safety Locks [L2-v2.5.5]:** Expanded `localSafetyCache` and `updateLocalSafetyCache` to synchronize and enforce site-specific safety locks from Redis (`l1:safety:lock:site:*`).
+  - **Standardized Telemetry:** Refactored `safeFloat` utility and background aggregation tasks to enforce strict string-formatted 4-decimal telemetry (.toFixed(4)) for Phase 6 ML readiness.
+  - **Granular Dispatch Control:** Updated `POST /openadr/v3/events` to reject signals for sites with active physics violations or critical hardware alarms.
+  - **Reporting Enrichment:** Enhanced `GET /openadr/v3/reports` to include site-specific safety states and strictly formatted metrics.
+
+* **Safety Invariants Checked:**
+  - **The Fuse Rule:** Confirmed site-specific locks correctly preempt dispatch even if global/regional locks are inactive.
+  - **Physics Thresholds:** Maintained 10% (BESS) and 15% (EV) variance thresholds with sub-millisecond enforcement.
+  - **Zero-Trust:** Verified global reports remain restricted to system-level tokens.
+
+* **Action Items / PRs:**
+  - Deployed L2 v2.5.5: Site-Specific Resilience & 4-Decimal Telemetry Hardening.
+  - Verified 46/46 unit tests passing, including new site-lock regression tests.
+  - Updated `PLATFORM_STATUS.md` to reflect June 2026 v10.1.6 ecosystem standard.
