 - Server.aggregate also supports an optional clip_norm parameter to clip all incoming updates prior to averaging, providing an additional privacy safeguard.
 - You can combine clipping with Gaussian noise (noise_scale) for stronger privacy guarantees.
 
+Enhancements added (Planning Lens MVP)
+- PlanDelta provenance fields: The PlanDelta data model now includes optional provenance metadata (timestamp, author, contract_id, signature) to support auditing and deterministic replay in offline/offline-first scenarios.
+- Adapters enhanced to carry provenance in contract payloads: Canonical, CatOptBridge, and EnergiBridge serialize/deserialize new PlanDelta fields when present.
+- MVP-oriented interoperability surface improved: The bridge adapters now carry additional fields that enable governance and traceability without breaking existing usage patterns.
+- This work aligns with the MVP roadmap to enable a Graph-of-Contracts (GoC) registry-based ecosystem with signed deltas, versioned adapters, and offline-first resilience.

 How to run tests:
 - This repository provides a test script via test.sh (see below).
