 - Secure Transport: basic channel abstraction with key rotation stubs.
 - Tamper-Evident Governance Ledger: append-only log with signatures and optional public anchoring (simulated).
 - Delta-Sync: state reconciliation with proof checks.
+- EnergiBridge: canonical, vendor-agnostic bridge mapping GridGuard primitives to a CatOpt-inspired representation (Objects, Morphisms, PlanDelta). Enables cross-vendor interoperability.
+- Graph-of-Contracts registry: versioned schemas for adapters and data models; replay protection and auditability.
+- Attestation enhancements: DID-based identities and hardware-backed attestation binding to contract permissions.
+- Privacy-by-design primitives: secure aggregation and pluggable zero-knowledge proof stubs for verifiable compliance.
+- Post-quantum readiness: crypto-hygiene considerations and key rotation strategies.
+- Tamper-evident governance ledger: anchoring options to public ledgers for cross-organization auditability.
 - Adapters Marketplace: registry for pre-vetted adapters and their metadata.
 - Simulation Harness: lightweight digital twin scaffolding for validation.
