+- See docs/elac_plan_interop.md for a minimal DSL sketch and EnergiBridge-style interoperability planning (LocalProblem/SharedVariables/PlanDelta/DualVariables/AuditLog).

+- The plan includes phases for governance, secure aggregation, cross-venue demos, and HIL testing; reference SDK and sample DSL are provided for integration with other domains.

+ELAC-Plan Interoperability and DSL Sketch
+
+Overview
+- ELAC-Plan defines a canonical primitive set for cross-venue execution planning:
+- Objects/LocalProblem: per-asset, per-venue optimization tasks
+- Morphisms/SharedVariables: privacy-bounded market signals
+- DualVariables: cross-venue coupling signals (shadow prices)
+- PlanDelta: incremental plan updates with provenance metadata
+- AuditLog: cryptographic provenance and governance events
+
+Interoperability mapping ( EnergiBridge-style )
+- Map ELAC primitives to a simple, vendor-agnostic IR:
+  - LocalProblem -> Object: id, asset, venue, objective, constraints, price_target, tolerance
+  - SharedVariables -> Morphisms: contract_id, version, variables
+  - PlanDelta -> PlanDelta: delta, timestamp, author, contract_id, privacy_budget
+  - DualVariables -> DualVariables: contract_id, version, shadow_prices
+  - AuditLog -> AuditLog: entries with event, timestamp, hash, details
+
+Minimal DSL sketch (Python dataclasses used in tests)
+```python
+from dataclasses import dataclass
+from typing import Dict, Any
+
+@dataclass
+class DSLObject:
+  id: str
+  asset: str
+  venue: str
+  objective: str
+  constraints: Dict[str, Any]
+  price_target: float
+  tolerance: float
+
+@dataclass
+class DSLMorphisms:
+  contract_id: str
+  version: int
+  variables: Dict[str, Any]
+
+@dataclass
+class DSLDualVariables:
+  contract_id: str
+  version: int
+  shadow_prices: Dict[str, float]
+
+@dataclass
+class DSLPlanDelta:
+  contract_id: str
+  delta: Dict[str, Any]
+  timestamp: str
+  author: str
+  privacy_budget: float
+```
+
+Toy two-adapter MVP (Phase 0)
+- 2 starter adapters:
+  - NBBOFeedAdapter: translates NBBO-like quotes into SharedVariables (privacy-bounded)
+  - BrokerGatewayAdapter: publishes PlanDelta to a broker API (TLS transport conceptually)
+- Lightweight LocalSolver that consumes LocalProblem and emits PlanDelta
+- End-to-end delta-sync with deterministic replay on reconnects
+- Toy cross-venue objective (e.g., simple arb or spread capture)
+
+Phase plan (high level)
+- Phase 0: Protocol skeleton + 2 adapters + TLS; deterministic delta-sync; local objective
+- Phase 1: Governance ledger scaffolding; identity layer; adapter conformance checks
+- Phase 2: Cross-venue demo in simulated environments; reference ELAC SDK
+- Phase 3: Performance and privacy budget evaluation
+
+Security and governance principles
+- TEEs/isolations for edge solvers; per-message crypto-tags
+- Secure aggregation for SharedVariables; optional zk-proofs
+- Tamper-evident governance ledger anchored to a lightweight ledger or hash chain
+- DID-based identity certificates for adapters
+
+Testability and metrics
+- Latency: data feed -> plan delta at edge
+- Delta-sync turnaround and convergence speed
+- Plan quality vs centralized baseline
+- Privacy budget leakage budgets
+- Adapter conformance and governance coverage
+
+If helpful, I can draft concrete DSL sketches for additional primitives or extend the toy MVP with a lightweight TLS transport layer and simulated venues.
