 # DeltaForge Skeleton
 
-A production-oriented MVP scaffold for a real-time cross-venue delta-hedge engine.
+DeltaForge MVP skeleton: a real-time cross-asset strategy synthesis engine prototype.
 
-- Core DSL: Asset, MarketSignal, StrategyDelta, PlanDelta, SharedSignals, DualVariables
-- Lightweight curator (ADMM-like) for cross-venue coherence
+- Core DSL: Asset, MarketSignal, StrategyDelta, PlanDelta
+- Lightweight ADMM-like coordinator: ADMMCoordinator
 - Two starter adapters: equity_feed and options_feed
-- Minimal ExecutionEngine to route actions across venues
-- Toy Backtester with deterministic replay
-- Packaging metadata and test harness to verify packaging and end-to-end flow
+- Minimal execution adapter: ExecutionEngine
+- Toy backtester: Backtester with deterministic replay
+- Registry placeholder: GoCRegistry
+  - Lightweight in-memory Graph-of-Contracts (GoC) registry for versioned adapters and replayable messages.
+  - Basic primitives: GoCContract descriptor, GoCRegistry with register/get/list APIs.
+- Interoperability notes
+  - The MVP includes a minimal GoC registry and contract sketch to bootstrap interoperability between venue adapters and the canonical IR.
+  - This enables future mapping to LocalProblem/SharedSignals/PlanDelta with dual variables, cryptographic tags, and versioned contracts.
+- Packaging: pyproject.toml, ready for publication as deltaforge-skeleton
 
-How to run tests
-- python3 -m build
-- pytest (if pytest is installed) or python3 -m unittest discover -s deltaforge_skeleton/tests
+Usage (high level):
+- Create assets and signals with the DSL
+- Compose PlanDelta with StrategyDelta entries
+- Run ADMMCoordinator.reconcile(plan) to enforce cross-venue coherence
+- Use ExecutionEngine to route actions to venues
+- Run Backtester.replay(signals, plan) to simulate PnL deterministically
 
-This skeleton is designed to be extended into a full MVP within the DeltaForge ecosystem.
+This is a production-oriented skeleton intended to be expanded into a full MVP.
 
-Production-grade MVP improvements (overview):
-- Graph-of-Contracts (GoC) registry and versioned data schemas to enable cross-venue interoperability.
-- ADMM-like coordination layer (ADMMCoordinator) to enforce cross-venue coherence with a simple, auditable protocol.
-- EnergiBridge-inspired interoperability: primitives to IR mappings via the existing GoC registry.
-- Two starter adapters (equity_feed and options_feed) plus a minimal execution adapter and toy backtester, all wired for deterministic replay.
-- Packaging and publishing readiness: ready-to-publish signal (READY_TO_PUBLISH) and a market-facing README describing the architecture for external use.
+See src/deltaforge for implementation details.
