-ML-driven cross-venue hedge synthesis MVP skeleton
+This repository provides a minimal, production-oriented scaffold for an ML-driven cross-venue hedge synthesis engine. The MVP includes core DSL primitives, a toy hedge synthesis engine, and lightweight adapters to bootstrap interoperability.
 
-This repository provides a production-oriented skeleton for an ML-augmented cross-venue hedge synthesis engine. It includes a canonical DSL, deterministic delta replay, toy adapters, and a minimal hedge engine to bootstrap MVP development.
+What you can find here:
+- Core DSL: Asset, MarketSignal, RiskState, HedgePlanDelta, GraphOfContracts
+- Hedge engine: HedgeSynthesisEngine with a simple Budget model
+- Adapters: PriceFeedAdapter (toy) and OptionsVenueAdapter (stubbed)
+- Delta-sync: deterministic replay placeholder
 
-How to run
-- Install dependencies and tests: see test.sh
-- Run tests: ./test.sh
+How to run tests:
+- Install dependencies: python3 -m pip install -r requirements.txt
+- Run: pytest
 
-Architecture overview
-- Core primitives: Asset, MarketSignal, RiskState, HedgePlanDelta, GraphOfContracts
-- Engines and adapters to enable cross-venue hedging experiments
-- Delta-sync for deterministic replay
-- MVP plan in repository: two assets, two venues, two toy adapters
+Build packaging:
+- Run: python3 -m build
+
+This is a starting point. The MVP can evolve toward a full ML-driven cross-venue hedging engine with privacy-preserving signal sharing and delta-sync guarantees.
