 How to contribution
 - Run tests via test.sh; ensure deterministic behavior.
 - Extend with new adapters, new assets, or richer DSL primitives.
+- MVP Skeleton (New)
+- Added a minimal Python-based DeltaForge MVP skeleton: core DSL (Asset, MarketSignal, StrategyDelta, PlanDelta), a simple Curator, two starter adapters (equity_feed and options_feed), a toy ExecutionEngine and Backtester.
+- Packaging: pyproject.toml and README.md to enable building and publishing the MVP skeleton as a package named deltaforge-skeleton.
+- Test harness: test.sh to run tests deterministically and validate end-to-end flow with a toy cross-venue hedge.
+- Ready-to-publish signal: READY_TO_PUBLISH file.

+# DeltaForge MVP: Real-Time Cross-Asset Strategy Synthesis (Skeleton)
-
-DeltaForge MVP: Minimal, open-source engine for real-time cross-asset hedging across options and equities across two venues.
-
-Overview
-- A compact DSL to declare strategy objectives (risk budgets, PnL targets, liquidity constraints).
-- Two starter adapters (equity feed and options market data).
-- Lightweight, two-venue risk solvers with a central curator for cross-venue constraints.
-- Minimal deterministic backtester and a toy execution adapter.
-- MVP runs in a small two-asset, two-venue scenario demonstrating delta-hedges and cross-venue spreads.
-
-Enhancements (as of this iteration)
-- DSL sketch for StrategyDelta, Asset, MarketSignal, PlanDelta to support plug-and-play adapters.
-- Lightweight ADMM-lite coordination with a shadow-fallback solver to handle disconnects gracefully.
-- Minimal cross-venue execution router (ExecutionRouter) to illustrate latency/fees-aware routing.
-- Two starter adapters (equity feed and options feed) that feed the canonical DSL and backtester.
-- Deterministic backtesting for reproducible hedges.
-- Documentation artifacts including dsl_sketch.md to guide future extensions.
-
-What’s included
-- Python package deltaforge_mvp with core DSL scaffolds and demo flow.
-- Adapters: deltaforge_mvp/adapters/equity_feed.py, deltaforge_mvp/adapters/options_feed.py
-- Venue coordination: deltaforge_mvp/coordination.py (ADMM-lite style coordination skeleton)
-- Backtester: deltaforge_mvp/backtester.py
-- Demo: deltaforge_mvp/demo.py (orchestrates a simple delta hedge across two venues)
-- Tests: tests/test_demo.py
-- Test script: test.sh
-- Metadata: AGENTS.md (architecture guide) and READY_TO_PUBLISH placeholder
-
-How to run (locally)
-- Build and install: python -m build
-- Run demo: python -m deltaforge_mvp.demo
-- Run tests: bash test.sh
-
-Note: This is a minimal, initial MVP skeleton intended to bootstrap discussion and future extension. It focuses on the core concepts with simple deterministic flows.
-
-Usage notes:
-- The MVP uses a tiny Python package deltaforge_mvp with a demo orchestrator and two starter adapters.
-- To run the demo: python -m deltaforge_mvp.demo
-- To execute tests: bash test.sh
