+DeltaX-Forge SWARM Agent Guide
+
+Overview
+- DeltaX-Forge is a cross-venue delta-driven execution planner with a canonical DSL and a two-tier solver architecture.
+- Core stack uses Python for production-grade components: a lightweight DSL, local venue solvers, a central curator, adapters for data feeds and execution, and a governance/logging layer.
+
+Project Architecture (high level)
+- deltax_forge_cross/
+  - __init__.py
+  - dsl.py           # Canonical StrategyDelta DSL (Assets, Legs, MarketSignal, PlanDelta, AuditLog) (see tests for usage)
+- deltax_forge_cross/core/
+  - local_venue_solver.py  # Local solver implementation
+  - central_curator.py       # Central coordination/consensus surrogate
+- deltax_forge_cross/adapters/
+  - price_feed_adapter.py    # Translates MarketSignal to a feed dict
+  - venue_execution_adapter.py  # Translates PlanDelta to an execution map
+- deltax_forge_cross/logging.py     # Deterministic replay logging
+- deltax_forge_cross/ledger.py      # Lightweight cryptographic signing (HMAC-based)
+- tests/                         # pytest suite (tests/test_deltax.py)
+
+Testing and CI
+- Test command: bash test.sh
+- test.sh builds, installs, and runs pytest
+- The tests exercise DSL, local/central solvers, adapters, and governance signing
+
+How to contribute
+- Run tests locally with: bash test.sh
+- Ensure new features have unit tests; keep changes minimal and well-scoped
+- Maintain backward compatibility unless explicitly required by a breaking change
+
+Notes
+- The repository is intentionally self-contained; it provides a minimal MVP for the DeltaX-Forge concept.

+# DeltaX-Forge: Cross-Venue Delta-Driven Execution Slicer (MVP)
 
-Source logic for Idea #149
\ No newline at end of file
+DeltaX-Forge provides a minimal, production-oriented blueprint for cross-venue hedging using a canonical StrategyDelta DSL, a two-tier solver, and deterministic governance logging.
+
+- Core DSL: Assets, Legs, MarketSignal, PlanDelta, and AuditLogEntry.
+- LocalVenueSolver: lightweight per-venue delta computation.
+- CentralCurator: cross-venue coherence and coordination.
+- Adapters: price feed and venue execution translations.
+- Deterministic replay and governance ledger via cryptographic signing.
+
+How to run tests locally
+- Ensure Python 3.11+ is available.
+- Run: bash test.sh
+- This will build, install, and run the test suite.
+
+Packaging notes
+- This repository is designed to be installed from a wheel or sdist. The test script installs the produced wheel before running tests to ensure import paths are resolvable in CI environments.
+
+Hooked commands
+- See AGENTS.md for developer-oriented information and testing commands.
