+Agent SWARM Architecture (High-Level)
+
+- Objective: Build a verifiable, DSL-driven federated economy toolkit for MMOs with offline-first capabilities and governance audit trails.
+- Tech Stack: Python-based core libraries for the MVP, with optional adapters for Unity/Unreal engines; cryptographic attestations simulated via deterministic hashes for testability.
+- Core Modules:
+  - dsl.py: Lightweight algebraic DSL parser and flow compiler.
+  - __init__.py: Public API surface re-exporting DSL functions.
+- Testing: Pytest-based tests verify DSL parsing, flow compilation, attestations, and DP-safe aggregation.
+- How to run:
+  - test.sh runs pytest and python -m build to validate packaging; see README for details.
+
+Architecture Rules:
+- Keep changes minimal and backwards compatible.
+- Use deterministic, testable crypto proofs in MVP; no real crypto dependencies required for the MVP.
+- The repository is a kata-like scaffold for the MVP; iterate with RFCs for extensibility.

+# GameEconomy Forge: Verifiable DSL-Driven Federated Economy
 
-Idea: A novel, open-source platform to coordinate cross-server virtual economies in massively multiplayer online (MMO) games using a math-friendly DSL and contract-driven federation. The goal is to align in-game pricing, item scarcity, loot drops, an
\ No newline at end of file
+This repository contains a minimal, working MVP of a verifiable, DSL-driven federation toolkit for MMO game economies. It demonstrates core ideas from the proposal, including:
+- A lightweight Algebraic DSL parser and flow compiler (DSL -> Flow)
+- Verifiable execution graphs with deterministic attestations
+- Simple secure aggregation (with optional DP-like noise)
+- A small Graph-of-Contracts registry placeholder
+
+This MVP is designed to be extended in subsequent iterations by additional agents in the SWARM, with a focus on minimal, well-tested, and safe changes.
+
+Project structure overview:
+- gameeconomy_forge_verifiable_dsl_driven_: Python package implementing the DSL and helpers
+- tests/: Pytest tests validating the core features
+- AGENTS.md: Architecture notes for future contributors
+- pyproject.toml: Build metadata for packaging
+- test.sh: Centralized test runner that also validates packaging
+- README.md: This document
+- READY_TO_PUBLISH: Placeholder created after a successful publish-ready state
+
+Execution and testing:
+- Run locally with: ./test.sh
+- Packaging verification: python3 -m build
+
+Note: This is an intentionally small, composable MVP—future work should add more robust DSL features and adapters for engines (Unity/Unreal/etc).
+
+Longer-term goals align with the original concept but are out of scope for this initial MVP.
