-- Canonical primitives form the Covariant IR for cross-venue execution provenance:
+- Core primitives:
-  - LocalExecutionTask: per-instrument, per-venue planning unit
+  - LocalExecutionTask: per-instrument, per-venue execution task
-  - SharedMarketContext: privacy-safe, versioned market signals
+- SharedMarketContext: versioned market signals across venues
-  - PlanDelta: incremental routing/size/timing decisions with metadata
+- PlanDelta: incremental routing/size/timing decisions with metadata
-  - Attestation/AuditLog: cryptographic attestations and append-only logs
+- Attestation/AuditLog: cryptographic attestations and an append-only log
-  - Graph-of-Contracts: adapters and data-contract schemas
+- Graph-of-Contracts: registry for adapters and data contracts
-- Edge-native solver: lightweight optimizer co-located with venue data to produce PlanDelta
-- Delta-sync with deterministic replay for offline backtesting and regulatory review
-- Governance ledger: cryptographic signing, policy hooks, optional cloud anchoring
-- Adapters marketplace: plug-in venue adapters translating venue data into canonical IR
 
-MVP plan (8–12 weeks)
+Development workflow
-- Phase 0: Skeleton protocol, 2 starter adapters, toy objective (VWAP-like), deterministic delta-sync
+- Use Python as the MVP language for the core primitives.
-- Phase 1: Governance scaffolding, identity management, secure aggregation for SharedMarketContext
+- Tests live under tests/ and are executed via test.sh.
-- Phase 2: Cross-venue demo in simulated env; publish ExProve SDK and minimal contract example
+- Packaging uses pyproject.toml with a standard build-system block.
-- Phase 3: Backtesting harness and deterministic replay; compliance-report generator
 
-Deliverables
+Validation
-- Core data contracts: LocalExecutionTask, SharedMarketContext, PlanDelta, Attestation, AuditLog, Graph-of-Contracts
+- Ensure test.sh runs: pytest and python3 -m build (to validate packaging).
-- Toy adapters (2 starters) and conformance harness
+- Maintain deterministic behavior for replayability in tests where applicable.
-- Seed DSL for LocalExecutionTask/SharedMarketContext/PlanDelta
-- Reference ExProve SDK (Python/C++ bindings) and transport layer
 
-Testing and QA
+Contribution
-- Lightweight conformance harness and toy adapters (end-to-end replay tests)
+- Add small, well-scoped changes. Update tests accordingly.
-- Deterministic tests for PlanDelta generation
+- Document public API in README.md and inline comments where necessary.
-- Audit-ready logs and crypto tagging (signatures stubs for MVP)
 
-Repository rules
+This file documents the architectural rules and contribution guidelines for ExProve in this repository.
-- Use Python for core MVP; keep dependencies minimal
-- Add test.sh that builds and runs tests; ensure python packaging compiles
-- If you add external dependencies, update pyproject.toml and keep tests deterministic
-
-Contributing
-- Follow the existing coding style in this repo; keep changes minimal and well-scoped
-- Add tests for any bug fixes or new primitives
-- Update README with usage notes and contributor guidelines

-# ExProve: Open-Source Execution Provenance Engine for Cross-Venue Equity Trading
+# ExProve Open-Source Execution Provenance Engine
 
-ExProve provides a minimal, production-oriented MVP for verifiable cross-venue execution provenance.
+ExProve provides cryptographically verifiable provenance primitives for cross-venue execution decisions in equity trading. This repository implements core data contracts and a deterministic planning primitive suitable for testing, backtesting, and regulatory review workflows.
 
-- Core primitives: LocalExecutionTask, SharedMarketContext, PlanDelta, Attestation, AuditLog, GraphOfContracts
+Key Primitives
-- Edge-native planner: deterministic PlanDelta generation for replay and backtesting
+- LocalExecutionTask: per instrument/venue planning unit
-- Deterministic delta-synchronization for offline replay
+- SharedMarketContext: privacy-safe, versioned market signals
-- Python-based MVP with a small test suite and packaging metadata
+- PlanDelta: incremental routing/size/timing decisions with metadata
+- Attestation/AuditLog: cryptographic attestations and an append-only log
+- GraphOfContracts: registry for adapters and data-contract schemas
 
-- How to run
+How to use
-  1. Install dependencies via pyproject.toml (build uses setuptools)
+- Install dependencies and run tests via the provided test script (test.sh).
-  2. Run test script: bash test.sh
+- The core models are defined under exprove.contracts and can be composed by a solver.
-- What’s included
-  - AGENTS.md: SWARM guidelines and MVP plan
-  - src/exprove: core primitives and engine
-  - tests/test_exprove_basic.py: basic unit tests
-  - test.sh: build and test harness
 
-This README should evolve as the MVP matures and more adapters and backtests are added.
+Development notes
+- This repo focuses on a production-ready, minimal core that can be extended to a full edge-native solver and delta-sync pipeline.
