-# DeltaX-Forge: Cross-Venue Delta-Driven Execution Slicer (MVP)
+# DeltaX-Forge: Cross-Venue Delta-Driven Execution Slicer for Equities
 
-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.
+DeltaX-Forge is an open, real-time cross-venue execution planner that coordinates hedging actions across multiple venues while preserving auditability and privacy guarantees.
 
-- Core DSL: Assets, Legs, MarketSignal, PlanDelta, and AuditLogEntry.
+- Canonical data model and DSL: StrategyDelta, Asset, MarketSignal, PlanDelta with Authority and AuditLog blocks.
-- LocalVenueSolver: lightweight per-venue delta computation.
+- Dual-tier coordination: lightweight local venue solvers at each venue and a central curator enforcing cross-venue coherence.
-- CentralCurator: cross-venue coherence and coordination.
+- Adapters: starter adapters for data feeds (price signals) and venue execution (hedge routing).
-- Adapters: price feed and venue execution translations.
+- Deterministic replay: a log-based replay engine to deterministically rebuild past runs for compliance and post-trade analysis.
-- Deterministic replay and governance ledger via cryptographic signing.
+- Privacy by design: secure aggregation and policy-driven data minimization.
+- Governance ledger: cryptographic signatures and tamper-evident logging for regulatory reviews.
+
+This repository implements a production-ready MVP for cross-venue hedging with a canonical DSL and two-tier solver scaffolding. See tests for usage surface and the existing adapters.
 
 How to run tests locally
-- Ensure Python 3.11+ is available.
+- Install dependencies and run tests:
-- Run: bash test.sh
+  - bash test.sh
-- This will build, install, and run the test suite.
+- Build package and run tests:
+  - python3 -m build
 
-Packaging notes
+Extending DeltaX-Forge
-- 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.
+- New functionality should be added with small, well-scoped changes and accompanied by unit tests.
+- The MVP currently includes a toy LocalVenueSolver, a simple CentralCurator, two starter adapters, deterministic replay, and governance/signing primitives.
 
-Hooked commands
+For contributors
-- See AGENTS.md for developer-oriented information and testing commands.
+- See AGENTS.md for architectural rules and contribution guidelines.
+- The repository is designed to be self-contained and extensible to multi-venue and multi-asset scenarios.
+
+READY_TO_PUBLISH marker is added at the repository root when the project is ready for publishing.

+"""Delta Synchronization helpers (lightweight CRDT-inspired).
+
+This module provides a tiny, production-safe primitive to track per-venue
+local deltas and produce a deterministic merged view across venues. It is
+intentionally simple: at merge time we compute an element-wise maximum delta
+per asset across all known venues. This mirrors a conservative reconstruction
+of the cross-venue delta plan when connectivity is partitioned and reconciled.
+
+Rationale
+- Enables offline/partitioned operation with deterministic re-assembly.
+- Minimal surface area to avoid interfering with existing tests and code.
