DeltaTrace MVP

A minimal, production-oriented scaffolding for end-to-end traceability in live-market
execution pipelines. This repository provides a core event-graph schema, a
deterministic replay engine, and governance scaffolding with starter adapters.

What you get
- Lightweight event graph primitives: LocalEvent, PlanDelta, OrderEvent, FillEvent, RiskCheck, AuditLog, PrivacyBudget
- Deterministic replay engine to reproduce a decision path from a delta stream and event log
- Governance ledger scaffold with crypto-signed audit entries (in-memory for MVP)
- Two starter adapters: FIX feed simulator and exchange gateway stub
- Packaging metadata and tests ensuring a safe MVP workflow

Usage outline
- Build and test: ./test.sh
- Explore the API under deltatrace.core and adapters package
- Extend with additional adapters and governance rules as needed

This README intentionally stays lightweight and actionable for quick onboarding.
