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.
