DeltaTrace MVP: Deterministic Replayable Latency & Compliance Tracing
|
||
|
||
Overview
|
||
- DeltaTrace provides a tiny but practical MVP foundation for end-to-end traceability in live-market pipelines.
|
||
- Focus areas: deterministic replay, cross-layer event graphs, auditability, and lightweight adapters that avoid vendor lock-in.
|
||
- The current repository contains a minimal core, a deterministic replay engine, and a trace payload model that can be extended into a production-ready toolkit.
|
||
|
||
What’s inside (core MVP)
|
||
- deltatrace.core: lightweight event graph primitives (LocalEvent, PlanDelta, OrderEvent, FillEvent, RiskCheck, AuditLog, PrivacyBudget, MessageMeta) and a minimal in-memory TraceGraph.
|
||
- deltatrace.replay: DeterministicReplayEngine that consumes a delta-stream and yields a deterministic ordering of events.
|
||
- deltatrace.trace: a small but usable form for trace payloads (LocalEvent, PlanDelta, etc.) with JSON-serializable to_dict and from_dict helpers.
|
||
- adapters/: starter adapters (FIX feed simulator, exchange gateway) to illustrate plug-and-play deployment.
|
||
- governance/: scaffolding for governance logs and audit trails.
|
||
|
||
How to run
|
||
- Ensure you have Python 3.9+.
|
||
- Install (local development): python3 -m build && pip install -e .
|
||
- Run tests: ./test.sh
|
||
- You can also import modules in an interactive session to experiment:
|
||
from deltatrace.core import LocalEvent, PlanDelta, ReplayEngine
|
||
from deltatrace.replay import DeterministicReplayEngine
|
||
|
||
Usage patterns (MVP approach)
|
||
- Build an event graph across layers: LocalEvent -> PlanDelta -> OrderEvent/FillEvent -> RiskCheck -> AuditLog.
|
||
- Capture a delta-stream and an event-log, then use the deterministic replay to reproduce a specific decision path.
|
||
- Use the governance scaffolds to crypto-sign and tamper-evident-log entries for auditability.
|
||
|
||
Roadmap (high level)
|
||
- Phase 0: Core schema, deterministic replay, 2 starters adapters (FIX feed, exchange gateway).
|
||
- Phase 1: Privacy controls and governance ledger scaffold.
|
||
- Phase 2: Partitioned-network testbed with sandboxed exchange.
|
||
- Phase 3: Incident replay dashboard and governance reporting.
|
||
|
||
Contributing
|
||
- Small, well-scoped changes with tests.
|
||
- Follow the existing style and add docstrings.
|
||
- Run test.sh after meaningful changes.
|
||
|
||
This repository is designed as a production-oriented MVP: small, well-typed, and easy to extend. For questions or collaboration, ping in the repository issues and PRs.
