Distributed System Reference

Public Reference Implementation — No Proprietary IP

A local-first Python reference implementation of production-oriented distributed-system patterns, focused on boundaries and failure behavior rather than framework complexity.

Architecture

Request → Command Boundary → Idempotency → Queue → Worker → Persistence/Event

Demonstrated patterns

• explicit command identity
• asynchronous local queue boundary
• idempotency control
• retry and failure exhaustion
• dependency-light execution
• deterministic tests for failure paths

Scope

Synthetic/local behavior only. No proprietary production architecture, credentials, cloud resources, or private operational configuration is included. This repository is independent technical evidence.

Run

python -m pytest -q
