System Documentation

What problem does it solve?

Deep root-cause analysis of concurrency, race condition, and duplicate processing bugs in large webhook-backed systems. It focuses on read-only investigation to identify where timing leads to duplicates or inconsistent processing, without changing any code.

Core Features & Use Cases

  • Read-only diagnostic framework to trace trigger → handler → idempotency check → mutation → side effects.
  • Phase-based approach for Shopify webhooks, background sync workers, and cron jobs to locate TOCTOU races and additive mutations.
  • Real-world scenarios include webhook double-firing, "processed twice" events, intermittent data corruption, and race-condition symptoms.

Quick Start

Follow a phase-based investigation to identify concurrency windows and idempotency gaps in your systems.
