What is this Python project?

Reflexio is a small, explicit retry library designed for real-world distributed systems.
It focuses on classifying failures into coarse error classes (TRANSIENT, RATE_LIMIT,
CONCURRENCY, PERMANENT, etc.) and applying different retry strategies per class. It
provides sync and async support, a simple @retry decorator, and structured retry
events for integration with logging and metrics.

What's the difference between this Python project and similar ones?

Existing retry libraries such as Tenacity and backoff generally apply a single
backoff model and treat all exceptions uniformly. Reflexio takes a different
approach:

• Errors are classified into error classes before retry decisions are made.
• Each error class can have its own strategy (decorrelated jitter, equal jitter,
  fixed delay, fail-fast, or no retry).
• It emits structured retry events for observability (attempt number, event type,
  sleep duration, error class, strategy).
• The API surface is intentionally small and explicit, making retry behavior easier
  to reason about.
