Error Handling Guide

Philosophy

Errors are data, not surprises. A well-designed system anticipates failures and handles them gracefully.

Core Principles

1. Fail fast - Detect errors early, before they propagate
2. Fail loud - Log errors with enough context to debug
3. Fail gracefully - Provide useful feedback to users
4. Fail safely - Never expose sensitive information

"The only truly reliable systems are those designed to fail gracefully."
