Log-Driven Debugging

Core Principle

Never assume the cause. Verify with logs.

Debugging Workflow

1. Gather Information

   • Ask: "What is the exact symptom?"
   • Ask: "When does it occur?"
   • Ask: "What is the expected behavior?"

2. Form Hypotheses

   • List 2-3 probable causes ranked by likelihood
   • Consider: API issues, state mutations, async timing, type errors
