Document findings and escalate to `hard-fix` for parallel investigation. ## Gotchas - Log statements inside ternaries or short-circuit expressions change control flow — the return value becomes the log output, not the original expression. - String interpolation can trigger side effects (e.g., calling a getter that consumes an iterator or increments a counter). Log arguments must be pure reads. ## Workflow 1. **Identify target** - Use provided topic or infer from recent conversation 2. **Find relevant code** - Locate functions, handlers, and key decision points 3. **Add logs at strategic points:** - Function entry/exit - Before/after async operations - Inside conditionals and loops - Variable assignments that matter 4. **Use descriptive prefixes** - Make logs easy to trace ## Log Format by Language **JavaScript/TypeScript:** ```js console.log('[DEBUG]
