📋 Decision Context

Question:

How should we handle async operations that might hang indefinitely in Chrome extensions?

Task: Session 82.5 - Environment-Aware URLs: Timeout pattern for async operations

🎯 Decision Made

Chosen:

Promise.race() with 3-5 second timeout

Options Considered:

1. No timeout - rely on browser/extension timeouts
2. Fixed timeout (e.g., 5 seconds)
3. Promise.race() with configurable timeout
4. Retry with exponential backoff

💭 Reasoning

Chrome extension popup was stuck on 'Syncing...' when service worker didn't respond. Promise.race() provides clean cancellation and user feedback within reasonable time (3-5 seconds). Prevents UI from hanging indefinitely. Timeout can be adjusted based on operation type. Clean pattern that works with async/await.
