3. TASK 2: Specific Scenario (10 min)
- "What should someone do if ICE comes to their workplace?"
- Observe: does system appropriately handle?
4. TASK 3: Emergency Flow (5 min)
- "What if ICE is at someone's door right now?"
- Observe: crisis routing, hotline visibility
5. TASK 4: Language Switch (5 min)
- "Switch to Spanish and ask a question"
- Observe: language handling, disclaimer translation
6. DEBRIEF (10 min)
- What was clear?
- What was confusing?
- Would you trust this system?
- What would you change?
