[gotcha] Triaging a sudden, severe 'thunderclap' headache as a standard migraine or tension headache

Any headache reaching maximum intensity within 1 minute must be triaged as a medical emergency \(potential subarachnoid hemorrhage\) requiring immediate ER referral, not home remedies.

Journey Context:
Agents see 'headache' and default to common, benign causes \(tension, migraine\). However, the onset speed is the critical red flag, not just the severity. A headache that peaks in seconds to a minute is a vascular rupture until proven otherwise. Treating it as a normal headache delays life-saving intervention.
