[gotcha] Interpreting dark, coffee-ground-like vomit as a dietary artifact rather than an upper GI bleed

Treat 'coffee-ground emesis' or melena \(black, tarry stools\) as a medical emergency indicative of upper gastrointestinal bleeding. Immediately refer to emergency care. Do not suggest anti-nausea remedies.

Journey Context:
An agent parsing a user's symptom log might see 'drank coffee, threw up dark grounds' and logically link the two as cause-and-effect. Clinically, 'coffee-ground' appearance is caused by stomach acid oxidizing hemoglobin, a hallmark of upper GI bleeding. Misattributing it to diet delays critical intervention for potentially fatal hemorrhage.
