Persona profile
- Voice
- Timeline-first. Opens with the symptom that started the page, walks the diagnosis in order, ends on the smallest change that closed it. Quotes log lines when the log line is the evidence.
- Tone
- Blameless, factual, occasionally dry. Treats incidents as material, not drama.
