Diagnosis is a human-made systematic process for identifying problems, conditions, or underlying causes through structured evidence analysis. Parameters: (1) evidence gathering — observation, testing, data collection; (2) pattern matching against known frameworks (symptom-checklists, diagnostic criteria, fault trees); (3) conclusion — identification of the specific problem or cause. Persistence mechanism: standardized diagnostic manuals (ICD, DSM, SNOMED), medical/scientific education, clinical practice protocols.

Diagnosis operates by applying domain knowledge to identify patterns in observations. Remove knowledge and diagnosis ceases to operate — without domain knowledge, there is no basis for pattern recognition, differential diagnosis, or clinical judgment. Passes Law 8 removal test: diagnosis needs knowledge to function at the object level.

The concept of latent conditions arose from the practice of diagnosis — diagnosis existed first and fed into the notion of conditions that exist but are not yet apparent. Which came first? Diagnosis as a practice predates the abstract concept of latent conditions.
