Observed evidence: source material, timestamps and provenance stay distinguishable from model-derived interpretation.
Model interpretation: severity, confidence, classification and story-correlation decisions carry their own versioned provenance.
Deterministic aggregation: once eligible inputs are fixed, the versioned v1.2 numerical aggregation does not use an LLM call or discretionary manual adjustment.
Validation limits: correlation is not causation. Predictive, audit, certification or institutional-validation claims are made only when the specific preserved evidence supports them.
