Classify evidence as load-bearing or attributive, draft the emission-cadence declaration for Taxonomy, treat silence as a stream finding, keep completeness separate from record richness, forbid immune memory as a state plane, and make containment proposals reconstructable to their origin. Observe real qonto-assistant audit events; deny-class completeness stays unknown until the source publishes a heartbeat. Assistant: grok Assistant-Session: 01a05ef1-9e5a-70f2-b0ff-0b05d6b38ae9
