Finish KG-WP-0003: stream completeness and live qonto observation

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.
