Semantic vectors

Evidenced values extracted from dossiers into comparable entries, one per investor, never shown publicly.

The semantic quantization pipeline only writes values it can evidence from the dossier. An investor's semantic entity waits in the state awaiting_dossier until dossier research is ready, then is processed; when the dossier changes it is queued again. The vectors are part of Deep Dive and are on the never-expose list.
