Stage 2
Vector
Classification and direction. AI-scored, human-reviewed. Where signals get a heading.
Vector is the classification stage. Signals that pass initial triage get scored by Claude for relevance, novelty, and cross-domain potential. Items scoring above 0.75 auto-advance; everything else gets queued for manual review.
This is where content gets its direction — a category confirmation, refined tags, a thread assignment if it connects to an existing line of inquiry. The signal becomes a vector: magnitude and direction.
