 # Feature 1.3 — Prop Analysis Engine
 
 ## Overview
-The core intelligence of BetonBLK. Takes a player prop (player, stat, line, book) and runs a 6-step grading pipeline to produce a grade (A/B/C/D), edge percentage, confidence score, kill condition flags, and natural-language reasoning. This is the engine that powers the parlay scanner (Feature 2.1) and drives all user-facing analysis.

 # Feature 2.1 — Parlay Scan
 
 ## Overview
-The flagship user-facing feature. A user submits a parlay (array of prop legs), BetonBLK grades each leg individually, checks for correlations and conflicts between legs, produces an overall parlay grade, and writes the scan to the database. Free users get 5 scans per month. At scan 5, the system fires a personalized upgrade pitch based on what it learned from scans 1-4.
