Fantasy Trade Analyzer for NHL, NFL & MLB

This is a Next.js project bootstrapped with create-next-app.

Engine verification (run before merging any engine or Draft Mode change)

npm run verify:nfl

Checks the NFL valuation engine (lib/nfl-valuation.ts) and the Draft Mode recommendation layer (lib/nfl-draft-rec.ts) against pinned calibration points on a frozen data snapshot — replacement bars, VAR windows, pick values, a reference trade rating, bench weighting, QB/K/DST suppression behavior, and rankings↔recommendation consistency. Exits nonzero on any FAIL. Expected ranges live in scripts/verify-nfl/fixtures.mts (one comment per scenario naming the regression it guards); re-snapshot/re-pin instructions are in scripts/verify-nfl/SNAPSHOT.md.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.
