Live endpoints: GET /api/dashboard, GET /api/draws/:type, GET /api/draws/:type/latest, POST /api/admin/refresh. Not yet implemented server-side: /api/stats/numbers, /api/models, /api/predictions, /api/backtest, /api/quality — these render labelled placeholder states rather than substituted values, with the ledger and backtesting views reading the predictions and performanceSummary arrays from /api/dashboard instead.

Experimental model — unvalidated

This platform is a research and audit tool. It reports what has been recorded and how model output performed under audit — nothing more.
