Live MTSS Grouping Dashboard

A zero-dependency demonstration of the GitHub-native lakehouse. Paste the progress files students export from any lesson (or load the sample), and this page computes a live gradebook, a per-standard mastery distribution, and dynamic flexible groups — entirely in your browser. Nothing is sent anywhere. The exact same engine (lakehouse-core.js) runs in CI for the persisted path.

Optional: load a class roster (real names + IEP/504/EL flags — PII)

Paste a roster { "students": [ { "code":"L-...", "firstName":"...", "lastName":"...", "iep":true, "el":true } ] }. Names stay in your browser — nothing is uploaded. Keep your real roster on the private side; this is only for live viewing.

No data yet — load the sample to see it work.
