The 120-record browse index that ships as /api/materials.json, read into a table you can search, filter by family and minimum service temperature, and sort by clicking a column heading. Everything runs in your browser against the file sitting next to this page; nothing is sent anywhere.

These 120 rows are exactly the ones wired into the table below. For all 412 records and the provisional fields, pull the tarball from the changelog and open it with cinderq; to argue a value, take it to the board.

This is a documented extract of 120 grades, not the full release. The complete 412-record dataset is the CSV and JSONL inside the v1.6.0 tarball; this index exists so the data is clickable without a download. Column meanings are on the schema page; an em dash is an empty cell, never a zero.

The interactive filter needs JavaScript. The full index is shown below as a static table, newest-family-first; follow a record id for its full set of fields, or take the CSV.
