How to use

  1. Load the baseline ZIP.
  2. Apply the latest update: records are keyed by record_type and id, and an update record replaces the baseline record with the same key.
  3. Verify downloads against the SHA-256 values above or in manifest.json.

For agents

manifest.json lists the baseline and the current update with URLs, sizes, and hashes. current-update.json always names the latest update. See also /llms.txt.
