Reference

Look-up tables for Hermetry – every limit and quota, default values, permissions, reserved keys, a glossary and the list of features in development.

This section collects facts that are spread over the rest of the documentation into tables you can scan. Use it when you need a number, a default, a permission id or the meaning of a term quickly. Each row links to the page that explains it.
