§ 01  Everything it does

Thirty-six tools, and one deliberate absence.

Every one of them is in the window and in the command line. None is behind a paywall, a sign-up or a page count, because there is nothing to upgrade to. Redaction is deliberately not here, and the dashed slot below says so rather than hoping you do not count.
