trusty-mpm 1.8.2

//! Tests for [`super`] — `tm doctor --fix-skills`.
//!
//! Why: the three owner constraints on a fix mode (never silently overwrite a
//! frozen skill, always back up, always verify from disk) are safety rules, so
//! each gets a test that fails if the rule is removed. The deletion boundary is
//! asserted too: nothing this module touches may disappear.
//! What: one test per constraint plus the ordinary repair path.
//! Test: this file.
