trusty-mpm 1.7.3

//! CLI parsing for the bulk-read diversion pair (#6887).
//!
//! Why: split out of `tests_behavior_a.rs`, which sits 6 SLOC under the
//! 500-SLOC production cap — the same companion-file convention
//! `install_policy_tests.rs` and `tests_behavior_2903_skills_tests.rs` follow.
//! What: asserts `tm hook --divert-check` and `tm divert bulk-read` parse. The
//! launcher registers the first as a `PreToolUse` hook and the first's block
//! reason names the second, so a parse failure in either wires the feature to a
//! command that does not exist.
//! Test: this module IS the test suite.

/// reason names. Both must parse, or the feature is wired to commands that do
/// not exist.
