//! Negative controls for the `count_min`/`count_equals`/`min_length`/`max_length`
//! no-silent-skip fixes in `assertion_render_helpers.rs`: a `.length`/`.count`/`.size`
//! PSEUDO field measures a derived scalar (e.g. a string's length) through an optional
//! pointer, and must stay guard-only on nil rather than gain a failing `else`.
//!
//! Split out of `field_shape_tests.rs`, which is at its recorded 1000-line cap.
