//! The shipped **inspect window** driven end-to-end, engine-only (no Bevy): the real
//! The reference's own `Blizzard_InspectUI` addon loaded behind
//! `Fonts.xml`/`UIParent.xml`/`GameTooltip.xml` and fed a synthetic target snapshot + a foreign
//! equipment view (decision 0631). `character_tests.rs`'s harness, turned onto the other paper doll.
//!
//! What these are here to falsify, in order of how quietly it could have shipped broken:
//!
//! 1. **The range gate really gates.** `InspectUnit` out of range must not open the window. A
//!    `CanInspect` that always answered truthy would look perfectly fine in play — you would just
//!    be able to inspect across the zone — so the boundary is asserted at the verified thresholds,
//!    including the strict-vs-non-strict asymmetry between the two predicates.
//! 2. **The slots come from the inspected unit, not from us.** The whole slice is one router change
//!    (`Model::inv_slot`); if it fell back to the self feed, the window would show *your* gear on
//!    someone else's doll — plausible-looking and completely wrong. So the two sources are fed
//!    deliberately different items and the doll is checked against the foreign one.
//! 3. **The window's own lifecycle.** Open/close sounds, the level line off the target snapshot, the
//!    `UNIT_INVENTORY_CHANGED` repaint, the rotate buttons moving the booth yaw, and
//!    `ClearInspectPlayer` firing on hide (without which the app would keep resolving a closed
//!    window's target forever).

/// argument at `0x519fb4` with `lua_isstring` and raises `Usage: SetPortraitTexture(texture,

/// shipped code. The widget clear sits six instructions PAST the gate, so the portrait is not even
/// blanked; it is left exactly as it was.
///
/// In the reference the raise unwinds to the handler's `lua_pcall`, abandons the rest of `OnShow`,
/// and pops the ScriptErrors dialog through `_ERRORMESSAGE`. Ours collects it into `errors` and
/// abandons the handler the same way. So: the window shows, the portrait and name do not update,
/// and there is exactly one error — which is what this now asserts.

/// One correction from that census worth keeping: stock 1.12 ships **no** inspect keybind (0 of 234
/// `Binding name=` entries) and no caller of `ToggleInspect` outside the addon's own tab buttons,
/// which are children of the hidden `InspectFrame`. So on the stock UI's own paths this is
/// unreachable — only an addon or a macro gets here. It is still ours to reproduce.
