unitscan probes for a watched rare by targeting its name, reading the name back,
and calling TargetLastTarget to put the old target back — but only
`if prevTarget ~= foundTarget` (unitscan.lua:112-130). Two things had to be true
inside that one Lua frame and neither was, so the restore never fired and every
scan kept your target. TargetLastTarget itself was fine and was never even
reached.
**The read after the call.** `TargetByName 0x489d60` runs the resolver and
selects before it returns, so the next line sees the pick. Ours queued a request
the app drained later in the frame, and the token snapshots had been pushed
*before* Lua ran — so the probing frame saw no change at all, and by the frame
that did see the mob, `prevTarget` had already been re-read as the mob.
The app now keeps each query a script has asked for resolved a frame ahead
(`by_name::feed_named_targets`, one candidate walk for the whole asked set, and
nothing walked at all when no script uses the verb). With the unit already in
hand the binding answers `"target"` for the rest of the Lua frame and queues the
selection *by GUID*, so the optimistic answer and the committed selection cannot
name different units. The override is dropped at the top of the next tick. A
query asked for the very first time keeps the old one-frame-late path, and that
ask is what starts it being resolved.
**The order of two selection verbs in one frame.** `TargetLastTarget`'s memory
was sampled once a frame, so mid-frame it still named whatever preceded the
*previous* selection: the restore would have landed on the wrong unit even with a
synchronous read. The reference stamps inside the selection itself, so its memory
is always the thing being left behind; `selection_requests` now calls
`LastTarget::note` per request, and the per-frame sampler stays as the catch-all
for selection changes that are not requests (a stream-out, a death clear, a
click-off). The two compose: the test walks the whole probe-and-restore sequence
and checks both the mid-frame pick and the memory the frame ends with.
Fixes the `/target X` then `UnitName("target")` macro idiom generally, not just
unitscan — SuperCleveRoidMacros is built on it.
