`verb_prof` wrapped every global and every widget method and charged each call
two `Instant::now`s — and the only caller of `log_report` was the
`addon_harness` **example**'s `--together` load. Armed in the client it paid
for every binding call and printed nothing at all. The one question it answers
— which binding a handler's self time went into — is exactly the open one:
`WOW_UI_HANDLERS` names `UIParent:OnUpdate` at 503 us/f in combat against 48
idle, and stops there.
So `WOW_UI_VERBS=<secs>` now prints a window from `report_window`, called at
the end of `UiScript::tick` beside the handler and raise reports, one level
down from them. The bare `=1` the harnesses already pass reads as one second,
which is why `period()` parses the same variable rather than taking a new one.
A window is a **delta** against a snapshot (`PREV`), not a `reset`: `ROWS` is
the one table and `log_report`'s callers read it whole at a moment of their
own choosing — `--together` ticks ten times before printing its load bill, so
a window that cleared the table would have handed it whatever happened after
the last window instead of the load. The arithmetic is `diff`, split out and
tested on its own because `window_delta` reads two process-wide statics and
`diff` is the whole of the logic.
It earns its keep immediately. `tick_bench` over the player's real 94-addon
folder, 121-frame windows: `frame:GetLeft` costs **0.42 us/call** on a settled
layout and **29.95 us/call** the moment anything moved — the same two calls a
frame, 55% of the frame's whole verb bill — because the four edge getters call
`settle()` and a resolve past tier 1 walks every live frame. During the load
burst the same call is **370 us**. `GetWidth`/`GetHeight` already carry an
authored-span shortcut for precisely this; the edge getters never got one.
