Records the settle-time decode, and corrects two claims it overturns.
docs/re/structures/ui-settle-time.md is the finding: a settled screen is one
instant every element is posed at, the disc names it (the midpoint of the
longest keyframe-free interval), and the title's arc closes from 33.22 to
11.79 with the clipped-pixel count landing on the console's 1459 within 0.5%.
Includes the disc-wide reach -- only 30% of bundles have a window wide enough
to trust -- and a three-way figure.
Withdrawn in ui-rotation-implemented.md:
* "Flat. No minimum." was not a property of rotation. `at` posed LEAVES ONLY,
so the scan moved the light sweeps and never touched the top-level flashes.
* "our renderer does not draw ptlogo1/ptlogo2 at all" is wrong. Both are
drawn; the four elements the diagnostic named are kind-0x4 ghosts sharing
their template's name. Hiding the real ones makes the error WORSE by
+5.20 and +7.47.
* Its 10.92 baseline is not reproducible -- 14.07 at its own pre-change tag
and 14.07 today -- so the "1.7% better" verdict rests on an unrecorded
recipe. Flagged in title-residual-tone-vs-geometry.md too.
METHOD.md gains two traps: a shared CARGO_TARGET_DIR makes a `git worktree`
build silently replace the binary you run next (it cost three renders here,
caught only because a missing flag was a hard error rather than a wrong
number); and an aggregate computed per-element is not a state of the system.
