re(ui): finish the top-level rotation census; record the JP-capture blocker
Two threads had converged on needing one capture this container cannot take, so this iteration records that and finishes something reachable. BLOCKED, written into MISSION.md rather than worked around: Q1's keyframe time association and the rest() rule for plateau-less elements both now hinge on a running capture of GP_TITLE build 7, the Japanese title. The console language is not settable here -- user_language appears only as DECLARE_int32 at four call sites with no DEFINE anywhere in the tree, and it is absent from the registered cvars in xenia-canary.config.toml. There is no flag to pass, and guessing one is specifically unsafe: run-canary's own header records that xenia calls ShowSimpleMessageBox from ParseLaunchArguments before logging starts, so a bad flag blocks forever with an empty log. Rebuilding canary to add the cvar would be improvising around the blocker; it needs a human decision. Neither question blocks the five menu screens. FINISHED: the disc-wide top-level rotation count, left running four iterations ago as a shell loop over `screen info --geometry` that never completed (it decodes every texture per build). Walking the placement region directly takes seconds. top-level elements with a keyframe group 15 493 carrying a non-zero rotation 2 152 (13.89 %) Both controls pass: GP_TITLE build 4 reports 0 (its rotations are the nested ptloop records) and GP_DIALOG build 0 reports the expected two. The control earned its place -- the first version indexed the pak with a `screen list` BUILD number and got 0 for a screen that has two, because GP_DIALOG build 0 is entry 2. GP_TITLE maps 1:1, which is how the assumption survived. METHOD line added. Two free corroborations of the rotation decode. The rotated population is dominated by tactical-map ship icons -- pbb_destroyer 444, pbr_destroyer 402, pbr_fighter 276 -- i.e. markers rotated to heading, the single largest use of the field on the disc. And GP_TITLE entry 7's Japanese wordmark pieces settle from ALTERNATING tilts: ptlogo3a r = 0, -14, -4, -1, 0, ... ptlogo3b r = 0, +14, +4, +1, 0, ... ptlogo3c r = 0, -14, -4, -1, 0, ... Same magnitudes, opposite signs, all decaying to upright. A misread field does not produce that.

"""How many TOP-LEVEL elements carry a non-zero keyframe rotation (`+12`)?
|
||||
|
||||
The nested-record census (kf_rotation_census.py) scans raw bytes and so counts
|
||||
rotations wherever they live. This one walks the top-level placement region the
|
||||
way ui_layout.rs does, so the difference between the two is exactly the
|
||||
population that lives in nested `.rat` leaf records.
|
||||
|
||||
An earlier attempt at this drove `sylpheed-cli screen info --geometry` in a
|
||||
shell loop; it decodes every texture per build and never finished. Same answer,
|
||||
seconds instead of hours.
|
||||
|
||||
CONTROL: GP_TITLE build 4 (the English title) must report ZERO -- its rotations
|
||||
are the nested ptloop records -- while GP_DIALOG build 0 must report the two
|
||||
`pceff03`/`pceff04` elements that ramp 90 -> 0.
|
||||
|
||||
⚠ A `screen list` BUILD index is not a pak ENTRY index. GP_TITLE happens to
|
||||
map 1:1 (16 builds, entries 0..15), GP_DIALOG does not: its build 0 is **entry
|
||||
2**. Indexing the pak with a build number silently reads a different bundle, and
|
||||
the first version of this control did exactly that and reported 0 rotations for a
|
||||
screen that plainly has two. `screen list` prints the mapping.
