`ui_draw_capture.sh` boots to the title screen and arms Canary's new `log_ui_draws` there — deliberately WITHOUT tapping A on the title, which is the subject and which sends the guest into a save-data probe. ARM=early presses F10 before the title exists, for the frames in which a screen is built. A grab that is not full-width is a hard error rather than something to classify. `ui_draw_order.py` turns the capture into a named paint order: the UI shader emits NDC, so a quad's pixel rect is exact, and the disc's sprites have near-unique decoded sizes, so the rect's SIZE names the sprite. Matching is nearest-within-6px with the distance printed, because a quad comes back a few pixels under its sprite for a reason that is not yet measured.

# ONE blocking session: boot -> title screen -> arm the UI draw-order capture.
|
|
#
|
|
# Unlike skip_intro.sh this deliberately does NOT tap A on the title: the title
|
|
# screen IS the subject, and a stray A there sends the guest into the save-data
|
|
# probe (which crashed the guest on run 1 of 2026-08-18). It taps A only while a
|
|
# movie is playing, and the instant the title is classified it presses F10,
|
|
# which arms `log_ui_draws`' 3-frame submission-order dump.
|
|
#
|
|
# The log lands in the emulator's CWD, so the emulator is launched from $OUT.
|
|
#
|
|
# A grab that is not full-width is treated as a HARD ERROR rather than
|
|
# classified. Run 1 spent 13 minutes acting on a 10-pixel sliver: the screenshot
|
|
# wrapper had picked a 10x10 helper window that shares the class "xenia_canary"
|
|
# with the real one. Nothing failed loudly; the classifier just returned noise.

# Usage: ui_draw_capture.sh [timeout_s] [out_dir]
