# F1 -- MEASURE THE MENU REPEAT RATE, as a count of presents between cursor moves.
#
# The human watched the real game: a held direction repeats. `C_PAD_DECODER` has
# no timer on any direction path (pad-decoder-double-tap-not-key-repeat.md), so
# the repeat is in the layer above and can only be MEASURED here.
#
# Instrument: the guest's own vertex stream via the UI draw logger -- the same
# instrument that settled the splash, and the one with no Canary processing in
# it. A cursor move shows up as the focused quad's NDC rect changing.
#
# ⚠️ Drives the boot BLIND on timings rather than classifying frames. That is
# deliberate: the classifier route costs a screenshot per poll, and screenshots
# cost ~10 s each while xenia runs. The draw log records what actually happened,
# so a mistimed press is visible in the result rather than silently assumed.
