sylph-decoder f96f0cc985 re: the S00A drive failed -- initial menu focus was TUTORIAL, not NEW GAME
Reported as a route finding rather than retried silently, because the cause is a
defect in shared harness tooling that will bite the next drive.

Drive 1 sat 396 s reporting other with two spurious menu hits while the guest was
healthy and decoding audio throughout. screen_id.py thresholds on green and only
returns title once the PRESS A plate has faded in, so it cannot see the
plate-less build-4 title this corpus documents. It also calls difficulty-screen a
menu. Both reproduce on committed frames, and newgame_path.sh, nav_probe.sh and
boot_menu.sh all gate on it.

Drive 2, with a classifier controlled 6/6, reached title_plate at t=398 s and
drove on -- into a TUTORIAL MISSION. The screen 60 s after the last A correlates
+0.960 with the committed tutorial-mission-reached-then-crash.png, and no S00A
voice stream ever decoded. newgame_path.sh s header assumes NEW GAME is the first
item so no d-pad movement is needed; that contradicts this corpus s own Q5
result, where four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME.

Incidental corroboration: BGM_103 s two waves decoded on reaching the menu, an
independent runtime confirmation of the menu-music claim that HANDOFF rests on
static code and a disc census.

What is needed is a focus DETECTOR, and wrap-around means counting presses cannot
substitute -- up from the first item goes to the last. I do not have one: a
per-row brightness statistic failed its control, picking NEW GAME on the capture
whose filename says OPTIONS.

Also records a refutation attempt on the port s focus identification that FAILED.
Differencing the two captures and binning by row appeared to show NEW GAME and
EXTRAS changing, contradicting them. That was my error -- I placed row bands as
rest_y plus or minus 24, treating the resting position as a band centre. The
offset-independent check settles it: the changed bands are 254.9 design-y apart
against a button pitch of 80, so the two focused buttons are 3 apart and not 4 --
NEW GAME to OPTIONS. Their identification stands.
