sylph-decoder 8ebbfc70c1 re: the focus reader was two items out -- initial focus is NEW GAME, and my labels were wrong
menu_focus.py's row centres are design-space rows from screenshot output; my
probes fed it whole-display x11grab frames carrying Xenia's chrome and a surface
scaled 1.060. Caught by ground truth, not by a control: the probe announced 'on
EXTRAS', pressed A, and opened OPTIONS.

Measured directly with ring_row.py: initial focus on a fresh boot is NEW GAME,
2/2 fresh boots, both the first menu entry. That agrees with boot_menu.sh's own
line and menu-state-in-memory.md's four-downs, and withdraws this page's
'TUTORIAL 2/2' as the outlier.

Persistence stands and is now geometry-free -- 384.0 vs 385.5, 1.5 px apart. An
equality test is immune to a constant offset, which is why the conclusion survived
a broken reader when the published item names did not.

The control was structurally blind: 'two DOWNs move two items' tests relative
motion, and a constant offset preserves it exactly.

EXTRAS remains unmeasured; that run navigated to OPTIONS.
