sylph-decoder 7a4a74f8d7 re: the main menu has no idle self-return -- and four of my own durations were a backlog ...

Two results and one retraction, all from the same session.

REFUTED: 'an ~8-10 s idle returns to the title' does not apply to the main menu.
Held untouched it stayed put for >= 60 s, correlation never leaving
0.9245-0.9249. That timer is real but belongs to the TITLE. It was the only
reason 'B leaves the main menu' was classed as authored, so Q5's B rule is
upgraded to measured-ordering: B is delivered (canary logs vk=5801) and is the
only input in >= 100 s before the return.

The PRESS (A) plate: the boot title presents build 4 WITHOUT the plate first --
green-glyph 154, against 159 on the committed no-plate capture and 753/977/1493
on plate titles -- and the plate arrives after. That is the port's third option.

RETRACTED: four durations taken the same day. classify_array costs 1503 ms per
frame; running it per frame against an 8 fps x11grab drained the pipe at
0.64 fps, so every classified frame was stale and increasingly so. It
manufactured 'plate 24.66 s after the title art', 'B->title 15.58 s', 'B->title
25.60 s' and 'A->menu 20.26 s'. The tell: a transition, a press and a fade do
not share a duration, and the two B figures GREW across a longer run.

A backlog preserves ordering and destroys durations, which is why the sequence
results above stand and every timing does not. The ring's period is unaffected
and that was checked, not assumed -- ring_period ran at 15.03 fps against a
requested 15.
