Refuted my own evidence with a direct test. The A-press fault page cited the faulting run's dumped logged_profile_slot_0_xuid = "" as proof no profile was signed in. Xenia prints its config dump BEFORE applying command-line overrides: in a run launched with --apu=sdl --hid=file --mute=true --log_mask=13, the dump says apu="any", hid="any", mute=false, log_mask=0. Four for four. So the dump is a statement about xenia-canary.config.toml and nothing else, and this page cannot know the faulting run's profile state. Anything in the corpus citing a config dump as evidence of what a run did is making the same mistake; to know a run's settings, record its argv. Survives: the mechanism (swallow -> unbounded pump -> failed allocation -> fault), which rests on the [RE-INPUT] counter and the crash dump's registers; and canary-scripted-input-traps.md section 3's measured sign-in-dialog claim, which has a capture behind it. Also records the port's base-plus-glow mechanism for the plate, which explains why the pulse floor is 714 rather than the plate-absent 159 -- ptbtn00's fade at t=244 is an exit ramp so the base holds at 255 while the screen is held, and ptbtn00f's 0->80->0 glow draws over it. Marked as agreeing with the measurement, not confirming it: their renderer is not an oracle. It does rule out a glow-only plate, which could not produce a non-zero floor.

"""Wait for the interactive title, press Ⓐ once, and watch what happens.
|
||
|
||
The A/B this exists for: does a signed-in profile prevent the Ⓐ fault
|
||
(`docs/re/structures/title-a-press-fault.md`)? A press sent before the title is
|
||
up tests nothing, so the wait is a **control on the press**, not a convenience —
|
||
`is_title.py`'s glyph counter has to clear its threshold first.
|
||
|
||
wait_and_press.py OUTDIR [wait_s] [watch_s]
|
||
|
||
🔴 The first version of this used a SINGLE frame over a glyph threshold, and it
|
||
fired on the intro MOVIE — twice, voiding both legs of an A/B. The movie throws
|
||
green flashes of 1298…5433 lasting under a second, which clears any threshold the
|
||
title also clears. This is the same trap `is_title.py` records `screen_id.py`
|
||
falling into (the SQUARE ENIX logo called "title" 151 s in).
|
||
|
||
The title is distinguished by the **plate's pulse**, not by brightness: a
|
||
sustained oscillation that never drops below ~700 and never exceeds ~1600
|
||
(`docs/re/structures/plate-pulse-measured.md` measured 714…1520). So the detector
|
||
requires HOLD consecutive samples inside a band. A movie flash is 2–4 samples and
|
||
overshoots the top of it.
