resume_reliability.sh boots N times and records, per boot, whether the title's
loader thread was created and whether it ever became the CALLER of a kernel call.
That is the thing the threading fix targets, and it is binary; "did the menu
appear" is a worse test because it needs the game to get further and the attract
loop confuses it.
Two defects fixed on the way, both found by the harness disagreeing with itself:
* is_title.py's glyph count alone still fired at 113s and 173s, during the
intro movie, and the single press was wasted there. Measured, not guessed:
on those runs NO loader thread was created at all, and the title handler
always creates one - even on the boots where it then fails to run. The title
check now also requires the frame to be STATIC, reusing the RMSE between the
two grabs 0.6s apart that the movie branch already computes, and raises the
glyph threshold to 800 (a real title measures ~1450-1520, the SQUARE ENIX
logo 0).
* `grep -ac ... || echo 0` corrupted every CSV field it guarded: grep exits 1
on zero matches, so the fallback APPENDED a second value and the field came
out "0 0".
Retrospective before/after from the logs already on disc, using ResolvePath after
the resume (logged at every verbosity, so it is comparable across all runs):
before the fix 1 of 5 boots that created a loader thread went on to load assets;
after it, 2 of 2. n is small and a proper count is running.
