I set the value to 0 with an explicit condition: revisit at the next measurement
that is not 0, or the moment a rule appears. Five measurements now exist -- 0, 4,
6, 6 from the Decoder and ~7.9 from my own verify-dwell shortfall, which arrived
by a different route when the tool stopped absorbing it into slack. Four of five
non-zero, mean 6.0.
Attempted a rule so that any change would be principled rather than fitted: does
the incoming screen's opening black-clear absorb part of a fixed black period? Sums
are 16, 16, 18 on the three menu/title transitions -- suggestive given +/-1 frame --
and 7.9 on the splash pair, whose backdrop is a single keyframe at alpha 255 and
never clears. Three points fitting a constant with one outlier is a fit with an
exception, not a rule. Not adopted.
So my justification for 0 has failed on its own terms -- it now omits a real
quantity on most transitions, which the tripwire called a different invention --
and the alternative is a fit chosen for its residual. Both invent, so this goes to
BLOCKED.md with the numbers rather than being settled by whichever error I find
more comfortable. Value stays 0 pending that, with verify-dwell reporting the
shortfall.
