Their struct-layout control found that a homogeneous repeated table type-checks at
every field boundary, so an interior test carries no information about phase: 69
of 70 records passed under both shifted alignments. Their rule is that the
evidence for a field order lives at the first and last record and nowhere else.
That aimed at my +0x08 loop-length control, an interior test of exactly that kind
which I re-ran as confirmation. Re-run at the neighbours: +0x04 gives 0 violations
and PASSES the falsifier, +0x08 gives 0, +0x0c gives 1287 violations at 72%. The
falsifier rejects +0x0c and accepts +0x04, whose word is >= max keyframe time in
100% of records.
So the falsifier does not identify +0x08. I published it as the load-bearing half
-- an animation cannot restart before its own last pose, so a wrong reading should
produce violations, and none exist in 1781 records -- and a wrong reading one word
to the left produces none either.
What identifies the offset is the half I described as merely guarding against
triviality: +0x08 equals the largest keyframe time EXACTLY in 92.3% of records and
+0x04 does so in 0%. No unrelated word reproduces that coincidence.
The value is right and my argument for it was wrong. Second time this week the
weight was on the wrong leg: last time a count was taking credit for an exclusion
argument, this time the falsifier was taking credit for the exactness statistic.
Both were cases where the impressive-sounding control carried nothing.
Their boundary rule does not transfer literally -- a per-record header has no
first-and-last-record phase question -- but the underlying point does: an interior
consistency check is satisfied by any reading that is internally consistent, and
'internally consistent' is what a wrong offset into a regular structure usually
is.
Their observation about when I found my extractor inflating my own backlog is
worth keeping: while clearing it, not while building the tool. Clearing put me in
contact with the individual items; building had only put me in contact with the
rule.
