zeekayandHanzo Dev 2b594ab2c9 LoCoMo: every claim held to what the harness prints
A rerun of the measurement at hanzoai/semantic v0.2.4 found the result sound
and some of the prose around it not. Three statements were false. The subject
resolver matches any name the conversation uses and not only the two speakers,
so 11 questions fall back to searching everything, not 22. Deleting the derived
facts moves six more cells than the sentence admitted, and moves them both
ways: single-hop F1 up a thousandth, reach down two. And constant abstention at
0.228 is above every arm that has to retrieve, but not above the oracle's
0.252, which the paper's own Table 1 prints two pages later.

Two claims outran their evidence. "At every matched silence rate" generalized
from four wide-gap points past an 8% crossing where the gap is 0.002, and below
that rate the flat index cannot be matched at all; the sentence now says which
rates were measured and what happens at the quiet end. And the adversarial
questions carry no reference answer — the field the dataset gives them holds
the distractor, "yoga" for the worked example — so the paper no longer
describes a reference saying the conversation does not say.

"Scoped" named both a specific arm and a general property. Arms are now set in
typewriter and mean one thing each, subject scope is the factor, and the
abstract says which effect +0.152 is. Differences are taken from the unrounded
scores and rounded once, which §2.2 states and which moves the claim-span
effect to -0.029 and the interaction to +0.179.

Section 13 claimed seven commands produced every number, and at least six sets
came from nowhere in the repository. The harness now computes them: -stats
reads a predictions file back for the constant-abstention score, the AUCs and
the bootstrap intervals, and the run prints sessions, build totals and the
subject counts. The commands missing from the table are in it, and the four
figures that no command produces say where they come from.

The measurement, the tables and the conclusion are unchanged. Five interval
endpoints move by a thousandth, because the bootstrap is now enumerated over
all 92,378 resamples instead of sampling 10,000 of them.
