Gemini 3.1 Pro round-15 full-paper review of v3.14 returned Accept
with four MINOR polish suggestions. All four applied in this commit.
1. Table XIII column header: "mean cosine" renamed to
"mean best-match cosine" to match the underlying metric (per-
signature best-match over the full same-CPA pool) and prevent
readers from inferring a simpler per-year statistic.
2. Methodology III-L (L284): added a forward-pointer in the first
threshold-convention note to Section IV-G.3, explicitly confirming
that replacing the 0.95 round-number heuristic with the nearby
accountant-level 2D-GMM marginal crossing 0.945 alters aggregate
firm-level capture rates by at most ~1.2 percentage points. This
pre-empts a reader who might worry about the methodological
tension between the heuristic and the mixture-derived convergence
band.
3. Results IV-I document-level aggregation (L383): "Document-level
rates therefore bound the share..." rewritten as "represent the
share..." Gemini correctly noted that worst-case aggregation
directly assigns (subject to classifier error), so "bound"
spuriously implies an inequality not actually present.
4. Results IV-G.4 Sanity Sample (L273): "inter-rater agreement with
the classifier" rewritten as "full human--classifier agreement
(30/30)". Inter-rater conventionally refers to human-vs-human
agreement; human-vs-classifier is the correct term here.
No substantive changes; no tables recomputed.
Gemini round-15 verdict was Accept with these four items framed
as nice-to-have rather than blockers; applying them brings v3.15
to a fully polished state before manual DOCX packaging.
