Claims

The two targeted ablations produce small, partially counter-directional effects: removing the construct map does not materially change the composite score (p = 0.34 on equivalence)

Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Removing the construct map from chain-of-thought raises the joint score from 0.876 to 0.877 while construct equivalence drops from 0.960 to 0.950, a shift that does not approach significance (p = 0.34); the few-shot wording contrast moves equivalence by two points with an essentially unchanged joint score. → Ernesto Lee 2026

q2 · i? · causal · r1

Descriptive contrasts from the single experimental trial, reported in the Results ablation subsection and confirmed as nulls by exact paired tests (construct-map equivalence shift p = 0.34; few-shot wording contrast p = 0.375 on equivalence, p = 0.87 on joint score).

"Removing the construct map from chain-of-thought raises the joint score by a sliver ( 0.876 → 0.877 ) — the construct map step does not, in our pilot, materially improve the composite, and a modest drop in construct equivalence ( 0.960 → 0.950 ) is offset by tighter readability dispersion."
