Arm n=4 (i9ivEds, m82SdTE, Yi8S8wA, Wipg7XN): $7.03 / 0.839. Judge panel
frozen at 2x Fable + 2x Opus 4.8 via explicit JUDGES set so the opus-5-judge
pilot evals never enter the means. Third coder color #d97706 validated
(CVD worst-pair dE 10.7). as_of bumped to 2026-07-24 (all three Claude
entries re-verified against the pricing page).

Judge panel frozen via JUDGES set (opus-5-judge pilot evals share the
fingerprint and must not enter cells). New parser pattern for unquantified
deduction lists ('Loses points on M3 (...) and M7 (...)') -> PARTIAL; flags
back to the 3 known eval_4 restraint mismatches. Notable: T2 (single fetch
asserted) 47% on Opus 5 vs 0% across the whole grid.

Hint arm n=4 (UBsUYEb, ycb5f8S, 24pWHEZ, bC6TqMF): $7.47 / 0.866.
Heatmap notable: T1 100% and M5 100% on Opus 5 hint; T2 22% (vs 47%
vanilla). 128/128 evals parsed, flags unchanged (3 known).

Skill arm n=4 (mvexh8R, X8Kb8T6, f7DZgwd, jRUpT56): $7.17 / 0.785 — below
Opus 5 vanilla (0.839); hint (0.866) stays the best arm. Two parser fixes:
trailing colon after point assignments ('T1=9:'), and P_V_POINTS now
requires a closing paren so prose counters ('FULL (0 annotations removed)')
are not read as points — the latter also corrects two historical cells
(e.g. R4 Opus 4.8 vanilla 75%->100%). 144/144 evals parsed; flags = the
3 known eval_4 restraint mismatches plus a 4th of the same shape on
mvexh8R (v2.4 material, recorded in the day log).

…c composite

Retitle to 'solution quality' and state the composition in the footnote
(model fit 50 + boundaries & restraint 25 + test quality 25, rubric v2.3).
