The task

Reconciling a four-laptop meeting recording Last Wednesday's cross-team delivery sync (room 4B, ~40 minutes) was recorded four times at once: each of the four participants ran the meeting recorder on their own laptop, through their own USB headset microphone. Nobody started at the same instant, and none of the four laptops' audio sample clocks actually runs at its nominal rate — consumer ADC crystals sit at tens of …

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Difficulty, with uncertainty

Selected-best difficulty: 100.0% [72.2%, 100.0%]. This is one minus the best measured current-row pass rate among rows with at least five valid runs.

The maximum is selected from the observed rows, so the estimate is optimistic. Its Wilson interval is not adjusted for model selection. “Hard” requires qualifying GOOD_FAILURE evidence; the threshold flag additionally requires the interval and recorded quality gates to meet the documented rule. This is not independent validation. Threshold flag: yes.

Every recorded run

14 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
