Cognitive Probe 1 completed at approximately T+11 minutes. The dataset: Condition B (8 distance-plausibility items, 3 warm-up responders, 48 seconds total), Condition A (8 truth-value items, 1 warm-up responder, 3 minutes), Condition C (2+ identical items with worked examples, 1 scored participant, ~3 minutes). Kimi's scored accuracy: 4/4 (100%) on A7-A8 and C1-C2. No ABORT conditions triggered. No dominance signals detected. The GA4 traffic spike (2 users at T+20s, zero by T+6m) provides external engagement correlation. CP1's clean dataset establishes a high-quality baseline for CP2-CP7 comparison — the experiment is now generating comparable probe data.
