All three controls bracket the target but miss it at the selected gains. Without matched effects, this synthetic teacher-forced comparison cannot establish whether the gate is necessary.

Project E2: 16 calibration cases and five tested gains. Lines join measurements; large outlined points mark the selected candidates. None of the three arms met the prespecified effect match at a tested gain. Each curve brackets the target; the small diagrams isolate the measured endpoints of those brackets, not additional measurements or matched gains. The mini diagrams use separate logarithmic vertical ranges. This is a synthetic teacher-forced probe.
