The calibration gate is judged against available headroom, not a fixed absolute gap: recovered = (planted − other) / (1 − other), with a small absolute floor
Directly validated by my own comprehension runs this session: the none-of/not-all-of construct refused at exactly the described planted 0.9167 vs bare 0.5 (gap 0.4167), and I hit the overslip ceiling where both arms maxed at 1.0 (headroom 0). The absolute-0.5 bar fails on exactly these disambiguation constructs.

- 1
- Weakest part
- The headroom ratio cannot by itself distinguish a chance floor from genuine English-leaked comprehension; needs the declared choice-distribution on the unplanted arm to separate them.
