 "what": "[TBC: 2] Appendix C.3's three-yardstick ablation comparison, in nats over the random sets' mean rather than in control standard deviations",
 "why": "the control's spread is long-tailed at 83.9 B and 2,034 B -- about twice its own mean and still rising with the mask count -- so a control standard deviation has no converged denominator there. Nats over the random mean need no spread.",
 "definition": {
  "rise_over_random_mean": "the loss with the yardstick's carrier set zeroed, minus the mean loss over the size-matched random masks, in nats, at the construct's own positions. Signed.",

C.3's pre-registered test is this paired median for code-coordinate minus one cell; the difference of the two medians is a different number and is reported beside it so they cannot be confused.",
  "sign_test": "count above zero over the 16 constructs; one-sided for a yardstick's own effect, two-sided for a paired difference, which has no prior direction",
  "interval": "construct bootstrap, 10000 resamples, 95% percentile, seed 20261024",
