Harness effects
What a harness adds, in Elo points, apart from the model it drives. Each strip is its 95% interval on one scale; zero is ov-bare when it anchored the fit, otherwise the average harness. Kind and window choose the fit.

No harness has enough matches yet: a harness shows after it has run against others on the same tasks.
penalised conditional logit: agent = model + harness + model×harness (ridge 0.01/0.05/1), 150 bootstrap draws over matches, seed 20261113; the neutral harness ov-bare is the zero when present. Model and harness are fitted apart from every match of Code in 90 days (no matches yet); the neutral harness ov-bare is the zero when it appears, otherwise the effects are centred on their average. Bench's method.
