 ### C1. Innovation is necessary under naturally mixed apical traffic
 
+**Status: failed the frozen MNIST confirmation on 2026-07-22.** Three of four traffic
+realizations passed, but top-down projection seed 1234 produced a `+1.520`-point innovation gain
+over norm-matched raw feedback, below the predeclared `+2`-point threshold. The other top-down
+projection gained `+2.956` points and the two soma-traffic projections gained `+2.860` and
+`+3.180` points. All four passed the traffic-R2 and alignment requirements, and the no-traffic
+control had exactly zero mean change. The failed result is retained; it cannot be repaired by
+changing the MNIST threshold or excluding the projection. A new dataset may receive a separately
+frozen validation-only selection followed by an untouched test confirmation.

 The apical compartment must contain ordinary non-teaching traffic generated by the model or task,
 not only an additive nuisance chosen to match the predictor. Candidate traffic includes
 back-propagating somatic activity, top-down contextual state, and task-irrelevant feedback shared
