The two temporal noise allowances

For a uniform ordinary certificate one may count $N=2dT$ coordinates and use $R=1$, with coarse gate bounds. For a biased certificate one may count $N=(d+H)T$. External tanh again permits $R=1$. For biased ReLU use

Unused Gaussian coordinates can be included harmlessly in a conservative count. If no noise is present, no Gaussian exceptional event is needed.

These are sufficient survival bounds, not strict ordering theorems between two interventions.
