The subrelation witness degrees are used in zk-sumcheck and affect the sizes of the univariates in the SumcheckTupleOfTuplesOfUnivariates as well as the sizes of the sumcheck round univariates.

In several relations, I used upper bounds on the witness degrees which are simply given by the corresponding subrelation's length - 1. Indicated explicitly that those are upper bounds. Computed the precise constants for the relations relevant to Mega.

The auxiliary and logderiv_lookup_relation contain a trick allowing to re-use the values accumulated by an accumulator of a different size using ShortView.

Could you rephrase this comment so it's clear where it's being used? Also I think it's quite a confusing comment. Here and in the other places

please explain here the -1 and in the other places, it really helps the reader in a few months

Overall looks good, thanks for the additional docs, just some nit picks and requests for clarifying comments.

Resolved all isssues: added clearer definitions for SUBRELATION_WITNESS_DEGREES and explained the upper bounds appearing in some of the relations (mostly ECCVM and Translator). Added comments for the ShortView trick in logderivative and auxiliary relations.
