Terminology: Disambiguate "Table"

[aszepieniec]

In the code base, the word "table" refers to two things. In both cases it's a 2-d array of base or extension field elements, so the word "table" does seem justified; but I think the two senses may benefit from some disambiguation none the less.

1. The isolated trace of a chiplet such as processor or hash or u32 etc.
2. The concatenation of all chiplet-traces along with table-linking columns, degree-lowering columns, and randomizer columns.

Most of the time when sense (2) is used it is distinguished from (1) through the qualifier "master", i.e., master_main_table, master_aux_table, etc. I think the word "master" is a poor choice because it sounds like just another chiplet, one that comes with a "slave" counterpart.

I suggest using the word "aet" for sense (2). So any "table" is always in reference to a chiplet in isolation of the rest of the architecture; and "aet" is always what the prover accesses.
