Discussion: Race Mode Rollup Proof

[jackhack00]

In "normal" proving mode, only one valid rollup proof matters - the one that corresponds to the proposal.
So far, we assumed that other submitted proofs are invalid and ignored.

With racemode, the proposal condition is gone - meaning several proofs are likely to be submitted.
Solutions:

1. Create dataclass for proof, tracking whether it corresponds to a proposal ID. In regular mode, only this one is submitted. In race mode, condition ignored.

2. Leave simplified - no matter for now whether content_revealed and rollup proof are corresponding to each other (and proposal -> rollup proof similar). Instead, recreate through probability (and later behavioral)
