0.2 Paul Sigma VALID Each Fantasy Rule must be proposed within one sentence.

I judge this FR to be VALID.

It is consistent with the RRs. Despite 'must be' sounding like an illicit attempt to act beyond the powers of FRs, I accepted 'must not' for FR0.1, so I must accept 'must be' here. 'Proposed' is a little odd: FRs aren't proposed; but I think it's clear that the meaning of this FR is that each FR consists of one sentence.

It is consistent with FR0.1, having initial letters b, e, f, m, o, p, r, s, and w once each.

It is consistent with itself, being of only one sentence.
