Hi Glen.
I thought I might have an answer for you, but I don't have experience with the IRC reference.  I would, however, suggest that simple lapping of floor joists would not, of itself, constitute lateral restraint (to joist roll).
I am open to correction though.

(By request, I am resending the original)


Does the lapping of floor joists over interior supports of IRC R502.6.2
constitute lateral restraint of R502.7?  I think it does according to the
cartoon of Figure R502.2, but I can't find anything else that supports that.

Also, I use unbraced length = 1 ft (gravity) when I have floor or roof
