As 'everyone' knows....there are several 'grades' of braced walls...

A, B, C, D, E...

A walls....2x4 for all studs....

B walls and higher...my drawings say this...

FRAMING AT FOUNDATION SILL PLATES AND ADJOINING PANEL EDGE STUDS SHALL BE A SINGLE 3xNOMINAL
MEMBER, AND ALL NAILS SHALL BE STAGGERED WITH 1/2" EDGE DISTANCE.

As we 'also' know....if the panel has a break (tall wall and the 4x8 sheet is not tall enough), the break has to be blocked.

So the question is (and I think I already know the answer)....when blocking between studs on B and higher braced walls, does the block have to be 3x lumber or larger?

I do not believe that a 3x block is a code requirement.
The 3x sill and 3x edge studs are not a requirement either but are a darn good idea.
I think your house was done as engineered shear walls though and not braced wall panels, so of course this should be asked of the engineer of record.

not many home owners as well as contractors are aware of the differences.
Braced wall panels are described in the CRC and are the "prescriptive" approach for anti racking, sliding and overturning.

Shear walls are designed by an engineer for the same.
