Equal leg angles are scaled up by a factor of 1.56 for deflection provided you are using the Ixx
They should be designed for the full height of brick above. Deflection will govern L/480 (see s304.1 masonry code Canada). Even if you have a control joint on one side only arching is ineffective...
I think the single dashed line in the loft space represents where the ceiling goes from sloped to flat. The architect did not fully clarify this but I think a lot of the ceiling is flat.
