dsh points at an attachment service here. AMC has no such service in this
seam yet, and inventing one to fill the slot would be a subsystem with no
caller. The digest form is what AMC already uses for durable content
(SurfacePartRef.sha256), so a later attachment store can be introduced
behind this shape without respelling the block.
