+Subject: [PATCH 2/5] rts: Statically assert alignment of Capability
+
+In #22965 we noticed that changes in the size of `Capability` can result
+in unsound behavior due to the `align` pragma claiming an alignment
+which we don't in practice observe. Avoid this by statically asserting
+that the size is a multiple of the alignment.
+
+(cherry picked from commit b585225be9670de1a83e0bb17034d2fb821cb8a3)
