Phase 11 just introduced compound assign lowering on submain, pulling +=, -=, *=, /=, and %%= into the IR backend. All in all, 126 new lines in src/ir/lower.rs and three fresh tests. These operators mark their maiden voyage through the IR backend, and while main keeps its 78/78 green tests, submain stays ahead by 22 commits with a 33-day bridge to cross. Commit 9015aff on submain is the sentinel.
Two sub-packets landed on submain today, moving the IR backend closer to supporting structs properly. The first package upgrades the instruction set to handle memory operations, and the second implements a struct registry integrated into the lowering pass. Together, these changes allow the lowering pass to recognize and manipulate the structs' memory representations, setting the stage for future s
