Seven commits in a single session, and the spotlight is on CX-22, CX-23, and CX-24. They leap ahead in the backend roadmap, laying down the critical components of the differential harness, Cranelift lowering skeleton, and the JIT host boundary contract. These are the essential pieces for any Cx program to run through the JIT path. Meanwhile, the trio of CX-18, CX-19, and CX-20 have successfully merged into submain, wrapping up the array lowering sequence from Phase 11. What Merged CX-20 (PR #70) : This commit delivered array element writes via the IR. Introducing the SemanticLValue::Index variant into semantic analysis, the interpreter, and IR lowering, it ensures that arr:[i] = value and compound assignments like arr:[i] += value function as intended. This involved adding 428 lines across five files. Filed on May 4th, it secured its place in submain today.…
