IR and Runtime Design

Analyze $ARGUMENTS as a compiler architecture problem.

Required workflow

1. Read the current architecture docs and relevant implementation files.
2. State the user-visible or compiler-internal pressure that motivates the change.
3. Define the boundary under discussion:
   • AST to HIR
   • HIR to MIR
   • MIR to backend
   • runtime service boundary
   • ABI / FFI boundary
4. Compare at least two credible designs if the decision is foundational.
5. Prefer the smallest stable contract that unblocks v1.
6. Record consequences for:
   • optimization
   • diagnostics
   • backend targets
   • stdlib design
   • testing strategy
   • future language features
