Phase 1: Compiler Backend (Months 1-3)

1.1 Intermediate Representations

Source → AST → HIR → MIR → LLVM IR → Native
              ↓
          Interpreter (existing)

HIR (High-level IR):

Desugar match expressions
Expand macros and prompts
Resolve imports
Normalize control flow

MIR (Mid-level IR):

SSA form
Basic blocks
Explicit drops (ownership)
Monomorphized generics
Inlined small functions

1.2 LLVM Integration

# crates/my-llvm/Cargo.toml
[dependencies]
inkwell = { version = "0.4", features = ["llvm17-0"] }

Key codegen components:

Type lowering (My types → LLVM types)
Function codegen
Effect handling (compile-time erasure)
AI stub generation (runtime dispatch)
Ownership/drop insertion

1.3 Targets

Target	Priority	Notes
x86_64-linux	P0	Primary dev platform
x86_64-darwin	P0	macOS Intel
aarch64-darwin	P0	macOS Apple Silicon
x86_64-windows	P1	Windows
wasm32-unknown	P1	Browser/edge
aarch64-linux	P2	Linux ARM

Effect-annotated APIs

// stdlib/std/fs.my
fn read_file(path: String) -> Result<String, IoError> with IO {
    @ffi("my_fs_read_file", path)
