| ## Complete Pipeline Verification |
|
|
| ### Data Flow: ✅ VERIFIED |
|
|
| ``` |
| SOURCE CODE (.hy file) |
| ↓ |
| [Agent 1: hybrid_lexer] → TOKENS |
| ↓ |
| [Agent 1: hybrid_parser] → AST (hybrid_ast) |
| ↓ |
| [Agent 3: hybrid_normalizer] → NORMALIZED IR (hybrid_ir) |
| ↓ |
| [Agent 2: hybrid_codegen] → SUBLEQ BINARY |
| ↓ |
| [Agent 3: hybrid_optimizer] → OPTIMIZED BINARY |
| ↓ |
| [SUBLEQ VM: subleq_bf] → OUTPUT + STATE |
| ``` |
|
|
| **Status**: All interfaces present and correctly positioned. |
|
|
| ### Integration Points: ✅ VERIFIED |
|
|
| 1. **Parser → AST**: Agent 1 outputs `AST` type ✅ |
| 2. **AST → IR Normalization**: Agent 3 `hybrid_normalizer` ✅ |
| 3. **IR → Codegen**: Agent 2 accepts normalized IR ✅ |
| 4. **Codegen → SUBLEQ**: Agent 2 outputs `seq[int]` (memory image) ✅ |
| 5. **SUBLEQ → Optimizer**: Agent 3 `hybrid_optimizer` ✅ |
| 6. **Optimizer → VM**: Uses existing `subleq_bf` ✅ |
| 7. **VM → Testing**: Agent 3 test frameworks use `runSubleq()` ✅ |
|
|
| ### File Dependencies: ✅ VERIFIED |
|
|
| ``` |
| hybrid_lexer.nim |
| ↓ (uses) |
| hybrid_ast.nim ← hybrid_parser.nim imports |
| ↓ |
| hybrid_compiler.nim (orchestration) |
| ↓ |
| hybrid_codegen.nim (Agent 2) |
| ↓ |
| subleq_bf.nim (existing SUBLEQ VM) |
| ↓ |
| test_agent3_*.nim (verification) |
| ``` |
|
|
| **Status**: All dependencies resolved, no circular imports. |
