Code quality improvements after Phase 285A1 implementation: **Task 1: Dead Code Cleanup** - Removed unnecessary #[allow(dead_code)] from emit_weak_load() - Function is actively used in weak_to_strong() method handler **Task 2: Unused Import Removal (cargo fix)** - edgecfg/api/mod.rs: Removed seq, if_, loop_, cleanup, verify_frag_invariants - pattern3.rs: Removed BinaryOperator - pattern2/api/mod.rs: Removed PromoteStepResult - jump.rs: Removed EffectMask, Span - Result: 6 unused imports eliminated **Task 3: Deprecated Pattern Removal** - Fixed 4 PlanKind::LoopWithPost deprecated warnings - Updated to Phase 142 P0 architecture (statement-level normalization) - Files: normalized_shadow_suffix_router_box.rs, routing.rs, execute_box.rs, plan.rs - Removed 2 deprecated tests: test_loop_with_post_* **Task 4: WeakFieldValidatorBox Boxification** - Extracted weak field validation logic into dedicated Box - New file: src/mir/builder/weak_field_validator.rs (147 lines) - fields.rs: 277 → 237 lines (-40 lines, -14.4%) - Added 5 unit tests for validation logic - Follows Phase 33 boxification principles (single responsibility, testability, reusability) **Metrics**: - Code reduction: -40 lines in fields.rs - Test coverage: +5 unit tests - Warnings fixed: 4 deprecated warnings - Imports cleaned: 6 unused imports 🤖 Generated with Claude Code Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
JoinIR → VM bridge layer
Responsibilities:
- Convert normalized JoinIR modules into MIR for the Rust VM without changing semantics.
- Provide a thin runner helper that executes a JoinIR entry via the VM.
- Host experimental metadata-aware paths (Phase 40-1) behind clearly marked helpers.
Boundaries:
- No new control-flow semantics or heuristics here; this layer only maps structures already normalized by JoinIR.
- Keep type information minimal (MirType::Unknown) and avoid adding inference or guessing.
- Debug/diagnostic output must stay behind
