feat(llvm): Phase 132-P2 - Dict ctx removal (FunctionLowerContext SSOT completion)
...
Completed SSOT unification for FunctionLowerContext by removing the manual
dict ctx creation and assignment in function_lower.py.
Changes:
- Removed builder.ctx = dict(...) creation (18 lines, lines 313-330)
- Removed builder.resolver.ctx assignment (no longer needed)
- Confirmed instruction_lower.py uses context=owner.context throughout
- Added phase132_multifunc_isolation_min.hako test for multi-function isolation
- Extended phase132_exit_phi_parity.sh with Case C (Rust VM context test)
Testing:
- Phase 132 smoke test: All 3 cases PASS
- Phase 87 LLVM exe test: PASS (Result: 42)
- STRICT mode: PASS
- No regressions: Behavior identical before/after (RC:6 maintained)
Impact:
- Reduced manual context management complexity
- FunctionLowerContext now sole source of truth (SSOT)
- Per-function state properly isolated, no cross-function collisions
- Cleaner architecture: context parameter passed explicitly vs manual dict

feat(joinir): Phase 132-P3 - Exit PHI collision early detection
...
Added verify_exit_phi_no_collision() to contract_checks.rs for early detection
of ValueId collisions between exit PHIs and other instructions.
Problem detected:
- If exit_phi_builder uses builder.value_gen.next() (module-level) instead of
func.next_value_id() (function-level), ValueIds can collide:
Example:
- bb0: %1 = const 0 (counter init)
- bb3: %1 = phi ... (exit PHI - collision!)
Previous behavior:
- Error only detected at LLVM backend runtime
- Cryptic error: "Cannot overwrite PHI dst=1"
New behavior:
- Panic at Rust compile time (debug build)
- Clear error message with fix suggestion:
"Exit PHI dst %1 collides with instruction in block 0
Fix: Use func.next_value_id() in exit_phi_builder.rs"
Benefits:
- 🔥 Fail-Fast: Catch errors during Rust compilation, not LLVM execution
- 📋 Clear messages: Exact collision point + fix suggestion
- 🧪 Testable: verify_exit_phi_no_collision() can be unit tested

feat(llvm): Phase 132 - Pattern 1 exit value parity fix + Box-First refactoring
...
## Phase 132: Exit PHI Value Parity Fix
### Problem
Pattern 1 (Simple While) returned 0 instead of final loop variable value (3)
- VM: RC: 3 ✅ (correct)
- LLVM: Result: 0 ❌ (wrong)
### Root Cause (Two Layers)
1. **JoinIR/Boundary**: Missing exit_bindings → ExitLineReconnector not firing
2. **LLVM Python**: block_end_values snapshot dropping PHI values
### Fix
**JoinIR** (simple_while_minimal.rs):
- Jump(k_exit, [i_param]) passes exit value
**Boundary** (pattern1_minimal.rs):
- Added LoopExitBinding with carrier_name="i", role=LoopState
- Enables ExitLineReconnector to update variable_map
**LLVM** (block_lower.py):
- Use predeclared_ret_phis for reliable PHI filtering
- Protect builder.vmap PHIs from overwrites (SSOT principle)
### Result
- ✅ VM: RC: 3
- ✅ LLVM: Result: 3
- ✅ VM/LLVM parity achieved
## Phase 132-Post: Box-First Refactoring
### Rust Side
**JoinModule::require_function()** (mod.rs):
- Encapsulate function search logic
- 10 lines → 1 line (90% reduction)
- Reusable for Pattern 2-5
### Python Side
**PhiManager Box** (phi_manager.py - new):
- Centralized PHI lifecycle management
- 47 lines → 8 lines (83% reduction)
- SSOT: builder.vmap owns PHIs
- Fail-Fast: No silent overwrites
**Integration**:
- LLVMBuilder: Added phi_manager
- block_lower.py: Delegated to PhiManager
- tagging.py: Register PHIs with manager
### Documentation
**New Files**:
- docs/development/architecture/exit-phi-design.md
- docs/development/current/main/investigations/phase132-llvm-exit-phi-wrong-result.md
- docs/development/current/main/phases/phase-132/
**Updated**:
- docs/development/current/main/10-Now.md
- docs/development/current/main/phase131-3-llvm-lowering-inventory.md
### Design Principles
- Box-First: Logic encapsulated in classes/methods
- SSOT: Single Source of Truth (builder.vmap for PHIs)
- Fail-Fast: Early explicit failures, no fallbacks
- Separation of Concerns: 3-layer architecture
