refactor(joinir): Phase 287 P2 - Modularize contract_checks (facade pattern)
...
- contract_checks.rs (846行) を facade 化
- 6モジュールへ分割（1 module = 1 contract）:
- terminator_targets.rs (208行) - Branch/Jump検証
- exit_bindings.rs (35行) - exit_bindings ↔ exit_phis
- carrier_inputs.rs (145行) - carrier_inputs完全性
- boundary_creation.rs (160行) - B1/C2不変条件
- entry_params.rs (317行) - Entry param一貫性
- mod.rs (30行) - Facade
- Total: 846 → 895行（+49行モジュール境界オーバーヘッド）
- 意味論不変: エラータグ/ヒント文すべて保存
- Fail-Fast遵守: silent fallback追加なし
- 検証: Build 0 errors / Pattern6 RC=9 / quick 154/154 PASS

fix(joinir): Phase 287 P2 - Pattern6 nested loop latch overwrite fix
...
Fix infinite loop in Pattern6 (nested loop minimal) caused by main→loop_step
overwriting k_inner_exit→loop_step latch values.
Root cause: JoinIR main entry block was incorrectly treated as BackEdge,
causing it to overwrite the correct latch incoming values set by the true
back edge (k_inner_exit → loop_step).
Solution:
- Restrict latch recording to TailCallKind::BackEdge only
- Treat only MAIN's entry block as entry-like (not loop_step's entry block)
- Add debug_assert! to detect double latch set in future
Refactoring:
- Extract latch recording to latch_incoming_recorder module (SSOT)
- Add boundary.loop_header_func_name for explicit header identification
- Strengthen tail_call_classifier with is_source_entry_like parameter
Tests: apps/tests/phase1883_nested_minimal.hako → RC:9 (was infinite loop)
Smoke: 154/154 PASS, no regressions

refactor(joinir): Phase 287 P2 - Strengthen BackEdge/latch conditions (WIP)
...
**Problem**: Phase 188.3 Pattern6 (nested loop) encounters infinite loop
- inner_step → inner_step (self-recursion) incorrectly classified as BackEdge
- → redirects to outer header (loop_step) instead of inner_step entry
- is_recursive_call causes inner recursion to overwrite outer latch values
- → PHI receives wrong values → i doesn't increment → infinite loop
**Fix 1: BackEdge classification strictness** (tail_call_classifier.rs)
- Add `is_target_loop_entry` parameter to classify_tail_call()
- BackEdge ONLY when target==loop_step (entry_func), not inner_step
- Prevents inner_step → inner_step from redirecting to outer header
**Fix 2: latch_incoming guard** (instruction_rewriter.rs)
- Change condition from `is_recursive_call || is_target_loop_entry`
to `is_target_loop_entry` only
- Prevents inner_step self-recursion from overwriting outer loop's latch
- set_latch_incoming() now called with correct values (verified by debug)
**Status**: 🚧 WIP - Infinite loop still occurs
- set_latch_incoming('i', BasicBlockId(8), ValueId(21)) ✅ Called correctly
- But final PHI: `phi [%4, bb8]` instead of `phi [%21, bb8]` ❌
- Root cause likely in PHI generation (merge/mod.rs), not latch_incoming
- Next: Investigate why latch_incoming values aren't used in PHI
**Files**:
- src/mir/builder/control_flow/joinir/merge/tail_call_classifier.rs
- src/mir/builder/control_flow/joinir/merge/instruction_rewriter.rs
