# Self Current Task — Now (main)
## Current Focus: Phase 29af (Pattern2 Boundary Hygiene)
## Current Focus: Phase 29af（Boundary Hygiene SSOT 固定）
**2025-12-29: Phase 29af P1 完了** ✅
- 目的: boundary hygiene を merge 入口（`contract_checks`）へ集約して再発検知を SSOT 化（仕様不変）
- 実装: `src/mir/builder/control_flow/joinir/merge/contract_checks/boundary_hygiene.rs`（strict/dev のみ）
- 配線: `src/mir/builder/control_flow/joinir/merge/contract_checks/boundary_creation.rs`
- 検証: `cargo build --release` / `./tools/smokes/v2/run.sh --profile quick` / `./tools/smokes/v2/run.sh --profile integration --filter "phase29ab_pattern2_"` / `./tools/smokes/v2/run.sh --profile integration --filter "phase1883_"` PASS
**2025-12-29: Phase 29af P0 完了** ✅
- 目的: Pattern2 の boundary 情報の歪みを SSOT 化し、exit/header/latch の責務境界を固定（仕様不変）
