Phase 29ae: JoinIR Regression Pack (docs-first)
Goal: JoinIR の最小回帰セットを SSOT として固定する。
Regression pack (SSOT)
- Pattern2:
phase29ab_pattern2_* - Pattern2 (real-world):
phase263_pattern2_* - Pattern2 (subset, strict shadow, VM):
phase29ai_pattern2_break_plan_subset_ok_min_vm - Pattern2 (release adopt, VM):
phase29ao_pattern2_release_adopt_vm - Pattern3 (If‑Phi, VM):
phase118_pattern3_if_sum_vm - Pattern3 (release adopt, VM):
phase29ao_pattern3_release_adopt_vm - Pattern4 (continue min, VM):
phase29ap_pattern4_continue_min_vm - Pattern1 (strict shadow, VM):
phase29ao_pattern1_strict_shadow_vm - Pattern1 (subset reject, VM):
phase29ao_pattern1_subset_reject_extra_stmt_vm - Pattern1 (stdlib to_lower, VM):
phase29ap_stringutils_tolower_vm - Pattern1 (stdlib join, VM):
phase29ap_stringutils_join_vm - Pattern5 (Break, VM):
phase286_pattern5_break_vm - Pattern5 (strict shadow, VM):
phase29ao_pattern5_strict_shadow_vm - Pattern5 (release adopt, VM):
phase29ao_pattern5_release_adopt_vm - Pattern6 (strict shadow, VM):
phase29ao_pattern6_strict_shadow_vm - Pattern6 (release adopt, VM):
phase29ao_pattern6_release_adopt_vm - Pattern6:
phase29ab_pattern6_* - Pattern7 (strict shadow, VM):
phase29ao_pattern7_strict_shadow_vm - Pattern7 (release adopt, VM):
phase29ao_pattern7_release_adopt_vm - Pattern7:
phase29ab_pattern7_* - Merge/Phi代表:
apps/tests/phase1883_nested_minimal.hako（RC=9） - この pack が JoinIR 回帰の唯一の integration gate（phase143_* は対象外）
- phase143_* は LoopBuilder 撤去 / plugin disable 固定 / LLVM exe 期待が古いので除外
- phase286_pattern9_* は plugins disabled 経路の mismatch があるため legacy pack 側で SKIP（phase29ae pack には含めない）
- shadow adopt tag（
[coreplan/shadow_adopt:*]）はfilter_noiseで除去される - タグ検証が必要な smoke は raw output（filter 前）を参照する
- タグ coverage SSOT:
docs/development/current/main/design/coreplan-shadow-adopt-tag-coverage-ssot.md
Header PHI Entry/Latch Contract (SSOT)
- Entry preds:
entry_incomingのブロック + host entry block のみ - Latch preds: header の preds から entry preds を引いた残り
- PHI inputs: entry preds は entry 値、latch preds は latch 値を流す
- 根拠:
src/mir/builder/control_flow/joinir/merge/README.md（Phase 29ae セクション） - 修正コミット:
11adec0ab
Commands
./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh
Status
- phase1883: PASS（RC=9 を成功扱い）
- pattern2: PASS（JoinIR main param remap を carrier_order に揃える）
