name: META-DB v3.0 Plan B — Lean 4 progress + Session log auto-pipeline (2026-04-25)
description: ★★★ 2 つの自動取込 pipeline 完成: scripts/ingest-lean4-progress.ts (133 .lean → Tier 8) + scripts/log-session-summary.ts (構造化サマリ → Tier 7 90 日 rolling). rei-learning-cycle.bat Phase 8a/8b に統合. Tier 7=101, Tier 8=143, 全 2,938 entries.

## 完成した自動 pipeline

### B-1: Lean 4 progress ingest (Tier 8)

**File**: `scripts/ingest-lean4-progress.ts`

**動作**:
1. `data/lean4-mathlib/CollatzRei/*.lean` を 133 ファイル全 scan
2. theorem / lemma / def / sorry / axiom 数を regex 抽出
3. Mathlib import path 解析
4. .olean build artifact 存在確認 (build status)
5. Tier 8 `lean4-mathlib-mml/{closed-by-rei,partial,world-open}/` に 1 entry/file

**初回 run 結果 (2026-04-25)**:
- Files: 133
- Closed by Rei (zero sorry/axiom): **64**
- Partial (sorry > 0 or axiom > 0): 66
- Open / scaffold: 3
- Total theorems: **1,996**
- Total sorry residual: **9**
- Built (.olean): 88 / 133

### B-2: Session summary logger (Tier 7)

**File**: `scripts/log-session-summary.ts`

**動作**:
1. 当日の git commit を scan (`git log --since="YYYY-MM-DD 00:00"`)
2. 各 commit の touched files を集計 (lean / ts / json / md / other)
3. 新 theorem 推定 (git diff +theorem/+lemma)
4. classification 自動判定 (impl / design / fix / research / docs / mixed)
5. Tier 7 `development/sessions/{date}.json` に 1 entry/day
6. **90 日 rolling window**: 古い entry は `sessions-archive/` に自動移動

**重要方針**:
- **全文チャットログは保存しない** (容量・プライバシー両面の懸念)
- 構造化サマリのみ (commit hash + 数値指標 + 200-500 字 summary)
- 容量試算: 1 KB/日 × 90 日 = ~90 KB の rolling capped storage

**初回 run 結果 (2026-04-24 UTC = 04-25 JST)**:
- Commits: 26
- New theorems detected: 100
- New files: 11 lean / 59 ts / 383 json / 9 md / 99 other
- Classification: fix (last commit was 黒画面修正)

### B-3: Daily wiring

**File**: `scripts/rei-learning-cycle.bat`

新規 phase 追加:
- **Phase 8a**: `ingest-lean4-progress.ts`
- **Phase 8b**: `log-session-summary.ts --auto`
- (既存) Phase 9: `publish-metadb.ts`

→ 毎日 14:10 JST に自動実行 (既存 Windows Task Scheduler)

## META-DB 現況 (2026-04-25)

```
Tier 1: 2,615
Tier 2:    15
Tier 3:     8
Tier 4:    38
Tier 5:     7
Tier 6:    13 (public; 10 semi/private excluded)
Tier 7:   101 (100 AI + 1 session log)
Tier 8:   143 (10 seed + 133 lean4-mathlib-mml)
─────────────
Grand:  2,938 entries
```

## サイト UI (次回 task C で対応)

現在の MetaDBExplorer は Tier 7 を `technology/ai/` 限定で表示。次回:
- Tier 7 内の `development/sessions/` を別タブで表示
- Tier 8 内の `lean4-mathlib-mml/{closed,partial,open}` を別タブで表示
- 「Lean 4 進捗」「開発ログ」のサイト UI 拡張

## 容量見積

| Phase | 増分 |
|-|-|
| Lean 4 progress (133 entries × ~3 KB) | ~400 KB total (固定 — file 数しか増えない) |
| Session log (1 KB × 90 日 rolling) | ~90 KB max |
| **合計増分** | < **500 KB / 永続** |

GitHub 制限 (2 GB) 内で長期運用可。
