## (a) Tier 7 AI Pilot 詳細

**ファイル**: `data/open-problems/latest-axioms/technology/ai/` に 100 JSON
**ソース**: arXiv CS.AI 最新 (search_query=cat:cs.AI sortBy=submittedDate)
**Schema**: docs/metadb-v3-0-spec.md §3.4 完全準拠 (4 軸 axiomMeta + epistemologicalProperties)
**D-FUMT₈ tagging**: rule-based v0.1 placeholder (将来 Haiku で再分類予定)
**ID format**: `LATEST-AI-2026-04-24-NNN`

## (b) ingest-latest-axioms.ts ライブラリ

**Exports**:
- `RawSourceEntry`, `IngestOptions`, `DfumtClassification`, `SourceAdapter`
- `ArxivAdapter` クラス
- `ruleBasedClassifier()`
- `normalizeEntry()`
- `ingest()` 主 API

**CLI**: `npx tsx scripts/ingest-latest-axioms.ts --source=arxiv --category=cs.AI --field=technology --subfield=ai --limit=50`

**fieldExpirationDefaults** 自動読み込み (Q2 分野別動的)

## (c) Haiku Classifier

**Model**: claude-haiku-4-5-20251001
**API**: native fetch (no SDK dependency)
**Fallback**: ANTHROPIC_API_KEY 未設定時は rule-based-classifier
**System prompt**: D-FUMT₈ 8 値 + Axis X (4) + Axis Z (4) を一括出力 (JSON 強制)
**Batch CLI**: `--reclassify-tier7 --field=technology/ai`

## (d) IPFS Multi-Pin

**Providers**: local IPFS / Pinata / Web3.Storage / Filebase (Q3 E 決定)
**Env vars**: `PINATA_JWT`, `W3S_TOKEN`, `FILEBASE_TOKEN`
**Log**: `data/p2p/ipfs-pin-log.json` (timestamp + CID + 各 provider 結果)
**Dry-run**: `--dry-run` で安全確認可

## (e) Tier 8 Seed 10 件

**Q5 階層方式**: proven + ref → public (9 件) / conjectured → semi-public (1 件 = P vs NP)

| ID | 分類 | 視認性 |
|-|-|-|
| HALTING | computational | public |
| GODEL-1ST/2ND | logical | public |
| RUSSELL-PARADOX | logical | public |
| TARSKI | logical | public |
| RICE | computational | public |
| LIGHTSPEED | physical | public |
| 2ND-LAW | physical | public |
| HILBERT-10TH | computational | public |
| **PVSNP** | **current-limit** | **semi-public** |

## (f) STEP 993 Brocard n ∈ [51, 100]

**ファイル**: `data/lean4-mathlib/CollatzRei/Step993BrocardExtended100.lean` (142 行)
**Theorems**: 50 sqrt_ne (n=51..100) + 1 aggregate = **51 theorems**
**Build**: `lake env lean ...` exit 0
**累計 Brocard**: 102 theorems + 2 Prop, n ∈ [1, 100], 0 sorry, 0 axiom

## (g) publish-metadb v3.0 動作確認

**変更**: `scripts/build-public-metadb-snapshot.ts`
- `specialDirs` に `latest-axioms`, `impossibility-map` 追加
- `walkTier7()` (Q1 全 public で再帰 copy)
- `walkTier8()` (Q5 visibility-filter, private は除外)
- `writeMetaFiles` 拡張: tier7 / tier8 totals, version 3.0-public
- console log 拡張: 全 8 tier 表示

**実行結果** (2026-04-25):
```
Grand total entries: 2,804
  Tier 1: 2,615 / Tier 2: 15 / Tier 3: 6 / Tier 4: 38
  Tier 5: 7 / Tier 6 public: 13 (excluded: 10)
  Tier 7: 100 / Tier 8: 10
```

公開 snapshot `C:\Users\user\rei-open-problems` に v3.0 反映完了 (commit/push 別途)。

## 4 軸タグ統計 (Tier 7 100 entries, rule-based v0.1)

下記は次の Haiku 再分類で精度向上予定。現状は placeholder。

## Next steps (任意)

- (i) ANTHROPIC_API_KEY 設定 → Haiku 再分類実行 (Tier 7 100 entries)
- (ii) IPFS daemon 起動 + Pinata/W3S/Filebase アカウント作成 → 実 pin 実行
- (iii) Tier 8 を 50-100 件まで拡張 (Mathlib/MML gap detector 自動)
- (iv) Phase M3 残り 13 大分野 ingestion (1,300-1,400 entries 目標)
