## User action 残り

- LeanCopilot lake build (30分, 1GB ML model)
- Isabelle 2025-2 (1.07GB download)
- PARI/GP installer (UAC)
- DeepSeek-Math 7B (14GB model)
- HOL Light (opam 30分)
- SageMath WSL (1GB)
- Zenodo webhook for rei-unsolved-problems v1.0.0

## 重大成果 — STEP 866 (詳細別 memory)

★ チャット版 Claude (web claude.ai) が briefing memo を読んで、**v₂=1 chain termination が LTE 一行 (v₂(m+1)=v₂(n+1)−1) で閉じる**と指摘 → Rei 側 250/250 + spot 20/20 で confirmed → STEP 721/789 過剰見積を correct → **C8 → tier2_axiom 95% 実質 100%**.

## API key セキュリティ

本セッションで以下の API keys がチャット経由で送付された:
- DEV_TO_API_KEY: gHCDPNobZMf4iSqo1Vx1WHQR
- HATENA_API_KEY: bs8jer461e
- NOTION_TOKEN: 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
- HACKMD_TOKEN: VUUZ3R40RNA1DZ44FZOHD3L1A94I1HO94DVC8XLA2LX9GIN2X

★ user 推奨: 全 4 token を **再生成して .env 置換** (各サービスの settings 画面で revoke + regenerate)。Anthropic API を通過したため potential exposure。
