主に①新規資格ガイドのNext.js App Router移行とデザイン完全復元、②トップページ(ホーム)およびナビゲーションUIの刷新・最適化、③ビルド安定化のためのフォント完全セルフホスト化、④AIエージェント・TDD開発パイプラインのルール強化と自動化テスト整備が実施されました。


カテゴリ別・詳細要約

1. 新規学習ガイドの Next.js 移行 & デザイン完全復元

元HTML/Markdown資料から TDD サイクル(Step 0 Inventory → Step 1 Fail → Step 2 Pass → Step 3 Refactor)を厳格に適用し、複数資格のガイドページを移植・復元しました。

  • CompTIA Network+ (N10-009 / V9) 完全ガイド
    • 元HTMLからドメインカード、Statグリッド、テーブル、Tabler Icons、Mermaid図解を含む100%忠実なデザイン復元。
    • Mermaid図解の拡大・枠外はみ出しを防止する preserveNaturalScale プロパティ対応。
  • Google Cloud PCNE (Professional Cloud Network Engineer)
    • Section 1 (VPC Design ガイド): サイドバーのスクロールスパイ(アクティブリンクのハイライト)およびフッター表示の修正。
    • Section 2 (VPC Implementation ガイド): 100%のデザイン復元に加え、動的カウント付きインタラクティブ・チェックリスト機能を新規実装。
  • Cisco 資格ガイド群 (DevNet / CCNA)
    • Cisco Certified DevNet Associate (200-901 / CCNA Automation) および DevNet Professional 徹底解説ガイドの移植・ルーティング統合。
    • CCNA Network Fundamentals 入門ガイドの移植。
    • Cisco 認定名称・分類(Automation / Infrastructure等)の集中管理化およびアクセシビリティ向上。

2. ホームページ(Top Page)とナビゲーション UI の大幅刷新

  • 動的コンテンツカウント: 定数固定だったアクティブ試験数などのステータス表示を EXAMS データから動的計算する仕組みへ移行。
  • コンポーネント分割: page.tsx の肥大化を防ぐため、Landing Page の各セクション(Hero, ExamCard, ExamCatalog, Stats)を分離抽出。
  • ナビゲーション強化: プロバイダーごとのブランドマークを表示する ProviderMark コンポーネントの追加と、Header Drawer ナビゲーションのレスポンシブ・表示最適化。

3. フォント基盤の完全セルフホスト化(@fontsource 移行)

  • Google Fonts 依存の脱却: 外部通信に起因する Netlify CI や Docker ビルドの突然の失敗(Failed to fetch <family>)を防ぐため、すべてのフォント(Noto Sans JP, JetBrains Mono, DM Sans 等)を @fontsource / @fontsource-variable パッケージによるローカルセルフホスト構成へ完全移行。
  • テストの整備: app/layout.tsx 等でのフォント直参照・直importを監視・検証するテスト (self-hosted-fonts.test.ts) を追加。

4. 学習ドキュメント & チャレンジラボ解説の拡充

  • AGWA (Associate Google Workspace Administrator): ドライブ復旧手順、セキュリティアクセス制御、エンドポイント管理など Section 5 & 6 に関する学習ガイドの追加・補正。
  • GCP チャレンジラボガイド: Chrome Enterprise Premium、NCC (Network Connectivity Center)、Cymbal Chat / Cymbal Cars センシティブデータ保護などのハンズオン解説ドキュメントの新規作成・整理。

5. 開発パイプライン・品質管理・AIエージェントルールの強化

  • 3系統設定ファイルのミラー同期自動化: .agents/, .claude/, .gemini/ 間でのルール・スキル設定のズレを検出する自動バイト照合テスト (agent-mirror-sync.test.ts) を導入。
  • 移行ワークフロー(Invetory / Gate)の厳格化: 不完全な移行や空のステージを排除するため、migration-inventory 抽出口座やコミット認可チェックの判定基準を強化。
  • カバレッジダッシュボードの修正: Cisco CSS のテーマ分類や P0 アクションの判定基準を揃え、カバレッジメトリクスの整合性を維持。

binauthz-attestation を Cloud Build step として直接実行してください。

binauthz-attestation のスクリプトは docker pull と docker inspect を実行します。docker run の内側では必要な Docker socket と Artifact Registry 認証が渡らないため、Attestation 作成が失敗します。name にdigest固定したカスタムビルダーを指定し、引数を直接渡してください。

脆弱性修正版へ更新し、依存関係を監査してください。

Flask 3.0.3 と Werkzeug 3.0.4 には既知の OSV 脆弱性があります。Werkzeug 3.0.6 にも脆弱性情報が残るため、安全基準に使用できません。互換性テストの対象を Flask 3.1.3、Werkzeug 3.1.8 などのサポート済みバージョンへ更新してください。Gunicorn 23.0.0 は脆弱性修正済みと断定せず、サポートポリシーと互換性テストに基づいて選定してください。選定後は、実際に解決される全依存関係を pip-audit などで監査し、Artifact Analysis の再スキャンで CRITICAL 脆弱性がないことを確認してください。

Inline comments:
In `@Gcp-vpc-network-challenge-lab-guide.md`:
- Line 189: Update the diagram around the fw-allow-ssh and fw-allow-icmp rules
so equal-priority, same-action rules are shown without a fixed evaluation order.
Keep both rules at priority 1000 and represent them as unordered alternatives
rather than a sequential flow.

In `@Secure-cicd-pipeline-guide.md`:
- Around line 463-472: Update the curl command in the 認証必須のまま動作確認する section to
include --fail, --silent, and --show-error, ensuring authentication failures and
server errors produce a failed command result while retaining the existing
Authorization header and service URL.
- Around line 285-289: Set REVIEWED_COMMIT_SHA to the reviewed commit SHA before
running git checkout, then update the checkout command to use git checkout
--detach "$REVIEWED_COMMIT_SHA". Preserve the subsequent rev-parse and
BUILDER_IMAGE steps so the builder image remains tied to the checked-out commit.
- Around line 291-294: Update the digest references in the documented
builder-image configuration, including the section around the shown gcloud
command and the corresponding lines 376–379, so the digest value is used
directly with @ rather than adding another sha256: prefix. Preserve the existing
gcloud artifacts describe command, which already returns the complete
sha256:-prefixed digest.

In `@Sensitive-data-protection-challenge-lab-guide.md`:
- Around line 463-471: Document the test prerequisites before the standalone
assertions: instruct readers to execute the earlier definitions of
contains_sensitive_info and generate_guarded_response, and configure PROJECT_ID
with a project that has DLP API access before running the VIN test.
- Around line 459-471: DLP APIを直接呼び出すcontains_sensitive_info周辺のテストを単体テストではなくDLP
API統合テストとして扱い、見出し・説明・コメントの表記を更新してください。generate_guarded_responseを使う統合テストも同様にAPI統合テストとして明記し、単体テストとして残す場合のみDlpServiceClientをモックして検出結果を固定してください。
- Around line 424-431: Wrap the response.text access in the existing
response-validation flow with try/except ValueError, returning blocked_response
when the SDK raises or when the resulting text is empty. Preserve the current
STOP finish-reason check and normal stripping behavior.
