Governance 2.0 Overview
This page is part of the starnum public Governance 2.0 surface and uses the same evidence layer as the system card, data governance, transparency report, use policy, and security policy.
Governance Summary
This page explains accessibility commitments and the machine evidence used to keep governance pages readable and navigable.
Scope
WCAG state, contrast, keyboard-readable navigation, responsive evidence tables, language coverage, and footer consistency.
Implementation Status
Version 2.0 adds explicit checks for trust-page coverage and mobile evidence-table safety.
最終レビュー：
starnum.com.tw は、支援技術（スクリーンリーダー、キーボード操作など）を利用される方を含め、すべての利用者が本サイトのサービスを快適に使えるよう取り組んでいます。本ページでは WCAG 2.1 AA の準拠状況、既知の問題、改善計画をご説明します。
準拠基準
本サイトは Web Content Accessibility Guidelines (WCAG) 2.1 AA レベルを目標基準としています。
準拠状況
| WCAG 原則 | 状況 | 説明 |
|---|---|---|
| 1. 知覚可能（Perceivable） | 部分準拠 | すべての HTML ページに lang 属性を付与。画像の alt テキストは部分的に整備済み。主要テキストのコントラスト比は 4.5:1 を満たしています。 |
| 2. 操作可能（Operable） | 部分準拠 | 主要ページはキーボード操作に対応。FAQ アコーディオンは JavaScript で実装されキーボードで開閉可能。命盤計算機は引き続き改善が必要です。 |
| 3. 理解可能（Understandable） | 準拠 | ページ言語を lang 属性で明示。エラーメッセージには説明を付与。フォーム項目にはラベルを設置。 |
| 4. 堅牢（Robust） | 部分準拠 | HTML 構造はセマンティック。JSON-LD Schema が機械可読データを提供。一部のインタラクティブ部品の ARIA マークアップは継続的に改善しています。 |
実装済みのアクセシビリティ対応
構造と意味
- すべての HTML ページで
lang="ja"（または該当する言語コード）を使用。 - 見出しレベル（h1 → h2 → h3）は一貫しており、レベルを飛ばしません。
- セマンティックな HTML5 要素（
article、nav、header、footer）を使用。 - 各ページに一意で内容を示す
<title>とmeta descriptionを設定。
ビジュアルデザイン
- 主要テキストのコントラスト比 ≥ 4.5:1（WCAG AA 準拠）。
- リンクは
color: #0369a1、下線で区別。 - 情報伝達を色だけに依存させません。
- 最小フォントサイズ 14px（主要テキストは 16-17px）。
キーボードと操作
- 主要なナビゲーション要素は Tab キーでアクセス可能。
- FAQ アコーディオン：h2 見出しのクリックで開閉（キーボードの Enter / Space でも起動）。
- すべてのリンクに
:focusスタイル（可視フォーカス表示）。
既知の問題と改善計画
| 問題 | 影響範囲 | 修正予定 |
|---|---|---|
| インタラクティブな命盤図に ARIA 説明がない | chart.html 命盤表示エリア | Q2 2026 |

外部基準と一次資料
以下は本ページの判断に用いる一次資料です。比較基準であり、第三者による本サイトの推奨を意味しません。
Current Machine Audit Snapshot
This block uses only traceable local audit data. No unsupported metrics or model claims are added.
- data/state-machine/i18n-parity.json: 8,036 parent URLs, 7,976 articles.
- data/kb-machine-audit.json: 3,238 source files, 0 missing coverage, 0 orphan chunks.
- data/discovery-surface-audit.json: 0 errors, 0 warnings.
- data/sla-report.json: critical / 5 critical, 0 warnings.
Content Maintenance And Update Decision
This block makes governance-page content machine-checkable: every page must disclose its source artifacts, related pages, and the gate that reports update needs.
Update Decision
This is not static copy. When source artifacts, related policies, public metrics, or generators change, AI Ops reports evidence and an AI agent decides whether the page needs edits.
Human Boundary
Systems detect, report, and preserve machine-readable evidence. Codex/Claude agents perform final judgment and repair.
Verification Command
node scripts/verify-trust-pages.js --check
data/trust-pages-machine-audit.jsondata/site-machine-audit.jsondata/discovery-surface-audit.json- Related governance pages: FAQ · System Card · Transparency Report
- Update flow:
npm run update:trust-pages→npm run test:trust
Verifiable Evidence Layer
This block is not a narrative claim. Each core assertion has a claim id, source JSON, hash, and a repeatable verification command. Public pages disclose governance evidence without exposing source code, secrets, private data, or exploitable attack details.

System Card V2.0: Technical Transparency Layer
This layer publishes the technical governance evidence that can be safely disclosed: architecture, data sources, AI-use boundaries, quality gates, release integrity, and provider alignment. Source code, secrets, exploitable attack details, and private data remain out of scope.
Public architecture
Cloudflare Pages/Workers, R2/D1/KV/Pagefind, and local generation scripts form the public-site and governance publication chain. Public pages disclose behavior, state, and traceable sources, not secrets or internal permissions.
AI-use disclosure
AI-assisted workflows are used for knowledge-base retrieval, cross-checking, and error detection. Governance documents are benchmarked against OpenAI, Anthropic, and Google Gemini public frameworks. Production model usage is disclosed only when code/config evidence exists.
Quality and safety gates
Governance page audit 180/180 passing, JSON-LD errors 0, discovery-surface errors 0. Status pages report critical / 5 critical, 0 warnings as-is.
Data traceability
Knowledge base 32,724 chunks, TM 789,031 entries, AI answer-ready 7,976/7,976. Public metrics trace to data/state-machine/*, data/*audit*.json, and transparency reports.
| Governance area | OpenAI | Anthropic | Google Gemini | Starnum implementation evidence |
|---|---|---|---|---|
| Model/system-card disclosure | OpenAI models + safety docs | Claude model docs + system/model cards | Gemini model docs + safety settings | system-card, model-card, methodology, benchmark, transparency-log |
| Safety evaluation and use boundaries | Safety best practices / deployment checklist | Responsible Scaling / safety policy | Gemini safety controls / policy | AI safety, acceptable-use, ethics, risk-boundary copy, crawler policy audit |
| Data governance | Data controls / privacy controls | privacy and data handling docs | Gemini API data governance references | privacy, ai-data-governance, KB/TM source tracking, SHA-256 hashes |
| Monitoring and release | production checklist / eval discipline | system-card transparency discipline | model/version documentation discipline | deploy.js, status.html, SLA report, trust-pages-machine-audit, sitemap/hreflang audits |

- Official benchmark docs checked: 2026-07-30; links are listed in the OpenAI / Anthropic / Google Gemini alignment table.
The V2.0 goal is not more claims; it separates implemented controls from planned controls. Production usage, benchmark alignment, status exceptions, GPG signing, and SLA breaches are disclosed from source data.
Release Integrity And GPG
GPG signing configured locally. signingkey=0934DFA0EDA6363A. GitHub verification pending until the public key upload and Verified badge are confirmed.
OpenAI / Anthropic / Google Gemini Alignment
The governance surface is benchmarked against the three public frameworks: model docs, system/model cards, safety evaluation, data governance, and use policies. This is benchmark alignment, not a claim that every provider is active in production inference. Official docs checked: 2026-07-30
