EN-PARITY-W3-ARTICLE-W9-QA-01: independently QA the frozen Article package

[fermatmind]

What changed

• Added fresh independent W9 authority evidence for exact Article package 213736b1d59a862e73dcfeae77b67cae1fe2b092f41469a57c91631cdb052157 under generated/en-content-parity/W9-independent-qa/articles/w3-articles-213736b1/.
• Reviewed all 17 registered Article assets, all 86 source Markdown table groups / 610 table lines, exact source identities, links, media policy, page/API applicability, claims, field leakage, and eight row-level checks.
• Recorded a strict BLOCKED verdict and a candidate transition limited to package_frozen -> blocked.
• Updated the existing EN-PARITY-W3-ARTICLE-W9-QA-01 ledger item for this fresh run.

Why

Fresh independent W9 found reader-visible English naturalness defects in 7/17 rows: W3-ARTICLE-03, W3-ARTICLE-51, W3-ARTICLE-52, W3-ARTICLE-53, W3-ARTICLE-55, W3-ARTICLE-58, and W3-ARTICLE-59. The remaining 10 rows pass all eight checks. qa_pass is therefore not authorized.

Validation

• pnpm dlx node@24.18.1 scripts/seo/validate-en-content-parity-control.mjs --artifact generated/en-content-parity/W9-independent-qa/articles/w3-articles-213736b1/independent_qa_report.json
• pnpm dlx node@24.18.1 scripts/seo/validate-en-content-parity-control.mjs --artifact generated/en-content-parity/W9-independent-qa/articles/w3-articles-213736b1/master_manifest_patch.candidate.json
• pnpm dlx node@24.18.1 node_modules/vitest/vitest.mjs run tests/contracts/en-content-parity-control-master.contract.test.ts tests/contracts/en-content-parity-w3-article-package.contract.test.ts — 66/66 passed
• Complete JSON/JSONL parsing, exact eight-file SHA recomputation, 17/17 identity and row coverage, exact seven-row blocker aggregation, 86/610 source/candidate table coverage, zero Han leakage, all-false permission checks, and artifact SHA checks — passed
• Byte-identical frozen package comparison and producer package / CONTROL master immutability checks — passed
• git diff --check
• git diff --cached --check
• Exact changed-file scope validation — passed

Intentionally deferred

• Producer package corrections for the seven blocked rows
• CONTROL acceptance or rework reset
• CMS import, publication, runtime, sitemap/llms, indexability, search, and deploy actions
• W3 Career Guides

Repository rule impact

No authority change. This PR records independent W9 gate evidence only. The backend/CMS remains authoritative, and all write/release permissions remain false.
