feat(briefs): No.093 A7A5 ルーブル建てステーブルコイン制裁回避（Pillar 04）#618
Merged
Conversation
This week's Brief. Only the A7A5 case from the 2026-07-03 candidate draft was written — the other candidate (No.093 draft on AI chatbot political bias) was dropped after primary-source verification: the WaPo test it cited did NOT include Claude/Anthropic (the draft fabricated Claude's figures), omitted Grok which WaPo actually tested, and its specific percentages weren't in the source. See the draft-review note to the user. A7A5 (Pillar 04 / kyc-aml-disclosure): a ruble-backed stablecoin moved $110B+ on-chain under sanctions — fully traceable, yet no attribute proves/blocks a sender's sanctions status at transaction time; only after-the-fact SDN designations and chain analytics could act. Primary-source verified (per the brief-sourcing discipline), draft corrected on: - OFAC SDN designations are 2025-08-14 (draft said "2026 上期"), 6 entities incl. A7 LLC, Old Vector LLC, Grinex. - Issuer is Old Vector LLC (Kyrgyzstan); A7 LLC is the originator (draft omitted Old Vector). - Volumes confirmed: UK gov ~$90B/yr, CertiK ~$110B cumulative & ~43% of the non-USD stablecoin market, holders 13k→29k; unverified "$1.5B→$0.5B daily" decline dropped in favor of the verified growth-despite-sanctions framing. - EU 20th package adopted 2026-04-23, crypto measures effective 2026-05-24; GENIUS Act PPSI rule proposed 2026-04-08 (Fed Register 2026-04-10). Framed accurately as ongoing-monitoring / freeze-reject mandates — not the attribute-travels-with-the-transaction layer this Brief argues for. Canon: A7A5 front of title/TL;DR, である調, 検出と証明の落差 + 補完 in §5, gap module JA+EN, related_briefs = 077/013/086/021 (KYC/attestation primitive), version 1.0. astro sync + build green, OG images generated.

…CP pair (Pillar 03) (#619) A deliberate pair from the 2026-07-03 additional drafts: both are the same Pillar 03 primitive — an AI coding tool connects "input whose origin it cannot choose" to execution without verifying provenance/authorization before acting. 094 (Cursor) is the read-in-instruction entry point; 095 (Amazon Q) is the bundled-config entry point. Numbering: A7A5 already took 093 (PR #618, open), so this pair is renumbered 094/095; 095's cross-references to Cursor and to itself were updated (draft's 093→094, 094→095), and related_briefs use full slugs. Primary-source verified (gh api on both GHSAs, NVD on the CVEs, all source URLs 200-checked), drafts corrected on: - Cursor CVE-2026-50548/50549: 9.8 confirmed on NVD CVSS 3.1 (GHSA GHSA-3v8f-48vw-3mjx → CVE-2026-50549 "sandbox escape via symlink…", critical); dropped the draft's unverified "CVSS 4.0 9.3". - Amazon Q CVE-2026-12957: score is 8.5 on CVSS 4.0 (GHSA cvss_v4) / 7.8 on NVD CVSS 3.1 — written with both versions (draft's bare "8.5" was the v4.0 score); "AWS recommends 1.69.0" dropped (not in the Wiz/AWS source) → "fix in 1.65.0, update to latest". - The Register URL 404 → removed from 095 sources. - Cross-tool CVEs (Claude Code 2025-59536/2026-21852, Cursor 2025-54136, Windsurf 2026-30615) and the "MCP auto-execution" framing confirmed against the Wiz blog; DuneSlide mechanisms/timeline/paths confirmed against the Cato blog. Format: draft frontmatter converted to the content.config schema (pillar 03-agent-authority, published, related_pack C-agent-governance, slug related_briefs), H1/subtitle/Pillar line dropped, headings numbered 1–9, gap module (gap_detected/missing/fix) + og_lead authored for both JA and EN (drafts had neither), full EN bodies written. 検出と証明の落差 + 補完 in §5, version 1.0. astro sync + build green, OG images generated.

#636 方針（本文に内部 Lemma リンクを置かない）に合わせ、§5 末尾のエッセイ リンクと §7 末尾の Pillar/Seal 参照リンクを JA/EN とも撤去（§5「…前進する。」、 §7「…相補的に働く。」で閉じる）。TL;DR の締めを 099–101 と同じ標準形 「検出と事前証明は代替ではなく補完である。」/「Detection and pre-execution proof are complements, not substitutes.」に統一。astro sync 緑。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FLcqXYL3EEYn5AsrpMV2eE

今週の Critical Brief。2026-07-03 候補ドラフトのうち A7A5 事案のみを執筆（JA/EN）。もう一方の候補（AI 政治的偏り）は一次照合で捏造検出のため見送り（下記）。
採用: No.093 A7A5（Pillar 04 / kyc-aml-disclosure）
ルーブル建てステーブルコイン A7A5 が制裁下でオンチェーン累計 $110B 超を移転 — 取引は完全に追跡可能なのに、送金主体の制裁属性を取引の実行時に証明・遮断する層がなく、事後の SDN 指定・チェーン分析でしか止められなかった、という「検出と証明の落差」。
一次照合と、ドラフトからの訂正
Sources 全 URL 200 確認。
見送り: AI 政治的偏り（ドラフト No.093）— 🔴 捏造検出
WaPo 原記事（2026-06-24）を照合したところ:
捏造・機微テーマ・検証不能の三重リスクのため不採用（詳細はチャットで報告済み。書き直すなら別 PR）。
正典準拠
A7A5 をタイトル/TL;DR 前方 / である調 / §5 に「検出と証明の落差」+「補完」+ detection-is-not-proof リンク / gap モジュール JA+EN / related_briefs = 077・013・086・021（KYC・アテステーションの primitive）/ version 1.0。
検証
astro sync（zod）通過・pnpm build350+ページ成功・JA/EN + OG 画像生成確認マージしない運用のためレビュー後にどうぞ。
