## Evidence
- [x_yasuotabei#cf5b33f4] Metis: Memory Foundation Model https://t.co/ydBDY6i2Pk 過去の対話履歴を外部ストレージに保存して検索する代わりに、オンライン対話で得た情報をLLM内部の固定サイズのmemory stateへ書き込み、forward passだけで更新・利 用する「Metis: Memory Foundation Model」を提案した論文。 ・扱っている問題 現在のLLMは、対話中に得たユーザー固有の情報やタスクの進捗を、モデル内部の状態として継続的に保持できない。 そのため、過去の情報を利用するには、会話履歴を再入 (https://twitter.com/yasuotabei/status/2072479924292898854)

Every inferred field below carries how it was produced. Facts stay facts; inferences stay inferences.

- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=80, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.
- commercial.promotion_intent: source_type=ai_inferred, confidence=0.6, freshness_days=80, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=108, method=profile_snapshot_and_engagement_ratio_heuristic — Means "worth a manual check", NOT confirmed fraud. Flags can be wrong and are not a verdict about the person.
- quality.authenticity_score: source_type=heuristic, confidence=0.25, freshness_days=80, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — The input set differs by platform; do not compare this score across platforms.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=108, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
