## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00008
- best_post_interactions: 3
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_culperresearch#beacecb5] $NVDA CEO Jensen Huang met Tuesday with Commerce Secretary Howard Lutnick as the Trump administration investigates potential violations involving Nvidia chip exports to China, according to a source familiar. https://t.co/EmxhMrS5n9 (https://twitter.com/CulperResearch/status/2072367248929353956)
- [x_culperresearch#1822efed] $NVDA Staff Detained by Taiwan in China Chip Smuggling Case https://t.co/w0dMF7RhU3
- [x_culperresearch#a3add9c9] NEW: We are short Tarsus Pharmaceuticals $TARS, maker of XDEMVY, a $2,000 eyedrop for demodex blepharitis. We think XDEMVY rests on a TARS-funded Medicare copay scheme raising serious Anti-Kickback concerns, real TAM is a fraction of the hype, and $TARS whiffs on '26 FY numbers. 
- [x_culperresearch#289d3063] $NVDA CEO Huang declines Elizabeth Warren’s request to testify regarding the Company’s business in China. He is clearly extremely busy with more important matters.
- [x_culperresearch#5af6a240] Tonight in an unusual weekend update, the U.S. Commerce Department restricted $NVDA chip sales to Chinese firms outside China. Reuters cites “hundreds of thousands” of chips may have made their way to Chinese firms. https://t.co/ogK7ZuGF5T
- [x_culperresearch#084a7ed6] NEW: We are short Nvidia $NVDA. We believe Nvidia has a significant China problem. Please see our full report and disclosures now available on our website, link in bio. https://t.co/oTaJyL7S2R
- [x_culperresearch#d034d310] Goodnight
- [x_culperresearch#1a6710d7] Two months since @CorneliaLake last tweeted on $TE. Shares are down 48% since then. Those who can't do, sell newsletters. https://t.co/6EykquuHrZ

- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=76, 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=76, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=110, 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=0.5, freshness_days=76, 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=110, 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.
