## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00735
- best_post_interactions: 61
- 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_williamkast_#588fe428] There are 2 types of creative diversity. 1. Production Format 2. Creative Framework Most leverage only the production format. I.e., Founders ads vs UGC ads vs Static Ads, etc But the creative framework adds just as much creative diversity. For example, you can pick UGC as the pro (https://twitter.com/williamkast_/status/2012240278875234330)
- [x_williamkast_#5bd189b0] No portfolio due to NDAs must be the biggest scam in ecom. People seriously trying to tell they're working in the field for years but have nothing to share.
- [x_williamkast_#893fbe96] 5 ad creative formats that win in every Meta ad account: 1. Founders ads: https://t.co/f20fB4JM4j 2.

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=21, method=llm_persona_from_recent_content
- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=79, 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=79, 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=0.5, freshness_days=79, 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.
