## Identity
- platform: x
- handle: Mathilda_Sun_
- platform_url: https://twitter.com/Mathilda_Sun_
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 2757
- following: 5923
- posts_total: 122
- posts_observed: 5
- posts_per_day: 0.066
- account_age_days: 1856
- verified: true
- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00472
- best_post_interactions: 13
- 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_mathilda_sun_#9b71736e] Hide the chain (https://twitter.com/Mathilda_Sun_/status/2064357027355529629)
- [x_mathilda_sun_#a8057069] 🫡
- [x_mathilda_sun_#42604e35] both still ignore cricket - $150B annual betting turnover, zero serious onchain markets. FIFA got the marquee deal but the real surface area is elsewhere.
- [x_mathilda_sun_#b8ffa518] People really don’t understand the scale of the Chinese “reselling” economy - from every AI model to SaaS tools like similarweb to Meta ad accounts to all kind of social media accounts to email addresses to KYCs…..the list goes on. Internet censorship by the CCP and geo blocking 
- [x_mathilda_sun_#38468bda] yep
- [x_mathilda_sun_#0cb1b6ce] 🟠
- [x_mathilda_sun_#f20edb17] sportsbooks, Kalshi, Polymarket, @TipRun_Markets🤔?

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

- audience.description: source_type=ai_inferred, confidence=0.4, freshness_days=67, method=llm_persona_from_recent_content
- audience.roles: source_type=ai_inferred, confidence=0.4, freshness_days=67, method=llm_persona_from_recent_content
- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=67, 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=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=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=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.
- reach.followers: source_type=observed, confidence=0.95, freshness_days=110, method=platform_profile
