- country: UM
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 1156
- following: 1196
- posts_total: 28232
- posts_observed: 28
- posts_per_day: 4.227
- account_age_days: 6679
- verified: true
- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00519
- best_post_interactions: 6
- 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_assafbar#6536ede7] Shipped v25 of https://t.co/XIohrKOTLd. 50+ new agents, 303 -> 360. Each earned its spot the same way: my agents or I tested it, used it, and it held up. OpenAI Codex CLI, Microsoft MarkItDown, IBM Docling, Crawl4AI are the least cool names - trust us. Stars pulled live from the  (https://twitter.com/assafbar/status/1949728950315544890)
- [x_assafbar#2d587de5] Many such cases:
- [x_assafbar#a827b989] Indeed https://t.co/jDqj70qq4u
- [x_assafbar#30cb161c] Tried/tested Buzz, room to grow
- [x_assafbar#9dfed319] Rediscovering cursor with grok 4.5, and I like it
- [x_assafbar#aaf1a80c] It's not the how, it's the what (you do with the models), go team!
- [x_assafbar#3a79d2dd] https://t.co/yAwgzKkQQ6
- [x_assafbar#0dc8e89a] "You" calling my software "AI slop" wasn't discouraging - it was informative. Not about my product, but about the lens you're choosing to judge builders through.

## 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=21, method=llm_persona_from_recent_content
- audience.roles: source_type=ai_inferred, confidence=0.4, freshness_days=21, method=llm_persona_from_recent_content
- 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=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=0.5, 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=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.
