## Reach
- followers: 23532

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00136
- best_post_interactions: 32
- 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_sebastianroehl#0dd4ae73] FocusKit's July revenue wasn't good, wasn't bad either. Happy to keep it stable at ~$500 per month right now. https://t.co/YnnWRlGe37 (https://twitter.com/SebastianRoehl/status/1997631298769158216)
- [x_sebastianroehl#35b47b7f] Feels like tooting my own horn, but I have to say, I really love the new FocusKit Mac companion app I've been building 😎 https://t.co/QnOsuAB61c
- [x_sebastianroehl#0e80cbb3] I wish Flutter would allow creating a similar experience. The official iOS component library was in a really bad state the last time I checked :(
- [x_sebastianroehl#1e2358a3] Never noticed this before, but while going through my Google Search Console I saw that @HabitKit's website is actually generating some impressions 😲 Most clicks came from a direct "HabitKit" search. I’d love to shift that toward queries like "habit tracker" or "habit app". https
- [x_sebastianroehl#10d28a03] In-the-moment decision framework that's been working for me: "What would Cal Newport do?" Answers about 80% of my daily choices in under a second. https://t.co/9fR2l

- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=77, method=llm_persona_from_recent_content
- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=77, 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=77, 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=77, 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.
