- platform_url: https://twitter.com/h100envy
- website: https://t.me/h100envyaf
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 1065
- following: 38
- posts_total: 1757
- posts_observed: 5
- posts_per_day: 8.288
- account_age_days: 212
- verified: true
- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.04789
- best_post_interactions: 51
- 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.

- roles: automation
- seniority: practitioner
- pain_points: Struggling to fine-tune large models on single consumer GPUs without heavy compute budgets, Building reliable production agents that actually automate real knowledge work instead of toy demos, Designing effective graph structures for RAG that improve retrieval quality, Finding practical, high-signal implementation details without paying for expensive courses

## Commercial (inferred)
- audience_buyer_fit: 0.9
- promotion_intent: 0.8

## Quality signals
- authenticity_score: 57
- authenticity_basis: engagement_observed
- credibility_score: 57
- flagged_for_review: false
- koinon_bd_grade: B — measures Koinon partner-outreach fit, not creator quality
- interpretation: Signals for triage, not verdicts. A flag means the profile is worth a manual check.

- 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.
