- website: http://instagram.com/ai.caffe1ne/
- country: South Korea
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 1084
- following: 166
- posts_total: 223
- posts_observed: 1
- posts_per_day: 0.369
- account_age_days: 605
- verified: true
- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.06734
- best_post_interactions: 73
- 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_ai_caffeine#3542f553] ☕️ 캐시 (Cache)에서 제일 무서운 건 적중하지 않은 게 아니라, 마침 동시에 만료되는 순간임. 캐시가 꺼진 직후 요청 1,000개가 한꺼번에 들어오면? DB (데이터 베이스)나 외부 API로 1,000번의 요청이 동시에 꽂힘. 서비스를 죽이는 건 트래픽이 아니라 `캐시 쇄도 현상(Cache Stampede)`일 수 있음. 🤯 GitHub 1.3k Star `Sturdyc`는 이걸 막아주는 Go 캐시 라이브러리. 같은 Key를 동시에 요청해도 실제 원본 데이터를 조회하는 건 단 한 번. 나 (https://twitter.com/AI_Caffeine/status/2064262292791767157)
- [x_ai_caffeine#f5d3e379] ☕️ Codex 쓰면서 Max (최대 추론 강도) 안 보인다고 포기하지 마셈. 들리는 얘기로는 `Luna + Max`가 `Sol + Medium`급 체감인데, 비용은 대략 1/5~1/6 수준이라고 함. 👀 문제는 `Max`가 기본으로 숨겨져 있어서 모델 선택창에 바로 안 뜬다는 것. 설정에서: 구성 → 모델 기능 → 사용 가능한 추론 수준 → 최대 선택 한 번 켜두면 Luna·Terra·Sol 모두 최대 추론 강도를 선택할 수 있음. Token 절감이 실제로 얼마나 되는지는 작업마다 다르겠지만,

## 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=20, method=llm_persona_from_recent_content
- audience.roles: source_type=ai_inferred, confidence=0.4, freshness_days=20, method=llm_persona_from_recent_content
- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=20, 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=111, 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=111, 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=111, method=platform_profile
