## Reach
- posts_observed: 1
- verified: false
- size_tier: nano

## Engagement
- status: not_measurable_on_platform
- status_note: This platform publishes no follower count, so an engagement RATE has no denominator here. No amount of further collection can produce one — it is a property of the platform, not a gap in our data.
- 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.

## Content
- category: entertainment
- subcategory: news_media
- category_confidence: 0.8
- category_source: derived_from_recent_content
- topics: 创意疲劳诊断, 广告表现优化, 代理商沟通问题
- bio: Your top ad has been running for 6 months. Performance dropped 40% in the last 2 months. Your agency says: "The algorithm changed." Wrong. Creative fatigue. **What Creative Fatigue Looks Like:** → Hook rate dropping (fewer people stop scrolling) → CTR declining over time → CPC increasing → Same mess

## Audience (inferred)
- status: present
- description: Advertising practitioners, mainly small and medium-sized advertisers, agency teams, and frontline ad optimization executors
- roles: ads
- seniority: practitioner
- pain_points: Long-running ads gradually underperform without clear root causes, Agencies blame algorithm changes instead of creative fatigue, Lack concrete methods to identify and address creative fatigue
- posts_analysed: 1
- confidence: 0.4

## Commercial (inferred)
- audience_buyer_fit: 0.9
- promotion_intent: 0.8
- open_to_collaboration: false
- contact: Koinon does not publish creator contact details.

## Quality signals
- authenticity_score: 60
- authenticity_basis: platform_default
- flagged_for_review: false
- koinon_bd_grade: A — measures Koinon partner-outreach fit, not creator quality
- interpretation: Signals for triage, not verdicts. A flag means the profile is worth a manual check.

Creative fatigue. **What Creative Fatigue Looks Like:** → Hook rate dropping (fewer people stop scrolling) → CTR declining over time → CPC in (https://www.linkedin.com/posts/stemazzei_your-top-ad-has-been-running-for-6-months-activity-7439385427897257984-0bxy)

## 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=76, method=llm_persona_from_recent_content
- audience.roles: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=76, 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=76, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=116, 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=0.25, freshness_days=76, method=Fixed value 60. This platform exposes no public follower count, so no authenticity heuristic is run at all. The number is a placeholder, not a measurement. — 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=116, method=llm_partner_fit_classifier + fit_score >= 0.5 => A; >= 0.35 => B; else C. authenticity is not an input. — Koinon partner-outreach fit, not creator quality.
