## Reach
- followers: 96317
- posts_observed: 5
- verified: false
- size_tier: koc

## Engagement
- status: average_measured
- engagement_rate: 0.01289
- engagement_rate_basis: average_of_observed_posts
- avg_interactions_per_post: 1242
- measurement_source: cn_posts_max
- measurement_formula: likes + comments + shares (douyin) or likes + comments + collects (xiaohongshu), max over observed posts
- comparable_pool: peak_interactions
- status_note: engagement_rate is a MEAN over the posts we observed (posts_in_average says how many).
- 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.

## Audience (inferred)
- status: present
- description: field surveyors and instrument users in surveying engineering, construction, and pipeline detection
- roles: none
- seniority: practitioner
- pain_points: traditional surveying equipment is cumbersome to operate and limits single-person efficiency, difficult to collect accurate data in irregular structures or obstructed environments, pipeline detection and coordinate measurement require multiple steps, time-consuming and labor-intensive, high risk and cost when measuring in complex or hazardous terrains
- posts_analysed: 40
- confidence: 0.75

## Commercial (inferred)
- audience_buyer_fit: 0.8
- promotion_intent: 0.7
- open_to_collaboration: false
- contact: Koinon does not publish creator contact details.

## Quality signals
- authenticity_score: 58
- authenticity_basis: engagement_observed
- credibility_score: 57
- 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.

- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=89, 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=68, method=Starts at 60; interactions-per-follower on collected posts then adds or subtracts (large following with near-zero engagement is penalised heavily). — The input set differs by platform; do not compare this score across platforms.
