## Identity
- platform: x
- handle: shin08021888
- platform_url: https://twitter.com/shin08021888
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 1187
- following: 1619
- posts_total: 5063
- posts_observed: 2
- posts_per_day: 1.94
- account_age_days: 2610

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00253
- best_post_interactions: 3
- 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.
