回應欄位

YouTube Video Post (normalized)

Normalized YouTube video. Provider-private fields MUST NOT appear. Metric names are frozen (views/likes/comments — 观播放/赞/评); hidden counts normalize to 0. `title` is the platform extension field (the video headline — text carries the description). author and created_at are nullable: search/list cards may omit the channel block and the web surface sometimes ships only relative publish-time text ("2 weeks ago" — lossy, never fabricated into an instant; a present-but-unparsable timestamp still fails).
