What the crawler records
The daily workflow refreshes public GitHub candidates, verifies repository metadata, records score and rank history, and rebuilds daily skill picks. This keeps the site from relying on one-time scraped rows.
Verification stores repository stars, forks, language, topics, license, recent push date, and the timestamp of the verification pass. Non-GitHub provider pages are not forced into repository metrics.
Trend charts use recorded history only. When a model has one snapshot, SkillRank shows the current snapshot instead of fabricating a seven-day curve.
