There was a problem hiding this comment.
Blocking: POST /api/admin/backfill is exposed on the public API with no auth, rate limit, or mutual exclusion. Any caller who can reach the service can trigger an expensive background crawl repeatedly, and concurrent requests will start overlapping backfills against ScrapingBee and the DB. Given the credit cost and runtime, this needs at least an admin secret or auth gate plus a single-flight guard before it is safe to ship.

Add RunBackfill() to CronService: same upsert logic as RunCrawlNow but with deeper page depths (newest=25, magic=15, end_date=10 by default, all overridable via BACKFILL_DEPTH_* env vars). Expose via POST /api/admin/backfill; runs async and returns 202 immediately.
