One bounded batch uses the existing technology detector with a fresh fetch per domain. Reports additions, removals and version changes only when a caller supplies a previous snapshot. First scans have changes=null. Root HTTPS URLs only. Caller snapshots are not authenticated historical evidence. No background jobs, shared history, callbacks or inferred installation dates. Fixed price for a batch of one to three domains.
