-
-The delta-API path always runs **full extraction** (the feed is an explicit "this changed"
-signal) and only enriches packages that are `is_critical` in `packages_universe`; non-critical
-purls in the feed are dropped.
-
 **Concurrency guidance:** Maven Central handles 10–15 concurrent requests per IP without throttling. Retry logic with exponential backoff handles 429/403s. Keep `POM_FETCHER_CONCURRENCY` ≤ 5 locally — repeated local runs heat the IP (see [Known Exceptions](#maven-central-403-rate-limiting)).
