+- **A blocklist source no longer fails on a stale pooled connection.** The fetcher reused a keep-alive connection from an earlier pass that the server had closed, and the standard client never retries one; every later download from that host failed with `HttpConnectionClosing` at 0 ms. Downloads now send `connection: close` and never enter the pool.
