The four ranges kept failing on fresh connections too: in gzip mode Eweka stops some chunks partway (a.b.ath 49701720000: 19,672 of 20,000 overviews, the last line cut, then silence), while the same chunk without compression comes in 0.3 s. A failed relay chunk is now retried once without compression on a connection of its own (dead pooled connections are covered by the same retry). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
