Those plan-specific hosts were missed by an exact host check, so dozens of tools that should stay deferred were inlined on every turn. Live measurement showed a forty-tool…
Second, latency. Pull request 4607 stops buffering a stream unless the compression marker is new this turn. Previously, once a marker entered history, every later turn took the buffered path, so clients got nothing until generation finished — over seventy percent of Opus turns in one report. Pull request 4606 skips…
