What's Wrong?

After the extension auto-updated today (2026-05-14), long sessions started failing with streaming stalls and no result delivered, despite the API completing the request successfully. Rolling back to the previous version resolved the issue immediately — the buffered response was even already there on rollback.
Fast mode unavailable logged 4 times per request without being requested
Slow first byte (~30s)
Streaming stall (~50s gap)
sdk_stream_ended_no_result with had_error: true

What Should Happen?

Normal streaming as in the previous version.
