    Hi, I reviewed 'Android WebSocket failure' and can start immediately. I can deliver a first usable version quickly and iterate based on your feedback. If this scope still matches your priority, I can proceed right away.

    Closing in favor of #132031, which tracks the original SendAsync_Cancel_Success / Actual Open failure with a specific matcher. I removed the broad KBE classification because it matched every failure in the Android WebSockets test assembly, including connect-cancellation failures covered by #130439 and unrelated work-item failures. Distinct Android failures should surface and be tracked separately.
