  "message": "[Async] Fix macOS CTS test flakes: dangling stack ops, RST detection, kqueue event loss (#23570)\n\nTurns out, macOS has some... quirks.\n\nThree categories of fixes for macOS socket CTS test failures:\n\nproactor.c: Track `any_operation_removed` through\nprocess_operation_chain to skip event_set_modify when the fd chain is\nunchanged after multishot MORE continuations. On macOS kqueue, redundant\nEV_ADD resets the knote\u0027s pending state, causing level-triggered events\nto be missed until a new state transition occurs.\n\nmultishot_test.cc: Fix dangling stack-local operation pointers in all\nfour multishot tests. Operations submitted inside loops (connect_op,\nsend_op) now wait for their specific completion tracker instead of\nrelying on PollUntil returning on any completion. All tests also gain a\nsafety DrainPending() when the cancel-wait timeout expires without the\nmultishot terminating, preventing TearDown from processing operations\nagainst destroyed stack memory.\n\nerror_propagation_test.cc + socket_test_base.h: Add ReleaseWithRst()\nhelper that closes a socket with SO_LINGER(0,0) (forcing RST instead of\nFIN) and submits a recv probe on the peer to detect the RST and set\nsticky failure deterministically. Four error propagation tests converted\nfrom non-deterministic send-until-fail loops to single deterministic\nassertions. MultishotRecvPeerCloseDeliversFinalCallback fixed with the\nsame release+poll-until-final+safety-cancel pattern as multishot tests.\n\nCo-authored-by: Claude \u003cnoreply@anthropic.com\u003e",
