- test_code_kernel::TestModelFacingReset: reset stays in the schema under a stale
kernel_mode and a model-shaped reset call really discards kernel state (#96787).
- test_computer_use::TestStartupTimeoutPhaseDetail: cua-driver ready timeout names
the wedged phase + doctor hint, and the session stays un-started (#57025/#69372).
- test_file_operations::TestEscapeNativeToolArg (windows_only, was FAKE_OS): rg
search and the node --check linter get native C:/ paths, not /c/ (#84303).
- test_file_tools::TestSSHConfigWriteGate (2): a ~/.ssh/config write goes through
the real approval gate, BLOCKED with nobody present / in -q mode, nothing written (#93201).
- test_lazy_deps: a newer compatible plugin SDK is satisfied, never re-pinned down
(#98407, #86992); windows_only real Matrix probe reports unsupported.
- test_mcp_empty_error_message: empty/whitespace exception messages still yield a
diagnostic (#19417).
- test_mcp_stdio_children_dead: the fast-fail probe never calls the watcher on the
plain path, no un-awaited coroutine (#96044).
- test_subprocess_utf8_encoding: real _op_whoami survives invalid UTF-8 child output (#53428/#55339).
- test_tts_output_timestamp: same-second TTS calls get distinct output files (#43911).
- test_windows_agent_loop_papercuts::TestAutocompleteDevicePaths: a relpath
ValueError on a device path is skipped, not raised (#42016).
- test_windows_native_support::TestCronSchedulerBashResolution (2): cron .sh uses
bash from PATH; missing bash is an actionable error, not WinError 2.
