Summary
Fixes #2290
Release event-loop handles in
ProviderProcessSupervisorwhen process group stop reports incomplete cleanup, and close cooperative protocolstdin, detach listeners, and reset internal state inJavaScriptAnalysisWorker.#stop. This ensures that when process inspection fails closed under restrictive environments (such as denied/bin/psprocess table access), the public CLI completes boundedly rather than hanging alive indefinitely while keeping cleanup uncertainty and retained resources intact.Problem and expected behavior
Under restrictive sandbox policies where process inspection is rejected (e.g. setuid
/bin/psfailing withspawn EPERM),cleanupOwnedProcessGroupfails closed and reports{ cleaned: false, reason: "process table could not be inspected: spawn EPERM" }. REA correctly preserves honest uncertainty and emitscleanup_incomplete.However:
JavaScriptAnalysisWorker.#stopnever closed cooperative protocolstdin(supervisor.launch.process.stdin?.end()), leaving the worker processjavascriptAnalysisWorkerProcess.jsalive indefinitely awaiting requests onprocess.stdin.ProviderProcessSupervisordid not unreference the child process or its stdio stream handles (stdin,stdout,stderr) when#stopWithinreturnedincomplete.JavaScriptAnalysisWorker.#stop,stopped.status === "incomplete"returned before detaching thestdoutdata listener or resetting worker state.Because active process handles and open stdio pipes remained referenced in Node's libuv event loop, the public CLI remained alive for minutes after outputting the
cleanup_incompleteerror report.Expected behavior: the CLI completes within a bounded lifecycle after reporting
cleanup_incomplete, without signaling unverified process groups or discarding retained ownership records.Change and scope
