      "title": "Reap an already-dead Unix child without signalling it",
      "body": "On Linux, `provably_gone` intentionally returns true for an exited but unreaped (`Z`) child. If the exit waiter is missing or suppressed—the stale-record condition this cleanup handles—this branch now skips `kill_pid_tree`, and the five-second fallback removes the `HostedSession` without collecting the child's exit status. Neither `PtySession` nor its underlying `std::process::Child` reaps on drop. Previously, `kill_pid_tree` reached `kill_pid`'s `waitpid(..., WNOHANG)`, which collected an already-dead child; the new path therefore leaves that zombie consuming a PID until the broker exits. Preserve a non-signalling reap, such as the existing `proc::reap_if_child`, when accepting dead-root cleanup.",

  "overall_correctness": "incorrect",
  "explanation": "Spec: one introduced Linux dead-child cleanup regression; otherwise birth capture precedes the waiter, Gate::AlreadyLive preserves that stamp, live tree-kill requires a positive match, and refusal reaches the error reply before de-table or resource drop, with no separate actionable standards finding. No decline-induced indirect kill was found: dead-root forced cleanup can close the owned ConPTY/Unix PTY and terminate the separately owned translation child, while the unchanged exit waiter at broker.rs:8471 independently calls PtySession::kill after wait (numeric SIGHUP through portable-pty on Unix, handle-bound TerminateProcess on Windows), a pre-existing risk not counted as patch-introduced. No formatters, builds, or tests were run as instructed; remaining runtime proof gaps are Linux unreaped-child recovery, full-broker mismatch/unreadable refusal with resources retained, and matching-root/dead-root end-to-end cleanup on Windows and Linux—the new injected helper tests alone do not exercise those ownership paths.",
