- signal_after_child_exit_takes_both_kill_fallbacks: a late signal (after the child exited) takes kill(-pgid) fail -> kill(pid) fail -> warn + return, with no panic — the reachable part of the REQ-TTY-02 fallback chain. - the remaining bridge error arms are documented-unreachable through the public path (per the review's disposition), with per-arm reasoning in the module doc: try_clone_reader (dup failure), reader read error (EIO -> EOF mapped), take_writer (second-take only), writer write/flush (externally-closed fd), waiter wait() (already-reaped child). The ADR-055 §4 -1 sentinel is covered at the adapter level (exit_error_sends_minus_one) — it also arises when the oneshot drops on kill-on-cancel. - local/pty.rs line coverage 80.85% -> 86.01%; total 94.48%.
