- test_cron_bot_chat_delivery::test_deliver_failure_banner_only_stdout_names_exit_code_not_banner:
a banner-only failed delivery records the exit code, not the resume banner (#104056).
- test_cron_script::TestScriptTimeoutTreeKill (3): pid 0 never reaches
kill_process_tree (os.kill(0) would kill the scheduler's own group); a
tree-kill that signals nothing still falls back to group termination; an
already-exited script is never signalled (pid reuse).
- test_oneshot_guard_warning::test_guard_warns_on_rearmed_consumed_record:
removal of a re-armed consumed one-shot logs a WARNING naming `cron resume` (#93524).
- test_hermes_state_conn_lock_audit: repo-wide AST lint, every self._conn call
outside construction holds self._lock (SIGSEGV race with close(), #99349).
- test_pattern_b_scaling::test_statement_count_does_not_scale_with_sessions:
list_sessions_rich SQL count stays within the N+1 budget (#95380); repaired to
trace pooled read connections and fail if the trace sees nothing.
