+  Remote and human jobs are skipped with one log line. Status reliability
+  lives in an adapter field that gates the idle judgement.
+
+  A new section maps each rule to the code that enforces it and the test
+  that pins it, and lists the four rules that cannot be enforced in code.
+  Documentation shrinks to usage lines and table rows. The tests use the
+  real wrapper, subscriber, registry, publish script and watcher with real
+  process trees, and the 14-minute end-to-end scenario runs once.

+The watcher is a real `python -m lib_py.stall_watch` process against

+producer (`publish_event.py`); the broker is unreachable, so publish_event
+exits 2 after the record and events.log were written. herdr is the conftest
+mock, whose `pane process-info` answer has the shape of a real herdr 0.9.1

+(tests/fixtures/panes, S14). The agent process and its children are real
