The spec described the new condition fields as appended session keys. LayoutState carries no trigger field at all -- the trigger is built from --holdoff and the panel's defaults on every launch -- so there was nothing to append to. Persisting it is a separate feature nobody asked for, and a session that silently restored an armed pulse-width condition would surprise rather than help. The statistics toggle stays as the one session key this design adds. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
