Architecture has changed drastically (hexagonal refactor, web client
extraction). Every active plan has been reviewed, annotated with
'Completed' or 'Won't do' status, and moved to plans/done/.
Completed (7): gaps-and-improvements, liveness-drift, gated-execution,
nomos-code-review, codebase-cleanup, mascot-physics, backend-eval
Won't do (7): prometheus-lxc, control-room-webui, activity-gaps,
activity-timeline, frontend-os-apps, haos-capability-gaps, arr-audit
