Struck-through historical tasks (- [ ] ~~...~~) still read as open checkboxes to beacon's tooling — bullet status was picking one as "active" instead of the real next step. Marked all superseded Phase 3/5/T014/T019-21 entries [-] (deferred, per the project's own convention), and added a real Phase 8 with T-CUT-01..12 as trackable checkboxes matching atomic-cutover-plan.md, so tooling and humans see the same source of truth.
