controller-status, ha-commit-engine, ha-heartbeat-committed-propagation,
ha-prevote, ha-single-leader-role, ha-wal-replication, libxce-failover, and
raft-ha-core-safety each had every numbered sub-task marked [x] but their
group-header lines (e.g. "1. Foundation: ...") left unchecked -- a cosmetic
gap, confirmed by roadmap.md's own IMPLEMENTED/VERIFIED notes and zero real
unchecked sub-tasks in any of the eight files. No task content changed.
