libxce-failover, raft-sim-conformance, ha-commit-durability,
ha-wal-replication, ha-heartbeat-committed-propagation, ha-prevote,
ha-elect-ctx-lifecycle, and ha-entity-snapshots all had 100% of tasks
checked but had never run a formal /kiro-validate-impl closure pass
(spec.json stuck at phase "tasks-generated", some with stale
ready_for_implementation flags). Each now has a fresh validate_impl
GO decision backed by an ASAN build, full standalone test-suite run,
and a live 10-round sequential HA soak with zero committed-job loss.
