Use when ConfigHub's Unit Data and the cluster's live state for that Unit have diverged — phrases like "reconcile drift", "the cluster changed out of band", "someone kubectl edit'd this", "ConfigHub and the cluster disagree", "accept the live changes", "overwrite the cluster with ConfigHub", "refresh from live", "who owns this drift?", "we have drift on app-a in prod". Runs `cub unit refresh` to pull current live state, `cub unit diff` against Data, walks the decide-who-wins decision (ConfigHub wins → re-apply; cluster wins → absorb; merge → selective reconcile), and executes the chosen path. Do not load for revision history rewind (use `rollback-revision`), for post-apply verification / three-way agreement checks (use `verify-apply`), for the first-time apply of a newly-bound Unit (use `cub-apply`), or for importing wholesale live resources into a brand-new Unit (use `import-from-cluster`).
