This loses watcher service config and cinder notification driver on the controller.\n\n**Severity**: HIGH | **Confidence**: 0.9\n\n**Risk**: The watcher-grenade-multinode job runs without watcher controller config (migration_max_retries, migration_interval, api_version) and cinder notification driver. Grenade upgrade tests may fail or produce unreliable results with missing/default config values.\n\n**Priority**: Before merge\n**Why This Matters**: The old watcher-grenade job had post-config for $WATCHER_CONF and $CINDER_CONF. The new job loses this because YAML merge keys do not deep-merge nested dicts. Subnode group-vars include *watcher_conf_base but the controller\u0027s post-config is silently dropped.\n\n**Recommendation**:\nExplicitly add the missing post-config to the watcher-grenade-multinode job vars. Either (a) add a devstack_local_conf.post-config section alongside the inherited test-config, or (b) define a new anchor that combines both post-config and test-config and use it directly.
