#5061 "Metric catalog belongs to what emits: plugins register their metrics; names match what is recorded". - The static METRIC_CATALOG is gone. metric_catalog() is core's own sources (the four monitor types and "steward", the app's open_fds/open_fds_pct, which were recorded but never offered) plus each loaded plugin's get_alert_metrics() export. A disabled plugin's sources leave the picker. - traefik offers what it records: error_rate_4xx_pct and error_rate_5xx_pct. The old "error_rate" was never recorded, so a rule on it could not fire. - tests/core/test_metric_catalog.py walks every MetricBatch.add / record_metric call (traefik's tuple loop included) and fails on a recorded metric the catalog lacks; it shows on a synthetic writer that it can fail.
