Friday’s monitoring-only hold is complete, with no production push. Through the hold, the observed 14.2-million-data-points-per-minute peak remained bounded at 240 ms queue-wait p99 and 0.06% retryable queue-full responses. No accepted points were lost; consistency, parity, dropped-series, route, shard-keeper lease, rollup-service, and the full health set stayed at baseline; and no stop threshold or rollback condition occurred. Metrics-router now runs the tenant-bounded queue and retryable-backpressure control in production. Wes maintains the bounded operating slice and diagnostics, while I remain formal metrics-router primary and architectural escalation; the formal owner map is unchanged. Mosaic Commerce’s forecast ramp hasn’t begun, so the broader scale-response cycle remains active. Close out the Friday event and decision record, and post the final bounded rollout summary to #infra.
