Test 144

The metrics-router ownership review with Hema, Wes, and me is complete. Based on Wes's first-pass canary decisions, repeated safe owner-led-window work, maintenance of the tenant-bounded queue slice and diagnostics, the September rollout, and his operation of the October 6 Mosaic Commerce ramp, we decided to change the formal ownership record effective today. Wes is now metrics-router primary and I'm the backup. He owns routine metrics-router implementation, production operations, release and rollback decisions, and decisions to open owner-led windows under the existing deploy-pipeline, canary, health-return, stop, and rollback rules. I no longer need to make every fresh opening decision, though I may make one while covering for an unavailable Wes. I remain the architectural reviewer and escalation path only when a cross-service invariant, provenance, or failure-mode exception is triggered, rather than gating ordinary metrics-router windows. The accepted-batch diagnostic remains qualified for prospective production observation, but it does not retroactively establish whether any accepted batch was lost on October 6. The broader Mosaic scale-response cycle remains open, and no capacity-related production window is open or authorized. The Infra on-call roster is unchanged, and ingest-edge and shard-keeper ownership are unchanged. Shard-keeper remains outside Wes's solo scope unless I or the Cyrus-team backup explicitly pairs with him. Create a new metrics-router-specific Service identity and ownership runbook entry; update the existing Rotation handoff, metrics-router canary, and metrics-router on-call handoff runbooks; update the existing Mosaic capacity-response document and December 5 Metrics-router ownership review calendar event with this decision and the preserved boundaries; and post the concise bounded summary to the Infra Slack channel.
