Test 114

The Mosaic scope decision is complete. Hema approved a bounded metrics-router response, not a pipeline rewrite: keep the global queue capped at 2,048 batches, limit each tenant to 64 pending batches, and send additional work into the existing retryable backpressure path before acceptance. Wes owns implementation and load-test evidence; I own cross-service invariants and any future production-window opening decision; Cyrus and Roman own rollup-service capacity and parity evidence; Nadia owns queue and refusal alert semantics. Any stage must stop if queue-wait p99 exceeds 400 ms for five consecutive minutes, retryable queue-full responses exceed 0.5% for five consecutive minutes, any accepted batch is lost, or any consistency, parity, dropped-series, route, or full-health check leaves baseline. The formal service owner map is unchanged, Wes does not become metrics-router primary, Mosaic’s forecast ramp has not begun, and nothing is running in production yet. Update the September 3 Mosaic preparation brief into the final decision record, then post the bounded summary to #infra.

Mosaic Commerce confirmed that its new traffic shape will begin January 20 and is expected to reach 17.2 million data points per minute between 9:00 and 11:00 AM. With the January 8 staged replay qualified, create a “Mosaic Commerce capacity-observation window” for January 20 from 8:30 AM to 12:00 PM with Wes, Cyrus, Roman, Nadia, and me, and a “Mosaic Commerce capacity evidence review” for January 22 from 2:00 to 2:45 PM with those five plus Hema. Note that Wes will make the fresh opening decision as metrics-router primary only if the full health set is at baseline; Cyrus and Roman retain rollup-service capacity and parity evidence; Nadia retains queue and refusal alert semantics; and I cover only cross-service invariant and failure-mode exceptions. The review is to assess the prospective production evidence from January 20 before deciding whether the broader scale-response cycle can close. Preserve that the forecast is not observed traffic and that scheduling these events does not open or authorize a capacity-related production window before the January 20 checks.
