    On 2026-03-10, Writer Agent experienced a SEV1 full outage driven by database lock contention during deployment. An in-band schema migration waited on long-lived idle-in-transaction sessions, causing query queueing on core.threads and rapid connection pool exhaustion across pods. Service recovered after terminating blocking sessions and stabilizing rollout; follow-up actions are in progress to harden migration safety and transaction lifecycle controls.
