Stewardship and Trace Completeness

Today’s build focused on closing the gap between prototype adoption and durable system health. The ADK Sample Agent Adoption track has moved out of the waiting_decision state after resolving the three core operator backlog items that were holding it back. The durable audit sink is now shipped, Broadside review-time audit persistence is live, and the prototypes remain read-only with approval-gated audit recording. This clears the path for identifying the next concrete adoption child without standing decision blockers.

On the platform health side, the steward system flagged a confirmed-dead service, blink-media-daemon, after three consecutive failed checks. The watchdog proposed a restart, but the action remains recommend-only. Simultaneously, the JobFoundry dead-letter queue for kg-fact-adjudicate cleared itself as the handler success rate recovered above the 0.8 threshold. The steward action to clear obsolete dead-letters is now eligible, demonstrating that the recovery tier logic is functioning as intended.

However, the memoir prompt delivery lane remains stalled. The aria-ghostwriter has not posted a message within the 168-hour SLO lookback for the monitored lane. The steward has proposed investigating scoped delivery for the source and category, checking the producer, desk-delivery, and gateway permissions. This is a critical path item because it blocks the delivery of explicitly monitored content.

In parallel, the LLM Trace Completeness Backfill project continues to bridge legacy AI/LLM processor calls into Nexus and Langfuse provenance. The focus remains on handlers with high missing-trace counts while keeping raw private content out of logs. The mechanical routing fixes in the Nexus monorepo are being reviewed by an adversarial subagent that defaults to finding defects rather than blessing changes. This read-only review process ensures that the trace bridging does not introduce new vulnerabilities or data leaks.

The tradeoff here is clear: we are prioritizing trace completeness and auditability over immediate feature velocity. By keeping the ADK prototypes read-only and requiring approval-gated audit recording, we ensure that the system remains observable and reversible. The dead-letter queue recovery confirms that the resilience patterns are working, but the stalled memoir delivery reminds us that automated health checks are only as good as the underlying delivery mechanisms.

Next steps involve verifying the memoir delivery lane fix and promoting the ADK prototypes into durable sinks once the operator backlog is fully resolved. The trace backfill will continue to run in the background, ensuring that legacy calls are properly attributed without exposing sensitive data.
