Stewardship, Stale Stats, and the ADK Pipeline

Shadow-Mode Stewardship

The platform health stewards have been running in shadow mode, detecting anomalies without executing them. This approach allows us to evaluate the precondition selectivity of maintenance tasks before any enforcement. We are observing the system's behavior to ensure that the tool-executor rail—complete with grant checks, runtime approval evaluations, and coordination leases—remains the only sanctioned path for executing maintenance commands like VACUUM or ANALYZE.

Today, the stewards flagged several tables with stale planner statistics and bloated dead tuples. For instance, public.schedule_events had over 10,000 modifications since its last analyze, and public.table_catalog was showing 100% dead tuples. These are not immediate tasks for a human to fix by hand; they are observations recorded so we can refine the steward's logic. The correct disposition is to observe these conditions or close them if they clear on their own, ensuring we do not bypass the governance rails that prevent accidental locks on live tables.

Worker Resilience and Dead Letters

On the worker side, we encountered a dead-letter entry for the pie-correction-ingest job type. The job failed to fetch Discord insights replies via the Discord MCP tool, resulting in a fetch failed error after all attempts were exhausted. This is a dependency block rather than a transient glitch. The investigation revealed that the ingestion process relies on external service availability, and when that service is unreachable, the job lands in the dead-letter queue. We are keeping the fix narrowly scoped to this specific item, inspecting the runtime state before making any changes to the ingestion logic.

ADK Sample Agent Adoption

The ADK Sample Agent Adoption project has reached a significant milestone. We have successfully resolved the three outstanding operator backlog items: OB-130, OB-131, and OB-132. This means the durable audit sink is shipped, the Broadside review-time audit persistence is in place, and the prototypes remain read-only with approval-gated audit recording. The track has moved out of the waiting-decision state, and we are now using the shipped prototypes and review evidence to identify the next concrete adoption child OB.

The read-only prototype tools are fully implemented. The next step is to determine how to graduate these prototypes into durable sinks and the broader workflow. We are not merging or deploying yet; the main thread handles that. Instead, we are focusing on the mechanical routing fixes and the security review of the migration scripts to ensure the foundation is solid before we proceed to the next phase of the pipeline.

Verification and Next Steps

We verified the health of the blink-media-daemon, which was confirmed dead by the health watchdog. The steward proposed a restart, but no restart was executed, maintaining the shadow-mode discipline. We are continuing to monitor the dead-letter queue and the steward observations to ensure that our maintenance and worker resilience strategies are effective without introducing new risks. The focus remains on concrete, verified shipped work and the careful graduation of prototypes into production-ready flows.
