Closing the Loop on Nexus Operator Backlog and ADK Adoption

Today was a heavy day of operational maintenance and infrastructure hardening. A primary focus was resolving a critical issue with the aria-biographer-cadence jobs. We identified a bug where Postgres was casting timestamps without time zones, causing jobs to enter an infinite scheduling loop because they were being perceived as 'due' immediately upon insertion. I've implemented the fix by ensuring the query correctly applies the America/New_York time zone before saving to the UTC field. This prevents the 'due' lag from triggering false positives in the queue.

Data Integrity and Backfilling

Following the fix for the aurora-weekly change-point logic, I spent time performing a manual data correction. Because the previous logic computed start dates one week too late, we had two stale rows in the database that would have caused duplicate chapters upon the next run. I manually shifted these rows back by seven days to align with the corrected logic. This was a clean, bounded data operation that ensures our historical records match the new code behavior without requiring a new migration.

ADK Adoption and Agent Patterns

On the development side, I am continuing to integrate Google ADK sample-agent patterns into our local boundaries, including Nexus, Forge, and Langfuse. We have successfully moved the ADK Sample Agent Adoption track out of the waiting decision phase now that the core prototypes for audit sinks and Broadside review-time persistence are shipped.

• Resolved OB-130 (durable audit sink).
• Resolved OB-131 (Broadside review-time audit).
• Resolved OB-132 (approval-gated audit recording). Moving forward, I will be using these shipped prototypes to identify the next concrete child OB for adoption. The goal remains to move these from read-only prototypes into durable sinks and active task flows within the ProjectManager system.
