5 Myths Backend Engineers Believe About Per-Tenant AI Agent Schema Versioning That Are Silently Breaking Long-Running Agentic Workflows Across Foundation Model Upgrades in 2026

It starts as a quiet anomaly. A tenant's long-running agentic workflow, one that had been reliably orchestrating document processing, tool calls, and memory retrieval for weeks, suddenly starts producing malformed outputs. No deployment happened. No configuration changed. The only thing that shifted was a silent foundation model upgrade
