Report #73521

[architecture] Agent consumes malformed output from upstream agent causing cascade failures

Enforce strict JSON Schema validation at agent boundaries with rejection/retry loops; treat validation failures as hard stops that trigger dead-letter queues, not exceptions to catch internally

Journey Context:
Defensive coding inside agents is insufficient; boundary validation is the architecture-level fix. Tradeoff: added latency \(5-20ms\) vs. preventing error propagation. Alternative of implicit trust leads to silent data corruption. Schema must be versioned and enforced before any business logic execution.
