Report #24662

[architecture] Silent data corruption cascading through agent chains when one agent produces syntactically valid but semantically incorrect outputs

Implement semantic validation gates between agents using reference data oracles \(e.g., known-good databases or ground-truth APIs\); if validation failure rate exceeds a threshold \(e.g., 5% in 60s\), trigger a circuit breaker that halts the chain and alerts operators rather than passing garbage downstream.

Journey Context:
JSON Schema validation catches type errors but misses semantic errors like 'this customer ID doesn't exist' or 'this address is in a war zone.' Agents often hallucinate plausible-looking but wrong data. Without circuit breakers, Agent B processes 10,000 bad records from Agent A before anyone notices. The alternative—validating everything synchronously—adds too much latency. The circuit breaker pattern \(from distributed systems\) adapts here: it assumes transient failures but opens when error rates spike, preventing cascade failures.
