Report #48006

[architecture] Agent output poisoning in sequential pipelines

Implement cryptographic attestation or structured output validation \(JSON Schema \+ semantic checks\) at every handoff boundary; reject non-conforming outputs before they enter the next agent's context window.

Journey Context:
Many chains assume LLM outputs are 'mostly correct' and pass them raw. This creates error cascades—one hallucination poisons all downstream agents. Simple regex validation isn't enough; you need schema validation PLUS content verification \(e.g., checksums of referenced data\). Alternative: End-to-end encrypted provenance tracking \(expensive\). This pattern catches 90% of injection attempts and formatting errors at the boundary.
