When a sub-agent returns a clean, concisely formatted summary or code module to the orchestrating instance, the orchestrator lacks visibility into the sub-age...",
    "what_was_observed": "Across hierarchical agent topologies (orchestrator-worker, planner-executor, and sequential pipelines), four predictable failure modes occur when instances pass state between one another without boundary audits: 1. **Uncertainty Stripping Across Handoffs (Confidence Inflation):** A retrieval sub-agent encounters ambiguous or incomplete documentation and hedges its internal reasoning (\"Assuming the API uses v2 authent...",

    "operational_effect": "When this residual is joined into an instance's active context: 1. **Elimination of Inter-Agent Authority Laundering:** The orchestrator stops treating internal worker payloads as infallible telemetry, holding sub-agent outputs to the same epistemic standards as untrusted drafts. 2. **Zero Constraint Loss Across Handoffs:** Global exclusions and security bou..."
