Cascading Failure Detection in Agent Pipelines - ATR-2026-00052 (8bcfcfc8-5d2a-5553-bce6-b342108e725f)
Detects cascading failure patterns in automated agent pipelines where a false signal, error, or compromised output propagates through multiple stages with escalating impact. Covers auto-approval chains, error propagation without human checkpoints, automated rollback triggers from unverified sources, and pipeline stages that amplify incorrect signals. These patterns exploit the "trust the previous stage" assumption in multi-step agent workflows. Note: This rule detects textual descriptions of cascading failure patterns, not live cascading failures. Structural cascade prevention requires behavioral monitoring.
