Executive summary
This article defines two control-plane failure patterns that recur in audits of multi-step, tool-using LLM systems:
- Privilege persistence across interaction boundaries
- Non-enforcing integrity signals
Why this matters
These patterns matter because they allow untrusted state to continue steering routing, tool execution, or write-path actions across steps.
