Assessment 001 / Reproducible synthetic study
Show the failure.
Show the evidence.
Thirty fictional cases compare a rule-based toy simulator with a deterministic policy oracle. No customer system or real LLM was tested.
What this demonstrates
The toy omits stale-source checks, ambiguous-action handling and untrusted-document controls. Planted faults are not incidents in any third-party system.
The frozen oracle implements a fictional policy. Agreement tests fixture consistency only; it does not validate any real-world policy.

Engineering improvements to validate
Validate source versions, require fresh approval, deny instructions in documents as tool authority and reconcile ambiguous results before retrying. A real engagement tests these hypotheses against the authorized workflow and reports unknowns.
