Abstract: Policy-governed agents must interpret case evidence while following an authorized procedure. We present \textsc{Stage}, an executable-graph framework that confines model judgment to policy-scoped nodes while placing procedural control in deterministic code. At each node, the model receives task-relevant policy context and returns a typed result, while the coordinator enforces the reviewed execution contract. We evaluate \textsc{Stage} on SOP-Bench Referral Abuse, two $\tau^2$-bench domains, and Smart Dispute, a proprietary banking benchmark. Compared with monolithic full-policy execution, \textsc{Stage} generally improves task success and repeated-run reliability across workflows of varying procedural complexity. The largest gains occur on the deeper Telecom and Smart Dispute workflows, where $\mathrm{Pass}^3$ increases by 7.5–55.0 and 57.2–65.7 percentage points, respectively, depending on the model. These results show that combining policy-scoped context with deterministic procedural control can improve the reliability of policy execution.
