  "description": "The single JSON object the Sentinel Gate emits for one regulated-decision case. The gate decides ESCALATE (route to a human) vs DECIDE (safe to automate). When action=ESCALATE, escalation_category is one of six ids and a category-specific block is present; when action=DECIDE, escalation_category is null. Prompt version sentinel_sys_v1. Note: additionalProperties is intentionally true because the category-specific block key varies by category (policy_violations, missing_preconditions, boundary_analysis, confidence_factors, conflicting_signals, external_dependency) and DECIDE cases carry decision/rationale keys.",
