The system.* family (1 verb). Every verb enters through the one front door: it is capability-checked, permission-checked, scope-checked and audited before it runs (see Security & permissions). Each entry below lists its capability, risk class (which fixes the minimum autonomy level), the minimum caller permission, its availability tier, whether it is idempotent, and any outbound egress.
