+All four extension points are now registries — the modules are closed
+for modification, open for extension:
+- gates: BaseGate + register_gate + GateContext; evaluate() runs every
+  registered gate. New: ConformanceGate (frozen fixtures or no pass)
+  and RegressionGate (flag-only vs registry best-known).
+- stage types: register_stage_type() (KNOWN_STAGES is a live alias).
+- corpus source kinds: schema data + planner volume-provider registry.
+- license policy: LicensePolicy objects (allow_waivers), never edits.
