-  transient family dispatches .typed_instance to ITransient*, native
-  transients answer interop method calls (TRANSIENT_METHOD_MAP), and
-  the O-045 reduce-fusion gate no longer realizes the head to decide

-  gate is REMOVED and green on the 3-vCPU macOS runner. D-559 = the peer-STW

-  park honors `fabrication_depth` (JVM-GCLocker shape); park/enterBlocked
-  asserts; `safepoint.max_stopworld_wait_ns`; guard `alloc-agent/nested_xagent`.
