Live trace (BT_MECH_LOG) on the pod TEST.EGG mech: '[mech] segment walk done: subsystemCount=33 weaponCount=7' -- the segment walk instantiates the ENTIRE real subsystem roster (31 subsystems + 2 sentinels, 7 weapons) from the actual streamed model, no crash. The structural reconstruction is proven end-to-end on real data. The crash is AFTER full construction, in MakeAndLinkViewpointEntity's attribute- watcher setup (an AttributeWatcher resolving a subsystem attribute via GetAttributePointer). Phase-5 frontier confirmed = per-subsystem AttributeIndex tables + watcher wiring. Trace gated behind BT_MECH_LOG. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
