On each AUDIT-PC-PROBE fire, treat gpr[reg] as a base object, dump its
first 64 bytes, follow [base+off] to a sub-object, dump that, then follow
[[base+off]+0] to its vtable and dump 48 slots. Env-gated
(XENIA_AUDIT_DEREF=<reg>:<off>), read-only, lockstep digest unaffected.
Captures the live work-item + stream object + vtable at sub_824510E0
before the pool recycles the slot — which overturned the prior session's
"infinite spin" diagnosis: the streaming read PROGRESSES 68/68 128KB
chunks of a 9MB file, then the hub (tid=5) blocks INFINITE on a
self-created Event/Manual (0x1060) that is never signaled.
