Round-14 of AUDIT-2BF (singleton-dump). Pairs with xenia-rs' --audit-mem-read-hex to emit one comparable XELOGKERNEL line resolving the bctrl target at sub_822F1AA8+0x90 (PC 0x822F1B4C): [0x828E1F08] -> singleton instance ptr [singleton+0] -> vtable [vtable+0] -> vtable[0] (= first virtual method, bctrl tgt) [vtable+24] -> vtable[24] (= slot 6, silph chain target) Two complementary hooks: 1. src/xenia/cpu/backend/x64/x64_emitter.cc: extend AuditLogJitPrologArgs. New cvar `audit_jit_prolog_mem_dump` (uint32). When non-zero and an `audit_jit_prolog_pc` fire happens, the host side dereferences the VA 3 levels deep and emits one AUDIT-MEM-READ line in the same format ours emits. Defensive per-level null + VA-range checks. 2. src/xenia/kernel/kernel_state.cc: one-shot dump in EmulateCPInterruptDPC of the same chain (hard-coded to 0x828E1F08). Useful when audit_jit_prolog_pc isn't set; fires the first time the CP interrupt path runs (after the singleton ctor has had time to populate). Read-only. Both gates default-off; no impact when cvars unset. ~65 LOC total across the two files. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
