Replace the round-7 hardcoded `current_guest_function_ == 0x824F7800` gate with a runtime cvar `audit_jit_prolog_pc` (uint32, 0 = disabled). The cvar names the guest entry PC at which the x64 emitter inserts a CallNative to the prolog probe; the probe now dumps the active PC in each log line so multiple instrumentation campaigns can share output. Renames `audit_log_sub824F7800_args` (cvar) and `AuditLogSub824F7800Args` (host function) — the round-7 sub_824F7800-specific cvar and function are deleted, not left dormant. The `audit_handle_lifecycle` cvar and its existing AUDIT-HLC probe sites in xboxkrnl_threading.cc / kernel_state.cc are untouched. Validated by audit-059 round 9: with `--audit_jit_prolog_pc=0x821B55D8` the silph WorkerCtx-init chain entry fires 1× in canary at tid=6 lr=0x82172D8C (call site at sub_82172BA0+0x1E8 `bctrl`, the virtual dispatch through vtable slot 6 that statically-blind xref-walkers cannot enumerate).

Contributors Wanted!
Have some spare time, know advanced C++, and want to write an emulator? Contribute! There's a ton of work that needs to be done, a lot of which is wide open greenfield fun.
For general rules and guidelines please see CONTRIBUTING.md.
Fixes and optimizations are always welcome (please!), but in addition to that there are some major work areas still untouched:
- Help work through missing functionality/bugs in games
- Reduce the size of Xenia's huge log files
- Skilled with Linux? A strong contributor is needed to help with porting
See more projects good for contributors. It's a good idea to ask on Discord and check the issues page before beginning work on something.
