src/debug/vjdebug.c implements struct vj_debug_iface: side-effect-free peek (JaguarReadByte DEBUGGER), policy-checked poke, both RISC register banks, RISC disassembly, attach/halt-pump/breakpoints on the existing GDB halt machinery (a host can attach without a socket; GDBHalt pumps it and never blocks when nothing could resume it), a one-walk OP display-list snapshot taken before the OP rewrites HEIGHT/DATA, a blitter launch log ring, TexReplaceReload, and the frame counter. The interface is handed over once via VJ_ENV_SET_DEBUG_IFACE, only to a frontend that set VJ_CAP_DEBUG (RetroArch never does). Detached cost: one global test per OPProcessList call and one per blitter launch. Statics reset on unload and deinit. test/test_debug_iface.c drives it on yarc.j64: who gets the interface, peek == jaguarMainRAM, the poke policy, halt/step/continue/detach through a scripted host, breakpoint re-hit, OP snapshot, blit log, and an identical frame + RAM hash with everything switched on.
