axpbox

Port upstream ES40-Emu commits into axpbox. Use whenever the user asks to bring in, sync, or port changes from the es40 repo (github ES40-Emu/es40, local clone to /tmp/es40). Covers delta computation, wholesale-replace vs manual patching, the axpbox invariants (std:: threading, .hpp, clang-format, rebrand), and the verification gates.

Boot OpenVMS from the disk image in test/run-axpbox to verify end-to-end guest operation (SRM boot command, bootstrap, SYSINIT, startup to login). Use for deep verification after CPU/disk/timing changes.

Run the headless SRM firmware boot test (boots to P00>>> over telnet and diffs the console log). Use after any change to CPU, chipset, serial, or firmware code, and always once per verified stage of larger work.

Boot the ARC/AlphaBIOS console from a pre-programmed flash image with the S3 Trio64 on the SDL window. Use to verify the ARC/Windows-NT path (flash boot, nvram auto-arc script, S3 graphics).

Visually verify the S3/VGA/SDL render pipeline (framebuffer dumps, SRM-on-VGA text check) and test mouse/keyboard input paths. Use after graphics, GUI, S3, or input changes, or when a guest's VGA output needs inspection on a headless/WSLg host.
