Fixed the boot (fr this time) the whole laptop reset thing turned out to be two bugs stacked on each other: the bootloader was trusting/rejecting BIOS geometry based on vibes, and the kernel entry point was jumping into a debug helper instead of _start, so the CPU executed one stray ret into the void and triple-faulted. coil now makes the BIOS prove its geometry against a build-time checksum before trusting it, and checksums the whole kernel before jumping in. Boot output is an actual diagnostic language now: gk = geometry truthful, gf = BIOS lied, C! = wrong bytes arrived, and nothing resets silently anymore. QEMU boots all the way to BASIC, audio included. Also cleaned up helix.c (boot debug spam now only speaks when something’s actually wrong, RIP “HELIX FAILIURE” typo), evicted BTBX from the prompt, it’s js => now, and am working the BASIC interpreter with a bit of a rewrite: dispatcher no longer depends on include order and prayer, dead duplicate file-I/O code confirmed gone, graphics.inc brace damage found and fixed. Laptop test tomorrow-ish, then the interpreter cleanup lands. see u next time!
