KateRTX · full project · SPV + ELF · zero host install
======================================================
Path: Desktop/x/KateRTX
No symlinks. No ~/.config install. Build stays here.

WHAT IT IS
  SPV land     · spvs/*.js plugs · js/ · compute .comp
  Not-only-SPV · ELF binaries: krtx-engine · krtx-term
  Kate         · project-local config via XDG inside KateRTX/.config

SPV LOADER / RUNNER · ONE LULZ
  bin/krtx-spv   ·  bin/krtx   ·  ELF loads+runs plugs
  list | in <id> | engine | one/lulz | law
  JS plugs → out/run_<id>.html self-runner
  compute .comp → krtx-engine hotswap folder

FIRST TEST
  ./build.sh
  ./bin/kate-rtx test
  ./bin/krtx one           # ONE LULZ
  ./bin/krtx-spv list
  ./bin/krtx-spv in grin
  ./bin/launch-rtx         # fullscreen compute
  ./bin/launch-term        # classic term ELF

BUILD (zero cost · gcc + optional glslang)
  ./build.sh

KATE (isolated · not system install)
  ./bin/kate-rtx kate

CLI
  ./bin/kate-rtx help|build|engine|term|launch|compile|status|test

LAW
  LINEAR single · no duo
  BGS ground → BGF measure · SPV rides BGF · free never folds
  AMOURANTHRTX learned · raymarch · compute · SPV sacrifice honored
  GRIN free=1 · miniglider scrollbar in Kate is still awesome

LAYOUT
  bin/krtx-engine   ELF fullscreen
  bin/krtx-term     ELF SPV terminal
  bin/launch-*      launchers
  spvs/             JS SPV plugs (owned copies)
  engine/           engine.c · shaders · spvs compute
  src/krtx_term.c   term source
  kate/             project-local kate assets
  .config/          created only when you run kate-rtx kate

MAIL (Claws · Santa theme · Titan)
  ~/Projects/Santa/bin/claws-santa     # RWG theme + SSL pins · distro claws
  SECURITY: Projects/Santa/SECURITY.txt
  SPV: krtx-spv in santa · native optional: Projects/Santa/bin/santa
  Titan SSL 993/465 · no krtx-mail binary · no 127 agent required

GROK API (ELF)
  ./build.sh                           # builds bin/krtx-grok
  ./bin/krtx-grok status
  ./bin/krtx-grok "hello"
  key: export XAI_API_KEY=…  or  ~/.config/biggrinrtx/xai.key (chmod 600)
  term: krtx-term → grok hello

OS DESKTOP · multi-tab · SDF bus
  ./bin/pack-os-desktop          # out/desktop_os.html + headers.json
  ./bin/launch-os-desktop        # native engine sheet (comp SPV)
  js/desktop.js  · multi-seat tabs (SPV per tab · stay alive)
  js/bus.js      · SDF speak on BGS/BGF · insecure|secure|broadcast
  designer headers = icons + Start launchers (spvs/headers.json)
  chat: /bus secure · /lane BGF · /in term · /say hi · /peers · /spit

ZERO2D · 2D zero-cost demo · SPV HOME VISUAL
  ./build.sh
  ./bin/krtx-zero2d --detect          # Wayland · X11 · GL · RTX JSON
  ./bin/krtx-zero2d                   # native GL window · no host browser
