KateRTX LAW · LINEAR LINE · PINS
================================
1. Project lives only under Desktop/x/KateRTX
2. No symlinks · no host-home install required
3. SPV AND ELF: plugs + krtx-engine + krtx-term
4. LINEAR = one ordered line · many pins · no duo mash
     BGS  ground  pin · field_one(v)=v|1
     BGF  measure pin · (a-b)|1
     BGL  secure clean pin · surface|1 · field hygiene AV
       · EZZIE  (a^b)|1      free eor on BGF
       · PHI    (d*s)|1      scale on BGF
       · THERMO cool|warm|hot|1  heat band on BGF
     SDF  place   pin · shell · raised · store
     SPV  free ride · |1 · never folds into SDF/BGS
5. EZZIE · PHI · THERMO still linear — atoms on BGF, not side engines
   ESSIE = hotswap system · NOT EZZIE
6. free=1 / KNOW / GRIN = TRUTH pin · NOT “only one engine”
   know_her = 7|1 · Hostess TOP · not ground
7. BGF is meter · SDF is place · both on the line
8. TRUTH local · no curl · God Bless
9. OS DESKTOP is the product · not demo plugs · not AV-as-home
     home = os_desktop · runtime = js/desktop.js · ESSIE multi-seats
     compositor = krtx-engine · utilities (antivirus/cook) stay off home
     bus = js/bus.js · SDF on BGS/BGF · insecure|secure|broadcast
     designer headers = icons + launchers · spvs/headers.json
