# FIG. 1 — Reference numerals

Bounded-authority actuation system. The numbering follows patent drafting
convention because it is a compact way to label a system diagram, and the
SVG is unfilled line art for the same reason. The five provisional
applications are listed on the [investor page](/investors); no patent has been
granted.

| Ref | Element |
|-----|---------|
| 100 | Bounded-authority actuation system |
| 110 | Host compute subsystem (untrusted, off-board) |
| 112 | Graphics processing unit |
| 114 | Language model planner |
| 120 | Serial interface (program and parameters in, verdicts out) |
| 130 | Authority gate |
| 132 | Soft processor |
| 134 | Verified interpreter, fuel-bounded |
| 136 | Capability table |
| 138 | Envelope monitor (multi-point, predicted stop) |
| 140 | Secure element |
| 142 | Audit signer |
| 144 | Constructed effect interface |
| 150 | Actuator plane |
| 152 | Driver stage (PWM / step-direction) |
| 154 | Servo drive |
| 156 | Actuator |
| 160 | Independent safety chain (series interruption) |
| 162 | Emergency stop |
| 164 | Contactor |

**The relations that carry the architecture:** authority terminates at 130
rather than at 110; 110 reaches 150 only through 130; 160 bypasses 130
entirely and interrupts 154 in series. 130 regenerates the drive-facing
command and so can produce motion; 160 can remove drive power without 130's
cooperation.
