Living diagrams.

The site's drawing language, set in motion — a monitored signal chain, a fault-handling trace, and the safety state machine. Flat 2D, zero dependencies, matched to the cxtech.me light and dark themes.

FIG. 03-A MONITORED SIGNAL CHAIN — BLOCK-DIA SYSTEM NOMINAL

Watchdog path, flat schematic. Program-flow fault silences the alive signal · window watchdog expires · safety monitor asserts /SS and isolates the output stage.

FIG. 03-B FAULT-HANDLING TRACE — FTTI SYSTEM NOMINAL

Five channels, one sweep. Feedback diverges at the fault, the alive line flatlines, detection and reaction land inside the FTTI budget — before the hazard boundary.

FIG. 03-C SAFETY STATE MACHINE — SM-FSM-SAFETY-01 INIT · BIST RUNNING

Two laps. Lap one degrades gracefully — FAULT_1 to limp, CRIT to safe stop, reset. Lap two takes the direct edge: watchdog timeout straight to safe stop.
