Real switches and pixels respond through the same controller family selected for QEC-1.
FIRST PHYSICAL MILESTONE / BUILD BEFORE PANEL
Prove the machine small.
QEC-1P is the reduced electrical and protocol proof for QEC-1. Four physical keys enter אור and STEP; four pixels expose node, path, register, and link/fault state. It proves the part that must work before any 600 × 420 mm panel is cut.
BROWSER BENCH CONSOLE
Generate evidence, not impressions.
Simulation proves the published protocol logic in any modern browser. Live proof uses Web Serial in a supported Chromium browser to negotiate with the Pico, apply the active Console run (or the three-state אור default), reject excess brightness, and observe the watchdog fault.
No serial device connected. Simulation is ready.

QEC-1P bench console ready.
Electrical boundary: The Pico is powered by USB. The four-pixel rail uses a separate fused 5 V supply. Their grounds meet at the 74AHCT125 logic-shifter point; their positive rails never meet. No mains voltage enters the prototype.
WHAT THIS PROVES
A gate before fabrication.
The prototype does not imitate the full panel. It retires five specific risks: low-voltage power, 3.3 V-to-5 V data translation, physical key debounce, bounded serial frames, and fail-closed behavior.
The host remains authoritative for state; the panel only displays validated projections.
אור, light, becomes the acceptance program: frame, connection, and manifestation made observable.
