active_high was hardcoded to True, so an LED wired the other way
round - cathode to the pin, anode to 3.3 V, or an inverting
transistor driver - had no configuration at all. The symptom is easy
to misread as a dark LED: the light actually does the opposite, on
with no card and off with one.
Exposed as --led-active-low on the app and on install.sh, which
rewrites the unit's ExecStart like the other LED options. The
startup line now names the polarity, so the journal says which
configuration is actually running:
LED on GPIO 23 (presence mode, active-high, gpiozero)
Default is unchanged, so existing installs behave identically.
