Following real software

Each part of the twin can either simulate its state or mirror real software:

de-twin serve --shm --mirror-temchannel 10.0.0.5     # a real microscope (or the Dummy channel) drives the twin
de-twin serve --deapi --holder impulse               # a DENS Impulse holder, or DENS's own simulator, drives the twin

• MirrorColumn polls a DE-TEM-Channel with the same batch command DE-Server uses and forwards writes to it. It also reads a real corrector’s last measured aberrations.

• ImpulseFollower reads temperature and bias through impulsePy (pip install "de-twin[impulse]"); without impulsePy or a responding holder it falls back to the simulated heating chip and says why.

The twin then renders what the real column and holder report.
