# The two classes this operator's own pod claims through. They ship
# with the base because the claim template in operator.yaml names
# them literally: they are wiring, not policy, and the operator
# cannot start without them. The classes your workloads claim
# through, such as an output class, are the cluster owner's
# vocabulary to create, and the install guide gives the YAML.

# The graphics card's card node, as liken publishes it. The card
# node allocates once, which is what makes the claim holder the only
# program setting a mode on it. The selector reads the displayNode
# attribute rather than a vendor and a product id, so it stays
# correct across a fleet of different machines.

# The graphics card's monitor-control wires. liken publishes the
# card's i2c buses as one exclusive companion device, apart from the
# card node, because raw wire access has one writer and no
# arbitration contract. This operator is that writer: it claims the
# companion, probes each panel over DDC/CI, and re-publishes the
# wires at the per-connector grain as its control devices. The
# selector reads the subsystem and the class, so it stays correct
# across a fleet of different cards.
