<p>The Exploded Cluster teaches how modern container platforms work by taking them apart -

real components and wired to your scroll, so the architecture moves while the words explain it.

your container as a <b>random non-root UID</b> - your image has to cope. Workloads that
genuinely need privilege get a dedicated ServiceAccount bound to a minimal custom SCC,
never the stock one.</p>
<h3>The platform runs itself</h3>
<p><b>Routes</b> predate Ingress and still rule here. <b>Operators</b> run the platform's own
machinery. The OS underneath is immutable - changed by <b>MachineConfig</b>, never by SSH.
And <b>SNO</b> puts the entire promise on one box at the edge. At fleet scale the labels
from Course VI decide which of these boxes runs what.</p>
