kubestronaut-sim runs each exam task on a host of its own - a kind (kubeadm) cluster in rootless podman, or a QEMU/KVM Ubuntu VM for the CKS tasks that need their own kernel (Falco, AppArmor) - and puts a browser desktop in front of them, the way killer.sh and sailor.sh do. - ksim, sim/: the engine (sessions, drills, study mode, grading, coverage, audit), host and VM lifecycle, the desktop - images/: exam host images (common, CKS variant with its tools, VM guest) - cka/ (131 tasks), ckad/ (105), cks/ (110): task banks, curricula with study notes, reference solutions and scripted solutions Every domain of every track has at least 17 pool tasks. `./ksim audit` proves a task three ways: it seeds cleanly on its own host, scores nothing before anyone has worked on it, and reaches full marks when its scripted solution is run on the host as `candidate`. All 346 tasks pass (CKA audited 2026-10-13, CKAD and CKS 2026-10-12). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JZPd3GGWyxTgAkL6a4gAJz

# It is the "base" machine of a session - no kubeconfig here; every task says which host to ssh to.
