Add lessons: untimed guided labs, one per curriculum objective, on a
host of their own, in the browser and in the terminal. Each step has
a check, a hint and its commands; a lesson writes no history or
scores, only a done mark on its objective. CKAD 2.1-2.4 (24 steps)
and all 27 CKA objectives (135 steps) have one, and `./ksim lesson
audit` proves that every step fails, is done by its own commands,
then passes.
Add CKA tasks 132-147 (cka/bank_course.py) on what a full CKA course
teaches beyond the bank: a real upgrade from v1.36, a drain under a
PodDisruptionBudget, QoS and eviction, in-place resize, kube-proxy's
chains, encryption at rest, an operator, and CSI expansion, snapshots
and clones (ensure_csi_hostpath).
Move CKA and CKS to Kubernetes v1.37 and rebuild the hosts on Ubuntu
24.04, with kubelet, kubeadm and kubectl as held packages from
pkgs.k8s.io; the desktop runs Ubuntu too. Hosts gain man pages,
hexdump and xxd.
Fix CKS Q4, which gave 3 of 12 points untouched, and CKA Q4 and Q49,
whose solutions raced their new CRD.
Audited on v1.37: CKA 147/147, CKAD 105/105, CKS 109/110 (Q103, a
Falco task, failed to seed once and awaits a re-audit); lessons: 135
of 135 CKA steps and 24 of 24 CKAD steps.

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).
