Show me how gave the commands the audit runs: sed, awk and yq edits,
heredoc manifests, JSON patches, --overrides, sleeps and wait loops -
nothing anyone types in the exam. A step's show is now a list of
parts (sim/bank.py): cmd() is what you type as it stands; hand() is
what you do by hand - vim on a generated skeleton or on a manifest
pasted from the docs page it names, kubectl edit, ssh NODE and sudo
-i, a value you read and echo - with a script that does the same for
the audit. All 135 CKA steps are rewritten so, with k for kubectl;
their checks, titles and texts are unchanged.
Add ./ksim lesson lint, which reads what every step has you type and
flags scripts. The lesson audit runs it first.
Record the hosts whose setup failed when a session started. The page
warns above that task or lesson and offers Rebuild this host; the CLI
names ./ksim reset N on each step.
Render *italics* in lessons and tasks, outside code spans.
Audited on v1.37: CKA lessons 27/27, 135/135 steps, done the exam
way; lint clean. kubectl edit --subresource resize, the one edit the
audit replaces with a patch, was proven on its own.

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.
