A fixed CKAD set (ids 38-57, 140 points, 120 minutes), run with
`./exam sim a`. It is kept out of the random pool, so reruns are
comparable. The scenarios are original - a fictional river-freight company,
one Namespace per river - and practise the techniques the killer.sh CKAD
environment is known for without reusing its questions: exact names and
file outputs, commands written to scripts, several steps per task.
It covers what the pool never asks: debugging a container with no shell
through an ephemeral container (the value lives only in the process's
environment), a Kustomize patch with a hashed configMapGenerator, a Helm
release stuck in `failed`, a CronJob run by hand while suspended, fsGroup
on a shared volume, RBAC proven by the app's own log, Pods rejected by a
LimitRange, and the two-source NetworkPolicy trap (enforced by kindnet).
Verified on a throwaway cluster: every task scores 0 untouched and 7/7 when
solved, and a full sitting (baseline, seed all 20, solve, grade at the end)
scored 140/140 twice on the final code.
