Shemot 16: dvar yom b'yomo, and on the sixth day double, and none on the seventh. Every night at 00:00Z the day's provision went stale and the readiness probe failed until someone woke — 13.5 hours on 2026-10-15. CronJob `manna` (deploy/k8s/manna-cronjob.yaml) runs at 00:01Z Sunday to Friday in our own korban-processor image, mounts the manna PVC as the app's uid, and writes today.json from the ConfigMap's MANNA_* amounts — doubled on Friday, valid to Sunday 00:30Z. The pipeline now accepts Friday's `double` on Saturday (validate_date/3) and nothing else across a day boundary; three tests. The kohen sets the amounts, may still write by hand, and reads a failed job as the Day-4 alarm (KOHEN "The manna, each morning"; Tamid §1.1). Doorpost re-pinned. Elixir green.
