# Snapshot Job — copies prod DB into an experiment slot via sqlite3 .backup
# Usage: set SLOT to alpha, beta, or gamma before applying
#
#   SLOT=alpha && sed "s/SLOT/${SLOT}/g" snapshot-job.yaml | kubectl apply -f -
#
# The job completes and self-deletes after 5 minutes.
# Always snapshot before deploying a new experiment to a slot.
