# Small by design and never absent. An absence that means "no requirement"
# cannot be told from an absence that means somebody forgot, so a
# schema-one bundle without this file is invalid and says so.

# The lowest engine that can land this release. Most releases need no more
# than the payload schema already implies: an engine that cannot decode the
# schema refuses at the declaration long before it reads this line. Raise
# it only where a release needs something a decoder alone does not give.

# Versions an upgrade may not skip. A plan whose interval crosses one is
# blocked naming it, and the operator plans toward that version first. The
# engine never takes the small step on its own.
