# next/tests/define_trigger.sh — fed-sx triggers Phase 1 (verb).
#
# The DefineTrigger genesis verb
# (next/genesis/activity-types/define_trigger.sx) binds an activity-type
# to a flow. This suite confirms it parses with the expected
# DefineActivity head + :name, that its :schema accepts a well-formed
# binding and rejects malformed ones, and that a DefineTrigger envelope
# round-trips through term_codec.
