# Sensor slots, cheapest first. Credo is cheap enough that it lives in
# `check`, not here. Add a sensor as its yak lands, both as a target and to
# VERIFY_SENSORS — that variable is the single source of truth for what this
# target reports as wired.
#   - sobelow    (yak: sobelow in the Lens pass)
#   - coverage   (yak: coverage floors + framework-glue exclusions policy)
#                  WIRED below (test.coverage + coverage).
#   - crap       (yak: CRAP scores with ex_crap (both apps))
#   - mutation   (yak: mutation testing with muex — a sensor, not a gate)
#
# Runtime note: the coverage sensor exports from a single suite run
# (`test.coverage` -> `mix test --cover --export-coverage default`) that CRAP is
# meant to reuse, instead of running the suite twice.
#
# The suite runs FIRST, because it is what produces the coverage export the
# sensors read; sensors still run cheapest-first among themselves.
