lib_dev/ was both compiled (elixirc_paths for :dev and :test) and source-loaded
by credo through `requires:` in .credo.exs. Two load paths for one module means
that whenever _build/dev already holds the beam, `mix credo` warned:
warning: redefining module Firehose.Checks.NoConnShadowing
(current version loaded from _build/dev/.../Elixir.Firehose.Checks.NoConnShadowing.beam)
Keep the explicit contract and drop the accidental one: `requires:` is the
documented way for credo to load project checks, so lib_dev/ now leaves
elixirc_paths in every environment. Nothing under test/ referenced the check, so
the :test entry was dead as well, and credo compiles the file on every run
anyway, so the check still gets compiled — just once.
One-time migration for checkouts that already built it:
`mix clean` (or delete _build/dev) to drop the stale beam; until then the old
warning persists. Fresh clones are unaffected.
