	name: CI

	# Runs the same checks as `mix precommit` (compile --warnings-as-errors,
	# unused-deps, format, credo --strict, tests) on every pull request, which is
	# the gate: the only way into main is a merged, CI-green PR.
	#
	# The push-to-main run is deliberately NOT the belt-and-braces copy it used to
	# be. With the squash-merge flow it re-tested the same tree the PR had just
	# tested green, so every change cost two full runs and the second one had
	# almost nothing left to catch. What it did still earn is the shared build
	# cache: a cache written on a PR branch is not visible to other PRs, so only a
	# run on the default branch refreshes the one every branch restores from. That
	# cache is keyed on `mix.lock` + `config/*.exs`, so main now runs exactly when
	# its key changes — which is both when the cache needs refreshing and when the
	# change is riskiest.
	#
	# The trade this accepts: two PRs that are each green alone but conflict once
	# merged are no longer caught here. The deploy's own build and `/health` gate
	# is what stands behind that.
