	- name: Checkout code
	uses: actions/checkout@9c091bb21b7c1c1d1991bb908d89e4e9dddfe3e0 # v7.0.0

	# Stage 1 — PHP syntax check
	# Uses kanboard/kanboard image with entrypoint override (default entrypoint
	# starts Apache and runs forever; we override to /bin/sh for one-shot use).
	- name: Lint — PHP syntax check
	run: bash scripts/docker-lint.sh

	# Stage 2 — Install Composer dependencies
	# vendor/ is not committed (.gitignore); install it here so the remaining
	# stages can find vendor/bin/phpcs, vendor/bin/phpstan, vendor/bin/phpunit.
	- name: Install Composer dependencies
	run: \|
	docker run --rm \
	-v "$PWD":/app \
	composer:2 \
	install --no-interaction --prefer-dist --no-progress

	# Stage 3 — PSR-12 code style check
	- name: PHPCS — PSR-12 style check
	run: bash scripts/docker-phpcs.sh

	# Stage 4 — Static analysis (PHPStan level 5)
	# Uses php:8.4-cli — kanboard/kanboard lacks the tokenizer extension
	# required by PHPStan.
	- name: PHPStan — static analysis
	run: bash scripts/docker-phpstan.sh

	# Stage 5 — Unit tests
	# Uses php:8.4-cli for the same reason as PHPStan above.
	- name: PHPUnit — unit tests
	run: bash scripts/docker-test.sh
