Remove tests that copy app logic into the test, grep PHP source as
text, only check literals, constants, class_exists or PHP built-ins,
duplicate other tests, or are always skipped. Keep source checks that
guard security and authorization rules.
Rename a duplicate Pest helper so the full suite loads, drop the
missing v5/Browser path, and remove the CLAUDE.md symlink in favor of
AGENTS.md. Correct AGENTS.md: Dusk is not installed and the upgrade
script is scripts/upgrade.sh.
Constrain dev_helper_version to Docker tag grammar
([A-Za-z0-9_][A-Za-z0-9_.-]{0,127}), re-validate before triggering the
helper image build, and interpolate the image reference via
escapeshellarg() when composing the docker build command.
