# Runs the test suite against every supported PHP interpreter (7.0 - 8.4).
#
# composer.lock is resolved for PHP >= 8.2 (phpunit 11). Older interpreters
# need a compatible phpunit ("^4.8 || ^9.6 || ^11.0" in composer.json), so
# this script re-resolves the phpunit requirement with each interpreter before
# running it. Any nonzero composer/phpunit exit fails the whole run - a partial
# run must never look green. Interpreters that are not installed are reported
# and skipped (the run is marked incomplete rather than passing).
