• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: composer.lock

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires phpunit/phpunit ^13.0.0 -> satisfiable by phpunit/phpunit[13.0.0].
    - phpunit/phpunit 13.0.0 requires sebastian/diff ^8.0.0 -> found sebastian/diff[8.0.0] but these were not loaded, likely because it conflicts with another require.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
