   # Statuses and checks apply to specific commits (by hash). 
   # Enforcement of required checks is done both at the PR level and the merge queue level.
   # In case of multiple commits in a single PR, the hash of the squashed commit 
   # will not match the one for the latest (approved) commit in the PR.
   # We auto approve the check for the merge queue for two reasons:
   # * Queue times out due to duration of tests.
   # * Avoid running integration tests twice, since it was already run at the tip of the branch before squashing.
+  # Additionally, integration tests are not run on docs-only changes.
