 # standardwebhooks declaration survived, which is where Ruby's ci.yml guard would sit if

+# auto-merge.yml is hand-written and arms Fern's own regeneration PRs. On pull_request_target
+# it enables auto-merge (squash) for a pull request opened by fern-api[bot] from an in-repo
+# fern-bot/* branch against the default branch, so the pull request merges itself once main's
+# required status checks pass. The trigger is pull_request_target rather than pull_request so
+# the workflow that arms a pull request is always the copy already on the base branch, never
+# the copy that pull request carries.
