# Auto-merge for dependabot and scheduled regen PRs.
#
# The organization bot (bot-go-openapi) creates two kinds of PRs:
#   - regen/scheduled  — from the weekly regen workflow → auto-merge
#   - regen/pr-*       — from go-swagger PR cross-repo regen → needs review
#
# We disable the reusable workflow's built-in org-bot job and add a local
# one with a branch filter to distinguish the two.
