+# Changesets release automation (Version-PR pattern).
+#
+# On every push to main, this opens/updates a "Version Packages" PR that runs
+# `npm run version-packages` (changeset version -> sync-plugin-manifest -> sync-versions --fix),
+# accumulating all pending changesets into one version bump. Merging that PR
+# bumps plugin.json + marketplace.json + cdp-bridge, updates CHANGELOGs, and
+# consumes the changesets — making the new version installable from the marketplace.
+#
+# No npm publish: the "package" is the plugin manifest the marketplace reads
+# from the repo, so only the version half of changesets/action is used.
+#
+# PREREQUISITES (must be enabled in repo settings — cannot be set from this file):
+#   - Settings > Actions > General > "Allow GitHub Actions to create and approve pull requests"
+#   - Settings > General > "Allow auto-merge"
+#   - Branch protection on main with >=1 required status check (so `gh pr merge --auto`
+#     has a check to gate on; otherwise auto-merge has nothing to wait for).
