+# ── Marketplace-installed plugins ──
+#
+# A plugin fetched from the marketplace is a CLONE with its own .git and its own repository. Left
+# tracked, `git add -A` after an install commits it as a gitlink — a pointer to a commit this repo does
+# not contain, which then breaks anyone who clones the platform and does not have access to that plugin.
+# Happened on 2026-08-15, one commit after the marketplace landed.
+#
+# The plugins that genuinely ship with the platform are re-included by name below. Adding one is a
+# deliberate act, so keeping this list by hand is the right amount of friction — an unlisted plugin
+# directory is an install, not a source file.
