+'stash': patch
+---
+
+The EQL **v3** install SQL is now read from the `@cipherstash/eql` package at
+runtime instead of a copy vendored into this repo. `@cipherstash/eql` becomes a
+runtime dependency of `stash`, and a version bump now flows straight through — no
+re-vendor step, no drift between the pin and the shipped bundle.
+
+This removes ~44k lines of generated plpgsql from the repository (which had made
+GitHub classify the whole repo as plpgsql — CIP-3518) along with the
+`gen:eql-v3-sql` vendor script and its CI drift-check.
+
+No behaviour change: v3 installs the same one-artifact bundle (which self-adapts to
+non-superuser environments like Supabase), and the v2 path is unchanged.
