-- 035_job_post_recruiter_ids.sql
-- A job post can have more than one recruiter. current_recruiter_id stays the
-- first / primary pointer so existing joins and filters keep working;
-- current_recruiter_ids is the full JSONB list used by create / update / get.
-- Applied at startup by alembic_setup.run_manual_sql(). Needed because prod
-- boots with DB_AUTOGENERATE=false.
