-- 036_candidate_source_links.sql
-- Scored `candidates` rows point at the application that owns the CV text.
-- Extract lives on inbox_messages.resume_text / manual_upload_candidate.full_text
-- (so Inbox and CV Bank can fetch it). Do not duplicate that blob here.
-- Drops resume_text if an earlier draft of this file added it.
-- Applied at startup by alembic_setup.run_manual_sql().
