- Drop global unique constraint on news_articles.url; replace with (bill_id, url) so the same article can appear for multiple bills - news_fetcher dedup now scoped to bill_id instead of global URL - Bill detail endpoint triggers a background news fetch when no articles are stored, so gnews articles surface on next load Migration 0009.

"""fix news_articles url uniqueness to per-bill scope
|
|
|
|
Previously url was globally unique, meaning the same article could only
|
|
be stored for one bill. This changes it to (bill_id, url) unique so the
|
|
same article can appear in multiple bills' news panels.
