queries.feed was the main chokepoint, but several discovery paths have their own
SQL. Apply the shared source exclusion to all of them so "no paywalls" is truly
site-wide:
- briefs.build_daily_brief: EXCLUDE paywalled candidates (was: demote) — never
stored in a new brief.
- queries.brief: stored-brief retrieval (covers /today + /api/brief) filters the
paywalled source.
- digest.digest_items + followed_digest_items: the morning email + "from what you
follow" omit paywalled sources.
- sitemap(): paywalled article pages excluded from the sitemap.
All reuse queries.paywalled_source_ids (admin override still wins).
Regression tests (test_paywall_exclusion.py): never stored in a new brief; /today
+ digest omit it; followed-source email omits it; Saved retains it; 'free'
override restores eligibility. 423 backend tests green.
