source.sx refactored to a single published-posts batch query returning full rows
(incl. lexical) — the existing post-by-id/slug DTO lacks lexical (sx_content/html
only), so the canonical lexical->blocks path needs a dedicated migration provider.
backfill-ids! now filters client-side (no extra query).
drafts/published-posts.sx + drafts/README.md: paste-ready blog-app change (defquery +
SqlBlogService.list_published_posts returning rows incl. raw lexical). README updated.
source 21/21; total 76/76.

source.sx: live-source adapter resolving Q-M4 (internal-data query, not direct PG).
Injected fetch-fn transport port (hexagonal seam); parse-row maps a blog post-row to
the importer post dict and parses the :lexical JSON string via dream-json-parse.
End-to-end drivers: backfill! (enumerate->fetch->import) and sync-verify
(enumerate->fetch->verify), + backfill-ids! explicit-id fallback.
Tests mock the transport against the documented response contract incl. a real lexical
JSON string. README flags the one blog-side gap (add a published-posts enumeration
query) + production fetch_data wiring (lives in lib/host). source 20/20; total 75/75.
