host: blog persisted in durable SX store + materialised view, 158/158
Blog posts now live in the durable SX store (persist/durable-backend, on-disk
under $SX_PERSIST_DIR — already built: sx_persist_store.ml + lib/persist/
durable.sx). Publishing appends insert ops to the slug's content stream; posts
survive restarts (verified: seq/log stable across container restart, re-seed
idempotent).

Read path: http-listen handlers can't drive per-request perform/IO (sx_call
doesn't resolve the CEK IO suspension the way the main loop does), so posts are
materialised from the store into an in-memory view at boot (host/blog-load-all!
+ host/blog-seed!) and request handlers read the view — perform-free. Store is
source of truth; view is a boot-rebuilt cache.

Deploy: docker-compose.dev-sx-host.yml mounts /root/sx-host-persist (chowned to
appuser 10001) at /data/persist; SX_PERSIST_DIR set. blog.rose-ash.com/welcome/
live. Per-request-IO kernel fix tracked in the plan as the next task.

# host-on-sx live service — the SX web host (lib/host) served by the native
# http-listen server via lib/host/serve.sh. Joins the sx-dev project + externalnet
# so Caddy can reverse_proxy a subdomain to it (blog.rose-ash.com). Isolated from
# the sx_docs server: separate container, separate port.
#
# Usage:
# docker compose -p sx-dev -f docker-compose.dev-sx-host.yml up -d sx_host
# docker compose -p sx-dev -f docker-compose.dev-sx-host.yml logs -f sx_host
# docker compose -p sx-dev -f docker-compose.dev-sx-host.yml down
