scripts/snapshot.mjs renders every public page (home, browse, publish,
boundaries, 8 categories, every active listing) to <out>/<path>/index.html,
plus /sitemap.xml, /robots.txt, and the two static assets. Writing to a
directory next to the service AND uploading via `aws s3 sync` are two
flags on the same command: --out to pick the directory, --upload to push.
Live routes added for /sitemap.xml and /robots.txt so a crawler hitting
the live service sees the same enumeration the snapshot bakes into the
bucket. renderSitemap / renderRobots in service/seo.js are the single
rendering path both call sites use.
Scope deliberately limited to the browse surface — /submit and the API
routes depend on the live backend and were never going to work on a
static mirror. The browse surface IS what the fallback is for: readers
survive an outage, publishers can't.
systemd unit + timer under deploy/ run the snapshot weekly on Sunday
04:00 UTC with 30 min jitter and Persistent=yes so a missed run after a
reboot catches up. Unit uses the sia-storage AWS profile per
[[sia-storage-credentials-location]] and the per-process endpoint URL
baked in via Environment=.
Local dry-run against an empty DB produced 14 HTML files + sitemap +
robots + the two assets.
