plan 0012: updates blog follow-ups — draft visibility fix + RSS feed#356
Merged
Conversation
The public reads relied on RLS alone, but policies OR together: an admin's session satisfies 'Admins read all posts', so their own drafts showed up on /updates. The public queries now filter published=true explicitly; RLS stays the gate for everyone else.

New rss-feed edge function renders the RSS 2.0 feed server-side — feed readers can't run the SPA and hosting is static-assets-only. Anon-key read of published posts (RLS gate), 15-min edge cache, tags as categories. lib/rssFeed.ts derives the URL from the baked backend; /updates gets a subscribe pill and both public pages emit the rel=alternate autodiscovery link via a new useDocumentHead feedUrl option.

Summary
Two follow-ups to the updates blog (#352, plan 0012) that landed after that PR merged:
/updates. The public reads (fetchPublishedPosts,fetchPostBySlug) now filterpublished = trueexplicitly; RLS remains the gate for everyone else. Anonymous visitors were never affected.rss-feededge function renders the RSS 2.0 feed server-side (feed readers can't run the SPA and hosting is static-assets-only): anon-key read of published posts through RLS, excerpt descriptions, tags as<category>, 15-minute edge cache./updatesgets an "RSS feed" subscribe pill, and both public pages emit the<link rel="alternate" type="application/rss+xml">autodiscovery tag (newfeedUrloption onuseDocumentHead).lib/rssFeed.tsderives the feed URL from the bakedVITE_SUPABASE_URL, so each deployment links its own backend. Registered insupabase/config.toml(verify_jwt = false).The feed lives on the Supabase functions domain; a pretty same-domain URL (
/feed.xml) would need a Cloudflare Worker script — same deferred infrastructure as per-post OG cards, noted in the plan doc.Related Issues
