Public read-only coinos community chat at /chat — a share-anywhere link that shows the live chat history to anyone, logged in or not, with a "Sign in to chat" button ("Open coinos" when the device already has an account). No server-side decoder needed: the community's join material was already public by construction (baked into the client bundle — every coinos user is meant to be a member), so the page derives the stream keys and decrypts wraps client-side exactly like the app's Chat tab, worker-offloaded with the same sliced fallback. Renders messages + edits + deletes + reactions and honors the folded control state's ban list; presence/typing/guestbook deliberately omitted. Profiles come from ONE batched kind-0 query per burst (a REQ per author tripped relay concurrency limits). Plumbing: the join material moved to src/community.js (shared with messages.js so they can never drift), /chat is excluded from the single-segment profile deep-link (which was eating the path and rewriting the URL before the route ran), and app renders stand down in public-chat mode so a feature-init render can't paint onboarding over the page. Verified headless against the live relays: 59 messages decrypt, ban-fold applies, names resolve
