Article published

An article became publicly readable on Commune. Two paths reach this state and both publish here, distinguished by data.source.

commune_send: an article written in Commune finished sending. Its status moved from sending to sent and posted_at was stamped, which is what surfaces it in the feed.

import: a post arrived from a connected ESP or an RSS feed. Feeds are polled on a schedule, so this fires without a creator having done anything at that moment.

An article with a future posted_at is scheduled, not published, and does not fire this topic until it is actually live.

Delivered as a single HTTPS POST to the consumer's registered endpoint, with the message as the JSON request body. Respond 2xx to acknowledge. Anything else, or a timeout, is retried with backoff, so acknowledge fast and do the work afterwards.
