What happens if a post gets stuck Sending

Sometimes a post gets stuck on 'Sending…' — flaky signal, an app kill mid-upload, a social network being slow. GlueArrow now self-recovers these. If an envelope has been sending for longer than 10 minutes, the next time you open the app (or the next worker tick, whichever comes first) it flips to 'Sent' with the note 'stuck-sending recovered — verify on socials'. The note means exactly what it says — the app stopped waiting, but it can't promise the post actually landed on every network. Open the platform (Facebook, Instagram, X, TikTok, LinkedIn, YouTube) and check. If a network is missing the post, hit Re-publish. You're safe to do that: the backend dedupes outbox retries by (you, network, post_id) for 6 hours, so re-publishing what already landed will short-circuit instead of double-posting.
