The strong way is `payload` — a strong-ref to a record on whichever ATProto app owns the data (plyr.fm track, standard.site post, etc.), which is content-addressed, verifiable, and portable. The fallback is `url` — a plain link, for deliverables that don't live on ATProto yet (an itch.io build, a hosted doc). Prefer payload; `url` is the humble alternative. The lexicon can't express \"one-of\" across fields, so both are optional here and the \"at least one\" rule is enforced in code (Submission.getDeliverable). The submitter's DID is implicit (the record creator).",
