what do deliverable statuses mean (writing, generating, ready, scheduled, posted, failed)?

each deliverable shows one of six statuses.

• writing: dibs is still writing the brief.
• generating: dibs is generating the deliverable.
• ready: generated and ready to download, schedule or post.
• scheduled: on the posting schedule, or set to post at a specific time.
• posted: already published, and, once connected, showing its performance.
• failed: something went wrong while generating; generate it again from its brief.
