Syncing

• First sync: page through /companies/{id}/assets until nextCursor is null.
• Later syncs: pass since set to the newest uploadDate you’ve seen.
• Late transcripts: a video can arrive before its transcript. Re-check /assets/{id} while status is processing, or while a video or audio asset has hasTranscript: false, for up to about 30 minutes after upload.
• Deleted assets: there’s no deletion feed. A deleted asset returns 404.
