"description": "An Audience is a list of user identifiers Vibe can target or exclude. You populate an audience by opening a **sync**, uploading one or more **batches** of identifiers, then marking the final batch with `last_batch_flag: true`.\n\nConcurrency: only one non-terminal sync may exist per audience at a time. Syncs expire after 24 hours of inactivity.\n\n> ⚠️ **Gotcha — silent zero-match failures**\n>\n> If your identifiers are hashed with the wrong algorithm or normalization, the sync will succeed and the audience will show as Active, but it will match zero CTV profiles. There is no error signal. See the [HEM format specification](https://developers.vibe.co/docs/hem-format) for the exact requirements."
