Band Review Board: Multi-Region Ad Compliance
Global brands ship one campaign to many markets, and the same claim can be legal in the US and a violation in the EU, where fines reach 4 to 10% of global revenue. Today the only defense is slow, market-by-market legal review with no audit trail. Band Review Board replaces that with a room of 10 specialist agents that clears a campaign against every market's rules at once. It is not a pipeline that merges a checklist of flags. The agents hold competing mandates, claims, regulation, and brand, and they argue. Region reviewers hold or concede on the record, a mediator brokers the conflict, and a human rules only on the genuine gray area, with that ruling logged as precedent. It runs on Band as the real coordination layer, not a wrapper. Agents @mention each other to object and rebut between specific parties, the room summons the next specialist, and finally a human, with addParticipant only when a conflict will not resolve, and every finding and verdict posts to a shared live ledger with sendEvent. Take Band out and it stops working. Every agent runs the model that fits its job through one AI/ML API gateway: GPT-5, Gemini 2.5 Pro and Flash, Claude Opus, Sonnet, and Haiku, Llama via Featherless, DeepSeek, and Nano Banana for image regeneration. Cost scales with difficulty: cheap models do the back-and-forth and Opus is spent only on a deadlock. It is also multimodal, reading the video and hearing the audio. In the live demo, the claim "clinically proven to boost your immune system" is approved in the US, a violation in the EU, and conditional in LATAM. The room genuinely deadlocks and escalates to a human. Nothing is hard-coded. Try it live at artifact-viewer-one.vercel.app. Solo build, MIT licensed.
