Quorum — Multi-Agent Compliance Board on Band

Shipping software means clearing a gauntlet of compliance checks — data-privacy law, open-source licenses, app-store rules, accessibility. Today those are four separate, manual, late-stage reviews, and problems slip through. Quorum replaces them with a board of specialist AI auditors that review a release together and reach one verdict. Each agent owns a domain — Legal (GDPR/CCPA and data security), License (open-source and copyleft risk), Mobile (App Store / Google Play), and Accessibility (WCAG 2.2) — and they coordinate directly over Band. A human kicks it off with one message; the Coordinator @mentions the four specialists, each reads the codebase and reports back, and the Coordinator reconciles everything into a single go/no-go Release Gate. The reconciliation is the point, and what a single agent can't do. The same AGPL session-replay library gets flagged by Legal (it captures passwords), License (a copyleft violation), and Mobile (tracking without consent); Quorum merges all three into one top-priority blocker, with a severity rollup and a prioritized fix plan. We demo it against "Snaptab", a deliberately broken receipt-scanning app: Quorum returns NO-GO with 19 critical issues across seven cross-domain blockers — every planted problem caught. Built on Band's agent-coordination layer — agents talk via @mentions over WebSocket, with Band operations exposed to them as native tools — running OpenCode agents on Gemini through OpenRouter. Quorum turns release compliance from a checklist into a conversation: the gate, before your users hit it.
