## 2. Core Governance Capabilities

1. **Team Invitations:** Cryptographically secure 40-character single-use tokens expiring in 7 days.
2. **Role Matrix:** Minimal 3-tier hierarchy (`owner`, `admin`, `member`) enforced server-side.
3. **Owner Safeguards:** Strict validation prevents accidental deletion or demotion of the last remaining workspace owner.
4. **Audit Log:** Captures administrative, security, role, and configuration changes while automatically redacting sensitive secrets (passwords, tokens, API keys).
5. **System Health:** Provides real-time operational status of outbound SMTP, heuristic/AI engine, database, and background follow-up queues.
