Provenance: Pricing re-verified directly from knock.app/pricing on 2026-06-19 (Developer $0, Starter $250, Enterprise 'Contact us'). Compliance from docs.knock.app/developer-tools/security: 'Knock is SOC 2 Type 2 compliant, GDPR certified, CCPA, and HIPAA compliant.' That page does NOT explicitly confirm a BAA (directs to security@knock.app), so baa set to null.
