61. consent_check: is the opt-in express and channel-specific? (Web-form email consent ≠ SMS consent.) Required elements: frequency disclosure, STOP/HELP language, terms link. [COMPLIANCE REVIEW] flags for TCPA/CASL-equivalent exposure.
72. program_design: per use case — trigger, message (≤160 chars for SMS, personalization beyond first-name), send-window rules (local time, no early/late sends), and frequency cap across ALL use cases combined (the cap is the program).
83. messages: drafted, each passing the "would a friend send this?" bar — transactional tone, one link max, no ALL CAPS urgency.
94. escape_valves: instant STOP honoring, preference downgrade option (monthly-only), and the quiet-hours rule.
105. whatsapp_note: template pre-approval requirement and session vs. template message logic.
