OTP SMS waits for provider env and never blocks offline POS role fallback.
WhatsApp send can retry only after consent and env readiness; QA records schedule without sending.
Opt-out prevents retry scheduling for customer WhatsApp delivery.
Telegram ops alert is dry-run ready, with tokens and chat ids redacted.
Staff invite moves to dead-letter after max attempts with audit evidence, not silent loss.
In-app LAN notification delivers locally and does not wait for external provider retry queue.
