sent-routing-strategist

Decides how a Sent message should reach the recipient — automatic routing versus a pinned channel, what the channel array actually does, how fallback and reroute work, and why a message ended as FAILED, FILTERED, BLOCKED, or channel "auto". Use when choosing the channel field, expecting WhatsApp-to-SMS fallback, debugging an unexpected route or duplicate charges from multiple channels, or interpreting message status and activity evidence.
