The next move should be A first, but expanded into a trust gate, not just a visual QA pass. Staff confidence depends on the panel proving that every communication shown or started from a Matter is related to that Matter and will be logged. After that gate passes, build C and B together as a Matter communications command surface.
If we make the phone number clickable before proving logging and Matter matching, the UI may look easy but still feel risky. If we add notifications before proving the inbound source and unread state, staff may mistrust the badge. The better path is to prove the data/logging truth first, then make the actions and notifications obvious.
The Matter tab should feel like a communication cockpit for that Matter. The top shows the active contact context. The default view shows recent Matter communications and summaries. Call, SMS, History, and Templates become task modes. Templates should live under SMS, not as a free-floating unrelated button. Related people should be selectable from the same area so staff can call or text the client, adjuster, or other linked people without hunting through the page.
Continue from the deployed contact-header cleanup. Preserve SMS Magic history and rollback safety. Do not delete SMS Magic records, uninstall the package, or disable automation. Treat RingCentral as the live action surface and Litify Notes/history as the durable record trail. The next agent should start with read-only live validation where possible, then implement the Matter-scoped communication surface only after the trust gate confirms the fields, objects, and logging behavior.
