Message templates
Template catalogs, review, and unit classes - separate from channel Live badges.
Template unit class on debit rows
Every prepaid debit row must carry a named unit class — template, session, segment, or verify — so finance can join spend without folklore spreadsheets.
Template catalog ops at volume
Operate versioning, named owners, and retire rules when many templates are Live — one catalog rhythm product and finance can open without hero threads.
Template reject: no silent fallback burn
Fail path: a rejected template must stop the send — no silent SMS or session burn without a named fallback policy product and finance can audit.
Template review gate and unit class
Gate template review and map unit class before prepaid debit at volume — Approved plus named unit, or no production send.
Template catalog before channel Live
Buyer path: approved templates must exist before any Live badge on rich or SMS message classes — catalog first, volume talk later.
