This docs page is the operator-friendly overview.

## Primary objective

Build an internal WhatsApp control plane that replaces Charles in our stack with:

* drop-in compatibility where useful
* a complete inbox and operator workflow
* durable ownership of messaging state
* explicit webhook, audit, and replay tooling
* forward-only migration support

## Core pillars

* provider runtime
* contacts and subscriber state
* inbox
* templates
* campaigns
* journeys
* integrations
* admin and diagnostics

## Delivery model

The platform is being built in reviewable slices:

1. repo/bootstrap
2. data and auth foundations
3. provider ingress and dispatch
4. compatibility surfaces
5. inbox
6. templates, contacts, and audiences
7. campaigns
8. journeys
9. migration and hardening
