What’s inside

## What the build takes.

1. ### The knowledge layer
   
   Teaching the system how your agency works, and keeping it current.
2. ### Reliability and judgment
   
   Answers you can trace to a source, with people on the decisions that matter.
3. ### Security and isolation
   
   Keeping every client’s work separate and access set by role.
4. ### The team to run it
   
   The roles a running system needs, grown from the people you have.

Where Signal78 comes in

### Everything in the guide is buildable. The decision is whether your team should carry it.

The work clients hire an agency for is the strategy, the creative and the relationships. Retrieval pipelines, evaluation and client-separation controls take hours away from that work.

Signal78 is the operating layer this guide describes, built for agencies by agency people. Your clients, case studies, pricing and positioning stay yours.
