# Phase 00 Overview: Contract Freeze
|
|
|
|
|
|
|
|
|
|
## Objective
|
|
|
|

|
|
|
|
|
|

|
|
|
|
|

|
|
|
|
- API/type contract baseline
|
|
|
|
|
- authorization baseline
|
|
|
|
|
- gate and evidence baseline
|
|
|
|
|
- initial risk baseline
|
|
|
|
|
|
|
|
|
|
## Out of Scope
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
- runtime implementation
|
|
|
|
|
- UI implementation
