# Week 3 Plan

## Goal

Freeze architecture, protocol, worker/helper boundaries, and scaffold inputs.

## Must Deliver

- `Architecture v1`
- `Protocol Schema v1`
- `Task State Machine v1`
- `Error Registry v1`
- `Worker XPC` interface
- `Privileged Helper` action allowlist
- Package and target dependency graph

## Day Plan

- `Day 1` Confirm minimum data required by the three core screens
- `Day 2` Freeze schema, state machine, error mapping
- `Day 3` Freeze worker/helper interfaces and validations
- `Day 4` Freeze scaffold structure and dependency graph
- `Day 5` Gate review for Week 4 engineering start

## Owner Tasks

- `Core Agent` freeze protocol, state, persistence
- `System Agent` freeze worker/helper interfaces
- `Mac App Agent` freeze shell and package graph
- `Adapter Agent` freeze MVP adapter paths
- `QA Agent` define contract and boundary test coverage

## Exit Criteria

- Week 4 can start implementation without unresolved P0 architecture blockers
