# Goal-4 Execution Plan: Memory System v1

## Task Sequence

1. Goal-4-Task-1: Design memory interface (prerequisite for all other tasks) [COMPLETE]
2. Goal-4-Task-2: Implement core data structures (depends on Task-1) [COMPLETE]
3. Goal-4-Task-3: SQLite integration (depends on Task-2) [COMPLETE]
4. Goal-4-Task-4: Audit logging (depends on Task-1, can proceed in parallel) [COMPLETE]

    B --> D[Task-3: SQLite Integration]
```

## Quality Gates

1. Interface design must be reviewed by symphony-score
2. Data structures must pass security review
3. SQLite adapter must include encryption tests
4. Audit logs must meet security baseline requirements

## Risk Mitigation

- Early interface review to prevent rework
- Security validation at each stage
- Modular implementation to isolate dependencies
