- Implement the aggregation and assembly service that tracks completion per request_id and triggers final PDF assembly.
- Expose and document the POST /api/generate endpoint and delivery interfaces (webhooks/SMTP) with strict input validation.
- Implement structured audit logging (Trace ID per request) meeting ISS-01-801 auditing requirements (AU-02 through AU-12).
- Participate in mandatory peer review and CI/CD, maintaining >80% automated test coverage.
Required Qualifications

- Preferred: async/event-driven design with AWS SQS/SNS and Celery or FastStream; Pydantic V2; structured logging.
- Preferred: disciplined engineering with Ruff, Black, mypy (strict), Bandit, and Pytest.
