## Working standards
- AWS and Linux work is scoped around availability, security, monitoring, backups and handover.
- Email infrastructure is limited to transactional messages and permission-based audiences.
- Purchased or scraped lists, phishing, deceptive sender identities and filter bypassing are not supported.
- Inbox placement is never guaranteed; recommendations focus on consent, authentication, feedback and reputation signals.
