Known users and service principals
Authentication establishes the actor before project information or actions become available.
Security model
Give every action an identity, boundary, and record
SDD combines role-based access, server-side authorization, accountable agent actions, audit events, and deployment boundaries.
Connected tools operate through governed entry points so project context can be used without turning access into invisible authority.
Control layers
Authority remains explicit from screen to service
Security is carried through identity, project membership, application policy, integration credentials, and durable audit context.
Role and workspace boundaries
Owner, Admin, Developer, QA, Auditor, and Viewer responsibilities are enforced at UI and server boundaries.
Scoped external credentials
Connected systems use controlled account and project associations rather than duplicated secrets in page settings.
Auditable changes and actions
Lifecycle transitions, external synchronization, and agent operations retain actor, source, target, and outcome.
Governed automation
Context does not imply permission
Authenticated actor→Authorized tool→Validated change→Audit outcome
Deployment boundaries
Match the operating model to the organization
Application controls
Server-side authorization, workspace membership, and auditable operations protect controlled actions.
Enterprise integration
API, webhook, and optional mTLS controls support hardened system-to-system communication.
Isolated operation
Dedicated infrastructure and data boundaries support organizations with stricter residency and operational constraints.
