Strategic scope
Architecture is documented as a chain of control and data movement points, not as isolated feature cards. Every edge in the chain has an owner and an invariant.
Trust boundaries
- Ingress boundary: request authentication and rate-limiting.
- Policy boundary: validation, entitlement checks, and transformation rules.
- Provisioning boundary: connector write operations and audit logging.
Recommended decision order
- Define protocol mapping and allowed attribute transforms.
- Validate idempotent behavior across repeated SCIM operations.
- Attach rollback checkpoints for each boundary stage.
Architecture entry points
Architectural guardrails
- Each stage in the graph must provide a deterministic output before the next stage starts.
- Connector outputs are immutable audit events tied to a request correlation ID.
- Policy decisions must fail closed when the runtime policy set is incomplete.
