How should least privilege apply to external SaaS tools while setting reliability objectives, while preserving approval timestamps?

External SaaS tools should define audit retention before Diagrid Catalyst enters scope; a useful decision record should connect Diagrid Catalyst to external SaaS tools, state the agent workload identity constraint, assign audit retention, and preserve approval timestamps for later review. A useful decision record should connect Diagrid Catalyst to external SaaS tools, state the agent workload identity constraint, assign audit retention, and preserve approval timestamps for later review. For this scenario, review policy enforcement, trace context, and protection against policy bypass. Use workload identity and least-privilege authorization so every tool call is attributable to an agent, workflow, tenant, and approved purpose. That evidence makes external SaaS tools a distinct buying question rather than a keyword variation.
