Credential boundaries
Control credentials use the Control API. World credentials use the HTTP, MCP, or
wire endpoint in the binding. Never pass a control credential, callback signing
key, or storage URL to the agent being evaluated.
Project authorization
Organization membership and project access are separate. Project roles areviewer, builder, and manager, expanded by the server into explicit actions.
Developer and service credentials can narrow those actions further and may be
restricted to one project.
Every read or mutation is authorized against the selected organization and project.
Resource IDs alone do not grant access.
Isolated worlds
Each session is pinned to one project, build, environment, seed, and lease. World access includes an actor ID and explicit Tool-operation capabilities. Reset and fork remain inside the selected project and exact build lineage. Your runner retains the customer agent’s model-provider credentials and performs the interaction. Do not put those credentials in world source or bindings.Tool trust
Repository or uploaded builds may introduce executable Tool behavior. The platform records exact Tool artifacts and requires explicit project approval before newly introduced private artifacts can execute. Deprecation prevents new selection; revocation blocks affected execution paths. Tool declarations, apps, and fidelity claims are package-owned. Approval means the exact artifact may run in the project; it does not certify that it perfectly replicates an external service.Evidence and captures
Evidence access follows project grants and exact share decisions. Retention policy applies to new runs. Deletion and export are explicit, auditable operations. Optional captures can contain application output or personal data; redact secrets before upload and retain only what a drill needs. Run evidence can carry a verification manifest and platform attestation. A user-produced report uploaded for storage remains marked user-produced and unattested.Operational safeguards
- Unsafe writes require idempotency keys and optimistic concurrency where needed.
- Long-running work returns an operation that can be polled after a timeout.
- Audit history records organization and project changes.
- Callback receivers require explicit registration and approval; signing material is revealed only through its dedicated control path.
- API errors include a correlation ID and whether the caller may retry.
