A governance-enforced ceiling on the number of sequential re-delegations of authority that may occur within an agent hierarchy before further delegation is prohibited, preventing unbounded chain growth that could obscure accountability. The depth limit is expressed as a non-negative integer encoded in the root delegation credential and decremented by each downstream delegator. An agent receiving a credential with a depth limit of zero may exercise the granted authority but may not delegate it further.

The mandatory reduction in granted permissions when an agent re-delegates authority to a subordinate agent, ensuring that delegated capabilities can never exceed the scope possessed by the delegating agent at the time of delegation. Attenuation is enforced by the credential issuance infrastructure and verified by receiving agents before accepting any delegation. Attempted scope expansion during re-delegation is detected and rejected as a policy violation.

A verifiable, ordered collection of cryptographically linked delegation credentials tracing the transfer of authority from a root principal to the currently acting agent, enabling any relying party to independently verify the legitimacy of the agent's claimed permissions. Each link in the chain references its predecessor by credential identifier and signature, creating a tamper-evident sequence. Chain verification algorithms must confirm signature validity, scope consistency, and depth limit compliance at every link.

The mechanism by which trust assertions established at the root of an agent hierarchy are transmitted downward through delegation relationships, with each level inheriting a subset of the trust properties of its parent. Trust propagation rules specify which trust attributes are inheritable, which require independent re-establishment at each level, and which are strictly local to the granting entity. Propagated trust does not imply equivalence with the root trust level but rather a bounded derivative.

A short-lived, cryptographically signed authorization object issued by a delegating agent to a subordinate that precisely encodes the subset of capabilities being transferred, together with temporal and contextual constraints on their exercise. The token is consumed by the receiving agent's authorization module to gate access to specific operations and expires automatically when the encoded time window elapses. Token issuance events are logged to the delegating agent's audit record.

An authority reserved by a principal at any level of a delegation hierarchy to revoke, modify, or supersede the delegated permissions of any subordinate agent within its chain, effective immediately upon notification or at a scheduled future time. Override rights are encoded in the root delegation credential and propagated with each re-delegation, ensuring that no downstream agent can disclaim their subordination to the override. Activation of a supervisory override is a governed action logged with full provenance.

The automatic invalidation of all downstream delegation credentials when a delegation at any level of a hierarchy is revoked, ensuring that agents holding derivative authority cannot continue to operate after the principal chain is broken. Cascade revocation is propagated through the delegation registry and enforced by the authorization modules of all affected agents. The cascade event is recorded as a governance action with the triggering revocation as its root cause.

The design principle mandating that each agent in a delegation hierarchy is granted only the specific permissions required to complete its assigned tasks, with no residual authority beyond that scope, minimizing the blast radius of compromise or misbehavior. Applying this principle requires that delegating agents analyze task requirements before issuing delegation credentials and refrain from convenience-driven over-provisioning. Compliance audits evaluate whether issued delegations satisfy this constraint by comparing granted scope against observed task requirements.

The extension of agent delegation chains across administrative domain boundaries, enabling an agent under the governance of one organization to act with scoped authority on behalf of a principal in a different organization, subject to bilateral trust agreements. Cross-organizational delegation credentials must carry explicit boundary markers and are subject to additional policy constraints imposed by the receiving organization. Both organizations retain independent revocation authority within their respective domains.

A tamper-evident log recording every issuance, acceptance, exercise, modification, and revocation of delegation credentials within an agent hierarchy, timestamped and signed by the acting parties to provide a complete accountability record. The audit trail is maintained independently of the agents themselves to prevent self-serving modification. Regulatory and compliance processes consume the audit trail to verify that delegation practices conformed to policy throughout the observed period.

The runtime transfer of a delegation credential from one agent to another without interrupting the associated workflow, triggered by performance monitoring, agent failure detection, or governance decision. Reassignment preserves the original scope and depth constraints and updates the delegation registry to reflect the new holder. All actions taken under the reassigned credential after transfer are attributed to the new holder, with the transfer event logged for chain continuity.

A time-bound restriction encoded in a delegation credential that limits the validity period of the granted authority to a specific window defined by absolute timestamps or relative duration from issuance. Agents are required to verify temporal constraints before exercising delegated authority and must cease using a credential upon expiry without requiring explicit revocation. Expired credentials are retained in the audit trail but are rejected by authorization modules that enforce freshness checks.

A directed acyclic graph representation of the capability relationships across an agent delegation hierarchy, where each node represents an agent and each directed edge represents a delegation relationship with its associated scope and depth metadata. The graph enables visual and algorithmic analysis of authority distribution, identification of over-privileged agents, and simulation of cascading revocation impacts. Graph integrity is maintained by the delegation registry and recomputed upon each credential issuance or revocation.

A reusable, parameterized specification that defines the allowable scope, depth limits, temporal constraints, and revocation conditions for a class of delegation relationships within an organization's agent governance framework. Templates are approved through the governance process and instantiated at runtime with specific parameter values to produce individual delegation credentials. Using templates reduces policy drift and ensures that commonly used delegation patterns remain aligned with organizational security objectives.

The governance principle establishing that the originating human or organizational entity at the apex of a delegation hierarchy retains ultimate responsibility for all actions taken by agents operating under delegated authority derived from the root, regardless of the delegation depth at which those actions occurred. This principle prevents accountability dilution through deep delegation chains and requires root principals to implement monitoring commensurate with the breadth of authority they delegate. Accountability records link every downstream action to the root principal through the delegation chain proof.
