A directed acyclic graph representing the permission propagation relationships across an agent deployment, where each node corresponds to an agent or principal and each directed edge encodes the scope subset inherited from the parent node, enabling visualization and algorithmic analysis of the full permission landscape. The graph is maintained by the delegation registry and recomputed whenever a delegation credential is issued, modified, or revoked. Graph analysis identifies permission concentration, inheritance bottlenecks, and potential scope escalation pathways.

A formally specified constraint governing how a specific permission class is transmitted through delegation relationships, including whether it is inheritable at all, whether it must be attenuated at each level, and whether it carries additional conditions when propagated to agents beyond a defined delegation depth. Propagation rules are maintained in the governance policy and enforced by the credential issuance infrastructure to ensure consistency across all delegation events. Permissions without explicit propagation rules default to non-inheritable under the minimum necessary authority principle.

The maximum set of permissions an agent may hold as a result of scope inheritance from its delegation chain, computed by applying all applicable propagation rules and attenuation requirements to the root permission grant, establishing an absolute upper bound that the agent's policy enforcement layer cannot exceed regardless of subsequent instructions. Inherited scope ceilings are computed at binding time and cached securely in the agent's authorization module. Runtime instructions that would require the agent to act above its inherited scope ceiling are blocked by the policy enforcement layer.

A condition arising when an agent holds membership in multiple delegation chains that grant overlapping but inconsistent permissions for the same operation class, requiring a conflict resolution mechanism to determine which chain's scope terms govern the disputed permission. Scope inheritance conflicts are identified by the delegation registry at the time competing chain memberships are registered and classified by severity before the agent enters operation. Resolution procedures apply the more restrictive permission set by default, with explicit override requiring principal agreement from all conflicting chains.

A governed runtime mechanism enabling the modification of an agent's active permission set in response to changing operational conditions — such as task completion, context transitions, or security alerts — without requiring full credential reissuance or agent restart. Dynamic adjustments are authorized by the mandate issuance authority and transmitted to the agent's policy enforcement layer as signed scope delta messages. All dynamic adjustments are logged with the authorizing principal, the triggering condition, and the resulting permission delta.

A transformation applied during scope inheritance that reduces a complex permission grant to a semantically equivalent but more efficiently represented form, minimizing the computational overhead of permission evaluation during high-frequency authorization checks without losing any constraint information. Compression operators are defined for each permission class and their output must be verifiably equivalent to the expanded form. Compressed scope representations are annotated with the operator identifier to enable decompression when full permission detail is required.

A dedicated log tracking every exercise, assertion, and modification of inherited permissions by an agent, capturing the specific permission invoked, the delegation chain link that provided it, the operation authorized, and the outcome, providing a complete accountability record of how inherited authority was used. The audit trail is maintained separately from the general agent activity log to support targeted permission abuse investigations. Retention and access policies for the inherited permission audit trail are defined in the governance charter and may exceed standard log retention periods.

The automated identification of agent behaviors that attempt to exceed the inherited scope ceiling through indirect means — such as chaining together individually permitted operations to achieve a collectively prohibited outcome — distinguishing unauthorized capability accumulation from legitimate multi-step task execution. Detection algorithms model the composite permission effect of planned action sequences and flag patterns whose aggregate effect exceeds the inherited scope ceiling. Detected escalation attempts are blocked and reported to the governance system as potential security incidents.

A governance action that halts all further propagation of a specific permission class through the delegation network, preventing new agents from inheriting the frozen permission while allowing existing holders to retain it under enhanced monitoring, used as a rapid response to the discovery of a permission class that poses unexpected risk. Freezes are time-limited and require governance review before either being lifted or converted to a permanent propagation rule change. All freeze events are published to the scope inheritance governance register.

A cryptographically signed claim issued by the delegation registry confirming the complete permission set inherited by a specific agent through all active delegation chains, enabling relying systems to verify the agent's authority claims without independently traversing and verifying the full inheritance graph. Attestations are time-bounded and must be refreshed before expiry to prevent stale authority claims. They reference the current state of the scope inheritance graph at the time of issuance, enabling verifiers to detect changes that may have occurred since attestation.

The selective enablement of inherited permissions based on the agent's current operational context — such as network zone, data classification, or task type — where the full inherited scope ceiling is never fully active simultaneously but different subsets are activated as the agent moves between authorized contexts. Contextual activation reduces the instantaneous attack surface by ensuring that sensitive permissions are inactive when not operationally required. The activation rules are defined in the mandature's operational context binding and enforced by the policy enforcement layer.

A periodic governance document summarizing the distribution of inherited permissions across the agent fleet, identifying agents with unusually broad scope, permission classes with high inheritance depth, and any scope inheritance conflicts or freezes active during the reporting period. The report is produced by the delegation registry and reviewed by the mandate issuance authority to identify systemic permission over-provisioning before it manifests as security incidents. Report findings inform updates to permission propagation rules and mandate templates.

A risk assessment technique that applies a trust discount factor to inherited permissions based on their delegation depth, reducing the effective weight given to deeply inherited authority claims during authorization decisions to reflect the increased uncertainty and accountability diffusion associated with long delegation chains. Weighting parameters are defined in the governance policy and calibrated by analyzing historical patterns of permission abuse by delegation depth across the agent fleet. High-risk operations require inherited permissions to clear a minimum trust weight threshold before authorization is granted.

The elapsed time between the revocation of a delegation credential and the corresponding update of all downstream agents' active permission sets to reflect the removal of inherited permissions that depended on the revoked credential. Minimizing propagation latency is a critical security objective because the latency window represents a period during which agents may exercise permissions they are no longer authorized to hold. Governance policies specify maximum acceptable latency thresholds for different permission risk levels and require technical controls to meet those thresholds.

The centralized or distributed software component responsible for computing, enforcing, and auditing scope inheritance rules across the agent fleet, consuming delegation registry state, permission propagation rules, contextual scope activation policies, and dynamic scope adjustments to produce authoritative, real-time permission sets for each active agent. The policy engine exposes a decision point interface consumed by agent runtime environments and a management interface consumed by governance administrators. Its decisions are logged with full justification trails to support post-hoc authorization audits.
