Module models 

Serde-derived types for AAE protocol schemas.

Structs

AuditEvent

A single hash-chained audit log record.

CapabilityScope

Capability token scope.

CapabilityToken

Capability token claims (signed externally as JWT/PASETO/biscuit).

Confidence

v0.7: the standard ext.confidence shape on policy decisions.

Context

Context fields on a proposal. Open shape; rationale is required.

CostEstimate

v0.3: the standard ext.cost_estimate shape in step previews.

Effect

A predicted effect of executing a step.

EventSignature

Optional digital signature on an audit event.

PolicyDecision

Output of policy engine evaluation.

Preview

Predicted effects of executing a proposal.

Proposal

A typed plan submitted by an agent.

Step

A single tool invocation within a proposal.

StepPreview

Preview output for a single step.

ToolRegistration

Tool registration declaring the tool’s plan/preview contract.

Enums

BlastRadius

Blast radius classification for proposed effects.

Decision

Policy engine decision values.

Reversibility

v0.3: whether a tool’s effects can be undone.

Constants

EVENT_TYPE_ARTIFACT_ATTESTED

Event type binding an out-of-chain artifact to a chain event by content hash (v0.8). Required payload fields: artifact_hash (algorithm-prefixed canonical hash), bound_event_id, artifact_kind (free-form string, e.g. legible_record, session_recording). Artifacts are advisory; the chain event is authoritative.

STRICTNESS_STRICT_LITERAL

Core strictness mode: gateway executes exactly the approved steps in order; deviation aborts. This is the REQUIRED default (SPEC §5.3).

STRICTNESS_STRICT_TEMPLATE

Core strictness mode: gateway executes steps matching templates with parameter substitution (SPEC §5.3, OPTIONAL).
