The suffix is the canonical unpadded Base64URL encoding of exactly 33 octets: fixed current-v1 suite code 0x01 followed by all 32 octets of the SHA-256 Event digest. Regex validation is only lexical; receivers MUST decode, require 33 octets, require byte 0 == 0x01, canonical re-encode, and verify the full digest before use.

$ref #/$defs/scope_ref · $ref #/$defs/scope_refRequired producer-signed security scope. The closed union is ordinary existing realm, circle, or native sidecar scope plus the create-only realm_genesis exception. It enters proof.event_digest and E2EE AAD. Reducers independently derive the exact scope from schema-validated payload and accepted references; missing dependencies, nonexistent scope, realm_id mismatch, omitted sidecar_id, substituting circle for sidecar, or any unequal field is fail closed. Sidecar domain Event kinds remain Extension-owned; recognizing this native security shape does not make Kernel interpret the Sidecar reducer. Exact product targets remain inside recipient-visible ciphertext.
* actor_id · oneOf[2] · $ref ./common-ids.schema.json#/$defs/actor_id
Complete protocol identity for an Event author or Realm member: account carries the exact AccountId for every Station-hosted principal; service identifies a service acting as itself. The discriminator is validated against accepted registration and admission evidence; it never authorizes itself. Account and service are distinct, and no comparison may fall back to a bare principal_id. Agent and integration classification, provisioning, controller binding and credential authorization are independently verified facts, not identity variants. Account actors at different Stations MUST NOT share or inherit authority merely because their principal_id, DID controller or signing key matches, including membership, capability, RealmCommit-signing and recovery authority.

Required by ak.profile.applet_* when the Event is introduced by an Applet, Ghost Actor, bridge, or delegated applet path. Enters canonical event bytes and therefore is covered by proof.event_digest. When present, authorization_ref MUST also be present and resolve to a real active registration/capability grant binding this applet_id, registration_epoch, action and resource per zh/extensions/applet-integration.md sections 4, 8 and 11. Service-actor self-signature proves provenance but is not an authorization substitute. Capability-gated actions require a grant covering action/resource. For subject_only operations the referenced grant binds only the exact active install and cannot replace the subject signature, FSM or independent action authority. Service self-authored Events use ActorId.service; the install grant subject MUST be the same exact ActorId.service as its producer; hosting Station and effective scope are verified separately without coercing a Service into an account variant.

^ak:realm:[A-Za-z0-9_-]{44}$* scope_ref ·
$ref #/$defs/scope_ref · $ref #/$defs/scope_refRequired producer-signed security scope. The closed union is ordinary existing realm, circle, or native sidecar scope plus the create-only realm_genesis exception. It enters proof.event_digest and E2EE AAD. Reducers independently derive the exact scope from schema-validated payload and accepted references; missing dependencies, nonexistent scope, realm_id mismatch, omitted sidecar_id, substituting circle for sidecar, or any unequal field is fail closed. Sidecar domain Event kinds remain Extension-owned; recognizing this native security shape does not make Kernel interpret the Sidecar reducer. Exact product targets remain inside recipient-visible ciphertext.
* actor_id · oneOf[2] · $ref ./common-ids.schema.json#/$defs/actor_id
Complete protocol identity for an Event author or Realm member: account carries the exact AccountId for every Station-hosted principal; service identifies a service acting as itself. The discriminator is validated against accepted registration and admission evidence; it never authorizes itself. Account and service are distinct, and no comparison may fall back to a bare principal_id. Agent and integration classification, provisioning, controller binding and credential authorization are independently verified facts, not identity variants. Account actors at different Stations MUST NOT share or inherit authority merely because their principal_id, DID controller or signing key matches, including membership, capability, RealmCommit-signing and recovery authority.

authorization_ref · oneOf[6]
Optional. Required when executed_by is present. It identifies an accepted Grant, delegation Event, DID-document delegation, or one of the closed profile-specific authority constants. The current governance Station evaluates the reference against the target stream's committed state.

$ref #/$defs/applet_id · $ref #/$defs/applet_idOptional signed Applet provenance. Required by ak.profile.applet_* when the Event is introduced by an Applet, Ghost Actor, bridge, or delegated applet path. Enters canonical event bytes and therefore is covered by proof.event_digest. When present, authorization_ref MUST also be present and resolve to a real active registration/capability grant binding this applet_id, registration_epoch, action and resource per zh/extensions/applet-integration.md sections 4, 8 and 11. Service-actor self-signature proves provenance but is not an authorization substitute. Capability-gated actions require a grant covering action/resource. For subject_only operations the referenced grant binds only the exact active install and cannot replace the subject signature, FSM or independent action authority. Service self-authored Events use ActorId.service; the install grant subject MUST be the same exact ActorId.service as its producer; hosting Station and effective scope are verified separately without coercing a Service into an account variant.
external_ref ·
$ref #/$defs/external_ref · $ref #/$defs/external_refOptional signed external provenance reference for Applet / bridge-originated Events. It is covered by event_digest and MUST NOT be carried only in unsigned when used for loop prevention, audit, or external-message idempotency. Must not contain unauthorized external plaintext.

$ref #/$defs/canonical_event_timestamp · $ref #/$defs/canonical_event_timestampsemantic_refs · array<$ref #/$defs/semantic_ref>
Optional semantic refs with role. Omit when there are no semantic references; an explicitly empty array is not canonical. Admission selectors determine any required references. PCR policy recovery has no DID-root anchor reference; its policy/session/replacement-key authority is verified separately.

oneOf · oneOf[3] · object
Genesis scope for ak.realm.create only. It carries no realm_id because the receiver derives every Realm id, including Collaboration, Direct Conversation, human PCR, and Agent PCR, as retype(event_id, "realm") from this create Event (zh/models/realm-and-space.md section 2.5.0). The uniform omission also prevents the digest cycle.

The suffix is the canonical unpadded Base64URL encoding of exactly 33 octets: fixed current-v1 suite code 0x01 followed by all 32 octets of the SHA-256 Event digest. Regex validation is only lexical; receivers MUST decode, require 33 octets, require byte 0 == 0x01, canonical re-encode, and verify the full digest before use. Other registered digest suites remain available only to the typed domains that explicitly select them and MUST NOT appear in Event IDs.
