Struct Entity 

pub struct Entity {

    pub id: Uuid,
    pub namespace: String,
    pub kind: String,
    pub entity_type: Option<String>,
    pub name: String,
    pub description: Option<String>,
    pub properties: Option<Value>,
    pub tags: Vec<String>,
    pub created_at: i64,
    pub updated_at: i64,

    pub merged_into: Option<Uuid>,
    pub merge_event_id: Option<Uuid>,
    pub content_ref: Option<String>,
}

Storage-level entity record. Flat SQL-friendly representation. Maps to the entities substrate table.

Fields

id: Uuid

namespace: String

kind: String

entity_type: Option<String>

Pack-governed subtype token. Maps to entities.entity_type column.

name: String

description: Option<String>

properties: Option<Value>

tags: Vec<String>

created_at: i64

updated_at: i64

deleted_at: Option<i64>

merged_into: Option<Uuid>

When this entity was tombstoned by a merge, the into entity’s ID.

merge_event_id: Option<Uuid>

Opaque event ID for the merge that tombstoned this entity.

content_ref: Option<String>

Read-only compatibility projection of attachment role "content".

Entity writes ignore this field. Callers publish content through the attachment substrate; reads populate it so existing response payloads keep their content_ref field during the coordinated cutover.
