# Contact

object type

A contact — the UNIFIED, REUSABLE contact-info master: one group-scoped record holding an optional PERSON block and/or an optional INLINE address block (at-least-one-of — an empty contact is refused at the boundary), attached to hosts via role-tagged ContactAssignments. Group-scoped like a Brand (parent = the org group). Carries EXTERNAL-party + functional addresses ONLY — the PhysicalFacilityLocation stays the SOLE physical-address holder for OUR facilities (the PFL fence). Deactivate AND doom are BOTH blocked by live (active) assignments.

## Fields

| Field | Type | Notes |
| --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it. |
| `sysId` | [String](/types/#scalars) `String!` | The group-scoped human-facing system id (CO-…). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `Contact` here. |
| `caption` | [String](/types/#scalars) `String!` | The record’s display name — what people see it called. |
| `status` | [String](/types/#scalars) `String!` | The FSM state: active \| inactive \| doomed. |
| `parentId` | [ID](/types/#scalars) `ID!` | The parent org group; for a Contact parentId === rootId. |
| `rootId` | [ID](/types/#scalars) `ID!` | The org-group family root. |

| `revision` | [ID](/types/#scalars) `ID!` | The OCC revision token — supply it on every mutation of this record; rotates on every write. |
| `refCaptions` | [RefCaption](/types/RefCaption/) `[RefCaption!]!` | The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption. |

| `address` | [ContactAddress](/types/ContactAddress/) | The optional inline address block; absent on a person-only contact. |
