# OptionGroup

object type

An option group — the PICK-SOURCE for option dimensions (a size run, a brand color palette), typed from the canned registry (color/size drive the spine tier defaults; custom groups feed descriptive attributes that never explode variants). Holds ordered OptionValue children (their parent). NO org selection ever. Referenced BY Style schemes at the spine.

## 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 (OP-…). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `OptionGroup` 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 an OptionGroup parentId === rootId. |
| `rootId` | [ID](/types/#scalars) `ID!` | The org-group family root. |
| `createdAt` | [String](/types/#scalars) `String!` | When the record was created, as a UTC timestamp. |
| `updatedAt` | [String](/types/#scalars) `String!` | When the record last changed, as a UTC timestamp. |
| `revisionNum` | [Int](/types/#scalars) `Int!` | How many times this record has been edited; the first save is 0. |
| `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. |
| `optionGroupType` | [OptionGroupType](/types/OptionGroupType/) `OptionGroupType!` | The pick-source kind — set at creation, IMMUTABLE thereafter. |
| `code` | [String](/types/#scalars) | Optional mutable merchant reference code; uniqueness NOT enforced (the code stance). |
| `defaultSizeRunId` | [ID](/types/#scalars) | The dimension DEFAULT SizeRun: the run a style over this group fills its matrix with when it names none of its own; the run must be ACTIVE and over THIS group; set by update only (a run must exist first), EXPLICIT-null-clearable; absent = no default. |
