# Season

object type

A season — a merchandising-calendar building block; an INSTANCE, not a recurring pattern. Master data ONLY: the merchandising lifecycle (planning → buying → selling → clearance) belongs to future process constructs that reference it — the optional selling window is reporting data, never an FSM trigger. Per-org enablement (OrgSeason) arrives; Product↔Season references 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 (SN-…). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `Season` 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 Season 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. |
| `code` | [String](/types/#scalars) | Optional mutable merchant reference code, e.g.; uniqueness NOT enforced (the code stance). |
| `startAt` | [String](/types/#scalars) | Optional selling-window start (UTC ISO-8601) — reporting data, never an FSM trigger. |
| `endAt` | [String](/types/#scalars) | Optional selling-window end (UTC ISO-8601); startAt ≤ endAt when both present. |
