# SalePrice

object type

A sale price: ONE effective-dated price window in the parent InventoryItem schedule — the dated record-set IS the full price history. Windows are half-open \[startAt, endAt) with endAt ALWAYS present (far-future = the standing price); past the last endAt with no successor the item is NOT for sale (the LAPSE rule — enforced by the sell path; stores + normalizes). Inserts are splice-normalized: a start falling STRICTLY inside the immediately-preceding window auto-TRIMS that predecessor endAt to the new start (the ONE sanctioned in-place mutation — revisioned + evented); overlap with ANY OTHER record refuses CONFLICT/PRICE_WINDOW_OVERLAP naming the blockers. No past starts. The schedule currency is FIXED by the FIRST record; a mismatch is refused NAMED. Doom cancels a not-yet-effective FUTURE record only. startAt/endAt/price are wire-IMMUTABLE.

## 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 (SP-…). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `SalePrice` 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 \| doomed. |
| `parentId` | [ID](/types/#scalars) `ID!` | The parent InventoryItem; for a SalePrice 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. |
| `startAt` | [String](/types/#scalars) `String!` | The window start (INCLUSIVE; UTC ISO-8601) — set at birth (absent in the create input = effective NOW, server-stamped), IMMUTABLE thereafter. |
| `endAt` | [String](/types/#scalars) `String!` | The window end (EXCLUSIVE; UTC ISO-8601; ALWAYS present). Moves ONLY via the system splice trim when a successor starts inside this window. |
| `price` | [MoneyEntry](/types/MoneyEntry/) `MoneyEntry!` | The selling price for the window (the strict decimal-string money grammar; the schedule currency is FIXED by the FIRST record). IMMUTABLE — supersede to change. |
| `markdownPlanId` | [ID](/types/#scalars) | The MarkdownPlan whose schedule fan-out wrote this window. |
| `markdownStepIndex` | [Int](/types/#scalars) | The 0-based step within the stamping plan's cadence. |
