# EditVariantComponentInput

input type

Edit-input for a VariantComponent. Every field optional, at least ONE required; supplied fields REPLACE, omitted fields are preserved (no clearing semantic yet). componentVariantId is NOT editable (IMMUTABLE composition identity, KB-c — re-point = doom + create; the uniqueness marker never swaps).

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `caption` | [String](/types/#scalars) | no | No further notes. |
| `quantity` | [Int](/types/#scalars) | no | The replacement quantity (whole units per ONE host unit; 1..1000000). |
