Pull request overview
Updates the Low Code data modeling documentation to clarify how primitive collection storageKey values are created and how clients should handle them when creating collections via tooling APIs.
Changes:
- Clarifies that primitive collection
storageKeyis a stable internal identity stored in the model. - Documents that Designer and MCP “add collection” mutations must omit
storageKeybecause the server generates it.
💡 Add a code-review agent skill or configure MCP servers for context-aware, tailored reviews. Learn more in the docs.

| * The effective item limit is the lower of `maxCount` and `LowCode:PrimitiveCollections:MaximumItemsPerProperty`. The verified global default is `1000`. | ||
| * `storageKey` is a stable internal identity used by the normalized collection table. Let the Designer generate it and do not change it after data exists. | ||
| * `storageKey` is a stable internal identity stored in the model for the normalized collection table. When adding a collection through the Designer or MCP, omit it from the mutation payload; the server generates it. Do not change it after data exists. |
