 - every field that is not `is required` gets `@IsOptional()` before the type decorator
 - every generated DTO imports from `'class-validator'`
 
-## Shared Enum Files
+## Shared Types
 
-Enums referenced by DTOs across multiple modules MUST be generated as standalone files at:
+Shared TypeScript types are generated by the `shared-types` stage BEFORE
+`nest-entities` runs. Per-entity modules MUST import them; they must NEVER
+redefine them.
 
-```
-server/src/enums/<EnumName>.enum.ts
-```
+Zones:
 
-Example for `EquipmentStatus`:
-```ts
-// server/src/enums/equipment-status.enum.ts
-export enum EquipmentStatus {
-  Active = 'Active',
-  Repair = 'Repair',
-  Reserve = 'Reserve',
-  WriteOff = 'WriteOff',
-}
-```
+- `server/src/enums/<kebab-enum-name>.enum.ts` — one file per DSL enum
+- `server/src/shared/pagination.ts` — `PaginatedResponse<T>` and `ListQueryParams`
+- `server/src/shared/index.ts` — barrel for shared types
 
-DTO files import the enum with path `../../enums/<enum-name>.enum` (two levels up from `modules/<kebab>/dto/`):
-```ts
-import { EquipmentStatus } from '../../enums/equipment-status.enum';
-```
+Import conventions depend on the importing file's depth:
 
-Do NOT inline enum values into DTOs. Do NOT put enum files inside the module folder.
+- From a module/controller/service file at `server/src/modules/<kebab>/<file>.ts`:
+  ```ts
+  import { EquipmentStatus } from '../../enums/equipment-status.enum';
+  import { PaginatedResponse, ListQueryParams } from '../../shared/pagination';
+  ```
+
+- From a DTO file at `server/src/modules/<kebab>/dto/<file>.ts` (one level deeper):
+  ```ts
+  import { EquipmentStatus } from '../../../enums/equipment-status.enum';
+  import { PaginatedResponse, ListQueryParams } from '../../../shared/pagination';
+  ```
+
+Enum-typed DTO fields MUST be declared with the actual enum type, NOT
+`string`. The enum is imported from the shared file above. `@IsEnum(EnumName)`
+still applies at runtime for validation. Because the DTO type matches the
+Prisma-generated enum type by name and by string values, service code can
+pass DTOs into Prisma without `as EnumName` casts.
