ref: https://github.com/medusajs/medusa/pull/14189
**Summary**
This PR extends the translation module to support automatic translation syncing for cart line items based on the cart's locale.
Key changes:
- Added locale field to the Cart model to store the cart's locale preference
- Created new workflow steps:
- getTranslatedLineItemsStep - Translates line items when adding to cart or creating a cart
- updateCartItemsTranslationsStep - Re-translates all cart items when the cart's locale changes
- Integrated translation logic into cart workflows:
- createCartWorkflow - Applies translations to initial line items
- addToCartWorkflow - Applies translations when adding new items
- updateCartWorkflow - Re-translates all items when locale_code is updated
- refreshCartItemsWorkflow - Maintains translations during cart refresh
- Added applyTranslationsToItems utility to map variant/product/type/collection translations to line item fields (title, subtitle, description, etc.)
Fixes#13735
### What
This Pull Request introduces new database migrations to remove multiple redundant indexes across several core modules, including product, cart, order, customer, and inventory.
### Why
As detailed in issue #13735, a fresh Medusa installation produces numerous "Duplicate Index" warnings. These legacy indexes add unnecessary write overhead and provide no performance benefit. This PR cleans up the schema to resolve these warnings and improve database health.
### How
I have added one new, reversible migration file for each of the five affected modules:
- `@medusajs/product`
- `@medusajs/cart`
- `@medusajs/order`
- `@medusajs/customer`
- `@medusajs/inventory`
Each migration's `up()` method safely drops the older, redundant index, and its `down()` method re-creates it, ensuring the change is fully reversible and non-destructive.
### Testing
I have tested these migrations by following the local development workflow outlined in the `CONTRIBUTING.md` guide.
1. **Setup:**
* Cloned my forked Medusa repository locally .
* Created a separate, fresh test project using `npx create-medusa-app@latest my-medusa-store`.
* The test project's PostgreSQL database, which already contained the schema with the duplicate indexes.
2. **Linking Local Source Code:**
* In the test project's `package.json`, I modified all `@medusajs/*` dependencies and resolutions to point to the local packages in my forked repository (e.g., `"@medusajs/product": "file:../medusa/packages/modules/product"`).
* From the test project's directory, I ran `yarn install` to link the local, modified Medusa source code into its `node_modules`.
3. **Build & Migration:**
* Inside my forked Medusa repository, I ran `yarn build` to compile the new TypeScript migration files.
* From the root of the **test project**, I then executed the migration command: `npx medusa migration run`.
4. **Verification:**
* The command successfully identified and ran only the new migration files I had created.
* I also confirmed via direct SQL queries that the old, redundant indexes were correctly dropped from all affected tables (`product_collection`, `customer_group`, etc.).
**What**
Currently, we are potentially providing an array of selector/data leading to fetching data sequentially before running on update which will fetch data again in batch and perform the update. Now we can pass the data directly which includes the id already and only perform one bulk fetch + one bulk update.
This pr also include a fix on the inventory validation, currently, only the item to update inventory is being checked, with this pr we also check the inventory for the items that needs to be created
**What**
Some steps were calling the modules even when nothing was needed which for some operations would create transaction for nothing leading to extra execution time that add up very quickly on cloud network

**What**
Currently, the `one-to-one` unique constraints does not account for deleted record. This prevents from inserting a new record wth the same fk if another one is deleted.
**Caveat**
`hasOne` with FK option is meant to be a special case, for example a many to one - one to many without defining the other side of the relation. In that case we don't handle this behaviour and keep it as it is

*What*
* Fixes#10490
* Expands any available customer_id into its customer_group_ids for cart
updates that add line items.
*Why*
* Cart updates from the storefront were overriding any valid price lists
that were correctly being shown in the storefront's product pages.
*How*
* Adds a new workflow step that expands an optional customer_id into the
customer_group_ids it belongs to.
* Uses this step in the addToCartWorkflow and
updateLineItemInCartWorkflow workflows.
*Testing*
* Using medusa-dev to test on a local backend.
* Adds integration tests for the addToCart and updateLineItemInCart
workflows.

**What**
Apply the `Module` util to each module to handle the export and provide the linkable configuration object.
- Most joiner config that does not have any special config are removed/cleaned up in favor of the autogenerated one or simpler one
- linkable are now available in all modules
- cleaned up the dependencies of the modules
FIXES CORE-2410
**What**
Update the `MedusaService` class, factory and types to remove the concept of main modules. The idea being that all method will be explicitly named and suffixes to represent the object you are trying to manipulate.
This pr also includes various fixes in different modules

**What**
- automatically build and consume connection and container loader if not exported by the module
- therefore load the services and repositories automatically, including baseRepository
- automatically build run and revert migrations if not provided
- cleaup modules to remove extra unnecessary bits and pieces
- remove the `initializeFactory` in favor of using `medusaApp`
Should drastically improve the module building DX by removing a lot of boilerplate to handle by the user, that plus the base entity should simplify quite a lot the flow cc @shahednasser
**Note**
I had to choose a way to identify connection and container loader from the exported loader from the module. I decided to go with named function `connectionLoader` and `containerLoader`, also, now the factories will return named function so if the user use the factories we are providing to build those loaders, the function will also be named and identified
