### **Added**

#### Product Data Enhancements

**Average Buy Price (`avgBuyPrice`)**

The customer product representation now includes the new read-only field `avgBuyPrice`.

**Endpoints:**

* `GET /customers/{customerId}/products`
* `GET /products/{customerProductId}`

**Field:**

* `avgBuyPrice` (decimal, read-only, nullable)
* Represents the **average unit buy price** of the *currently held position*, expressed in the product currency.

**Calculation Logic:**

* Computed using **FIFO** based on executed buy transactions.
* For **fully closed (sold)** positions, the value is returned as **`0`**.

**Precision Rules:**

* Price < **1 EUR** → **8 decimal places**
* Price **1–100 EUR** → **4 decimal places**
* Price ≥ **100 EUR** → **2 decimal places**

***

#### **Tax Exemption Updates**

**Endpoint:** `PATCH /taxes/tax-exemption-orders`\
(Updates existing individual tax exemption orders)

**Supported changes:**

* `fsaAmount`
  * Must satisfy: `usedTaxExemption ≤ fsaAmount ≤ 1000`
* `fsaValidUntil`

**Cancellation rules:**

* `usedTaxExemption == 0` → cancellation allowed retroactively to **01.01** of the current year
* `usedTaxExemption > 0` → cancellation allowed only effective **31.12** of the current year

***

#### **User Management**

* Password Reset Support: Introduced functionality to reset a Partner User's password via `userId`. This resolves issues where users who deleted their welcome email or never logged in were unable to recover access.
* User Matching: Partner Users are now automatically matched to a Global ID upon creation (using First Name, Last Name, Birthday, and Birth Country) to ensure unique identification within the Partner Group.

***

### **Changed**

#### **Asset Type Configuration**

* Removed: `UNKNOWN` is no longer a valid `assetType` value
* Applies to Create/Update Asset Type Trading Profile endpoints
* Integrations must avoid sending this value

***

#### **Validation & Logic Improvements**

Delete Legal Representative:

* Added strict safeguards when calling the "Delete Legal Representative" endpoint:
  * Signatory Check: Deletion is rejected if the representative is an ACTIVE signatory proxy. (Status must be INACTIVE).
  * Remaining Rep Check: Deletion is rejected if no other Legal Representative exists for the entity (unless valid proxy logic applies).
  * Fictive UBO Check: Deletion is rejected if the representative is linked to active Fictive UBOs. These UBOs must be offboarded/deactivated first.
