+## CreateIdentity Derivation Behavior
+
+When creating identities with `CreateIdentity()` (or `IdLE.Step.CreateIdentity`), the AD provider implements smart defaults to reduce boilerplate and improve workflow usability:
+
+### 1. SamAccountName Derivation
+
+**If `Attributes.SamAccountName` is missing or empty:**
+
+- When `IdentityKey` is **SamAccountName-like** (no `@`, not a GUID):
+  - **Derives** `SamAccountName = IdentityKey`
+  - Example: `IdentityKey='jdoe'` → `SamAccountName='jdoe'`
+  
+- When `IdentityKey` is a **UPN** (contains `@`):
+  - **Fails fast** with a clear error requiring explicit `SamAccountName`
+  - Rationale: Automatic truncation/sanitization introduces org-specific policy decisions and collision risks
+  
+- When `IdentityKey` is a **GUID**:
+  - **Fails fast** with a clear error requiring explicit `SamAccountName`
+  - Rationale: GUIDs are not valid SamAccountNames
+
+**Explicit values are never overridden:** If `Attributes.SamAccountName` is provided, it is always used as-is.
+
+### 2. UserPrincipalName Auto-Set
+
+**If `IdentityKey` is a UPN and `Attributes.UserPrincipalName` is missing or empty:**
+
+- **Auto-sets** `UserPrincipalName = IdentityKey`
+- Example: `IdentityKey='john.doe@contoso.com'` → `UserPrincipalName='john.doe@contoso.com'`
+
+**Explicit values are never overridden:** If `Attributes.UserPrincipalName` is provided, it is always used as-is.
+
+### 3. CN/RDN Name Derivation
+
+The AD object's Common Name (CN/RDN, used in the DistinguishedName) is derived using this priority order:
+
+1. **`Attributes.Name`** (explicit CN/RDN)
+2. **`Attributes.DisplayName`**
+3. **`GivenName + Surname`** (if both are present)
+4. **`IdentityKey`** (fallback)
+
+**Example:**
+```powershell
+# IdentityKey='jdoe', GivenName='John', Surname='Doe', DisplayName='John Doe'
+# → CN/RDN = 'John Doe' (from DisplayName)
+
+# IdentityKey='jdoe', GivenName='John', Surname='Doe'
+# → CN/RDN = 'John Doe' (from GivenName+Surname)
+
+# IdentityKey='jdoe'
+# → CN/RDN = 'jdoe' (fallback to IdentityKey)
+```
+
+**Verbose logging:** All derivations emit `Write-Verbose` messages for observability.
+
+### 4. Path Pass-Through
+
+**`Attributes.Path`** is always passed through to `New-ADUser -Path` when provided. No derivation or defaulting occurs at the provider level.
