 ### Migration Notes
 
 No action required for users. All existing code continues to work unchanged. This is an internal improvement that:

 - Removes a redundant generic method
 - Improves type safety and method dispatch clarity
 - Maintains all existing public APIs

 ### Module and Type Renaming
 
 #### Overview
+
 The InitialGuess module has been renamed to `Init` for better API ergonomics and more concise naming. This is a **breaking change** that requires users to update their imports and type references.
 
 #### What Changed
 
 ##### Module Name

 # Before (0.8.2-beta and earlier)

 ### InitialGuess Validation Architecture Change
 
 #### Overview
+
 Refactored the InitialGuess validation system to follow Single Responsibility Principle. This is an **internal architectural change** that does not affect the public API behavior but improves code organization.
 
 #### What Changed
 
 ##### Construction vs Validation Separation
+
 ```julia
 # Before (0.8.1-beta and earlier)
 # initial_guess() validated internally, build_initial_guess() had mixed responsibilities

 - Maintains all existing public APIs
 - Fixes a validation gap for direct `AbstractInitialGuess` inputs

 ### Module Migration to CTSolvers
 
 #### Overview
+
 Major refactoring where several modules have been moved from CTModels to the new CTSolvers package.
 
 #### Moved Modules
+
 The following modules are no longer part of CTModels and must be imported from CTSolvers:
 
 - **Options** → `using CTSolvers: Options`
-- **Strategies** → `using CTSolvers: Strategies` 
+- **Strategies** → `using CTSolvers: Strategies`
 - **Orchestration** → `using CTSolvers: Orchestration`
 - **Optimization** → `using CTSolvers: Optimization`
 - **Modelers** → `using CTSolvers: Modelers`
