Geant4's G4EXPATShim creates EXPAT::EXPAT (uppercase) with
IMPORTED_LOCATION set to ${EXPAT_LIBRARY}, which is empty when EXPAT
is found via conda's config-mode package (expat::expat, lowercase).

After find_package(Geant4), patch EXPAT::EXPAT with the real library
path taken from expat::expat IMPORTED_LOCATION_NOCONFIG, falling back
to find_library if needed.

+# Skill: Build uLib with Micromamba
+
+This skill provides instructions for building the uLib project using the micromamba environment.
+
+## Context
+- **Environment**: micromamba `uLib`
+- **Output Directory**: `build`
+- **CPU Usage**: All available cores
+
+## Instructions
+
+1. **Environment Setup**:
+   Ensure micromamba is properly initialized and the `uLib` environment is active.
+   ```bash
+   export MAMBA_EXE="/home/share/micromamba/bin/micromamba"
+   export MAMBA_ROOT_PREFIX="/home/share/micromamba"
+   eval "$(/home/share/micromamba/bin/micromamba shell hook --shell bash)"
+   micromamba activate uLib
+   ```
+
+2. **Full Rebuild (if needed)**:
+   If the `build` directory does not exist or a full reconfiguration is required:
+   ```bash
+   conan profile detect --force
+   conan install . --output-folder=build --build=missing
+   cmake --preset conan-release
+   ```
+
+3. **Incremental Build**:
+   Run the build command from the root directory, pointing to the `build` folder and using all cores.
+   ```bash
+   cmake --build build -j$(nproc)
+   ```
+
+4. **Specific Target Build**:
+   To build a specific target (e.g., gcompose):
+   ```bash
+   cmake --build build --target gcompose -j$(nproc)
+   ```

+Viewport click  →  Viewport::SelectProp3D()  →  QViewport::OnSelectionChanged()
-                →  emit puppetSelected(p)
+                →  emit prop3dSelected(p)
                 →  MainPanel: contextPanel->selectObject(p->GetContent())  [updates tree + PropertiesPanel]
                 →  MainPanel: firstPane->setObject(p)  [updates Display Properties panel]
 
 ContextPanel tree click  →  emit objectSelected(obj)
-                →  MainPanel: viewport->SelectPuppet(puppet)  [visual selection in VTK]

 ### Key Patterns
 - **Two signal systems coexist**: Qt signals (`Q_OBJECT`, `connect(...)`) for GUI; `uLib::Object::connect(...)` for domain signals.
-- **Display properties** flow: `Puppet::serialize_display()` → `display_properties_archive` → `RegisterDisplayProperty()` → `PropertyEditor(displayOnly=true)`. Must call `ULIB_ACTIVATE_DISPLAY_PROPERTIES` in the puppet constructor.
+- **Display properties** flow: `Prop3D::serialize_display()` → `display_properties_archive` → `RegisterDisplayProperty()` → `PropertyEditor(displayOnly=true)`. Must call `ULIB_ACTIVATE_DISPLAY_PROPERTIES` in the prop3d constructor.
-- **Puppet ↔ Object map**: `Viewport::m_ObjectToPuppet` allows lookup by domain object; `vtkObjectsContext::GetPuppet(obj)` does the same.
+- **Prop3D ↔ Object map**: `Viewport::m_ObjectToProp3D` allows lookup by domain object; `vtkObjectsContext::GetProp3D(obj)` does the same.

-# Aggoritm definition
-
-An algorithm in the uLib infrastructure is a class for containing a functional that can be dynamically loaded into memory as a plug-in.
-It derives from the base Object class and therefore can contain properties that define the serialization of operating parameters or the implementation of widgets for interactive parameter manipulation.
-The algorithm class is designed to be inserted into a Task, i.e., a class for managing the execution of scheduled operations. A task contains a Run and Stop method to start and stop execution. Furthermore, a task can be configured to work in cyclic or asynchronous mode: in cyclic mode it will be possible to define a cycle time, while in asynchronous mode a task can be hooked to a signal-slot of the Object structure or to a condition variable defined in the monitor pattern (Monitor.h).
-
-The algorithm in particular is defined as a template class on two types T_enc, T_dec. The encoder is a type for data input or another algorithm that is chained with this one that outputs data in the format compatible with input. The decoder is the type of data output or an algorithm compatible with it.

+# Serialization and Archives Internals
+
+This document explains the internal design of the `uLib` serialization system, which is built on top of **Boost.Serialization**. It provides custom archive implementations for various formats (XML, Text, Logging) and introduces **Human Readable Pairs (HRP)** for metadata-rich serialization.
+
+---
+
+## Architecture Overview
+
+The `uLib` archive system extends the standard `boost::archive` templates to add domain-specific features. The main components are:
+
+1.  **Custom Interface Layer**: Extends the default Boost archive API with additional operators and utilities.
+2.  **Specialized Archive Implementations**: Specialized classes for XML, Text, and Logging.
+3.  **HRP Support**: First-class support for `hrp` (Human Readable Pair) wrappers, which carry units, ranges, and descriptions.
+4.  **Static Registration System**: Macros and explicit instantiations to handle polymorphic types and compilation isolation.
+
+---
+
+## Custom Interface Layer
+
+All `uLib` archives use a custom interface defined in `Archives.h` via `uLib_interface_iarchive` and `uLib_interface_oarchive`. These templates add several key features:
+
+| Feature | Operator/Method | Description |
+|---|---|---|
+| **Mapping Operator** | `operator==` | Aliased to `operator&` (Boost's standard mapping operator). |
+| **Trace Operator** | `operator!=` | Used for trace/debug output of strings during serialization. |
+| **Type Registration** | `register_type<T>()` | Registers a class type with the archive's internal serializer map. |
+| **Standard IO** | `operator<<` / `operator>>` | Standard redirect for saving and loading. |
+
+These interfaces are applied to the archives using template specialization of `boost::archive::detail::interface_iarchive` and `interface_oarchive`.
+
+---
+
+## Archive Variants
+
+### XML Archives (`xml_iarchive`, `xml_oarchive`)
+These inherit from `boost::archive::xml_iarchive_impl` and `xml_oarchive_impl`. 
+- **Internals**: They override `load_override` and `save_override` to handle `boost::serialization::hrp<T>` specifically. 
+- **XML Mapping**: When saving an `hrp`, it uses `save_start(name)` and `save_end(name)` to wrap the value in a named XML tag.
+
+### Text Archives (`text_iarchive`, `text_oarchive`)
+Standard text-based archives used for compact serialization. They use `StringReader` to consume decorative text markers during loading.
+
+### Human Readable Text (`hrt_iarchive`, `hrt_oarchive`)
+These are "naked" text archives that suppress most of Boost's internal metadata (object IDs, class IDs, versions).
+- **Goal**: Produce text output that is easy for humans to read and edit.
+- **Internals**: All overrides for Boost internal types (like `object_id_type`, `version_type`, etc.) are implemented as no-ops.
+
+### Log Archive (`log_archive`)
+An XML-based output archive specifically for debug logging.
+- **Internals**: It forces every object into a Name-Value Pair (NVP) even if not provided by the user, and strips all technical metadata to keep the logs clean.
+
+---
+
+## HRP (Human Readable Pair) Integration
+
+`hrp` is a core `uLib` wrapper (defined in `Serializable.h`) that extends Boost's `nvp`:
+
+```cpp
+// Example of HRP usage
+ar & HRP2("Energy", m_energy, "MeV").range(0, 100);
+```
+
+### Internal Handling in Archives
+Archives in `Archives.h` provide specific `save_override`/`load_override` for `hrp<T>`:
+- **XML**: Maps the `name()` to an XML tag.
+- **HRT**: Formats as `name: value [units]\n`.
+- **Log**: Converts it to a standard Boost `nvp` for consistent XML logging.
+
+---
+
+## Registration and Polymorphism
+
+### Registration Macro
+The `ULIB_SERIALIZATION_REGISTER_ARCHIVE(Archive)` macro is crucial for polymorphic serialization. It instantiates the necessary template machinery to link the custom `Archive` type with any `Serializable` class exported via `BOOST_CLASS_EXPORT`.
+
+### Explicit Instantiation
+To reduce compilation times and provide a single point of failure for link-time issues, `uLib` uses explicit instantiations in `src/Core/Archives.cpp`. This file includes the `.ipp` implementation files from Boost and instantiates the `archive_serializer_map` and implementation classes for all `uLib` archive types.
+
+---
+
+## Utility: StringReader
+The `StringReader` utility is used internally by text-based archives to parse and skip literals. For example:
+- When loading a string literal from a text archive, `StringReader` consumes whitespace and ensures the stream matches the expected string, failing if there is a mismatch.
+- This is vital for maintaining the structure of human-readable formats.

+# Prop3D
+
+`uLib::Vtk::Prop3D` is a bridge class that wraps VTK 3D representations (`vtkProp`, `vtkProp3D`) and integrates them into the `uLib` object model. It allows the framework to manage visual objects, synchronize them with underlying data models, and expose display-specific properties to the GUI.
+
+## Inheritance
+`uLib::Vtk::Prop3D` : `uLib::Object`
+
+## Key Functionalities
+
+### VTK Integration
+The class provides access to the underlying VTK objects:
+- `GetProp()`: Returns the `vtkProp`.
+- `GetProxyProp()`: Returns the `vtkProp3D`.
+- `GetParts()` / `GetProps()`: Returns `vtkPropCollection` for composite objects.
+
+### Model-View Synchronization
+`Prop3D` ensures that the visual representation stays in sync with the domain model:
+- `Update()`: Synchronizes the VTK representation based on current internal state and properties. Should be called when model data changes.
+- `SyncFromVtk()`: Updates internal state using data from the VTK representation (e.g., after user interaction via gizmos in the 3D view).
+- `GetContent()`: Returns the `uLib::Object` that this `Prop3D` represents visually.
+
+### Visual Appearance
+- **Color & Opacity**: `SetColor(r, g, b)` and `SetOpacity(alpha)`.
+- **Selection**: `SetSelectable(bool)` and `SetSelected(bool)` to manage interactivity and highlighting.
+- **BBox/Scale**: `ShowBoundingBox(bool)` and `ShowScaleMeasures(bool)`.
+
+### Rendering Modes
+The rendering style can be controlled via the `Representation` enum:
+- `Points`
+- `Wireframe`
+- `Surface`
+- `SurfaceWithEdges`
+- `Volume`
+- `Outline`
+- `Slice`
+
+### Display Properties System
+`Prop3D` implements a system to expose specific properties (often marked as `hrp` - human readable properties) to a property editor in the GUI.
+
+- `GetDisplayProperties()`: Returns the list of properties registered for display.
+- `RegisterDisplayProperty(uLib::PropertyBase*)`: Adds a property to the display list.
+- `serialize_display(...)`: A virtual method that subclasses implement to define which properties should be exposed.
+
+#### Activating Display Properties
+To automatically populate the display properties list, the `ULIB_ACTIVATE_DISPLAY_PROPERTIES` macro should be called in the constructor. This triggers `serialize_display` using a `display_properties_archive`.
+
+## Implementation Details
+`Prop3D` uses the Pimpl idiom (via `Prop3DData *pd`) to hide VTK-specific implementation details and reduce header dependencies.

+# Geant integration
+
+Geant4 integration in uLib is done through the `HEP/Geant` module.
+The module represets a set of wrapper for geant objects that are also deriving from uLib::Object so they can be used in the uLib::Object tree and visualized with the uLib::Vtk module and driven py properties.
+
+# Geant Solid integration
+
+Geant solid in uLib is represented by the `uLib::Geant::Solid` class and mainly BoxSolid and TessellatedSolid. The solids in Geant does not have the possibility to set properties on the fly so we need to create a new solid every time we want to change the properties of a solid. This is done by creating a new `uLib::Geant::Solid` object and setting the properties of the new solid. The new solid is then added to the `uLib::Geant::Solid` object as a child. The old solid is then removed from the `uLib::Geant::Solid` object as a child. The old solid is then deleted. However id some of the properties can be set then the library will drive the change in the solid update.
+
+The idea is to have a mapping of solid properties that can be used in uLib for Qt representation or vtk representation. then when the property is changed the signaling will update the property in uLib and then the solid will be updated. If the Geant property can be applied to the G4 object underneath then the update will apply the change, in case it is not possible to apply the change to the G4 object underneath then the G4 element will be recreated. 
+In any case a updated singal is emitted and the related element that use that solid is updated ( for instance the scene ).

+# Properties and the vtk-gui representation
+
+This is the rationale behind the connection between TRS properties and Prop3D Transformation.
+
+The properties from model get propoagated via Object signalling system (the Update signal) to the vtkRepresentation and to the Qt widgets so that the overall transformation of the model reflects into a modification of its representation in vtk and in the gui. 
+
+In addition the properties need to be adjusted also from vtk, for example if user uses handlerwidget to change the transformation this is eventually applied to Prop3D and Prop3D should propagate the transformation change to the vtk representation object (for instance vtkContainerBox) and the latter eventually propagates the change into the model.
+
+the Prop3D or the vtk representation wrapper ( vtkContainerBox for instance is the wrapper od ContainerBox ) should not directly show the transformation of the handlerwidget but it should show the transformation of the model once applied so we are always seeing the actual aspect of the model reflected to the vtk representation and not the other way around.
+
+So in syntesis the model is the master and the vtk representation and the gui are the slaves of any modification, but the vtkHandlerWidget is able to apply a transform that should be applied to the model and then the model should propagate the transformation change to the vtk representation and to the gui.
+
+## The Prop3D
+
+The prop3d is the proxy of the spatial placement of objects in the scene. Prop3Ds should have an internal ContainerBox that is shown in the scene around the content to be able to pick Prop3D from vtkViewport using the handler widget. The HandlerWidget moves the Prop3D ContainerBox (the red Highlight element whe selected) to reflect the handler current transformation, but the transformation is propagated to the derived Prop3D classes like vtkContainerBox. 
+
+The vtkHandlerWidget should handle the transformation of the prop3d internal ContainerBox. The changes of the ContainerBox will be propagated to the derived classes and eventually to the model. 
+
+
+
+
+
+
+## ACTIVATE PROPERTIES
+
+ULIB_ACTIVATE_PROPERTIES must run after all member initialization, with the vtable pointing to the most-derived type. This is why it has to be in each constructor — in C++, virtual dispatch only works correctly after a class's vtable is installed, which happens at the start of each level's constructor body.
+
+### Option 1 — End-of-class macro (no constructor boilerplate)
+Declare a private member activator as the last member of the class. Its constructor runs after all other members, and at that point the vtable is already Derived's:
+
+
+// In Property.h, add alongside ULIB_ACTIVATE_PROPERTIES:
+#define ULIB_DECLARE_PROPERTIES(SelfType) \
+private: \
+    struct _PropActivator { \
+        _PropActivator(SelfType* self) { \
+            uLib::Archive::property_register_archive ar(self); \
+            ar & *self; \
+        } \
+    } _prop_activator{this};
+Usage in ContainerBox.h — place it just before the closing brace:
+
+
+class ContainerBox : public TRS {
+public:
+    // ... all constructors, no more ULIB_ACTIVATE_PROPERTIES(*this)
+
+    ULIB_DECLARE_PROPERTIES(ContainerBox)  // ← replaces all 3 constructor calls
+};
+Tradeoff: Works perfectly for single-level classes. For hierarchies where multiple levels use the macro, RegisterDynamicProperty must deduplicate by name (skip if already registered). Requires one line per class in the class body, but zero lines in constructors.
+
+### Option 2 — Lazy init via virtual InitProperties() in Object
+Modify Object to call a virtual hook on first GetProperties():
+
+
+// In Object.h:
+class Object {
+protected:
+    virtual void InitProperties() {}   // override in derived
+public:
+    const std::vector<PropertyBase*>& GetProperties() const {
+        if (!m_propertiesInitialized) {
+            const_cast<Object*>(this)->m_propertiesInitialized = true;
+            const_cast<Object*>(this)->InitProperties();
+        }
+        return m_properties;
+    }
+};
+Then a CRTP base handles the rest without any macro:
+
+
+template<typename Derived>
+class PropertyObject : public Object {
+protected:
+    void InitProperties() override {
+        uLib::Archive::property_register_archive ar(this);
+        ar & *static_cast<Derived*>(this);
+    }
+};
+Usage — just change the base class:
+
+
+class ContainerBox : public PropertyObject<ContainerBox>, public TRS { ... };
+// Nothing else needed — properties activated on first GetProperties() call
+Tradeoff: Most "automatic" — pure inheritance, no constructor or class-body macros. But requires modifying Object (adding m_propertiesInitialized flag + virtual hook), and lazy init means properties aren't available until first access. Also doesn't work well with multiple inheritance (which TRS likely involves).
+
+Option 3 — CRTP doesn't work from the base constructor
+Just to be explicit: a CRTP base that calls ULIB_ACTIVATE_PROPERTIES in its own constructor won't work, because when PropertyObject<Derived>'s constructor runs, the vtable is PropertyObject<Derived>'s — Derived::serialize() hasn't been installed yet. So ar & *self calls Object::serialize() (a no-op).
+
+Recommendation
+Option 1 is the least invasive and safest. Add deduplication to RegisterDynamicProperty in Object.cpp to guard against re-registration when hierarchies stack activators, then replace every ULIB_ACTIVATE_PROPERTIES(*this) in constructors with a single ULIB_DECLARE_PROPERTIES(ClassName) at the end of the class body.
+
+Option 2 is cleaner to use but requires changing the Object interface and has the lazy-init semantic change — only worth it if you want zero-touch activation across the entire framework.

+/**
+ * @file Debug.h
+ * @brief Unified Debugging and Monitoring System for uLib.
+ *
+ * # Debug System Documentation
+ *
+ * The `Debug` system provides a flexible, adapter-based mechanism for monitoring
+ * and outputting internal variables and states without hardcoding output logic
+ * into core classes. 
+ *
+ * ## Architecture
+ * 
+ * The system follows an adapter pattern:
+ * 
+ * - **`DebugAdapterInterface`**: The base interface for all output targets. 
+ *   Subclasses define how primitive types and strings are handled (e.g., printing 
+ *   to `std::cout`, writing to a log file, or updating a real-time UI widget).
+ *
+ * - **`Debug` Class**: The central registry. It stores:
+ *   1.  A list of "Adapters" (`DebugAdapterInterface`).
+ *   2.  A list of "Items" to monitor. Each item is a reference to a variable 
+ *       associated with a name.
+ *
+ * - **Type Safety**: Although variables are stored using `boost::any` (type erasure), 
+ *   the system automatically preserves the original type information via 
+ *   internal template adapters (`AnyCastAdapter`), ensuring that the correct 
+ *   overload of the adapter interface is called.
+ *
+ * ## Core Components
+ * 
+ * | Component | Description |
+ * | :--- | :--- |
+ * | `Debug` | The main controller used to add adapters and register variables. |
+ * | `DebugAdapterInterface` | Virtual base for creating new output methods. |
+ * | `DebugAdapterText` | A simple built-in adapter for `std::ostream` output. |
+ *
+ * ## How to Use
+ *
+ * ### 1. Initialize the Debug Object
+ * ```cpp
+ * uLib::Debug dbg;
+ * ```
+ *
+ * ### 2. Add an Adapter
+ * ```cpp
+ * uLib::DebugAdapterText console(std::cout);
+ * dbg.AddAdapter(console);
+ * ```
+ *
+ * ### 3. Register Variables to Monitor
+ * Use the `operator()` to bind a variable by reference.
+ * ```cpp
+ * int frameCount = 0;
+ * std::string state = "Initializing";
+ * dbg("Frames", frameCount);
+ * dbg("Status", state);
+ * ```
+ *
+ * ### 4. Update
+ * Call `Update()` periodically (e.g., once per frame) to push the current 
+ * values of all registered variables to all connected adapters.
+ * ```cpp
+ * while(running) {
+ *    frameCount++;
+ *    dbg.Update(); // This triggers the output
+ * }
+ * ```
+ */
