+# Plan for Autotest GUI Mode Implementation
+
+**I. Objective:**
+Create an `autotest.py` script that can launch the Asset Processor GUI headlessly, load a predefined asset (`.zip`), select a predefined preset, verify the predicted rule structure against an expected JSON, trigger processing to a predefined output directory, check the output, and analyze logs for errors or specific messages. This serves as a sanity check for core GUI-driven workflows.
+
+**II. `TestFiles` Directory:**
+A new directory named `TestFiles` will be created in the project root (`c:/Users/Theis/Assetprocessor/Asset-Frameworker/TestFiles/`). This directory will house:
+*   Sample asset `.zip` files for testing (e.g., `TestFiles/SampleAsset1.zip`).
+*   Expected rule structure JSON files (e.g., `TestFiles/SampleAsset1_PresetX_expected_rules.json`).
+*   A subdirectory for test outputs (e.g., `TestFiles/TestOutputs/`).
+
+**III. `autotest.py` Script:**
+
+1.  **Location:** `c:/Users/Theis/Assetprocessor/Asset-Frameworker/autotest.py` (or `scripts/autotest.py`).
+2.  **Command-Line Arguments (with defaults pointing to `TestFiles/`):**
+    *   `--zipfile`: Path to the test asset. Default: `TestFiles/default_test_asset.zip`.
+    *   `--preset`: Name of the preset. Default: `DefaultTestPreset`.
+    *   `--expectedrules`: Path to expected rules JSON. Default: `TestFiles/default_test_asset_rules.json`.
+    *   `--outputdir`: Path for processing output. Default: `TestFiles/TestOutputs/DefaultTestOutput`.
+    *   `--search` (optional): Log search term. Default: `None`.
+    *   `--additional-lines` (optional): Context lines for log search. Default: `0`.
+3.  **Core Structure:**
+    *   Imports necessary modules from the main application and PySide6.
+    *   Adds project root to `sys.path` for imports.
+    *   `AutoTester` class:
+        *   **`__init__(self, app_instance: App)`:**
+            *   Stores `app_instance` and `main_window`.
+            *   Initializes `QEventLoop`.
+            *   Connects `app_instance.all_tasks_finished` to `self._on_all_tasks_finished`.
+            *   Loads expected rules from the `--expectedrules` file.
+        *   **`run_test(self)`:** Orchestrates the test steps sequentially:
+            1.  Load ZIP (`main_window.add_input_paths()`).
+            2.  Select Preset (`main_window.preset_editor_widget.editor_preset_list.setCurrentItem()`).
+            3.  Await Prediction (using `QTimer` to poll `main_window._pending_predictions`, manage with `QEventLoop`).
+            4.  Retrieve & Compare Rulelist:
+                *   Get actual rules: `main_window.unified_model.get_all_source_rules()`.
+                *   Convert actual rules to comparable dict (`_convert_rules_to_comparable()`).
+                *   Compare with loaded expected rules (`_compare_rules()`). If mismatch, log and fail.
+            5.  Start Processing (emit `main_window.start_backend_processing` with rules and output settings).
+            6.  Await Processing (use `QEventLoop` waiting for `_on_all_tasks_finished`).
+            7.  Check Output Path (verify existence of output dir, list contents, basic sanity checks like non-emptiness or presence of key asset folders).
+            8.  Retrieve & Analyze Logs (`main_window.log_console.log_console_output.toPlainText()`, filter by `--search`, check for tracebacks).
+            9.  Report result and call `cleanup_and_exit()`.
+        *   **`_check_prediction_status(self)`:** Slot for prediction polling timer.
+        *   **`_on_all_tasks_finished(self, processed_count, skipped_count, failed_count)`:** Slot for `App.all_tasks_finished` signal.
+        *   **`_convert_rules_to_comparable(self, source_rules_list: List[SourceRule]) -> dict`:** Converts `SourceRule` objects to the JSON structure defined below.
+        *   **`_compare_rules(self, actual_rules_data: dict, expected_rules_data: dict) -> bool`:** Implements Option 1 comparison logic:
+            *   Errors if an expected field is missing or its value mismatches.
+            *   Logs (but doesn't error on) fields present in actual but not in expected.
+        *   **`_process_and_display_logs(self, logs_text: str)`:** Handles log filtering/display.
+        *   **`cleanup_and_exit(self, success=True)`:** Quits `QCoreApplication` and `sys.exit()`.
+    *   `main()` function:
+        *   Parses CLI arguments.
+        *   Initializes `QApplication`.
+        *   Instantiates `main.App()` (does *not* show the GUI).
+        *   Instantiates `AutoTester(app_instance)`.
+        *   Uses `QTimer.singleShot(0, tester.run_test)` to start the test.
+        *   Runs `q_app.exec()`.

+# User Guide: Usage - Automated GUI Testing (`autotest.py`)
+
+This document explains how to use the `autotest.py` script for automated sanity checks of the Asset Processor Tool's GUI-driven workflow.
+
+## Overview
+
+The `autotest.py` script provides a way to run predefined test scenarios headlessly (without displaying the GUI). It simulates the core user actions: loading an asset, selecting a preset, allowing rules to be predicted, processing the asset, and then checks the results against expectations. This is primarily intended as a developer tool for regression testing and ensuring core functionality remains stable.
+
+## Running the Autotest Script
+
+From the project root directory, you can run the script using Python:
+
+```bash
+python autotest.py [OPTIONS]
+```
+
+### Command-Line Options
+
+The script accepts several command-line arguments to configure the test run. If not provided, they use predefined default values.
+
+*   `--zipfile PATH_TO_ZIP`:
+    *   Specifies the path to the input asset `.zip` file to be used for the test.
+    *   Default: `TestFiles/BoucleChunky001.zip`
+*   `--preset PRESET_NAME`:
+    *   Specifies the name of the preset to be selected and used for rule prediction and processing.
+    *   Default: `Dinesen`
+*   `--expectedrules PATH_TO_JSON`:
+    *   Specifies the path to a JSON file containing the expected rule structure that should be generated after the preset is applied to the input asset.
+    *   Default: `TestFiles/test-BoucleChunky001.json`
+*   `--outputdir PATH_TO_DIR`:
+    *   Specifies the directory where the processed assets will be written.
+    *   Default: `TestFiles/TestOutputs/DefaultTestOutput`
+*   `--search "SEARCH_TERM"` (optional):
+    *   A string to search for within the application logs generated during the test run. If found, matching log lines (with context) will be highlighted.
+    *   Default: None
+*   `--additional-lines NUM_LINES` (optional):
+    *   When using `--search`, this specifies how many lines of context before and after each matching log line should be displayed. A good non-zero value is 1-2.
+    *   Default: `0`
+
+**Example Usage:**
+
+```bash
+# Run with default test files and settings
+python autotest.py
+
+# Run with specific test files and search for a log message
+python autotest.py --zipfile TestFiles/MySpecificAsset.zip --preset MyPreset --expectedrules TestFiles/MySpecificAsset_rules.json --outputdir TestFiles/TestOutputs/MySpecificOutput --search "Processing complete for asset"
+```
+
+## `TestFiles` Directory
+
+The autotest script relies on a directory named `TestFiles` located in the project root. This directory should contain:
+
+*   **Test Asset `.zip` files:** The actual asset archives used as input for tests (e.g., `default_test_asset.zip`, `MySpecificAsset.zip`).
+*   **Expected Rules `.json` files:** JSON files defining the expected rule structure for a given asset and preset combination (e.g., `default_test_asset_rules.json`, `MySpecificAsset_rules.json`). The structure of this file is detailed in the main autotest plan (`AUTOTEST_GUI_PLAN.md`).
+*   **`TestOutputs/` subdirectory:** This is the default parent directory where the autotest script will create specific output folders for each test run (e.g., `TestFiles/TestOutputs/DefaultTestOutput/`).
+
+## Test Workflow
+
+When executed, `autotest.py` performs the following steps:
+
+1.  **Initialization:** Parses command-line arguments and initializes the main application components headlessly.
+2.  **Load Expected Rules:** Loads the `expected_rules.json` file.
+3.  **Load Asset:** Loads the specified `.zip` file into the application.
+4.  **Select Preset:** Selects the specified preset. This triggers the internal rule prediction process.
+5.  **Await Prediction:** Waits for the rule prediction to complete.
+6.  **Compare Rules:** Retrieves the predicted rules from the application and compares them against the loaded expected rules. If there's a mismatch, the test typically fails at this point.
+7.  **Start Processing:** If the rules match, it initiates the asset processing pipeline, directing output to the specified output directory.
+8.  **Await Processing:** Waits for all backend processing tasks to complete.
+9.  **Check Output:** Verifies the existence of the output directory and lists its contents. Basic checks ensure some output was generated.
+10. **Analyze Logs:** Retrieves logs from the application. If a search term was provided, it filters and displays relevant log portions. It also checks for Python tracebacks, which usually indicate a failure.
+11. **Report Result:** Prints a summary of the test outcome (success or failure) and exits with an appropriate status code (0 for success, 1 for failure).
+
+## Interpreting Results
+
+*   **Console Output:** The script will log its progress and the results of each step to the console.
+*   **Log Analysis:** Pay attention to the log output, especially if a `--search` term was used or if any tracebacks are reported.
+*   **Exit Code:**
+    *   `0`: Test completed successfully.
+    *   `1`: Test failed at some point (e.g., rule mismatch, processing error, traceback found).
+*   **Output Directory:** Inspect the contents of the specified output directory to manually verify the processed assets if needed.
+
+This automated test helps ensure the stability of the core processing logic when driven by GUI-equivalent actions.
+
+Note: Under some conditions, the autotest will exit with errorcode "3221226505". This has no consequence and can therefor be ignore.

 This document provides technical details about the configuration system and the structure of preset files for developers working on the Asset Processor Tool.
 
-## Configuration Flow
+## Configuration System Overview
 
-The tool utilizes a two-tiered configuration system managed by the `configuration.py` module:
+The tool's configuration is managed by the `configuration.py` module and loaded from several JSON files, providing a layered approach for defaults, user overrides, definitions, and source-specific presets.
 
-1.  **Application Settings (`config/app_settings.json`):** This JSON file defines the core global default settings, constants, and rules that apply generally across different asset sources (e.g., the global `OUTPUT_DIRECTORY_PATTERN` and `OUTPUT_FILENAME_PATTERN`, standard image resolutions, map merge rules, output format rules, Blender paths, `FILE_TYPE_DEFINITIONS`, `ASSET_TYPE_DEFINITIONS`). See the [User Guide: Output Structure](../01_User_Guide/09_Output_Structure.md#available-tokens) for a list of available tokens for these patterns.
+### Configuration Files
-*   **`FILE_TYPE_DEFINITIONS` Enhancements:**
-        *   **`keybind` Property:** Each file type object within `FILE_TYPE_DEFINITIONS` can now optionally include a `keybind` property. This property accepts a single character string (e.g., `"C"`, `"R"`) representing the keyboard key. In the GUI, this key (typically combined with `Ctrl`, or standalone like `F2` for asset naming) is used as a shortcut to set or toggle the corresponding file type for selected items in the Preview Table.
-            *Example:*
-            ```json
-            "MAP_COL": {
-                "description": "Color/Albedo Map",
-                "color": [200, 200, 200],
-                "examples": ["albedo", "col", "basecolor"],
-                "standard_type": "COL",
-                "bit_depth_rule": "respect",
-                "is_grayscale": false,
-                "keybind": "C"
-            },
-            ```
-        *   **New File Type `MAP_GLOSS`:** A new standard file type, `MAP_GLOSS`, has been added. It is typically configured as follows:
-            *Example:*
-            ```json
-            "MAP_GLOSS": {
-                "description": "Glossiness Map",
-                "color": [180, 180, 220],
-                "examples": ["gloss", "gls"],
-                "standard_type": "GLOSS",
-                "bit_depth_rule": "respect",
-                "is_grayscale": true,
-                "keybind": "R"
-            }
-            ```
-            Note: The `keybind` "R" for `MAP_GLOSS` is often shared with `MAP_ROUGH` to allow toggling between them.
-2.  **LLM Settings (`config/llm_settings.json`):** This JSON file contains settings specifically related to the LLM predictor, such as the API endpoint, model name, prompt template, and examples. These settings can be edited through the GUI using the `LLMEditorWidget`.
-3.  **Preset Files (`Presets/*.json`):** These JSON files define supplier-specific rules and overrides. They contain patterns to interpret filenames, classify map types, handle variants, define naming conventions, and specify other source-specific behaviors.
 
-The `configuration.py` module contains the `Configuration` class (for loading/merging settings for processing) and standalone functions like `load_base_config()` (for accessing `app_settings.json` directly) and `save_llm_config()` / `save_base_config()` (for writing settings back to files). Note that the old `config.py` file has been deleted.
+The tool's configuration is loaded from several JSON files, providing a layered approach for defaults, user overrides, definitions, and source-specific presets.
+
+1.  **Application Settings (`config/app_settings.json`):** This JSON file defines the core global default settings, constants, and rules that apply generally across different asset sources (e.g., the global `OUTPUT_DIRECTORY_PATTERN` and `OUTPUT_FILENAME_PATTERN`, standard image resolutions, map merge rules, output format rules, Blender paths, temporary directory prefix, initial scaling mode, merge dimension mismatch strategy). See the [User Guide: Output Structure](../01_User_Guide/09_Output_Structure.md#available-tokens) for a list of available tokens for these patterns.
+    *   *Note:* `ASSET_TYPE_DEFINITIONS` and `FILE_TYPE_DEFINITIONS` are no longer stored here; they have been moved to dedicated files.
+    *   It also includes settings for new features like the "Low-Resolution Fallback":
+        *   `ENABLE_LOW_RESOLUTION_FALLBACK` (boolean): Enables or disables the generation of "LOWRES" variants for small source images. Defaults to `true`.
+        *   `LOW_RESOLUTION_THRESHOLD` (integer): The pixel dimension threshold (largest side) below which a "LOWRES" variant is created if the feature is enabled. Defaults to `512`.
+
+2.  **User Settings (`config/user_settings.json`):** This optional JSON file allows users to override specific settings defined in `config/app_settings.json`. If this file exists, its values for corresponding keys will take precedence over the base application settings. This file is primarily managed through the GUI's Application Preferences Editor.
+
+3.  **Asset Type Definitions (`config/asset_type_definitions.json`):** This dedicated JSON file contains the definitions for different asset types (e.g., Surface, Model, Decal), including their descriptions, colors for UI representation, and example usage strings.
+
+4.  **File Type Definitions (`config/file_type_definitions.json`):** This dedicated JSON file contains the definitions for different file types (specifically texture maps and models), including descriptions, colors for UI representation, examples of keywords/patterns, a standard alias (`standard_type`), bit depth handling rules (`bit_depth_rule`), a grayscale flag (`is_grayscale`), and an optional GUI keybind (`keybind`).
+    *   **`keybind` Property:** Each file type object within `FILE_TYPE_DEFINITIONS` can optionally include a `keybind` property. This property accepts a single character string (e.g., `"C"`, `"R"`) representing the keyboard key. In the GUI, this key (typically combined with `Ctrl`) is used as a shortcut to set or toggle the corresponding file type for selected items in the Preview Table.
+        *Example:*
+        ```json
+        "MAP_COL": {
+            "description": "Color/Albedo Map",
+            "color": "#ffaa00",
+            "examples": ["_col.", "_basecolor.", "albedo", "diffuse"],
+            "standard_type": "COL",
+            "bit_depth_rule": "force_8bit",
+            "is_grayscale": false,
+            "keybind": "C"
+        },
+        ```
+        Note: The `bit_depth_rule` property in `FILE_TYPE_DEFINITIONS` is the primary source for determining bit depth handling for a given map type.
+
+5.  **Supplier Settings (`config/suppliers.json`):** This JSON file stores settings specific to different asset suppliers. It is now structured as a dictionary where keys are supplier names and values are objects containing supplier-specific configurations.
+    *   **Structure:**
+        ```json
+        {
+          "SupplierName1": {
+            "setting_key1": "value",
+            "setting_key2": "value"
+          },
+          "SupplierName2": {
+            "setting_key1": "value"
+          }
+        }
+        ```
+    *   **`normal_map_type` Property:** A key setting within each supplier's object is `normal_map_type`, specifying whether normal maps from this supplier use "OpenGL" or "DirectX" conventions.
+        *Example:*
+        ```json
+        {
+          "Poliigon": {
+            "normal_map_type": "DirectX"
+          },
+          "Dimensiva": {
+            "normal_map_type": "OpenGL"
+          }
+        }
+        ```
+
+6.  **LLM Settings (`config/llm_settings.json`):** This JSON file contains settings specifically related to the LLM predictor, such as the API endpoint, model name, prompt template, and examples. These settings are managed through the GUI using the `LLMEditorWidget`.
+
+7.  **Preset Files (`Presets/*.json`):** These JSON files define source-specific rules and overrides. They contain patterns to interpret filenames, classify map types, handle variants, define naming conventions, and specify other source-specific behaviors. Preset settings override values from `app_settings.json` and `user_settings.json` where applicable.
+
+
+### Configuration Loading and Access
+
+The `configuration.py` module contains the `Configuration` class and standalone functions for loading and saving settings.
+
+*   **`Configuration` Class:** This is the primary class used by the processing engine and other core components. When initialized with a `preset_name`, it loads settings in the following order, with later files overriding earlier ones for shared keys:
+    1.  `config/app_settings.json` (Base Defaults)
+    2.  `config/user_settings.json` (User Overrides - if exists)
+    3.  `config/asset_type_definitions.json` (Asset Type Definitions)
+    4.  `config/file_type_definitions.json` (File Type Definitions)
+    5.  `config/llm_settings.json` (LLM Settings)
+    6.  `Presets/{preset_name}.json` (Preset Overrides)
+
+    The loaded settings are merged into internal dictionaries, and most are accessible via instance properties (e.g., `config.output_base_dir`, `config.llm_endpoint_url`, `config.get_asset_type_definitions()`). Regex patterns defined in the merged configuration are pre-compiled for performance.
+
+*   **`load_base_config()` function:** This standalone function is primarily used by the GUI for initial setup and displaying default/user-overridden settings before a specific preset is selected. It loads and merges the following files:
+    1.  `config/app_settings.json`
+    2.  `config/user_settings.json` (if exists)
+    3.  `config/asset_type_definitions.json`
+    4.  `config/file_type_definitions.json`
+
+    It returns a single dictionary containing the combined settings and definitions.
+
+*   **Saving Functions:**
+    *   `save_base_config(settings_dict)`: Saves the provided dictionary to `config/app_settings.json`. (Used less frequently now for user-driven saves).
+    *   `save_user_config(settings_dict)`: Saves the provided dictionary to `config/user_settings.json`. Used by `ConfigEditorDialog`.
+    *   `save_llm_config(settings_dict)`: Saves the provided dictionary to `config/llm_settings.json`. Used by `LLMEditorWidget`.
+
+## Supplier Management (`config/suppliers.json`)
+
+A file, `config/suppliers.json`, is used to store a persistent list of known supplier names. This file is a simple JSON array of strings.
+
+*   **Purpose:** Provides a list of suggestions for the "Supplier" field in the GUI's Unified View, enabling auto-completion.
+*   **Management:** The GUI's `SupplierSearchDelegate` is responsible for loading this list on startup, adding new, unique supplier names entered by the user, and saving the updated list back to the file.
+
+## GUI Configuration Editors
+
+The GUI provides dedicated editors for modifying configuration files:
+
+*   **`ConfigEditorDialog` (`gui/config_editor_dialog.py`):** Edits user-configurable application settings.
+*   **`LLMEditorWidget` (`gui/llm_editor_widget.py`):** Edits the LLM-specific settings.
+
+### `ConfigEditorDialog` (`gui/config_editor_dialog.py`)
+
+The GUI includes a dedicated editor for modifying user-configurable settings. This is implemented in `gui/config_editor_dialog.py`.
+
+*   **Purpose:** Provides a user-friendly interface for viewing the effective application settings (defaults + user overrides + definitions) and editing the user-specific overrides.
+*   **Implementation:** The dialog loads the effective settings using `load_base_config()`. It presents relevant settings in a tabbed layout ("General", "Output & Naming", etc.). When saving, it now performs a **granular save**: it loads the current content of `config/user_settings.json`, identifies only the settings that were changed by the user during the current dialog session (by comparing against the initial state), updates only those specific values in the loaded `user_settings.json` content, and saves the modified content back to `config/user_settings.json` using `save_user_config()`. This preserves any other settings in `user_settings.json` that were not touched. The dialog displays definitions from `asset_type_definitions.json` and `file_type_definitions.json` but does not save changes to these files.
+*   **Limitations:** Currently, editing complex fields like `IMAGE_RESOLUTIONS` or the full details of `MAP_MERGE_RULES` via the UI is not fully supported for saving to `user_settings.json`.
+
+### `LLMEditorWidget` (`gui/llm_editor_widget.py`)
+
+*   **Purpose:** Provides a user-friendly interface for viewing and editing the LLM settings defined in `config/llm_settings.json`.
+*   **Implementation:** Uses tabs for "Prompt Settings" and "API Settings". Allows editing the prompt, managing examples, and configuring API details. When saving, it also performs a **granular save**: it loads the current content of `config/llm_settings.json`, identifies only the settings changed by the user in the current session, updates only those values, and saves the modified content back to `config/llm_settings.json` using `configuration.save_llm_config()`.
+
+## Preset File Structure (`Presets/*.json`)
+
+Preset files are the primary way to adapt the tool to new asset sources. Developers should use `Presets/_template.json` as a starting point. Key fields include:
+
+*   `supplier_name`: The name of the asset source (e.g., `"Poliigon"`). Used for output directory naming.
+*   `map_type_mapping`: A list of dictionaries, each mapping source filename patterns/keywords to a specific file type. The `target_type` for this mapping **must** be a key from the `FILE_TYPE_DEFINITIONS` now located in `config/file_type_definitions.json`.
+    *   `target_type`: The specific file type key from `FILE_TYPE_DEFINITIONS` (e.g., `"MAP_COL"`, `"MAP_NORM_GL"`, `"MAP_RGH"`). This replaces previous alias-based systems. The common aliases like "COL" or "NRM" are now derived from the `standard_type` property within `FILE_TYPE_DEFINITIONS` but are not used directly for `target_type`.
+    *   `keywords`: A list of filename patterns (regex or fnmatch-style wildcards) used to identify this map type. The order of keywords within this list, and the order of dictionaries in the `map_type_mapping` list, determines the priority for assigning variant suffixes (`-1`, `-2`, etc.) when multiple files match the same `target_type`.
+*   `bit_depth_variants`: A dictionary mapping standard map types (e.g., `"NRM"`) to a pattern identifying its high bit-depth variant (e.g., `"*_NRM16*.tif"`). Files matching these patterns are prioritized over their standard counterparts.
+*   `map_bit_depth_rules`: Defines how to handle the bit depth of source maps. Can specify a default behavior (`"respect"` or `"force_8bit"`) and overrides for specific map types.
+*   `model_patterns`: A list of regex patterns to identify model files (e.g., `".*\\.fbx"`, `".*\\.obj"`).
+*   `move_to_extra_patterns`: A list of regex patterns for files that should be moved directly to the `Extra/` output subdirectory without further processing.
+*   `source_naming_convention`: Rules for extracting the base asset name and potentially the archetype from source filenames or directory structures (e.g., using separators and indices).
+*   `asset_category_rules`: Keywords or patterns used to determine the asset category (e.g., identifying `"Decal"` based on keywords).
+*   `archetype_rules`: Keywords or patterns used to determine the asset archetype (e.g., identifying `"Wood"` or `"Metal"`).
+
+Careful definition of these patterns and rules, especially the regex in `map_type_mapping`, `bit_depth_variants`, `model_patterns`, and `move_to_extra_patterns`, is essential for correct asset processing.
+
+**Note on Data Passing:** As mentioned in the Architecture documentation, major changes to the data passing mechanisms between the GUI, Main (CLI orchestration), and `AssetProcessor` modules are currently being planned. The descriptions of how configuration data is handled and passed within this document reflect the current state and will require review and updates once the plan for these changes is finalized.

 ### Core Item Processing Loop
 
-The [`PipelineOrchestrator`](processing/pipeline/orchestrator.py:36) iterates through the `context.processing_items` list (populated by the [`PrepareProcessingItemsStage`](processing/pipeline/stages/prepare_processing_items.py:10)). For each item (either a [`FileRule`](rule_structure.py:5) for a regular map or a [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16) for a merged map), the following stages are executed sequentially:
+The [`PipelineOrchestrator`](processing/pipeline/orchestrator.py:36) iterates through the `context.processing_items` list (populated by the [`PrepareProcessingItemsStage`](processing/pipeline/stages/prepare_processing_items.py:10)). Each `item` in this list is now either a [`ProcessingItem`](rule_structure.py:0) (representing a specific variant of a source map, e.g., Color at 1K, or Color at LOWRES) or a [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16).
 
 1.  **[`PrepareProcessingItemsStage`](processing/pipeline/stages/prepare_processing_items.py:10)** (`processing/pipeline/stages/prepare_processing_items.py`):
-    *   **Responsibility**: (Executed once before the loop) Creates the `context.processing_items` list by combining [`FileRule`](rule_structure.py:5)s from `context.files_to_process` and [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16)s derived from the global `map_merge_rules` configuration. It correctly accesses `map_merge_rules` from `context.config_obj` and validates each merge rule for the presence of `output_map_type` and a dictionary for `inputs`. Initializes `context.intermediate_results`.
+    *   **Responsibility**: (Executed once before the loop) This stage is now responsible for "exploding" each relevant [`FileRule`](rule_structure.py:5) into one or more [`ProcessingItem`](rule_structure.py:0) objects.
-    *   **Context Interaction**: Reads from `context.files_to_process` and `context.config_obj` (accessing `map_merge_rules`). Populates `context.processing_items` and initializes `context.intermediate_results`.
+        *   For each [`FileRule`](rule_structure.py:5) that represents an image map:
+            *   It loads the source image data and determines its original dimensions and bit depth.
+            *   It creates standard [`ProcessingItem`](rule_structure.py:0)s for each required output resolution (e.g., "1K", "PREVIEW"), populating them with a copy of the source image data and the respective `resolution_key`.
+            *   If the "Low-Resolution Fallback" feature is enabled (`ENABLE_LOW_RESOLUTION_FALLBACK` in config) and the source image's largest dimension is below `LOW_RESOLUTION_THRESHOLD`, it creates an additional [`ProcessingItem`](rule_structure.py:0) with `resolution_key="LOWRES"`, using the original image data and dimensions.
+        *   It also adds [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16)s derived from global `map_merge_rules`.
+    *   **Context Interaction**: Reads `context.files_to_process` and `context.config_obj`. Populates `context.processing_items` with a list of [`ProcessingItem`](rule_structure.py:0) and [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16) objects. Initializes `context.intermediate_results`.
 
-2.  **[`RegularMapProcessorStage`](processing/pipeline/stages/regular_map_processor.py:18)** (`processing/pipeline/stages/regular_map_processor.py`):
+For each `item` in `context.processing_items`:
-    *   **Responsibility**: (Executed per [`FileRule`](rule_structure.py:5) item) Checks if the `FileRule.item_type` starts with "MAP_". If not, the item is skipped. Otherwise, it loads the image data for the file, determines its potentially suffixed internal map type (e.g., "MAP_COL-1"), applies in-memory transformations (Gloss-to-Rough, Normal Green Invert) using the shared utility function [`apply_common_map_transformations`](processing/utils/image_processing_utils.py), and returns the processed image data and details in a [`ProcessedRegularMapData`](processing/pipeline/asset_context.py:23) object. The `internal_map_type` in the output reflects any transformations (e.g., "MAP_GLOSS" becomes "MAP_ROUGH").
+
-    *   **Context Interaction**: Reads from the input [`FileRule`](rule_structure.py:5) (checking `item_type`) and [`Configuration`](configuration.py:68). Returns a [`ProcessedRegularMapData`](processing/pipeline/asset_context.py:23) object which is stored in `context.intermediate_results`.
+2.  **Transformations (Implicit or via a dedicated stage - formerly `RegularMapProcessorStage` logic):**
+    *   **Responsibility**: If the `item` is a [`ProcessingItem`](rule_structure.py:0), its `image_data` (loaded by `PrepareProcessingItemsStage`) may need transformations (Gloss-to-Rough, Normal Green Invert). This logic, previously in `RegularMapProcessorStage`, might be integrated into `PrepareProcessingItemsStage` before `ProcessingItem` creation, or handled by a new dedicated transformation stage that operates on `ProcessingItem.image_data`. The `item.map_type_identifier` would be updated if a transformation like Gloss-to-Rough occurs.
+    *   **Context Interaction**: Modifies `item.image_data` and `item.map_type_identifier` within the [`ProcessingItem`](rule_structure.py:0) object.
 
 3.  **[`MergedTaskProcessorStage`](processing/pipeline/stages/merged_task_processor.py:68)** (`processing/pipeline/stages/merged_task_processor.py`):
-    *   **Responsibility**: (Executed per [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16) item) Validates that all input map types specified in the merge rule start with "MAP_". If not, the task is failed. It dynamically loads input images by looking up the required input map types (e.g., "MAP_NRM") in `context.processed_maps_details` and using the temporary file paths from their `saved_files_info`. It applies in-memory transformations to inputs using [`apply_common_map_transformations`](processing/utils/image_processing_utils.py), handles dimension mismatches (with fallback creation if configured and `source_dimensions` are available), performs the channel merging operation, and returns the merged image data and details in a [`ProcessedMergedMapData`](processing/pipeline/asset_context.py:35) object. The `output_map_type` of the merged map must also be "MAP_" prefixed in the configuration.
+    *   **Responsibility**: (Executed if `item` is a [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16)) Same as before: validates inputs, loads source map data (likely from `ProcessingItem`s in `context.processing_items` or a cache populated from them), applies transformations, merges channels, and returns [`ProcessedMergedMapData`](processing/pipeline/asset_context.py:35).
-    *   **Context Interaction**: Reads from the input [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16) (checking input map types), `context.workspace_path`, `context.processed_maps_details` (for input image data), and [`Configuration`](configuration.py:68). Returns a [`ProcessedMergedMapData`](processing/pipeline/asset_context.py:35) object which is stored in `context.intermediate_results`.
+    *   **Context Interaction**: Reads [`MergeTaskDefinition`](processing/pipeline/asset_context.py:16), potentially `context.processing_items` (or a cache derived from it) for input image data. Returns [`ProcessedMergedMapData`](processing/pipeline/asset_context.py:35).
 
 4.  **[`InitialScalingStage`](processing/pipeline/stages/initial_scaling.py:14)** (`processing/pipeline/stages/initial_scaling.py`):
-    *   **Responsibility**: (Executed per item) Applies initial scaling (e.g., Power-of-Two downscaling) to the image data from the previous processing stage based on the `initial_scaling_mode` configuration.
+    *   **Responsibility**: (Executed per item)
-    *   **Context Interaction**: Takes a [`InitialScalingInput`](processing/pipeline/asset_context.py:46) (containing image data and config) and returns an [`InitialScalingOutput`](processing/pipeline/asset_context.py:54) object, which updates the item's entry in `context.intermediate_results`.
+        *   If `item` is a [`ProcessingItem`](rule_structure.py:0): Takes `item.image_data`, `item.current_dimensions`, and `item.resolution_key` as input. If `item.resolution_key` is "LOWRES", POT scaling is skipped. Otherwise, applies POT scaling if configured.
+        *   If `item` is from a `MergeTaskDefinition` (i.e., `processed_data` from `MergedTaskProcessorStage`): Applies POT scaling as before.
+    *   **Context Interaction**: Takes [`InitialScalingInput`](processing/pipeline/asset_context.py:46) (now including `resolution_key`). Returns [`InitialScalingOutput`](processing/pipeline/asset_context.py:54) (also including `resolution_key`), which updates `context.intermediate_results`. The `current_image_data` and `current_dimensions` for saving are taken from this output.
 
 5.  **[`SaveVariantsStage`](processing/pipeline/stages/save_variants.py:15)** (`processing/pipeline/stages/save_variants.py`):
-    *   **Responsibility**: (Executed per item) Takes the final processed image data (potentially scaled) and configuration, and calls a utility to save the image to temporary files in various resolutions and formats as defined by the configuration.
+    *   **Responsibility**: (Executed per item) Saves the (potentially scaled) `current_image_data`.
-    *   **Context Interaction**: Takes a [`SaveVariantsInput`](processing/pipeline/asset_context.py:61) object (which includes the "MAP_" prefixed `internal_map_type`). It uses the `get_filename_friendly_map_type` utility to convert this to a "standard type" (e.g., "COL") for output naming. Returns a [`SaveVariantsOutput`](processing/pipeline/asset_context.py:79) object containing details about the saved temporary files. The orchestrator stores these details, including the original "MAP_" prefixed `internal_map_type`, in `context.processed_maps_details` for the item.
+    *   **Context Interaction**:
+        *   Takes [`SaveVariantsInput`](processing/pipeline/asset_context.py:61).
+        *   `internal_map_type` is set from `item.map_type_identifier` (for `ProcessingItem`) or `processed_data.output_map_type` (for merged).
+        *   `output_filename_pattern_tokens['resolution']` is set to the `resolution_key` obtained from `scaled_data_output.resolution_key` (which originates from `item.resolution_key` for `ProcessingItem`s, or is `None` for merged items that get all standard resolutions).
+        *   `image_resolutions` argument for `SaveVariantsInput`:
+            *   If `resolution_key == "LOWRES"`: Set to `{"LOWRES": width_of_lowres_data}`.
+            *   If `resolution_key` is a standard key (e.g., "1K"): Set to `{resolution_key: configured_dimension}`.
+            *   For merged items (where `resolution_key` from scaling is likely `None`): Set to the full `config.image_resolutions` map to generate all applicable standard sizes.
+        *   Returns [`SaveVariantsOutput`](processing/pipeline/asset_context.py:79). Orchestrator stores details in `context.processed_maps_details`.

+# Code Review & Refactoring Plan: GUI File Table
+
+**Objective:** To identify the root causes of file list discrepancies and persistent empty asset rows in the GUI file table, and to propose refactoring solutions for improved robustness and maintainability.
+
+**Phase 1: In-Depth Code Review**
+
+This phase will focus on understanding the current implementation and data flow within the relevant GUI modules.
+
+1.  **Identify Key Modules & Classes:**
+    *   **`gui/unified_view_model.py` ([`UnifiedViewModel`](gui/unified_view_model.py:1)):** This is the primary focus. We need to analyze:
+        *   How it loads and represents the hierarchical data (`SourceRule` -> `AssetRule` -> `FileRule`).
+        *   Methods responsible for updating the model with new data (e.g., from predictions or user edits).
+        *   Logic for adding, removing, and modifying rows, especially `AssetRule` and `FileRule` items.
+        *   How it handles data consistency when underlying data changes (e.g., after LLM processing or renaming operations).
+        *   Signal/slot connections related to data changes.
+    *   **`gui/asset_restructure_handler.py` ([`AssetRestructureHandler`](gui/asset_restructure_handler.py:1)):**
+        *   How it listens to changes in `AssetRule` names or `FileRule` target asset overrides.
+        *   The logic for moving `FileRule` items between `AssetRule` items.
+        *   The conditions under which it creates new `AssetRule` items or removes empty ones. This is critical for the "persistent empty asset rows" issue.
+    *   **`gui/llm_prediction_handler.py` ([`LLMPredictionHandler`](gui/llm_prediction_handler.py:1)):**
+        *   How it parses the LLM response.
+        *   How it translates the LLM's (potentially hallucinated) file list into the `SourceRule` structure.
+        *   How this new `SourceRule` data is passed to and integrated by the `UnifiedViewModel`. This is key for the "file list discrepancies" issue.
+    *   **`gui/prediction_handler.py` ([`RuleBasedPredictionHandler`](gui/prediction_handler.py:1)):**
+        *   Similar to the LLM handler, how it generates `SourceRule` data from presets.
+        *   How its output is integrated into the `UnifiedViewModel`, especially when "reinterpreting with a systematic approach" restores correct files.
+    *   **`gui/main_window.py` ([`MainWindow`](gui/main_window.py:1)) & `gui/main_panel_widget.py` ([`MainPanelWidget`](gui/main_panel_widget.py:1)):**
+        *   How these components instantiate and connect the `UnifiedViewModel`, `AssetRestructureHandler`, and prediction handlers.
+        *   Event handling related to loading data, triggering predictions, and user interactions that modify the table data.
+    *   **`rule_structure.py`:**
+        *   Review the definitions of `SourceRule`, `AssetRule`, and `FileRule` to ensure a clear understanding of the data being managed.
+
+2.  **Trace Data Flow & State Management:**
+    *   **Initial Load:** How is the initial list of files/assets loaded and represented in the `UnifiedViewModel`?
+    *   **LLM Processing:**
+        *   Trace the data flow from the LLM response -> `LLMPredictionHandler` -> `UnifiedViewModel`.
+        *   How does the `UnifiedViewModel` reconcile the LLM's version of the file list with any existing state? Is there a clear "source of truth" for the file list before and after LLM processing?
+    *   **Preset-Based Processing:**
+        *   Trace data flow from preset selection -> `RuleBasedPredictionHandler` -> `UnifiedViewModel`.
+        *   How does this "systematic approach" correct discrepancies? Does it fully replace the model's data or merge it?
+    *   **Renaming/Restructuring:**
+        *   Trace the events and actions from a user renaming an asset -> `AssetRestructureHandler` -> `UnifiedViewModel`.
+        *   How are `AssetRule` items checked for emptiness and subsequently removed (or not removed)?
+
+3.  **Analyze Event Handling and Signal/Slot Connections:**
+    *   Map out the key signals and slots between the `UnifiedViewModel`, `AssetRestructureHandler`, prediction handlers, and the main UI components.
+    *   Ensure that signals are emitted and slots are connected correctly to trigger necessary updates and prevent race conditions or missed updates.
+
+**Phase 2: Identify Issues & Propose Refactoring Strategies**
+
+Based on the review, we will pinpoint specific areas contributing to the reported problems and suggest improvements.
+
+1.  **For File List Discrepancies (especially post-LLM):**
+    *   **Potential Issue:** The `UnifiedViewModel` might be directly replacing its internal data with the LLM's output without proper validation or merging against the original input file list.
+    *   **Proposed Strategy:**
+        *   Establish a clear "source of truth" for the actual input files that remains independent of the LLM's interpretation.
+        *   When the LLM provides its categorized list, the `LLMPredictionHandler` or `UnifiedViewModel` should *map* the LLM's findings onto the *existing* source files rather than creating a new list from scratch based on LLM hallucinations.
+        *   If the LLM identifies files not in the original input, these should be flagged or handled as discrepancies, not added as if they were real.
+        *   If the LLM *misses* files from the original input, these should remain visible, perhaps marked as "uncategorized by LLM."
+
+2.  **For Persistent Empty Asset Rows:**
+    *   **Potential Issue:** The `AssetRestructureHandler`'s logic for detecting and removing empty `AssetRule` items might be flawed or not consistently triggered. It might not correctly count child `FileRule` items after a move, or the signal to check for emptiness might not always fire.
+    *   **Proposed Strategy:**
+        *   Review and strengthen the logic within `AssetRestructureHandler` that checks if an `AssetRule` is empty after its `FileRule` children are moved or its name changes.
+        *   Ensure that this check is reliably performed *after* all relevant model updates have completed.
+        *   Consider adding explicit methods to `UnifiedViewModel` or `AssetRule` to query if an asset group is truly empty (has no associated `FileRule` items).
+        *   Ensure that the `UnifiedViewModel` correctly emits signals that the `AssetRestructureHandler` can use to trigger cleanup of empty asset rows.
+
+3.  **General Robustness & Maintainability:**
+    *   **State Management:** Clarify state management within `UnifiedViewModel`. Ensure data consistency and minimize side effects.
+    *   **Modularity:** Ensure clear separation of concerns between the `UnifiedViewModel` (data representation), prediction handlers (data generation), and `AssetRestructureHandler` (data manipulation).
+    *   **Logging & Error Handling:** Improve logging in these critical sections to make troubleshooting easier. Add robust error handling for unexpected data states.
+    *   **Unit Tests:** Identify areas where unit tests could be added or improved to cover the scenarios causing these bugs, especially around model updates and restructuring.
+
+**Phase 3: Documentation & Handoff**
+
+1.  Document the findings of the code review.
+2.  Detail the agreed-upon refactoring plan.
+3.  Prepare for handoff to a developer (e.g., by switching to "Code" mode).

+# Configuration System Refactoring Plan
+
+This document outlines the plan for refactoring the configuration system of the Asset Processor Tool.
+
+## Overall Goals
+
+1.  **Decouple Definitions:** Separate `ASSET_TYPE_DEFINITIONS` and `FILE_TYPE_DEFINITIONS` from the main `config/app_settings.json` into dedicated files.
+2.  **Introduce User Overrides:** Allow users to override base settings via a new `config/user_settings.json` file.
+3.  **Improve GUI Saving:** (Lower Priority) Make GUI configuration saving more targeted to avoid overwriting unrelated settings when saving changes from `ConfigEditorDialog` or `LLMEditorWidget`.
+
+## Proposed Plan Phases
+
+**Phase 1: Decouple Definitions**
+
+1.  **Create New Definition Files:**
+    *   Create `config/asset_type_definitions.json`.
+    *   Create `config/file_type_definitions.json`.
+2.  **Migrate Content:**
+    *   Move `ASSET_TYPE_DEFINITIONS` object from `config/app_settings.json` to `config/asset_type_definitions.json`.
+    *   Move `FILE_TYPE_DEFINITIONS` object from `config/app_settings.json` to `config/file_type_definitions.json`.
+3.  **Update `configuration.py`:**
+    *   Add constants for new definition file paths.
+    *   Modify `Configuration` class to load these new files.
+    *   Update property methods (e.g., `get_asset_type_definitions`, `get_file_type_definitions_with_examples`) to use data from the new definition dictionaries.
+    *   Adjust validation (`_validate_configs`) as needed.
+4.  **Update GUI & `load_base_config()`:**
+    *   Modify `load_base_config()` to load and return a combined dictionary including `app_settings.json` and the two new definition files.
+    *   Update GUI components relying on `load_base_config()` to ensure they receive the necessary definition data.
+
+**Phase 2: Implement User Overrides**
+
+1.  **Define `user_settings.json`:**
+    *   Establish `config/user_settings.json` for user-specific overrides, mirroring parts of `app_settings.json`.
+2.  **Update `configuration.py` Loading:**
+    *   In `Configuration.__init__`, load `app_settings.json`, then definition files, then attempt to load and deep merge `user_settings.json` (user settings override base).
+    *   Load presets *after* the base+user merge (presets override combined base+user).
+    *   Modify `load_base_config()` to also load and merge `user_settings.json` after `app_settings.json`.
+3.  **Update GUI Editors:**
+    *   Modify `ConfigEditorDialog` to load the effective settings (base+user) but save changes *only* to `config/user_settings.json`.
+    *   `LLMEditorWidget` continues targeting `llm_settings.json`.
+
+**Phase 3: Granular GUI Saving (Lower Priority)**
+
+1.  **Refactor Saving Logic:**
+    *   In `ConfigEditorDialog` and `LLMEditorWidget`:
+        *   Load the current target file (`user_settings.json` or `llm_settings.json`).
+        *   Identify specific setting(s) changed by the user in the GUI session.
+        *   Update only those specific key(s) in the loaded dictionary.
+        *   Write the entire modified dictionary back to the target file, preserving untouched settings.

-# Plan: Enforcing "MAP_" Prefix for Internal Processing and Standard Type for Output Naming
-
-**Date:** 2025-05-13
-
-**I. Goal:**
-The primary goal is to ensure that for all internal processing, the system *exclusively* uses `FileRule.item_type` values that start with the "MAP_" prefix (e.g., "MAP_COL", "MAP_NRM"). The "standard type" (e.g., "COL", "NRM") associated with these "MAP_" types (as defined in `config/app_settings.json`) should *only* be used during the file saving stages for output naming. Any `FileRule` whose `item_type` does not start with "MAP_" (and isn't a special type like "EXTRA" or "MODEL") should be skipped by the relevant map processing stages.
-
-**II. Current State Analysis Summary:**
-
-*   **Output Naming:** The use of "standard type" for output filenames via the `get_filename_friendly_map_type` utility in `SaveVariantsStage` and `OutputOrganizationStage` is **correct** and already meets the requirement.
-*   **Internal "MAP_" Prefix Usage:**
-    *   Some stages like `GlossToRoughConversionStage` correctly check for "MAP_" prefixes (e.g., `processing_map_type.startswith("MAP_GLOSS")`).
-    *   Other stages like `RegularMapProcessorStage` and `MergedTaskProcessorStage` (and its helpers) implicitly expect "MAP_" prefixed types for their internal regex-based logic but lack explicit checks to skip items if the prefix is missing.
-    *   Stages like `AlphaExtractionToMaskStage` and `NormalMapGreenChannelStage` currently use non-"MAP_" prefixed "standard types" (e.g., "NORMAL", "ALBEDO") when reading from `context.processed_maps_details` for their decision-making logic.
-    *   The `PrepareProcessingItemsStage` adds `FileRule`s to the processing queue without filtering based on the "MAP_" prefix in `item_type`.
-*   **Data Consistency in `AssetProcessingContext`:**
-    *   `FileRule.item_type` is the field that should hold the "MAP_" prefixed type from the initial rule generation.
-    *   `context.processed_maps_details` entries can contain various map type representations:
-        *   `map_type`: Often stores the "standard type" (e.g., "Roughness", "MASK", "NORMAL").
-        *   `processing_map_type` / `internal_map_type`: Generally seem to store the "MAP_" prefixed type. This needs to be consistent.
-*   **Configuration (`config/app_settings.json`):**
-    *   `FILE_TYPE_DEFINITIONS` correctly use "MAP_" prefixed keys.
-    *   `MAP_MERGE_RULES` need to be reviewed to ensure their `output_map_type` and input map types are "MAP_" prefixed.
-
-**III. Proposed Changes (Code Identification & Recommendations):**
-
-**A. Enforce "MAP_" Prefix for Processing Items (Skipping Logic):**
-The core requirement is that processing stages should skip `FileRule` items if their `item_type` doesn't start with "MAP_".
-
-1.  **`RegularMapProcessorStage` (`processing/pipeline/stages/regular_map_processor.py`):**
-    *   **Identify:** In the `execute` method, `initial_internal_map_type` is derived from `file_rule.item_type_override` or `file_rule.item_type`.
-    *   **Recommend:** Add an explicit check after determining `initial_internal_map_type`. If `initial_internal_map_type` does not start with `"MAP_"`, the stage should log a warning, set the `result.status` to "Skipped (Invalid Type)" or similar, and return `result` early, effectively skipping processing for this item.
-
-2.  **`MergedTaskProcessorStage` (`processing/pipeline/stages/merged_task_processor.py`):**
-    *   **Identify:** This stage processes `MergeTaskDefinition`s. The definitions for these tasks (input types, output type) come from `MAP_MERGE_RULES` in `config/app_settings.json`. The stage uses `required_map_type_from_rule` for its inputs.
-    *   **Recommend:**
-        *   **Configuration First:** Review all entries in `MAP_MERGE_RULES` in `config/app_settings.json`.
-            *   Ensure the `output_map_type` for each rule (e.g., "MAP_NRMRGH") starts with "MAP_".
-            *   Ensure all map type values within the `inputs` dictionary (e.g., `"R": "MAP_NRM"`) start with "MAP_".
-        *   **Stage Logic:** In the `execute` method, when iterating through `merge_inputs_config.items()`, check if `required_map_type_from_rule` starts with `"MAP_"`. If not, log a warning and either:
-            *   Skip loading/processing this specific input channel (potentially using its fallback if the overall merge can still proceed).
-            *   Or, if a non-"MAP_" input is critical, fail the entire merge task for this asset.
-        *   The helper `_apply_in_memory_transformations` already uses regex expecting "MAP_" prefixes; this will naturally fail or misbehave if inputs are not "MAP_" prefixed, reinforcing the need for the check above.
-
-**B. Standardize Map Type Fields and Usage in `context.processed_maps_details`:**
-Ensure consistency in how "MAP_" prefixed types are stored and accessed within `context.processed_maps_details` for internal logic (not naming).
-
-1.  **Recommendation:** Establish a single, consistent field name within `context.processed_maps_details` to store the definitive "MAP_" prefixed internal map type (e.g., `internal_map_type` or `processing_map_type`). All stages that perform logic based on the specific *kind* of map (e.g., transformations, source selection) should read from this standardized field. The `map_type` field can continue to store the "standard type" (e.g., "Roughness") primarily for informational/metadata purposes if needed, but not for core processing logic.
-
-2.  **`AlphaExtractionToMaskStage` (`processing/pipeline/stages/alpha_extraction_to_mask.py`):**
-    *   **Identify:**
-        *   Checks for existing MASK map using `file_rule.map_type == "MASK"`. (Discrepancy: `FileRule` uses `item_type`).
-        *   Searches for suitable source maps using `details.get('map_type') in self.SUITABLE_SOURCE_MAP_TYPES` where `SUITABLE_SOURCE_MAP_TYPES` are standard types like "ALBEDO".
-        *   When adding new details, it sets `map_type: "MASK"` and the new `FileRule` gets `item_type="MAP_MASK"`.
-    *   **Recommend:**
-        *   Change the check for an existing MASK map to `file_rule.item_type == "MAP_MASK"`.
-        *   Modify the source map search to use the standardized "MAP_" prefixed field from `details` (e.g., `details.get('internal_map_type')`) and update `SUITABLE_SOURCE_MAP_TYPES` to be "MAP_" prefixed (e.g., "MAP_COL", "MAP_ALBEDO").
-        *   When adding new details for the created MASK map to `context.processed_maps_details`, ensure the standardized "MAP_" prefixed field is set to "MAP_MASK", and `map_type` (if kept) is "MASK".
-
-3.  **`NormalMapGreenChannelStage` (`processing/pipeline/stages/normal_map_green_channel.py`):**
-    *   **Identify:** Checks `map_details.get('map_type') == "NORMAL"`.
-    *   **Recommend:** Change this check to use the standardized "MAP_" prefixed field from `map_details` (e.g., `map_details.get('internal_map_type')`) and verify if it `startswith("MAP_NRM")`.
-
-4.  **`GlossToRoughConversionStage` (`processing/pipeline/stages/gloss_to_rough_conversion.py`):**
-    *   **Identify:** This stage already uses `processing_map_type.startswith("MAP_GLOSS")` and updates `processing_map_type` to "MAP_ROUGH" in `map_details`. It also updates the `FileRule.item_type` correctly.
-    *   **Recommend:** This stage is largely consistent. Ensure the field it reads/writes (`processing_map_type`) aligns with the chosen standardized "MAP_" prefixed field for `processed_maps_details`.
-
-**C. Review Orchestration Logic (Conceptual):**
-*   When the orchestrator populates `context.processed_maps_details` after stages like `SaveVariantsStage`, ensure it stores the "MAP_" prefixed `internal_map_type` (from `SaveVariantsInput`) into the chosen standardized field in `processed_maps_details`.
-
-**IV. Testing Recommendations:**
-
-*   Create test cases with `AssetRule`s containing `FileRule`s where `item_type` is intentionally set to a non-"MAP_" prefixed value (e.g., "COLOR_MAP", "TEXTURE_ROUGH"). Verify that `RegularMapProcessorStage` skips these.
-*   Modify `MAP_MERGE_RULES` in a test configuration:
-    *   Set an `output_map_type` to a non-"MAP_" value.
-    *   Set an input map type (e.g., for channel "R") to a non-"MAP_" value.
-    *   Verify that `MergedTaskProcessorStage` correctly handles these (e.g., fails the task, skips the input, logs warnings).
-*   Test `AlphaExtractionToMaskStage`:
-    *   With an existing `FileRule` having `item_type="MAP_MASK"` to ensure extraction is skipped.
-    *   With source maps having "MAP_COL" (with alpha) as their `internal_map_type` in `processed_maps_details` to ensure they are correctly identified as sources.
-*   Test `NormalMapGreenChannelStage` with a normal map having "MAP_NRM" as its `internal_map_type` in `processed_maps_details` to ensure it's processed.
-*   Verify that output filenames continue to use the "standard type" (e.g., "COL", "ROUGH", "NRM") correctly.

-# Processing Pipeline Refactoring Plan
-
-## 1. Problem Summary
-
-The current processing pipeline, particularly the `IndividualMapProcessingStage`, exhibits maintainability challenges:
-
-*   **High Complexity:** The stage handles too many responsibilities (loading, merging, transformations, scaling, saving).
-*   **Duplicated Logic:** Image transformations (Gloss-to-Rough, Normal Green Invert) are duplicated within the stage instead of relying solely on dedicated stages or being handled consistently.
-*   **Tight Coupling:** Heavy reliance on the large, mutable `AssetProcessingContext` object creates implicit dependencies and makes isolated testing difficult.
-
-## 2. Refactoring Goals
-
-*   Improve code readability and understanding.
-*   Enhance maintainability by localizing changes and removing duplication.
-*   Increase testability through smaller, focused components with clear interfaces.
-*   Clarify data dependencies between pipeline stages.
-*   Adhere more closely to the Single Responsibility Principle (SRP).
-
-## 3. Proposed New Pipeline Stages
-
-Replace the existing `IndividualMapProcessingStage` with the following sequence of smaller, focused stages, executed by the `PipelineOrchestrator` for each processing item:
-
-1.  **`PrepareProcessingItemsStage`:**
-    *   **Responsibility:** Identifies and lists all items (`FileRule`, `MergeTaskDefinition`) to be processed from the main context.
-    *   **Output:** Updates `context.processing_items`.
-
-2.  **`RegularMapProcessorStage`:** (Handles `FileRule` items)
-    *   **Responsibility:** Loads source image, determines internal map type (with suffix), applies relevant transformations (Gloss-to-Rough, Normal Green Invert), determines original metadata.
-    *   **Output:** `ProcessedRegularMapData` object containing transformed image data and metadata.
-
-3.  **`MergedTaskProcessorStage`:** (Handles `MergeTaskDefinition` items)
-    *   **Responsibility:** Loads input images, applies transformations to inputs, handles fallbacks/resizing, performs merge operation.
-    *   **Output:** `ProcessedMergedMapData` object containing merged image data and metadata.
-
-4.  **`InitialScalingStage`:** (Optional)
-    *   **Responsibility:** Applies configured scaling (e.g., POT downscale) to the processed image data received from the previous stage.
-    *   **Output:** Scaled image data.
-
-5.  **`SaveVariantsStage`:**
-    *   **Responsibility:** Takes the final processed (and potentially scaled) image data and orchestrates saving variants using the `save_image_variants` utility.
-    *   **Output:** List of saved file details (`saved_files_details`).
-
-## 4. Proposed Data Flow
-
-*   **Input/Output Objects:** Key stages (`RegularMapProcessor`, `MergedTaskProcessor`, `InitialScaling`, `SaveVariants`) will use specific Input and Output dataclasses for clearer interfaces.
-*   **Orchestrator Role:** The `PipelineOrchestrator` manages the overall flow. It calls stages, passes necessary data (extracting image data references and metadata from previous stage outputs to create inputs for the next), receives output objects, and integrates final results (like saved file details) back into the main `AssetProcessingContext`.
-*   **Image Data Handling:** Large image arrays (`np.ndarray`) are passed primarily via stage return values (Output objects) and used as inputs to subsequent stages, managed by the Orchestrator. They are not stored long-term in the main `AssetProcessingContext`.
-*   **Main Context:** The `AssetProcessingContext` remains for overall state (rules, paths, configuration access, final status tracking) and potentially for simpler stages with minimal side effects.
-
-## 5. Visualization (Conceptual)
-
-```mermaid
-graph TD
-    subgraph Proposed Pipeline Stages
-        Start --> Prep[PrepareProcessingItemsStage]
-        Prep --> ItemLoop{Loop per Item}
-        ItemLoop -- FileRule --> RegProc[RegularMapProcessorStage]
-        ItemLoop -- MergeTask --> MergeProc[MergedTaskProcessorStage]
-        RegProc --> Scale(InitialScalingStage)
-        MergeProc --> Scale
-        Scale --> Save[SaveVariantsStage]
-        Save --> UpdateContext[Update Main Context w/ Results]
-        UpdateContext --> ItemLoop
-    end
-```
-
-## 6. Benefits
-
-*   Improved Readability & Understanding.
-*   Enhanced Maintainability & Reduced Risk.
-*   Better Testability.
-*   Clearer Dependencies.

+# Bit Depth Terminology Refactoring Plan
+
+## 1. Background
+
+Currently, there's an inconsistency in how bit depth rules and settings are defined and used across the project:
+
+*   **`config/file_type_definitions.json`**: Uses `"bit_depth_rule"` with values like `"force_8bit"` and `"respect"`.
+*   **`config/app_settings.json`**: (Within `MAP_MERGE_RULES`) uses `"output_bit_depth"` with values like `"respect_inputs"`.
+*   **`processing/utils/image_saving_utils.py`**: Contains logic that attempts to handle `"respect_inputs"` but is currently unreachable, and the `"respect"` rule effectively defaults to 8-bit.
+
+This plan aims to unify the terminology and correct the processing logic.
+
+## 2. Proposed Unified Terminology
+
+A new configuration key and a clear set of values will be adopted:
+
+*   **New Key**: `bit_depth_policy`
+    *   This key will replace `"bit_depth_rule"` in `file_type_definitions.json`.
+    *   This key will replace `"output_bit_depth"` in `app_settings.json` (for `MAP_MERGE_RULES`).
+*   **Values for `bit_depth_policy`**:
+    *   `"force_8bit"`: Always output 8-bit.
+    *   `"force_16bit"`: Always output 16-bit.
+    *   `"preserve"`: If any source image (or any input to a merge operation) has a bit depth greater than 8-bit, the output will be 16-bit. Otherwise, the output will be 8-bit.
+    *   `""` (empty string or `null`): No specific bit depth policy applies (e.g., for non-image files like models or text files).
+
+## 3. Refactoring Plan Details
+
+### Phase 1: Configuration File Updates
+
+1.  **`config/file_type_definitions.json`**:
+    *   Rename all instances of the key `"bit_depth_rule"` to `"bit_depth_policy"`.
+    *   Update values:
+        *   `"force_8bit"` remains `"force_8bit"`.
+        *   `"respect"` changes to `"preserve"`.
+        *   `""` (empty string) remains `""`.
+2.  **`config/app_settings.json`**:
+    *   Within each rule in the `MAP_MERGE_RULES` array, rename the key `"output_bit_depth"` to `"bit_depth_policy"`.
+    *   Update the value: `"respect_inputs"` changes to `"preserve"`.
+
+### Phase 2: Code Update - `configuration.py`
+
+1.  Modify the `Configuration` class:
+    *   Rename the method `get_bit_depth_rule()` to `get_bit_depth_policy()`.
+    *   Update this method to read the new `"bit_depth_policy"` key from the loaded file type definitions.
+    *   Ensure it correctly handles and returns the new policy values (`"force_8bit"`, `"force_16bit"`, `"preserve"`, `""`).
+    *   The method should continue to provide a sensible default if a map type is not found or has an invalid policy.
+
+### Phase 3: Code Update - `processing/utils/image_saving_utils.py`
+
+1.  Refactor the `save_image_variants` function:
+    *   It will receive the `bit_depth_policy` (e.g., `"preserve"`, `"force_8bit"`) via its `file_type_defs` argument (which originates from the `Configuration` object).
+    *   Correct the internal logic for determining `target_bit_depth` based on the `bit_depth_policy` argument:
+        *   If `bit_depth_policy == "force_8bit"`, then `target_bit_depth = 8`.
+        *   If `bit_depth_policy == "force_16bit"`, then `target_bit_depth = 16`.
+        *   If `bit_depth_policy == "preserve"`:
+            *   Examine the `source_bit_depth_info` argument (list of bit depths of input images).
+            *   If any source bit depth in `source_bit_depth_info` is greater than 8, then `target_bit_depth = 16`.
+            *   Otherwise (all source bit depths are 8 or less, or list is empty/all None), `target_bit_depth = 8`.
+        *   If `bit_depth_policy == ""` or is `null` (or any other unhandled value), a clear default behavior should be established (e.g., log a warning and default to `"preserve"` or skip bit depth adjustments if appropriate for the file type).
+
+### Phase 4: Code Update - `processing/pipeline/stages/merged_task_processor.py`
+
+1.  This stage is largely unaffected in its core logic for collecting `input_source_bit_depths`.
+2.  The `ProcessedMergedMapData` object it produces will continue to carry these `source_bit_depths`.
+3.  When this data is later passed to the `SaveVariantsStage` (and subsequently to `save_image_variants`), the `internal_map_type` of the merged map (e.g., "MAP_NRMRGH") will be used. The `Configuration` object will provide its `bit_depth_policy` (which, after refactoring `file_type_definitions.json`, should be `"preserve"` for relevant merged maps).
+4.  The refactored `save_image_variants` will then use this `"preserve"` policy along with the `source_bit_depth_info` (derived from the merge inputs) to correctly determine the output bit depth for the merged map.
+
+### Phase 5: Review Other Code & Potential Impacts
+
+1.  Conduct a codebase search for any remaining direct usages of the old keys (`"bit_depth_rule"`, `"output_bit_depth"`) or their values.
+2.  Update these locations to use the new `Configuration.get_bit_depth_policy()` method and the new `"bit_depth_policy"` key and values.
+3.  Pay special attention to any prediction logic (e.g., in `gui/prediction_handler.py` or `gui/llm_prediction_handler.py`) if it currently considers or tries to infer bit depth rules.
+
+## 4. Backward Compatibility & Migration
+
+*   This is a breaking change for existing user-customized configuration files (`file_type_definitions.json`, `app_settings.json`, and any custom presets).
+*   **Recommended Approach**: Implement migration logic within the `Configuration` class's loading methods.
+    *   When loading `file_type_definitions.json`: If `"bit_depth_rule"` is found, convert its value (e.g., `"respect"` to `"preserve"`) and store it under the new `"bit_depth_policy"` key. Log a warning.
+    *   When loading `app_settings.json` (specifically `MAP_MERGE_RULES`): If `"output_bit_depth"` is found, convert its value (e.g., `"respect_inputs"` to `"preserve"`) and store it under `"bit_depth_policy"`. Log a warning.
+    *   This ensures the application can still function with older user configs while guiding users to update.

+# Issue: List item selection not working in Definitions Editor
+
+**Date:** 2025-05-13
+
+**Affected File:** [`gui/definitions_editor_dialog.py`](gui/definitions_editor_dialog.py)
+
+**Problem Description:**
+User mouse clicks on items within the `QListWidget` instances (for Asset Types, File Types, and Suppliers) in the Definitions Editor dialog do not trigger item selection or the `currentItemChanged` signal. The first item is selected by default and its details are displayed correctly. Programmatic selection of items (e.g., via a diagnostic button) *does* correctly trigger the `currentItemChanged` signal and updates the UI detail views. The issue is specific to user-initiated mouse clicks for selection after the initial load.
+
+**Debugging Steps Taken & Findings:**
+
+1.  **Initial Analysis:**
+    *   Reviewed GUI internals documentation ([`Documentation/02_Developer_Guide/06_GUI_Internals.md`](Documentation/02_Developer_Guide/06_GUI_Internals.md)) and [`gui/definitions_editor_dialog.py`](gui/definitions_editor_dialog.py) source code.
+    *   Confirmed signal connections (`currentItemChanged` to display slots) are made.
+
+2.  **Logging in Display Slots (`_display_*_details`):**
+    *   Added logging to display slots. Confirmed they are called for the initial (default) item selection.
+    *   No further calls to these slots occur on user clicks, indicating `currentItemChanged` is not firing.
+
+3.  **Color Swatch Palette Role:**
+    *   Investigated and corrected `QPalette.ColorRole` for color swatches (reverted from `Background` to `Window`). This fixed an `AttributeError` but did not resolve the selection issue.
+
+4.  **Robust Error Handling in Display Slots:**
+    *   Wrapped display slot logic in `try...finally` blocks with detailed logging. Confirmed slots complete without error for initial selection and signals for detail widgets are reconnected.
+
+5.  **Diagnostic Lambda for `currentItemChanged`:**
+    *   Added a lambda logger to `currentItemChanged` alongside the main display slot.
+    *   Confirmed both lambda and display slot fire for initial programmatic selection.
+    *   Neither fires for subsequent user clicks. This proved the `QListWidget` itself was not emitting the signal.
+
+6.  **Explicit `setEnabled` and `setSelectionMode` on `QListWidget`:**
+    *   Explicitly set these properties. No change in behavior.
+
+7.  **Explicit `setEnabled` and `setFocusPolicy(Qt.ClickFocus)` on `tab_page` (parent of `QListWidget` layout):**
+    *   This change **allowed programmatic selection via a diagnostic button to correctly fire `currentItemChanged` and update the UI**.
+    *   However, user mouse clicks still did not work and did not fire the signal.
+
+8.  **Event Filter Investigation:**
+    *   **Filter on `QListWidget`:** Did NOT receive mouse press/release events from user clicks.
+    *   **Filter on `tab_page` (parent of `QListWidget`'s layout):** Did NOT receive mouse press/release events.
+    *   **Filter on `self.tab_widget` (QTabWidget):** DID receive mouse press/release events.
+    *   Modified `self.tab_widget`'s event filter to return `False` for events over the current page, attempting to ensure propagation.
+    *   **Result:** With the modified `tab_widget` filter, an event filter re-added to `asset_type_list_widget` *did* start receiving mouse press/release events. **However, `asset_type_list_widget` still did not emit `currentItemChanged` from these user clicks.**
+
+9.  **`DebugListWidget` (Subclassing `QListWidget`):**
+    *   Created `DebugListWidget` overriding `mousePressEvent` with logging.
+    *   Used `DebugListWidget` for `asset_type_list_widget`.
+    *   **Initial user report indicated that `DebugListWidget.mousePressEvent` logs were NOT appearing for user clicks.** This means that even with the `QTabWidget` event filter attempting to propagate events, and the `asset_type_list_widget`'s filter (from step 8) confirming it received them, the `mousePressEvent` of the `QListWidget` itself was not being triggered by those propagated events. This is the current mystery.
+
+**Current Status:**
+- Programmatic selection works and fires signals.
+- User clicks are received by an event filter on `asset_type_list_widget` (after `QTabWidget` filter modification) but do not result in `mousePressEvent` being called on the `QListWidget` (or `DebugListWidget`) itself, and thus no `currentItemChanged` signal is emitted.
+- The issue seems to be a very low-level event processing problem specifically for user mouse clicks within the `QListWidget` instances when they are children of the `QTabWidget` pages, even when events appear to reach the list widget via an event filter.
+
+**Next Steps (When Resuming):**
+1.  Re-verify the logs from the `DebugListWidget.mousePressEvent` test. If it's truly not being called despite its event filter seeing events, this is extremely unusual.
+2.  Simplify the `_create_tab_pane` method drastically for one tab:
+    *   Remove the right-hand pane.
+    *   Add the `DebugListWidget` directly to the `tab_page`'s layout without the intermediate `left_pane_layout`.
+3.  Consider if any styles applied to `QListWidget` or its parents via stylesheets could be interfering with hit testing or event processing (unlikely for this specific symptom, but possible).
+4.  Explore alternative ways to populate/manage the `QListWidget` or its items if a subtle corruption is occurring.
+5.  If all else fails, consider replacing the `QListWidget` with a `QListView` and a `QStringListModel` as a more fundamental change to see if the issue is specific to `QListWidget` in this context.

Your task is to analyze a list of file paths, understand their relationships based on naming and directory structure, and output a structured JSON object that classifies each file individually and then classifies the logical asset groups they belong to.\\n\\nDefinitions:\\n\\nAsset Types: These define the overall category of a logical asset group. Use one of the following keys when classifying asset groups. Each definition is provided as a formatted string (e.g., 'Surface = A single PBR material set..., examples: WoodFloor01, MetalPlate05'):\\n{ASSET_TYPE_DEFINITIONS}\\n\\n\\nFile Types: These define the specific purpose of each individual file. Use one of the following keys when classifying individual files. Each definition is provided as a formatted string (e.g., 'MAP_COL = Color/Albedo Map, examples: _col., _basecolor.'):\\n{FILE_TYPE_DEFINITIONS}\\n\\n\\nCore Task & Logic:\\n\\n1.  **Individual File Analysis:**\\n    *   Examine each `relative_file_path` in the input `FILE_LIST`.\\n    *   For EACH file, determine its most likely `classified_file_type` using the `FILE_TYPE_DEFINITIONS`. Pay attention to filename suffixes, keywords, and extensions. Use `FILE_IGNORE` for files like `Thumbs.db` or `.DS_Store`. Use `EXTRA` for previews, metadata, or unidentifiable maps.\\n    *   For EACH file, propose a logical `proposed_asset_group_name` (string). This name should represent the asset the file likely belongs to, based on common base names (e.g., `WoodFloor01` from `WoodFloor01_col.png`, `WoodFloor01_nrm.png`) or directory structure (e.g., `SciFi_Drone` for files within that folder).\\n        *   Files that seem to be standalone utility maps (like `scratches.png`, `FlowMap.tif`) should get a unique group name derived from their filename (e.g., `Scratches`, `FlowMap`).\\n        *   If a file doesn't seem to belong to any logical group (e.g., a stray readme file in the root), you can propose `null` or a generic name like `Miscellaneous`.\\n        *   Be consistent with the proposed names for files belonging to the same logical asset.\\n    *   Populate the `individual_file_analysis` array with one object for *every* file in the input list, containing `relative_file_path`, `classified_file_type`, and `proposed_asset_group_name`.\\n\\n2.  **Asset Group Classification:**\\n    *   Collect all unique, non-null `proposed_asset_group_name` values generated in the previous step.\\n    *   For EACH unique group name, determine the overall `asset_type` (using `ASSET_TYPE_DEFINITIONS`) based on the types of files assigned to that group name in the `individual_file_analysis`.\\n        *   Example: If files proposed as `AssetGroup1` include `MAP_COL`, `MAP_NRM`, `MAP_ROUGH`, classify `AssetGroup1` as `Surface`.\\n        *   Example: If files proposed as `AssetGroup2` include `MODEL` and texture maps, classify `AssetGroup2` as `Model`.\\n        *   Example: If `AssetGroup3` only has one file classified as `MAP_IMPERFECTION`, classify `AssetGroup3` as `UtilityMap`.\\n    *   Populate the `asset_group_classifications` dictionary, mapping each unique `proposed_asset_group_name` to its determined `asset_type`.\\n\\nInput File List:\\n\\ntext\\n{FILE_LIST}\\n\\n\\nOutput Format:\\n\\nYour response MUST be ONLY a single JSON object. You MAY include comments (using // or /* */) within the JSON structure for clarification if needed, but the core structure must be valid JSON.

+# Plan: Assessing Compilation of Asset Processor with PyInstaller and Cython
+
+## Objective
+
+To assess the feasibility and create a plan for compiling the Asset Processor project into standalone executables using PyInstaller, incorporating Cython for general speedup and source code obfuscation. A key requirement is to maintain user access to, and the ability to modify, configuration files (like `user_settings.json`, `asset_type_definitions.json`, etc.) and `Preset` files post-compilation.
+
+---
+
+## Phase 1: Initial Analysis & Information Gathering
+
+*   **Project Dependencies (from [`requirements.txt`](requirements.txt:1)):**
+    *   `opencv-python`
+    *   `numpy`
+    *   `openexr`
+    *   `PySide6`
+    *   `py7zr`
+    *   `rarfile`
+    *   `requests`
+    *   *Note: `PySide6`, `opencv-python`, and `openexr` may require special handling with PyInstaller (e.g., hidden imports, hooks).*
+*   **Configuration Loading (based on [`configuration.py`](configuration.py:1)):**
+    *   Configuration files (`app_settings.json`, `llm_settings.json`, `asset_type_definitions.json`, `file_type_definitions.json`, `user_settings.json`, `suppliers.json`) are loaded from a `config/` subdirectory relative to [`configuration.py`](configuration.py:1).
+    *   Preset files are loaded from a `Presets/` subdirectory relative to [`configuration.py`](configuration.py:1).
+    *   `BASE_DIR` is `Path(__file__).parent`, which will refer to the bundled location in a PyInstaller build.
+    *   [`user_settings.json`](configuration.py:16) is designed for overrides and is a candidate for external management.
+    *   Saving functions write back to these relative paths, which needs adaptation.
+*   **Potential Cython Candidates:**
+    *   Modules within the `processing/` directory.
+    *   Specifically: `processing/utils/image_processing_utils.py` and individual stage files in `processing/pipeline/stages/` (e.g., `alpha_extraction_to_mask.py`, `gloss_to_rough_conversion.py`, etc.).
+    *   Other modules (e.g., `processing/pipeline/orchestrator.py`) could be Cythonized primarily for obfuscation.
+*   **User-Accessible Files (Defaults):**
+    *   The `config/` directory (containing `app_settings.json`, `asset_type_definitions.json`, `file_type_definitions.json`, `llm_settings.json`, `suppliers.json`).
+    *   The `Presets/` directory and its contents.
+
+---
+
+## Phase 2: Strategy Development
+
+1.  **Cython Strategy:**
+    *   **Build Integration:** Utilize a `setup.py` script with `setuptools` and `Cython.Build.cythonize` to compile `.py` files into C extensions (`.pyd` on Windows, `.so` on Linux/macOS).
+    *   **Candidate Prioritization:** Focus on `processing/` modules for performance gains and obfuscation.
+    *   **Compatibility & Challenges:**
+        *   GUI modules (PySide6) are generally left as Python.
+        *   Ensure compatibility with OpenCV, NumPy, and OpenEXR.
+        *   Address potential issues with highly dynamic Python code.
+        *   Consider iterative conversion to `.pyx` files with C-style type annotations for maximum performance in identified hot spots.
+    *   **Obfuscation:** The primary goal for many modules might be obfuscation rather than pure speedup.
+
+2.  **PyInstaller Strategy:**
+    *   **Bundle Type:** One-directory bundle (`--onedir`) is recommended for easier debugging and data file management.
+    *   **Data Files (`.spec` file `datas` section):**
+        *   Bundle default `config/` directory (containing `app_settings.json`, `asset_type_definitions.json`, `file_type_definitions.json`, `llm_settings.json`, `suppliers.json`).
+        *   Bundle default `Presets/` directory.
+        *   Include any other necessary GUI assets (icons, etc.).
+        *   Consider bundling the `blender_addon/` if it's to be deployed with the app.
+    *   **Hidden Imports & Hooks (`.spec` file):**
+        *   Add explicit `hiddenimports` for `PySide6`, `opencv-python`, `openexr`, and any other problematic libraries.
+        *   Utilize or create PyInstaller hooks if necessary.
+    *   **Console Window:** Disable for GUI application (`console=False`).
+
+3.  **User-Accessible Files & First-Time Setup Strategy:**
+    *   **First-Run Detection:** Application checks for a marker file or stored configuration path.
+    *   **First-Time Setup UI (PySide6 Dialog):**
+        *   **Configuration Location Choice:**
+            *   Option A (Recommended): Store in user profile (e.g., `Documents/AssetProcessor` or `AppData/Roaming/AssetProcessor`).
+            *   Option B (Advanced): User chooses a custom folder.
+        *   The application copies default `config/` (excluding `app_settings.json` but including other definition files) and `Presets/` to the chosen location.
+        *   The chosen path is saved.
+        *   **Key Application Settings Configuration (saved to `user_settings.json` in user's chosen location):**
+            *   Default Library Output Path (`OUTPUT_BASE_DIR`).
+            *   Asset Structure (`OUTPUT_DIRECTORY_PATTERN`).
+            *   Image Output Formats (`OUTPUT_FORMAT_16BIT_PRIMARY`, `OUTPUT_FORMAT_16BIT_FALLBACK`, `OUTPUT_FORMAT_8BIT`).
+            *   JPG Threshold (`RESOLUTION_THRESHOLD_FOR_JPG`).
+            *   Blender Paths (`DEFAULT_NODEGROUP_BLEND_PATH`, `DEFAULT_MATERIALS_BLEND_PATH`, `BLENDER_EXECUTABLE_PATH`).
+    *   **Configuration Loading Logic Modification ([`configuration.py`](configuration.py:1)):**
+        *   `BASE_DIR` for user-modifiable files will point to the user-chosen location.
+        *   `app_settings.json` (master defaults) always loaded from the bundle.
+        *   `user_settings.json` loaded from the user-chosen location, containing overrides.
+        *   Other definition files and `Presets` loaded from the user-chosen location, with a fallback/re-copy mechanism from bundled defaults if missing.
+    *   **Saving Logic Modification ([`configuration.py`](configuration.py:1)):**
+        *   All configuration saving functions will write to the user-chosen configuration location. Bundled defaults remain read-only post-installation.
+
+---
+
+## Phase 3: Outline of Combined Build Process
+
+1.  **Environment Setup (Developer):** Install Python, Cython, PyInstaller, and project dependencies.
+2.  **Cythonization (`setup.py`):**
+    *   Create `setup.py` using `setuptools` and `Cython.Build.cythonize`.
+    *   List `.py` files/modules for compilation (e.g., `processing.utils.image_processing_utils`, `processing.pipeline.stages.*`).
+    *   Include `numpy.get_include()` if Cython files use NumPy C-API.
+    *   Run `python setup.py build_ext --inplace` to generate `.pyd`/`.so` files.
+3.  **PyInstaller Packaging (`.spec` file):**
+    *   Generate initial `AssetProcessor.spec` with `pyinstaller --name AssetProcessor main.py`.
+    *   Modify `.spec` file:
+        *   `datas`: Add default `config/` and `Presets/` directories, and other assets.
+        *   `hiddenimports`: List modules for `PySide6`, `opencv-python`, etc.
+        *   `excludes`: Optionally exclude original `.py` files for Cythonized modules.
+        *   Set `onedir = True`, `onefile = False`, `console = False`.
+    *   Run `pyinstaller AssetProcessor.spec` to create `dist/AssetProcessor`.
+4.  **Post-Build Steps (Optional):**
+    *   Clean up original `.py` files from `dist/` if obfuscation is paramount.
+    *   Archive `dist/AssetProcessor` for distribution (ZIP, installer).
+
+---
+
+## Phase 4: Distribution Structure
+
+**Inside `dist/AssetProcessor/` (Distribution Package):**
+
+*   `AssetProcessor.exe` (or platform equivalent)
+*   Core Python and library dependencies (DLLs/SOs)
+*   Cythonized modules (`.pyd`/`.so` files, e.g., `processing/utils/image_processing_utils.pyd`)
+*   Non-Cythonized Python modules (`.pyc` files)
+*   Bundled default `config/` directory (with `app_settings.json`, `asset_type_definitions.json`, etc.)
+*   Bundled default `Presets/` directory (with `_template.json`, `Dinesen.json`, etc.)
+*   Other GUI assets (icons, etc.)
+*   Potentially `blender_addon/` files if bundled.
+
+**User's Configuration Directory (e.g., `Documents/AssetProcessor/`, created on first run):**
+
+*   `user_settings.json` (user's choices for paths, formats, etc.)
+*   Copied `config/` directory (for user modification of `asset_type_definitions.json`, etc.)
+*   Copied `Presets/` directory (for user modification/additions)
+*   Marker file for first-time setup choice.
+
+---
+
+## Phase 5: Plan for Testing & Validation
+
+1.  **Core Functionality:** Test GUI operations, Directory Monitor, CLI (if applicable).
+2.  **Configuration System:**
+    *   Verify first-time setup UI, config location choice, copying of defaults.
+    *   Confirm loading from and saving to the user's chosen config location.
+    *   Test modification of user configs and application's reflection of changes.
+3.  **Dependency Checks:** Ensure bundled libraries (PySide6, OpenCV) function correctly.
+4.  **Performance (Cython):** Basic comparison of critical operations (Python vs. Cythonized).
+5.  **Obfuscation (Cython):** Verify absence of original `.py` files for Cythonized modules in distribution (if desired) and that `.pyd`/`.so` files are used.
+6.  **Cross-Platform Testing:** Repeat build and test process on all target OS.
+
+---
+
+## Phase 6: Documentation Outline
+
+1.  **Developer/Build Documentation:**
+    *   Build environment setup.
+    *   `setup.py` (Cython) and `pyinstaller` command usage.
+    *   Structure of `setup.py` and `.spec` file, key configurations.
+    *   Troubleshooting common build issues.
+2.  **User Documentation:**
+    *   First-time setup guide (config location, initial settings).
+    *   Managing user-specific configurations and presets (location, backup).
+    *   How to reset to default configurations.
+
+---
+
+## Phase 7: Risk Assessment & Mitigation (Brief)
+
+*   **Risk:** Cython compilation issues.
+    *   **Mitigation:** Incremental compilation, selective Cythonization.
+*   **Risk:** PyInstaller packaging complexities.
+    *   **Mitigation:** Thorough testing, community hooks, iterative `.spec` refinement.
+*   **Risk:** Logic errors in new configuration loading/saving.
+    *   **Mitigation:** Careful coding, detailed testing of config pathways.
+*   **Risk:** Cython performance not meeting expectations.
+    *   **Mitigation:** Profile Python code first; focus Cython on CPU-bound loops.
+*   **Risk:** Increased build complexity.
+    *   **Mitigation:** Automate build steps with scripts.

+# Plan for New Definitions Editor UI
+
+## 1. Overview
+
+This document outlines the plan to create a new, dedicated UI for managing "Asset Type Definitions", "File Type Definitions", and "Supplier Settings". This editor will provide a more structured and user-friendly way to manage these core application configurations, which are currently stored in separate JSON files.
+
+## 2. General Design Principles
+
+*   **Dedicated Dialog:** The editor will be a new `QDialog` (e.g., `DefinitionsEditorDialog`).
+*   **Access Point:** Launched from the `MainWindow` menu bar (e.g., under a "Definitions" menu or "Edit" -> "Edit Definitions...").
+*   **Tabbed Interface:** The dialog will use a `QTabWidget` to separate the management of different definition types.
+*   **List/Details View:** Each tab will generally follow a two-pane layout:
+    *   **Left Pane:** A `QListWidget` displaying the primary keys or names of the definitions (e.g., asset type names, file type IDs, supplier names). Includes "Add" and "Remove" buttons for managing these primary entries.
+    *   **Right Pane:** A details area (e.g., `QGroupBox` with a `QFormLayout`) that shows the specific settings for the item selected in the left-pane list.
+*   **Data Persistence:** The dialog will load from and save to the respective JSON configuration files:
+    *   Asset Types: `config/asset_type_definitions.json`
+    *   File Types: `config/file_type_definitions.json`
+    *   Supplier Settings: `config/suppliers.json` (This file will be refactored from a simple list to a dictionary of supplier objects).
+*   **User Experience:** Standard "Save" and "Cancel" buttons, with a check for unsaved changes.
+
+## 3. Tab-Specific Plans
+
+### 3.1. Asset Type Definitions Tab
+
+*   **Manages:** `config/asset_type_definitions.json`
+*   **UI Sketch:**
+    ```mermaid
+    graph LR
+        subgraph AssetTypeTab [Asset Type Definitions Tab]
+            direction LR
+            AssetList[QListWidget (Asset Type Keys e.g., "Surface")] --> AssetDetailsGroup{Details for Selected Asset Type};
+        end
+
+        subgraph AssetDetailsGroup
+            direction TB
+            Desc[Description: QTextEdit]
+            Color[Color: QPushButton ("Choose Color...") + Color Swatch Display]
+            Examples[Examples: QListWidget + Add/Remove Example Buttons]
+        end
+        AssetActions["Add Asset Type (Prompt for Name)\nRemove Selected Asset Type"] --> AssetList

+        end
+        SupplierActions["Add Supplier (Prompt for Name)\nRemove Selected Supplier"] --> SupplierList
+    ```
+*   **Details:**
+    *   **Left Pane:** `QListWidget` for supplier names. "Add Supplier" (prompts for new name) and "Remove Selected Supplier" buttons.
+    *   **Right Pane (Details):**
+        *   `normal_map_type`: `QComboBox` (options: "OpenGL", "DirectX"). Default for new suppliers: "OpenGL".
+        *   *(Space for future supplier-specific settings).*
+*   **Data Handling Note for `config/suppliers.json`:**
+    *   The editor will load from and save to `config/suppliers.json` using the new dictionary format (supplier name as key, object of settings as value).
+    *   Initial implementation might require `config/suppliers.json` to be manually updated to this new format if it currently exists as a simple list. Alternatively, the editor could attempt an automatic conversion on first load if the old list format is detected, or prompt the user. For the first pass, assuming the editor works with the new format is simpler.
+
+## 4. Implementation Steps (High-Level)
+
+1.  **(Potentially Manual First Step) Refactor `config/suppliers.json`:** If `config/suppliers.json` exists as a list, manually convert it to the new dictionary structure (e.g., `{"SupplierName": {"normal_map_type": "OpenGL"}}`) before starting UI development for this tab, or plan for the editor to handle this conversion.
+2.  **Create `DefinitionsEditorDialog` Class:** Inherit from `QDialog`.
+3.  **Implement UI Structure:** Main `QTabWidget`, and for each tab, the two-pane layout with `QListWidget`, `QGroupBox` for details, and relevant input widgets (`QLineEdit`, `QTextEdit`, `QComboBox`, `QCheckBox`, `QPushButton`).
+4.  **Implement Loading Logic:**
+    *   For each tab, read data from its corresponding JSON file.
+    *   Populate the left-pane `QListWidget` with the primary keys/names.
+    *   Store the full data structure internally (e.g., in dictionaries within the dialog instance).
+5.  **Implement Display Logic:**
+    *   When an item is selected in a `QListWidget`, populate the right-pane detail fields with the data for that item.
+6.  **Implement Editing Logic:**
+    *   Ensure that changes made in the detail fields (text edits, combobox selections, checkbox states, color choices, list example modifications) update the corresponding internal data structure for the currently selected item.
+7.  **Implement Add/Remove Functionality:**
+    *   For each definition type (Asset Type, File Type, Supplier), implement the "Add" and "Remove" buttons.
+        *   "Add": Prompt for a unique key/name, create a new default entry in the internal data, and add it to the `QListWidget`.
+        *   "Remove": Remove the selected item from the `QListWidget` and the internal data.
+    *   For "examples" lists within Asset and File types, implement their "Add Example" and "Remove Selected Example" buttons.
+8.  **Implement Saving Logic:**
+    *   When the main "Save" button is clicked:
+        *   Write the (potentially modified) Asset Type definitions data structure to `config/asset_type_definitions.json`.
+        *   Write File Type definitions to `config/file_type_definitions.json`.
+        *   Write Supplier settings (in the new dictionary format) to `config/suppliers.json`.
+    *   Consider creating new dedicated save functions in `configuration.py` for each of these files if they don't already exist or if existing ones are not suitable.
+9.  **Implement Unsaved Changes Check & Cancel Logic.**
+10. **Integrate Dialog Launch:** Add a menu action in `MainWindow.py` to open the `DefinitionsEditorDialog`.
+
+This plan provides a comprehensive approach to creating a dedicated editor for these crucial application definitions.

+# Refactoring Plan for Preferences Window (ConfigEditorDialog)
+
+## 1. Overview
+
+This document outlines the plan to refactor the preferences window (`gui/config_editor_dialog.py`). The primary goal is to address issues related to misaligned scope, poor user experience for certain data types, and incomplete interactivity. The refactoring will focus on making the `ConfigEditorDialog` a robust editor for settings in `config/app_settings.json` that are intended to be overridden by the user via `config/user_settings.json`.
+
+## 2. Assessment Summary
+
+*   **Misaligned Scope:** The dialog currently includes UI for "Asset Type Definitions" and "File Type Definitions". However, these are managed in separate dedicated JSON files ([`config/asset_type_definitions.json`](config/asset_type_definitions.json) and [`config/file_type_definitions.json`](config/file_type_definitions.json)) and are not saved by this dialog (which targets `config/user_settings.json`).
+*   **Poor UX for Data Types:**
+    *   Lists (e.g., `RESPECT_VARIANT_MAP_TYPES`) are edited as comma-separated strings.
+    *   Dictionary-like structures (e.g., `IMAGE_RESOLUTIONS`) are handled inconsistently (JSON defines as dict, UI attempts list-of-pairs).
+    *   Editing complex list-of-objects (e.g., `MAP_MERGE_RULES`) is functionally incomplete.
+*   **Incomplete Interactivity:** Many table-based editors lack "Add/Remove Row" functionality and proper cell delegates for intuitive editing.
+*   **LLM Settings:** Confirmed to be correctly managed by the separate `LLMEditorWidget` and `config/llm_settings.json`, so they are out of scope for this specific dialog refactor.

+```
+
+### Phase 1: Correct Scope & Critical UX/Data Fixes (in `gui/config_editor_dialog.py`)
+
+1.  **Remove Definitions Editing:**
+    *   **Action:** In `populate_definitions_tab`, remove the inner `QTabWidget` and the code that creates/populates the "Asset Types" and "File Types" tables.
+    *   The `DEFAULT_ASSET_CATEGORY` `QComboBox` (for the setting from `app_settings.json`) should remain. Its items should be populated using keys obtained from the `Configuration` class (which loads the actual `ASSET_TYPE_DEFINITIONS` from its dedicated file).
+    *   **Rationale:** Simplifies the dialog to settings managed via `user_settings.json`. Editing of the full definition files requires dedicated UI (see Future Enhancements note).
+
+2.  **Improve `RESPECT_VARIANT_MAP_TYPES` Editing:**
+    *   **Action:** In `populate_output_naming_tab`, replace the `QLineEdit` for `RESPECT_VARIANT_MAP_TYPES` with a `QListWidget` and "Add"/"Remove" buttons.
+    *   "Add" button: Use `QInputDialog.getItem` with items populated from `Configuration.get_file_type_keys()` (or similar method accessing loaded `FILE_TYPE_DEFINITIONS`) to allow users to select a valid file type key.
+    *   "Remove" button: Remove the selected item from the `QListWidget`.
+    *   Update `save_settings` to read the list of strings from this `QListWidget`.
+    *   Update `populate_widgets_from_settings` to populate this `QListWidget`.
+
+3.  **Fix `IMAGE_RESOLUTIONS` Handling:**
+    *   **Action:** In `populate_image_processing_tab`:
+        *   The `QTableWidget` for `IMAGE_RESOLUTIONS` should have two columns: "Name" (string, for the dictionary key) and "Resolution (px)" (integer, for the dictionary value).
+        *   In `populate_image_resolutions_table`, ensure it correctly populates from the dictionary structure in `self.settings['IMAGE_RESOLUTIONS']` (from `app_settings.json`).
+        *   In `save_settings`, ensure it correctly reads data from the table and reconstructs the `IMAGE_RESOLUTIONS` dictionary (e.g., `{"4K": 4096, "2K": 2048}`) when saving to `user_settings.json`.
+    *   ComboBoxes `CALCULATE_STATS_RESOLUTION` and `RESOLUTION_THRESHOLD_FOR_JPG` should be populated with the *keys* (names like "4K", "2K") from the `IMAGE_RESOLUTIONS` dictionary. `RESOLUTION_THRESHOLD_FOR_JPG` should also include "Never" and "Always" options. The `save_settings` method needs to correctly map these special ComboBox values back to appropriate storable values if necessary (e.g., sentinel numbers or specific strings if the backend configuration expects them for "Never"/"Always").
+
+4.  **Handle Simple Nested Settings (e.g., `general_settings`):**
+    *   **Action:** For `general_settings.invert_normal_map_green_channel_globally` (from `config/app_settings.json`):
+        *   Add a `QCheckBox` labeled "Invert Normal Map Green Channel Globally" to an appropriate tab (e.g., "Image Processing" or a "General" tab after layout review).
+        *   Update `populate_widgets_from_settings` to read `self.settings.get('general_settings', {}).get('invert_normal_map_green_channel_globally', False)`.
+        *   Update `save_settings` to write this value back to `target_file_content.setdefault('general_settings', {})['invert_normal_map_green_channel_globally'] = widget.isChecked()`.
+
+### Phase 2: Enhance `MAP_MERGE_RULES` Editor (in `gui/config_editor_dialog.py`)
+
+1.  **Rule Management:**
+    *   **Action:** In `populate_map_merging_tab`:
+        *   Connect the "Add Rule" button:
+            *   Create a default new rule dictionary (e.g., `{"output_map_type": "NEW_RULE", "inputs": {}, "defaults": {}, "output_bit_depth": "respect_inputs"}`).
+            *   Add it to the internal list of rules that will be saved (e.g., a copy of `self.settings['MAP_MERGE_RULES']` that gets modified).
+            *   Add a new `QListWidgetItem` for it and select it to display its details.
+        *   Connect the "Remove Rule" button:
+            *   Remove the selected rule from the internal list and the `QListWidget`.
+            *   Clear the details panel.
+
+2.  **Rule Details Panel Improvements (`display_merge_rule_details`):**
+    *   **`output_map_type`:** Change the `QLineEdit` to a `QComboBox`. Populate its items from `Configuration.get_file_type_keys()`.
+    *   **`inputs` Table:** The "Input Map Type" column cells should use a `QComboBox` delegate, populated with `Configuration.get_file_type_keys()` plus an empty/None option.
+    *   **`defaults` Table:** The "Default Value" column cells should use a `QDoubleSpinBox` delegate (e.g., range 0.0 to 1.0, or 0-255 if appropriate for specific channel types).
+    *   Ensure changes in these detail editors update the underlying rule data associated with the selected `QListWidgetItem` and the internal list of rules.
+
+### Phase 3: General UX & Table Interactivity (in `gui/config_editor_dialog.py`)
+
+1.  **Implement `IMAGE_RESOLUTIONS` Table Add/Remove Buttons:**
+    *   **Action:** In `populate_image_processing_tab`, connect the "Add Row" and "Remove Row" buttons for the `IMAGE_RESOLUTIONS` table.
+        *   "Add Row": Prompt for "Name" (string) and "Resolution (px)" (integer).
+        *   "Remove Row": Remove the selected row from the table and the underlying data.
+2.  **Implement Necessary Table Cell Delegates:**
+    *   **Action:** For the `IMAGE_RESOLUTIONS` table, the "Resolution (px)" column should use a `QSpinBox` delegate or a `QLineEdit` with integer validation to ensure correct data input.
+3.  **Review/Refine Tab Layout & Widget Grouping:**
+    *   **Action:** After the functional changes, review the overall layout of tabs and the grouping of settings within `gui/config_editor_dialog.py`.
+        *   Ensure settings from `config/app_settings.json` are logically placed and clearly labeled.
+        *   Verify widget labels are descriptive and tooltips are helpful where needed.
+        *   Confirm correct mapping between UI widgets and the keys in `app_settings.json` (e.g., `OUTPUT_FILENAME_PATTERN` vs. `TARGET_FILENAME_PATTERN`).
+
+## 4. Future Enhancements (Out of Scope for this Refactor)
+
+*   **Dedicated Editors for Definitions:** As per user feedback, if `ASSET_TYPE_DEFINITIONS` and `FILE_TYPE_DEFINITIONS` require UI-based editing, dedicated dialogs/widgets should be created. These would read from and save to their respective files ([`config/asset_type_definitions.json`](config/asset_type_definitions.json) and [`config/file_type_definitions.json`](config/file_type_definitions.json)) and could adopt a list/details UI similar to the `MAP_MERGE_RULES` editor.
+*   **Live Updates:** Consider mechanisms for applying some settings without requiring an application restart, if feasible for specific settings.
+
+This plan aims to create a more focused, usable, and correct preferences window.

+# Project Brief: Asset Processor Tool
+
+## 1. Main Goal & Purpose
+
+The primary goal of the Asset Processor Tool is to provide **CG artists and 3D content teams with a friendly, fast, and flexible interface to process and organize 3D asset source files into a standardized library format.** It automates repetitive and complex tasks involved in preparing assets from various suppliers for use in production pipelines.
+
+## 2. Key Features & Components
+
+*   **Automated Asset Processing:** Ingests 3D asset source files (texture sets, models, etc.) from `.zip`, `.rar`, `.7z` archives, or folders.
+*   **Preset-Driven Workflow:** Utilizes configurable JSON presets to interpret different asset sources (e.g., from various online vendors or internal standards), defining rules for file classification and processing.
+*   **Comprehensive File Operations:**
+    *   **Classification:** Automatically identifies map types (Color, Normal, Roughness, etc.), models, and other file categories based on preset rules.
+    *   **Image Processing:** Performs tasks like image resizing (to standard resolutions like 1K, 2K, 4K, avoiding upscaling), glossiness-to-roughness conversion, normal map green channel inversion (OpenGL/DirectX handling), alpha channel extraction, bit-depth adjustments, and low-resolution fallback generation for small source images.
+    *   **Channel Merging:** Combines channels from different source maps into packed textures (e.g., Normal + Roughness + Metallic into a single NRMRGH map).
+*   **Metadata Generation:** Creates a detailed `metadata.json` file for each processed asset, containing information about maps, categories, processing settings, and more, for downstream tool integration.
+*   **Flexible Output Organization:** Generates a clean, structured output directory based on user-configurable naming patterns and tokens.
+*   **Multiple User Interfaces:**
+    *   **Graphical User Interface (GUI):** The primary interface, designed to be user-friendly, offering drag-and-drop functionality, an integrated preset editor, a live preview table for rule validation and overrides, and clear processing controls.
+    *   **Directory Monitor:** An automated script that watches a specified folder for new asset archives and processes them based on preset names embedded in the archive filename.
+    *   **Command-Line Interface (CLI):** Intended for batch processing and scripting (currently with limited core functionality).
+*   **Optional Blender Integration:** Can automatically run Blender scripts post-processing to create PBR node groups and materials in specified `.blend` files, linking to the newly processed textures.
+*   **Hierarchical Rule System:** Allows for dynamic, granular overrides of preset configurations at the source, asset, or individual file level via the GUI.
+*   **Experimental LLM Prediction:** Includes an option to use a Large Language Model for file interpretation and rule prediction.
+
+## 3. Target Audience
+
+*   **CG Artists:** Individual artists looking for an efficient way to manage and prepare their personal or downloaded asset libraries.
+*   **3D Content Creation Teams:** Studios or groups needing a standardized pipeline for processing and organizing assets from multiple sources.
+*   **Technical Artists/Pipeline Developers:** Who may extend or integrate the tool into broader production workflows.
+
+## 4. Overall Architectural Style & Key Technologies
+
+*   **Core Language:** Python
+*   **GUI Framework:** PySide6
+*   **Configuration:** Primarily JSON-based (application settings, user overrides, type definitions, supplier settings, presets, LLM settings).
+*   **Processing Architecture:** A modular, staged processing pipeline orchestrated by a central engine. Each stage performs a discrete task on an `AssetProcessingContext` object.
+*   **Key Libraries:** OpenCV (image processing), NumPy (numerical operations), py7zr/rarfile (archive handling), watchdog (directory monitoring).
+*   **Design Principles:** Modularity, configurability, and user-friendliness (especially for the GUI).
+
+## 5. Foundational Information
+
+*   The tool aims to significantly reduce manual effort and ensure consistency in asset preparation.
+*   It is designed to be adaptable to various asset sources and pipeline requirements through its extensive configuration options and preset system.
+*   The output `metadata.json` is key for enabling further automation and integration with other tools or digital content creation (DCC) applications.

Your task is to analyze a list of file paths, understand their relationships based on naming and directory structure, and output a structured JSON object that classifies each file individually and then classifies the logical asset groups they belong to.\\n\\nDefinitions:\\n\\nAsset Types: These define the overall category of a logical asset group. Use one of the following keys when classifying asset groups. Each definition is provided as a formatted string (e.g., 'Surface = A single PBR material set..., examples: WoodFloor01, MetalPlate05'):\\n{ASSET_TYPE_DEFINITIONS}\\n\\n\\nFile Types: These define the specific purpose of each individual file. Use one of the following keys when classifying individual files. Each definition is provided as a formatted string (e.g., 'MAP_COL = Color/Albedo Map, examples: _col., _basecolor.'):\\n{FILE_TYPE_DEFINITIONS}\\n\\n\\nCore Task & Logic:\\n\\n1.  **Individual File Analysis:**\\n    *   Examine each `relative_file_path` in the input `FILE_LIST`.\\n    *   For EACH file, determine its most likely `classified_file_type` using the `FILE_TYPE_DEFINITIONS`. Pay attention to filename suffixes, keywords, and extensions. Use `FILE_IGNORE` for files like `Thumbs.db` or `.DS_Store`. Use `EXTRA` for previews, metadata, or unidentifiable maps.\\n    *   For EACH file, propose a logical `proposed_asset_group_name` (string). This name should represent the asset the file likely belongs to, based on common base names (e.g., `WoodFloor01` from `WoodFloor01_col.png`, `WoodFloor01_nrm.png`) or directory structure (e.g., `SciFi_Drone` for files within that folder).\\n        *   Files that seem to be standalone utility maps (like `scratches.png`, `FlowMap.tif`) should get a unique group name derived from their filename (e.g., `Scratches`, `FlowMap`).\\n        *   If a file doesn't seem to belong to any logical group (e.g., a stray readme file in the root), you can propose `null` or a generic name like `Miscellaneous`.\\n        *   Be consistent with the proposed names for files belonging to the same logical asset.\\n    *   Populate the `individual_file_analysis` array with one object for *every* file in the input list, containing `relative_file_path`, `classified_file_type`, and `proposed_asset_group_name`.\\n\\n2.  **Asset Group Classification:**\\n    *   Collect all unique, non-null `proposed_asset_group_name` values generated in the previous step.\\n    *   For EACH unique group name, determine the overall `asset_type` (using `ASSET_TYPE_DEFINITIONS`) based on the types of files assigned to that group name in the `individual_file_analysis`.\\n        *   Example: If files proposed as `AssetGroup1` include `MAP_COL`, `MAP_NRM`, `MAP_ROUGH`, classify `AssetGroup1` as `Surface`.\\n        *   Example: If files proposed as `AssetGroup2` include `MODEL` and texture maps, classify `AssetGroup2` as `Model`.\\n        *   Example: If `AssetGroup3` only has one file classified as `MAP_IMPERFECTION`, classify `AssetGroup3` as `UtilityMap`.\\n    *   Populate the `asset_group_classifications` dictionary, mapping each unique `proposed_asset_group_name` to its determined `asset_type`.\\n\\nInput File List:\\n\\ntext\\n{FILE_LIST}\\n\\n\\nOutput Format:\\n\\nYour response MUST be ONLY a single JSON object. You MAY include comments (using // or /* */) within the JSON structure for clarification if needed, but the core structure must be valid JSON. Do NOT include any text, explanations, or introductory phrases before or after the JSON object itself. Ensure all strings are correctly quoted and escaped.\\n\\nCRITICAL: The output JSON structure must strictly adhere to the following format:\\n\\n```json\\n{{\\n  \"individual_file_analysis\": [\\n    {{\\n      // Optional comment about this file\\n      \"relative_file_path\": \"string\", // Exact relative path from the input list\\n      \"classified_file_type\": \"string\", // Key from FILE_TYPE_DEFINITIONS\\n      \"proposed_asset_group_name\": \"string_or_null\" // Your suggested group name for this file\\n    }}\\n    // ... one object for EVERY file in the input list\\n  ],\\n  \"asset_group_classifications\": {{\\n    // Dictionary mapping unique proposed group names to asset types\\n    \"ProposedGroupName1\": \"string\", // Key: proposed_asset_group_name, Value: Key from ASSET_TYPE_DEFINITIONS\\n    \"ProposedGroupName2\": \"string\"\\n    // ... one entry for each unique, non-null proposed_asset_group_name\\n  }}\\n}}\\n```\\n\\nExamples:\\n\\nHere are examples of input file lists and the desired JSON output, illustrating the two-part structure:\\n\\njson\\n[\\n {EXAMPLE_INPUT_OUTPUT_PAIRS}\\n]\\n\\n\\nNow, process the provided FILE_LIST and generate ONLY the JSON output according to these instructions. Remember to include an entry in `individual_file_analysis` for every single input file path."
