 This module handles the parsing, management, and evaluation of PrusaSlicer configuration profiles (`.ini` files). It supports profile inheritance, compatibility evaluation using PrusaSlicer's expression language, and generating merged configurations for slicing.
 
+## Project Structure
+
+- **`__init__.py`**: Exports the primary API (`LocalCache`, `Profile`, `ConfigWriter`).
+- **`cache.py`**: Contains the `LocalCache` class for managing profile loading and metadata.
+- **`models.py`**: Defines core data models like `Profile` (as a dataclass) and `ConfigWriter`.
+- **`parser.py`**: Implements a recursive descent parser for PrusaSlicer's expression language.
+- **`fields.py`**: Robustly loads and searches PrusaSlicer setting metadata (JSON/CSV).
+- **`utils.py`**: Contains canonical implementations of INI parsing and configuration merging (`generate_conf`).
+
 ## Core Components
 
-### 1. `profiles.py`
+### 1. `LocalCache` (`cache.py`)
-- **`Profile` Class**: Represents a single PrusaSlicer profile (Printer, Filament, or Print).
+- Manages a collection of profiles loaded from disk.
+- Scans directories for `.ini` files and tracks changes using file metadata.
+- Categorizes profiles into `printer`, `print`, and `filament`.
+- `evaluate_compatibility`: Checks which filament and print profiles are compatible with specific printer profiles.
+- `generate_conf_writer`: Creates a `ConfigWriter` by merging a printer, print, and one or more filament profiles.
+
+### 2. `Profile` (`models.py`)
+- Represents a single PrusaSlicer profile (Printer, Filament, or Print).
 - Stores configuration as a dictionary (`conf_dict`).
 - Handles inheritance logic via `generate_inherited_confs`.
 - Supports compatibility checks via `evaluate_compatibility`.
-- **`generate_conf` Function**: Recursively merges inherited profiles into a single configuration dictionary.
 
-### 2. `profile_cache.py`
+### 3. `ConfigWriter` (`models.py`)
-- **`LocalCache` Class**: Manages a collection of profiles loaded from disk.
+- Helper to write merged configurations to a file (e.g., for passing to a slicer or embedding in a 3MF).
-  - Scans directories for `.ini` files and tracks changes using file metadata.
+- Includes checksum generation for configuration integrity.
-  - Categorizes profiles into `printers`, `print`, and `filament`.
-  - `evaluate_compatibility`: Checks which filament and print profiles are compatible with specific printer profiles.
-  - `generate_conf_writer`: Creates a `ConfigWriter` by merging a printer, print, and one or more filament profiles (multi-extruder support).
-- **`ConfigWriter` Class**: Helper to write the merged configuration to a file (e.g., for passing to a slicer or embedding in a 3MF).
-- **Utility Functions**: `ini_to_dict` and `ini_content_to_dict` use `ConfigParser` to parse PrusaSlicer's INI format.
 
-### 3. `expression_parser.py`
+### 4. `Parser` (`parser.py`)
-- Implements a recursive descent parser for PrusaSlicer's expression language (used in `compatible_printers_condition` and similar fields).
+- Tokenizes and parses expression strings into an AST that can be evaluated against a configuration dictionary.
-- **AST Nodes**: `ExprNode`, `LiteralNode`, `VarNode`, `IndexNode`, `UnaryOpNode`, `BinaryOpNode`.
+- Supports variables, indexing, logical operators, and regex matching.
-- **`Parser` Class**: Tokenizes and parses expression strings into an AST that can be evaluated against a configuration dictionary.
 
-### 4. `prusaslicer_fields.py`
+### 5. `fields.py`
 - Loads metadata about PrusaSlicer configuration fields from `prusaslicer_fields.json` and `prusaslicer_modifier_fields.csv`.
-- Provides `search_in_db` and `search_in_mod_db` for looking up field definitions, types, and labels.
+- Uses robust path resolution relative to the module's directory.
-
-## Data Files
-- `prusaslicer_fields.json`: Exhaustive database of PrusaSlicer settings, including types, default values, and labels.
-- `prusaslicer_modifier_fields.csv`: List of fields that are valid as modifiers.
 
 ## Typical Workflow
 1. Initialize `LocalCache`.
