# Aether Project Architecture

This document outlines the overall architecture and key technologies used in the Aether SvelteKit frontend project.

## 1. Project Overview
The Aether project is a Svelte and SvelteKit based application, utilizing Tailwind CSS and Skeleton for styling and UI elements. It serves as the frontend UI/UX for the Aether system, which interacts with a Python FastAPI backend.

## 2. Core Technologies
* **Frontend Framework:** Svelte 5 and SvelteKit v2
  * **Routing:** SvelteKit's file-system based routing.
* **Styling:** Tailwind CSS 3.x (with plans to upgrade to 4.x when ShadCN is ready)
*   **UI Component Libraries:**
    *   Skeleton (Design System, Tailwind Components, Functional Components - with plans to upgrade to v3)
    *   Flowbite (Tailwind Components)
    *   **Note:** ShadCN is currently used but is planned for removal.
*   **Text/Code Editors:**
    *   CodeMirror 6.x (primary text and code editor, planned for rich text editing)
    *   Edra (TipTap based Rich Text Editor)
    *   **Note:** ShadEditor TipTap is present but marked for removal, with CodeMirror being the preferred solution for all text editing needs.
* **Icons:** Lucide Icons (SVG Icons)
* **Markdown Parsing:** `marked` library
* **State Management:** Svelte stores, potentially with `liveQuery` from Dexie for reactive IndexedDB interactions.

## 3. Module Structure
The Aether project is organized into several modules, categorized as Core, Extended, and Custom.

### 3.1. Official Modules
#### Core Modules
These are foundational modules essential for the application's basic functionality.
* **Accounts:** Minimal implementation.
* **Files:** Manages hosted files.
* **People:** Minimal implementation for person records.
* **Sites:** Minimal implementation for site configurations.
* **Users:** Minimal implementation for user management.

#### Extended Modules
These modules provide additional features and functionalities.
* **Archives:** Minimal implementation.
* **Events:** Includes features for Badges and Presentation Management.
* **Posts:** Minimal implementation.
* **Journals:** Manages journal entries.

#### Custom Modules
These modules are tailored for specific client needs.
* **IDAA:** Includes Archives, Bulletin Board (BB), and Recovery Meetings functionalities.

## 4. Data Storage Mechanisms
### 4.1. Local Storage
Used for client-side persistence of various application states and configurations.
* `api`: API-related settings.
* `app`: Global application settings.
* `core`: Settings and data specific to core modules.
* `<module>`: Settings and data specific to extended modules.
* `<custom>`: Settings and data specific to custom modules.

### 4.2. IndexedDB (Dexie.js)
Used for more structured client-side data storage, often for caching and offline capabilities.
* `ae_core_db`: Core database instance.
* `<module>`: Module-specific database instances.
* `<custom>`: Custom module-specific database instances (none currently defined).

## 5. Data Sorting
Standardized sorting orders are applied across various data lists.
* **Default/General:** `group > priority > sort > updated_on/created_on`
* **Specific (e.g., Events):** `type > start_date/time > code or name`

## 6. Object Properties and Fields
A set of standardized field names and types are used across Aether objects.

### 6.1. Core Standard Fields
These fields are expected to be present in most Aether objects.
* `id`: Primary key for an object (internal use, often a UUID).
* `id_random`: Randomly generated ID for an object (often used for external exposure or URL parameters).
* `<object_type>_id_random`: Specific random ID for an object (e.g., `person_id_random`).
* `code`: Short, unique identifier.
* `name`: Display name.
* `enable`: Boolean for active/inactive status.
* `hide`: Boolean for visibility.
* `priority`: Numeric value for ordering.
* `sort`: Numeric value for ordering.
* `group`: Categorization string.
* `notes`: General notes/comments.
* `created_on`: Timestamp of creation.
* `updated_on`: Timestamp of last update.

### 6.2. Special Use Fields
Fields with specific purposes or conditional usage.
* `for_type`: Indicates the type of object this object is linked to.
* `for_id`: The ID of the object this object is linked to.
* `archive_on`: Timestamp for archiving.
* `passcode`: Password or access code.
* `external_id`: ID from an external system.

### 6.3. Configuration and JSON Fields
Fields designed to store JSON data.
* `cfg_json`: Configuration data in JSON format.
* `data_json`: General data in JSON format.
* `linked_li_json`: List of linked items in JSON format.

### 6.4. Special Generated Fields (Client-side)
Fields generated on the client-side, primarily for sorting or UI logic.
* `tmp_sort_1`
* `tmp_sort_2`
* `tmp_sort_3`

### 6.5. Future Standard Fields
A list of potential future standard fields, often prefixed with `obj_`. These are currently conceptual and not yet fully integrated.
* `obj_id`, `obj_ext_uid`, `obj_ext_id`, `obj_import_id`, `obj_code`, `obj_account_id`, `obj_passcode`, `obj_type`, `obj_type_ver_id`, `obj_name`, `obj_summary`, `obj_outline`, `obj_description`, `obj_enable`, `obj_enable_on`, `obj_archive_on`, `obj_hide`, `obj_priority`, `obj_sort`, `obj_group`, `obj_cfg_json`, `obj_notes`, `obj_created_on`, `obj_updated_on`.

## 7. IndexedDB LiveQuery Usage
* `lq__xyz_obj`: Used for general read-only access to liveQuery results.
* `lqw__xyz_obj`: Used for forms and binding values, representing a writable snapshot of liveQuery results.
  * **Note:** Care must be taken when binding to `lqw__xyz_obj` to manage updates and potential conflicts with the underlying liveQuery.
