🔌 Karcytics SDK

The Software Development Kit (SDK) and Command-Line Interface (CLI) for building, validating, and signing plugins for the Karcytics desktop scientific suite.

🚀 Key Features

• Decoupled Architecture: Build and test PyQt6-based scientific plugins independently of the main desktop app.
• Fail-Safe Dynamic Theme Fallbacks: Visual components automatically load custom HSL-tailored colors when running standalone inside CI/CD test gates or external visualizers.
• Merkle-Tree Cryptographic Integrity: Built-in Ed25519 signing and verification tools to secure user environments against remote execution and tampering.
• PyPI-Ready Packaging: Complete declarative pyproject.toml config, built to publish natively under the karcytics-sdk package.

🛠️ Installation

Install the SDK directly into your plugin's virtual environment:

pip install karcytics-sdk

(Or during development, install in editable mode):

git clone https://github.com/KalaimaranB/Karcytics-SDK.git
cd Karcytics-SDK
pip install -e .

📦 Creating a Custom Karcytics Plugin

To build a valid plugin, implement the KarcyticsPlugin interface and declare your entrypoints.

1. manifest.json

Every plugin must include a manifest file in its root directory:

{
  "id": "my_custom_plugin",
  "name": "My Custom Plugin",
  "version": "1.0.0",
  "author": "Dr. Kalaimaran",
  "description": "High-performance scientific analysis plugin.",
  "category": "analysis",
  "min_core_version": "1.0.0",
  "entrypoint": "plugin:MyPluginClass"
}

2. plugin.py

from PyQt6.QtWidgets import QWidget, QVBoxLayout, QLabel
from karcytics_sdk.core.interfaces import KarcyticsPlugin
from karcytics_sdk.ui import PrimaryButton


class MyPluginClass(KarcyticsPlugin):
    """A professional-grade Karcytics plugin."""

    def initialize(self) -> None:
        self.logger.info("Initializing custom plugin...")

    def create_panel(self, parent=None) -> QWidget:
        panel = QWidget(parent)
        layout = QVBoxLayout(panel)

        title = QLabel("Welcome to Custom Analysis Panel")
        btn = PrimaryButton("Execute Step")

        layout.addWidget(title)
        layout.addWidget(btn)
        return panel

🛡️ Cryptographic Trust Architecture

Karcytics implements a professional-grade Chain of Trust to protect laboratory environments:

[ Root Authority ] (Hardcoded Core Key)
       │
       ▼ (signs)
[ Developer Key ] (Dev Certificate)
       │
       ▼ (signs)
[ Plugin Manifest ] (Ed25519 Signature + Merkle-Tree Hashes)

1. Generate Your Cryptographic Identity

karcytics-sdk setup-identity

• Local Private Key: ~/.karcytics/dev_private_key.pem
• Developer Certificate: ~/.karcytics/dev_cert.bin

2. Sign Your Plugin payload

Calculates Merkle-hashes for all your files recursively, excludes development directories automatically, updates manifest.json, and writes signature.bin:

karcytics-sdk sign <path/to/plugin>

3. Modularity Compliance Check

Verify your plugin matches QA and security standards:

karcytics-sdk evaluate <path/to/plugin>

📘 Standalone Preview Support

Since the SDK decouples all theme components from the desktop core using robust try-except fallbacks, you can instantiate and preview components standalone in development:

import sys
from PyQt6.QtWidgets import QApplication
from karcytics_sdk.ui import PrimaryButton, WizardPanel

app = QApplication(sys.argv)
widget = WizardPanel()  # Renders beautifully even without the main app!
widget.show()
sys.exit(app.exec())
