📐 Architecture & Security Notes

Opti-Link Instant Messenger (v0.9.0.0) is primarily a client-side application designed to interact with locally-hosted AI models via LM Studio.

Local-First Operation: The application prioritizes local execution and interaction. LM Studio connections are typically to localhost.
PowerShell Scripting: The application is written entirely in PowerShell, leveraging its capabilities for GUI development and system interaction.
Configuration Storage: All application settings are stored locally in JSON files within the OptiLink_Config directory, adjacent to the script. No external cloud services are used for configuration.
No Telemetry: The application does not collect or transmit any user data or telemetry.
