All notable changes to this project are documented here. The format follows Keep a Changelog, and versions follow Semantic Versioning.

The subscription hub now covers three browser-authorized subscriptions: OpenAI / ChatGPT (hardened end to end, image generation), xAI / Grok (catalog-driven wire protocol and per-model reasoning levels), and GitHub Copilot (device-code sign-in with the account's live model catalog). Model lists and reasoning levels stay fully dynamic from each account's catalog.
