# Third-party notices

This plugin is independently implemented. It imports the official ACP SDK
and DeepSeek Harness packages; their licenses remain with their distributions.
No Google executable, credential file, or third-party implementation is copied
into this repository or package.

ZIP extraction uses [yauzl](https://github.com/thejoshwolfe/yauzl) (MIT), imported
as a package dependency. Official Google archives are downloaded directly to a
local cache at runtime; they are not redistributed by this repository.
