Remove it
The provider setup created is Bonsai itself. Its card has no rename and its editor offers only Remove Bonsai; Remove on the Synoec tab’s card does the same. Removal deletes the provider first, so a Profile that still uses it stops removal before anything else changes. It then quits the service, turns off start with Synoec, and deletes the runtime, model, image generation, downloads, log, configuration and the saved record.
The record lives with the files, not with the app’s data, so resetting or
reinstalling the app keeps Bonsai; the installer’s Install fresh mode
keeps the runtime and model too and deletes the rest. On the next start
Synoec finds the files, and setup becomes a verification instead of a
download. A record from an earlier version (local-ai.json in the app’s data)
is read once for its Connection and start-with-Synoec setting, then removed;
its runtime and models under local-runtimes and local-models are no
longer used and can be deleted.
