unsupported tab for custom model: %v

Error message

unsupported tab for custom model: %v

What it means

Guard in the provider TUI's model-add flow: the save routine was invoked from a tab whose context is not a recognized custom-model context. The tab value (e.g. official provider list, an edit form, search) cannot have models added to it, so the function refuses rather than writing a model to the wrong provider entry.

Solutions

1. Report this as a bug: this message indicates an internal state error where the add-model flow was invoked from an unexpected tab
2. Avoid manually constructing model-add requests for official providers through this path; user models for official providers belong in existingCfg.Providers only
