Thanks for the review. I merged current Updated commit:
As with the existing cloud LLM presets, API Route uses the shared transport after the user explicitly configures and selects it with their own key. The PR remains focused on this optional preset. |

Sanction API Route before adding the provider.
API Route adds an outbound destination that is not in the sanctioned list. The local-first rule permits only listed calls and requires owner approval to add another. Add API Route to the list after owner approval, or remove the provider.
Suggested fix
- The Lemon Squeezy Pro licence check, only after the user enters a key
(`electron/src/main/pro-license.ts`).
+ - API Route LLM requests, only after owner approval and explicit provider
+ selection with a configured API key (`backend/services/llm_providers.py`).🤖 Prompt for AI Agents

Hi @debpalash, could you please confirm whether you approve API Route as an optional outbound LLM destination under the local-first contribution policy? CodeRabbit raised this explicitly in the review thread. I checked the current contribution guide and could not find an approval for this preset. The default destination is With your approval, I can add the narrowly scoped entry to the sanctioned-destination list. Please let me know if you require any additional conditions for the preset. The CI and Security workflows also await maintainer approval; could you approve those when reviewing this request? Thank you. |

Users must configure a key and select the provider before making cloud requests. The author reports that focused tests passed; the engine-inventory test was deselected because Torch was unavailable.
