Looks good; there are just a few minor comments left. I will remove the draft status.

This is looking great! I've only left some smaller suggestions regarding documentation and naming things.

Me and @gligneul discussed and decided it was best to remove the first parameter from the GetInputs function, as this a debug tool that doesn't need pagination. Now, it returns all inputs ordered by index.

The merge-base changed after approval.

Could you add an entry in the CHANGELOG?
