>Does the Knowledge Graph have to index all those values for the mapping to work?
There are both options. You can index them as entities [1] within Veezoo and keep the mapping automatically synchronized with the database. Or decide to not index them, which will make Veezoo e.g. attempt answering the question using string search in SQL.
>On the adaptive plans, Is that execution logic handled entirely by your deterministic compiler, or does it loop back to the LLM to interpret the intermediate results?
The plan is done entirely by the LLM. The VQL steps (i.e. fetching answers from the database) within the plan is where the compiler kicks in.
