Notes brèves sur ce qu'un assistant IA peut et ne peut pas faire en mer.
Notes depuis la construction de Nausika. Où le modèle aide, où il hallucine et où les bonnes données comblent l'écart.

What Nausika is not
A short note on the limits. Nausika is a connector for an assistant. It is not a chartplotter, not your instruments, not the watch on deck.
The assistant knows you. It doesn't know the water.
Your AI knows your preferences. It can't compute a bearing. That's a division of labor, not a bug.
Where data lives
On choosing real, attributable sources as the things behind the connector. Notes on why the protocol matters more than the model.
The line that crosses the peninsula
An assistant draws a route. The route runs across land. Everything else it says still sounds correct. That is the whole problem.
