What it expects
This adapter is trained for retrieval-augmented use, and it will not behave
correctly without the retrieved passages: the training examples always contain
six passages in the system prompt, so the adapter must be prompted the same
way. The system prompt has the form
Sei un assistente di finanza personale. L'utente ha conoscenze di finanza intermedie.
RULES: ...

followed by the user's question. The persona sentence states the reader's
level, and it is what selects the register: the adapter was trained on three
of them (basic, intermediate, advanced), so the same question returns an
answer written at the requested level.
Training
LoRA rank 8, alpha 16, dropout 0.05, on the attention and feed-forward
projections, loss on answer tokens only. 4 epochs, learning rate 5e-5,
