Change the structured index schema from one sentence of plain language. Example requests: "also track the author so users can find other books by them", "I want to filter by illustrator", "drop the cover link". The model may only emit add/modify/remove/refused — it cannot rewrite the table, so it has no way to damage columns the user did not mention. **Data that is not in the documents comes back in `refused`, not as a new column.** Asked for a publication year that the corpus does not carry, it says so instead of inventing an empty column. Pass that refusal on to the user verbatim. Call with `apply=false` first and show the user what would change; batch several edits and apply once. Applying marks the index for rebuild — it does **not** re-embed anything, so it is cheap.
