Signed reply
A signed reply is an assistant's answer that marks which of its sentences rest on a tool's result, so that the person can tell the record's facts from the assistant's own words. IZeat's own reply carries "IZeat ·" in front of it: the receipt states what was recorded, what the day now totals and what is left against the target. Keeping that prefix when it relays the receipt is asked of the assistant, not enforced on it, so a reply that lost it can still be IZeat's.
A refusal is a receipt signed the same way and ends with what happened, "Nothing was recorded" or "Nothing was changed", so a customer never wonders whether a failed write left something behind. In an assistant that shows interactive reports, a request for a balance or a chart draws the day and the text stays to the signed line and a sentence or two. Sentences the assistant relays verbatim are written once in IZeat's code and never paraphrased.
The signature is how trust survives the mixing of two voices in one chat: the assistant's, which may advise, joke or translate, and IZeat's, which only records. It is a convention rather than a proof, so a missing prefix settles nothing either way. That line is what lets the product never prescribe while the assistant remains free to.
Put it into practice: How a reply is signed.
