Every number in an answer is computed by the platform from your reconciled ledger, never typed by the model. One click opens its evidence: the formula, the lookups behind it and the data read from your systems, with the rows of every step as Excel.
Every number in the text carries a marker. Click one and it leads the panel beside the conversation, with what it means and every step that produced it.
Numbers in the answer are computed by the platform from your ledger and marked F1, F2 and so on. If the assistant writes a number that no computation backs, it is removed from the text and marked as unverified.
The number leads the panel at full size, with its exact value, its unit and one sentence on what it means. Under it, every step that produced it, the last one open.
Each step states what it read, what it ran and what it produced: the formula over two numbers, the lookup that summed each half-year, the data read beneath them. A number a step reads opens its own evidence.
The data read is stated the way a spreadsheet states its filters: what was read, how it was grouped, the period, the comparison and the filters, then the system it came from and when it was last synced. The rows of every step download as Excel, the same file each time.
A number in an answer is the last link of a chain the platform keeps: the data read from your connected systems, each calculation on the way, and the value that reached the answer.
What the platform keeps, what it refuses to pass off as fact, and where every number comes from.
An assistant can write a plausible number. A finance answer needs the calculation behind it and the system it came from, kept where anyone can open them.
A walkthrough on your own systems: ask, click a number and follow it to its source.
