Mr. Pipe

A business changes CRM, adds a project tracker, or moves reporting into a spreadsheet, and someone has to carry the records across. That work is usually done by hand, or by a script written once and never read again.

Field names do not match. Picklists do not match. A phone number is formatted six ways, a required field on the target has no source at all, and a currency lands in a text box. None of that is visible while it is happening. It becomes visible afterwards, in the target system, at scale.

Mr. Pipe makes the write the last step instead of the first. It reads both schemas, shows every field decision with a confidence on it, runs the whole thing against real records without writing anything, and only then asks.

Field mapping is a good use of a model. It is pattern matching across two vocabularies, and a model does it faster and more completely than a person reading two schemas side by side. What a model should not do is act on its own output.

So the confidence score is shown rather than used as a threshold to auto-apply. Low confidence is not hidden, it is sorted to the front. The reasoning is written out per row, so a decision can be disagreed with instead of merely accepted. Approval is one deliberate action over a reviewed set, not a click that happens per row while attention drifts.

And the last gate is mechanical rather than a matter of care: the dry run cannot write. It produces the preview and stops. The interface says so on the job itself, while the job is running.

Nothing written, preview only
