A trace here need not be a data file. A measurement problem, a record mismatch, a model that disagrees with the site, a sensor whose measurand is unclear, a claim that may exceed its evidence: each is a trace of the fracture this work is about.
- What is the physical process?
- What records do you have?
- What claim is being made?
- Where does the relationship stop being clear?
- What consequence depends on getting it right?
Do not send proprietary data with your first message. Start with the question; authorisation comes later.
What happens next: we reply with what the records you describe can and cannot support, and what evidence would make the question decidable. Sometimes the honest answer is that it cannot be established from what exists — that answer is part of the work, not a failure of it.
