Start from the decision a reviewer must make
Evidence design should begin with the questions an operator, risk owner or auditor will ask. Which version ran? Who approved it? What inputs were used? Which actions were automated? Where did a person intervene?
Capturing every technical event is not the same as producing usable evidence. The receipt should make the control story legible.
The minimum useful receipt
A controlled agentic workflow should produce a structured record with at least the following fields.
- Workflow, model, policy and tool versions
- Local approvers and release time
- Inputs by reference, not unnecessary duplication
- Automated actions and human checkpoints
- Exceptions, overrides and outcome measures
Evidence should improve operations
Receipts are not only for retrospective assurance. Aggregated exception patterns, rework and approval delays show where the workflow itself should change. Evidence becomes part of the operating feedback loop.
This note is general information, not legal, regulatory or investment advice. Control design must reflect each company’s actual obligations and operating context.
