You approve the actual change — not a sentence about it
Most systems that "ask for approval" show you a sentence about what will happen and a button. You approve the sentence, not the act. Atrium shows you the act — the real artifact — beside the prose that produced it. Nothing reaches production without passing this preview.
The full detailed chart. Condensed for print legibility in the book; shown here at full size.
The decision is a breath-gate: a deliberate human approval that records who approved, when, and against which sealed source — so the approval is as checkable later as any artifact. The thing you approve and the thing that ships are the same object.
The gate, with the real artifact in viewready
What this means for you
The human approves the real change and the approval is itself a receipt. What this means for you: of any change in production you can always answer who decided it, when, and from which source — the audit trail a successor inherits, already written.
Here's a real, sealed breath-gate from this book's own construction:
A sealed human gate
whata rendered change, previewed in full
approved bya named human (primacy)
againstthe exact sealed source version
the approvalitself a receipt
The determinism removes the drift; the gate keeps the human.
For the technical reader — the command, and how to verify it yourself
# one line · you do not need to run this see walkthrough
preview -> breath-gate -> sealed # -> a human approval that is itself a sealed receipt
Full step-by-step is in Appendix RX: Hands-On Demonstrations in the book.
ⓘDeterministic demonstration. The conversation is a faithful dramatization of the exercise; the receipt is the artifact it produces — the same every time, because the system is receipted. (Representative of the demo's structure; the production page renders the captured run.) No output here is fabricated. A live "run it yourself" mode is coming.
