A schema rename passed every unit test. It still broke a revenue dashboard.
The query changed from order_total to gross_amount; the schema was valid, but downstream models still expected the old field.
The fix isn't another linter. Before merge, ask four questions:
Which assets depend on this field?
Is the change additive, rename, type change, or removal?
Can we generate compatibility SQL and dbt YAML before touching production?
Is there a decision receipt reviewers can reproduce?
I built a bounded public replay of that workflow. Start with the CRITICAL case: it blocks a lossy decimal-to-integer change when an ML consumer sits downstream, then exposes the lineage, affected queries, compatibility artifacts, and deterministic run ID.

Fieldwork now works from request to approved quote.
Try the demo: https://launchinseven.com/samples/fieldwork
Enter a fictional service request, see the itemized estimate, then open Operations to edit the quote, review it and export a printable quote or CSV. Records survive a reload in your browser. The demo uses fictional data and local storage; a shared live system would need its own agreed backend and access controls.
The point is to make a business workflow concrete enough to test: what the customer enters, what the team reviews, what changes status and what leaves the system.
I direct scope and review; GPT-6 Astra handles implementation and many checks. This is an original working sample, not a paid client case.
If an existing web workflow is causing friction, message me on Contra with the URL or redacted screenshots and what should happen. We can agree a small paid first milestone—such as a documented workflow review or a defined interface fix—with its deliverable, fee, inputs and timing confirmed before work.
I'd keep a short change history beside the itemized estimate, so the team can see what changed before approval and which version was exported.
