# Publish only tables that pass their tests

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Data quality tests](https://agentwranglers.se/playbook/data-engineering/data-quality-tests.md).

- Rule: Build each table where no dashboard reads it, run its tests, and swap it in only when they pass. When a test fails, dashboards keep the last good version.
- Check: Break a model on staging so that a blocking test fails. The dashboard still shows the previous numbers, and an alert names the failed test.
- How: This pattern is called write, audit, publish. Build into a staging schema or a branch and run the tests from [Test the keys and values of every model](https://agentwranglers.se/playbook/data-engineering/data-quality-tests/model-tests.md). Then swap with one rename or view change. Tests that run after publishing find bad numbers people have already seen. Write next to each test whether a failure blocks the swap or only warns.
