I had to paste this into Claude and ask it to filter out the core idea. Here's the most important paragraph quoted from the article:

> The one repository with working CI has a workflow file of about 40 lines that runs a type check, the test suite, and a build on every pull request. Sixteen other repositories use the same test runner. Copying it sideways is an afternoon.

So I think they're saying that they never wired up CI, and as a result the value provided by their test suite in preventing bad code from shipping is limited.
