The bug that passes every test and does nothing. I let an AI write more than I read, and the tests that would have caught all of it.

Six real silent failures from 14 months of shipping alone, the week I let an AI write more than I read, and the tests that would have caught all of it.

A crash is honest. It tells you something went wrong.

Silence is also a claim. It says everything went fine.

That claim is far more expensive when it is false, and it is the one we are now producing at scale.

I have shipped a Windows system monitor in public for fourteen months, alone, in the evenings after work. Everything is on GitHub from the first commit, so this is a record I cannot edit. Here are six failures from it, none of which crashed, all of which passed every test I owned.
