1,618 green checks and nothing has ever run

I counted the tests on a system I have been building for a few weeks. 1,618 passing checks across thirteen suites. Then I counted how many times the thing has actually run start to finish, doing the job it exists to do. Zero.

Both numbers are true at the same time, and that took a while to sit with. The tests are not fake. Each one measures a piece in isolation, and each piece works. What none of them can tell me is whether the pieces connect, because none of them was ever asked that. A green suite is a claim about parts. I had been reading it as a claim about the whole.

The part I like less is why it stayed that way for three weeks. Building an adjacent component is pleasant work. There is a clear next step, it goes green, the count climbs, and I have something to point at. Running the whole line means watching it fail somewhere I have not thought about yet, in a way that does not come with an obvious next step. So I kept building things next to it instead.

I have not fixed this. The plan is to push one thing all the way through, end to end, and see where it stops. That is the only measurement here that means anything, and I have known that for three weeks without doing it.
