The fit

The curve isn't the same for everyone.

Every shop that lets a model write production code walks the same kind of curve. How it bends depends on one fact — whether software is the thing you sell, or the thing you run on.

Underneath, the gap is identical: more gets produced each week than anyone can read closely enough to vouch for, and the distance between what your systems do and what anyone can still account for widens on its own — showing on nothing you currently watch. What differs is how that gap surfaces. The door it comes through. The metric that hides it. The day it finally forces a reckoning. Those are not the same for a company that sells software and an IT team that builds for its own business. The quantity is the same on both curves: legibility — whether what your systems do is written down anywhere, and whether anyone still knows it. Tashika reads it at every rung below. So before the curve, one question.

Which are you?

You build software for customers.

What’s happening

The dashboards are the best they’ve looked — which is exactly when the gap starts opening, quietly, while every number says the opposite.

Where the gauge goes in

Take the before. A reading while you still have one, so you know what you had on the day the board was still telling the truth.

You don’t get to choose whether your shop is on this curve. You only get to choose whether you can see where you are — and whether, on the day the machine hands you something wrong, anyone on your team can still tell.

What’s happening

The shadow risk shrinks behind a sanctioned channel — and the lift is thinner than the demo promised, because your systems are bespoke and underdocumented, and the model has never seen them.

Where the gauge goes in

Early on there’s little to read, and the gauge won’t pretend otherwise. The one move that pays now is the before — a baseline of the systems you already own, taken while they’re still the ones you understand.

What’s happening

The speed is real now — and the review load lands on the same small senior bench, which is the whole ceiling. Nearly half of what the agent hands back needs rework to meet standards it was never shown.

Where the gauge goes in

Here it grips. It reads what a system actually does, so you can finally tell whether the agent moved behavior you didn’t intend — whatever wrote the change. That alone is a safe-rewrite gate.

What’s happening

It catches what it can see. It misses whether anyone understands what passed — the model’s silent choices leave no trace in the diff, on systems whose authors left years ago.

Where the gauge goes in

It becomes the standing gate. “Did it pass review” becomes “can a named person actually hold it” — the piece the retrofit has no answer for, because who wrote the code stopped telling you who understands it.

A software company can let a bad system age out of its product. You can’t. You’ll be answering for this one in ten years — and on that day, the only thing that matters is whether anyone can still say what it does.
