# kaal:position:2026-09-21-013

**Affirmed position.** When generation becomes cheap, the binding constraint moves to evaluation. A calibrated score prices an error but does not make anyone answer for it. The successor to RLHF is the signal someone is willing to stand behind.

**Status.** affirmed  **Published.** 2026-09-21

**Holds when.**

- TypeSafe's post announces a product. It is not an empirical test of these claims.
- The position is Kaal's own argument in the essay After RLHF Comes a Stack, Not a Model.
- The position does not evaluate Jev's accuracy, which TypeSafe has not published a calibration figure for.
- The accountable-validation layer is proposed, not tested: no policy has yet been trained under it.
