# DEVİM Eval

This repository documents DEVİM's evaluation methodology and evaluator failures. It does **not** release hidden holdout items.

A central research lesson in DEVİM is that evaluator quality is part of the scientific problem: a model can improve language modeling while a capability instrument stays flat, and a seemingly useful QA task can turn out to be solvable by copying.

## Frozen V1.8 evaluator

Public-safe facts:

- Evaluator: **DEVIM_TR_CAPABILITY_V1_8**
- Forced-choice items: **2,000**
- Validator: **32 / 32 PASS**
- Hard contamination detected: **0**
- Blind audit: **75 CLEAN / 5 AWKWARD / 0 HARD**

The hidden item bank itself remains private to preserve evaluation integrity.

## Why evaluator failures are published

DEVİM's QA diagnostic exposed a copy confound: the interface could not cleanly distinguish target capability from mechanical extraction. That experiment was treated as evaluator evidence, not as a model victory.

The current public principle is:

**research metrics are not automatically leaderboard benchmarks.**

A trustworthy public benchmark requires frozen definitions, contamination controls, validated scoring, and a release boundary that does not leak the hidden holdout.

## What may be published here

- evaluator methodology
- schemas and validators
- scoring code when safe
- contamination-check methodology
- public example items
- evaluator version history
- negative results and known confounds

## What remains private

- hidden V1.8 holdout items
- sequestered evaluation material
- private prompts/contracts
- any artifact whose release would invalidate future measurement
