and still be wrong about Japan.
Every industry here runs on conventions that were never written down in English, and the people who know them are not the people producing training data.

Name the task →02 / Quality
You should not have to take our word for the quality.
- Agreement (κ)
- Two qualified reviewers score every example independently, and the figure comes with the batch.
- Rework rate
- Counted on the batch you receive, and reported even when it is high.
- Audit log
- Every example traces back to who wrote it and who checked it.
03 / Method
Nothing here came off the internet.
Practitioners write up their own experience as anonymized cases. Nothing proprietary leaves anyone's building, and there is no way to reproduce this with a translation tool or a synthetic pipeline.
04 / Independence
We are in Tokyo, and no model team owns a piece of us.
Nothing you send here ends up shaping a competitor's roadmap. If your side needs the data to stay in Japan, it stays in Japan.
