A result should show how far its evidence goes.
We publish the method, tested scope and limitations behind a result. We do not recycle a historical benchmark as a current accuracy guarantee.
Current Japanese evidence status
The current method has a frozen 142-sample validation set used during method selection. Because that set influenced the method, it is engineering evidence—not an independent estimate of current product accuracy.
An isolated, blind held-out run has not yet passed the release gate. Current Japanese FPR, TPR, AUC and accuracy figures are therefore withheld.

What must happen before a number is released
Collect independently
New permitted samples are kept separate from every corpus used to choose engines, prompts or thresholds.
Freeze and blind
Text hashes, scenario metadata and a cost ceiling are frozen; labels stay sequestered until the method run completes.
Measure the task
The report includes FPR, TPR, AUC, location recall/fallout, sample counts and 95% confidence intervals.
Release one record
Only a reproducible run bound to the current method version can unlock numeric claims on this page and in results.
What this evidence cannot establish
A detector result cannot prove who wrote a document.
Performance in one language or writing scenario cannot be borrowed for another.
Partial or degraded scans carry narrower evidence than a full current-method scan.
Any method, provider or threshold change requires a new versioned evaluation.
The current method has a frozen 142-sample validation set used during method selection. Because that set influenced the method, it is engineering evidence—not an independent estimate of current product accuracy.
