app.MapPost("/api/nlp/sentiment", async (SentimentRequest req, PredictionEnginePool<ReviewRow, SentimentPred> pool, IAuditLog audit) =>
{
    var text = PiiRedactor.Mask(req.Text);
    var result = pool.Predict(new ReviewRow { Text = text });
    audit.Write(req.TenantId, "sentiment", modelVersion: "v3");
    return Results.Ok(result);
});
