driftvane: composable RAG and agent drift detectors

driftvane identifies a crucial pain point in modern RAG systems—silent answer degradation—and proposes a practical, serverless Python solution. The technical approach is solid and extremely timely. However, as an open-source library launched just days prior to submission, it currently has virtually zero verifiable traction, audience reach, or active users. It fits squarely within the minimal traction calibration tier, though its strong market timing offers high potential for future adoption.
