●●●BangerWizardryBig Brain

Orthogonal Procrustes migration means embedding model upgrades without reindexing.

Strengths
  • •arXiv paper (EMNLP 2025) backs the Procrustes migration technique with verifiable claims
  • •Three commands replace throwaway scripts with dedup, incremental refresh, cost tracking
  • •Shadow mode with deterministic mock vectors enables local dev at zero API cost
Weaknesses
  • •Spark dependency limits adoption for teams not already on PySpark infrastructure
  • •Zero stars on GitHub suggests very early stage despite paper publication
