blueDelta manual

Compares two versioned lab run manifests, excludes only the candidates ruled out by an explicit dependency rule, and — given a test catalog — recommends the cheapest experiment that would separate what's left.

What this product is and is not

Is: Manifest diff and candidate minimization.

Is not: Never claims a surviving candidate caused the result, never runs an experiment or controls an instrument, and never infers from data the manifests don't contain.

Who uses it

Lab and research-integrity reviewers.

Getting started — the local demo

From the product's own repository:

make dev
make test

This runs entirely offline against synthetic fixtures and exits non-zero on any mismatch. It does not connect to any production data source.

What a receipt proves

A signed receipt proves what blueDelta ran and recorded; it does not prove an underlying real-world claim is true. Anyone can check the signature offline with the standalone verifier shipped alongside the product, without installing blueDelta itself.

Known gaps, stated plainly

Web UI exists but is not yet wired to the API (a later milestone).
V1 core has no learned ranking by design.

FAQ

Does blueDelta make the decision for me?

No. Never claims a surviving candidate caused the result, never runs an experiment or controls an instrument, and never infers from data the manifests don't contain.

Does blueDelta replace the system I already use?

No — it is an overlay. Your existing record system, LIMS, or claims platform stays exactly where it is.
