blueCatch manual

Blinds seeded error cases into a real review queue, imports the reviewer's actual decisions, and signs a scorecard of per-class catch rates with confidence intervals — scoring the process, never a named reviewer.

What this product is and is not

Is: What a review process actually catches.

Is not: Not a live covert-seeding tool, not an employee-surveillance product, and it never touches medical, legal, or financial production records.

Who uses it

Quality and review-assurance leads.

Getting started — the local demo

From the product's own repository:

make demo
make demo-ui   # to see the scored project in the web UI

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

Screen-by-screen walkthrough

Blinded review queue export Scorecard — per-class catch rates with confidence intervals

blueCatch Projects screen: a local project, blueCatch demo, listed alongside a form to create a new project, running fully offline on synthetic seeds. — Synthetic demo data
Blinded review queue export — blind known seeded error cases into an exported review queue, entirely offline.

blueCatch Process scorecard screen: 5 of 10 blinded seeds caught, with a per-error-class catch rate chart showing Policy Violation caught 5 of 5 and Subtle Misroute caught 0 of 5, each with a 95% confidence interval. — Synthetic demo data
Scorecard — catch rate measured per error class, with confidence intervals, never blended into one flattering score.

What a receipt proves

A signed receipt proves what blueCatch 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 blueCatch itself.

Known gaps, stated plainly

Scores a process, never a named reviewer, by design.

FAQ

Does blueCatch make the decision for me?

No. Not a live covert-seeding tool, not an employee-surveillance product, and it never touches medical, legal, or financial production records.

Does blueCatch replace the system I already use?

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