Field notes
The workflow separates training from qualification: weaknesses can be used to generate harder practice scenarios, while final tests use unseen work and fixed pass/fail thresholds.

It also publishes a manifest root and points readers to a verification endpoint, though the reported aggregate results remain claims presented by the site.
