Evidence safeguards

• Every record was selected by the evidence-safe candidate analyser after all resource, prerequisite, relationship and patient blockers were cleared.
• Patient maxima and optional minima, specialisation captions and IDs, UK codes, transport and critical-care probabilities, first-responder probability and end-of-mission generation flags are preserved exactly when published.
• Resource probabilities remain distinct from patient probabilities.
• Duplicate relationship multiplicity, variants, overlays, unsupported generators and unmapped keys remain blocked.
• Strict resource-key and patient equivalence are mandatory for every promotion.
