  • crystal_build_procurement_shortlistBuild a deterministic shortlist across requested crystal categories.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Build a deterministic shortlist across requested crystal categories. Verified products are limited to catalog bracelets; other categories remain clearly separated advisory items.
