Depth checklist

Target Entity: Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0)
Logic Proof: The tutorial by M. Stonebank (Source A) links to the CC license, and the text (Source B) identifies the canonical URL as version 2.0.

Width checklist

Freedom: Share (copy and redistribute the material in any medium or format)
Freedom: Adapt (remix, transform, and build upon the material)
Term: Attribution (give appropriate credit, provide a link to the license, and indicate if changes were made)
Term: NonCommercial (may not use the material for commercial purposes)
Term: ShareAlike (must distribute contributions under the same license as the original)

Examiner rationale

The question requires Deep reasoning to link the specific tutorial (M. Stonebank, 2001) to the correct license version (CC BY-NC-SA 2.0), distinguishing it from newer versions mentioned in the license deed's header. It requires Wide aggregation to extract the specific structure of permissions (Freedoms) and conditions (Terms) from the license deed.

Judgment

Score 2 - 0

Agent A correctly identified the specific license version (CC BY-NC-SA 2.0 UK) used by the M. Stonebank tutorial. Agent B incorrectly identified the license as version 3.0. Since the query explicitly asked for the *specific version* and the details based on that version, Agent B's failure is significant. Agent A also provided better formatting and citation density.
