Analysis

Written by an AI model from the sources above. It is a reading of them, not a source in its own right: every figure in it points back to a numbered source, and where the two disagree, the source is right.

Assessment

Confidence
documented a published ruleset or rule description exists and is cited
Evidence
partial sources agree on some points but disagree or say nothing on others

Cross-comparison

What each source was read to say, set side by side. The numbers are the sources above.

  • [1] the scorecard is published annually by both the National Mah Jongg League and the American Mah-Jongg Association; the AMJA card is the second of the two
  • [2] describes the annual card as an artefact and how the NMJL and AMJA cards differ in form
  • [1] the AMJA is named alongside the NMJL as one of the two bodies publishing an annual card, and the two are described as having minor scoring differences
  • [3] not relevant to this node; recorded only to note that amja.net itself could not be read, its TLS certificate having expired, so no primary source for this node was obtainable

Reading it

Two sources confirm the AMJA card exists as the second of the two annual American cards and that the NMJL and AMJA differ in minor scoring details. The association's own site could not be read: amja.net serves an expired certificate, and it was not fetched over an unverified connection. So the node is attested but not primary-sourced, and no source read here describes how the two cards differ in practice.
