scenario: ground/gr-e01-threshold-unreachable-2p
description: >
  GR-E01's threshold against the standard preset's Problem values, at the
  2-player boundary. Both Problems are claimed — the best case available
  — and the total is 3 against a threshold of 5. With the placeholder
  fixture (value = priority) group success is unreachable at 2, 3 and 4
  players; only 5–6p can reach its 9. Recorded here so the gap has a
  failing-in-fact scenario rather than a paragraph, and marked provisional
  because the fixture is explicitly a stand-in for scenario Problem data.
