scenario: ground/gr-p05-solve-legality
description: >
  GR-P05, ruled by ground-game 2026-08-03: SOLVE is legal only where it
  can do something. P1 holds no Clarify and is refused Problem 1; P2
  holds one, is admitted, and claims it.

  The prior-round-claim half of GR-P05 is asserted in
  `bot::tests::validate_enforces_all_four_solve_conditions` rather than
  here, because reaching a second round costs a dozen commands to test
  one rejection.

  The rule is asserted here rather than only in `legal_commands`, because
  a rule enforced by the offer alone constrains only clients that ask what
  is legal — a scenario file would walk straight past it. That is what the
  AM-1 coverage gate surfaced when GR-P05 was added with no scenario.
