  "description": "Referee: roll a dice expression through the seeded session.\n\nAn authorial roll for freeform adjudication. The referee resolves a *chance*\noutcome the content model can't express (a puzzle, a bluff, \"does the frayed\nrope hold?\") by rolling through the engine rather than inventing a number, so\nthe result is logged, replayable, and grounded in a typed event. Referee\ncommands are legal in every mode, terminal modes included. The roll draws from\nthe dedicated\n`ADJUDICATION_STREAM`, so an ad-hoc\nreferee roll never perturbs the draw sequence of keyed mechanics. A malformed\n`expression` is rejected at construction, exactly as\n`SpawnMonsters`'s `count_dice` is, so it\nnever reaches the session and consumes no draw.\n\nModes:\n    `town`, `exploring`, `encounter`, `battle`, `game_over`, `victory`\n\nRejections:\n    None.\n\nEvents:\n    `DiceRolledEvent` with the\n    expression, the total, and the individual die results.",

It's what `parse_command` and the\n`AnyCommand` union read to rebuild the right class\nfrom a serialized mapping, and it stays the same across releases."
