  "description": "Referee: put an authored quest into play.\n\nThe first of the four commands that drive an adventure's quest state: a\nper-quest status that runs `inactive`, then `active`, then `completed`, and,\nunder it, a revealed/complete pair per objective. That state is engine-owned\nsession state beside the flag store, and these four are its only writers, so a\nreplay rebuilds it by re-executing the log.\n\nQuest and objective ids are a **closed domain**: they resolve against the\nadventure's `QuestSpec`s, and an id no quest\nspec defines is rejected. That is the deliberate opposite of\n`MarkTriggerFired`'s open trigger id:\na mark is bookkeeping a game may drive with ids from its own systems, while an\nactivated quest is projected into the player view with a name, an offer, and an\nobjective list, and an id with no quest behind it has none of them.\n\nAn accepted activation appends the quest's `offer` beat to the journal when its\nauthor wrote one, and the event includes the same line. The append emits no\n`JournalEntryAddedEvent`, because\nthe lifecycle event *is* that beat's event. Quest state is monotonic, so only an\n`inactive` quest activates. Referee commands are legal in every mode, terminal\nmodes included.\n\nModes:\n    `town`, `exploring`, `encounter`, `battle`, `game_over`, `victory`\n\nRejections:\n    - `session.command.unknown_quest` - `quest_id` names no quest of the\n      adventure.\n    - `session.command.quest_state` - the quest is already active or already\n      completed. The rejection names the quest and the state that refused it.\n\nEvents:\n    `QuestActivatedEvent` with the\n    quest id, the quest's name, and the offer beat.",
