Create story arc
Create a Story Arc (quest) - the game-narrative pack’s label for the underlying quests entity. Starts in offered status by default; non-D&D systems may use a different lifecycle.
Mirrors POST /v1/projects/{project_id}/quests in the ttrpg-gm pack - same underlying QuestRepo, same response shape. Pack-gated to game-narrative so the dashboard’s pack-aware client picks the right URL without leaking ttrpg-gm-only endpoints to game-narrative tenants. See docs/conventions/pack-flavored-rest-urls.md.
