Players can now paste the full text of a freely available adventure when creating a game, and the DM will follow it instead of inventing its own plot/NPCs/locations. Reuses the existing rulebook RAG pipeline (chunking, local embedding) rather than injecting the raw text into every turn, since real adventure modules range from a few pages to hundreds — far beyond what fits in a prompt. - New adventure_chunks table (game-scoped, unlike the global rulebook_chunks) + Game.adventure_text storing the raw source. - ingest_adventure_text() chunks/embeds synchronously during POST /api/games when adventure_text is non-empty. - build_adventure_rag_block() retrieves by similarity to the latest player message, scoped to game_id — plus always includes chunk 0 (the adventure's opening) regardless of the query, since early Session-0 messages rarely resemble the adventure's actual hook and pure similarity search could miss the beginning entirely. - System prompt instructs the DM to follow provided adventure excerpts strictly, deviating only when players clearly go off-script. - Frontend: optional adventure-text field in the game creation form, a has_adventure flag surfaced as a small badge on the game card and session header. Verified with an isolated two-game test that chunks/retrieval never leak across games (the critical failure mode here), and live against x.ai: a custom-written one-shot's specific NPCs, location, and hook appeared verbatim in the DM's opening scene instead of invented ones.
