# Adventure Contract prototype

Dependency-free TypeScript prototype for Node.js 22.14+ with explicit type
stripping.

- `adventure-types.ts` — genre-neutral HostPreferences, AdventureDraft, and
  output types.
- `adventure.ts` — host/draft boundary validation and deterministic
  compilation.
- `adventure-support.ts` — trigger derivation and stable contract hashing.
- `fixtures/sci-fi-comedy.ts` — separate original, non-canonical host brief and
  planner draft.
- `adventure.test.ts` — behavioral and adversarial checks.
- `demo.ts` — executable compile/validate summary.

The fixture is Technical R&D test data, not product canon. It contains no
borrowed setting, characters, rules text, or adventure material.
