# Map Contract prototype

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

- `map-types.ts` — regions, locations, edges, viewer and move types.
- `map.ts` — static validation, reachability, projection, movement and LOS.
- `fixtures/sci-fi-comedy-map.ts` — original, non-canonical test fixture.
- `map.test.ts` — behavioral and adversarial checks.
- `demo.ts` — executable validation/projection/movement summary.

The fixture is Technical R&D test data, not product canon. Layout coordinates
are presentation hints; topology and edge contracts remain authoritative.

Run from the study directory:

```bash
node --no-warnings --experimental-strip-types --test prototype/map.test.ts
node --no-warnings --experimental-strip-types prototype/demo.ts
```
