# Game Crafter Prototype — Watershed v0.1

This folder holds the physical-game specification for the WaterStorage / Watershed system.

## Component target

- 10 phase cards;
- 10 matching action cards;
- 1 basin mat with Ocean, Clouds, Soil Surface, Streamlines, Creeks / Rivers, Lakes / Reservoirs, Groundwater, and Return zones;
- flow, pressure, pollution, energy, groundwater, reservoir, and health tokens;
- trace / seed card;
- player aid and solo rules.

## Build rule

The physical prototype must share its phase order and state effects with the CookieBlob prototype. Use `../parity-matrix.md` as the source of truth for action semantics.
