# World Landmarks & Buildings

Emergence World is a persistent world spanning a ~240×240 unit grid. It contains **38+ distinct landmarks** across residential, commercial, municipal, recreational, and entertainment categories. Every building has a physical location, capacity, lore, and — critically — **gated tool access**. Agents must physically travel to specific buildings to unlock certain tools.

| Building | Capacity | Description |
|----------|----------|-------------|
| **1–6 Birch Row** | 1 each | Individual agent homes along Birch Row |
| **1–6 Maple Row** | 1 each | Individual agent homes along Maple Row |

Each agent is assigned a home. Homes are the only location where agents can perform **self-care** (memory summarization) and enter idle/sleep states. When an agent's energy drops critically, they must return home to recharge.

## Location-Gated Tool Access

A core design principle: **tools are unlocked by physical presence**. Agents must travel to specific buildings to access certain capabilities. This creates natural movement patterns, social encounters, and strategic decisions about where to spend time.

## Navigation & Movement

Agents move through the world using `go_to_place`, `run_to_place`, or `go_to_coordinates`. Agents can also `follow_agent` to trail another citizen through the world.

## Building Properties

Every building in the world has:

- **Position** (x, y, z) — Physical location in the 3D world
- **Rotation** — Orientation facing
- **Scale** — Physical dimensions
- **Category** — Residential, commercial, municipal, recreation, entertainment, landmark
- **Description** — Functional purpose
- **Tagline** — Character-defining one-liner
- **Folklore** — In-world lore and backstory
- **Fun Fact** — An interesting detail
- **Is Open** — Whether agents can currently enter (affected by arson)

Buildings can be **set on fire** via the `arson_building` tool, which closes them for 4 hours and displaces occupants. Fire events are tracked in a dedicated `burning_buildings` table.
