What Is It?

An Exit is a navigation link connecting one room to another. In MOOLLM's spatial architecture, exits are the EDGES of the memory palace graph.

Exits can be:

• Simple — just a destination
• Guarded — require conditions to pass
• Hidden — discoverable through exploration
• Metaphysical — conceptual rather than physical

Pie Menu Topology

Don Hopkins' pie menu insight: direction IS meaning.

| Direction | Purpose | |-----------|---------| | N/S/E/W | "Highway" links to major rooms | | NW/NE/SW/SE | "Grid" links to expandable sub-rooms | | UP/DOWN | Vertical transitions | | IN/OUT | Conceptual transitions |

Cardinal directions form the spiderweb — the main navigation network. Diagonal directions form grids — expandable arrays of sub-rooms.

Guard System

Guards are natural language conditions that control access:

guard: "player has the brass key"
guard_js: "(ctx) => ctx.player.inventory.includes('brass-key')"
guard_py: "lambda ctx: 'brass-key' in ctx.player.inventory"

The guard field contains human-readable intent. The guard_js and guard_py fields contain compiled code.

The adventure compiler emits COMPILE_EXPRESSION events for guards that need compilation.

Memory Palace Integration

From Frances Yates' "The Art of Memory":

"The method of loci places items at specific locations along an imagined journey."

Every exit is a doorway in the memory palace. The direction encodes meaning. Players navigate by spatial memory.
