Building

buildings/<id>.ron — OURS; building TYPES for worldgen to instantiate.

Field	Type	Required	Description
build_cost	any[][]	required	Future-construction data with NO consumer yet (README).
furnishings	any[][]	default []	The type-appropriate genesis furnishing: `(goods/ id, count)` a venue of this type is dressed with — the good must carry a `furnishing:` block. Empty = the default domestic dressing (the `house` type's list).
id	string	required
name	string	required
requires	string[]	required	Terrain tags, ALL required (a conjunction); `[]` = anywhere.
rooms	RoomSpec[]	optional	The building's ROOM PROGRAM (designer-ruled moddable): the roles its floor plan claims, in claim order (biggest room first). Role names are OPEN vocabulary — the engine branches only on the mechanical flags, so a modded type may declare any rooms it likes. Empty = the default domestic program (the `house` type's).
source	Source	required
storage	boolean	required	True = the venue can stockpile goods.
storeys	integer	optional	How many storeys the type raises (1..=3, validated); the engine still gates upper floors on footprint mass. Default 1.

Nested shapes

Every shape Building closes over, so this page stands alone.

RoomSpec

One entry of a building's room program: the role NAME is open modder vocabulary (the narrator's word, the furnishing router's address); the FLAGS are what the engine's code branches on.

Field	Type	Required	Description
public	boolean	default false	The PUBLIC room: claims the entrance, and opens to every room it touches (the taproom rule). Exactly one per program (validated).
role	string	required	The role's name — free vocabulary ("taproom", "laboratory"…): the address a furnishing's `rooms:` list routes to.
upper	boolean	default false	May this role live on an upper floor? Ground-only when false.
