Commander’s manual · Rules v3
10 Placement rules
After every installation, removal, and exchange, the whole station must satisfy all of these rules:
- Every module occupies one node, with its inward marker toward the Command Core.
- Every module has a continuous corridor route to the Command Core.
- Every middle-ring module is supported by at least one installed module in the inner ring, in the same sector or an adjacent sector.
- Every outer-ring module is supported by at least two installed modules in the middle ring, in the same sector or adjacent sectors.
Support depends only on which nodes are occupied; a supporting module does not need a corridor to the module it supports. Sockets do not have to match. Empty nodes anywhere on the board are legal, including nodes surrounded by modules.
Figure 3 · Placement
Solid pods are installed. The dashed pod is a candidate placement being checked. The heavier bridges trace one corridor route: from the outer-ring Observatory in sector 1 inward to the Laboratory, inward again to the Greenhouse, and into the Core.
- Legal. A middle-ring Reactor in sector 0. It is supported by the inner-ring Habitation in the same sector (rule 3) and reaches the Core through its inward corridor (rule 2). Its clockwise bulkhead meets the Laboratory's counterclockwise port: a sealed contact, which is legal.
- Legal. An outer-ring Observatory in sector 1, supported by two middle-ring modules in sectors 0 and 1 (rule 4), with the highlighted corridor route to the Core (rule 2).
- Illegal. An outer-ring Habitation in sector 6. Only one middle-ring module stands in sectors 5, 6, or 7, and rule 4 requires two. Its corridor inward would be fine; support is what fails.
