The 24 mountains chart their 流年: dun and ju come from a transcribed table, and the 用柱 follows the 五鼠遁 of the seat’s mountain branch and the year stem.
15° per mountain in three 5° bands; the pillar’s branch is fixed by the mountain and its stem derived from the year stem via 五鼠遁; 旬首/值符/值使/void/horse all follow the 用柱.
Layer order: spirit · star · heaven stem · earth stem · gate. Solid border = value star, dashed = value gate.
The tradition's own line for the value star and value gate on this plate — literature, not advice.
