A chart is a system, not a label generator
A single planet or sign can offer a useful entry point, but it does not describe the whole person. The same symbolic function can develop differently under different conditions and histories.
Context changes expression
Family, education, relationships, work, culture and life stage influence how a structure is expressed. Interpretation must therefore compare the chart with lived evidence instead of forcing every behaviour into one keyword.
The goal is a testable structure
SPISPIA aims to connect symbolic material with psychological function and observable choices. The result should remain open to checking, correction and the person’s own agency.
