Elder
Elder is a major-star label in PracticeEco’s deterministic chart implementation.
What the implementation can support
Elder belongs to the Treasury series. In the implemented rule it is five branches after Treasurer in the selected placement rule; its signed offset is 5. This is an inspectable placement relationship. The English word “Elder” is PracticeEco’s compact public label, not a literal translation and not a personality conclusion.
Across the same 43,200 equally weighted rule inputs used to audit the type catalogue, Elder participates in 4 public type arrangements, including 3 paired arrangements, covering 5,352 grid outcomes when direct and opposite-palace assignments are counted. This frequency belongs to the enumerated rules; it is not an estimate of people in a population.
When Elder appears on a visitor’s chart, the reproducible claim is limited to its branch, palace label, series relationship, and any transformation explicitly computed from the selected year-stem table. Meanings added beyond that require named sources and room for school differences. The free chart therefore shows the structure. Answers to the 24 questions come only with the paid report, which sets them beside the chart as a separate view without turning either side into proof of the other.

Use and limits
This page explains a rule, label, or product boundary. It is not a clinical instrument, a forecast, or a substitute for direct evidence about a person. Different Purple Star astrology schools can use different calendar and transformation choices.
