What this page can establish
This article explains a normalized chart from the versioned implementation boundary. the chart contract requires exactly twelve uniquely identified palaces, a life palace identifier, a body palace identifier, transformations, warnings, and provenance. It does not add traditional interpretation that is absent from the repository sources.
Independent example
Use the reviewed solar-lunar fixture: its output records twelve palaces and explicit branch identifiers. Inspect those identifiers as fields, not as a statement about a person.
Figure specification
Figure 1: a contract diagram listing twelve palace identifiers, the selected life and body identifiers, transformations, warnings, and provenance. The figure is an explanatory diagram, not a generated natal chart and not an instruction to make a personal decision.
Limits
The current application uses iztro 2.6.0 with ziwei.default, preserves input precision and warnings, and records documented gaps. It does not independently validate true-solar-time correction, every school variation, or traditional meanings outside the mapped fields.
