What this page can establish
This article explains method variation from the versioned implementation boundary. the approved implementation selects ziwei.default and describes other reference methods as potentially incompatible for specific boundaries. It does not choose between schools through prose or majority voting. It does not add traditional interpretation that is absent from the repository sources.
Independent example
The trusted-source note says a comparison tool cannot settle late-Zi, solar-term, timezone, true-solar-time, leap-month, or complete star placement differences. The example is a boundary register, not a ranking of traditions.
Figure specification
Figure 10: a boundary register listing comparable facts, method-incompatible facts, and the reason each comparison is limited. 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.
