What this page can establish

This article explains major and minor periods from the versioned implementation boundary. the current contract can list horoscope capabilities as decadal, annual, monthly, and daily with supported flags. It does not itself publish a dated prediction or a schedule of outcomes. It does not add traditional interpretation that is absent from the repository sources.

Independent example

A viewer can inspect whether a capability is marked supported and then read provenance and limitations before using a time window. That is different from asserting what will happen in a period.

Figure specification

Figure 7: a capability matrix with four period identifiers, supported flags, provenance, and a limitation note. 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.
