BaZi and Zi Wei Cross-Reading

Read two verified charts for one person against each other and write cross_reading_<name>.md plus cross_reading_evidence_<name>.md. Compare; never recalculate either source.

Before writing either file, read and follow shared/report-presentation.md. It defines the common localization, data-card, and separate-evidence boundary rules; this skill defines what counts as agreement and how a disagreement must be recorded.

Route and source gate

• Raw birth details belong to bazi-chart and ziwei-chart first, in either order.
• One system alone belongs to bazi-reading or ziwei-reading.
• Two people belong to bazi-compatibility.
• Luck cycles, annual transformations, dated events, and forecasts are outside this release.

Require both of:

1. A chinese-metaphysics.bazi-chart JSON artifact at schema version 1 with a valid canonical checksum.
2. A chinese-metaphysics.ziwei-chart JSON artifact at schema version 1 with a valid canonical checksum.

Validate both in one run, BaZi first:
