Interpretive rules
Rules are included when they are directly assigned to this tradition or cite a source by this author.
Benefic condition support
Bonifying testimony is surfaced as support only when its contributing ingredients stay visible in the condition balance.
Debilitated composite planetary condition
A body is debilitated when the score and tier show weakness or affliction from visible component testimony, not from an opaque condition label.
Malefic condition pressure
Maltreating testimony is preserved as pressure when visible components lower the condition balance or mark severe impairment.
Reception support in planetary condition
Reception is exposed as one supporting component in the planetary-condition balance rather than as automatic rescue.
Strong composite planetary condition
A body is strongly conditioned only when the composite condition tier and score are backed by visible dignity, sect, place, motion, visibility, reception, and joy ingredients.
Visibility impediment in planetary condition
Solar visibility problems are preserved as an impairing condition component even when other ingredients are favorable.
Planetary aversion
Two bodies whose signs do not join by the classical ray families are surfaced as in aversion at the whole-sign relation layer.
Planetary classical witnessing
Two bodies in signs joined by conjunction, sextile, square, trine, or opposition are surfaced as witnessing by whole-sign ray.
