Overview

Cardinal modality links Aries, Cancer, Libra, and Capricorn with starting, redirecting, and establishing a new phase. The page separates calculation from interpretation and keeps this worked result conditional: four placements occupy Aries, Cancer, Libra, and Capricorn; the dated initiation log is contextual evidence rather than part of sign membership. Verification follows this declared method: Mark placements in the four cardinal signs, distinguish initiation from completion, and test whether angular houses repeat the starting emphasis.

Definition and exact scope

Calculation or decision rule

mark placements in the four cardinal signs, distinguish initiation from completion, and test whether angular houses repeat the starting emphasis

Worked case and illustrative near miss

☉ 2°♈, ☽ 14°♋, ♀ 21°♎, ♂ 7°♑; a quarterly log separately marks who initiated each launch, move, agreement, or deadline. four placements occupy Aries, Cancer, Libra, and Capricorn; the dated initiation log is contextual evidence rather than part of sign membership.

Illustrative near miss: Calling an angular Taurus planet cardinal; angularity describes prominence, while modality membership comes only from the sign table.

School and variant boundary

Membership is stable inside the declared tropical-sign framework, while weighting and meaning vary by school.

Product, safety, and verification boundary

OpenFate can connect Cardinal Signs to the natal chart and reading flow where supported; the connection supplies evidence, not a guaranteed life result. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Cardinal Signs cannot diagnose a person, remove consent, or guarantee an event.
