T-Square
T-Square explains one opposition and two squares converging on a focal planet. ☉–☽ opposition 1°; ♂ squares each end by 2° and 1°; Mars is the apex.
Overview
A T-square requires an opposition whose two ends both square a third focal planet, forming three linked aspects rather than a visual resemblance. The page separates calculation from interpretation and keeps this worked result conditional: ☉–☽ opposition 1°; ♂ squares each end by 2° and 1°; Mars is the apex. Verification follows this declared method: Verify A–B near 180°, A–C near 90°, and B–C near 90°, then name the focal planet and the unoccupied opposing degree without inventing a missing planet.

Definition and exact scope
a T-square requires an opposition whose two ends both square a third focal planet, forming three linked aspects rather than a visual resemblance
Calculation or decision rule
verify A–B near 180°, A–C near 90°, and B–C near 90°, then name the focal planet and the unoccupied opposing degree without inventing a missing planet
Worked case and illustrative near miss
☉ 2°♈, ☽ 3°♎, ♂ 4°♋; all major-aspect caps set to 6°. ☉–☽ opposition 1°; ♂ squares each end by 2° and 1°; Mars is the apex.
Illustrative near miss: One opposition plus only one passing square is an open triangle, not a T-square.
School and variant boundary
A pattern exists only when every required geometric edge passes the same published inclusion rule.
Product, safety, and verification boundary
OpenFate can connect T-Square 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. T-Square cannot diagnose a person, remove consent, or guarantee an event.
