The count is four, and the rule is a 3° orb. A sign group qualifies when its natal Sun, Moon, Mercury, Ascendant or 4th, 8th or 12th-house ruler sits within 3° of 16.89° Scorpio, or makes a hard aspect to it. Scorpio takes the conjunction, Taurus the opposition, and Leo and Aquarius the two squares.
The cross-check degrees tell you who else leans in without taking a direct hit. Mercury at 6.87° Scorpio is 10.02° from the lunation — near enough to color Scorpio's own story, too far to pull in another sign. Saturn at 8.81° Aries trines at a loose 21.92° orb. That is background pressure, not a headline.
Here is why the four-way split holds. The Sun and Moon square Mars at 22.68° Leo at a 5.79° orb, which keeps Leo in the frame without giving it the tightest contact. Mars sits 2.57° from Jupiter in the same sign, and that pairing adds appetite to Leo's square. Fixed signs meet this lunation at hard angles; the mutable signs get a lighter, less personal touch.
Your Sun sign alone does not decide this. A Scorpio born with the Moon at 2° Gemini is not standing on the pressure point. A Taurus with Mercury at 17° Scorpio is. The degree is the test, not the label.
One honest limit: a birth date cannot place your Ascendant or your house rulers, and the Moon's sign can be ambiguous on a day it changes. Enter your birth time and place in the birth chart calculator to get those layers right before you claim one of the four seats.
Each seat carries its own postponed yes. Scorpio postpones a disclosure about what they own or owe — a debt, a stake, a thing they have quietly let someone else keep. Taurus postpones a boundary with the person who relies on their steadiness and never hears a no. Leo postpones a creative or romantic risk that would expose them before it succeeds. Aquarius postpones a break from a group script — the role everyone expects them to play. Draw those four into the open, and the reset has done its work.
