# Step 9Q — Shared Dwellings & Multiple Occupants

## Clean Upload
This package extends the confirmed Step 9P baseline.

## Methodology
Book-v1 Section 10 states that the dominant vibration of a shared dwelling is calculated from the sum of all residents’ Life Paths plus the address number, with the result reduced while preserving Master Numbers. Its example is 2 + 5 + 4 = 11.
