The Siblings Palace can describe peer collaborators, and Tian Ji draws attention to arrangements that may change, but it does not prove that a partner is unreliable. Two designers sharing a printer need clear rules for booking, supplies, and damage.
Set usage and cost rules
Write down booking, time slots, supplies, maintenance, and repair handling in a shared record, and confirm each temporary change. The Siblings Palace describes peer traits and the stars may suggest friction, but they do not judge whether someone is trustworthy or replace a contract.
Limit outside borrowers
Clarify who may borrow equipment, whether there is a charge, and how damage is handled, distinguishing close peers from the wider social circle represented by the Friends Palace. Read the natal Siblings pattern, then the supporting palaces and annual layer; written rules remain the practical basis.
