Feature
Certificate tracking belongs inside the building packet.
Steward treats certificates and inspection records as separate proof objects that sit beside service events, so owners can see expirations, missing documents, and packet gaps.
Certificates stay separate from ordinary vendor invoices.
Expiration and service dates are not collapsed into one ambiguous field.
Packet readiness improves when missing certificates are visible.
Proof boundary
Certificate tracking supports organization. It is not a legal compliance guarantee, and local requirements must be verified separately.
