The 60-second Closeout model

Current project records → permitted section selection → background generation → ZIP archive → review and handoff

• A Closeout package is a generated snapshot, not a live shared workspace.
• Section choices are remembered on the device for the next generation.
• Only sections available under the creator's permissions and organization packages appear.
• Constructable prepares one package at a time per project.
• The generated list preserves prior package records with creator, date, status, progress, and download when complete.
