Shared work creates context
A person participates in a production, performs work and meets other people. That shared context can matter after the production ends. The professional network should retain useful relationship context without making a temporary production membership the permanent relationship object.
Production People answers who participates in this operational context. Personal Roster answers which professional relationships an individual deliberately retains. A community has still another membership and interaction lifecycle.
Saving a coworker
A conceptual path starts with a production, follows participation to the persistent person, then records a reviewed personal relationship. The saved relationship can help future work, while a future production still establishes fresh participation and assignments.
Saving contact information is not a bulk export of a production directory. Shared work does not imply permission to retain every private detail. Appropriate contact review and domain privacy remain part of the design.
Persistent identity without universal visibility
An identity connection can make records coherent without making them publicly discoverable. A public profile, a production directory and a personal roster are different presentations with different audiences. Linking them does not erase those boundaries.
The network model therefore resists two tempting shortcuts: recreating the person for every production, and exposing all shared-work history through one universally visible profile. The former loses continuity; the latter confuses identity with disclosure.
Costs
Persistent references need reconciliation and lifecycle handling. Relationship editing must be understandable, and people need a clear distinction between changing production information and changing a personal contact. These costs are the counterpart of a useful benefit: temporary work can contribute to a professional relationship without permanently owning the person or replacing future production authority.
The public site uses conceptual journeys rather than real crew records. No private customer or coworker data is included.
