Product structure and general principles can be open.
Clients, releases and customer-specific documents need managed access.
Status should look live only when monitoring is actually connected.
Explain product and workflows without exposing owner internals.
Start from the concrete operation or problem type.
Tie packages to version, platform and release context.
Separate documented facts from open release gates.
