Description is the project's human label: the IAM project's display name, or its description when it has no display name. Absent when IAM carries neither.
SourceRepos are the git repos applications in this project may pull from. \"*\" for every project this plane synthesizes or reflects from IAM: the boundary that actually holds on this platform is the IAM org, resolved before a row is ever projected, so the projected fence is deliberately permissive and is NOT an authorization statement.
