Create a Project

Creates a Workspace-scoped Project from either an uploaded file tree (source.kind of upload, carrying 1–1,024 base64 file bodies at normalized relative paths) or a GitHub repository (source.kind of git, naming repository, connection_id, ref, and an acted_as Principal that owns the Connection and holds use_connection). Creation publishes revision 1 and returns the Project. Send an Idempotency-Key so a retry replays the same creation instead of publishing a second Project.

Checkfu support posture: alpha; hosted. Required evidence journey: project-mounting. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
