task-system (placeholder)

This name is reserved by Spheriously to prevent dependency confusion. The real task-system package is private and is installed from source, never from this index.

Importing this placeholder raises ImportError on purpose: if it ever executes inside a Spheriously environment, an install path reached the public index instead of the sibling checkout, and that is a defect worth failing loudly on rather than resolving quietly to a package that does nothing.
