"""Synthetic user scope for partner runtimes.

A partner is executed as a *synthetic user*: its workspace
(``data/partners/<id>/workspace``) is laid out exactly like a chat user
workspace, and every service that resolves paths through
``get_current_path_service()`` (rag, skills, notebooks, memory, task
workspaces) transparently reads the partner's own assets once the partner
scope is installed via ``user_context(...)``.
