"""Domain packs for ToolFault-Bench.

Each domain describes a small tool environment plus *successful* interactions.
Fault templates (templates.py) take these clean interactions and inject faults.

Every scenario method takes a Ctx and returns a dict with at least:
    request : str          -- the user's request
    prefix  : list[Call]   -- earlier (successful) tool calls, oldest first
    call    : Call         -- the judged call, with its *normal* response
