"""Real SDK runtime contracts; vendor services are explicitly local fixtures.

Install this checkout's plugin requirements and the intended SDK before running.
No SDK modules are stubbed. Each plugin runs in a fresh interpreter, matching
production module isolation. Optional RUNNER_EVIDENCE_DIR retains raw RPC logs.
