    # wt-024 M10 (AC-08): lowered from 1000 to 20 to prevent
    # runaway process churn from a wedged MCP server. Each restart
    # spawns a new subprocess, opens a log FD, creates a session
    # file, and runs preflight (TCP+HTTP+tools/list); 20 restarts is
    # generous for transient crashes while bounding the
    # per-invocation memory and CPU cost. The field is still
    # overridable by callers via ``McpRestartPolicy(max_restarts=N)``.
