pub fn classify(tool: &str, input: &Value) -> Option<Steer>Expand description
Classify one tool call — its tool_name and tool_input object — into
the Steer that serves it, or None to allow. The Bash command is
classified by analyze; the harness’s own Grep / Glob / Read
calls are steered from their structured fields. Shared by process and
log_record; an unhandled tool or a missing field yields None.
