                  carrying file, line, and test counts. Crate identity, workspace membership, and \
                  cargo target kinds are authoritative (read from `cargo metadata`); file/line counts \
                  are exact; the module bucketing and the #[test] tally are heuristic (marked ~ in the \
                  output). With no --group, the contextual group type is inferred from the given path's \
                  Cargo.toml (a [workspace] table vs a lone [package]). See `ct-survey --explain` for \
                  agent-oriented documentation."
