Cargo CLI — Segmentation

Segments are the audience layer of a Cargo workspace: a named, saved filter over one model that answers "which records do I mean?" Everything downstream — a batch run, a play trigger, a CSV export, a change feed — takes a segment (or a segment-shaped filter) as its input.

See references/response-shapes.md for full JSON response structures. See references/troubleshooting.md for common errors and how to fix them. Filter condition kinds and operators live in ../cargo-orchestration/references/filter-syntax.md — the single source of truth for filter JSON.
