# kaptein-viewmodel
The renderer-agnostic domain layer — the product. It owns all *semantics*: columns,
sorting, filtering, status inference (including view-definition/lens evaluation),
permission decisions, and action graphs.
Frontends (TUI, GUI, headless, serve) consume the render contract defined here and own
only *geometry*. This crate is wasm-pure.

Date).
