3> Pure astrometry + astrology engine — ephemeris, sky, sundial, tides, transits — in Rust, with a [Llimphi](https://gitea.gioser.net/sergio/llimphi) UI.
4
5`cosmos` computes the sky. Around a core astrology engine sit independent astrometric extracts — `cosmos-ephemeris`, `cosmos-sky`, `cosmos-sundial`, `cosmos-tides`, `cosmos-transits`, `cosmos-pointing` — that serve sundial / tides / navigation / planning without touching the chart machinery. A GPU UI (`cosmos-app-llimphi`, `cosmos-canvas-llimphi`) renders charts, sky maps and a dense starfield.

9```sh
10cargo run --release -p cosmos-app-llimphi              # the chart/sky desktop app
11cargo run --release -p cosmos-canvas-llimphi --example dense_starfield

14## How dependencies work
15
16cosmos is a full app: its UI integrates notebooks, panels and content-addressed sources. Llimphi and every foundational dependency are pulled as git dependencies from the [`gioser`](https://gitea.gioser.net/sergio/gioser) monorepo — the suite's source of truth. The astrometric core crates (`cosmos-ephemeris`, `-coords`, `-time`, …) are pure compute with no UI deps.
