+# aura-quadriga — an aura research project (data-only)
+
+This directory is an aura project: blueprints + research documents over the
+std vocabulary, anchored by `Aura.toml`. There is no crate and no build step.
+
+- Run:   `aura run blueprints/signal.json` (the starter is closed — all
+  params bound; bound values are defaults — any `--axis` may override them
+  (#246))
+- Sweep: `aura sweep blueprints/signal.json --axis aura_quadriga_signal.fast.length=2,4,8`
+  (`aura sweep <bp> --list-axes` lists the open + bound-overridable axes)
+- Native nodes: when the project needs its first project-specific node,
+  `aura nodes new <name>` scaffolds a node crate beside this project and
+  attaches it via `[nodes]` in `Aura.toml` (build it with `cargo build`).
+- Topology is data (`blueprints/*.json`); results land in `runs/`.
