The defining loop of a genuine external project, proven end-to-end and green on arrival: a fresh aura-new project authors an OPEN blueprint over its own node (knob_lab::Scale, factor unbound); --list-axes shows the axis, a real-data GER40 sweep over it yields two members whose manifests carry the project-node binding, the family persists and reproduces 2/2 bit-identically, and one campaign cell over the same blueprint runs to exit 0 linking a sweep family. No implementation was needed — the loop already worked; this pin is the previously-missing evidence (the deepest exercised path before was a single param-less aura run). The axis-discovery leg is un-gated so the test stays meaningful on a data-less host. closes #235
