The eye of the falcon.

The construction

Pack. Align. Reopen.

The floor rhombus gives a rhombic cell. Its face normals construct the cuboctahedron. A selected 24-bar linkage then contracts to an octahedron, opens into a triangular net and folds into a tetrahedral pyramid. At mirror lock, a tracked triangular face becomes the head of the geometric falcon.

The polar-dual construction, bar-preserving fold and change of reference are distinct operations. Their staging joins them into one teachable journey.

The reference handover

The eye stays with the traveller.

On departure, Sol is the eye, Sirius and Ross 154 mark the spirals, and Alpha Centauri supplies the third reference. Ross 154 is a waystation. On return, Ross is the eye, Sol is the known spiral, and the other two references remain unknown.

These are supplied interpretive roles in an authored diagram. The spacing is a display scale, not an astronomical distance. The falcon is a visual carrier; it has not been derived as a discrete constellation of the 81 addresses.

Exact state

All 81 values return.

The held preparation is a 78-step numerical sequence. The receiving chart relabels the same field. On return, the chart and preparation are reversed. The added experience receipt is a separate record, so restoring the original array need not erase the record of the journey.

What the light means

A declared visualization.

The numerical field and return can be tested. Mirror timing, camera magnification, organic wings and the light of memory are authored visual choices. Their joining is a teaching schedule, not a demonstrated physical transport law.
