+## Universal geometry model `v1`
+
+`universal-geometry-v1` is an additive 512-dimensional standard built from only
+a GDS file, a functional layer-role mapping, and the native design-parameter
+dictionary. Simulation targets are never embedded.
+
+| Block | Dimensions | Contents |
+| --- | ---: | --- |
+| Geometry metrics | 64 | 32 physical and morphological metrics plus their availability mask |
+| Multiscale shape | 320 | Five functional 64×64 channels compressed to the lowest 8×8 orthonormal 2D DCT coefficients |
+| Parameter controls | 128 | Stable signed feature hashing of canonical parameter paths and unit-normalized values |
+
+The five shape channels represent conductor, etch, ports, signed functional
+material, and signed distance to the functional boundary. The metric block
+retains physical scale; the shape block captures topology without storing a
+dense pixel tensor. Each block is normalized independently.
+
+Parameter identity is retained on every row through `parameter_names`,
+`parameter_values`, `parameter_hash_indices`, and `parameter_hash_signs`.
+`models/universal-geometry-v1/control-map.parquet` provides the global,
+auditable bridge back to the originating layout controls.
+
+This first v1 configuration contains all **20,062**
+`GeneralizedCapNInterdigital` designs. The encoder accepts foreign GDS layouts
+when their `(layer, datatype)` pairs are mapped to `conductor`, `etch`, or
+`port`; the cross-component reference normalization will be frozen in a later
+release after it is calibrated on the full SQuADDS catalogue.
+
+The complete input contract, block offsets, transforms, normalization
+statistics, and invariances are frozen in
+`models/universal-geometry-v1/schema.json`.

 SQuADDS_DB rows can resolve the same vector directly with
-`SQuADDS_DB.get_layout_embedding(row)`. The SQuADDS MCP server also provides
+`SQuADDS_DB.get_layout_embedding(row, embedding_version="v1")`. Omitting the
+version preserves the v0 default. The SQuADDS MCP server also provides
 `get_layout_embedding` and `find_similar_layouts`.
