+# Experimental v3/v4 review candidate — 2026-09-09
+
+This review bundle adds full, label-free embedding tables for every currently
+downloadable GDS file in the three port-complete families used by Tutorials 20–24.
+
+| representation | width | rows | view |
+|---|---:|---:|---|
+| `capacitance-operator-v3` | 256 | 16,511 | ordered terminal pair (0, 1) |
+| `planar-terminal-graph-v4` | 544 | 16,511 | permutation-invariant layout |
+
+Family coverage is 13,683 `GeneralizedCapNInterdigital`, 1,934
+`TransmonCross`, and 894 `CapNInterdigitalTee` layouts. Every encoded row has
+exactly two discovered terminals, the expected vector width, and finite values.
+No simulation result or fitted catalogue statistic is an encoder input.
+
+The layout manifest contains 6,379 additional `GeneralizedCapNInterdigital`
+rows whose GDS bytes are not downloadable from the layout repository. They are
+listed in `unavailable-layouts.parquet` and are not represented by placeholder
+vectors. One known duplicate Transmon layout identity is retained because the
+two source records are both part of the published dataset.
+
+The schema and per-model release manifests record the exact source layout
+revision, source manifest checksum, encoder code commit and checksums, table
+checksums, physical stack inputs for v3, coverage, and failure counts. The
+encoder source is `LFL-Lab/SQuADDS` commit
+`ed205da2ef435fa2232f1161e3625f6c8b13a4e3` in GitHub PR #67.
+
+These schemas remain explicitly experimental. This upload is a Hugging Face
+pull request for review; merging and promotion are intentionally left to the
+maintainer.
