All 17,727 v2 vectors are rebuilt against the regenerated layouts, in which every family now shares a fixed 169 um per-side ground margin.
The 14,899 rows belonging to families that were not regenerated (GeneralizedCapNInterdigital, CavityClawRouteMeander) are byte-identical to the previous release, verified element-wise rather than asserted. Correcting two families changed nothing for the other two because no v2 coordinate is derived from catalogue statistics.
Adds metric-v1, a frozen similarity transform. v2 coordinates are non-negative log-magnitudes in absolute units, so every device shares a large common direction and a raw cosine saturates; within TransmonCross the entire family spans a similarity standard deviation of 0.0005. metric-v1 is centre, scale, shrinkage-0.70 ZCA whitening, then cosine, fitted once on the reference catalogue and versioned separately so the vectors stay catalogue-free while the metric is shared. It retains 303 of 512 dimensions; the 209 it discards are…
Rebuild universal-geometry-v2 on the unified layout convention
TransmonCross and CapNInterdigitalTee v2 rows are rebuilt from the regenerated GDS that adopts the GeneralizedCapNInterdigital layer convention.
All 14,899 rows for the two families that were not regenerated are byte-identical to the previous release, verified before upload. Correcting two families changed nothing for the others because no v2 coordinate derives from catalogue statistics.
layout_id changed for the regenerated rows, matching the layouts dataset; design_id and source_id are unchanged. static-embedding-v0 and universal-geometry-v1 are untouched.
Extend universal-geometry-v2 to all four component families
Expands the v2 table from 13,683 GeneralizedCapNInterdigital rows to 17,727 rows spanning all four families: GeneralizedCapNInterdigital (13,683), TransmonCross (1,934), CavityClawRouteMeander (1,216) and CapNInterdigitalTee (894).
Every vector published in the previous v2 release is byte-identical here. Adding three component families changed none of them, because no v2 coordinate is derived from catalogue statistics.
Known limitation: raw cosine similarity over v2 is compressed, severely so within TransmonCross where the whole family spans 0.9928 to 1.0. The vectors are correct; a frozen whitening transform is still needed before v2 similarity is used for retrieval.
v0 and v1 files are unchanged.
Adds the 512-dimensional universal-geometry-v2 standard alongside static-embedding-v0 and universal-geometry-v1.
v2 consults no catalogue statistics: every coordinate is a physical measurement in micrometers, inverse micrometers, or farads per meter, accumulated onto frozen bin edges, so the encoder is a pure function of one GDS file and one design-option mapping. A contributor can encode their own layouts into this exact space without refitting anything.
This first table covers 13,683 GeneralizedCapNInterdigital designs. The remaining 6,379 cannot be encoded because SQuADDS_Layouts currently publishes 10,000 of the 16,379 q3d_cap GDS artifacts its manifest lists.
v0 and v1 files are unchanged.
