TransmonCross and CapNInterdigitalTee are regenerated so that every family now shares one simulation-domain convention:
* a fixed 169 um per-side ground margin, the pooled median of the reference GeneralizedCapNInterdigital sweep, replacing the earlier proportional rule. Padding in the reference sweep is essentially uncorrelated with conductor width (Pearson -0.10), so a proportional rule placed the ground plane furthest from the largest device, which is the opposite of what an absolutely anchored coupling spectrum needs;
* the native subtractive etch retained rather than discarded;
* ordered port markers on layers 2 and 3 that bridge each terminal to the ground boundary, matching GeneralizedCapNInterdigital.
design_id and source_id are unchanged and set-identical to the previous release, so every existing join and published study still resolves. layout_id is a content hash and necessarily changes for the 2828 regenerated files. GeneralizedCapNInterdigital and CavityClawRouteMeander …
Unify TransmonCross and CapNInterdigitalTee to the GeneralizedCapNInterdigital layer convention
Regenerates 2,828 GDS files directly from Qiskit Metal qgeometry so three of the four families share one convention: a ground plane sized to about 5.8x the conductor extent and centred on it, the etch expressed as a single hole in that plane rather than layer 1/11, and two ordered lumped ports bridging the moat from each terminal to ground.
Previously CapNInterdigitalTee omitted positive CPW path, leaving its conductor at roughly half its true area, and TransmonCross carried no ground plane at all.
BREAKING: layout_id is a content hash and changed for all 2,827 affected identities. design_id and source_id are unchanged and remain the stable join keys. GeneralizedCapNInterdigital and CavityClawRouteMeander rows are untouched. The previous geometry stays available by pinning the prior revision.
CavityClawRouteMeander keeps the earlier convention; layer-semantics-v1.json schema 1.3.0 declares this per family.
