v1 validation completed against this PR revision (refs/pr/2):

  • 20,062 unique rows and 512 dimensions
  • all values finite; vector norms range from 0.99999988 to 1.00000012
  • retrieval, cosine-nearest search, schema loading, and the 40-row parameter control map pass
  • downloaded parquet, schema, and control map match the deterministic release SHA-256 hashes
  • v0 remains the default 9,227-dimensional standard

After review, merge this dataset PR first. Then smoke-test v1 from main before merging SQuADDS code PR #67.

The original 512-dimensional v1.0 candidate has been rejected and replaced. It is not the proposed release: it blurred topology, compressed random-pair cosine similarities, and did not consistently outperform v0.

The current PR now contains the accepted universal-geometry-v1 schema v1.1 release:

  • 20,062 paired GeneralizedCapNInterdigital layouts
  • 1,024 dimensions: 32 geometry metrics, 768 full-spectrum shape descriptors, and 224 named-control channels
  • target-blind frequency selection from signed functional-material and signed-distance 96 by 96 rasters
  • 40-row auditable layout-control map
  • no simulation target is used as an embedding input or representation-selection feature

Paired acceptance benchmark at seed 1401:

Gate v0 v1.1 Requirement
exact finger topology 0.9600 0.9800 v1 >= v0
normalized parameter distance 2.4022 1.8621 v1 <= 90% of v0
signed-bitmap shape distance 0.2816 0.2993 v1 <= 110% of v0
mutual-capacitance neighbor MAE (fF) 0.7701 0.7047 v1 <= v0
random-pair cosine std. dev. 0.3509 0.2488 v1 >= 60% of v0

All five gates pass independently for seeds 1401 through 1405.

Public refs/pr/2 validation passed:

  • table shape: 20,062 x 19
  • embedding matrix: 20,062 x 1,024
  • all values finite and unit normalized; maximum norm error 1.2e-7
  • nearest-neighbor retrieval works
  • both 96 by 96 v1 shape channels reconstruct successfully
  • control map contains 40 entries

Verified SHA-256:

  • embedding parquet: 80abb1747aaf53141098c94ed9d2c75f61281dda77f021bcbb7733964d73ab72
  • schema: dcb90a925fdcd96d7760e098b2223f5745c0d6d9cda5d7be2f7bcf2ad3f819a3
  • control map: 5694744084ea25981c9064c97a8eb96082616d3ee53bb580fcbaa109635cff0d
  • release manifest: 99dd5d3407a86543d7fbb46318283873c1c6c26cff99fe25674b3f5002cc6105
