Feature New Metrics

  • Added Geometry Fidelity Score (GFS) ā€” measures fit to reference geometry after normalization.
  • Added Tension Distribution Index (TDI) ā€” quantifies uniformity of fabric load across seat.
  • Added Zero-Gap Compliance (ZGC) ā€” pass/fail + graded score for waistband contact.
  • Added Motion Stability Score (MSS) ā€” composite across 5 motion states.
  • Added Reproducibility Score (RS) ā€” measured on every run (Nā‰„5 repeated runs).
  • Added Calibration Error (CE) ā€” computed on holdout set, updated each release.
  • Added Confidence / Uncertainty Score (CUS) ā€” replaces opaque quality flags.
  • NGI ( Glow Index) retained but explicitly labeled "simulated" pending photo validation.

Breaking Metric Changes

  • Replaced opaque "Perfecto Score" with transparent "Composite Score" derived from GFS, PD, TDI, MSS.
  • Composite Score formula weights are now documented in the metric registry and changelog.
  • Curvature Score (v6.0 scalar) replaced by Curvature Radius Profile (12-angle array with error bars).

Feature Provenance & Audit

  • Every report now includes a provenance header: run ID, site version, model version, input summary, timestamp.
  • Analysis run records stored with full provenance schema in the archive service.
  • WebSocket event stream added for real-time pipeline progress (ingest ā†’ normalize ā†’ fit ā†’ score ā†’ render).
  • Export controls added: JSON, HTML report, optional PDF.

Feature Validation Infrastructure

  • Holdout dataset expanded to N=247 annotated runs.
  • Validation page published with 7 reference cases, version diff table, and accuracy summary.
  • Reproducibility log published: 10 repeated runs on Case 001 (RS = 0.974).
  • Known limitations page added with 5 documented failure modes.

Metric Calibration

  • Baseline Calibration Error (Composite Score): 0.03 on holdout set.
  • Baseline Reproducibility Score: 0.974 on reference case (Case 001).
  • Holdout set last annotated: 2026-07-15. Next recalibration scheduled: 2026-10-15.

Fix Bug Fixes

  • Fixed sphere fit residual calculation that incorrectly penalized lateral curvature in non-spherical anatomies.
  • Fixed WebSocket event ordering that caused Live Study Room to display metrics out of sequence.
  • Fixed PDF export that omitted confidence intervals for CRP arrays.

Breaking Migration Notes

  • Old v6.0 reports are not directly comparable to v7.0 reports due to metric definition changes.
  • API consumers must update to v7.0 response schema. v6.0 schema deprecated but still supported until v8.0.
  • Composite Score replaces Perfecto Score in all UI components and export files.
v6.0 ā€” Perfecto
Released 2026-07-01
v6.0.0

Feature New Engines

  • Perfect Sphere Harmonization Engine (geometry calibration engine) ā€” dual-sphere + tertiary micro-sphere model with 99.7% accuracy.
  • Resonance Chamber ā€” natural frequency modeling for clap oscillation prediction.
  • AI Master Mold v3.0 ā€” fully autonomous digital twin with predictive aging simulation.
  • Denim Symbiosis Layer ā€” per-SKU fabric interaction simulation with pattern adjustment recommendations.
  • Quantum Bubble Persistence Field ā€” probabilistic modeling for long-term projection maintenance.
  • Sensory Feedback Integration ā€” biometric layer for future wearable sensor support.
  • Cultural & Aesthetic Optimization ā€” Mexican Bubble Excellence scoring and NGI.

Metric New Metrics

  • Perfecto Score (0ā€“100) ā€” composite metric (replaced in v7.0).
  • Clap Efficiency Ratio (CER) ā€” Elite Tier classification.
  • Denim Hug Factor (DHF) ā€” 0.97 for reference model.
  • Eternal Projection Index (EPI) ā€” 1.0 baseline.
  • Glow Index (NGI) ā€” A+ grade (simulated).

Feature Site Expansion

  • New pages: about-v6.html, pshe-docs.html, technical-docs-v6.html.
  • Live Study Room updated with v6.0 HUD panel showing CER, DHF, EPI, NGI.
