Changelog

What changed, and when.

Engine releases, catalogue updates, web changes — in one feed. We publish every material change so a design's trust grade always traces back to a specific engine version.

  1. engineCLAUDE.md §112–§119

    v1.8.0+day3_audit — CAD enablers + HARD-FAIL gates

    Sprint v2.4 Day 3 batch: HARD-FAIL gates extracted to a shared callable (Pcu/Pcv ratio, T_hotspot, fsw extrapolation); solve_axisymmetric DC + AC, thermal_field_2d, FNO stub, system_capability detect. 1564 tests pass.

  2. dataWIRE-5

    YOLOv11n 24-class datasheet detector — production weights live

    Production ONNX shipped at mAP=0.9625. Engine resolver auto-prefers the production drop over the scaffold; zero engine code change required to flip.

  3. engine§97

    v1.8 Calc Sheet PDF Beauty Pass

    10 deterministic plot generators + 6 topology Jinja2 templates + 4-tuple metadata stamp (template/plot/engine/kb). Bit-for-bit reproducible — no LLM in the calc-sheet path.

  4. engine§78

    Sprint 6 WIRE — AI/ML stack wired into the production design path

    XGBoost pre-narrows the core pool (400k union, test_rmse 0.685), IsolationForest drift detector surfaces in DesignResult, topology rationale + trust narrator auto-attach.

  5. webDRIFT-1 Option A

    TS bridge engine removed — Pyodide is now the only compute path

    The in-browser TypeScript reimplementation drifted up to 41,868% vs Python and is gone. The calculator runs the canonical Python engine via Pyodide WASM — cannot drift by construction.
