4 · Methodology (iz-1)

iz-1 is a 2-layer browser-resident MLP with WebGPU-accelerated LoRA-shaped weights, trained on TR-MRV-Bench v0 (59 Turkish CBAM-scope facilities; 21 audit-grade Scope 1 labels with operator-PDF citations). Inputs: nameplate capacity, geo-coordinates, sector + steel route one-hot, Climate-TRACE-derived capacity factor and activity, operator-disclosed capacity factor (non-leaky in LODO), and Sentinel-5P NO₂ activity proxy. Evaluation: stratified leave-one-disclosure-out with 5 outer × 3 inner = 15 seeds per held-out facility. Headline: median 87% reduction in log-MAE vs. EU CBAM default; closed-form formula (capacity × route-EF × cf) reaches the same headline within statistical noise.

5 · Verifier checklist

1. ☐ Confirm Scope 1 line item in the cited source matches the value above (tCO₂ basis; not CO₂-equivalent if different).
2. ☐ Verify operator's verification statement (ISO 14064-1 / TSRS / financial audit) attached to the source.
3. ☐ Cross-check capacity against latest published cement / steel / aluminum / fertilizer association registry.
4. ☐ If using iz-1 prediction as input to CBAM Article 4(2) actual-emission declaration: the prediction is a model output, not a measurement. Verifier must independently support the underlying activity data.
5. ☐ Confirm the conformal prediction interval covers the operator's claimed Scope 1.
