**Title 24 2025 run 1: annual simulation in progress (Standard design)**Native IESVE Tasks window during the first Title 24 2025 annual simulation (2026-10-24), with 'Generate Standard Model' completed. Run 1 is SUPERSEDED and its 'complies' result was NOT ACCEPTED (D-CX-24).

**Title 24 2025 navigator: annual simulation of Proposed and Standard designs (run 2)**Native IESVE 2026 Title 24 2025 navigator during the corrected run 2: Proposed and Standard Design selected for the annual simulation; 'Generate Title 24 Compliance Report' (PRF-01) is greyed out. Cropped screenshot, not an interactive model. The run's software 'complies' result was NOT ACCEPTED (D-CX-25, D-CX-28).Screenshot of the native tool (static image) · source: compliance-NATIVE-T24-RUN2-20261025/shots/sim-dlg.png (cropped)

**Title 24 battery step inputs (run 2): code-minimum battery**Native IESVE Title 24 battery model inputs: 37.522 kWh usable, 9.381 kW charge/discharge, loss factor 0.0566, 12-month availability schedule. Manufacturer-neutral code-minimum battery (third-party battery data used only for the efficiency basis). The step ran after the Results Summary, which shows battery 0.

**PV panel tool (blocked step)**Native IESVE free-standing PV panel dialog. Placing PV geometry could not be automated, so PV/SARA and the official compliance report remained BLOCKED.

Sanitised derivative of preserved evidence (compliance-* evidence folders, branch feat/compliance-engine). Nothing was re-simulated for this pack; IESVE was not started. Screenshots are cropped and reviewed; plots and the report contain only values read from the evidence. Not a compliance document. · Pack sf-office-compliance-r2 (built 2026-10-25); every file is checked against its SHA-256 before it is shown.
