# UtiliVera Duplicates 0.9.0 engine-test evidence - Generated UTC: `2026-08-15T12:55:35.6594050+00:00` - Frozen EXE: 353,792 bytes - File/Product version: `0.9.0.0` - Frozen EXE SHA-256: `5F59977C69A25CCCB9569D1ED3F4F2D8043E2336CCFCD4C14933A623C754D727` - Command: `powershell -NoProfile -ExecutionPolicy Bypass -File run-tests.ps1` - Result: **73/73 PASS**, exit code 0 ## Evidence boundary The suite recompiles the current audited engine and test sources listed below. It does not claim to introspect compiled source from the EXE. Frozen EXE command-line behavior and installed-payload identity are separately exercised by `installer-test-evidence-0.9.0.json`; the independent round-eight report records the clean-copy 73/73 run and frozen CLI checks for this exact EXE hash. ##
