 Version 1.0.0 is defined in `config/audit_scoring.json` as `native-audit-score-v1`. Changing weights requires a reviewed definition-version change, rather than silently moving the denominator. Exact profile and corpus fingerprints let a reviewer identify what was assessed. The profile hash must match before and after planning and the plan's returned hash; observed source changes abort reporting. Hashes bind recorded content, not the trustworthiness of a malicious evidence author. Letter grades and a combined security score are deliberately not defined by this first implementation of issue #10.
 
 Tests cover exact/minimum mask truth tables, optional/role omissions, unknown and empty denominators, severity weights, exclusions/unique IDs, evidence-context preservation, source changes, output collisions, HTML encoding and public command isolation. Windows Server 2022/2025 PowerShell 5.1/7 tests read real policy and verify that native masks/precedence remain unchanged. Synthetic Ready rows test arithmetic only. No Windows 11/DC/AD CS deployment or backend query evidence is claimed by those tests.

 Audit scoring uses weighted rule metadata and reports numerator, denominator, exclusions, and conditional evidence. A score summarizes reviewed eligibility states; it does not prove event generation, forwarding, or detection.
