🔐 Security Questionnaire Answer Drift Auditor

Security Questionnaire Answer Drift Auditor creates a local second-pass review between an approved answer library and an incoming questionnaire. The deterministic helper checks mapping, approval state, evidence age, product and deployment scope, dropped references, numeric changes, negation changes, absolute claims, wording drift, and missing owners. It returns findings, a lineage ledger, a JSON approval gate, and a review memo without generating new security claims, connecting to a platform, or submitting an answer.
