type:audit type:review

Formal, evidence-based software engineering audit producing a scored, gated release verdict. Use when asked for a "full audit", "production audit", "release audit", "formal audit", "audit report with a verdict", "is this safe to ship", customer-assurance review, or a re-audit against a prior report. Runs the Universal Software Engineering Audit Specification v2.2 end to end: intake, control selection, evidence ledger, deterministic scoring, release gates, machine-readable artifacts. NOT for quick cleanup passes or refactoring - use a lighter review flow for those.
