Documentation Freshness Audit overview

Audits documentation freshness and accuracy across all knowledge-management surfaces -- scanning document repositories for pages not updated within staleness thresholds, cross-referencing API documentation against current endpoint schemas for drift detection, validating runbook accuracy by comparing documented procedures against actual system configurations, reviewing onboarding documentation completeness against current toolchain and process, assessing code-comment accuracy in frequently changed modules, measuring documentation coverage ratios for public APIs and internal services, and triaging stale content for update, archive, or deletion. Produces documentation freshness scorecard and remediation backlog. Excludes documentation authoring.
