5. Known Pre-existing Issues

Backend Coverage Below Threshold (Non-blocking)

Current: 83.5% (threshold: 85%) Root Cause: Pre-existing low-coverage packages, NOT from changes in this sprint.

Package	Coverage	Notes
internal/util	40.7%	Legacy utility code
pkg/dnsprovider/builtin	30.4%	DNS provider implementations
internal/config	58.6%	Configuration parsing

Recommendation: Track as separate improvement item in backlog.

Branch/Function Coverage

• Frontend branches: 78.32%
• Frontend functions: 79.46%

Note: Primary metrics (Statements: 85.07%, Lines: 85.73%) meet thresholds.
