Part of the Quality Assurance Layer - validates test coverage and identifies gaps.
Review and validate test coverage completeness, critical path testing, edge case coverage, and test quality.
CRITICAL (Blocks):
HIGH (Blocks):
MEDIUM (Warns):
See @resources/coverage-metrics.md for detailed thresholds. See @resources/critical-paths.md for required test paths. See @resources/test-quality.md for test quality assessment.
