Decision Record for Code Coverage Threshold in CI

Status

proposed

Context

The Unit Tests ADR established a 95%+ code coverage target. However, there was no automated enforcement — coverage was a goal, not a gate. Commits that dropped coverage below the target could still be merged.

Decision

GitHub workflow will fail every commit to the branch if coverage is less than the 95% threshold. The check runs as part of job-dotnet_test_coverage and validates line, branch, and method coverage against the threshold.

Consequences

No commit can be merged if it lowers coverage below 95%. This makes the coverage target from the Unit Tests ADR enforceable rather than aspirational.
