Performance Reports (#1462)
- Multiple Levey-Jennings Charts: Supported multiple Levey-Jennings charts per mean cut-off in the performance report.
- Filtering and Rendering: Prevented template iterations over undefined values and enforced strict upper date boundaries when filtering multi-cut results.
⚙️ CI/CD & Infrastructure
GitHub Actions Workflows
- Self-Hosted Runner Restriction: Restricted self-hosted runners exclusively to development and testing environments.
