Jul 1, 2025July 2025 (cceh/FormierungEuropas): No user-facing features delivered. The month focused on repository hygiene and clarity of commit history. A key issue identified was two commits labeled 'Updated' that contained no diffs and did not describe any user-facing feature or bug fix, highlighting a gap in commit messages and change traceability. This finding will drive process improvements in commit discipline. Planned actions include establishing descriptive commit message guidelines and preparing a lightweight plan to monitor commit quality in future sprints. Impact: improves release traceability, auditability, and maintainability, reducing risk from vague changes.
