/bug-fix-implement

Architecture advisor and senior-engineer must implement bug fix following the investigation plan and track progress while implementing.

MANDATORY WORKFLOW:

1. Read the bug fix plan markdown file: $ARGUMENTS
2. Update the plan file status to "in-progress" before starting implementation
3. Follow the fix strategy step-by-step from the plan
4. CRITICAL: Update the plan file IMMEDIATELY AFTER EACH STEP with:
   • Step completion status (do not batch updates)
   • Any deviations from original plan
   • Unexpected findings or complications
   • Additional steps needed
5. Run tests to verify the fix works
6. Update the plan file with final status and test results

Use sequential thinking, context7 and microsoft-docs to solve the problem using latest documentation and best practices. IMPORTANT: The plan file MUST be kept up-to-date in real-time throughout the implementation process. Update after EACH action, not at the end, in case work is interrupted.
