Then, generate a table that ranks the necessary fixes by their impact and effort. Lastly, give me the actual code corrections in batches, showing the original code, the updated code, how much time it will save, and how to test it before going live.

After that, I need a matrix comparing the risk versus impact for the proposed solutions. Finally, provide the code fixes grouped by risk level, making sure to include the exact file changes, before and after code blocks, expected metric changes, and a checklist to verify the deployment. Make sure to use your standard bracketed labels and severity emojis. | pass→pass | 19,975 | 17,351 | -13% | 1 | 1 | 0% | 3,980 | 10,824 | +172% | 0 | 0 | — |
