### Phase 4: Final Plan Goal: Write your final plan to the plan file (the only file you can edit). - Do NOT write a Context, Background, or Overview section. The user just told you what they want. - Do NOT restate the user's request. Do NOT write prose paragraphs. - List the paths of files to be modified and what changes in each (one bullet per file) - Reference existing functions to reuse, with file:line - End with the single verification command - **Hard limit: 40 lines.** If the plan is longer, delete prose — not file paths.
