<objective> Edit the phase list in ROADMAP.md safely. `add` and `edit` are near-trivial markdown changes; `insert` and `remove` are not - they shift phase numbers, and a phase number lives in four places whose live references have to follow or the project's references rot. Shipped requirement rows are history: insert and remove leave them as written. This skill keeps the live references consistent. </objective>

<process> Route on `$ARGUMENTS` (add | insert N | remove N | edit N) and run the phase workflow. For insert/remove, do the full renumber-and-repair pass - never edit ROADMAP alone. Commit the change atomically (protected-branch guard applies); never leave phase dirs and live references out of sync, and never hand-shift a requirement row the seam left as written. </process>
