Move one file or folder out of the way without losing it: it goes to `archive/<year>-<month>-<day>/` inside your personal workspace, keeping its relative path underneath, and a folder moves whole. Nothing is ever deleted or overwritten — a name already taken at the destination gets a numeric suffix. Only your own workspace is reachable: `shared/`, `uploads/`, `generated/`, `.compaction/`, `.git/` and the archive itself are refused, and so is `MEMORY.md`, which is corrected rather than archived. `path` is required and names one item.
