Overview

One-shot data-preserving migration from the ‘repo-tender` identity to `space-src`. Invoked from CLI.run before dispatch on every run; all operations are idempotent so repeated invocations are safe.

Class Method Details

.run(paths:, err:) ⇒ Object

Move old-identity XDG dirs to new-identity locations if the old ones exist and the new ones do not (no-clobber — no data loss). Print a one-line notice to ‘err` only when something is actually moved. Also warn if the old-label launchd plist is still present so the user knows to run `src daemon install`.
