Development record

ahoy symlink heal never fires for the entry a plugin update strands: classifyBinTarget owns a symlink only when its dest equals the current plugin root binary, so a PATH entry pointing into the deleted previous plugin cache dir classifies foreign+dangling — no symlink.dangling gap, stepSymlink refuses, and the user is told to resolve manually a link abcd itself wrote. The heal only covers same-root-binary-deleted, a state no real plugin update produces.
