Development record

The pinned PATH symlink written by ahoy install targets pluginBinaryPath(pluginRoot) — a commit-stamped plugin cache directory. Every plugin update orphans that directory and the harness garbage-collects it ~14 days after .orphaned_at, so for a marketplace user the ~/.local/bin/abcd symlink silently dangles within two weeks of every update. The heal path (symlink.dangling gap + re-running ahoy install) exists but nothing triggers it automatically. Fix follows the persistent-data-dir relocation: point the pinned symlink at the data-dir binary, whose path is stable across updates.
