# 1-orphaned Pins the **stale / orphaned** taxonomy edge → `delete-range` exact-edit kind → derived `confirm` tier (delete-range is destructive + irreversible). **Scanner signal exercised:** `broken_reference`. `docs/orphan.md` links to `./gone.md`, which is absent from `input/`, so the scanner emits exactly one `broken_reference` signal on `docs/orphan.md`. The doc is otherwise unreferenced and describes a dead workflow — the coherent justification for *orphaned* rather than a link-repair (`replace-text`): there is no live target to repair to, so the block is deleted.
