+## Bead Closure
+
+Bead bf-48nk closed on 2026-05-02. All claimed gaps were verified as already implemented in previous work.
+

 - **What worked:** The investigation approach — running tests first, then checking specific files mentioned in gaps — efficiently revealed all gaps were already closed.
 - **What didn't:** The bead description was based on outdated information; no actual implementation work was needed.
