+# CDSL Bridge: Hexagonal Nut
+
+- Use for a hex body with a centered internal threaded-bore intent.
+- Invariants: across-flats, thickness, centered bore, and functional lead-in chamfers.
+- Plan: polygon/hex `extrude_add_blind` -> centered bore or `hole_wizard` -> thread audit -> finishing when selectors are valid.
+- Preserve across-flats separately from thread/bore diameter. Do not create a mating bolt.
+- Current runtime does not create helical threads; represent the bore and record `approximated: thread_geometry_omitted`.
