Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: resolution/device profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
