Mixing Angles as Redescription Coordinates

This paper shows that if mixing angles are required to remain admissibly consistent across locally valid redescriptions, then they cannot function as intrinsic physical parameters without loss of standing. Treating mixing angles as fixed or dynamically significant quantities leads to incompatibilities when transitioning between admissible representational contexts, as their numerical values depend on the choice of description. Interpreting mixing angles instead as coordinates of redescription preserves compatibility by restricting their role to representational bookkeeping rather than invariant structure. The result is conditional and eliminative. It does not deny the usefulness of mixing angles within specific descriptive schemes, nor does it propose a mechanism for their emergence or evolution. Instead, it excludes interpretations in which mixing angles are treated as standing-preserving invariants across admissible contexts. Mixing angles are therefore constrained to function as redescription coordinates whenever admissible boundary consistency is retained.
