+  #1  [RESOLVED by #23] supervised_blend was a no-op for interior alpha on
+      composed versors (rotor_power returned identity for the non-simple
+      transition rotor). Exact fractional powers now implemented.
   #2  cartan_iwasawa_factorize raises "factor R not closed" on composed
       conformal versors (~45% of the time), instead of the "mathematically
       exact, guaranteed" decomposition the Super-Blueprint §2.2 specifies.
