Internal reconstruction is not characteristic composition

The supplied XIV-H release records an unresolved internal transition-amplitude requirement at H2. XIV-I subsequently constructs its specified internal retarded-pole amplitude module at I2, but leaves the complete joint characteristic operator map unresolved at I3 CheungXIVH (thm:H2) CheungXIVI (thm:I2, thm:I3).

The supplied XIV-J excerpts add reconstruction descent and a supported-sector reference for $K_6+K_8+K_9$ away from the characteristic locus. They do not construct the full map for the six-branch sum on tests meeting that locus CheungXIVJ (thm:reference, thm:J2). Neither a normal-jet formula away from a locus nor a conditional coefficient-extension interface supplies an extension across it.

The elementary descent condition can be stated without importing any of those analytic constructions.
