Authored summary

Unresolved in this packet after the dated source check. Strongest checked result: Xu reduces attention to primes congruent to 1 modulo 24, parameterizes tame solution classes, and covers almost all tested tame primes in a stated finite range. The universal decomposition remains open. Exact unresolved remainder: Prove a positive three-unit-fraction decomposition for every integer n at least 2, or give an n and prove that no such decomposition exists.

The record cites sources for its explanation.
