## Statement

The earlier mass-completion account claimed that every completion with at most two parameters was impossible.

## Caution

Withdrawing the universal claim does not rescue the exact single-chi class or make the fitted harmonic a derived replacement law.

## Primary source

Appendix O, §5, Remark 5.2: withdrawn universal parameter bound, PDF p.276: "The blanket “≤ 2-parameter completion is impossible” claim is therefore withdrawn; the honest statement is that surveyed one-parameter forms fail and no universal ≤ 2-parameter no-go is proved."
