Binary waveform spectrum and correlation contract audit
Family 076: Real ultraflat Littlewood polynomials and unbounded binary merit factors. First application triage, 9 October 2026 Australia/Brisbane.
Problem and potential new use
Radar and communication R&D teams could benchmark binary sign sequences against new flatness targets and separate spectral flatness from autocorrelation objectives.
Applicability and commercial boundary
The selected formal statements are existential upper-maximum and finite-Lp flatness results, with no effective convergence rate or signing algorithm. They do not cover the latest uniform two-sided flatness headline.
Initial business decision
Research or conditional engineering only until an effective implementation and a recurring buyer problem are identified. No commercial demand or profitability is established. Where a direct product bridge is weak, the legitimate use is a research reference or evidence adapter, rather than a new standalone company.
Next verification action
Extract construction effectiveness and implement exact finite correlation diagnostics before any improved-waveform claim.
Evidence scope
The catalog statement was individually reviewed. Main-paper abstracts and available selected formal scopes were additionally inspected; explicit effectiveness passages were inspected for 076, 143 and 178. No independent proof verification was run.
