NexusOS Mobile SDK — Native iOS and Android Spectral Computing

The NexusOS Mobile SDK brings physics-native computing to iOS and Android. Both SDKs implement the full CE encoding stack natively — no server round-trip required for wavelength calculation, Ψ channel derivation, or spectral address generation.

iOS SDK (Swift)

Native wasciiEncode(_ text: String) -> SpectralResult — offline CE encoding using CE_TABLE[charCode % 128]
Ψ channel derivation: wavelength → WDM index, OAM mode, polarisation
WNSP URI generation: wnsp://Ψ(wdm,oam,pol)/path
Physics fee calculator: E=hf given user's spectral address

Android SDK (Kotlin)

Same API surface as iOS — wasciiEncode(text: String): SpectralResult
Bit-identical CE encoding output to npm and pip packages
Offline-capable: all physics calculations run on-device
Ψ channel addressing and WNSP URI construction

Both SDKs are AGPL-3.0. When photonic ASICs arrive (~2032), the SDK wavelength calculations map directly to hardware lane selections with no logic change required.
