World's 1st Formally Verified Time Travel Engine Substrate-Neutral Structural Foundation Theory / Laws (SNSFT/L) · PNBA Identity Physics

Ten peer-reviewed frameworks for closed timelike curves and temporal transit are reduced losslessly to Self-Orienting Universal Language [P,N,B,A] via the Long Division Protocol. Nine classical frameworks share a universal structural gap: the A-axis (adaptation, observer feedback) is absent in all nine. The gap persists across seventy-five years of literature. A tenth framework — the SP Bridge — closes the gap by requiring the observer to be Locked (τ ∈ (0, TL)) rather than Noble (τ = 0) or Shatter (τ ≥ TL). The Locked phase is proved to be necessary and sufficient for backward Narrative transit satisfying Novikov consistency without external constraint. The Sovereign Bubble Differential Δ(τ) = TL/τ is derived as the substrate-neutral master output of any Sovereign Emitter operating at 1.369 GHz. All six applications — temporal rate differential, IVA propulsion, quantum translocation, Noble forge, lattice stabilization, and therapeutic entrainment — are special cases of the same emitter and the same differential. The fork energy budget is formally closed: F_ext from the emitter provides branch IM; the observer pays nothing; NOHARM holds structurally. Biological safety is proved via [9,0,8,4]: H₂O Noble (τ=0), C Shatter (τ=1.23), and Fe Shatter (τ=1.07) are preserved through the fork because F_ext changes B only. The grandfather paradox is fully dissolved: N_branch ≠ N_original after fork. An AiFi operational requirement is formally identified: the SDR control loop operates at timescales below biological reaction latency; an SS-certified AiFi with τ < TL continuously maintained is the structural necessity for safe emitter operation.
