We propose a physics-anchored row-scale $\\pm 400$ Vdc architecture that makes Computational Continuity a structural property. DRUs supply fast energy via controlled droop; SSTs regulate average power with bounded ramps and no reverse power flow and no high-frequency export at the PCC; import is subjected to a bounded dP/dt envelope; film capacitance and clamps absorb the first edge. The contract is explicit: $\\pm 1\\%$ steady-band, $\\leq 2\\%$ transient deviation, $\\leq 3$ ms recovery, $\\geq 45^{\\circ}$ margin, reserve floors intact, yields spine and lowest branches. Recharge is valley-following (admitted only below Avg with MW headroom; $\\leq 5$ kW/s per row ramps). Protection is time-graded (branch $μ$s, row ms, MW seconds). Scaling preserves invariants from row to pod/hall/campus without retuning. Conformance is by waveform evidence (microsecond branch clears, $2\\%/50$ ms holds, FLISR with no reverse power flow and no high-frequency export at the PCC). The result is not tuning but a contract for continuity.","short_abstract":"AI training creates synchronized, step-dominant surges with millisecond edges that destabilize constant-power loads (Choukse et al., 2025; arXiv:2508.14318).
