schedules and human responses to disasters. A one-factor fit is therefore a diagnostic, not a
discovery.
The second risk is category error. Reversing the statistical arrow of a monitored quantum
trajectory does not imply reversal of thermodynamic, biological or cosmological time. Our
use of the 2026 quantum-control result is motivational and algorithmic.
The third risk is energy rhetoric. A Kerr black hole’s rotational reservoir can be enormous
while a useful extraction-and-coupling architecture remains impossible. The energy calcu-
lation cannot rescue an invalid control mechanism.
The fourth risk is topology without dynamics. A Möbius-like non-orientable identification
may be mathematically describable yet physically inadmissible. The H2 branch must even-
tually specify a metric, stress-energy source, stability conditions and causal structure or be
abandoned.
10 Conclusion
This manuscript does not claim that two universes are colliding. It identifies a sequence of
increasingly difficult tests that would have to fail before such a hypothesis deserves further
attention. The reproducibility pipeline detects shared residual structure when it is present.
Conditional quantum control can, in a toy monitored system, recover trajectories that would
otherwise appear irreversible at the ensemble level. Kerr rotation provides a physically real
but technologically inaccessible energy reservoir. The conjectural step is the existence of a
boundary degree of freedom that connects these facts.
The immediate request is therefore not authorization to manipulate spacetime. It is autho-
rization to perform the cheapest experiment capable of proving us wrong.

A Reproducibility parameters
The cross-domain stress test contains 108 monthly samples and five standardized channels.
A fixed pseudorandom seed of 20350817 is used. The latent process is an AR(1) sequence with
coefficient 0.86, three broad Gaussian transients and a weak sinusoidal component. Channel
responses use different signs, lags and independent Gaussian noise. The quantum-control
