QTT Carrier-Deletion Finite-Window and Timing-Access Blind Test Extension

Erase the apparent carrier. Recover the qubit from its halo. Then ask a different clock. This preregistration separates an ordinary quantum-memory qualification from a distinct timing test. Test A evolves a logical qubit through a frozen local channel, physically resets its original carrier, and asks whether a finite surrounding window can recover it. Test B asks whether that independently reconstructed channel fidelity controls a separate timing-covariance frontier. Test A: where is the recoverable channel? \[ \mathcal R_i(\omega)=|0\rangle\!\langle0|_i\otimes\operatorname{Tr}_i\omega, \] \[ Q_{\rm del}=2F_{\rm avg}(\mathcal N_{\rm del},\operatorname{id})-1, \qquad \boxed{F_e^{\rm del}=\frac{1+3Q_{\rm del}}4.} \] Target-only and every smaller halo subwindow remain optimized counterfactuals. A physical reset, sham reset, hidden-record injection, boundary ladder, and complete terminal record are required before the recovery layer qualifies. Test B: does the memory verifier intertwine with an independent timing projector? \[ \boxed{W^\dagger M_eW=P_{\rm align}}, \qquad \eta_T=\operatorname{Tr}(\rho P_{\rm align}), \] \[ \mathcal U_T^\star =\inf 2\sqrt{\det\Sigma_{T\Omega}}. \] On the certified canonical branch, the sealed QTT target is \[ \boxed{ \eta_T=F_e^{\rm del}, \qquad \mathcal U_T^\star=1-F_e^{\rm del}. } \] No complement coefficient is fitted. Five fidelity corridors, a radius/depth ladder, one-third untouched holdouts, topology twins, full covariance, global five-sigma decisions, at least 95% planned power, and transfer to a second record technology are frozen before data. The external computation is a feasibility anchor, not the timing target An, Cao, and Cui report carrier-deletion recovery in a local kicked-Ising memory. Their result qualifies the plausibility of Test A. Their reported \(Q=0.516\) is explicitly forbidden from constructing Test B. The public source archive lacks the exact arrays and scripts, so exact replication remains pending. Five terminal outcomes INELIGIBLE_NO_THEORY_VERDICT REGISTERED_QTT_CONSEQUENCE_FALSIFIED QTT_CANDIDATE QUALIFIED_OTHER_OR_CROSS_CHANNEL_ANOMALY AMBIGUOUS_OR_UNDERPOWERED Any failed eligibility gate terminates without a theory verdict. A positive result requires the full multirung shape, not one selected point. An off-target anomaly is preserved rather than discarded or used as a post-hoc rescue.
