Status: Candidate \mC. 000315 | 000316 | \par\smallskip\noindent\textbf{Executed update (2026-08-30, review wave~7): T1/T2 proved, T3 000317 | Michalakis--Zwolak cited-verified, dynamical [N], $1/192$ and BDL boxed 000318 | (\veri{v1007\_\allowbreak det16\_\allowbreak stability\_\allowbreak battery.py}; 000319 | the candidate stays \mC).} 000320 | The $12$-page memorandum 000321 | \texttt{articles/2026-08-30/\allowbreak det16\_\allowbreak mirror\_\allowbreak gap\_\allowbreak theorem\_\allowbreak en.tex} 000322 | proves T1/T2 and verifies every Michalakis--Zwolak hypothesis (Local-TQO, $t_*>0$, perturbed 000323 | gap at least $1/2$). Ordinary hopping is \emph{not} block-diagonal 000324 | ($\lVert(1-P)KP\rVert\neq0$), so $t_{0,\mathrm{count}}=1/192$ remains the uncertified counting 000325 | threshold, not a theorem. Dynamical $\mathbb Z_2/\mathbb Z_4$ links on the four-mode analogue 000326 | are uniquely gapped on the compressed grid (full-probe minimum $0.728854416$ pinned); 000327 | second-order Schrieffer--Wolff is $1-\alpha t^2+O(t^4)$ with $c_{\mathrm{geo}}/L$ bounded. 000328 | BDL supplies a ground-energy truncation error with unspecified constants, not a volume-uniform 000329 | gap remainder --- boxed. Display marker stays \mC. 000330 | 000331 | \par\smallskip\noindent\textbf{Executed update (2026-08-31, Monday-morning harvest; 000332 | \veri{v1016\_\allowbreak state\_\allowbreak gap\_\allowbreak batteries.py}; 000333 | the candidate stays \mC).} 000334 | Fröhlich--Pizzo hypotheses cited-verified for $\mathbb Z_2/\mathbb Z_4$ DET open chains: 000335 | volume-uniform spectral gap $\ge\Delta/2$ in the parametric window $\tau_{\mathrm{FP}}$ 000336 | ($a=0.0233$, $a/16=0.00146$). The dynamical-link leg is closed at that finite-group 000337 | level. Remaining: rotor links, wall mixing, $3{+}1$D placement. Display marker stays \mC. 000338 | 000339 | \par\smallskip\noindent\textbf{Executed update (2026-09-05, round-3 integration): 000340 | derivative-filtered wall block 000341 | (\texttt{CHIRAL4D.MIRROR.DFILTER.BLOCK.01}; 000342 | \veri{v1023\_\allowbreak derivative\_\allowbreak filtered\_\allowbreak wall.py}; no parent 000343 | marker move).} 000344 | For 000345 | \[ 000346 | H_{\rm df}=\Delta b^\dagger b+ 000347 | \lambda\bigl(b+gD_{\rm GW}p\bigr)^\dagger 000348 | \bigl(b+gD_{\rm GW}p\bigr) 000349 | \] 000350 | each singular-value sector is the exact $2{\times}2$ block with determinant 000351 | $\lambda g^2\Delta s^2$. It preserves $\ker D_{\rm GW}$ on the physical summand, 000352 | the adiabatically mirror-continuated high branch is at least $\Delta+\lambda$, and 000353 | \( 000354 | \mu_-(s)=\lambda g^2\Delta(\Delta+\lambda)^{-1}s^2+O(s^4). 000355 | \) 000356 | The finite covariance and SVD-reduction defects are 000357 | $2.408{\times}10^{-15}$ and $1.776{\times}10^{-15}$. This is only a finite 000358 | quasi-free block lemma. For $s\ne0$ the bare $b$ subspace is not invariant and has 000359 | low-band weight, so no bare-mirror response gap is proved; the low branch has 000360 | $z=2$, not a Weyl cone. No canonical DET16/DET32 realization, interacting parent, 000361 | admissibility/quasilocality theorem, measure/anomaly/index control, universality or 000362 | $3{+}1$D continuum limit follows. The derivative-filtered witness therefore does 000363 | not upgrade \texttt{CHIRAL4D.MIRROR.DET16.01}~\mC, 000364 | \texttt{CHIRAL4D.NOMIRROR.01}~\mO, T4, or TOE. 000365 | 000366 | % =====================================================================
