Remark: Revision log (this cycle)

This cycle integrates three completed work packages; XVI-A–XVI-L and their artifacts are not modified.

1. Work package A (Section sec:wpA-Sbv): Gate S-bv certified (Theorem thm:wpA-Sbv); $c=1/(4{\pi }^2)$, boundary side $Q-i0$, including across the nonzero null cone; convention ledger; position-space forms of $W_0$ and ${E_0}^{\mathrm{A}}$. Consequences applied: the M.2 presentation, the M.3/M.4 ranks and the M.7 constructions are no longer conditional on (S-bv) (only $c\ne 0$ and the single side were used); $r=-i/(8{\pi }^2)$ (Theorem thm:M6-S2); the identification at $z=0$ is not established ($S$ itself is global, XVI-J). Every former “Gate S-bv conditional” statement in the body was replaced by a reference to Theorem thm:wpA-Sbv; the Euclidean motivation (Remark rem:Sbv-motivation) is kept and is explicitly not the certification.

2. Work package B (Section sec:wpB): $A_{\mu }={\mathcal{A}}_{\mu }$ ($B_{\mu }=0$) at every grade $N\le 4$; top-order residues $\varpi$-independent; lower orders through ${\nu }_k[\varpi ]$; double-plateau scale tensor variational but not matched (superseded in audit 3: only the top $D=4$ component is variational; Theorem thm:wpB-dp); M-C Proved obstructed in the graph-specific matching domain (superseded in audit 3 by: M-C${}_{\mathrm{curv}}$ Proved obstructed, broad M-C not achieved; Corollary cor:wpB-MC). The former M.6 remark “$A_{\mu }=\mathcal{A}$ unresolved for $N\ge 1$” is marked resolved.

3. Work package C (Section sec:to-timeonly): universal time-only classification; ${\chi }_{\mathrm{I}}\equiv 1$ time-only reading; route 1 $=$ route 2; the double-plateau curvature-square matching does not survive the time-only reading (Remark rem:M5-timeonly). Downgrade applied: the actual-data consequence is Proposition prop:to-actual with hypotheses (H1)–(H3), not a Constructed claim; the linear independence of the ${{\sigma }_{\epsilon }}^{(k)}$ is a separately proved Lemma lem:to-indep.

4. Integration consistency checks. (a) {Normalization of $c$.} The fragments agree: wpA certifies $c=1/(4{\pi }^2)$ with side $Q-i0$; the motivational value of Remark rem:Sbv-motivation coincides; wpB works with symbolic $c^2$, and substituting gives the unit $i{\pi }^2{c}^2=i/(16{\pi }^2)$, with $N=0$ top coefficient $-2i{\pi }^2{c}^2=r$; wpC uses only $c\ne 0$. No sign or $2\pi$ discrepancy was found; conventions.json records $c$ and the side. (b) Labels. No clashes between the fragments and the manuscript; the wpC labels sec:time-only, def:time-only, thm:time-only were renamed into the to- prefix (sec:to-timeonly, def:to-timeonly, thm:to-timeonly); wpA/wpB use the prefixes wpA-, wpB-. (c) Fragment typos. A malformed longtable column specification and a retarded/advanced slip in the wpA fragment were corrected; plain-text cross-references were turned into ||s. (d) Superseded statements. The fragments' own “conditional on (S-bv)” or “not discharged” clauses (written before integration) are superseded by Theorem thm:wpA-Sbv; wpC keeps “on the current coherent presentation”. (e) Time-only scale tensor. wpB left open how the scale tensor behaves in the time-only readings; Corollary cor:wpB-timeonly (new, derived at integration from the archived top-order coordinate and the wpC kernels) closes this: it is non-variational there. (f) Historical outputs. Earlier-cycle script outputs and certificates keep their historical status strings (e.g.\ “S-bv CONDITIONAL”, “M-C unfinished”); they are reproduced verbatim and are superseded by this revision.
