warnunresolved_ref
Proof rests essentially on external results: Williams's witness-circuit argument [Wil13], the JMV13 local reduction, and Zak's nondeterministic time hierarchy.
main_full_version.tex:183
warnunresolved_ref
Per-branch exponent uses the unlabeled cost estimate eq:three-costs from Section 3.5.
main_full_version.tex:1640
warnunresolved_ref
Counting each leaf relies on the unlabeled sparse-formula argument of Section 6.3 (eq:sparse-formula-cost) rather than a statement.
main_full_version.tex:3570
warnunresolved_ref
The proof environment only assembles the algorithm; the key recursion identity (eq:tensor-recursion-identity), mode expansion and mode-tuple count (eq:tensor-partition-count), and precision bound (eq:tensor-precision-bound) are argued in unlabeled text of D.4.4-D.4.6.
quantitative-reduction.tex:26
infostructure_uncertain
Skeleton records only the fixed-density proof (quantitative-reduction.tex:67-98); a second proof of the arbitrary-density bound is at quantitative-reduction.tex:317-361, and the combined single algorithm is described at 363-369.
main_full_version.tex:73

claim "Sparsify with sigma about 1/sqrt(log n)" (quantitative-reduction.tex:319-328) lies outside the recorded proof; a second proof or an appendix
main_full_version.tex:73
infostructure_uncertain
claim "Leaf counts via parity rows and contraction queries" (quantitative-reduction.tex:330-345) lies outside the recorded proof; a second proof or an appendix

claim "Arbitrary-density time and space accounting" (quantitative-reduction.tex:347-360) lies outside the recorded proof; a second proof or an appendix
main_full_version.tex:73
infoinferred_dep
critique: The enumeration bound 2Qr C_q(2D+1)^{2τn}2^{2n/r} in Prop 3.4 rests on eq:boolean-enumeration. Line 1980 obtains that bound via "Lemma  therefore computes the restricted sum". The proof at line 2033 cites eq:boolean-enumeration directly, but the DAG has no edge to the lemma.
main_full_version.tex:2013
infoinferred_dep
critique: The proof of Prop 3.4 (main_full_version.tex:2036-2037) says "The preceding Taylor identity and interpolation prove correctness". That identity, eq:full-taylor-sum, comes from "Apply Lemma  to [z^j]G_x" at line 1964. The edge is missing, which also leaves the lemma an orphan.
main_full_version.tex:2013
infoinferred_dep
critique: The statement of Prop 3.4 (line 2018) requires that the data "satisfy Definition ", and the proof uses that design throughout. The DAG has no edge.
main_full_version.tex:2013
infoinferred_dep
the statement's design satisfying Definition  is used; the proof relies on the layout's rows and denominators (the \ref in the statement text)
main_full_version.tex:3044
infoinferred_dep
"the rows have common denominator d_den=(R-1)!Q!" is the content of the row-coefficient lemma
main_full_version.tex:3044
infoinferred_dep
critique: Prop 5.3 takes d_H from eq:origin-residue (line 3049). That degree bound and the residue identity come from Lemma total-order: "Lemma  bounds the input degree ... By the same lemma, summing their values gives" (lines 3024-3035).
main_full_version.tex:3044
infoinferred_dep
critique: Lemma 6.2 opens "With P,D0P,D_0 and A(0)A^{(0)} from Lemma " (line 3447). Its proof uses the weight bound |supp v(x)| ≥ m/P from that lemma (line 3470). The DAG has no edge.
main_full_version.tex:3446
infoinferred_dep
Appendix  proves the lemma, including the disjointness (the branching rule partitions satisfying assignments of the parent)
main_full_version.tex:3543
infoinferred_dep
the appendix proving this lemma (app:sparsify) contains the marked-degree counting bound used in the occurrence bound B
main_full_version.tex:3543
infoinferred_dep
the appendix proving this lemma (app:sparsify) contains the insertion bound used for depth and node count
main_full_version.tex:3543
infostructure_uncertain
No proof environment; Appendix A (main_full_version.tex:3636-3884) proves it using Lemmas A.1-A.3 plus unlabeled tree-size and leaf-bound arguments.
main_full_version.tex:3543
infoinferred_dep
critique: Prop 6.4 counts each leaf "by the sparse-formula algorithm of Section 6.3" (line 3600). That algorithm is built on Lemma greedy-hashes ("The final count is #F by the greedy lemma", line 3526). The proof also says "initial checks, and additional rows are computed by the deterministic procedures above".
main_full_version.tex:3570
infostructure_uncertain
Used in prose (child edge bound at quantitative-contraction.tex:525) outside any proof environment; the skeleton records no ref edge to it.
