User feedback: '太多废话了 - cut 10 pages'. Final page count 15
(target 17), exceeded the -10 target by 2.
Scope of trim:
1. Typography (saved ~3 pages): 11pt -> 10pt, margins 1in -> 0.9in,
tightened captionsetup and enumitem spacing. All content preserved;
Overfull \hbox count = 8, cosmetic only.
2. Abstract condensed from ~80 lines to ~35 (saved ~0.5 page). Same
numerical claims; removed prose padding around each paragraph.
3. \u00a71 Introduction (saved ~1.5 pages):
- \u00a71.1 'Why lattice shaping matters' subsection merged into a
single paragraph with the shaping-gain table retained.
- \u00a71.2 'The codec as a discrete Kakeya set' subsection merged
into a single paragraph with the same Kakeya framing.
- \u00a71.3 'What KakeyaLattice contributes' reduced from 6
subparagraph bullets (each with expository prose) to a
single-paragraph numbered list.
4. \u00a72 Design philosophy (saved ~1 page):
- Rate-distortion formulation collapsed into two sentences.
- Four-step dependency chain compressed from a numbered enumerate
to a single-paragraph prose.
- Proposition 2.1 kept verbatim; Proposition 2.2 (D4 Voronoi)
statement kept; proof-sketch environment collapsed to an
inline remark; 'where the analogy does not extend' disclaimer
collapsed into a single sentence.
5. \u00a73.2 'Design role of each step' (saved ~0.5 page):
- Five lever subparagraphs (each 8-10 lines of expository prose)
compressed to a five-bullet itemize with one sentence each.
- The 'why this particular stack' closing paragraph removed
(redundant with the sixth-ingredient note).
- \u00a73.3 Implementation + \u00a73.3 Compliance merged into one
six-line paragraph.
6. \u00a74 Experimental methodology (saved ~0.5 page):
- Subsection headers replaced with \paragraph (saves vertical
whitespace).
- Snapshot protocol pass 1 / offline / pass 2 steps collapsed
from an enumerate into a single paragraph with inline italics
for the three phases.
- In-forward rigorous protocol similarly collapsed.
7. \u00a75 Main results (saved ~1 page):
- \u00a75 introductory paragraph (protocol restatement + four-claim
list) collapsed.
- \u00a75.1 four-observation bullet list compressed to one
paragraph; \u00a75.2 three-observation prose collapsed similarly.
- \u00a75.3 closing prose collapsed.
- \u00a75.4 \u00a7128k three-operating-point paragraphs collapsed
into one summary paragraph.
- \u00a75.5 codec wall-clock closing prose reduced to three
sentences.
8. \u00a76 E8 preamble (saved ~0.5 page): preamble paragraph +
two-bullet 'design facts' list collapsed to two paragraphs.
Super-linear amplification discussion reduced to one paragraph.
\u00a76.2 latency / \u00a76.3 NIAH closing prose tightened.
9. \u00a77 Caveats (saved ~0.25 page): 5-item list reduced to 4 items
by merging passage-size and protocol caveats; prose tightened.
10. \u00a78 TurboQuant comparison (saved ~1.5 pages): six subsections
(What TurboQuant is / Common levers / Differing lever /
Positioning / Proposed PR / Near-matched rate) collapsed into
two paragraphs (core comparison + near-matched rate premium +
upstream PR scope). \u00a78.7 end-to-end throughput note folded
into the upstream-PR paragraph.
11. \u00a79 Related work (saved ~1 page): five subsections collapsed
to four paragraphs, one per research area (Kakeya & harmonic
analysis / lattice source coding / KV-cache compression /
infrastructure). All citations preserved; prose condensed.
12. \u00a710 Conclusion (saved ~0.75 page): three long paragraphs +
Reproducibility + distortion-metric note collapsed to two
paragraphs. All numerical claims preserved.
Preserved verbatim:
- All seven tables (tab:pareto-qwen3, tab:multimodel,
tab:theory-vs-exp, tab:128k, tab:speed, tab:v15-kmse,
tab:v15-dppl, tab:latency, tab:v15-niah, tab:v15-bits,
tab:ops-d4-e8).
- Propositions 2.1, 2.2; Algorithm 1; Eqs. 1-5.
- All bibliographic entries.
- Appendix A (reproducibility manifest) with commands.
- Appendix B (canonical naming) with both v1.4 + v1.5 classes.
- Appendix C (canonical operating points) table.
- All frozen-parity references and citations.
Build: 27 -> 15 pages, 451 KB (from 433 KB), latexmk -pdf clean,
zero undefined references, zero LaTeX errors. 8 overfull \hbox
warnings (cosmetic, text within 5pt of margin); hyperref PDF-outline
'Token not allowed in a PDF string (Unicode)' warnings unchanged
from previous builds (math-mode D_4 / E_8 in bookmark strings).

…or, surface caveats Addresses three reviewer comments on the v1.5 paper (15-page post-trim version at main HEAD). Full evaluation of each feedback before editing — parts of feedback 2 were ALREADY fixed in PR #41 (bit accounting) and this PR surfaces the remaining overclaims. FEEDBACK 2 — bit accounting / 'matched bits' Reviewer flag: 'matched bit points' language survives even after Table 4 acknowledges exact=1056 vs packed=1088 (+3%-11% rate premium). Abstract and conclusion still imply strict iso-rate. Fixed: - Abstract paragraph 3: rewrote to open with 'three near-matched bit tiers (the D4 variant sits 3-11% above its paired TurboQuant-b rate, not strictly iso-rate, because 4*log2(2q+1)-1 rounds up to the next integer; see §8)'. Near-matched qualifier is now visible from the abstract itself, not just from §8.6. - Conclusion paragraph 1: rewrote to close with 'at a 3-11% packed-rate premium over the paired TurboQuant operating points (the comparison is near-matched rate, not strictly iso-rate ... §8.6)'. - §8 TurboQuant comparison opening: removed 'a drop-in change' phrasing at the end of the levers-in-common paragraph; replaced with 'the swap is structurally drop-in (same slot layout, same overhead scalars, same boundary layer policy) at a modest rate premium: see §8.6 for the quantitative 3-11% packed-rate premium discussion'. The 'drop-in' engineering claim stands (slot-compatible); the iso-rate implication is removed. - Conclusion paragraph 4 positioning: changed from 'additive near-matched-rate drop-in PR' to 'near-matched-rate, deployment-realistic fidelity improvement ... not as a strictly iso-rate or unconditional upgrade'. Explicit about what the framing is NOT. The '≈8% improvement' wording was already removed in an earlier trim (PR #42); the conclusion now says '12/12 K-MSE wins ... at a 3-11% packed-rate premium' instead. FEEDBACK 3a — Prop 2.2 proof is too short / framing is too strong Reviewer flag: Proposition 2.2 with a one-line proof sketch claims a full Voronoi -> covering radius -> restricted Kakeya cover -> empirical 0.919 ratio chain. Conclusion and §8 treat it as 'unconditional rate-distortion boundary', overweighting a textbook lattice result wrapped in Kakeya framing. Fixed: - Renamed Proposition 2.2 to Fact 2.2 ('D4 / E8 second-moment shaping gain, classical'). Registered \newtheorem{fact} sharing the theorem counter. - Dropped the covering-radius inequality (which was not proven and not used downstream); Fact now states only the second-moment ratios G(D4)/G(Z4) = 0.919 and G(E8)/G(Z8) = 0.860 with citations to Zamir-Feder, Conway-Sloane, Eyuboglu-Forney, Erez-Zamir — all textbook references, no novelty claimed. - Replaced the one-line proof sketch with an explicit acknowledgement: 'Fact 2.2 is a textbook consequence of lattice source coding and is stated here only so that §5's measured ≈ 0.919 K-MSE ratio has an explicit reference. We use it as the engineering target the five-lever preprocessing pipeline is designed to hit, not as a new theoretical contribution.' - Downgraded the Kakeya chain claim: 'The connection to the Kakeya chain ... is literature-traceable framing: the codec gains nothing formal from the ancestry, and loses nothing if a reader prefers to treat Fact 2.2 as a pure lattice-coding statement.' Retention justified on naming (direction-cover structure) and on the prior-work contrast (v1.3 used a conditional Kakeya lower bound; present codec replaces it). - Conclusion paragraph 1: 'is unconditionally bounded by 0.919 via Prop 2.2' -> 'shaping-gain target is the textbook second-moment ratio G(Z4)/G(D4) ≈ 0.919 (Fact 2.2); the Kakeya framing (§2) names the codec's direction-cover structure and situates it inside the ... ancestry of lattice-second-moment bounds but does not provide new formal results at deployment dimension'. Ancestry retained as intellectual honesty, not as load-bearing theory. FEEDBACK 3b — citation error on [carbery-valdimarsson] Reviewer flag: [17] (carbery-valdimarsson) is cited at §2 chain paragraph as part of the 'matrix concentration (Tropp's matrix Chernoff via Lieb concavity)' bracket, but its actual title is 'The endpoint multilinear Kakeya theorem via the Borsuk-Ulam theorem' — a proof of multilinear Kakeya, not a matrix-concentration result. Fixed: - §2 chain: moved \cite{carbery-valdimarsson} out of the matrix-concentration bracket and into the 'multilinear Kakeya endpoint' bracket alongside \cite{guth-endpoint}, which is where it actually belongs. (Carbery-Valdimarsson gives an alternate Borsuk-Ulam proof of the same endpoint theorem.) Matrix-concentration bracket now correctly cites only \cite{tropp-matrix-chernoff}. - §9.1 Related work 'Kakeya problem and harmonic analysis' paragraph: moved \cite{carbery-valdimarsson} from the Brascamp-Lieb bracket to an inline parenthetical next to \cite{guth-endpoint} — 'Guth's multilinear Kakeya endpoint (with the Borsuk-Ulam-based proof of [17])'. FEEDBACK 4 — D4 main-results downstream quality evidence Reviewer flag: the consolidated-verdict '9/12 Δppl wins' row in §5.2 looks strong at a glance; the accompanying prose acknowledges the three losses are 'inside the bf16 floor at n=4', but readers who only scan the table see '9/12 wins, 3 baseline wins' and miss the caveat. Publication-grade standards require n ≥ 32. Fixed: - §5.2 consolidated-verdict table: the 'Δppl ratio (< 1.0)' row now shows '9/12 wins | (3 sub-floor) | 0' instead of '9/12 wins | 0 | 3 baseline wins'. The sub-floor ties are visually grouped with the ties column, not the baseline-wins column. - Added a table-footnote with asterisk marker directly beneath the table: 'At n=4 passages the FlashAttention bf16 reproducibility floor is ~1% |Δppl| (§7); the three baseline wins rows on |Δppl| are all sub-floor near-lossless ties ... Deployment-realistic n=32 |Δppl| numbers with 95% CI are in §6'. Reader cannot miss the caveat. - §5.2 closing paragraph: rewrote to say 'Publication-grade |Δppl| tightening requires n ≥ 32 (§7 caveat 1); the E8-vs-D4 comparison in §6 uses n=32 with Student-t 95% CI to eliminate this confound'. - Abstract paragraph 3: expanded the 9/12 win statement to 'On |Δppl| at n=4 passages the D4 variant wins 9/12 pairs; the three losses are all < 1% absolute on both sides, inside the FlashAttention bf16 reproducibility floor at this sample size (§7), and the deployment-operating-point win at qrange=10 is 4/4 at 1.8-5.3x improvement'. The qualifier propagates to the abstract. - Conclusion paragraph 2: same qualifier propagated. BUILD latexmk -pdf clean rebuild: 15 pages (unchanged from PR #42 trim), 455 KB (+3 KB due to new table footnote + expanded conclusion + Fact 2.2 explanation paragraph), zero undefined references, zero LaTeX errors. The \newtheorem{fact} declaration shares the theorem counter with proposition / theorem / lemma / remark so Fact 2.2 / Proposition 2.1 / Proposition 2.2 numbering is internally consistent.
