Figure, table and section ledger

Editorial contribution type: Learning & optimization algorithms (primary) · Inference, algorithms & systems efficiency.

Layout extraction, not a required paper template. Counts are distinct caption labels; a multi-panel figure counts once. Section spans are estimated from heading positions, including floats and whitespace. Method and limitations.

Argument and organization

1. Bottlenecks and dual consistency

   Pairformer recycling and diffusion sampling motivate two separately trained consistency modules.

2. Temporal geometry and applications

   A variable-length schedule precedes structure prediction, binder-design and training-dynamics evidence.

Problem, claim and contribution

The opening decomposes runtime before proposing acceleration, making the two consistency targets traceable to measured bottlenecks rather than a generic compression claim.

Section 1, Figure 1; Section 3.2 · Main paper

Argument and section order

A compact stage-by-module loss table makes the sequential training schedule legible before the equations, distinguishing diffusion training from later Pairformer refinement.

Table 1 and Section 3.2, pages 3–4 · Main paper

Figures, captions and visual explanation

Figure 2 aligns original and compressed pipelines horizontally, reuses module colors and separates Pairformer/diffusion regions; dashed training connections contrast with solid inference flow.

Figure 2, page 3 · Main paper

Tables, comparisons and evidence

Best- and worst-sample RMSD columns reveal a tradeoff hidden by an overall success claim: DCFold improves worst-sample <2 Å success to 71.43% but trails AlphaFold3 on best-sample success, 78.57% versus 82.86%.

Table 2, page 6 · Main paper

Appendix and reproducibility

Compute, binder filtering, length-binned runtimes and generated-sample counts are usefully separated; downstream timings include additional ProteinMPNN/re-prediction work rather than equating folding speed with complete design speed.

Appendices B–C, pages 16–18, Tables 7–8 · Main paper

Clarity and writing conventions

The derivation needs correction or clarification: squared derivative ratios in Equation 20 disappear in Equation 21, while Table 3 calls differently scaled TM-score changes absolute improvements. These should not be copied uncritically.

Appendix A.2, Equations 20–22, page 16; Table 3, page 6 · Main paper

What to reuse—and what not to infer

Transferable lesson: Connect each compressed component to a measured bottleneck, show stage-specific losses beside the architecture, and retain best/worst-case evidence instead of one headline score.

Boundary: Experiments use a Protenix-based AlphaFold3 reproduction and computational binder filters, not wet-lab binding validation. The temporal-Fisher derivation and appendix target-family labels require expert checking; no independent reproduction was performed.

Apply this lesson using the argument and evidence worksheet.
