Figure, table and section ledger

Editorial contribution type: Training, objectives & optimization (primary).

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.

Section-by-section lengths and source pages

The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

Argument and organization

1. 1 Introduction; 2 Methodology

   Defines an unconditional pose prior, task-specific inverse problems and a simple denoising regularizer before whole-body extension.

2. 2.4–2.5 Scheduling and whole-body prior

   Motivates truncated noise schedules and separates part-specific, fused and mixed-data models.

3. 3 Experiments; 4 Conclusion

   Organizes body, hand/face and whole-body tasks separately, then ablates scheduling and mixed training.

Problem, claim and contribution

The prior is reusable across tasks through test-time optimization, with a different measurement loss for each inverse problem rather than one universal predictor.

Sections 1–2.3, physical pp.1–3 · Main paper

Argument and section order

A worked regularization derivation and optimization algorithm precede the whole-body model, separating inference procedure from mixed-data training.

Section 2.3 and Algorithm 1, pp.3–4 · Main paper

Figures, captions and visual explanation

The mixed-training diagram distinguishes unavailable parts, which receive no loss, from deliberately masked whole-body parts, which remain supervised.

Figure 4, p.5 · Main paper

Tables, comparisons and evidence

Pose-generation results explicitly show that high pairwise diversity can accompany implausible samples; completion reports min/mean/std over ten hypotheses rather than only best-case error.

Table 1 and Figure 5, p.5; Table 7 and Section 3.4, p.7 · Main paper

Appendix and reproducibility

Metrics, runtime, baseline implementations, extra tasks, rotation representation and alternate inverse solvers are delegated to supplementary material; only main pointers were inspected.

Sections 3.1 and 3.5, pp.5,8 · Main paper

Clarity and writing conventions

The text notes that the best timestep range depends on task noise, qualifying the appeal of one fixed scheduling recipe.

Sections 2.4 and 3.5, pp.4,8 · Main paper

What to reuse—and what not to infer

Transferable lesson: Show a counterexample to an attractive metric and report both average and best-of-many performance for ambiguous reconstruction.

Boundary: Prior plausibility and aligned pose errors do not prove biomechanical or clinical validity. Preserve slash-separated statistic order: Table 5 labels median/mean/std, whereas the prose calls the leading 8.76 value a mean. Mathematical equivalence was scanned, not exhaustively verified.

Apply this lesson using the argument and evidence worksheet.

Writing-focused manuscript scan + selected visuals inspected

Main text

Writing-oriented scan across the main manuscript, physical PDF pp.1–8, covering framing, section progression, method explanations, captions, comparison protocols and concluding scope; reference boundary checked. Selected full-page rasters were inspected. Not exhaustive line-by-line reading, proof verification or experimental reproduction.

Appendix / supplement

Main-paper appendix/supplement references were checked. A separate supplementary source is linked in the inventory but was not retrieved or inspected; its contents are not included in the reading or visual-page counts.

This is a writing-focused scan of the manuscript and the stated supplementary scope: framing, organization, visual explanation, evidence presentation and wording. It is not a line-by-line proof audit, reproduction of results or exhaustive scientific review.
