Figure, table and section ledger

Editorial contribution type: Architecture & representation (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.

Source-bound correction: Top-level heading and reference/appendix boundaries checked against source PDF text. Bibliography titles/author initials, numbered contribution/property bullets, diagram steps, equations and TOC entries are not substantive headings. Section spans are page-coordinate estimates, not ink area or prose-only length. This is an author manuscript mirror, not a verified accepted-version template. Source layout uses physical single-column y/page-height, including equation-heavy pages.

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. Action-to-visual ambiguity

   Defines setup-dependent action interpretation as the generalization obstacle.

2. Calibration-conditioned model and ranking

   Separates world-model training from its use as a policy-evaluation simulator.

3. Quality, consistency and decision making

   Tests visual prediction, cross-view geometry and selected policy-improvement tasks independently.

Problem, claim and contribution

The same numerical robot action can look different under a new camera or embodiment. Stating that ambiguity first makes the calibration episode an answer to a concrete missing variable.

Introduction; Section 3.1 · Main paper

Argument and section order

The paper separates calibration-based modeling, learning and policy ranking, then evaluates video quality, spatial consistency and policy improvement. This prevents a visually plausible rollout from being treated as sufficient decision-making evidence.

Sections 3.1–3.4 and 4.2–4.5 · Main paper

Figures, captions and visual explanation

Distinct colored input groups identify calibration, interaction history and future actions. Pose embeddings and video latents are drawn separately before entering the DiT, making the conditioning interface explicit.

Figure 2, PDF p. 4 · Main paper

Tables, comparisons and evidence

The policy table states that it is a diagnostic subset with oracle headroom. It distinguishes direct policy, simulated ranking and oracle ranking; this qualification is critical because it is not an all-task success-rate claim.

Tables 2–3, PDF p. 8 · Main paper

Appendix and reproducibility

Additional tasks without consistent oracle headroom and categorized failures are retained, alongside inference configuration and efficiency. The appendix therefore tests limits of the claimed use case rather than serving only as a gallery of successes.

Appendices C.4.3–F · Main paper

Clarity and writing conventions

The wording distinguishes zero additional training from zero additional information: calibration is still an input. Explicitly define the meaning of zero-shot when a model receives setup-specific context.

Section 4.4 and Table 3 caption · Main paper

What to reuse—and what not to infer

Transferable lesson: Separate model fidelity from downstream usefulness, and disclose diagnostic task selection beside the corresponding results.

Boundary: The public arXiv revision is not verified identical to the accepted version. The displayed oracle-headroom subset cannot establish an average benefit across all manipulation tasks.
