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. Complete numbered-caption inventory cross-checked against source text; restored real punctuation-free captions and excluded inline references. Selected pages visually inspected, not every image/table.
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.

Main text
Argument and organization
- Problem and contribution
Names the pixel-decoding bridge between understanding and generation as the bottleneck, then proposes reasoning within a shared semantic latent space.
- Argument sequence
Moves from tokenizer and modality experts to training, base tasks, self-reflection, spatial planning and world modeling.
- Evidence and verification
Generation tables separate specialized and unified systems and distinguish base, self-reward and external pixel-reward variants.
Problem, claim and contribution
Names the pixel-decoding bridge between understanding and generation as the bottleneck, then proposes reasoning within a shared semantic latent space.
Introduction · Main paper
Argument and section order
Moves from tokenizer and modality experts to training, base tasks, self-reflection, spatial planning and world modeling.
Sections 3–4 · Main paper
Figures, captions and visual explanation
The three-panel architecture separates behavior-aligned tokenization, the cross-modal transformer and an optional pixel decoder; the legend distinguishes continuous and quantized features.
Figure 2, p. 4 · Main paper
Tables, comparisons and evidence
Generation tables separate specialized and unified systems and distinguish base, self-reward and external pixel-reward variants.
Tables 2–3, p. 10 · Main paper
Appendix and reproducibility
Additional training specifications and before/after GRPO examples expose details behind the concise main-stage description.
Appendices A–B; pp. 20–26 · Main paper
Clarity and writing conventions
Component names recur in architecture labels and subsection titles; captions describe what the branches do rather than merely listing modules.

What to reuse—and what not to infer
Transferable lesson: Show which representation crosses each interface, and keep optional visualization decoding distinct from reasoning computation.
Boundary: The public manuscript is longer than a NeurIPS initial submission. Avoid converting 'without pixel mediation' into a claim that no pixel decoder is ever used.
Apply this lesson using the argument and evidence worksheet.
