Editorial contribution type: Domain-grounded methods & physical systems (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.

Extraction notes: No attached appendix boundary detected. Zero means no recognized caption, not independently verified absence.
Source-bound correction: Checked 2026-10-25 against the manuscript-wide writing read, physical-page bounding boxes and full-page rasters 3, 4, 7. Unnumbered main headings have 10.7475-height glyphs, not the smaller Pipeline Overview, Foresight Augmentation or Robustness Analysis subsections. Figures 1–4 and tables 1–3 match extracted caption candidates, with no restoration needed. Algorithms 1–2 on p.4 are not figure/table counts. No attached appendix; linked project/arXiv materials are excluded from measurements.
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
- Introduction; Related Work
Uses reliability, instruction ambiguity and unseen-task examples to motivate multimodal goals and training-time foresight alongside imitation learning.
- Method
Introduces the policy pipeline, goal-image generation and foresight loss before giving implementation detail and separate training/inference algorithms.
- Experiments
Starts with five explicit questions, then separates data collection, simulation, physical-robot tests, generated-goal inference and qualitative robustness observations.
- Conclusion and Future Work; References
Restates the policy contribution while identifying high-precision scene failures and intermediate-goal refinement as future work; no attached appendix follows.
Problem, claim and contribution
Contrasts language-only and image-only goals using concrete manipulation ambiguities rather than generic multimodal claims. The motivation separates reliable action generation, distinguishing similar tasks and unseen-task behavior. Human foresight is an analogy for a training signal, not evidence that the policy reasons like a person.

Argument and section order
The architecture overview precedes the goal-imagination and foresight modules. Side-by-side training and inference pseudocode makes the removed foresight branch, fixed inference latent and temporal action aggregation inspectable. Five experiment questions provide a useful organizing contract for the later modality, foresight, generalization, generated-goal and disturbance sections.

Figures, captions and visual explanation
Figure 1 distinguishes training outputs/losses from the deployed action path and identifies the goal-image module separately from the policy. Figure 2 aligns a common starting scene with instruction-conditioned goal images. Scene inventories in Figures 3–4 communicate what the simulation and robot tasks physically contain; they are task-context visuals, not standalone success-rate evidence.

Tables, comparisons and evidence
Table 1 reports task counts and simulation success by category; Table 2 retains raw real-robot successes/trials and a missing entry. The full model loses to its no-foresight ablation in Scenario II (11/40 versus 13/40). Generated-goal Table 3 concerns separately trained Scenario III policies, not every robot result. The headline 41% improvement corresponds to a 41-percentage-point simulation gap (86% versus 45%), and should not be rewritten as a relative gain or universal deployment result.

Appendix and reproducibility
Training/inference pseudocode, camera and demonstration settings, baseline protocol and trial counts remain in the proceedings body. Custom-environment tutorials, videos and further demonstrations are routed to the project homepage instead of an attached appendix. Directory inspection does not validate those assets; robustness-video claims remain qualitative statements in the read source.

Clarity and writing conventions
The conclusion names high-precision scene limitations rather than hiding them behind the simulation result. The generated-goal discussion supplies a concrete error: confusing the requested test-tube hole with a neighboring hole. An adaptation should preserve this specificity, distinguish observed outcomes from the proposed semantic explanation, and report the approximately four-second goal-image generation cost separately from policy control latency.

What to reuse—and what not to infer
Transferable lesson: For a robotics application, show training versus deployment explicitly, formulate experiment questions before results, and keep simulation percentages, physical trial counts and qualitative disturbance demonstrations as separate evidence types. Retain failed cases and missing comparisons.
Boundary: Small real-robot denominators and narrow unseen-object/color protocols do not establish unrestricted generalization. The generated-goal comparison is restricted to Scenario III and uses a separate training setup. The full model is not best in every real scenario; missing table entries are not zeros. No video, code, attached appendix or independent robot evaluation was inspected.
