Figure, table and section ledger

Editorial contribution type: Datasets, benchmarks & measurement resources (primary) · Learning & optimization algorithms.

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.

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. Two infrastructure gaps and benchmark construction

    Explains why both executable evaluation and an interactive training environment are needed.

  2. Benchmarking and agent training

    Separates zero-shot diagnosis from SFT, offline/online RL and scaling experiments.

  3. Generalization, failures and documentation

    Adds external suites, negative reward shaping, licensing and complete prompt templates.

Problem, claim and contribution

The introduction distinguishes domain knowledge from executable biomedical coding, making the infrastructure contribution more concrete than a generic medical-agent claim.

Section 1, p. 2 · Main paper

Argument and section order

Construction, environment, evaluation and training occupy separate sections, so readers can identify which artifact each experiment validates.

Sections 3–5 · Main paper

Figures, captions and visual explanation

Figure 2 uses color-coded data, agent, interface and sandbox regions, with a lower interaction strip translating the architecture into an episode.

Figure 2, p. 5 · Main paper

Tables, comparisons and evidence

Table 4 groups post-training variants under fixed backbones; external Table 5 and the unsuccessful repetition-penalty ablation prevent in-distribution improvement from standing alone.

Tables 4–5 and 13, pp. 8–9 and 32 · Main paper

Appendix and reproducibility

Per-source transformations, split rules, access licenses, task prompts and the human evaluation are documented individually instead of hidden behind one aggregate dataset count.

Appendices A.3, C, F.8 and G · Main paper

Clarity and writing conventions

Claims such as privacy-preserving or containerization guaranteeing compliance need narrower language: environment isolation, data permissions and external debugging-service routing are different controls.

What to reuse—and what not to infer

Transferable lesson: For an environment paper, align each claimed capability with its own evidence: execution validity, training utility, generalization, cost and failure analysis.

Boundary: The prompts expose test-label directory placeholders, requiring an explicit leakage/access audit before reuse. Tables 3 and 4 report different averages for identical 7B backbone cells, and Table 8 turn counts exceed the stated 15-turn cap. Medical-looking case code is not independently validated clinical guidance.

Apply this lesson using the argument and evidence worksheet.
