# Reading check results

> The ten quality checks of each version, what each status means, how to open the evidence, rerun, and the References, Compare and Similarity panels.

Each version has a quality report made of **10 checks**. Results are in the **Vấn đề** (Issues) panel of the Documents tab; a check that has not run is still listed with the status "Chưa chạy" (Not run) instead of being hidden.

## Statuses

| Status | Meaning |
| --- | --- |
| Đạt (`pass`) | Meets the requirement |
| Cần xem lại (`warn`) | Something worth a look, not blocking |
| Không đạt (`fail`) | Does not meet the requirement |
| Lỗi (`error`) | Could not run (TeX error, PDF without a text layer, network error…). This is **not** a pass |
| Chưa cấu hình (`not_configured`) | Not enough to run the check (venue is not double-blind, Turnitin not configured…) |
| Chưa chạy (Not run) | This check has not run on the version |

## The ten checks

| Check | What it does |
| --- | --- |
| Toàn vẹn gói source (Source package integrity) | The zip is readable, has no path escaping the folder (zip-slip) or symlinks, and is within size limits; no zip is an error |
| Biên dịch LaTeX (LaTeX compile) | Runs `latexmk` in a separate TeX service; a TeX error is **Lỗi** with the `! …` block; warnings such as Overfull boxes are **Cần xem lại** |
| Khớp source ↔ PDF nộp (Source ↔ submitted PDF match) | Whether the PDF you submitted really is the one compiled from the source: Dice coefficient ≥ 0.98 and coverage ≥ 0.99 pass; 0.95–0.98 needs a look; a scanned PDF or one without extractable text is an error |
| So sánh với bản trước (Compare with previous) | latexdiff PDF against the previous version (lines added/removed); no previous version means not configured |
| Dọn source (Source cleanup) | Files in the zip that no compile read, comments, `TODO`, `chktex` warnings: evidence for cleanup, not a verdict |
| Ẩn danh (Anonymity) | Only runs when the venue edition is double-blind: names, emails, affiliations in the source; author metadata and arXiv stamps in the PDF |
| Template và số trang (Template and page count) | `\documentclass` against the venue's template; page count against the page limit; a mismatch needs a look |
| Kiểm tài liệu tham khảo (Reference check) | Checks each entry against DOI, Crossref, DataCite, OpenAlex, arXiv (and Semantic Scholar if a key is set) |
| Tương đồng (Similarity) | Turnitin; when not configured it makes no network call and shows no fake percentage |
| Đối chiếu reviewer (Reviewer cross-check) | Matches reviewer comments against the diff; needs a previous version and imported reviews (see [Reviews and reviewer cross-check](/en/huong-dan/doi-chieu-reviewer/)) |

## See the evidence and rerun

Click a row to open its findings. The example below is the LaTeX compile check reporting **Cần xem lại** because of "39 hộp Overfull trong bản compile" (39 Overfull boxes in the compile).

![Opening a check to see its findings](../../../../assets/shots/van-de-chi-tiet.webp)

- **Bằng chứng** (Evidence): opens the check run's artifact in the work window (compile log, PDF diff, flattened TeX).
- **Chạy lại** (Rerun) on each row, or **Chạy lại tất cả** (Rerun all); **Tải lại** (Reload) refreshes the table when the worker has just finished.
- When a finding points to a source line, click it to jump to [Source](/en/huong-dan/trang-cong-trinh/#source) mode.

## References

The **Tham chiếu** (References) panel has a table of every bibliography entry, its verdict and a source link or suggested DOI. Click **Chạy lại kiểm ref** (Rerun reference check) to run it; the table updates when the worker finishes.

## latexdiff comparison

The **So sánh** (Compare) mode of the Documents tab shows the latexdiff PDF or a TeX text diff. It needs the artifact of a check run that had a previous version; if there is none, the page says so. See [Work page](/en/huong-dan/trang-cong-trinh/#compare).

## Similarity

The **Tương đồng (Turnitin)** (Similarity) panel shows the overlap score Turnitin returned for exactly that version; nothing is estimated or computed locally. If Turnitin is not configured, the panel says so and links to [Settings → Similarity](/en/huong-dan/cai-dat/#similarity-turnitin). Once configured, run it and see the percentage, matching sources and a link to the PDF report (valid for 600 seconds).
