Fast Main-Text Chinese Review & Bidirectional PDF Sync (`informs-zh-review`)

Enable rapid human reading of INFORMS manuscripts in Chinese PDF form—stripping out heavy Online Appendix proofs—and cleanly synchronize PDF highlights, strikeouts, sticky notes, and handwritten ink markups back into both the English and Chinese LaTeX sources under strict Git version control.

1. Mandatory Git Versioning Discipline

Core manuscript sources (*.tex, *.bib, and zh_review/main_zh.tex) MUST be tracked in Git before and after every operation.

Pre-Flight Check: Run git status in the project directory.
- If not yet a Git repository: run git init, ensure .gitignore excludes LaTeX build artifacts and zh_review/annot_snapshots/, and create an initial baseline commit (chore: baseline manuscript before zh-review).
- If uncommitted edits exist before applying PDF annotations: commit a clean checkpoint (checkpoint: before applying <pdf_name> annotations) so every change remains strictly reversible.
Post-Sync Commit: After compiling and verifying both updated sources, commit both English and Chinese .tex files atomically: git add <en_tex_files> zh_review/main_zh.tex && git commit -m "sync(zh-review): apply annotations from <pdf_name>"

2. Workflow A: Fast Main-Text EN -> ZH PDF Generation

Use when the user asks to translate an English .tex manuscript (or selected sections) into a Chinese PDF for quick review.

Step 1: Scope Filter (Main Text Only, Skip Online Appendix)

Translate ONLY the main manuscript:
- Title, Abstract, Keywords
- Main body sections (Introduction through Conclusion)
- Formal Theorem, Proposition, Lemma, Corollary, Assumption, and Definition statements
- Main-text Figures (referencing ../figures/...), booktabs Tables, and numbered Algorithms
Strictly STOP at \ECSwitch / \appendix / Online Appendix: Do NOT translate Online Appendix proofs, helper lemmas, or supplementary tables. Append one closing italicized note at the end of zh_review/main_zh.tex: \textit{Note omitted Online Appendix notice in Chinese} -> \textit{注：Online Appendix（详细证明、辅助引理及补充数值实验）已按快速审阅模式略去。}
Skip translating the bibliography entries. Render in-text citations cleanly as Author (Year) or (Author Year) so compilation never stalls on BibTeX lookups.

Step 2: 1-to-1 Structural Mirror & Sync Anchors

Write the translated file to zh_review/main_zh.tex based on ctex-review-template.tex.
Preserve identical section numbering, equation numbering, theorem/proposition/lemma counters, figure/table numbers, and paragraph breaks as the English source.
Place a lightweight anchor comment immediately above every paragraph, theorem block, table, and displayed equation:
```
% [EN-SYNC: main.tex:sec2:p3]
```
Record the source English Git commit hash in the file header (% Synced from ../main.tex @ <short_hash>).

Step 3: Translation Craft for OR/MS Scholars

Preserve 100% of Mathematical Content: Keep all inline $...$ , displayed equations, variables, and theorem conditions identical to the English manuscript.
Natural Chinese Academic Prose: Write fluent, concise Chinese OR/MS prose—avoid stiff word-by-word translationese.
Terminology Lock: Maintain a strict 1-to-1 Chinese-to-English term mapping matching the English manuscript's canonical terms. On first occurrence of key technical constructs, attach the canonical English term in parentheses (e.g., base-stock policy, submodularity, cross-moment regularity).

Step 4: Compile, Visually Inspect & Commit

Compile inside zh_review/ using xelatex:

xelatex -interaction=nonstopmode -halt-on-error main_zh.tex
xelatex -interaction=nonstopmode -halt-on-error main_zh.tex

(On Windows, if xelatex is not on PATH, check C:\texlive\2021\bin\win32\xelatex.exe.)

Run informs-writing's check_pdf_layout.py on zh_review/main_zh.pdf (--render-flagged zh_review/annot_snapshots) and inspect flagged or table/figure pages via read_file to catch missing CJK/math glyphs, overlapping text, blank pages, or oversized whitespace voids; remove temporary PNGs afterward.
Verify zh_review/main_zh.pdf exists with non-zero size and zero blocking visual/glyph defects, commit zh_review/main_zh.tex to Git (feat(zh-review): generate main-text Chinese review PDF), and present a clickable file:/// link to zh_review/main_zh.pdf.

3. Workflow B: Annotated Chinese PDF -> Bidirectional EN + ZH Sync

Use when the user returns an annotated Chinese PDF (highlights, strikeouts, sticky notes, free-text comments, or iPad handwritten ink) and asks to update both versions.

Step 1: Dual-Channel Annotation Extraction

Run extract_pdf_annotations.py to capture both embedded PDF annotations and visual page snapshots:

python "<skill_dir>/scripts/extract_pdf_annotations.py" "<annotated.pdf>" --render-dir "<project>/zh_review/annot_snapshots"

Channel 1 (Structured /Annot Report): Read the script output listing every page number, annotation type (Highlight, StrikeOut, Underline, Text, FreeText, Caret, Ink), exact underlying Chinese text, surrounding context, and user comment.
Channel 2 (Visual Inspection for Handwritten / Flattened Markups):
- Open every rendered PNG in <project>/zh_review/annot_snapshots/ with read_file to inspect handwritten margin notes, circled equations, arrows, or crossed-out phrases.
- If the script reports 0 embedded /Annot objects (common when tablet apps export flattened PDFs), inspect pages directly via read_file on the PDF or render pages with --render-all-if-flat so no handwritten markup is missed.

Step 2: Map to `% [EN-SYNC: ...]` Anchors & Triage

Match each PDF annotation to its exact % [EN-SYNC: ...] block in zh_review/main_zh.tex and the corresponding lines in the English .tex source.
If a margin note is unambiguous (e.g., tighten intuition, fix a term, drop a symbol, rewrite an awkward claim, adjust scope), apply it directly. Only ask the user if an annotation poses an open modeling choice that alters theorem assumptions or mathematical truth.

Step 3: Dual-Standard Bidirectional Editing

Update the English .tex First (Enforcing informs-writing Standards):
- Apply all 7 Iron Rules from informs-writing: zero orphan notation, intuition-first concept onboarding, concrete SVO prose, positive upfront conditions (no defensive disclaimers), patterns/rounded magnitudes in prose, strict definition & terminology lock, and zero chat-context or revision-history leakage.
- Critical Timeless-Prose Check: Translate the scholarly intent of the user's Chinese annotation into native INFORMS English. NEVER write meta-text such as "Unlike the previous version...", "Following the correction...", or "We updated...". The edited passage must read as if written cleanly from day one.
Update zh_review/main_zh.tex in Lockstep:
- Mirror the updated English logic, wording, and notation identically in zh_review/main_zh.tex so both files stay 1-to-1 synchronized.

Step 4: Audit, Recompile, Visually Inspect, Clean & Commit

Run informs-writing's audit_informs_draft.py (and check_prose_craft.py on revised paragraphs) against the updated English .tex and resolve any flagged issues.
Recompile zh_review/main_zh.pdf with xelatex (and recompile the English PDF if informs4.cls is present).
Run informs-writing's check_pdf_layout.py on the compiled PDF(s) (--render-flagged zh_review/annot_snapshots), inspect any flagged pages or revised tables/figures via read_file, and fix any glyph garbling, giant whitespace gaps, overlaps, or margin overflows before finishing.
Remove temporary zh_review/annot_snapshots/ PNGs so binary snapshots do not clutter Git.
Commit both updated .tex files to Git (sync(zh-review): apply PDF annotations from <pdf_name>).
Present a concise Revision Log Table (PDF Page | Annotation Summary | English Edit Location & Change | Chinese Sync Edit | Git Commit) with clickable file:/// links to the updated PDFs and .tex files.
