Extracting `.docx.md` to `source.dj` + `bilingual.dj`

When the input is a .docx.md file (already pandoc markdown, not plain text), the extraction differs from the standard DOCX→plain workflow. The markdown preserves formatting artifacts that need specific handling.

CN/EN boundary detection in merged lines

Pandoc markdown often merges CN and EN text on heading lines where the DOCX had multiple runs in the same paragraph:

# **三、重视文化教育，重塑人生价值** Prioritize Cultural Education; Reshape Life Values {#三、...}

The boundary regex must account for whitespace on BOTH sides of ** markers:

# WRONG: \** then \s* — fails when there's space BEFORE * (值 *Realizing)
r'[\u4e00-\u9fff](?:\*{0,2})\s*([A-Za-z])'

# WRONG: \s* then \** — fails when there's space AFTER ** (值** Prioritize)
r'[\u4e00-\u9fff]\s*\**([A-Za-z])'

# CORRECT: whitespace on both sides of optional *
r'[\u4e00-\u9fff]\s*\**\s*([A-Za-z])'

Include CJK punctuation ranges in the character class: [\u4e00-\u9fff\u3000-\u303f\uff00-\uffef]

Anchor stripping

Strip BOTH {#anchor} (pandoc heading anchors) AND [text](#link) (markdown TOC links) before further processing:

def strip_anchors(s):
    s = re.sub(r'\{#[^}]*\}', '', s)           # {#anchor}
    s = re.sub(r'\[([^\]]*)\]\([^)]*\)', r'\1', s)  # [text](#link) → text
    return s

TOC handling — two critical guards

Guard 1: Don't pair TOC CN entries with following EN lines

TOC entries often look like CN-heading-followed-by-EN (the standard pair pattern), but the following EN is actually the next TOC entry or heading:

[一、营造禅意氛围，优化工作环境\t1](#anchor)
[二、重视慈善关爱...]
...
1、Create a Chan(Zen) Atmosphere; Optimize Your Environment
2、Focus on Compassion and Care; Build Good Relationships

If the last CN TOC entry is followed by a blank line then the first EN TOC entry, the "CN → blank → EN" heading pattern will consume the first EN TOC entry. Guard against this:

def is_toc_line(line, cn_raw):
    if re.search(r'\[.*\]\(.*\)', line):  # markdown link
        return True
    if re.search(r'\t\d+', cn_raw):       # tab + page number
        return True
    return False

Skip the CN→EN and CN→blank→EN patterns when is_toc_line() returns True. These CN TOC entries should stay unpaired (en='') and get their EN from the separate EN TOC list.

Guard 2: Pair TOC EN entries forward, not backward

EN TOC entries appear as standalone non-CJK lines. They must be paired with the FIRST unpaired CN (not the last):

# CORRECT: forward iteration
for j in range(len(pairs)):
    if not pairs[j][1] and has_cjk(pairs[j][0]):
        pairs[j] = (pairs[j][0], en)
        break

# WRONG: reverse iteration (pairs last-first, shifting everything)
for j in range(len(pairs)-1, -1, -1):
    ...

Orphaned trailing `*` from italic splits

When a line has italicized EN text (*Realizing Ultimate Value*) and the split point is at the R (after the opening * is consumed by the CN cleanup), the EN text retains a trailing *: Realizing Ultimate Value*. Strip it:

def clean_en(s):
    s = re.sub(r'^\d+[、,.]\s*', '', s)
    s = re.sub(r'\*+$', '', s)                # orphaned italic close
    return s.strip()

`clean_cn` — operation order matters

Strip leading numbers BEFORE heading markers. A line like 1. # **营造禅意... starts with a digit, so ^#+\s*\** won't match until the number is gone:

def clean_cn(s):
    s = re.sub(r'^\d+\.\s*', '', s)           # leading number FIRST
    s = re.sub(r'^#+\s*\**', '', s)           # then heading markers
    s = re.sub(r'\**\s*$', '', s)             # trailing **
    s = re.sub(r'\t\d+$', '', s)              # trailing page number
    return s.strip()

Full extraction recipe

Read .docx.md text
For each line: strip anchors, detect CJK/EN
CJK lines: try split_cnen() first (merged CN+EN). If that gives EN, use it. Otherwise look ahead for EN on next line or next+blank — but SKIP if TOC-like.
EN-only lines: pair forward with first unpaired CN.
Clean: strip heading markers, leading numbers, trailing page numbers.
Write source.dj (CN only) and bilingual.dj with proper markdown structure.

bilingual.dj output format

Must follow the project convention (see reference bilingual.dj in any completed article):

# CN Title
# EN Title

---CN Subtitle
---EN Subtitle

CN Author
EN Author

- CN TOC item 1
- CN TOC item 2
...

- EN TOC item 1
- EN TOC item 2
...

CN body paragraph
EN body paragraph

CN section heading            ← plain text, no # prefix
EN section heading

...

CN sub-heading                ← plain text, e.g. "1. 创造精神财富"
EN sub-heading

Title: # prefix on both CN and EN
Subtitle: --- prefix (3 dashes, no space after)
Author: plain text, one pair
TOC: - bullet, CN block then EN block (not interleaved), blank line between blocks
Body headings: plain text, no # or ## markers. Hierarchy conveyed by numbering: 一、二、三、 for major sections, 1. 2. 3. for sub-sections
Body paragraphs: interleaved (CN line, EN line, blank)
source.dj uses # Title, ---subtitle, ## section headings — different from bilingual.dj which uses plain body headings
