CLASSIFICATION

Hunk 1 — line 297 (4.1.1 → 4.2 boundary)

• Original: 2 blank lines between **Viện dẫn:** ... and ### 4.2 dot_domains.
• Reconstructed: 1 blank line.
• Type: structural-only — whitespace normalization.
• Impact: none. Markdown collapses identically.

Hunk 2 — line 418-422 (6.1 Trạng thái)

• Original: heading + 1 blank + code fence.
• Reconstructed: heading + 2 blank + code fence.
• Type: structural-only — whitespace.
• Cause: Renderer always emits \n\n between heading and body; the original had this single section atypically tight.
• Impact: none.

CONTENT-AFFECTING DIFFERENCES

NONE. Every byte of substantive content (text, code blocks, tables, headings, callouts) is preserved.

RENDERING RULES APPLIED

1. ✅ Skipped synthetic root D38-DIEU35-ROOT
2. ✅ Preamble D38-DIEU35-S0 rendered as-is (its body already begins with # H1)
3. ✅ Parent placeholder bodies ((parent — see children ...)) suppressed for D38-DIEU35-S4 and D38-DIEU35-S6
4. ✅ Body text preserved verbatim, preorder DFS by materialized path
5. ✅ depth=2 → ##, depth=3 → ###
6. ✅ §8.2 (D38-DIEU35-S8-P3, body length 1) — heading-only
