 ## [Unreleased]
 
+### Added
+- **CJK–MyST spacing rule for zh-cn**: New language-config rule instructs Claude to insert a space between Chinese characters and inline MyST directives (`{doc}`, `{ref}`, etc.) or Markdown links, preventing rendering failures (e.g. `请参阅 {doc}` not `请参阅{doc}`)
+- **MyST target-label blank-line cleanup**: `reconstructFromComponents` now strips blank lines between MyST target labels (`(label)=`) and headings in post-processing, so targets always attach to their heading correctly
+- **1 test** for target-label blank-line removal (934 → 935 total)
+
 ## [0.12.3] - 2026-03-24
 
 ### Fixed
