 ## Regression Fixes
 
-**What qualifies:** Bugs introduced in recent versions (same major.minor)
+**What qualifies:** Bugs introduced in a previous major.minor version (e.g., a 1.8 feature that broke in 1.9)
+
+**Skip changelog entirely** when the regression was introduced by another change in the same version cycle. For example, if a 1.9 bug fix introduced a new bug also fixed in 1.9, the fix does not need a changelog entry — the original entry covers the feature area.

+### Regex Match Array Format
+
+`ensureFileRegexMatches` (and variants like `ensureTypstFileRegexMatches`, `ensureLatexFileRegexMatches`) takes two arrays:
+
+```yaml
+ensureFileRegexMatches:
+  -                                   # First array: patterns that MUST match
+    - "pattern1"
+    - "pattern2"
+  -                                   # Second array (optional): patterns that must NOT match
+    - "forbidden-pattern"
+```
+
+Both patterns in the first array must be found. Any pattern in the second array causes failure if found.
