+# Issue: #1430 — memory_mine.py ran during git commit due to backtick substitution
+#
+# Problem: git commit -m "message with `code`" triggers shell evaluation
+# of backtick-wrapped content during hook processing.
+#
+# Fix: Strip or escape backticks from commit messages before they reach hooks.
+# Safe pattern: use git commit -F <file> instead of -m for code-containing messages.
