-# Preserve git worktree context - prevent HEAD corruption in worktrees

+# GIT WORKTREE CONTEXT HANDLING
+# =============================================================================

+# corruption. However, we must also CLEAR these variables when NOT in a worktree
+# to prevent cross-worktree contamination (files leaking between worktrees).
+#
+# The bug: If GIT_DIR/GIT_WORK_TREE are set from a previous worktree session
+# and this hook runs in the main repo (where .git is a directory, not a file),
+# git commands will target the wrong repository, causing files to appear as
+# untracked in the wrong location.
+#
+# Fix: Explicitly unset these variables when NOT in a worktree context.
