New validation logic (the Tl, Zq, gQ, tK, and vt/hQ helpers) detects malformed or unloadable hook entries. It specifically flags cases where a PreToolUse or PermissionRequest hook entry cannot be loaded, warning that this may mean the permission guard it sits beside won't be applied until the entry is fixed or removed.
Stricter hook-config validation for PreToolUse/PermissionRequest guard entries
Malformed permission-hook entries are now flagged with a warning that the neighbouring permission guard may not apply.
