 """Verify boilerplate copyright headers in source files.
 
-Policy:
-  - Files that already contain a copyright year are accepted.
-  - Files without a year must match the year-less boilerplate template.
+Two checks are applied:
+
+  1. All files: the header must match the boilerplate template once any
+     copyright year is normalized out, so a year-bearing header and a
+     year-less header both validate against the single year-less template.
+  2. New files (added relative to the base branch): the header must
+     additionally be year-less; a hardcoded copyright year is rejected.
+
+New-file detection compares against the base branch (--base-ref, default
+$TARGET_BRANCH or master), resolved as origin/<ref> then <ref>. If the base
+cannot be resolved, or files cannot be listed, the run fails rather than
+passing vacuously.
