+        non-source Polylang language of `source_id`, links them all into
+        one Polylang group via a single pll_save_post_translations() call,
+        and enqueues each translation. Same shape as clicking "Translate
+        All" in the wp-admin Languages meta-box but scriptable.
+
+        Use cases:
+          - Re-fan-out translations on an admin-authored CPT (the publish
+            hook only fires for public-referral posts, so admin-created
+            posts need this explicit invocation).
+          - Recover from a publish-flow hook that didn't fire or whose
+            Polylang group got disconnected mid-flight.
+
+        Raises ValueError if source_id is not a positive integer — the
+        backend's absint() sanitization would otherwise silently coerce
+        a negative ID into a different positive ID and enqueue
+        translations for the wrong source post.
