 - **`stamp_placeholders` policy key** (default `[]`, so nothing changes for a repo that does not set it): literal placeholders such as `["TBD"]`, at most 16, one line and 32 characters each, never `{version}` and never a version. It needs `min_gstack_version` at the release that introduced it.
 
 ### Fixed
-- **`lib/stamp-only.ts`:** `stampOnlyLine` takes the policy's placeholders. On a line the branch added itself (named by its position), a placeholder inside a `stamp_patterns` template may become that template at the new version. The built-in forms, base lines (including one whose text duplicates a branch line) and undeclared placeholders are still refused. Finish's `stampedFiles`, the receipt carry and the tree receipt share it.
-- **`bin/gstack-ship-receipt` carry:** the carried receipt's `version` is HEAD's, read the way `write` reads it, instead of the version copied from the old receipt.
+- **`lib/stamp-only.ts`:** `stampOnlyLine` takes the policy's placeholders. On a line the branch added itself (named by its position), a placeholder inside a `stamp_patterns` template may become that template at the new version, alongside any stamp-form version move on the same line. The built-in forms, a bare `{version}` template, base lines (including one whose text duplicates a branch line) and undeclared placeholders are still refused. Finish's `stampedFiles`, the receipt carry and the tree receipt share it.
+- **`bin/gstack-ship-receipt` carry:** the carried receipt's `version` is HEAD's, read the way `write` reads it, instead of the version copied from the old receipt. A head with no version source keeps the version `write --version` recorded.
 
 ### Tests
 - `test/tree-receipt-stamp-sensitive.test.ts`, `test/gstack-ship-receipt-docs.test.ts`: the shared predicate and the carry classifier accept gbrain's `since: 'TBD'` → `since: '0.60.553.0'` row and refuse an undeclared placeholder, a base row, a duplicated base copy, a built-in form and a line no template matches.
