Current source `v3.10.0-rc2` acted as a negative control and blocked the same payloads.\n- **Patched versions:** Patched in version 3.10.0, which includes the path-safety rejections seen in the release candidate.\n- **Root cause:** Stable reader paths still construct raw XML filenames from unsafe selectors, poisoned index state, or unsafe file identifiers.\n\nI confirmed four public stable entrypoints return parsed outside-root content: a parent-segment traversal frame name, a poisoned fulltext index filename, a poisoned LU id, and an unsafe NKJP header file identifier.
