## Release Note

RELEASE NOTE:

Start by reproducing the page-load failure and inspecting the browser console stack trace at js@3:8 and （索引）:815; the issue provides no source file or reproduction steps. Done means identifying the affected page and cause of the null __k access, then confirming the page loads without the TypeError.
