What
The step that joins an array of answer strings into one comma-separated string now bails out unless the array length is a sane integer below a cap, and builds the result in a single bounded loop, so a huge or hostile array passes through untouched instead of being materialised.
Evidence
Question texts must be unique, option labels must be unique within each question
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
