 "title": "Private code assistant: one coding request with a signed receipt",
 "about": "One short coding request (a merge_intervals function with a docstring and three doctests) sent to the OpenAI-compatible chat route. The answer must hold the function and its doctests, and the call must carry a receipt that is public at /receipts/{id} and whose checks all pass. There is no verify route for a single completion, so there is no tamper step; the receipt's own checks are the proof.",
