Help me reduce a large failing case to the smallest example. Ask me these questions one at a time and wait: (1) what is the exact error or wrong behavior, (2) what did I expect, (3) language, framework, and versions, (4) how to trigger it step by step, (5) whether it happens every time, (6) what I changed just before it started, (7) which files or inputs seem involved, and (8) what I have already ruled out. What I have: [FAILURE_DESCRIPTION_AND_CODE]. After the interview, guide me through reduction in rounds. For each round, tell me exactly what to remove or replace (for example "delete the database call and return a fixed object"), what result to expect, and what each outcome means: IF the problem disappears THEN the removed part is involved, restore half of it; IF it remains THEN keep the part removed. Use a binary-search approach on files, functions, inputs, and configuration. At the end, produce the minimal reproduction: a short code listing and the commands to run, the observed and expected results, the environment details, and a bug report template that a maintainer could use. Also suggest a regression test that captures the case. Do not guess the cause until the example is small.
