collect_ftd extended one list of dicts across all 411 fails-to-deliver archives -- 22.9 million records, some fifteen gigabytes of Python objects, and the job was OOM-killed at that line on 16 GB. Each archive now becomes a frame as it arrives and they are concatenated once; the same records as Arrow are under two gigabytes. Same rows, same order.
The job header asked for ruff>=0.11,<1, which is whatever ruff released this morning. A new minor added RUF100, four previously clean noqa directives became errors, and fund-holdings-nport published nothing for seventeen days; the same morning could have stopped all fifteen datasets at once. The version is now chosen deliberately, and upgrading it is a commit where somebody also fixes whatever it finds.
