TTS grade for qwen3.6-35b-a3b-6bit-mlx: 49/100 Critical (same model that
scored 82 on LFU). File doesn't parse + bounded-concurrency is fake
(1 worker + inner semaphore = real concurrency 1). Per-task signal:
strong on data-structures, weak on async-pipeline work.
Schema: prompt_id + PILLARS_BY_PROMPT so each entry uses its own 5 pillars.
TODO_submission_tool.md sketches the grade-as-a-tool idea for later.
