内容

新增只读分析脚本 research/ui/analyze_output_trace.py：把场景产物里的三份诊断文件拼成一张时间线。

  • 读 output-trace.jsonl（输出块/输入块、终端号、网格尺寸、repaint 标记）；
  • 读 actions-progress.jsonl 或 *-progress.jsonl（阶段与 t_ms）；
  • 读 selection-discard.jsonl（丢弃原因、行号、字节/列数）；
  • 对每条丢弃打印前后阶段，并列出 ±2 秒内的重绘批次及其消费时刻网格。

实际输出示例（本地全绿运行）

== run-el4xnl28/local-0
   discard row-text-changed row=0 between live-selected and invalidated-copy-rejected saved_bytes=23 current_bytes=17 saved_columns=74 current_columns=74
      repaint t=471562 terminal=1 columns=111 rows=7 bytes=210
      repaint t=471640 terminal=1 columns=149 rows=10 bytes=231
      repaint t=471687 terminal=1 columns=111 rows=7 bytes=210

即同一轮里重绘批次分别以 111×7 与 149×10 被消费——正是 #194 需要的"消费时刻几何"证据。

A read-only script prints, per discard, the surrounding phases and the repaint batches within two seconds together with the grid each batch was consumed at, so artifacts can be interpreted without bespoke scripts.
