 - 本轮补充：terminal CSI parser 把 DECREQTPARM terminal-parameters (`CSI x`) 归入 report action，保留 code/private marker。
 - 本轮补充：terminal CSI parser 现在保留 DECREPTPARM/terminal-parameters response 的完整参数列表，例如 `CSI 2;1;1;112;112;1;0x` 不再只留下 report code。
 - 本轮补充：terminal CSI parser 把 DECRQM mode request (`CSI Ps $ p` / `CSI ? Ps $ p`) 归入 report action，保留 mode code 和 DEC private marker。
+- 本轮补充：terminal CSI parser 现在保留 DECRQM mode-request 的完整参数列表，例如 `CSI ?25;1000$p` 会同时暴露首个 mode code 和原始 params。
 - 本轮补充：terminal CSI parser 把 CPR cursor-position responses (`CSI row;col R` / DEC private `CSI ? row;col R`) 归入 report action，结构化暴露 row/column 并保持 visible-text stripping。
 - 本轮补充：terminal CSI parser 继续补齐 DEC 私有 DSR/CPR，`CSI ?6n` 现在归入 cursor-position report query，`CSI ?row;col;page R` 会保留 page 元数据。
 - 本轮补充：terminal CSI parser 把 xterm window manipulation/report (`CSI t`) 归入 report action，覆盖常见 `CSI 14t`/`CSI 18t` 查询，并把 `CSI 4;height;width t` 与 `CSI 8;rows;cols t` 的 pixel/text-area 尺寸参数结构化暴露。
