 - 本轮补充：terminal input parser 现在把 xterm modified navigation modifier 范围扩展到 `2..16`，覆盖 meta/shift+meta/ctrl+meta 组合（如 `CSI 1;10D`、`CSI 1;16C`）以及对应 Home/End/Delete/PageUp/PageDown 序列。
 - 本轮补充：terminal CSI-u/kitty keyboard parser 现在按 modifier bitfield 解码 `9..16` 扩展组合，把 meta/shift+meta 映射到现有 alt key surface，把 ctrl+meta 组合保留为 ctrl key，覆盖 `CSI 98;9u`、`CSI 97;13u` 等序列。
 - 本轮补充：terminal CSI parser 把 DA/device attributes (`CSI c`、`CSI >c`、`CSI =c`) 归入 report action，并在 terminal parser dispatcher 中作为 `TerminalActionReport` 暴露。
+- 本轮补充：terminal CSI parser 现在保留多参数 DA/device-attributes response 的完整 code list，例如 `CSI ?62;1;2;6c` 不再只留下首个 terminal type code。
 - 本轮补充：terminal CSI parser 接受 `CSI a`/`CSI e`/`CSI \`` cursor alias final bytes，并映射到已有 cursor-forward/cursor-down/cursor-column actions。
 - 本轮补充：terminal CSI parser 接受 ECMA `CSI Ps j` / `CSI Ps k` HPB/VPB backward cursor final bytes，并映射到已有 cursor-back/cursor-up actions。
 - 本轮补充：terminal CSI parser 接受 DEC private mode `?1047h/l` alternate-screen buffer 和 `?1048h/l` save/restore cursor，复用已有 mode/cursor actions。

 - `internal/tui`: terminal CSI parsing now accepts ECMA HPB/VPB final bytes `CSI Ps j` / `CSI Ps k` as cursor-back and cursor-up actions.
 - `internal/tui`: terminal CSI parsing now accepts DEC private mode `?1046h/l` alternate-screen switching, `?1047h/l` alternate-screen buffer, and `?1048h/l` save/restore cursor variants using distinct mode/cursor action surfaces.
 - `internal/tui`: terminal CSI parsing now emits report actions for DECREQTPARM terminal-parameters queries such as `CSI x`, preserving code and private marker fields.
+- `internal/tui`: terminal CSI parsing now preserves the complete code list from multi-parameter DA/device-attributes responses such as `CSI ?62;1;2;6c` instead of dropping capability flags after the first code.
 - `internal/tui`: terminal CSI parsing now emits report actions for DECRQM mode requests such as `CSI 4$p` and `CSI ?25$p`, preserving mode code and private marker fields.
 - `internal/tui`: terminal CSI parsing now emits report actions for xterm window manipulation/report queries such as `CSI 14t` and `CSI 18t`, preserving code/private marker fields and structured dimensions for `CSI 4;height;width t` and `CSI 8;rows;cols t`.
 - `internal/tui`: terminal CSI parsing now emits cursor actions for TBC tab-clear sequences such as `CSI g` and `CSI 3g`, preserving the clear-current/all code.
