 本轮补充：scripted interaction action replay 现在接受 DOM `beforeinput`/`input` event 的 `data` payload，`insertText` 等文本输入进入 prompt typing，`insertFromPaste`/drop variants 进入现有 pasted-content 路径。
 
+本轮补充：scripted interaction DOM input replay 现在会把 `deleteContentBackward`、`deleteWordBackward`、`deleteHardLineForward`、`insertLineBreak` 等 `inputType` 映射到已有 prompt key action，覆盖浏览器录制的删除和换行事件。
+
 本轮补充：scripted interaction step 现在接受 `expect`/`expected`/`assertions`/`checks`/`verify`/`then`/`after` 等 expectation wrapper object，可把嵌套的 prompt/event/dialog/snapshot/screen/task/vim/viewport 断言映射到已有 `expect*` 字段。
 
 本轮补充：scripted interaction expectation wrapper 现在也接受 assertion/check 数组，数组元素可用 `type`/`kind`/`name`/`target` 等 discriminator 搭配 `value`/`payload` 声明 prompt/event/dialog/snapshot/screen/task/vim/viewport 断言，减少官方脚本 fixture 的结构改写成本。

 - `internal/tui`: interaction script key event objects now treat DOM `keyup`/`keyUp`/`key-release` payloads as no-op replay events, so browser/Playwright recordings that include both keydown and keyup do not duplicate prompt input.
 - `internal/tui`: interaction script key event replay now also skips DOM `Dead`/`Process`/IME key names, `isComposing` payloads, and composition event types, preventing IME/dead-key recording artifacts from being inserted as literal prompt text.
 - `internal/tui`: interaction script action replay now accepts DOM `beforeinput`/`input` events with `data` payloads, mapping text insertion to prompt typing and `insertFromPaste`/drop variants to the existing pasted-content path.
+- `internal/tui`: interaction script DOM input replay now maps deletion and line-break `inputType` values such as `deleteContentBackward`, `deleteWordBackward`, `deleteHardLineForward`, and `insertLineBreak` onto existing prompt key actions.
 - `internal/tui`: interaction script mouse payloads now infer release state from event type aliases such as `mouseup`, `pointerUp`, and `touchend`, while explicit release booleans still take precedence.
 - `internal/tui`: interaction script mouse payloads now infer SGR wheel buttons from DOM/compact wheel inputs such as `wheel`, `mousewheel`, `scrollUp`/`scrollDown`, `direction`, `deltaY`, and legacy `wheelDelta`, allowing recorded wheel events to drive viewport scrolling.
 - `internal/tui`: interaction script mouse payloads now accept DOM `which` and `buttons`/`buttonState` bitmasks and map them to SGR left/middle/right buttons so recorded secondary or auxiliary clicks are not treated as primary clicks.
