test(android-2b): 真机中文候选词 proof——拼音组词经 commitText 落到 Windows
V6 的判据是「手机中文输入法能把汉字送进远端」，此前只能靠人手点候选词。 实测发现两条关键事实，决定了 proof 的可行形态： 1. adb keyevent 相当于物理键盘输入，中文 IME **不组词**，字母原样透传到 Activity.onKeyDown——所以驱动候选词必须用 adb input text（走 IME）。 2. IME 自己的按键视图对 uiautomator 不可见（dump 里只有我们 App 的 15 个节点）， 中/英切换按钮读不到坐标，只能按截图标定一次点击位；且该按钮**有状态**， 于是写成幂等重试：先试，只收到字母才翻转模式再来一次。 跑通结果：讯飞拼音 nihao + 空格 -> commitText 2u -> 靶窗收到 U+4F60 U+597D。 这补上了方案风险 R1（vivo ROM + 第三方中文 IME 行为未观测）的核心一环。

# 2b V6 on-device CHINESE: drive the IME through pinyin + candidate selection.
|
||||
# ASCII-only source. Non-ASCII expectations are built from code points.
|
||||
#
|
||||
# Measured path differences (2026-10-30, vivo S6 + iFlytek IME):
|
||||
# - `adb input keyevent <letter>` behaves like a HARDWARE keyboard: the IME
|
||||
# does not compose, the event lands in Activity.onKeyDown and our printable
|
||||
# unicodeChar branch sends it as text. So keyevents CANNOT exercise Chinese
|
||||
# candidate selection.
|
||||
# - `adb input text <latin>` is delivered to the IME, which composes it;
|
||||
# SPACE (keyevent 62) then accepts the highlighted candidate, and the Hanzi
|
||||
# arrive at RemoteInputConnection.commitText.
|
||||
# This script therefore types pinyin with `input text` and commits with SPACE.
|
||||
#
|
||||
# Acceptance: the Windows target window receives the exact Han characters the
|
||||
# IME committed - Chinese input works end to end over protocol v3.
|
||||
# Not covered: swipe/handwriting input, browsing the candidate list.
