v14.9: add smart text fallback layer - 4-tier degradation
- Add 'Smart Text' as Layer 2 (between CSS and ARIA snapshot): - _extract_keywords(): extract hints from CSS selector + description - :has-text() text, [placeholder], [aria-label], tag->role mapping - Chinese description keyword extraction (strip action verbs/suffixes) - Quoted text extraction from description - _try_smart_text_click(): Role+Text -> pure Text -> Label strategies - _try_smart_text_fill(): Placeholder -> Label -> DescLabel strategies - New automator.py methods for Playwright native locators: - click_by_text(): get_by_text exact then fuzzy - fill_by_placeholder(): get_by_placeholder exact then fuzzy - click_by_role_fuzzy(): get_by_role with exact=False - fill_by_label(): get_by_label for input fields - Degradation chain now: CSS -> Smart Text -> ARIA Snapshot -> AI Screenshot - Layer 2 (Smart Text) is zero-cost (<100ms, 0 tokens, 0 API calls) - Expected to recover ~80% of CSS selector failures automatically

## ✅ v14.9 四层降级——智能文本直达(2026-03-28)
9+
10+
### 问题背景
11+
12+
v14.8 修复了 ARIA API 兼容性,但选择器错误仍频繁发生——AI 生成蓝本时很容易写出错误的 CSS 选择器。v14.7/v14.8 的降级链是 CSS → ARIA 快照 → AI 截图,但 ARIA 快照需要 5 秒超时获取整个树,AI 截图需要 3-8 秒 + 1000 token。需要一个**零成本、零延迟**的中间层来处理最常见的选择器错误。
13+
14+
### 核心思路:从 OpenClaw 学到的不只是 ARIA 快照
15+
16+
OpenClaw 不容易出错的根本原因是"**每一步都读页面**"。我们不需要像它那样花 AI 调用,但可以**从已有信息中提取线索**
17+
- CSS 选择器 `button:has(> svg[class*='Plus'])` 虽然错了,但告诉我们目标是一个 **button**
18+
- description `"点击记一笔按钮"` 告诉我们按钮上有 **"记一笔"** 这个文字
19+
- `input[placeholder='请输入金额']` 直接告诉我们 **placeholder** 是什么
20+
21+
用这些线索直接调用 Playwright 原生定位器(`get_by_text`/`get_by_role`/`get_by_placeholder`),不需要获取 ARIA 快照,零开销!
22+
23+
### 新的四层降级策略
24+
25+
```
26+
第1层 CSS 选择器(0ms, 0 token)→ 95% 成功
27+
↓ 失败
28+
第2层 智能文本直达(<100ms, 0 token)→ 挽回 ~80% ← 新增!
29+
↓ 失败
30+
第3层 ARIA Snapshot(200-5000ms, 0 token)→ 挽回 ~60%
31+
↓ 失败
32+
第4层 AI 截图坐标(3-8s, 1000+ token)→ 最终兜底
33+
```
34+
35+
### 变更清单
36+
37+
#### 新增 `automator.py` 方法
38+
39+
- `click_by_text(text)``page.get_by_text()` 先精确后模糊
40+
- `fill_by_placeholder(placeholder, text)``page.get_by_placeholder()` 直达输入框
41+
- `click_by_role_fuzzy(role, name)``page.get_by_role()` 模糊匹配
42+
- `fill_by_label(label, text)``page.get_by_label()` 通过标签定位
43+
44+
#### 新增 `blueprint_runner.py` 方法
45+
46+
- `_extract_keywords(target, desc)` — 从CSS选择器和description提取定位线索
47+
- 提取 `:has-text('xxx')` 中的文本
48+
- 提取 `[placeholder='xxx']` 中的 placeholder
49+
- 提取 `[aria-label]`/`[title]`/`[name]` 属性值
50+
- 从元素标签推断 ARIA role(button→button, a→link, input→textbox)
51+
- 从中文 description 去掉动作词(点击/输入/填写...)提取核心关键词
52+
- 从引号中提取文字(如"点击'记一笔'按钮"→"记一笔")
53+
- `_try_smart_text_click(target, desc)` — 三策略顺序尝试:Role+Text → 纯Text → Label
54+
- `_try_smart_text_fill(target, value, desc)` — 三策略顺序尝试:Placeholder → Label → DescLabel
55+
- `_click_with_fallback` / `_fill_with_fallback` 升级为四层
56+
57+
### 以"记一笔"按钮为例的降级模拟
58+
59+
```
60+
CSS: button:has(> svg[class*='Plus']) → 失败(SVG class 不匹配)
61+
智能文本:
62+
1. _extract_keywords 提取: role_hint="button", text_hints=["记一笔"]
63+
2. click_by_role_fuzzy("button", "记一笔") → 成功!page.get_by_role("button", name="记一笔") 精确找到
64+
↑ 零ARIA快照、零AI调用、<100ms
65+
```
