Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: ⚪ Minimal · up to This PR adds unit tests without changing shipped behavior. The remaining follow-ups are limited to accurately labeling mocked coverage and improving test maintainability, so no actionable merge-blocking risk remains after normal checks and review.

678-733: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueThe exhaustive key list is brittle.
The literal repeats all 50 method names. Every added method breaks this test and forces a manual list edit. If the goal is to detect accidental removals, assert a required subset and the count instead.

Lines 69, 73, 78, 86, and 89 assert complete error strings that are copied from the implementation template in
hubClientTransportBasics.ts. The coding guidelines prohibit hard-asserting error text in tests. Assert the stable, machine-readable parts instead:code,status, and the interpolated values.♻️ Suggested assertion style
- expect(error.message).toBe('Request timed out after 12000ms: POST /web/projects'); + expect(error.message).toContain('12000'); + expect(error.message).toContain('POST'); + expect(error.message).toContain('/web/projects');As per coding guidelines: "测试不得复制被测实现的 switch、测试常量字符串、硬断错误文案或 mock 被测函数本身".

Inline comments:
In `@app/shared/src/chatview/adapterMapBlock.test.ts`:
- Around line 859-898: The skipped-kinds tests lack coverage for the valid
TextTranscriptBlock case. Add a typed block with kind text to the mapBlock test
suite and assert that mapBlock returns null, keeping the existing unknown-kind
test focused on invalid input.
- Line 1: Update the real_tested marker at the top of the adapterMapBlock test
fixture from true to false, accurately indicating that the suite uses local
fixture inputs rather than real login, model/API, or packaged Desktop testing.
Apply the same fix in `@app/shared/src/hub/hubClientApiExtended.test.ts` around
lines 1 - 4: The same test-realism labeling issue applies with a more precise
qualification.

Summary
延续 #1765–#1776，落地 Lane D 前端测试补债 (#1764) 第八批：给 3 个模块补 169 个单元测试。不改任何产品代码。
为什么选它
hubClientApiExtended.ts（273 行）：50 个 API 方法的工厂层，transport 接线 + payload builder 组合的端到端契约。hubClientTransportBasics.ts（152 行）：传输层基础工具（abort/network 判定、header 组装、token 刷新条件）——真实网络回归风险集中地。chatview/adapterMapBlock.ts（293 行）：mapBlock 此前无任何直接测试（只有经 blocksToTranscriptItems 的间接覆盖）。覆盖范围
