How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🔵 Low · up to This PR adds and reorganizes unit tests without changing product behavior. A bounded merge-readiness risk remains because some assertions may preserve unstable invalid-input behavior, while duplicated timing and protocol values can drift from production contracts; the PR is mergeable with explicit owner awareness or follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 36-40: Remove the negative-input artifact assertions from
app/shared/src/context/breakdown.test.ts at lines 36-40 and 235-244, or define
and implement a stable negative-input behavior in estimateTokens and the related
breakdown logic before updating those tests; do not preserve assertions for -0
or negative scaled bucket values.
In `@app/shared/src/ui/toast/__tests__/toastStore.test.ts`:
- Around line 5-6: Centralize the toast timing contract by exporting documented
values for the default duration and exit animation from the production toast
implementation, then import and reuse that contract in the toastStore tests
instead of redefining 4000 and 300. In the tests, use
vi.advanceTimersToNextTimer() only when asserting timer ordering, while
retaining explicit time advancement for exact timing boundary behavior.

🌐 Web query:
Vitest 4.1.10 documentation: does vi.advanceTimersToNextTimer() advance exactly one pending fake-timer callback?
💡 Result:
Yes, vi.advanceTimersToNextTimer is designed to advance to the next available timer, effectively processing one scheduled timer event at a time [1][2]. Internally, the implementation of this method iterates through a clock (defaulting to 1 step) and calls the next timer, followed by a tick of zero milliseconds to ensure that any resulting tasks are flushed [3]. This behavior allows you to chain calls to the method to manage and assert against timers individually, making it useful for testing sequences of timer-based events [1][3].

Keep toast timing values in one contract.
The test repeats the production values 4000 and 300 under different names. Export a documented timing contract and import it in the test. Use vi.advanceTimersToNextTimer() only for timer-order assertions; keep explicit boundary checks where exact timing is part of the behavior.

Summary
延续 #1765、#1766、#1767，落地 Lane D 前端测试补债 (#1764) 第四批：给 3 个纯逻辑模块补 113 个单元测试（净增）。不改任何产品代码。
为什么选它
notificationIntents.ts（266 行）：通知 intent 归一化/别名/必填校验/导航映射——歧义字段优先级与缺失必填 id 的回归风险，最适合单测锁住。context/breakdown.ts（164 行）：token/cost 估算与分段渲染纯函数，边界（0/负数/-0/未知 role）易错。ui/toast/toastStore.ts：Zustand 单例 store，补 pause/resume/定时器边界；并将既有 11 测试合并升级为 30（消除__tests__与 co-located 重复文件）。覆盖范围
Test plan
vitest run新文件 — 144/144 通过（含既有 Toast.test.tsx）tsc --noEmit全包 0 错误关联
